 AB The objectives of this study were to evaluate thermal treatments of
    vapor heat in the control of Anastrepha serpentina on zapote and to
    determine tolerance of zapote mamey fruits to the treatments. The
    fruits not were damaged internally by the heat treatment when exposed
    to 43 degrees C(.)120 min(-1). The fruits reached eating ripeness in 8
    days at 25 degrees C, with rapid changes in the pulp color and weight
    loss. In contrast, at 10 degrees C they maintained greater firmness and
    prolonged shelf life, but exhibited greater damage in the vascular
    bundles. Mortality of the fruit fly eggs and larvae was 100 % with
    controlled atmosphere vapor heat treatment at 43 degrees C(.)120
    min(-1). Fruits not were damaged by the application vapor heat; larvae
    were easily killed by the CA at 40 degrees C(.)120 min(-1), but eggs
    were more resistant and hatched at 25 degrees C after the 8 days of
    storage.

 AB Objective. To analyze the current situation of teaching occupational
    medicine (OM) in academic programs and medical schools in Mexico.
    Material and methods. A descriptive survey was conducted and schools
    were identified through the main directories of medical schools. For
    the analysis of information descriptive and inferential statistics were
    used. Results. A total of 75 medical schools were identified. In 39
    (52%) the subject is mandatory, with a predominance in public schools
    (p < 0.02). Among the schools that offer the subject, only 15 (38%)
    have professors specialized in OM. Conclusions. Disparity in teaching
    basic aspects of OM in medical schools explains the little development
    and social and professional recognition of the specialty; it also
    highlights serious problems for public health, derived from the lack of
    prevention of risks in work environments.

 TI The use of gloves as protector factor against scorpion stings during
    corn picking in the state of Guerrero, Mexico
 SO SALUD PUBLICA DE MEXICO
 LA Spanish
 DT Article
 DE scorpion venoms; occupational health; costs; gloves, protective; Mexico
 AB Objective. Identify factors associated with scorpion stings among farm
    workers who pick corn in the Mexican state of Guerrero. Material and
    Methods. Cross-sectional survey in 14 randomly selected communities in
    the state of Guerrero. Simple frequencies were obtained and bivariate
    analysis was used to identify factors associated with scorpion stings
    while picking corn. Odds ratio was estimated to evaluate the magnitude
    of the effect. Results. The incidence of scorpion stings was 15% (500/3
    294) in 2003. Use of gloves was associated with a dramatic reduction in
    risk of scorpion stings to the hands (OR = 0.11; IC95% 0.06-0.18).
    Scorpion stings are a frequent occupational health issue for farm
    workers. If the results of this survey were reproduced in an unbiased
    trial, the implication would be that gloves could prevent 133 stings
    per 1 000 farm workers who currently do not use gloves. The cost of
    medical attention, transportation and time away from work due to a
    scorpion sting totaled 505.90 pesos (46 US dollars). Conclusions. The
    use of gloves by farmers who live in regions where scorpions are
    endemic should be promoted. The supply network for anti-scorpion serum
    should also be extended to all rural areas where very toxic species are
    predominant and farmers should be educated about the importance of
    seeking timely medical care at health clinics.

 AB Objective. Evaluate the relationships between AgNORs polymorphisms and
    squamous intraepithelial lesions (SIL) and squamous cell carcinoma
    (SCC) with HPV infection. Materials and methods. A study was carried
    out on sixty women from the state of Guerrero, Mexico. HPV detection
    was performed by PCR.AgNORs were identified by argentic impregnation.
    One hundred cells per slide were counted and classified according to
    the polymorphism of AgNORs dots; typical (spherical) and atypical
    (large, kidney-shaped and clustered). Results. A total of 100% of the
    cases were positive for HPV infection. Nine different high-risk HPV
    genotypes were found, type 16 was the most common (48.6%). The AgNORs
    showed a significant decrease in spherical shape according to
    neoplastic development. The three atypical shapes showed a significant
    increase in SIL and SCC (p-trend < 0.001). Conclusions. AgNORs
    polymorphism rises progressively according to the grade of histological
    lesions that can be useful as a prognosis for progression of SCC.

 AB The Sierra Madre del Sur a Mesozoic-Cenozoic magmatic arc in southern
    Mexico, was studied deformed plutons from two transects were using U-Pb
    Zircon geochronology Undeformed to slightly, de sampled at the limit
    between the Guerrero and Xolapa terranes, in order to constrain the
    magmatic history, nature of the basement and terrane boundaries. Four
    samples from the Zihuatanejo, Guerrero, transect within the Guerrero
    terrane, Yielded crystallization ages of 41.8 +/- 1.4, 43.4 +/- 1.6,
    40.8 +/- 1.4 and, 41.8 +/- 4.6 Ma. No inherited Zircons were detected
    in these plutons indicating that pre-existing Zircons from continental
    basement or sediments are not a significant component in these rocks.
    Fivesomples./rom the Atoyac, Guerrero transcect within the Xolapa
    terrane, yielded crystallization ages of 53.5 +/- 1.9. 52.7 +/- 1.9,
    57.3 +/- 2.2, 54.4 +/- 1.7. and 57.0 +/- 2.1 Ma, analogous to the ages
    reported for the Acapulco intrusive. One sample of this transect
    yielded an age, of 40.2 Ma with an inherited component of 58-64 Ala,
    similar to the ages determined for the first five samples. Several
    clusters of Mesozoic inherited zircons with ages of 72-74 Ma, 83-87 Ma,
    90-92 Ala, 105-111 Ma and, 143-153 Ma, indicate that the magmatism in
    the Xolapa terrane was active since the Jurassic, and that multiple
    episodes of magmatism occurred during the Cretaceous. Inherited zircons
    also indicate that processes of assimilation and recycling of previous
    intrusive bodies have played an important role in the evolution of the
    Xolapa Complex. Older Paleozoic of the (similar to 320 Ma: similar to
    360 Ma) and Grenvillian (similar to 960-1085 Ala) inherited zircons
    ages suggest an affinity of the Xolapa Complex with the Acatlan and
    Oaxaca Complexes, even though the metasedimentary basement of the
    Xolapa complex (of unknown age) may he the source of these Paleozoic
    and Grenvillian zircons. The presence of inherited zircons in the
    Atoyac transect suggests that the limit between the Xolapa and Guerrero
    terranes is located between these two transects.

 AB Dormitator is among the most important fish genera in the Mexican
    Pacific coastal lagoon systems. In Tres Palos Lagoon, the Fat Sleeper
    Dormitator latifrons is one of the most significant species based on
    catch volume, although it is only consumed locally. Very little
    information exists on this species' parasitofauna. Composition and
    temporal variation in the metazoan parasite community structure of
    Dormitator latifrons from Tres Palos Lagoon (99 degrees 47' W, 16
    degrees 48' N), Guerrero, Mexico, were determined using seasonal
    samples taken between April 2000 and June 2002. Ten parasite species
    (55 817 individuals) were recovered from 219 examined hosts. These
    species included eight helminths (Ascocotyle (Phagicola) longa,
    Echinochasmus leopoldinae, Clinostomum complanatum, Pseudoacanthostomum
    panamense, Saccocoelioides lamothei, Parvitaenia cochlearii,
    Contracaecum sp. and Neoechinorhynchus golvani) and two crustaceans
    (Argulus sp. and Ergasilus sp.). Five of the helminth species exhibited
    seasonal variation in their infection dynamics associated with
    environmental changes during the dry and rainy seasons. The variations
    in the infection dynamics generated changes in the community structure
    over time. Rev. Biol. Trop. 56 (3): 1419-1427. Epub 2008 September 30.

 AB From a socioepistomological view, the intertwined social practices and
    self-generated social representations, establish a dialog different
    from the prevailing school discourse. In this report, we reflect about
    mathematics majors' argumentations about the geometric construction of
    the quadratic and logarithm functions using a geometric dynamic system.
    This work has been developed using the engineering didactic as a
    research method hence we include some reflections from the mathematical
    school discourse, from the epistemology of the logarithm function, and
    a brief state of the art about these notions.

 AB Systemic lupus erythematosus in some cases is characterized for
    development of thrombotic events with a significantly increased risk of
    mortality. The frequencies and clinical associations of
    Ser(413)/Cys(413) PAI-2 polymorphism in 40 systemic lupus
    erythematosus, 50 rheumatoid arthritis patients, and 100 healthy
    subjects frequency were investigated. The Ser(413)/Ser(413) genotype
    was 53% (lupus), 36% (rheumatoid arthritis), and 35% (healthy
    subjects). The Ser(413) allele was associated with systemic lupus
    erythematosus (P =.04, odds ratio 1.76, 95% confidence interval =
    1,01-3.06). In all, 4 patient carriers of Ser(413)/Ser(413) genotype,
    developed thrombotic events. The lupus patients identified with
    Ser(413)/Ser(413) genotype showed an increased damage (57%), compared
    with Ser(413)/Cys(413) and Cys(413)/Cys(413) genotypes, with
    significant difference (P =.03). These findings suggest an association
    of Ser(413)/Ser(413) genotype with greater damage index score and
    Ser(413) allele with Systemic lupus erythematosus. Besides, PAI-2
    polymorphism Could be related with thrombotic phenomena in systemic
    lupus erythematosus

 AB 3,6-Dinitrodurene (1,2,4,5-tetramethyl-3,6-dinitrobenzene), C10H12N2O4,
    has been crystallized in two polymorphic forms which may be
    distinguished by their colours in the solid state. Polymorph I gives
    clear colourless prismatic crystals, while polymorph II crystallizes in
    the dark and under an inert atmosphere as irregular purple blocks. Both
    forms belong to the space group C2/c, with both asymmetric units
    containing two half-molecules. One molecule is located on an inversion
    centre and the other lies on a twofold axis. The polymorphism arises
    from different orientations of the twofold axis: in form I, this axis
    passes through the mid-points of two C-C bonds of the benzene ring and,
    as a consequence, all atoms in the asymmetric unit are in general
    positions. In form II, the N atoms of the nitro groups and the C-ipso
    atoms are located on the binary axis. Comparing phases I and II,
    slightly different conformations are observed for the nitro
    substituents, while the stacking structures are very similar.

 AB Background: This study was conducted to determine human papillomavirus
    (HPV) types in women with cervical cancer (CC) and normal cervical
    cytology in the Southern region of Mexico, and to know the contribution
    of HPV types and cofactors in cervical cancer etiology. Methods: A
    case-control study was performed in 133 women with CC and 256 controls.
    HPV detection was done by MY09/11 and GP5+/GP6+ PCR systems and typing
    by restriction fragment length polymorphism or DNA sequencing. Results:
    HPV was found in 100% of CC and 35.5% of controls. The genotype
    distribution in CC was: HPV 16 (66.8%), 18 (9%), 31 (7.5%), 45 (4.5%),
    58 (3.7%), 69 (3%), 52 (1.6%), 6, 11, 33, 56, and 67 (0.8% each). Among
    controls, HPV 33 followed by HPV 16 were the most frequent. Cervical
    cancer was associated with HPV 16 (OR = 573.5), HPV 18 (OR = 804.4),
    and undetermined risk HPV (types 67 and 69) (OR = 434.3). Age at first
    intercourse <16 years (OR = 9.6) and >= 3 births (OR = 16) were
    significant risk factors for CC. Conclusions: HPV 16, by far, is the
    most frequent type in CC. HPV 16 and 18 are responsible for 75.8% of
    the CC cases and high-risk HPV for 94.7%, which is useful data to take
    into account in vaccination programs. HPV 33 is the most frequent type
    in controls and high-risk HPV are more common than low-risk HPV. (C)

 AB The length-weight relationship parameters and seasonal reproductive
    cycle are recorded for six commercially important fish species caught
    in the coastal lagoon of Tres Palos. The length-weight information is
    new to the literature for three of these species (spot cichlid, spotted
    sleeper, Pacific fat sleeper) and is within the expected range for the
    other three (widehead sea catfish, three spot cichlid, white mullet).
    Differences between sexes are statistically significant for four
    species and deviations from isometric growth are indicated in three
    species. The reproductive period for the Pacific fat sleeper differed
    substantially from the period reported for this species in Ecuadorian
    waters.

 AB The dietary crude protein (CP) can be reduced by four percentage units
    when corn-soybean meal (SBM) and crystalline amino acids (AA) are used
    to formulate diets for growing pigs. With sorghum the results have not
    been conclusive. Therefore, two experiments were conducted to determine
    the lowest CP value in sorghum-SBM, AA supplemented diets, using plasma
    urea nitrogen (PUN), growth performance, and carcass characteristics as
    the response criteria. In Experiment 1, the percentage of CP in the
    treatments was as follows: T1) 16.0, control diet; T2) 14.5; T3) 13.0;
    and T4) 11.5. Eight gilts were used in a cross-over design with four
    periods of 7 days each. Blood samples were collected the last day of
    the period to determine PUN. Several regression models were used to
    obtain the best prediction of PUN. The lowest PUN indicated that CP can
    be reduced from 16 to 11.5%. The best regression model was the
    nonlineal exponential, which can predict that the minimum plasma urea
    concentration is obtained with 10.48% of CP. In Experiment 2, the
    percentage of CP and metabolizable energy Mcal kg-1) were as follows:
    T1) 16, 3,265, control; T2) 16, 3.165; T3) 14.5, 3.265; T4) 14.5,
    3.165; T5) 11,5, 3.265; and T6) 11.5, 3.165. Thirty barrows were
    assigned in a completely randomized design with a 3x2 factorial
    arrangement, six treatments and five replicates of one barrow
    (individually penned) for each treatment. The lowest CP reduced the
    average daily gain, feed gain ratio, and PUN. The lowest ME reduced the
    feed gain ratio. These results indicate that reducing CP diminishes
    PUN, although some productive variables are affected.

 AB Objective: To identify birth weight cutoffs to predict overweight in
    school children and adolescents from Chilpancingo, Mexico, in 2004.
    Methods: Six hundred and sixty-two male and female children between 5
    and 13 years old were selected by probability sampling. Birth weight
    measures were extracted from vaccination cards. The school children's
    nutritional status was defined using specific body mass index (BMI)
    cutoffs according to sex and age. Predicting equations were built using
    linear regression models. Areas under the receiver operating
    characteristic (ROC) curves were calculated and two-graph (TG) ROC
    curves were plotted, respectively, to detect global accuracy and to
    identify birth weight cutoffs corresponding to the intersection of
    sensitivity and specificity curves.
    Results: Overweight prevalence was higher in female (46%) than male
    school children (38.5%). Among adolescents, overweight prevalence was
    also higher in females (43.5%) than males (38.9%). BMI average and
    birth weight deciles showed a linear relation. Areas under ROC curves
    showed values >= 78% in each stratum of sex and age, depicting a
    difference by sex in adolescents. TG-ROC curves showed that birth
    weight cutoffs were slightly higher in boys than in girls, and the
    sensitivity/specificity intersections were >= 0.70.
    Conclusions: The study results showed that birth weight cutoffs can be
    used as overweight markers in childhood and adolescence, being useful
    as a screening strategy to detect risk groups.

 AB We analyzed metazoan parasite community composition in the three-spot
    cichlid Cichlasoma trimaculatum using seasonal samples taken between
    April 2000 and November 2002 from the Tres Palos Lagoon, Guerrero,
    Mexico. A total of 231 hosts were examined. Of the 12 parasite species
    recovered (40,969 individuals), 10 were helminths: Ascocotyle
    (Phagicola) longa, Austrodiplostomum compactum, Cladocystis trifolium,
    Clinostomum complanatum, Crassicutis cichlasomae, Posthodiplostomum
    minimum, Pseudoacanthostomum panamense, Neoechinorhynchus golvani,
    Southwellina hispida, and Contracaecum sp. The remaining 2 were the
    crustaceans Argulus sp. and Ergasilus sp. The community was generally
    poor in number of parasite species, and characterized by a high number
    of generalist parasites and fewer cichlid specialists. Four of the 5
    common parasite species exhibited seasonally variable infection
    dynamics associated with environmental differences between the dry and
    rainy seasons. This variation in the dynamics of infection in the
    common parasite species generated changes in community structure over
    time. Clear patterns were not observed, however, indicating that this
    community has low predictability, as has been suggested for other
    parasite communities from freshwater fish.

 AB A new haploporid trematode, Saccocoelioides lamothei n. sp., is
    described from the intestine of the Pacific fiat sleeper, Dormitator
    latifrons (Richardson, 1844) from 2 coastal lagoons of Guerrero,
    Mexico. The new species is characterized by the presence of diffuse
    eye-spot pigmentation in the forebody, 2 sac-like caeca ending
    pretesticularly, ventral sucker pre-equatorial and miracidium with
    pigmented eye-spots in eggs. It differs from all other congeneric
    species by having a small, pyriform to slightly elongated body, a short
    but conspicuous prepharynx and sac-like caeca terminating
    pretesticularly, an extreme posterior position of the testis, a small
    spherical to elongated ovary, vitelline follicles irregular in shape
    and size and reaching the ovary level, the uterus extending from the
    testicular zone to the acetabular region, with numerous relatively
    large eggs.

 AB Ultrasonic technique has been successfully used in a Non-Destructive
    Testing (NDT) of materials. This method aims to characterise the
    physical properties of reflectors in terms of their location, size,
    orientation, etc. To perform ultrasonic NDT, a transmitting/receiving
    transducer is moved along a known path producing a reflectivity map of
    the tested material. In order to characterise flaws, an innovative
    methodology of ARTMAP network and Wavelet Transform is presented. It
    consists of two non-supervised networks which are then used to build a
    mapfield. The mapfield is constructed using the neural networks output
    trained with time-scale information of perpendicular reflectivity maps.

 ID SOLVENT-FREE; THIOUREAS
 AB The title compound, C11H20N2O2S, is an enantiomerically pure
    heterocycle-substituted thiourea synthesized under solvent-free
    conditions. The thiourea unit adopts a ZZ conformation, with the
    HN-(C=S)-NH core almost planar and the tetrahydrofurfuryl groups placed
    below and above this plane. The whole molecule thus approximates to
    noncrystallographic C-2 symmetry. Unexpectedly, the C S group is not
    involved in intermolecular hydrogen bonding, as generally observed in
    homodisubstituted thioureas. Instead, molecules form a one-dimensional
    network based on weak N-H center dot center dot center dot O
    (heterocycle) hydrogen bonding, resulting in a zigzag ribbon-like
    structure around the crystallographic 2(1) screw axis along [100].

    RISK BEHAVIORS; CONDOM USE; TRANSMITTED-DISEASES; SUBSTANCE-ABUSE
 AB Gender-based violence (GBV) is common in southern Africa. Here we use
    GBV to include sexual and non-sexual physical violence, emotional
    abuse, and forms of child sexual abuse. A sizeable literature now links
    GBV and HIV infection. Sexual violence can lead to HIV infection
    directly, as trauma increases the risk of transmission. More
    importantly, GBV increases HIV risk indirectly. Victims of childhood
    sexual abuse are more likely to be HIV positive, and to have high risk
    behaviours. GBV perpetrators are at risk of HIV infection, as their
    victims have often been victimised before and have a high risk of
    infection. Including perpetrators and victims, perhaps one third of the
    Southern African population is involved in the GBV-HIV dynamic. A
    randomised controlled trial of income enhancement and gender training
    reduced GBV and HIV risk behaviours, and a trial of a learning
    programme reported a nonsignificant reduction in HIV incidence and
    reduction of male risk behaviours (primary prevention). Interventions
    among survivors of GBV can reduce their HIV risk (secondary
    prevention). Various strategies can reduce spread of HIV from infected
    GBV survivors (tertiary prevention). Dealing with GBV Could have an
    important effect on the HIV epidemic. A policy shift is necessary. HIV
    prevention policy should recognise the direct and indirect implications
    of GBV for HIV prevention, the importance of perpetrator dynamics, and
    that reduction of GBV should be part of HIV prevention programmes.
    Effective interventions are likely to include a structural component,
    and a GBV awareness component. (c) 2008 Wolters Kluwer Health vertical

 AB Programmed cell death is a fundamental requirement for embryogenesis,
    organ metamorphosis, and tissue homeostasis. Since the vast majority of
    cytotoxic modalities exert their anti-tumor effects by induction of
    apoptosis, programmed cell death has emerged as a potential target for
    cancer treatment at various stages of tumor progression.
    Immuno-regulation and chemoradiosensitization are potential. pathways
    where insight in apoptotic mechanisms may lead to improvement of
    chemoradiotherapeutic modalities. The central mediator of the intrinsic
    pathway of apoptosis is the mitochondrion, in which changes of the
    outer membrane's permeability cause an outflow of cytochrome c and more
    than 40 molecules involved in apoptosis. These include Smac/DIABLO,
    Omi/HTR A2, endonuclease G, and apoptosis inducing factor (AIF). AIF, a
    57 kDa mitochondrial oxidoreductase, is released into the cytoplasm and
    translocates to the nucleus to induce cell death in response to
    poly-(ADP-ribose) polymerase-1 activation, resulting is DNA
    fragmentation independent of caspase activation. As a
    caspase-independent mechanism of apoptosis, AIF may be a potential
    target for chemoradiotherapeutic intervention in a number of
    malignancies. The aim of this review is to provide the available
    evidence of the role AIF in several malignancies with a particular
    emphasis in colon carcinogenesis. (C) 2009 Elsevier Inc. All rights

 AB U-Pb detrital zircon studies in the Rio Fuerte Group, NW Mexico,
    establish its depositional tectonic setting and its exotic nature in
    relation to the North American craton. Two metasedimentary samples of
    the Rio Fuerte Formation yield major age clusters at 453-508 Ma,
    547-579 Ma, 726-606 Ma, and sparse quantities of older zircons. The
    cumulative age plots are quite different from those arising from lower
    Paleozoic miogeoclinal rocks of southwestern North America and of
    Cordilleran Paleozoic exotic terranes such as Golconda and Robert
    Mountains. The relative age-probability plots are similar to some
    reported from the Mixteco terrane in southern Mexico and from some
    lower Paleozoic Gondwanan sequences, but they differ from those in the
    Gondwanan-affinity Oaxaca terrane. Major zircon age clusters indicate
    deposition in an intraoceanic basin located between a Late Ordovician
    magmatic arc and either a peri-Gondwanan terrane or northern
    Gondwanaland. The U-Pb magmatic ages of 151 3 Ma from a granitic pluton
    and 155 +/- 4 Ma from a granitic sill permit a revision of the
    stratigraphic and tectonic evolution of the Rio Fuerte Group. A
    regional metamorphism event predating the Late Jurassic magmatism is
    preliminarily ascribed to the Late Permian amalgamation of Laurentia
    and Gondwana. The Late Jurassic magmatism, deformation, and regional
    metamorphism are related to the Nevadan Orogeny. (C) 2008 Elsevier Ltd.

 AB A systematic review of published articles was performed to identify
    risk factors associated with recent transmission of tuberculosis (TB).
    The computerized search identified studies in PubMed, Ovid, CDSR,
    CINAHL and EMBASE published between 1994 and 2005. Of 137 articles, 30
    satisfied all the inclusion criteria for meta-analysis. A random
    effects model estimated the odds ratio (OR), confidence interval (CI),
    and heterogeneity between studies. Recent transmission of TB was
    associated with: ethnic minority (OR 3.03, 95%CI 2.21-4.16), being a
    native of the country (OR 2.33, 95%CI 1.76-3.08), residing in an urban
    area (OR 1.52, 95%CI 1.35-1.72), drug use (OR 3.01, 95%CI 2.14-4.22),
    excessive alcohol consumption (OR 2.27, 95%CI 1.69-3.06), homelessness
    (OR 2.87, 95%CI 2.04-4.02), previous incarceration (OR 2.21, 95%CI
    1.71-2.86), human immunodeficiency virus infection/acquired
    immune-deficiency syndrome (OR 1.66, 95%CI 1.36-2.05), young age (OR
    2.09, 95%CI 1.69-2.59), sputum smear positivity (OR 1.39, 95%CI
    1.20-1.60) and male sex (OR 1.37, 95%CI 1.19-1.58). The results should
    be useful for improving prevention and control strategies, thus
    contributing to a reduction in Mycobacterium tuberculosis transmission.

 AB The sandstone of the Galeana Sandstone Member of Taraises Formation
    have been interpreted as an extended delta deposit, which had its
    origin from the Coahuila Block, and few authors have proposed that the
    source area could be associated with the Tamaulipas Archipielago. The
    present study documents the sedimentological characteristics of the
    Galeana Sandstone Member, and on the basis of facies analysis and
    paleocurrent data, the sedimentary environments, and its depositional
    evolution were determined. The sandstone of the Galeana Sandstone
    Member show seven facies associations which are interpreted as tidal
    flat, prodelta, tidal-dominated delta front, deltaic barred months,
    sublittoral and subaqueous chine deposits. The tidal flat deposits are
    characterized by thinning-upward sequences, and they contain
    herringbone cross-bedding, lenticular and flaser bedding, as well as
    trace fossils of the genus Skolithos Thalassinoides Diplocraterion and
    Rhizocorallium. The deltaic system, deltaic barred mouth, and
    sublittoral deposits are characterized by interbedded sandstone and
    shale that show thickening-upward and thinning-upward sequences, as
    well as scarce sedimentary structures such as parallel lamination,
    normal graded beds, lenticular stratification, herringbone
    cross-bedding, and Macaronichnus trace fossils. The subaqueous dune
    deposits show, chaotic sequences with cross-bedding generated by dunes
    migration, reactivation surfaces, and ichnofossils of the genus
    Thalassinoides.
    The field data, such as paleocurrent and stratigraphic relationships
    suggest that: (i) sandstone of the Galeana Sandstone Member had a
    source circa located to the east of Potrero Prieto locality, which
    could be the Tamaulipas Archipielago, and (ii) the depocenter is
    located in the Galeana area, as indicated by the observed changes in
    bed thicknesses and the presence of an angular disconformity.

 AB Husk tomato is a Solanaceous plant from Mexico, this plant can grow
    wild or cultivated. In vitro propagation is an alternative for mass
    production of pathogen free plants. But some times acclimatization has
    been the limiting factor to reach this objective. Few reports related
    with husk tomato micropropagation are found, and this is the first one
    known to us where the changes on stomatal density and water potential
    of plantlets obtained from apical meristems, during the
    acclimatization, are evaluated. Plants of 30 days old with similar size
    were placed in individual hydroponics system, during seven weeks, all
    of them with plastic covers, which were gradually opened each seven
    days. Each time, the temperature and relative humidity were measured,
    in the acclimatization system and the growth chamber, for water
    potential estimation. At the sixth week, the water potential in the
    acclimatization system was close to that of the growth chamber (-107.8
    and -102.2 +/- 4.91 respectively). On the other hand, the stomatal
    density was evaluated at 15, 30 and 45 days of the acclimatization
    stage. Significant differences were observed at this parameter between
    adaxial and abaxial leaves surfaces, and between different plant ages.
    When both, water potential and stomatal density data were compared, a
    great correlation was observed. A 100% of the plants survived the
    acclimatization period.

 AB One of the substrates used to reproduce Trichoderma spp., is the
    relatively high cost whole rice grain. In order to find an organic,
    economical and available substrate for the region, in which this fungus
    could have a good development and a high viable spores production, this
    research was established, with the objective to evaluate 15 organic
    substrates for T. harzianum massive reproduction and spores viability,
    and to associate it with the nutrimental composition of the evaluated
    substrates. Husk tomato (flower calyx); rice (flower glumes, lemma and
    palea); garlic (coriaceous cataphyllary); cocoa (seed coat); sesame
    (fruit pericarp); peanut (fruit pericarp); coffee (fruit pericarp);
    bean sheath (fruit pericarp); corn cob (feminine inflorescence rachis);
    rice, sorghum, bird seed and corn grains; soybean and corn stubble were
    evaluated. A completely randomized design with eight replications was
    used. Spore number and viability percentage was quantified and it was
    correlated with the proximal chemical analysis. The corn cob was the
    best substrate for the T. harzianum production and spore germination
    with 4.43 x 10(8) ml(-1) and 99.0% viability. Based on the proximal
    chemical analysis, the mycelium development, esporulation and spores
    viability, T harzianum has a good production in those organic
    substrates that have high humidity percentage, low mineral, protein and
    fat content, and an intermediate fiber percentage.

 AB Objective. We sought to test methods for generating epidemiological
    evidence on health conditions of small, dispersed minority communities.
    Methods. We used community-based mixed methods including a
    cross-sectional survey in 5 purposely selected settlements of Khorakane
    Roma (Gypsies of Muslim culture) in Italy to study the living
    conditions and health status of children aged from birth to 5 years.
    Results. In the 15 days prior to the survey, 32% of the children had
    suffered diarrhea and 55% had had a cough. Some 17% had experienced
    respiratory difficulties during the past year. Risk factors associated
    with these outcomes included years spent living at the camp,
    overcrowding, housing conditions, use of wood-burning stoves, presence
    of rats, and issues related to quality of sanitation and drains.
    Qualitative information helped define the approach and the design, and
    in the interpretation and consolidation of quantitative results.
    Conclusions. Guided by the priorities expressed by dispersed minority
    communities, small studies with little resources can provide a solid
    base to advocate for evidence-based participatory planning. Exact
    intervals appeared to be robust and conservative enough compared with
    other intervals, conferring solidity to the results. (Am J Public

 AB In this paper we obtain some practical criteria to bound the
    multiplication operator in Sobolev spaces with respect to measures in
    curves. As a consequence of these results, we characterize the weighted
    Sobolev spaces with bounded multiplication operator, for a large class
    of weights. To have bounded multiplication operator has important
    consequences in Approximation Theory: it implies the uniform bound of
    the zeros of the corresponding Sobolev orthogonal polynomials, and this
    fact allows to obtain the asymptotic behavior of Sobolev orthogonal
    polynomials. We also obtain some non-trivial results about these
    Sobolev spaces with respect to measures; in particular, we prove a main
    result in the theory: they are Banach spaces.

 AB To investigate the genotype and allele frequency of vascular
    endothelial growth factor gene polymorphisms in knee osteoarthritis
    (OA) and their relationship with disease activity and lipid profile, we
    enrolled 49 knee OA patients and 75 healthy subjects (HS) as a control
    group. Body mass index (BMI), laboratorial assessment and genotyped by
    polymerase chain reaction-restriction fragment length polymorphisms
    (PCR-RFLP) were studied in both groups. Disease activity was determined
    using Lequesne and WOMAC indexes; a P value < 0.05 was considered
    significant. The -460 and +405 VEGF polymorphisms did not shown
    significant association between OA patients and HS. However, between OA
    patients and HS a significant differences were observed in BMI, age,
    apo A-I and apo B, independently of both polymorphisms studied (P <
    0.05). In conclusion, increased apo A-1 and apo B levels are associated
    in knee OA, but the -460 T/C and +405 C/G VEGF polymorphisms are not
    associated with knee OA susceptibility.

 AB Ethyl 4 '-n-undecyloxybiphenyl-4-carboxylate, 2(11)OBC, and 4
    '-n-undecyloxybiphenyl-4-carboxylic acid, (11)OBC, are smectic liquid
    crystals precursors of low molecular weight premesogens, and of
    potential liquid crystal macromolecules. The single-crystal X-ray study
    of 2(11)OBC showed that it crystallizes in a non-centrosymmetric space
    group with molecules stacked along the short axis [010] and [001]
    without significant pi center dot center dot center dot pi or CH center
    dot center dot center dot pi interactions. Such an arrangement may
    explain its strong tendency to form smectic mesophases. Both biphenyl
    derivatives have a rich polymesomorphism whose phase sequences were
    determined by DSC, optical microscopy and diffraction profiles using
    synchrotron radiation. These profiles indicated quite similar phase
    transitions in the two samples, although very different transition
    temperatures. Thus, the phase transitions (on cooling) of 2(11)OBC are:
    Isotropic -> SmA (101 degrees C)-> SmB (88 degrees C)-> SE (79 degrees
    C)-> crystal phase (43 degrees C), while those (on cooling) of (11)OBC
    are the following: Isotropic -> SmA (246 degrees C)-> SmB (192 degrees
    C)-> SX (162 degrees C)-> SE (148 degrees C)-> crystal phase (62
    degrees C). The much higher transition temperatures for the acid
    derivative are explained by considering that this molecule forms dimers
    through classical O-H center dot center dot center dot O hydrogen bonds
    involving the carboxylic groups.

 AB The title compound, [Cu-2(C16H20N6O4)(NO3)(2)(H2O)(4)] center dot
    3H(2)O, crystallizes with two dinuclear Cu-II complex molecules, each
    lying on an inversion center, and six solvent water molecules per unit
    cell. The central 1,6-diazecine ring adopts the common chair
    conformation invariably found in the family of complexes bearing such
    ligands. The Cu-II atoms have an octahedral geometry, with a very
    strong tetragonal distortion due to the Jahn-Teller effect. Axial sites
    are occupied by a nitrate ion and a water molecule. The Cu center dot
    center dot center dot Cu separations [7.3580 (9) and 7.3341 (9)
    angstrom] are compatible with a potential catecholase activity.
    Neighboring molecules in the crystal structure are connected via O-H
    center dot center dot center dot O hydrogen bonds formed by water
    molecules and carboxylate O atoms. N-H center dot center dot center dot
    O hydrogen bonds are also present.

 AB The spiny lobster P. inflatus is a fishing resource of regional
    economic importance ill Guerrero, Mexican Tropical Pacific coast where
    this lobster has not been Studied enough. This analysis of the captures
    in Guerrero's coasts will contribute to a better managing of this
    fishery. We studied the size distribution Of the Capture, the
    percentages of reproductive females and the size class by climatic
    season, as well as the size of sexual Maturity in 2569 lobsters
    collected from June 2004 to July 2005 in three zones in the Guerrero's
    coastal region: Copala, Zihuatanejo and Acapulco. The size composition
    and the size contributing with major number of lobsters to this
    commercial catch differed among the study sites. The wider range and
    the bigger sizes were obtained in Acapulco followed by Zihuatanejo and,
    finally, by Copala. There were no significant differences for the
    percentages of reproductive females among between stations in the three
    places (chi(2), P > 0.05) and the reproductive females (with
    spermatophores and/or ovigerous mass) grouped by size class, in general
    presented maximums in Summer and autumn exempting the Sizes under 50 mm
    LC and the ones over 80 mm LC. Size at first sexual maturity in P.
    inflatus was 57.4 mm LC at Copala, 63.6 mm LC at Zihuatanejo and 68.6
    mm LC at Acapulco. The results indicate the necessity to manage the
    resource taking into account the differences among capture areas.

 ID BROADENING CONCEPT; ORIENTATION; ADVANTAGE
 AB Goals pursued in this working paper include a synthetic and reflexive
    study about the historical evolution of the concept of marketing,
    identifying the most important contributions and their respective
    Promoters. For this study, three clearly differentiated periods have
    been identified: the pre-conceptual period (1900-1959), the formal
    conceptualization period (1960-1989) and the current period of
    marketing concept (1990 - 2005). The topic is covered from the first
    "baby steps" of marketing as a discipline more oriented focused on the
    economy, passing through the significant contributions and birth of a
    genuine scientific community led by the American Marketing Association,
    examining the influence of the famous ICTs (information and
    Communication Technologies) on a concept called e-marketing and on the
    other hand, the concept of holistic marketing.

 AB By means of the GLM procedure of the SAS statistical package, the
    effects of the genetic groups (GG) Boer x local (BL), Nubian x local
    (NL) and local x local (LL) kids, sex of kid (SK), type of birth (TB),
    age of dam (AD), season (SB) and year (YB) of birth, as well as
    genotype x environment interactions on birth weight (BW), adjusted
    weaning weight (AWW) and adjusted yearling weight (AYW) were evaluated.
    Likewise, the effect of GG on slaughter weight (SW), chilled carcass
    weight (CW) and dressing percentage (DP) was evaluated in a sample of
    kids of each genotype. Overall least-squares means for BW, AWW, AYW,
    SW, CW and DID were 3.3 +/- 0.5 kg, 14.4 +/- 1.8 kg, 26.6 +/- 2.5 kg,
    26.1 +/- 4.6 kg, 11.1 +/- 2.1 kg, and 42.3 +/- 3.3%, respectively.
    Generally, the effects of GG, SK, TB, SB, YB, as well as some genotype
    x environment interactions influenced (P < 0.05) the variation of BW,
    AWW and AYW. Regarding the carcasses, an effect of GG on SW and CW was
    found (P < 0.05). In general, the BL kids had the highest averages for
    all of the traits analyzed, followed by the NL kids, and finally by the
    LL kids.

 AB Introduction: Erlotinib, a tyrosine kinase inhibitor, has improved
    survival and quality of life in patients with non-small cell lung
    cancer (NSCLC) after first- or second-line chemotherapy. Asian Origin,
    adenocarcinoma histology, female gender, lack of tobacco use, and
    expression of epidermal growth factor receptor are significant
    independent predictors of response to Erlotinib. Although tobacco Use
    is considered a major cause of NSCLC. other risk factors such as
    wood-smoke exposure (WSE) are associated. Almost 3 billion people
    worldwide rely oil solid fuels Lis their primary source of domestic
    energy for cooking and heating.
    Methods: In this Study, 150 consecutive unselected patients with
    histologically proven NSCLC with progression after prior first- or
    second-line chemotherapy and/or poor performance status were treated
    with Erlotinib 150 mg/d. Clinical and pathologic characteristics were
    associated with response.
    Results: Overall response to Erlotinib was observed in 51 patients
    [34%; 95% confidence interval {95%, CI}, 29.9-37.6]. In multivariate
    analysis, clinical features associated with response to Erlotinib were
    adenocarcinoma (35 versus 20%; p=0.05) and WSE (83 versus 13%; p <
    0.001). Factors associated with longer progression-free survival ill
    COX analysis included adenocarcinoma (7.9 versus 2.3 months; p =
    0.009), female gender (8.4 versus 5.3 months; p=0.04), and WSE (17.6
    versus 5.3 months; p = 0.006).
    Conclusions: WSE is associated with better response to Erlotinib and
    improved progression-free survival in patients with NSCLC. Additional
    studies in epidermal growth factor receptor signaling pathway in
    WSE-associated NSCLC are warranted.

 AB Objective: Demonstrate the effective use of community-based evidence
    for health promotion by Lady Health Workers (LHWs) in Sindh, Pakistan.
    Methods: A baseline study on mothers and children provided local
    evidence for risk communication tools designed and tested by LHWs. The
    communities were randomized to intervention and control. LHWs visited
    women before and after childbirth to discuss safe practices in
    pregnancy, in the intervention group LHW using the new tools and in the
    control group using their standard procedures. A household survey and
    focus groups permitted assessment of the impact of the intervention.
    Results: Women in the intervention communities were more likely to
    attend prenatal checkups, to stop routine heavy work during pregnancy,
    to give colostrum to newborn babies, and to maintain exclusive
    breastfeeding for four months. Community focus groups confirmed a
    positive reaction to the tools.
    Conclusion: Discussion by lay health workers of local evidence
    underlying safe motherhood messages improved uptake of protective
    health practices.
    Practice implications: Door-to-door health promotion based on
    culturally appropriate interaction around relevant evidence can have a
    positive impact on health practices. Engaging health workers from the
    onset builds capacities, improves dialogue within the health system and
    performance of frontline health workers. (c) 2008 Elsevier Ireland Ltd.

 DE Zea mays; normal and high quality protein of grain; specific and
    general combining ability
 AB Association among agronomic field traits and physiological seed quality
    and their genetic components are important factors for broadening
    germoplasm characterization in a plant breeding program. This research
    analyzed the general (GCA) and specific (SCA) combining abilities
    effects and the genetic action type of agronomic traits and
    physiological quality of normal and high quality protein seed in maize
    (Zea mays L.). The genetic material was a group of 14 maize inbred
    lines, seven of normal grain and seven of high protein quality. The
    agronomics traits analyzed were: male and female flowering, plant and
    ear height, plant and ear visual score and grain yield. Physiological
    quality was determined by initial and final standard germination,
    initial and final plumule length, and final dry weight. Results showed
    significative variation among genotypes (P :5 0.05) for GCA and SCA
    effects in all traits. Crosses B-41 x CML-144, CML-144 x CLQ-6203 and
    LT-154 x CML-177 outstanded by their highest grain yield with 1.39,
    1.37 and 1.19 t ha(-1) respectively, while crosses T-45 x CLQ-6203,
    T-37 x CML-141 and LT-154 x CML-177 had the highest SCA values in final
    standard germination, with 23.2, 22.9 and 14.2 % respectively. Lines
    T-45, T-44 and LT-155 showed the highest GCA values for grain yield,
    with 0.41, 0.78 y 0.45 t ha(-1), while lines CML-144 and LT-155 showed
    the highest GCA values for final standard germination with 6 % in both
    cases. The predominating genetic action type was additive for all of
    the agronomic and physiological traits.

 DE Annona diversifolia Saff.; respiratory intensity; fruit weight;
    ethylene production; soluble solids; vitamin C
 AB In Mexico ilama fruit (Annona diversifolia Saff.) is normally sold with
    cracks at the base of the peduncle and without it. Consequently, it has
    a short shelf life and is more susceptible to rot. This study evaluates
    the biochemical, biophysical and physiological changes during
    development of white and pink pulped ilama fruit to determine its
    growth and maturation pattern on the plant. Open flowers on 30 trees
    (15 white pulp and 15 pink pulp) located in San Lorenzo, Municipality
    of Ajuchitlan, Guerrero, Mexico, were tagged. Samples were taken at
    different fruit growth stages to record total fruit weight, proportion
    of pulp and peel, respiratory intensity, ethylene production, total and
    reducing sugars, total soluble solids (degrees Bx), and vitamin C
    content. Both types of fruit (white and pink pulp) had a double sigmoid
    growth pattern with a period of total development of 99 d after
    flowering (DAF). The slow fruit growth phase coincided with a decrease
    in respiratory intensity; ethylene production was not detected until 99
    DAF, when maximum accumulation of total and reducing sugars and degrees
    Bx were recorded. However, both types of fruits initiated a significant
    increase in total and reducing sugars and degrees Bx as of 85 DAF,
    indicating the beginning of the ripening process.

 DE dual-purpose cows; Saccharina; supplements
 ID FERMENTATION
 AB An experiment was conducted to know the intake and the milk yield of
    dual-purpose cows (American Brown Swiss and F1 Bos taurus x Bos
    indicus; n=28), with weight, age and lactation days of 430 +/- 54 kg, 7
    +/- 2 years, and 122 +/- 26 d, respectively. The animals were
    supplemented with Saccharina, elaborated with burnt and non-burnt
    sugarcane stalks, plus protein concentrate. The cows grazed on star
    grass. Later, according to the different treatments, complementary
    fodder was supplied individually: T1 = grazing + fresh integral
    sugarcane, with 1.5% of urea + 2 kg in fresh basis of commercial
    concentrate; T2 = grazing + traditional Saccharina, mixed with 20 % of
    the commercial concentrate + 1 kg of commercial concentrate; T3 =
    grazing + Saccharina elaborated with burnt stalks, inoculated with 15 %
    of traditional Saccharina + 2 kg of commercial concentrate; T4 =
    grazing + traditional Saccharina + 2 kg of commercial concentrate. The
    study was performed according to a complete random design, and the
    initial milk production was used as covariable. The cows supplemented
    with fresh integral sugarcane and Saccharine with burnt stalks had
    higher intake (P < 0.05) than those supplemented with traditional
    Saccharina (5.24 and 4.52 vs 2.93 kg of DM cow(-1)d(-1)). However, the
    total intake (17.59, 14.94, 16.84 and 17.16 kg of DM cow(-1) d(-1)) and
    the milk yield (8.47, 8.17, 7.72, and 8.04 kg cow(-1) d(-1)) did not
    differ between themselves. The burnt sugarcane may be used as substrate
    to elaborate Saccharina for the intake of dual-purpose cows.

 AB Background Previous studies have reported elevated levels of C-reactive
    protein (CRP) in obese and diabetic subjects, but it is unclear whether
    both these conditions have an additive effect on the variability of
    serum CRP levels.
    Methods and Results The study enrolled 385 men and women who were
    classified into 4 groups: (1) diabetes (n=97), (2) obesity (n=108), (3)
    diabetes/obesity (n=78), and (4) healthy (n=102). All were Mexican
    subjects from Guerrero State. Serum high-sensitivity CRP (hs-CRP)
    levels were higher in both type 2 diabetes mellitus (T2DM)/obesity and
    obesity (5.1 mg/L) groups than in the diabetics (1.8 mg/L) without
    obesity. Only the measurements of obesity were strongly related to
    hs-CRP (body mass index, r=0.46 and waist circumference, r=0.41). The
    presence of T2DM and obesity explain 20% of the circulating hs-CRP
    level, following waist circumference (16%), leukocyte count (10%),
    diastolic blood pressure (6%), and female gender (4%). Obese subjects
    (odds ratio (OR)=6.3) and T2DM/obesity patients (OR=6.9) showed high
    risk for coronary disease and this effect was increased in T2DM/obesity
    women (OR=9.9). Also, abdominal obesity was associated with high
    coronary disease risk (OR=5.4), showing an increase in women (OR=7.3).
    Conclusion High hs-CRP levels are related to obesity and central
    distribution of body fat, leading to a higher cardiovascular risk among
    Mexican subjects.

 AB The structure of the title solvate, C9H6O6 center dot C2H6OS, was
    determined 30 years ago [Herbstein, Kapon & Wasserman (1978). Acta
    Cryst. B34, 1613-1617], with data collected at room temperature, and
    refined in the space group P2(1). The present redetermination, based on
    high-resolution diffraction data, shows that the actual space group is
    more likely to be P2(1)/m. The crystal structure contains layers of
    trimesic acid molecules lying on mirror planes. A mirror plane also
    passes through the S and O atoms of the solvent molecule. The molecules
    in each layer are interconnected through strong O-H center dot center
    dot center dot O hydrogen bonds, forming a two-dimensional
    supramolecular network within each layer. The donor groups are the
    hydroxyls of the trimesic acid molecules, while the acceptors are the
    carbonyl or the sulfoxide O atoms.

 TI A community-based impact assessment of the Wild Coast Spatial
    Development Initiative, 1997-2004
 SO DEVELOPMENT SOUTHERN AFRICA
 LA English
 DT Article
 ID SOUTH-AFRICA; GROWTH
 AB Much of the debate around the spatial development initiatives (SDIs) in
    South Africa is based on economic theory. To add the community
    perspective, an evaluation of local economic development on the Wild
    Coast followed a baseline in 1997 with comparable surveys in 2000 and
    2004. Apart from an increase in access to piped water and a reduction
    in unofficial payments for health services, there was little community
    evidence of development over this period. Residents reported decreasing
    knowledge of the SDI and there was no increase in numbers considering
    small business ownership. In the investment-intensive 'anchor' areas,
    as in the SDI as a whole, there was no significant increase in
    employment and more households received remitted incomes from migrant
    workers. In an SDI for small businesses in tourism and agriculture,
    there was a dramatic fall off in food production. No more households
    had loans in 2004 than in 1997, but more were taking loans from loan
    sharks. Other spatial planning initiatives might learn from the Wild
    Coast, not least through the perspectives gained from community-based
    impact assessments.

 AB Atherosclerosis is a multifactor disease. Lately, infectious factors
    such as C. pneumoniae have been found to be involved. To determine
    whether the infection by C. pneumoniae is a risk factor for
    atherosclerosis in patients with AIDS. Case-control study on 43
    patients with AIDS under HAART (16 cases and 27 controls). To document
    atherosclerosis, a carotid and transcranial Doppler ultrasound was
    performed. Anti-C pneumoniae antibodies were searched using a
    micro-immunofluorescence test for IgM and IgG levels. To study the
    associations with risk of atherosclerosis, Odds Ratios were calculated
    for each IgG anti-C. pneumoniae antibody titre. A titre of 1: 64
    significantly increased the risk of atherosclerosis. These results
    suggest that hypertriglyceridemia and C. pneumoniae infection
    coexistence significantly increases the risk of atherosclerosis. The
    inverse geometric average of the antibodies titre against C. pneumoniae
    in individuals with atheromatous plaque fell to 64, two titres above
    the controls. This difference turned out to be statistically
    significant. Exposure to C. pneumoniae with antibodies (IgG) should be
    considered in any HIV diagnosed patient as a risk factor for
    atherosclerosis, having found that the inverse geometric averages of
    antibodies titre are significantly different comparing cases and
    controls, especially in patients with dyslipidemia,
    hypertriglyceridemia or in patients whose treatments could cause these
    conditions. In patients with concomitant hypertriglyceridemia, the
    association increases up to three times. It is advisable that AIDS
    patients take a serological test to determine exposure to C.
    pneumoniae, and to assess treatment options.

 AB The title compound, C27H39N3O2 center dot H2O, is a chiral
    pyridine-2,6-dicarboxamide derivative including cis-myrtanyl groups as
    amine substituents. The pyridine-2,6-dicarboxamide core approximates
    C-2 point symmetry and a solvent water molecule lies on the
    pseudo-twofold axis. The water molecule serves both as acceptor and
    donor for efficient hydrogen bonds involving N-H and C=O functional
    groups as donor and acceptor groups, respectively. As a result, each
    water molecule in the crystal structure is tetrahedrally bonded to
    three symmetry-related molecules, forming a three-dimensional
    supramolecular network. Such an arrangement is a common feature found
    in the majority of X-ray-characterized symmetrically substituted
    pyridine-2,6-dicarboxamide derivatives.

 ID INCLUSION COMPOUND; STEREOCHEMISTRY
 AB The title compound, C20H30O3, is a new functionalized
    perhydrotriphenylene derivative formed via a tandem Michael
    addition-aldol reaction. The structural study reveals that the system
    of fused rings approximates a C-2 point symmetry, with trans-cis-cis
    ring junctions, while highly symmetric all-trans perhydrotriphenylene,
    previously characterized, approximates a D-3 symmetry. The
    perhydrotriphenylene nucleus of the title compound corresponds to the
    third stable stereoisomer isolated for this polycyclic system.
    Considering that the C-S isomer was obtained recently through a similar
    tandem reaction, a general strategy is proposed which may help to
    obtain other stable stereoisomers of perhydrotriphenylene.

 AB Temporal variation in the helminth parasite communities of the Pacific
    fat sleeper, Dormitator latifrons, from Tres Palos Lagoon, Guerrero,
    Mexico, was studied at the component community and infracommunity
    levels. In total, 185 host specimens were collected between April 2000
    and March 2001. Eight parasite species were identified: Clinostomum
    complanatum, Echinochasmus leopoldinae, Ascocotyle (Phagicola) longa,
    Pseudoacanthostomum panamense, Saccocoelioides sp., Parvitaenia
    cochlearii, Neoechinorhynchus golvani, and Contracaecum sp. The
    communities had low numbers of parasite species and diversity, and
    contained only generalist parasites. Nested (nonrandom) species
    composition was observed in the infracommunities during all climatic
    seasons. The variation in nestedness intensity was attributed to a
    process of sequential colonization by the most common parasite species,
    because some were more abundant in the dry season, and others were more
    abundant in the rainy season.

 AB Roselle is a shrub cultivated with the purpose of using the calyx of
    their flowers. However, the seeds are obtained as by-product and have a
    considerable economic potential owing their nutritive value and yield.
    The aim of this work was to describe the imbibition kinetics and
    moisture sorption isotherms at 25, 35 and 45 degrees C, of three
    Roselle seed cultivars produced in Mexico ("Criollo", "China" and
    "Sudan"). Results indicated that the imbibition process describes a
    curve that follows the Weibull distribution with a alpha coefficient of
    12.99, 8.81 and 2.21 hours and a beta coefficient of 0.83, 1.70 and
    0.72 for the Criollo, China, and Sudan cultivars, respectively. The GAB
    and the Chung-Pfost models describe appropriately the moisture sorption
    isotherms. Monolayer moisture content (a coefficient of GAB model) was
    3.97 to 5.71 d.b. which represents a water activity value ranging from
    0.1 to 0.30. Total isosteric heats of sorption, in the equilibrium
    moisture content region of 6 to 22% d.b., ranging from 52.85 to 42.90
    kJmol(-1), for the Criollo cultivar, 60.99 to 43.41 kJmol(-1), for the
    China cultivar and 51.23 to 43.20 kJmol(-1) for the Sudan cultivar. At
    equilibrium moisture content up to 12% d.b., total isosteric heat of
    sorption was similar to the vaporization enthalpy of water, but at a
    moisture content lower to 6% d.b. this variable reached the highest
    values.

 AB A scorpion prosoma, a plecopteran nymph, Euperlida parvicercifera
    Cifuentes-Ruiz gen. et sp. nov., and the elytra of an adult beetle
    (Coleoptera) are described from the Oligocene Coatzingo Formation,
    Puebla, Mexico. Specimens were found at the Los Ahuehuetes locality,
    Puebla, from where numerous plant remains have been previously
    described. A lacustrine paleoenviromnent for these sediments is
    confirmed based on habitat of recent Plecoptera. This report represents
    the first record of Oligocene continental arthropods from Central
    Mexico, and the first for a fossil Plecoptera in this country. It is
    the first record for a Nearctic extinct genus of Perlidae.

 AB In the title complex, [Pb(C9H11NO2)(2)(NO3)(H2O)(2)] NO3, the cation is
    a monomeric species including zwitterionic aminoacids. In both
    zwitterions, rotation of the NH3+ groups about their C-N bonds is
    blocked by intermolecular N-H center dot center dot center dot O
    hydrogen bonds. Assuming a limit for Pb-O bond lengths of 3 angstrom,
    the Pb-II ion is coordinated by eight O atoms. Each phenylalaninate
    ligand coordinates asymmetrically, with one short and one long Pb-O
    bond. Coordinated water molecules are also found at significantly
    different distances, while the bidentate nitrate ion coordinates
    symmetrically. The resulting [(PbO8)-O-II] core is hemi-directed, with
    a void placed almost trans to a carboxylate group. However, the 6s(2)
    lone pair of the metal center can not be considered as stereochemically
    active, as a non-coordinating O atom of a nitrate belonging to a
    symmetry-related cation is placed in the empty hemisphere, with a short
    Pb center dot center dot center dot O separation of 3.035(10) angstrom.

 AB Several polymorphisms have been described in the PAI-1 gene including
    the -844 G/A and Hind III C/G polymorphisms. These polymorphisms have
    been associated with different diseases such as preeclampsia and
    cardiovascular diseases. The allele and genotype frequencies of both
    PAI-1 polymorphism where investigated in Mexican subjects and compared
    with other healthy worldwide populations. The hematological and
    biochemical parameters where classified according each genotype. in our
    studied group. One hundred Mexican subjects were recruited. Demographic
    data and hematological and biochemical parameters were collected, and
    genomic DNA isolation was performed in all the participants. Screening
    of both polymorphisms studied was made by polymerase chain reaction and
    restriction analysis. Levels of plasminogen activator inhibitor-1 in
    plasma were measured by ELISARA plasminogen activator inhibitor antigen
    kit. The -844 and Hind III genotypes frequencies were as follows: 49%
    (G/G), 40% (G/A), 11% (A/A) and 50% (C/C, 44% (C/G), 6% (G/G),
    respectively. The wild-type genotypes (G/G and C/C were significantly
    higher with respect to the compared populations. In addition, a
    significant increase of apolipoprotein A I in the carriers of G/A -844
    and C/G Hind III genotypes was observed. However, when the plasma
    plasminogen activator inhibitor levels were analyzed with respect to
    each genotype and haplotype, no significant differences were found.

 SO ANNALS OF HEPATOLOGY

 AB Many hepatoprotective herbal preparations have been recommended in
    alternative systems of medicine for the treatment of hepatic disorders.
    No systematic study has been done on protective efficacy of
    Leucophyllum frutescens to treat hepatic diseases. Protective action of
    L. frutescens methanol extract (obtained by maceration) was evaluated
    in an animal model of hepatotoxicity induced by carbon tetrachloride
    (CCL4). Wistar albino rats were divided into five groups. Group I was
    normal control group; Groups ii-V received CCl4. After inducing hepatic
    damage, Group II served as control CCl4; Group III was given silymarin
    as reference hepatoprotective; and Groups IV and V received different
    doses of plant extract. Liver marker enzymes were assayed in serum.
    Samples of livers were observed under microscope for the
    histopathological changes. Levels of marker enzymes such as alanine
    aminotransferase (ALT) and aspartate aminotransferase (AST) were
    increased significantly in CCl4 treated rats (Group II). Groups TV and
    V intoxicated with CCl4 and treated with L. frutescens methanol extract
    significant decreased the activities of these two enzymes. Also these
    groups resulted in less pronounced destruction of the liver
    architecture, there is not fibrosis and have moderate inflammation
    compared with Group II. The present study scientifically validated the
    traditional use of L. frutescens for liver disorders. In conclusion the
    methanol extract of L. frutescens aerial parts could be an important
    source of hepatoprotective compounds.

 AB The title steroid, C29H46O4, is a furostene derivative with a C = C
    double-bond length of 1.353 (3) angstrom and an E configuration. The
    side chain is oriented toward the alpha face of the A-E steroidal
    nucleus and presents a disordered terminal CH2-OH group [occupancies
    for resolved sites are 0.591 (9) and 0.409 (9)]. The methyl group at
    C20 attached to ring E is also oriented toward the alpha face, avoiding
    steric hindrance with the carbonyl O atom of the acetyl group. The
    furostene and acetyl functionalities form an alpha, beta-unsaturated
    ketone system, with an s-cis configuration. All hydroxy and carbonyl
    groups are involved in weak intermolecular hydrogen bonds. The absolute
    configuration was assigned from the synthesis.

 AB In the course of the investigations into the fish parasites in the Tres
    Palos Lagoon in the State of Guerrero off the Pacific coast of Mexico,
    the following diplectanid species (Monogenoidea) from the gills of
    centropomids were found: Rhabdosynochus alterinstitus n. sp. from
    Centropomus nigrescens; Rhabdosynochus lituparvus n. sp.,
    Rhabdosynochus volucris n. sp., and Rhabdosynochus siliquaus n. sp.
    from Centropomus robalito (Centropomidae). The apparent synapomorphic
    character supporting a sister relationship of these diplectanids is a
    single, sheathlike accessory piece comprising 3 distal branches of the
    male copulatory organ. The origin of the present diplectanid on
    centropomids is discussed, and it is suggested that this may be the
    result of allopatric speciation as a result of the uplift of the
    Panamanian Isthmus, thereby separating the Pacific and Atlantic Oceans
    during Pleistocene (3-5 million yr ago).

 AB Objective. To identify the factors associated with dyspareunia, during
    the 60-180 days following childbirth, in women with a history of one or
    two childbirths.
    Methods. A case study of 304 women, matched by age and parity who
    visited family planning services in a hospital in Acapulco, State of
    Guerrero, Mexico, 60-180 days after giving birth. A questionnaire was
    administered to assess socioeconomic status (age, level of education,
    partner's level of education, marital status, employment, social
    security, and homeownership), obstetric history (type of birth, parity,
    location of the birth, tearing, episiotomy, and complications), and
    gynecological status (constricted introitus, scar tissue at the
    episiotomy site, symptoms of vaginitis, vaginal dryness, contraceptive
    use, and breast feeding duration). Cases were defined as those women
    who related pain, burning, or bleeding following vaginal intercourse
    after childbirth. An unconditional logistic regression model was
    applied and odd ratios (OR) and 95% confidence interval were calculated.
    Results. Of the 368 women who had reinitiated sexual relations, 152
    (41.3%) mentioned dyspareunia. The factors associated with dyspareunia
    were: an infection with or without episiorrhaphy dehiscence (OR =
    34.09; CI95%: 10.59-109.78); symptoms of vaginitis (OR = 7.43; CI95%:
    3.68-14.99); tightness in the introitus of the vagina (OR = 6.38;
    CI95%: 2.92-13.94), and breast feeding exclusively (OR = 4.86; CI95%:
    2.44-9.69).
    Conclusions. Dyspareunia was related to complications with episiotomy
    and its possible sequelae, such as infection, episiorrhaphy dehiscence,
    and constricted introitus. More attention should be given to the
    episiotomy site during the postpartum period and greater selectivity is
    needed when deciding which women require an episiotomy.

 AB Background: Cross-country comparisons of unofficial payments in the
    health sector are sparse. In 2002 we conducted a social audit of the
    health sector of the three Baltic States.
    Methods: Some 10,320 household interviews from a stratified,
    last-stage-random, sample of 30 clusters per country, together with
    institutional reviews, produced preliminary results. Separate focus
    groups of service users, nurses and doctors interpreted these findings.
    Stakeholder workshops in each country discussed the survey and focus
    group results.
    Results: Nearly one half of the respondents did not consider unofficial
    payments to health workers to be corruption, yet one half (Estonia 43%,
    Latvia 45%, Lithuania 64%) thought the level of corruption in
    government health services was high. Very few (Estonia 1%, Latvia 3%,
    Lithuania 8%) admitted to making unofficial payments in their last
    contact with the services. Around 14% of household members across the
    three countries gave gifts in their last contact with government
    services.
    Conclusion: This social audit allowed comparison of perceptions,
    attitudes and experience regarding unofficial payments in the health
    services of the three Baltic States. Estonia showed least corruption.
    Latvia was in the middle. Lithuania evidenced the most unofficial
    payments, the greatest mistrust towards the system. These findings can
    serve as a baseline for interventions, and to compare each country's
    approach to health service reform in relation to unofficial payments.

 AB Tuberculosis (TB) kills about 3 million people per year worldwide.
    Furthermore, TB is an infectious disease associated with HIV patients,
    and there is a rise in multidrug-resistant TB (MDR-TB) cases around the
    world. There is a need for new anti-TB agents. The study evaluated the
    antimycobacterial activity of nine plants used in Mexican traditional
    medicine to treat tuberculosis and other respiratory diseases.
    Nasturtium officinale showed the best activity (MIC = 100 mu g/mL)
    against the sensitive Mycobacterium tuberculosis. The following plants
    were active also but at 200 mu g/mL: Citrus sinensis, Citrus
    aurantifolia, Foeniculum vulgare, Larrea tridentata, Musa acuminata and
    Olea europaea. Contrary to the above data, activity against
    drug-resistant variants of M. tuberculosis was more evident, e.g. N.
    officinale was the most potent (MIC <= 100 mu g/mL) against the four
    mono-resistant variants tested; F. vulgare and O. europaea were active
    against all the resistant variants (MICs <= 100 mu g/mL). The most
    susceptible variant was the isoniazid resistant, being inhibited by C.
    aurantifolia, C. sinensis and O. europaea (MIC = 25 mu g/mL). These
    data point to the importance of biological testing of extracts against
    drug-resistant M. tuberculosis isolates, and the bioguided assay of
    these extracts for the identification of lead compounds against MDR-TB
    isolates. Copyright (c) 2007 John Wiley & Sons, Ltd.

 AB We assessed whether the -844 G/A polymorphism and mRNA expression of
    plasminogen activator inhibitor 1 (PAI-1) gene are associated with
    rheumatoid arthritis (RA). Demographic data, hematological, biochemical
    parameters, disease activity-disability indexes, -844 G/A genotypes and
    mRNA expression levels of the PAI-1 gene were determined in 50 RA
    patients and 50 healthy subjects (HS). Non-significant differences in
    genotype and allele frequencies related to -844 G/A polymorphism in RA
    versus HS, were found. High mRNA expression of the PAI-1 gene, was
    demonstrated in RA versus HS (P < 0.05). In addition, A/A genotype
    carriers showed increase of PAI-1 mRNA expression (3.1-fold) respect to
    G/G and G/A genotypes in RA patients (P < 0.05). Our finding suggest an
    association of A/A -844 PAI-1 genotype with high PAI-1 mRNA expression
    in RA patients.

 ID COMMUNITY; PURPLE; GOULD
 AB Plicopurpura patula pansa is a carnivore snail common of the Mexican
    Pacific rocky shores. Its hypobranchial gland produces a secretion
    that, in the presence of oxygen and sunlight, becomes purple. We
    determined the spatial distribution of the snail on beaches that differ
    in substratum, wave exposure, and the degree substratum's inclination.
    The average snail density was calculated. Using the Morisita index
    (I-d) and the Morisita standardized index (I-p), we found that in 96.3%
    of the samples taken, the snails were distributed according to a patchy
    distribution. The rest of the time, their distribution was random. The
    I index oscillated between 0.1522 and 0.5435. Smaller fluctuations of
    the I index were observed in 5 beaches with substrata that were more
    stable and had a larger number of cracks and crevices than those on
    beaches with mobile substrata, such as rolled rocks.

    Huber) in seed yield, was evaluated in Cocula, Gro. Seven distances
    between plants (30, 60, 90, 120, 150, 180 and 210 cm) were evaluated,
    in combination with two pruning levels (without and with pruning); the
    14 treatments were distributed in a randomized complete block design in
    a split plot arrangement with four replications. The treatments showed
    significant differences in plant size, number of fruits and seed
    weight. The best densities, 26 666 and 8 888 plants/ha (30 and 90 cm
    between plants) increased the quantity of fruits.

 AB Introduction Cancer during pregnancy is uncommon. However, recent
    trends in the prolongation of the childbearing age have made
    cancer-associated pregnancies more frequent. The objective of our study
    was to describe the frequency, types of cancer, and treatment with this
    association in our institution.
    Materials and methods The clinical records of 36 patients who presented
    to a regional reference center in Mexico over 10 years were reviewed
    collecting demographics, pregnancy characteristics and outcomes, type
    of cancer, clinical stage, treatment, and oncological outcome.
    Results The following tumors were observed: Uterine cervix (20), breast
    (7), ovary (3), non-Hodgkin Lymphoma (2), and other malignancies (4).
    The mean age of the patients was 30 (range 20-39) years. Mean follow up
    was 17.8 (range 1-74) months. The pregnancies were synchronous in 23
    cases and 13 were diagnosed in the following 12 months after birth.
    Mean gestational age of the product was of 37.4 weeks, resulting in 15
    deliveries with healthy products, four abortions and four deaths. The
    majority of patients had advanced clinical stages. Overall survival was
    36.4%.
    Discussion Cancer during pregnancy appears to have a worse outcome when
    compared to the results reported in the literature of non-pregnant
    women with the same conditions. This may be related to the advanced
    clinical stages we found. Cancer during pregnancy requires specialized
    attention to improve both fetal and maternal outcomes.

 AB In this paper, a simulated annealing algorithm is presented for the
    bandwidth minimization problem for graphs. This algorithm is based on
    three distinguished features including an original internal
    representation of solutions, a highly discriminating evaluation
    function and an effective neighborhood. The algorithm is evaluated on a
    set of 113 well-known benchmark instances of the literature and
    compared with several state-of-the-art algorithms, showing improvements
    of some previous best results. (C) 2006 Elsevier B.V. All rights

 AB BACKGROUND: Beans are rich and inexpensive sources of proteins and
    carbohydrates around the world, but particularly in developing
    countries. However, many legume varieties are still underutilized. In
    this study, physical characteristics of the seeds of three Phaseolus
    lunatus cultivars were characterized. Also, the chemical composition
    and starch digestibility in the cooked beans were assessed.
    RESULTS: 'Comba floja' variety exhibited the highest thousand-kernel
    weight whereas the lowest was found in 'comba violenta'. This agrees
    with seed dimensions: 'comba floja' had the Longest seeds (16.36 mm)
    and 'comba violenta' the shortest ones (13.98 mm). All samples
    exhibited high protein content, but levels in 'comba blanca' variety
    (216 g kg(-1)) were lower than the in other two cultivars. Total starch
    (370-380 g kg(-1)) and potentially available starch content (330-340 g
    kg(-1)) were similar in the three varieties. Resistant starch level in
    the cooked seeds ranged between 38 and 45 g kg(-1). Low enzymatic
    hydrolysis indices (HI) were recorded (30.2-35%), indicating a low
    digestion rate for Phaseolus lunatus starch. HI-based predicted
    glycemic indices ranged between 34% and 39%, which suggests a 'slow
    carbohydrate' feature for this legume.
    CONCLUSION: Phaseolus lunatus beans appear to be a good source of
    protein and slow-release carbohydrates with potential benefits for
    human health. (c) 2007 Society of Chemical Industry.

 AB An extensive survey of helminth parasites in fish species from Tres
    Palos Lagoon, in Guerrero, Mexico, resulted in identification of 39
    metazoan parasite species (37 helminth and 2 crustaceans) in 13 fish
    species (n = 1,498). Specimen collection in this coastal lagoon was
    done between April 2000 and November 2003. Digenean species (18, 8
    adult and 10 metacercariae) dominated the parasite fauna. The most
    widespread species of parasite were: Contracaecum sp. (Nematoda),
    Pseudoacanthostomum panamense, Austrodiplostomum compactum, Ascocotye
    (Phagicola) longa (Digenea), Neoechinorhynchus golvani
    (Acanthocephala), Ergasilus sp. (Copepoda), and Argulus sp.
    (Branchiura). Parasite fauna species composition exhibited a clear
    freshwater influence as 56.4% (22 of 39) of the identified species have
    a freshwater distribution in Mexico. For 32 of the parasite species,
    this report constitutes the first geographical host record for Tres
    Palos Lagoon, Guerrero, Mexico.

 AB We quarterly sampled the molluskan community of Playa Ventura,
    Guerrero, Mexico, Sample Size (20 m(2) in 1 m(2) units) was determined
    by the spatial distribution pattern of Plicopurpura pansa using a
    negative binomial distribution. The density of the P pansa was 5.19
    snails/m(2) and the sex ratio near 1: 1, The average size was 20.10 mm
    (most females were 10.5 to 27.0 mm most males 12.0 to 27.0 mm). Density
    was high and small sized dominated. Mean size varied with time. General
    mean weight was 1.79 g. Females weight varied more, maybe because of
    the reproductive cycle. Recruits were collected in five samplings. Most
    copulation activity was in March of 2001. The associated Community
    includes 26 species of Gastropoda. five of Bivalvia and one of
    Polyplacophora, Brachidontes semilaevis being dominant.

 AB The crystal structure of the title compound (common name:
    trans-azoxybenzene, t-AXB), C12H10N2O, was determined at 299 +/- 0.5 K,
    i.e. 6 K below its melting point. The azoxy group has the expected
    geometry, and the 0 atom is affected by libration normal to the N = N-O
    plane. The O atom is disordered over two positions; the site-occupancy
    ratio is similar to 3:2. Phenyl rings are out of the NNO plane, with
    dihedral angles ranging from 20 (1) to 34 (1)degrees. The dihedral
    angle between the two phenyl rings is 46.19 (11)degrees. This geometry
    contrasts strongly with the gas-phase conformation of t-AXB, previously
    determined by electron diffraction combined with ab initio
    calculations, which showed that the stable conformation is planar. This
    discrepancy is, however, consistent with low rotational barriers for
    phenyl rings. These features could be of interest in relation to the
    actual reaction mechanism of the Wallach rearrangement (acid-catalyzed
    isomerization of t-AXB into 4-hydroxyazobenzene), which remains a
    controversial matter.

 AB The title molecule, C19H23NO3, is an amphiphilic molecule with a
    hydrophobic alkyl chain and polar hydroxy groups. The molecule is
    almost planar, with a dihedral angle between the aromatic rings of 8.52
    ( 11)degrees. This conformation is, at least partially, a consequence
    of a strong intramolecular hydrogen bond between the imine N atom and
    the ortho OH functionality, resulting in an S( 6) ring. The molecules
    are associated in a layered network built via O-H center dot center dot

 AB Introduction Cancer during pregnancy is uncommon. However, recent
    trends in the prolongation of the childbearing age have made
    cancer-associated pregnancies more frequent. The objective of our study
    was to describe the frequency, types of cancer, and treatment with this
    association in our institution.
    Material and methods The clinical records of 36 patients, who presented
    to a regional reference center in Mexico over 10 years were reviewed
    collecting demographics, pregnancy characteristics and outcomes, type
    of cancer, clinical stage, treatment, and oncological outcome.
    Results The following tumors were observed: Uterine cervix (20), breast
    (7), ovary (3), non-Hodgkin Lymphoma (2), and other malignancies (4).
    The mean age of the patients was 30 (range 20-39) years. Mean follow up
    was 17.8 (range 1-74) months. The pregnancies were synchronous in 23
    cases and 13 were diagnosed in the following 12 months after birth.
    Mean gestational age of the product was of 37.4 weeks, resulting in 15
    deliveries with healthy products, four abortions, and four deaths. The
    majority of patients had advanced clinical stages. Overall survival was
    36.4%.
    Discussion Cancer during pregnancy appears to have a worse outcome when
    compared to the results reported in the literature of non-pregnant
    women with the same conditions. This may be related to the advanced
    clinical stages we found. Cancer during pregnancy requires specialized
    attention to improve both fetal and matemal outcomes.

    tectonic evolution of southwestern North America during the late
    Mesozoic

 AB Late Jurassic-Cretaceous arc-related volcaniclastic rocks from the
    southern Guerrero and western Mixteca terranes of Mexico were analyzed
    by U-Pb detrital zircon geochronology (laser
    ablation-multicollector-inductively coupled plasma-mass spectroscopy)
    to place constraints on the depositional history and provenance of the
    rocks. Pre-Middle Jurassic basement rocks and sandstone from the Upper
    Cretaceous Mexcala Formation were also analyzed to define the origin
    and provenance of the prevolcanic substratum, and the time of accretion
    of Guerrero composite terrane sequences.
    Data from the Taxco-Taxco Viejo, Teloloapan, and Arcelia assemblages
    indicate that the youngest (129-141 Ma) zircon fraction in each
    sequence was derived from local volcanic sources, whereas older
    populations (ca. 247-317, 365-459, 530-617, 712-878, 947-964,
    1112-1188, 1350-1420, 18421929, 2126-2439, and 2709-3438 Ma) show
    sediment influx from varied sources, most likely through grain
    recycling. The major zircon clusters in these sequences match the
    populations recorded in the nearby Acatlan Complex. In contrast, the
    Huetamo sample is dominated by Lower Cretaceous (ca. 126 Ma) zircons of
    local volcanic provenance, and the Zihuatanejo sample contains zircon
    clusters (ca. 259, ca. 579, and ca. 947-1162 Ma) comparable to major
    populations recorded in the underlying Arteaga Complex.
    A sample from the Middle Triassic-Middle JurassicArteaga Complex at
    Tzitzio contains zircon clusters (ca. 202-247, ca. 424, ca. 600, ca.
    971, and ca. 2877 Ma) consistent with an ultimate derivation from both
    North American and SouthAmerican sources. The sample from the Las Ollas
    suite contains comparable zircon populations (ca. 376-475, ca. 575, ca.
    988-1141, and ca. 2642-2724 Ma), and it is interpreted to be part of
    the prevolcanic basement. In contrast, the youngest zircon cluster (ca.
    105 Ma) in the Mexcala Formation coincides with the major volcanic
    events in the Taxco-Taxco Viejo, Teloloapan, and Arcelia assemblages,
    whereas the older clusters (ca. 600, ca. 953, ca. 1215, ca. 1913, and
    ca. 2656-2859 Ma) broadly match the major populations recorded in rocks
    from the Acatlan Complex.
    These new data combined with available geochemical and isotopic data
    indicate that the Taxco-Taxco Viejo arc assemblage developed on
    continental crust. The Acatlan Complex is the most plausible candidate.
    The Teloloapan and Arcelia arc assemblages were developed on oceanic
    crust as offshore arcs facing the Acatlan Complex. The Zihua-tanejo
    terrane assemblages were developed on the Arteaga Complex, and evidence
    no influence from the Acatlan Complex. This suggests that these
    assemblages were formed farther away or in a restricted basin.
    The Guerrero composite and Mixteca arc successions are coeval with the
    Alisitos arc of northern Mexico and in part with the Nevada and Klamath
    ranges of the southwestern United States, and with the arc series from
    the Greater and Lesser Antilles and northern South America. Data
    indicate that during late Mesozoic time, southwestern North America was
    a site of intensive volcanism in a complex arc-trench system similar to
    that of the east Pacific. Our data are consistent with a diachronic
    accretion of the Guerrero composite terrane sequences, beginning during
    late Cenomanian time with the amalgamation of the Teloloapan and
    probably the Arcelia assemblages, and finishing at the end of
    Cretaceous time with the accretion of the Zihuatanejo terrane
    assemblages.

 TI Pressure-temperature-time evolution of Paleozoic high-pressure rocks of
    the Acatlan Complex (southern Mexico): Implications for the evolution
    of the Iapetus and Rheic Oceans

 AB New thermobarometric and U/Pb and Ar-40/Ar-39 geochronologic data
    coupled with ages obtained from the Acatlan Complex, the basement of
    the Mixteco terrane of southern Mexico, reveal the existence of three
    distinctive high-pressure metamorphic events of early to middle
    Paleozoic age, each recorded in a separate lithological suite.
    Xayacatlan suite eclogites with oceanic affinity underwent peak
    metamorphism at 609-491 degrees C and 13-12 kb during the Early
    Ordovician (ca. 490-477 Ma, U-Pb zircon), followed by a partial
    overprint at 600 degrees C and -9.6 kb and then at 500 degrees C and
    -6.7 kb. An overprinting event at 525-500 degrees C and -9.5 kb is
    ascribed to the Devonian. The pressure-temperature (P-T) path of the
    Xayacatlan suite indicates a subduction-exhumation process followed by
    tectonically related reburial. Ixcamilpa suite blueschists with oceanic
    affinity underwent epidote-blueschist metamorphism (T, 200-390 degrees
    C; P, 6-9 kb) and then epidote-mphibolite (T, 390-580 degrees C; P, 9-6
    kb) events ascribed to the Late Ordovician-Early Silurian. Esperanza
    suite eclogites with continental affinity underwent peak metamorphism
    at 830-730 degrees C and 17-15 kb. Amphibole from eclogite yields a 430
    +/- Ma Ar-40/Ar-39 age, dating the high-pressure (HP) event. P-T paths
    of high-temperature (HT) eclogites like those of the Esperanza suite
    have been related to the collision of continental blocks. Partial
    overprinting occurred at 690-640 degrees C and 14-10 kb prior to 374 2
    Ma (Ar-40/Ar-39, phengite). The three HP suites were tectonically
    juxtaposed at different times before the Mississippian Period,
    resulting in the closure of the Iapetus Ocean. Phengite Ar-40/Ar-39
    geochronology reveals the existence of a widespread tectonothermal
    event between 345 and 323 Ma, which may be related to the juxtaposition
    of the HP-composed block and the Gondwanan-affinity Cosoltepec suite,
    causing the closure of the Rheic Ocean. The tectonothermal events in
    the Acatlan Complex coincide in time, physical conditions, and tectonic
    setting with events in the Appalachian- Caledonian orogen, suggesting
    their relation. On that basis the geology of the Acatlan Complex can
    lead to a more comprehensive understanding of the tectonic evolution of
    the Appalachian orogen and of the Gondwana-Laurentia interactions
    preceding the Pangean assembly.

 TI p53 response to arsenic exposure in epithelial cells: Protein Kinase
    B/Akt involvement

 AB Inorganic arsenic is a major environmental contaminant associated with
    an increased risk of human skin cancer. Arsenic modulates cellular
    signaling pathways that affect diverse processes such as cell
    proliferation, differentiation, and apoptosis, including genotoxic
    damage. The p53 protein plays a central role in mediating stress and
    DNA damage responses, leading to either growth arrest or apoptosis.
    Several signal transduction pathways activated under a plethora of
    stressing conditions increase p53 protein levels. To further understand
    the molecular mechanisms involved in the arsenic mode of action, we
    explored the effects of this metalloid on the activation of the
    phosphatidyl inositol 3-kinase (PI3K)/Ca2+/diacylglicerol dependent
    protein kinase/ protein kinase B (PKB) signaling cascade and its
    repercussion in p53 activation in two epithelial cell types: primary
    normal human keratinocytes cultures (NHK) and the carcinoma-derived
    C33-A cell line. Although in both cell systems arsenic leads to an
    increase in p53 and its binding to DNA, the final outcome is different.
    In NHK, arsenic triggers a sustained activation of the
    PI3K/PKB/glycogen synthase kinase-3 beta pathway, driving the cell into
    a cell-differentiated stage in which the proliferation signals are
    turned down. In sharp contrast, in C33-A cells, arsenic leads to a
    transient increase in p53 followed by a drastic reduction in its
    nuclear levels and an increase in cell proliferation. These findings
    favor the notion that p53-stage and transcriptional abilities are
    important to understand modifications in the
    proliferation-differentiation balance, an equilibrium that is severely
    impaired by arsenic.

 AB The El Hundido aquifer, in Coahuila, Mexico, has been increasingly
    exploited by groundwater pumping since the beginning of the year 2001,
    mainly for agricultural purposes. Therefore, there is concern about the
    possible negative effects on the adjoining Cuatrocienegas aquifer,
    which lies under the Cuatrocienegas Natural Protected Area, a site
    containing a great variety of endemic species. The objective of this
    research was to evaluate the hydrodynamic, isotopic, and geochemical
    behavior of the El Hundido aquifer and the possible hydraulic
    interaction with the Cuatrocienegas aquifer in Coahuila. To fulfill
    this objective, field, office, and laboratory activities were carried
    out. The field work included a well census, nine infiltration tests,
    one pumping test, well hydrometry, a topographical leveling survey of
    40 wells, geophysical soundings, a geological field survey, the
    drilling of two test wells to depths of 200 and 250 m, and the taking
    of 103 surface- and groundwater samples for hydrochemical and isotopic
    analyses. The main results of the study are as follows, 1) There is a
    hydrodynamical divide between the groundwater of the Cuatrocienegas
    aquifer and the El Hundido aquifer, 2) The groundwater of the
    Cuatrocienegas aquifer is isotopically distinct from that of the El
    Hundido aquifer, 3) Groundwater salinity in both valleys is due to the
    dissolution of the underlying rocks of marine origin; 4) The
    groundwater source in both valleys is rainwater; while the main water
    source feeding the Cuatrocienegas springs is precipitation falling on
    the La Fragua and the San Marcos mountain ranges.

 AB A novel bacterium, strain BMP-1(T), was isolated from a continuous
    wastewater treatment culture system operating with a bacterial
    consortium. Cells of the isolate were Gram-variable, aerobic,
    moderately halotolerant, motile and endospore-forming rods. Strain
    BMP-1(T) grew chemolithoautotrophically by oxidation of thiosulfate to
    sulfate with a growth yield of 1.07 g protein mol(-1) of thiosulfate
    consumed. DNA G+C content was 43.8 mol%. Its cell wall had
    peptidoglycan based on m-diaminopimelic acid, and the major component
    of fatty acid was C-15 : 0. The 16S rRNA gene analysis showed that
    strain belongs to the genus Bacillus, sharing a 99.5% of sequence
    similarity with Bacillus jeotgali CCM 7133(T). DNA-DNA hybridization
    between the isolate of this study and this strain was 44%. Thus, the
    inclusion of strain BMP-1(T) in the genus Bacillus is suggested as a
    novel species and the name Bacillus thioparus sp. nov. (Type strain
    BMP-1(T)=BM-B-436(T)=CECT 7196(T)) is proposed. The sequence of the 16S
    rRNA gene has been deposited in GenBank with accession number DQ371431.

 AB This paper describes simulations of two context-dependence phenomena in
    Pavlovian conditioning, using a neural-network model that draws on
    knowledge from neuroscience and makes no distinction between operant
    and respondent learning mechanisms. One phenomenon is context
    specificity or the context-shift effect, the decrease of conditioned
    responding (CR) when the conditioned stimulus (CS) is tested in a
    context different from the one in which it had been paired with the
    unconditioned stimulus (US). The other effect is renewal, the recovery
    of CR in the training context after extinction in another context. For
    specificity (simulation 1), two neural networks were first given 200
    CS-US pairings in a context. Then, the CS was tested either in the
    training context or a new context. Output activations in the new
    context were substantially lower. For renewal (simulation 2), two
    networks were first given 200 CS-US pairings in a context, then 100
    extinction trials in either the same context or a new one, and then
    tested back in the training context. Output activations during the test
    phase were substantially higher after extinction in a new context. The
    results are interpreted in terms of the dynamics of activations and
    weights. (c) 2007 Elsevier B.V. All rights reserved.

 AB In this paper we report the oldest geologic world record of Ptychodus
    mortoni, from the Vallecillo Member (Agua Nueva Formation), at
    Vallecillo, Nuevo Leon, northeastern Mexico. The presence of the
    ammonite Watinoceras coloradoense allows the placement of the sediments
    of the Vallecillo member within the lower Turonian (Watinoceras
    coloradoense zone). With reference to this new data, the presence of
    Ptychodus mortoni in the Vallecillo member extend the temporal
    distribution of this species into the earliest Turonian. Also, this
    study suggests that the utility of this shark species as
    biostratigraphic control in late Cretaceous sediments should be revised
    in greater detail.

 AB Objective. To perform the molecular characterization of
    methicillin-resistant Staphylococcus haemolyticus (MRSH) clinical
    isolates from patients in a Mexican hospital. Methods. Sixty three
    Staphylococcus ssp. isolates collected from September 2000 to October
    2002 were analyzed. Antimicrobial susceptibility was determined by disk
    diffusion method and the presence of the mecA gene was detected by PCR
    technique. Isolates characterization was carried out by pulsed field
    gel electrophoresis (PFGE). Results. The frequency of S. haemolyticus
    was 25.5% (18 of 63 clinical isolates), all S. haemolyticus isolates
    were methicillin-resistant and they were positive for the mecA gene. A
    major pattern (A) with 8 subtypes was identified. This clone was
    distributed during the 20 months period. Most of them were isolated
    from the surgery (55%) and pediatric services (27.5%). Conclusion. The
    methicillin-resistant S. haemolyticus permanence as pathogen in this
    hospital, suggest the implementation of control programs in order to
    decrease the prevalence of this multiresistant pathogen.

 AB Experimental cookies were formulated with a resistant starch-rich
    powder (RSRP) prepared from autoclave-treated lintnerized banana
    starch. The products were studied regarding :chemical composition,
    available starch (AS), resistant starch (RS) and rate of starch
    digestion in vitro. In order to evaluate the acceptance of
    RSRP-products, a first affective test was carried out on four cookie
    formulations containing different RSRP levels. The formulation chosen
    corresponded to a wheat flour:RRSP ratio of 15:85. Chemical composition
    of the cookies showed no difference in ash and lipid contents between
    control (100% wheat flour) and RSRP-cookies (P < 0.05). RSRP-cookies
    had higher AS and RS levels than control cookies, from the addition of
    RSRP. The hydrolysis index (HI)-based predicted glycemic index for the
    RSRP-cookies was 60.53, which was significantly lower than for control
    samples (77.62), suggesting a "slow carbohydrate" feature for the
    RSRP-based goods. The second affective test indicated similar
    preference for RSRP-containing cookies and control samples. Results
    reveal RSRP from banana starch as a potential ingredient for bakery
    products containing slowly digestible carbohydrates. (c) 2006 Elsevier

 AB Seventy-nine Trichoderma strains were isolated from soil taken from 28
    commercial plantations of Agave tequilana cv. 'Azul' in the State of
    Jalisco, Mexico. Nine of these isolates produced nonvolatile
    metabolites that completely inhibited the growth of Thielaviopsis
    paradoxa on potato dextrose agar plates. These isolates were identified
    as Trichoderma longibrachiatum on the basis of their morphology and DNA
    sequence analysis of two genes (ITS rDNA and translation elongation
    factor EF-1 alpha). Mycoparasitism of Th. paradoxa by T.
    longibrachiatum strains in dual cultures was examined by scanning
    electron microscopy. The Trichoderma hyphae grew alongside the Th.
    paradoxa hyphae, but penetration of Thielaviopsis hyphae by Trichoderma
    was no apparent. Aleurioconidia of Th. paradoxa were parasitized by
    Trichoderma. Both hyphae and aleurioconidia of Th. paradoxa lost turgor
    pressure, wrinkled, collapsed and finally disintegrated. In liquid
    cultures, all nine Trichoderma isolates produced proteases,
    beta-1,3-glucanases and chitinases that would be responsible for the
    degradation of Thielaviopsis hyphae. These results demonstrate that the
    modes of action of T. longibrachiatum involved against Th. paradoxa in
    vitro experiments are mycoparasitism and the production of nonvolatile
    toxic metabolites.

 AB We present a detailed analysis of the reconstruction of gray-level
    images using orthogonal moments with respect to the basis sets of
    Zernike, Fourier-Mellin, Chebyshev-Fourier, and pseudo-Jacobi-Fourier
    polynomials. As test images, we use Ronchigrams with different numbers
    of fringes as high-spatial-frequency components. The evaluation of
    image reconstruction between orthogonal moment sets is made in terms of
    different metrics. These measurements are the normalized image
    reconstruction error, the overall activity level in each image with
    respect to spatial frequency variations, the root-mean-square contrast,
    the total number of reconstructed fringes, the coordinate
    transformations of the input image, and the number of moment orders.
    Moreover, a method of denoising the input image based on the Daubechies
    wavelet transform is implemented to compute the signal-to-noise ratio.
    Numerical computations show that, for the Ronchigram reconstructions,
    the performance of Zernike moments is better than that of the other
    basis sets of orthogonal moments. (c) 2007 Society of Photo-Optical

 AB Asthma is an inflammatory airway disease characterized by increased
    serum IgE levels, mucus hypersecretion and infiltration of inflammatory
    cells, and is a multifactorial disease that exhibits genetic
    heterogeneity. Polymorphisms in the interleukin-4 (C-590T),
    interleukin-4 receptor (ile50val and gln576arg), and interleukin-13
    (arg130gln) genes have been described as susceptibility alleles for
    asthma. This study was designed to determine whether asthma
    susceptibility is influenced by genotypic and allelic distribution of
    the above polymorphisms in three Mexican subpopulations. Four hundred
    and thirty-seven subjects from three Mexican subpopulations were
    classified into two groups: general population and affected/unaffected
    and genotyped for the above polymorphisms. We compared the
    distributions of the loci in the groups. In addition, we undertook
    association analysis between these loci and asthma phenotype in each
    affected/unaffected group, and determined Nei's genetic distance
    between the three subpopulations. The allelic and genotypic
    distributions of the polymorphisms differed between the three
    subpopulations. There was no association between any of the
    polymorphisms and asthma phenotype. However, there was a differential
    distribution of haplogroups (P < 0.0001) between the affected and the
    unaffected groups from the subpopulations of Jalisco and Guerrero. The
    genetic distribution of the four polymorphisms in the subpopulations
    did not influence susceptibility to asthma. Furthermore, the difference
    in the prevalence of asthma in these subpopulations is not attributable
    to the genetic background for the four polymorphisms analysed. However,
    haplogroup analysis suggests that the interaction of the polymorphisms
    and other predisposing alleles leads to the expression of the clinical
    phenotype.

 AB Appropriate removal of L-glutamate from the synaptic cleft is important
    for prevention of the excitotoxic effects of this neurotransmitter. The
    Na+-dependent glutamate/aspartate transporter GLAST is regulated in the
    short term, by a transporter-dependent decrease in uptake activity
    while in the long term, a receptor's-dependent decrease in GLAST
    protein levels leads to a severe reduction in glutamate uptake. The
    promoter region of the mouse glast gene harbors an Activator Protein-1
    site (AP-1). To gain insight into the molecular mechanisms triggered by
    Glu-receptors activation involved in GLAST regulation, we took
    advantage of the neonatal mouse cerebellar prisms model. We
    characterized the glutamate uptake activity; the glutamate-dependent
    effect on GLAST protein levels and over the interaction of nuclear
    proteins with a mouse glast promoter AP-1 probe. A time and dose
    dependent decrease in transporter activity matching with a decrease in
    GLAST levels was recorded upon glutamate treatment. Moreover, a
    significant increase in glast AP-1 DNA binding was found.
    Pharmacological experiments established that both effects are mediated
    through alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate
    receptors, favoring the notion of the critical involvement of glutamate
    in the regulation of its binding partners: receptors and transporters.

 AB Two new brachyuran species are described for the Upper Cretaceous
    Mexcala Formation, Guerrero State, Mexico. Longilsorbis quadratus new
    species (Coniacian, Temalac region) is the oldest and southernmost
    record for the genus. Xanthosia zoquiapensis new species (Campanian,
    Zoquiapa region) is the first record for the genus in Mexico. In
    addition, the age for Costacopluma bishopi Vega and Feldmann is
    discussed (Coniacian, Temalac region) and represents the oldest and
    southernmost record for Cretaceous representatives of this genus in
    North America. All specimens are considerably smaller compared to other
    species of the same genera and are interpreted as the first example of
    brachyuran dwarfism in the geological record. These species add new
    insight into possible migratory routes during the Late Cretaceous.
    Within Longusorbis, a northwestern migratory route is documented from
    the Coniacian in Mexico to the Campanian-Maastrichtian of the west
    coast of North America (Canada), whereas within the genus Xanthosia, a
    western migratory route from the Albian of Europe to the Campanian of
    Mexico is indicated. Costacopluma migrated east and north to the west
    coast of Africa, southeast North America and Greenland.

 ID LESIONS
 AB We have developed a novel methodology to combine several models using a
    Bayesian approach. The method selects the most relevant attributes from
    several models, and produces a Bayesian classifier which has a higher
    classification rate than any of them, and at the same time is very
    efficient. Based on conditional information measures, the method
    eliminates irrelevant variables, and joins or eliminates dependent
    variables; until an optimal Bayesian classifier is obtained. We have
    applied this method for diagnosis of precursor lesions of cervical
    cancer. The temporal evolution of the color changes in a sequence of
    colposcopy images is analyzed, and the resulting curve is fit to an
    approximate model. In previous work we develop 3 different mathematical
    models to describe the temporal evolution of each image region, and
    based on each model to detect regions that could have cancer. In this
    paper we combine the three models using our methodology and show very
    high accurracy for cancer detection, superior to any of the 3 original
    models.

 TI Context-based gesture recognition
 SO PROGRESS IN PATTERN RECOGNITION, IMAGE ANALYSIS AND APPLICATIONS,
    PROCEEDINGS
 SE LECTURE NOTES IN COMPUTER SCIENCE
 LA English
 DT Proceedings Paper
 AB Most gesture recognition systems are based only on hand motion
    information, and are designed mainly for communicative gestures.
    However, many activities of everyday life involve interaction with
    surrounding objects. We propose a new approach for the recognition of
    manipulative gestures that interact with objects in the environment.
    The method uses non-intrusive vision-based techniques. The hands of a
    person are detected and tracked using an adaptive skin color
    segmentation process, so the system can operate in a wide range of
    lighting conditions. Gesture recognition is based on hidden Markov
    models, combining motion and contextual information, where the context
    refers to the relation of the position of the hand with other objects.
    The approach was implemented and evaluated on two different domains:
    video conference and assistance, obtaining gesture recognition rates
    from 94% to 99.47%. The system is very efficient so it is adequate for
    use in real-time applications.

 AB Banana flour (BF) was obtained from unripe banana (Musa paradisiacal
    L.) and characterized in its chemical composition. Experimental bread
    was formulated with BF flour and the product was studied regarding
    chemical composition, available starch (AS), resistant starch (RS) and
    rate of starch digestion in vitro. The chemical composition of BF
    showed that total starch (73.36%) and dietary fiber (14.52%) were the
    highest constituents. Of the total starch, available starch was 56.29%
    and resistant starch 17.50%. BF bread had higher protein and total
    starch content than control bread, but the first had higher lipid
    amount. Appreciable differences were found in available, resistant
    starch and indigestible fraction between the bread studied, since BF
    bread showed higher resistant starch and indigestible fraction content.
    HI-based predicted glycemic index for the BF bread was 65.08%, which
    was significantly lower than control bread (81.88%), suggesting a "slow
    carbohydrate" feature for the BF-based goods. Results revealed BF as a
    potential ingredient for bakery products containing slowly digestible
    carbohydrates.

 AB Eighty per cent of the total tomato postharvest losses in pre-packaged
    and loose tomato fruits in Mexico were caused by Alternaria rot and
    Rhizopus rot. A sensor was developed to detect Rhizopus stolonifer
    infected tomatoes using three relative humidity sensors. Green and red
    mature tomatoes were inoculated with R. stolonifer conidia on a wound
    and stored for 5 days. A small extractor sucked moist air from the
    tomato peduncle scar through a measuring cavity. The relative humidity
    of air exiting from the peduncle scar was differentiated from the
    ambient air relative humidity and amplified in order to obtain a value
    which could predict infected tomatoes. A compression surface applied a
    controlled pressure to green and red infected tomatoes which were
    detected with accuracies of 91 and 89%, respectively. Peduncle scar
    measurements are more useful as infected tomatoes can be monitored
    non-dependent on its maturity stage and within all the fruit. (c) 2006

 AB Glutamate,uta mate, the main excitatory amino acid transmitter in the
    vertebrate brain is involved in the dynamic changes in protein
    repertoire that underlie synaptic plasticity. Activity-dependent
    differential expression patterns occur not only in neurons but also in
    glial cells. In fact, a membrane to nuclei signaling has been described
    after ionotropic glutamate receptor stimulation in cultured chick
    cerebellar Bergmann glia cells. In order to characterize other levels
    of protein expression regulation, we explored the effect of glutamate
    treatment in [S-35]-methionine incorporation into newly synthesized
    polypeptides. A time-dependent modification in protein synthesis was
    found. An important component of translational control is the ribosomal
    S6 protein kinase. Threonine phosphorylation renders the kinase active
    increasing translation initiation. Glutamate exposure results in
    ribosomal S6 protein kinase Thr(389) phosphorylation in a dose and
    time-dependent manner that matches perfectly with the overall protein
    synthesis profile detected upon the excitatory amino acid.
    Pharmacological characterization of the receptors involved suggests the
    participation of both ionotropic as well as metabotropic glutamate
    receptors. The non-receptor tyrosine kinase Src, phosphatidylinositol
    3-kinase, protein kinase B and the mammalian target of rapamycin are
    mediators of the glutamate effect. These results not only demonstrate
    that glutamate receptors activation is critically involved in
    translational control in glial cells adjacent to synaptic processes
    like cerebellar Bergmann glia cells, but also further strengthen the
    notion of an active participation of glial cells in synaptic
    transmission. (c) 2006 IBRO. Published by Elsevier Ltd. All rights

 AB Non- conventional nixtamalized maize flours elaborated by a factory in
    Mexico were used for tortilla preparation. Tortillas were stored at 4
    degrees C for up to 72 h and the total starch, available starch,
    resistant starch and retrograded resistant starch were assessed. The
    traditional white tortilla, used as a control, showed higher protein
    and fat contents than blue maize tortilla, whereas a maize-bean mixed
    tortilla had the highest protein, ash and fat contents. Lower total
    starch was obtained in the maize-bean tortilla than in white and blue
    maize tortillas. The available starch content in all tortillas
    decreased with the cold-storage, although the change was more marked
    for blue-maize tortillas. The maize-bean mixed tortillas exhibited the
    lowest in vitro digestibility, which is consistent with the relatively
    high resistant starch levels in the bean. Differences in resistant
    starch content were found between the two maize tortillas, which might
    be related to the softer texture of blue-maize tortilla. The starch
    digestibility features of these new types of nixtamalized maize flours
    open up the possibility of producing tortillas with variable
    nutritional properties.

 ID SIMULATION-MODELS
 AB Six maize field experiments conducted in Southeastern Mexico in the
    1997-99 period were analyzed in order to evaluate genotype x crop
    management interaction on harvest index (HI). The validity of using a
    constant value for HI is questioned in modern hybrids of corn, in order
    to predict its growth from some modular, dynamics models which are
    additives and ignores factor interactions. 25 and 27 treatments of a
    rotatable central composite design for N, P, K, population density and
    planting date were assigned to main plots of a split plot design
    replicated twice. Small plots were assigned to 3, 4 or 6 maize hybrids
    that had similar agronomic performance but differing genetic
    backgrounds. An interactive quadratic model for management factors and
    maize hybrids was fit by regression for harvest index (HI). Dummy
    variables valued 0 or I accounted for maize hybrids. Alternatively, a
    quadratic, additive model that ignored maize genotypes was fitted by
    regression. Results reflected genotype x management interaction that
    varied significantly among hybrids and locations in the interactive
    model, causing significant variation in III. Extreme computed HI values
    were 0.32 and 0.60.for H-515 and Hemoc hybrids, respectively. The
    interactive model consistently improved 14 to 47% the determination
    coefficient (R-2) for HI.

 AB Leachates from the El Fraile tailings impoundment (Taxco, Mexico) were
    monitored every 2 months from October 2001 to August 2002 to assess the
    geochemical characteristics. These leachates are of interest because
    they are sometimes used as alternative sources of domestic water.
    Alternatively, they drain into the Cacalotenango creek and may
    represent a major source of metal contamination of surface water and
    sediments. Most El Fraile leachates show characteristics of Ca-SO4, (Ca
    + Mg)-SO4, Mg-SO4 and Ca(SO4 + HCO3) water types and are near-neutral
    (pH = 6.3-7.7). Some acid leachates are generated by the interaction of
    meteoric water with tailings during rainfall events (pH=2.4-2.5). These
    contain variable levels of SO42- (280-29,500 mg l(-1)) and As (<
    0.01-12.0 mg l(-1)) as well as Fe (0.025-2352 mg l(-1)), Mn (0.1-732 mg
    l(-1)), Zn (< 0.025-1465 mg l(-1)) and Pb (< 0.01-0.351 mg l(-1)). Most
    samples show the highest metal enrichment during the dry seasons.
    Leachates used as domestic water typically exceed the Mexican Drinking
    Water Guidelines for sulfate, hardness, Fe, Mn, Pb and As, while acidic
    leachates exceed the Mexican Guidelines for Industrial Discharge Waters
    for pH. Cu. Cd and As. Speciation shows that in near-neutral solutions,
    metals exist mainly as free ions, sulfates and bicarbonates, while in
    acidic leachates they are present as sulfates and free ions. Arsenic
    appears as As(v) in all samples. Thermodynamic and mineralogical
    evidence indicates that precipitation of Fe oxides and oxyhydroxides,
    clay minerals and jarosite as well as sorption by these minerals are
    the main processes controlling leachate chemistry. These processes

 AB This paper presents a new Memetic Algorithm designed to compute near
    optimal solutions for the MinLA problem. It incorporates a highly
    specialized crossover operator, a fast MinLA heuristic used to create
    the initial population and a local search operator based on a fine
    tuned Simulated Annealing algorithm. Its performance is investigated
    through extensive experimentation over well known benchmarks and
    compared with other state-of-the-art algorithms.

 SO NEUROCHEMICAL RESEARCH

 DE PKB; glutamate receptors phosphorylation; Bergmann glia; GSK3-beta; Src
 ID HIPPOCAMPAL-NEURONS; TRANSLATION; NMDA
 AB Glutamate is involved in gene expression regulation in neurons and
    glial cells through the activation of a diverse array of signaling
    cascades. In Bergmann glia, Ca2+-permeable
    alpha-hydroxy-5-methyl-4-isoazole-propionic acid (AMPA) receptors
    become tyrosine phosphorylated after ligand binding and by these means
    form multiprotein signaling complexes. Of the various proteins that
    associate to these receptors, the phosphatidylinositol 3-kinase (PI-3K)
    deserves special attention since D3-phosphorylated phosphoinositides
    are docking molecules for signaling proteins with a pleckstrin homology
    domain. In order to characterize the role of PI-3K in AMPA receptors
    signaling, in the present report we analyze the involvement of the
    serine/threonine protein kinase B in this process. Our results
    demonstrate an augmentation in protein kinase B phosphorylation and
    activity after glutamate exposure. Interestingly, the effect is
    independent of Ca2+ influx, but sensitive to Src blockers. Our present
    findings broaden our current knowledge of glial glutamate receptors
    signaling and their involvement glutamatergic neurotransmission.

 AB Cervical cancer constitutes a major health problem in Mexico and other
    developing countries. The purpose of our study was to assess the
    experience of a comprehensive national oncological reference center on
    pelvic exenteration for post-radiotherapy recurrent or persistent
    cervical cancer, describing the prognostic value of time to recurrence,
    procedure complications, and survival. Medical records from 42 patients
    with post-radiotherapy recurrent or persistent cervical cancer who
    underwent a pelvic exenteration with curative purposes from 1984 to
    1989 were retrospectively reviewed. Histological diagnoses were
    squamous cell carcinoma (32 patients), adenosquamous carcinoma (9
    patients), and adenocarcinoma (I patient). Average follow up was of
    56.3 mo after the procedure and global survival at 5 yr was 65.8%.
    Survival for patients with early recurrence was 56.9% vs 78% for
    patients with late recurrence (p = 0.05). Complications were observed
    in 65.3% of the cases with a surgical mortality of 4.8%. Pelvic
    exenteration is a surgical procedure with high morbidity in spite of
    the recent medical advances. Pelvic exenteration should not be
    indicated with palliative purposes owing to the high rate of
    complications. Patients with tumor persistence or early recurrence have
    a worse prognosis. In well-selected cases, exenteration may provide a
    survival benefit.

    copper sulfide mineralization. Rhenium and osmium isotopes are used
    here to constrain the age of hypogene mineralization and the source of
    osmium contained in these ore minerals. A Re-Os isochron yielded an age
    of 160 +/- 16 Ma (2 sigma), with an associated initial Os-187/Os-188
    ratio of 1.06 +/- 0.09 (mean square of weighted deviates=1.8). This age
    is consistent with available geochronological data from volcanic rocks
    that host the mineralization and associated alteration phases. The high
    initial Os-187/Os-188 ratio indicates a lower crustal component for the
    source of Os and, by inference, the Cu sulfides that contain this Os.
    Late hematite occurs as an isolated phase or, more commonly, is
    associated with the chalcocite-bornite and supergene
    chalcocite-covellite associations. Analyses performed on pure hematite
    indicate a disturbance of the Re-Os system, and hence, this mineral
    phase is not useful as a Re-Os geochronometer.

 AB Several compositions in the CaO-ZrO2) system were synthesized from
    zirconium n-butoxide and calcium methoxide, by the sol-gel method.
    Hydrolysis and gelation occurred at pH 3, using H2SO4 as hydrolysis
    catalyst. Fresh gels were annealed in air at 100 to 900 degrees C, in
    100 degrees C steps every 20 h, for a total annealing time of 140 h.
    Analysis by X-ray diffraction showed the formation of hydrated calcium
    sulfate together with amorphous zirconia up to 400 degrees C. At the
    ZrO2 rich-end, tetragonal and monoclinic zirconia solid Solutions were
    stabilized in the presence of Ca ions. When 20 and 30 wt% of CaO were
    added, cubic zirconia and CaZrO3 solid solutions were observed above
    700 degrees C. At the CaO rich-end, the coexistence of calcium
    carbonate polymorphs as vaterite and calcite were observed. Anhydrite
    was present across the entire range of compositions studied from 300 to
    900 degrees C.

 AB The production of resistant starch from non-conventional sources using
    an extruder was studied. Starch was isolated from unripe banana and
    mango fruits, commercial corn starch was used for comparison purposes.
    Moisture, ash and fat content were higher in non-conventional starch
    sources than in corn starch, but corn starch presented a lower protein
    and dietary fibre content than banana and mango starches. Amylose
    content was higher in banana and mango starches than in corn starch.
    Besides, mango had the smallest granule size (5-10 mu m). Extruded
    mango had the lowest solubility which may be related with the granule
    size, and in the case of the swelling, extruded products from corn
    starch had the highest values, a pattern that may be due to the
    amylose/amylopectin ratio, because corn starch had the lowest amylose
    content of the starches studied. Extruded products from mango presented
    a resistant starch (RS) content that decreased when the screw speed
    increased, for banana starch, the RS values from the extruded products
    was similar at 30 rpm and 65 rpm, and at 40 rpm it was the highest. In
    the case of retrograded resistant starch (RRS), the values of the
    extruded products prepared with non-conventional starches had a defined
    pattern, because they decreased when screw speed increased.

 ID SEASON
 AB The objective of the present study was to evaluate the fertility rate
    and prolificity index of Creole goats, either inseminated into the
    uterus with cooled semen, or served by natural mating. The study took
    place during the breeding season. Goats were synchronized with
    intravaginal sponges containing 40 mg of flurogestone acetate (FGA)
    during 11 d, plus an intramuscular injection of equine corionic
    gonadotropin (eCG) when sponges were withdrawn. Goats were served
    either by natural mating (n=41) or inseminated into the uterus by
    laparoscopy (n=40) with cooled semen 24 h after estrus was detected.
    Data were analyzed by chi(2) tests and variance analysis. The fertility
    rate (82.5%) obtained by natural mating was higher (p <= 0.05) than
    that obtained by artificial insemination (67.5%). No differences were
    found (p > 0.05) for the prolificity rate between natural mating (1.20
    +/- 0.41 kids per goat) and artificial insemination (1.18 +/- 0.39 kids
    per goat). It is concluded that a moderate fertility was obtained by
    cooled semen, however, it was lower than that registered for natural
    mating. Prolificity index was not affected by the form in which goats
    were served.

 AB U-Pb geochronologic analyses have been conducted on 135 detrital zircon
    grains from Pateozoic strata of the Oaxaca terrane of southern Mexico.
    The grains are mainly mid-Proterozoic in age (age probability peak of
    993 Ma), with subordinate clusters of similar to 358 and similar to 472
    Ma. The mid-Proterozoic ages can be used to evaluate three possible
    paleopositions for the Oaxaca terrane during mid-Proterozoic time.
    Formation in proximity to northwest South America appears most likely,
    as southwestern portions of the Amazon craton (and perhaps basement
    massifs in the northern Andes) contain igneous rocks of the appropriate
    age. A more specific test of ties to these regions is not yet possible
    due to the limited number of U-Pb determinations from the region.
    Formation in proximity to Grenville-age rocks in northeast North
    America is less likely, as detrital zircons shed from these rocks are
    mostly older than 993 Ma. Previously proposed links with Grenville-age
    rocks in southwestern North America are not supported by our data, as
    there is little overlap of ages from the Oaxaca terrane and from
    Grenville-derived detrital zircons in southwestern US and northwestern
    Mexico. The presence of Paleozoic grains in our samples does not help
    constrain the Late Proterozoic-early Paleozoic displacement of the
    Oaxaca terrane, as magmatism of this age was apparently widespread
    within and adjacent to the Iapetus and Rheic ocean basins. (c) 2005

 DE recombination operators; memetic algorithms; linear arrangement
 AB In this paper the Minimum Linear Arrangement (MinLA) problem is studied
    within the framework of memetic algorithms (MA). A new dedicated
    recombination operator called Trajectory Crossover (TX) is introduced
    and its performance is compared with four previous crossover operators.
    It is shown that the TX crossover induces a better population
    diversity. The MA using TX is evaluated on a set of well-known
    benchmark instances and is compared with several state-of-art MinLA
    algorithms.

 AB Field studies were conducted in the sugarcane area of Los Mochis,
    Sinaloa, Mexico, from December 1994 to December 2001 to determine the
    establishment and impact of the introduced braconid Macrocentrus
    prolificus Wharton on the crambid stalkborers Diatraea considerata
    Heinrich, D. grandiosella Dyar, and Eoreuma loftini (Dyar). A total of
    ca. 200,000 M prolificus adults were liberated in each of five, 10-ha
    fields during May-December 1995. Fields were sampled monthly for
    stalkborer larvae and M prolificus parasitism from 1995 to 2001. Total
    stalkborer larvae averaged 2.9 per stalk during the period of study,
    with D. considerata, D. grandiosella, and E. loftini comprising 78.1,
    21.2, and 0.7% of the total, respectively. Recovery of M prolificus
    from field-collected stalkborer larvae began soon after initial
    releases, with average parasitism < 3% during 1995-1997, increasing to
    6% in 1998, and stabilizing at 10-12% during 1999-2001. Average
    (all-years) parasitism was highest for D. considerata and lowest for E.
    loftini.

 AB Objective. The occurrence of physical abuse during pregnancy,
    identifying associated factors and outcomes for women's health was
    estimated.
    Material and Methods. A cross-sectional community-based study in
    Ometepec in the Mexican state of Guerrero identified women who reported
    at least one pregnancy in the three years prior to the survey. These
    completed a questionnaire administered by a female nurse.
    Results. Out of 2389 women in Ometepec, 709 were eligible to complete
    the questionnaire. Among those interviewed without being present their
    partners/husbands, 21% reported a history of physical abuse and 5.6%
    reported physical abuse during the last pregnancy. There was a strong
    association between physical abuse in pregnancy and the report of
    vaginal bleeding. This suggests that physical abuse might be linked to
    miscarriage (p=0.06). We found little recognition of physical abuse as
    cause of obstetrical problems. There was also an association between
    physical violence during pregnancy and the admission of violent
    reactions against children, based on a hypothetical scenario of
    disobedience.
    Conclusions. This study identified important associations between
    obstetrical problems and physical violence.

 AB Objective. To determine the validity of the presumptive tests used to
    analyze urine in order to detect urinary tract infections in patients
    with diabetes mellitus type-2.
    Material and Methods. In 2001, a cross-sectional study was carried out
    in 160 patients with diabetes mellitus type-2 who were clinically
    diagnosed with urinary tract infections. Patients were from Tlapa,
    which is located in the state of Guerrero. Urine samples were
    microscopically analyzed to determine the number of leukocytes and
    bacteria in centrifuged samples and urine without centrifuge. The
    leukocyte esterasa and nitrites were measured using reactive strips.
    All samples were subjected to urine culture to confirm urinary tract
    infections. Sensitivity, specificity, and predictive values were
    calculated for leukocyte count, bacteriuria, leukocyte esterasa and
    nitrites using positive urine cultures as the standard of measurement.
    Results. Urinary tract infections were confirmed in 31% of patients.
    The presence of bacteria in centrifuged urine, leukocyte esterasa and
    the leukocyte count were all high with respect to sensitivity and
    specificity.
    Conclusions. Leukocyte esterasa and microscopic bacteriuria
    measurements in centrifuged urine offer reliability in the early
    diagnosis of urinary tract infections.

 AB The objective of this study was to evaluate the fertility rate of
    Pelibuey ewes when applying intrauterine insemination with laparoscopy
    utilizing aspic (AI-aspic Group), or modifying the technique utilizing
    an intravenous catheter (AI-catheter Group). Timed insemination by
    laparoscopy with defrosted semen was practiced on 21 cycling adult
    Pelibuey ewes 48 h after removing the sponges. For estrus
    synchronization, the females were treated with intra-vaginal sponges
    (with 40 mg of flurogestone acetate) for 11 days, plus an intramuscular
    injection of 200 IU of eCG when the sponges. Data were subjected to
    analysis of variance and chi(2) test. The average time per inseminated
    ewe (2.60 +/- 0.56 min) was less (p <= 0.001) for the AI-aspic Group
    than the insemination time for AI- catheter Group (6.01 +/- 0.48 min
    per ewe), but there was no difference (p>0.05) for the fertility rate
    between AI-aspic (40.0%) and AI-catheter(50.0%). It was concluded that
    fertility was similar at employing aspic or catheter technique;
    however, the average time per inseminated ewe was significantly shorter
    utilizing the aspic technique.

 AB In some stages of the breeding of crops, breeders must select the most
    promising lines from a very large number of sets of new varieties.
    Selection is conducted via direct comparison of new varieties that are
    tested within a single experimental unit, with control varieties
    systematically intercropped among them and replicated over a large
    number of plots. Researchers often do not realize that, by following
    some simple design rules, they might be susceptible of a precise and
    accurate statistical analysis. This paper discusses the subject with
    precision, and establishes rules of design and a statistical analysis
    technique appropriate for completely randomized experimental designs or
    randomized complete blocks with blocks of the same size.

 AB An adaptation of a hierarchical linear model with two levels is
    proposed for the analysis of a series of experiments under a completely
    randomized design, followed by a brief review of the classical models
    for some experimental designs. This proposal considers as first level
    data those obtained from each experiment in each location. In the
    second level the variability among experiments is reviewed using one
    explanatory variable measured at the location level. This procedure
    allows to explain the variability of the treatment means through the
    locations.

 AB Resistant starches were prepared from mango starch by extrusion. An
    experimental design with independent variables temperature, screw speed
    and moisture content produced 20 samples that were studied to determine
    the effect of these variables on resistant starch (RS) content, water
    absorption index (WAI) and water solubility index (WSI). RS content was
    affected by moisture content and temperature. Screw speed and
    temperature also influenced RS content, the highest level (97 g kg(-1))
    being obtained at low screw speed and high temperature, this pattern
    can be associated with a longer residence time, which gives rise to
    more opportunity for amylose chain association. The regression model
    fitted to the RS experimental results showed a good correlation
    coefficient (0.80). When moisture content and temperature decreased,
    WAI increased (105-142 g kg(-1)), but low WAI values (70-77 g kg(-1))
    were obtained at moisture contents between 200 and 300 g kg(-1) and
    high temperatures (140-150 degrees C). When moisture content and
    temperature increased, WSI increased (222-332 g kg(-1)), but at high
    temperature value (120 degrees C) assayed and the lowest moisture
    content (150 g kg(-1)), WSI also increased. In the range of moisture
    contents tested and at low temperatures, only partial gelatinisation
    occurred and low solubility was obtained. (c) 2005 Society of Chemical

 TI Household cost-benefit equations and sustainable universal childhood
    immunisation: a randomised cluster controlled trial in south Pakistan
    [ISRCTN12421731]
 SO BMC PUBLIC HEALTH
 LA English
 DT Article
 ID DISEASE
 AB Background: Household decision-makers decide about service use based
    largely on the costs and perceived benefits of health interventions.
    Very often this leads to different decisions than those imagined by
    health planners, resulting in under-utilisation of public services like
    immunisation. In the case of Lasbela district in the south of Pakistan,
    only one in every ten children is immunised despite free immunisation
    offers by government health services.
    Methods/design: In 32 communities representative of Lasbela district,
    3344 households participated in a baseline survey on early child
    health. In the 18 randomly selected intervention communities, we will
    stimulate discussions on the household cost-benefit equation, as
    measured in the baseline. The reference (control) communities will also
    participate in the three annual follow-up surveys, feedback of the
    general survey results and the usual health promotion activities
    relating to immunisation, but without focussed discussion on the
    household cost-benefit equations.
    Discussion: This project proposes knowledge translation as a two-way
    communication that can be augmented by local and international
    evidence. We will document cultural and contextual barriers to
    immunisation in the context of household cost-benefit equations. The
    project makes this information accessible to health managers, and
    reciprocally, makes information on immunisation effects and side
    effects available to communities. We will measure the impact of this
    two-way knowledge translation on immunisation uptake.

 AB Feeding habits of the fishes Lutjanus peru and Lu janus guttatus
    (Pisces: Lutjanidae) of Guerrero, Mexico. Diet composition of the
    Pacific snapper (Lu janus peru) 130-684 mm fork length (FL) and the
    spotted snapper (Lu janus guttatus) 120-550 mm FL, was analyzed.
    Monthly samples were obtained from commercial landings in three regions
    off the coast of Guerrero, Mexico. Percentage by number (%N),
    percentage by weight (%W), and percentage of occurrence (%O) were
    calculated for each prey and summarized as the index of relative
    importance. Both species are polyphagous predators feeding on a variety
    of prey: Sixty-eight prey items, mainly fish (%W = 50.9), crustaceans
    (%W = 35.6), and mollusks (%W = 7.2), were found in the stomach
    contents of L. peru, while 88 components were identified in the diet of
    L. guttatus, the most important prey being fish (%W = 50.8) and
    crustaceans (%W = 43.4). Diet overlap between species is not
    significant (p < 0.05), indicating that competition for food is
    unlikely. Based on published values of the relative importance index,
    the diets of these Lutjanidae were analyzed considering different
    regions of the Pacific coast of Mexico and Costa Rica, and similarities
    among sites and species were discussed. The cluster analysis showed
    that similarities among species inhabiting in the same area are more
    important than within organisms of the same species living in different
    zones. Results suggest that prey availability rather than food
    selectivity, conditions the feeding behavior of these fish species.

 ID GROWTH; RATES
 AB The peninsular pronghorn (Antilocapra americana peninsularis) in the
    Baja California peninsula is an endangered subspecies. We constructed
    captive breeding facilities in the Vizcaino Desert within the current
    range of peninsular pronghorn to assist in population recovery. The
    captive breeding facilities included fences, shade, feeders, an
    irrigation system, observation towers, housing for caretakers, and a
    visitor center. We document the initial 6-year cycle of the captive
    management, 1 step of the recovery effort, from the first capture of 5
    fawns in 1998 to 90 captive peninsular pronghorns by the end of 2003.
    We identified problems with the captive breeding facility (e.g.,
    identification of animals and movements into, and accidents with,
    fences), but overall the facility has been a success. We projected the
    first potential translocation of animals into the wild in 2004. If the

 AB Even though the Acatlan Complex in southern Mexico contains the largest
    exposure of Paleozoic rocks in Mexico, it is commonly ignored in
    reconstructions of Pangea because of poor geochronologic data.
    Presently, this complex is understood to be composed of metasedimentary
    units (Cosoltepec, Magdalena, Chazumba and Tecomate Formations), a
    major magmatic suite (Esperanza Granitoids), and a suite with eclogites
    and blueschists (Xayacatlan Fm). Sedimentary cover includes
    unmetamorphosed upper Paleozoic units. Here we provide single-crystal
    laser ablation U-Pb geochronology of the metasedimentary and magmatic
    suites of the Acatlan Complex and its upper Paleozoic sedimentary
    cover. The data reveal a complex geological evolution recording
    tectonic events from the assembly of Rodinia to the break-up of Pangea.
    Data for the Esperanza Granitoids record three major tectonothermal
    events: (1) a Grenvillian (1165 +/- 30 to 1043 +/- 50 Ma), (2) a
    Taconian (478 +/- 5 to 471 +/- 5 Ma), and (3) a Salinian (Acatecan; 461
    +/- 9 to 440 +/- 14 Ma). Eclogitic rocks from the Xayacatlan Formation
    of Neoproterozoic-Early Ordovician age contain detrital zircons derived
    most probably from the southwestern North America Grenville province.
    Data for the blueschists are consistent with a Middle Ordovician
    depositional age and derivation from Laurentian sources. The Tecomate
    Formation is composed of two unrelated units of contrasting age and
    lithology: a Neoproterozoic-Early Ordovician, arc- and rift-related
    volcanosedimentary unit containing detrital zircons derived from the
    southwestern North America Grenville province; and an essentially
    sedimentary unit containing Early Permian fauna. The Cosoltepec
    Formation has a maximum Devonian depositional age and contains detrital
    zircons consistent with derivation from South American sources. The age
    of the Magdalena and Chazumba Formations is established to be Late
    Pennsylvanian-Early Permian. These units contain detrital zircons
    indicating ultimate derivation from both North and South America
    crustal sources. The Late Paleozoic sedimentary cover contains detrital
    zircons shed mainly from Grenvillian sources with a significant
    contribution of Pennsylvanian magmatic rocks.

 AB Mango (Mangifera indica) is a fruit that grows in tropical regions. The
    aim of this work was to isolate the starch from two varieties of mango
    highly consumed in Mexico ("criollo" and "manila"), and to evaluate its
    chemical composition. along with some morphological, physicochemical
    and functional properties. Mango starch had an amylose content of about
    13%, the fat content of "criollo" variety starch (0.1-0.12%), was
    similar to that of commercial corn starch used as control (0.2%); both
    mango starches had higher ash amount (0.2-0.4%) than corn starch. Mango
    starches presented a smaller granule size (10 &mu; m) than corn starch
    (15 &mu; m). along with an A-type X-ray diffraction pattern with slight
    tendency to a C-type. All values of water retention capacity (WRC)
    increased with the temperature. When the temperature increased,
    solubility and swelling values increased and in general, mango starches
    had higher values than corn starch. Both mango starches had
    gelatinization temperatures lower than the control, but "criollo"
    variety starch presented higher enthalpy values than "manila" variety
    and corn starches. Overall, it was concluded that due to its
    morphological, physicochemical and functional properties, mango
    starches could be a feasible starch source with adequate properties,
    suitable for using in the food industry.

 AB The San Salvador Patlanoaya section (Puebla State of Mexico) has been
    subdivided into seven informal members labeled A-F. Members C-F have
    been dated as Missourian to Leonardian (equivalent to Kasimovian to
    Kungurian, i.e. lower Upper Pennsylvanian to upper Lower Permian).
    Members C-E display a shallowing-upward trend as does member F. The
    biodiversity of these carbonate deposits outcropping in the San
    Salvador Patlanoaya section is relatively low, although multiple
    microfossils (algae, small foraminifera, fusulinids and fish remains)
    are represented. Member C consists of calcarenitic limestone
    interpreted as distal tempestites interbedded with shaly limestone
    facies. These storm beds are composed mainly of silt, sand-sized quartz
    grains and bioclasts. Member D corresponds to coarse bioclastic
    limestones represented by calcareous tempestites and channel beds with
    erosional bases. Member E is com posed of green shales and cross-bedded
    sandstones and gravelly conglomerates. Member F corresponds to a
    condensed package of limestones and interbedded silicielastics and is
    Cisuralian (Early Permian) in age. Member G consists of condensed black
    shales and limestone nodules. The results of the study have significant
    implications for recognition of climatic and/or sea-level fluctuations
    in bioclastic-siliciclastic facies during the Late Pennsylvanian-Early
    Permian. The skeletal limestones and channel sandstones, common
    throughout the Pennsylvanian-Permian section, provide a constraint on
    palaeobathymetry, with the water depth fluctuating frequently around a
    position below, but near, the storm wave base.

 AB The San Salvador Patlanoaya section (Puebla State, Mexico) is known for
    its richness of many fossil groups. Among them, the calcareous shells
    have been principally investigated. This paper deals with
    Missourian-Virgilian (Late Pennsylvanian) and Leonardian (late Early
    Permian) Mexican fish remains. A discussion about Helicoprion and
    related genera, is followed by the systematic description of the
    revised or discovered taxa: Cooperella typicalis, Moreyella cf. M.
    typicalis, M. (?) sp., "Sturgeonella" quinqueloba, Hybodontidae gen.
    sp. 1 and 2, scale indet. Pal aeobiogeographic implications are
    suggested. (C) 2005 Elsevier SAS. All rights reserved.

 AB Knowledge of the reproductive cycle of marine invertebrates of economic
    importance is essential for management of natural stocks and to
    initiate aquaculture activities. The reproductive biology of Nodipecten
    subnodosus from Laguna Ojo de Liebre, B.C.S., Mexico, was studied
    during a period of 25 mo. N. subnodosus is a functional hermaphrodite
    in which the follicles contain gametes of only one sex and remain
    separated from those containing the gametes of the other sex, with
    female follicles being dominant. Histologic evidence revealed that the
    lion's-paw scallop may remature at least once during the reproductive
    season. The temperature, analyzed as a single factor, could be
    important in the initiation of gametogenesis and/or as a spawning
    stimulus. The reproductive cycle shows a clear seasonality related to
    the water temperature, which is supported by the temporal variation of
    the oocyte diameter and by a significant positive correlation between
    GSI and temperature. The inactive period occurs from December to March.
    with low water temperature (16degreesC to 17.5degreesC). The
    gametogenesis started when the water temperature reached 18degreesC
    (April). The maximum maturation (90% to 100% of organisms) was reached
    in August when the temperature was highest (23.5degreesC). Spawning
    occurred in September when water temperature decreased. A slight
    reproductive activity during the cooler months (December to March) was
    observed. But, during 2002 the reproductive activity in that period was
    more pronounced and the slight spawning activity was extended to May.
    This behavior was in accordance with temperature anomalies that
    occurred in 2002. Then, N. subnodosus is potentially capable of
    spawning throughout the year if the environmental conditions are
    favorable. The length at first maturity obtained for N. subnodosus was
    135-mmSL.

 TI Molluscan communities of the rocky intertidal zone at two sites with
    different wave action on Isla la Roqueta, Acapulco, Guerrero, Mexico
 SO JOURNAL OF SHELLFISH RESEARCH
 LA English
 DT Article
 DE molluscan communities; rocky intertidal; wave action; Acapulco
 AB Molluscan communities were studied on two shores, one exposed and the
    other sheltered from wave action by determining the diversity,
    richness, density, dominance, and similarity of the groups of species
    found in the upper part of middle intertidal zone. The sample area per
    location and date was 20 m(2). The samples were taken quarterly during
    the year. Species richness was found to be 44 species for both sites
    combined. The exposed site had a greater richness (41 species) and
    lower density (64.2 organism/m(2)), whereas the sheltered site showed a
    higher density (88.08 organisms/m(2)) and smaller richness (33
    species). Thirty species (68.8%) were determined to be common. The
    exposed shore had more confined species. The Shannon-Wiener diversity
    index (H') was higher for the exposed site (3.165 bits/individual). A
    comparison of means by the Mann-Whitney tested indicated that the
    annual means of H' were equal between the two sites. Qualitative
    (Jaccard) and quantitative (Morisita-Horn) similarity scores were high
    at 0.682 and 0.622, respectively. The mean density of gastropods was
    the same at both locations, because bivalves showed significant
    differences with higher densities at the sheltered site. The
    malacologic community of the two sites was very similar. However,
    changes in richness and diversity over time were greater at the
    sheltered shore while these changes were more gradual at the exposed
    shore, reflecting a greater stability of the malacologic Community at
    the latter location.

 AB Banana starch was isolated and used for preparation of two types of
    cookies. Chemical composition and digestibility tests were carried out
    on banana starch and the food products, and these results were compared
    with corn starch. Ash, protein, and fat levels in banana starch were
    higher than in corn starch. The high ash amount in banana starch could
    be due to file potassium Content present in this fruit. proximal
    analysis was similar between products prepared with banana starch and
    those based on corn starch. The available starch content of the banana
    starch preparation was 60% (drub). The cookies had lower available
    starch than the starches while banana starch had lower susceptibility
    to the in vitro alpha-amylolysis reaction. Banana starch and its
    products had higher resistant starch levels than those made with corn
    starch.

 TI The family as a determinant of stunting in children living in
    conditions of extreme poverty: a case-control study

    PREVALENCE; HEALTH; INFECTIONS
 AB Background: Malnutrition in children can be a consequence of
    unfavourable socioeconomic conditions. However, some families maintain
    adequate nutritional status in their children despite living in
    poverty. The aim of this study was to ascertain whether family-related
    factors are determinants of stunting in young Mexican children living
    in extreme poverty, and whether these factors differ between rural or
    urban contexts.
    Methods: A case-control study was conducted in one rural and one urban
    extreme poverty level areas in Mexico. Cases comprised stunted children
    aged between 6 and 23 months. Controls were well-nourished children.
    Independent variables were defined in five dimensions: family
    characteristics; family income; household allocation of resources and
    family organisation; social networks; and child health care.
    Information was collected from 108 cases and 139 controls in the rural
    area and from 198 cases and 211 controls in the urban area. Statistical
    analysis was carried out separately for each area; unconditional
    multiple logistic regression analyses were performed to obtain the best
    explanatory model for stunting.
    Results: In the rural area, a greater risk of stunting was associated
    with father's occupation as farmer and the presence of family networks
    for child care. The greatest protective effect was found in children
    cared for exclusively by their mothers. In the urban area, risk factors
    for stunting were father with unstable job, presence of small social
    networks, low rate of attendance to the Well Child Program activities,
    breast-feeding longer than six months, and two variables within the
    family characteristics dimension (longer duration of parents' union and
    migration from rural to urban area).
    Conclusions: This study suggests the influence of the family on the
    nutritional status of children under two years of age living in extreme
    poverty areas. Factors associated with stunting were different in rural
    and urban communities.
    Therefore, developing and implementing health programs to tackle
    malnutrition should take into account such differences that are
    consequence of the social, economic, and cultural contexts in which the
    family lives.

 AB Historically, specimens representing the Peromyscus boylii species
    group from west-central Mexico have been referred to as Peromyscus
    boylii; however, a distinct but polymorphic karyotype (fundamental
    number 54-56) precludes an assignment of these specimens to currently
    recognized taxa. Phylogenetic analyses (parsimony, likelihood, and
    Bayesian) of DNA sequences indicated that samples from Durango, Mexico,
    formed a monophyletic clade that either was sister to P. levipes
    (parsimony) or to a clade containing P. beatae and P. levipes
    (likelihood and Bayesian). To refer these samples to P. boylii results
    in paraphyly and a significantly worse topology. Together, these
    results indicate that the samples from the Sierra Madre Occidental
    region of Durango and southeastern Sinaloa represent an undescribed
    species of Peromyscus. This taxon is described herein as a new species.

 AB Mexico is one of the main exporters of fresh mango, and quality is
    essential for continuous marketing. Mango is kept for up to 2 days in
    the packinghouse after harvesting and sent to different markets. The
    fruit is packed on 26 kg plastic or wood boxes and firmness sorting can
    avoid mango damage during transport. Mango was detected by firmness on
    a conveyor belt built for a packinghouse using an instrumented sphere
    as detector. The machine was able to detect mango firmness with an
    accuracy of 95(.)7%, using Tukey's biweight robust regression
    algorithm. Simulating supermarket shelf-life, mangoes were classified
    as hard, soft or very soft with an accuracy of 90% using a
    piezoelectric accelerometer at a speed of one fruit per second. (C)

 AB Small farmers' perceptions of coffee Coffea arabica L. herbivores and
    their natural enemies, how those perceptions relate to field
    infestation levels, and pest management practices being implemented by
    members from two organic and nonorganic coffee grower organizations in
    the Soconusco region, southeastern Mexico, were analyzed through an
    interview survey, diagnostic workshops, and field sampling. The terms
    pest, disease, and damage were commonly used as synonyms. The major
    phytophagous species, as perceived by the interviewees, were
    Hypothenemus hampei (Ferrari), and to a lesser extent the fungi
    Corticium koleroga Cooke (Hohnel) and Hemileia vastatrix Berkeley &
    Broome. Among the nonorganic farmers, other nonpest-related constraints
    were regarded as more important. Awareness of the existence of natural
    enemies was low, despite more organic farmers have used the
    ectoparasitoid bethylid Cephalonomia stephanoderis Betrem against H.
    hampei. Labor supplied by household members was most frequent for pest
    control; only organic farmers exchanged labor for this purpose. The
    levels of infestation by H. hampei, Leucoptera coffeella
    Guerin-Meneville, and C. koleroga were lower within the organic coffee
    stands. However, a low effectiveness for pest control was commonly
    perceived, probably due to a feeling, among the organic farmers, of a
    low impact of their pest management extension service, whereas a lack
    of motivation was prevalent among the nonorganic farmers, shown by a
    concern with their low coffee yields and the emigration of youth. The
    importance of understanding farmers' perceptions and knowledge of pests
    and their natural enemies and the need for participatory pest
    management approaches, are discussed.

 AB Objective. To assess the effect of different cooking times and
    temperatures, as well as of some seasonings, on the viability of Taenia
    solium metacestodes in spicy meat and hot sausage. Material and
    Methods. This study was conducted by the Universidad Autonoma de
    Guerrero (Guerrero StateAutonomous University), Mexico in 1999.
    Infected pork meat was bought in the community of Azacoaloya, in the
    municipality of Chilapa de Alvarez, Guerrero State. It was used to
    prepare spicy meat (adobada) and hot sausage (chorizo). Only the meat
    in which metacestode viability was proven was used. The products
    obtained underwent a) room temperature for 12 to 100 hours; b)
    temperatures of -10 to 37degreesC for 24 hours; c) boiling (97degreesC)
    from 1 to 15 minutes. To determine the effect of the seasonings,
    batches were prepared using twice the amount of a specific seasoning.
    Trials were done and assessed three times. Proportion differences were
    established using the chi-squared test. Results. At room temperature
    the lowest evagination occurred after 100 hours for both products
    (p<0.05). After 24 hours, the lowest evagination occurred at
    -10degreesC in spicy meat and at 37degreesC in hot sausage (p<0.05). At
    boiling temperature there was no evagination after 10 minutes (p<0.05).
    In spicy meat, adding salt caused the most significant reduction; in
    hot sausage, thyme caused the most significant reduction (p<0.05).
    Conclusions. Meat with metacestodes should not be eaten, yet, it is
    being sold and used to prepare spicy meats. Adding spices can hide the
    metacestode, thus, adequate cooking of these meat products is
    necessary. These meats may be consumed at least four days after its
    preparation and spicy meat after a minimum of four days of
    refrigeration. The English version of this paper is available at:

 DT Article
 DE Ejidal leasing; ejidatario; multinational company; melon production
 AB Contract agriculture (CA), related to the Mexican sector of ejidos
    (common lands) is seen as a way of development or as a form of
    exploitation; an intermediate approach seeks a balance point between
    its advantages and disadvantages. From this viewpoint, a revision was
    carried out on the experience of the Tziritzicuaro ejido with the
    multinational company (MC) Legumbrera San Luis S. A. de C. V In this
    research quantitative and qualitative methods and techniques were used
    to determine that the link between the ejido and the MC benefits income
    and employment of the ejidatarios (holders of a share in an ejido)
    although it does not set the bases for a sustained development derived
    from an insertion of producers in a global market. However, ejidatarios
    believe the presence of the MC is positive.

    ACTIVATION
 AB Glutamate, the major excitatory neurotransmitter, induces a wide array
    of signals from the membrane to the nucleus regulating gene expression.
    In Bergmann glia, Ca2+-permeable
    alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA)
    receptors are involved in the short- and long-term interactions between
    these cells and the neurons that they surround. After activation, AMPA
    receptors become tyrosine phosphorylated and by these means form
    multiprotein signaling complexes. To characterize these events,
    cultured chick Bergmann glia cells as well as chick cerebellar slices
    were exposed to glutamate, and, by using a combination of
    immuno-precipitation assays coupled to Western blot analysis, we
    identified several signaling proteins that become associated with these
    receptors. A dose- and time-dependent association among AMPA receptors,
    the focal adhesion kinase pp125(FAK), the phosphatidylinositol-3 kinase
    and paxillin was found. These results extend the concept of the
    transducisome to AMPA receptors and provide a framework in which a
    plausible control of the cytoskeletal network by glutamate is taking
    place, most possibly through AMPA receptors. (C) 2004 Wiley-Liss, Inc.

 AB Objective To investigate the views of school pupils on sexual violence
    and on the risk of HIV infection and AIDS and their experiences of
    sexual violence.
    Design National cross sectional study.
    Setting 5162 classes in 1418 South African schools.
    Participants 269 705 pupils aged 10-19 years in grades 6-11.
    Main outcome measure Answers to questions about sexual violence and
    about the risk of HIV infection and AIDS.
    Results Misconceptions about: sexual violence were common among both
    sexes, but more females held views that would put them at high risk of
    HIV infection. One third of the respondents thought they might be HIV
    positive. This was associated with misconceptions about sexual violence
    and about the risk of HIV infection and AIDS. Around 11% of males and
    4% of females claimed to have forced someone else to have sex; 66% of
    these males and 71% of these females had themselves been forced to have
    sex. A history of forced sex was a powerful determinant of views on
    sexual violence and risk of HIV infection.
    Conclusions The views of South African youth on sexual violence and on
    the risk of HIV infection and AIDS were compatible with acceptance of
    sexual coercion and "adaptive" attitudes to survival in a violent
    society. Views differed little between the sexes.

 AB Monthly volumes of capture of Lutjanus peru and Lutjanus guttatus from
    the coast of Guerrero, Mexico, were analyzed considering eight annual
    cycles. Time-series, auto correlation, and cross-correlation analysis
    showed that monthly abundance of populations display unsystematic
    variations. The FiSAT software was used to obtain the recruitment
    patterns of both species, using length-frequency data. Our results
    support the hypothesis that temporal phase-shifts in reproductive
    events, hence recruitment, explain the coexistence of these species.
    The outcome of this mechanism is a temporal succession of specific
    recruit abundance off the coasts of Guerrero, Mexico. The uncoupling of
    the recruitment events between these species, induces a separation of
    recruits: therefore, the intake of a particular set of preys could take
    place at different times.

 ID MACHINE VISION; FRUIT
 AB Rhizopus stolonifer causes significant postharvest losses and about 80%
    of the total loss in pre-packaged and loose tomato fruits were due
    Alternaria rot and Rhizopus rot. The feasibility of using near infrared
    spectroscopy (NIR) for Rhizopus stolonifer conidia detection was
    studied. Visible and near infrared spectra were acquired before and
    after inoculating 200 tomatoes in the laboratory. The spectral data
    were studied using discriminant analysis, and Rhizopus stolonifer
    conidia were detected with an accuracy of 78%. A test set of 200
    tomatoes was used for testing the algorithm, measuring the fruits only
    once. Spore-free and infected tomatoes were classified with an accuracy
    of 81 and 75%, respectively, and 96% of the infected tomatoes were
    properly detected by a neural network method. (C) 2004 Silsoe Research

 TI Rates of sediment recycling beneath the Acapulco trench: Constraints
    from (U-Th)/He thermochronology
 SO JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH

 AB [1] The Sierra Madre del Sur mountain range is an uplifted forearc
    associated with the subduction of the Cocos plate along the Acapulco
    trench beneath mainland southern Mexico. The shallow subduction angle,
    the truncation of geologic features along the modern Acapulco trench,
    and direct seismic and drill hole observations in the trench through
    deep sea drilling data suggest that subduction erosion is an important
    process during the evolution of this margin. Turbidites derived from
    the uplifted forearc are the predominant sedimentary input into this
    trench, while pelagic sediments are subordinate. Apatite (U-Th)/He ages
    were obtained on 23 samples from two transects across the Sierra Madre
    del Sur ( Acapulco and Puerto Escondido) and reveal slow cooling during
    the Miocene. (U-Th)/He ages range between similar to 25 and 8 Ma and
    correlate inversely with elevation. Long-term erosional exhumation
    rates inferred from these ages range from 0.11 to 0.33 km/m.y., with
    higher rates in the range core, and suggest that the Sierra Madre del
    Sur has been a slowly decaying mountain range, since at least the early
    Miocene. Apparent Miocene-Pliocene sedimentation ("preservation'')
    rates in the Acapulco trench derived from Deep Sea Drilling Project
    data are about an order of magnitude smaller than the Miocene forearc
    erosion rates estimated from (U-Th)/He ages, suggesting that the
    terrigenous input to the trench was almost entirely recycled via
    subduction erosion, at least during the Miocene. The Miocene subducted
    flux per unit length of the margin is about 30 km(3)/(km m.y.), or a
    subducted volume per unit time of 44 x 10(3) km(3)/m.y., when
    integrated over the length of the trench.

 AB Background. Cardiovascular disorders (CD) are the most frequent cause
    of death in patients on dialysis. CD have been related to increased
    extracellular fluid volume, peritonea] transport type (PTT),
    hypertension, and inflammation. Inflammation is in itself a risk factor
    for mortality. The aim of this Study was to assess the relationship of
    increased extracellular fluid volume, inflammation. and PTT in patients
    on continuous ambulatory peritoneal dialysis (CAPD) and automated
    peritoneal dialysis (APD).
    Methods. A cross-sectional study was carried out with 20 healthy
    controls (C), 21 patients on CAPD, and nine patients on APD. Clinical
    and demographic variables were measured and registered. Peritonea]
    equilibrium test (PET) was done. Blood volume (BV), total body water
    (TBW), inferior vena cava diameter during inspiration (IVCDi) and
    expiration (IVCDe), serum albumin, and serum C-reactive protein (CRP)
    were measured.
    Results. All patients on peritoneal dialysis (PD) had at least one sign
    or symptom of increased extracellular fluid volume, hypertension being
    the most common. Patients also had higher TBW (C, 60.7 +/- 7.2; APD,
    62.6 +/- 8.7; CAPD, 66.1 +/- 8.3, as percentage of body weight, p <
    0.02), higher BV (C, 7.9 +/- 1.6; APD, 9.8 +/- 2.3: CAPD, 9.6 +/- 2.3,
    as percentage of body weight, 1) < 0.02), higher DIVCi (C, 2.9 +/- 1.2;
    APD, 4.6 +/- 2.5; CAPD, 4.5 +/- 2.4 mm/m(2) BSA, p < 0.02), and higher
    DIVCe (C, 6.2 +/- 1.7; APD, 8.3 +/- 3.4; CAPD, 8.0 +/- 2.8 mm/m(2) BSA,
    p < 0.05). PD patients also had hypoalbuminemia and higher CRP levels.
    There was significant positive correlation between CRP and DIVCi (r =
    0.43, p < 0.05) and IVCe (r = 0.45, p < 0.05) and between serum albumin
    and creatinine dialysate-to-plasma ratio (D/P Cr, r = 0.57, P < 0.01).
    Serum albumin and CRP were negatively correlated (r = -0.54, p < 0.02).
    Conclusions. Patients on PD have increased extracellular fluid volume
    as compared with healthy controls. Hyperhydration is related to
    inflammation and to higher peritoneal transport types. (C) 2004 IMSS.

 AB This work describes stage by stage the biostratigraphy of the Middle to
    Late Permian in Mexico and Guatemala. Roadian deposits are very poorly
    represented, as a consequence of tectonic movements at the end of the
    Kungurian/Leonardian stage. In fact Middle and Late Permian deposits
    are almost completely lacking in South Mexico and the whole Latin
    America, due to a probable climatic barrier. The main data concern the
    Las Delicias sequences from Coahuila, North Mexico, and the Mixteca
    Terrane, South central Mexico, with some precisions on the
    Wordian-Capitanian from Los Hornos Puebla) and from Olinald, Guerrero,
    respectively with the discoveries of Parafusulina sellardsi and
    Polydiexodina capitanensis. New data are provided on Capitanian
    mudmounds from Olinald. A hypothetical reconstruction of the different
    terranes of Mexico at the Pangea stage, is finally presented. (C) 2003

 TI Major and trace element geochemistry and Ar-40/Ar-39 geochronology of
    Laramide plutonic rocks associated with gold-bearing Fe skarn deposits
    in Guerrero state, southern Mexico
 SO JOURNAL OF SOUTH AMERICAN EARTH SCIENCES
 LA English
 DT Article
 DE Fe skarn; gold; granitoids; guerrero; Laramide; southern Mexico
 ID CORDILLERA; TERRANES; ARC
 AB Fe-Au skarn deposits related to intrusive centers, mostly of
    granodioritic composition, are widespread in southern Mexico's Guerrero
    state. These intrusive rocks are largely associated with the
    NW-SE-oriented Laramide magmatic belt that extends across most of
    western Mexico. The geochemical composition and ages of representative
    rocks from the Mezcala mining district in central Guerrero are studied
    to evaluate the petrogenetic aspects of the ore-related magmas. Some
    major and trace elements display nearly linear silica variation trends,
    which suggest a possible comagmatic origin. However, other elements
    have scattered distributions, possibly due to irregular mantle-to-crust
    magma mixing ratios, heterogeneities in the composition of the
    assimilated crustal material, or modifications during the emplacement
    or postemplacement processes. Major element chemistry indicates
    calc-alkalic metaluminous compositions, whereas trace element data
    suggest a volcanic arc tectonic setting, confirming that these rocks
    evolved from magmas generated above a subduction zone. Compared with
    the Laramide granites from the northern part of the belt in
    northwestern Mexico, which intruded a crust underlain by Proterozoic
    North American rocks, the studied samples are similar but relatively
    low in Nb and high in Sr, the middle rare earth elements (REE), P, and
    Zr. They also display minor Ti enrichments and a moderate depletion in
    the heavy REE. These characteristics may indicate a source of basaltic
    composition. New Ar-40/Ar-39 dating of granodiorites and dacite
    porphyries shows a north-to-south age progression from 66.2 +/- 0.8 Ma
    in the northern part of the belt to 62.2 +/- 0.7 Ma in the south.
    Moreover, the argon dates identify a younger postorogenic igneous event
    35-30 Ma ago. This event is poorly documented and may have occurred
    after the extinction of the Laramide arc and prior to the mid-Tertiary
    Sierra Madre Occidental ignimbrite flare-up. On the basis of limited
    geochemical data, these rocks appear to be depleted in P2O5 and Sr and
    enriched in U relative to the studied Laramide granites. A Fe skarn
    deposit located in Buena Vista de Cuellar, in the north central part of
    Guerrero, suggests that this magmatic pulse took place after the ore
    development of the Mezcala district. (C) 2003 Elsevier Ltd. All rights

 AB The acaricidal mycopathogen Hirsutella thompsonii has been found to
    secrete metabolites that are active against female Tetranychus urticae.
    Specifically, the rose-colored exudate produced on sporulating cultures
    of Mexican HtM120I strain sterilized female spider mites in a
    dose-dependent fashion. Topical application of the exudate resulted in
    a 100% reduction in mite fecundity over the initial six days of
    experimentation. Depending upon the exudate dosage, mites partially
    recovered within 3 and 6 d post-treatment and produced a limited number
    of eggs. The spider mite active HtM120I exudate contained less
    detectable HtA toxin than the HtM120I broth filtrate, and it was
    innocuous when injected into the greater wax moth Galleria mellonella
    L. larvae. Broth filtrates of HtM120I cultures, although toxic to
    assayed G. mellonella larvae, did not inhibit mite oviposition to the
    degree or duration of the exudate preparations. These findings suggest
    that the factor responsible for suppressing oviposition in female
    spider mites is linked to the sporulation process and is distinct from
    the well-characterized HtA produced by vegetative cells.

 AB Seeds from two commercial bean varieties were cooked and stored for
    different times and analysed for chemical composition and in vitro
    starch digestibility. Parallel portions of cooked seeds were dried at
    55 degreesC, milled and stored as flours. In general, protein and ash
    contents in both samples did not change with storage time, but
    statistical differences were shown between the two varieties (p <
    0.05). Available starch (AS) contents in flours from the 'negro'
    variety did not change (p < 0.05) with storage time and, in general,
    were higher than in 'flor de mayo' samples, whose AS levels decreased
    during storage. The lower AS in 'flor de mayo' flour could be the
    consequence of formation of resistant starch due to retrogradation.
    Samples of whole 'negro' seeds did not show differences in AS content
    at 0, 24 and 48 h of storage compared with the corresponding flours,
    but at 72 and 96 h the AS increased in the whole samples. 'Flor de
    mayo' showed a similar pattern in flour and whole samples, with
    slightly higher values in the whole seeds. In general, total resistant
    starch (RS) content in the two varieties was higher in the flours than
    in 'whole' seeds, a fact that is not easy to explain at present.
    'Negro' flour presented an RS content around 65.0 g kg(-1), and
    approximately 55.0 g kg(-1) was recorded in 'flor de mayo', with slight
    changes when storage time increased. Whole 'flor de mayo' showed
    significant levels of the retrograded portion of resistant starch
    (RRS), which did not change with storage time (p < 0.05). However,
    values were lower than in the flours. A pattern similar to that of the
    'negro' variety was obtained for 'flor de mayo', since the flour
    exhibited higher amounts of RRS; however, in this variety, the RRS
    content in 'whole' samples decreased after prolonged storage. Flours
    presented higher amylolysis rates than whole samples, and the ease of
    digestion increased with storage time. (C) 2003 Society of Chemical

 AB New identifications of radiolaria and conodonts allow clarifying the
    biostratigraphy of the Pennsylvanian and Permian deposits in San
    Salvador Patlanoaya (Puebla State, Mexico). The radiolaria are
    sometimes relatively common in the series, but weakly diversified and
    endemic. Among the conodonts, Streptognathodus bellus is characteristic
    of the Late 'Virgilian' sensu Baars, probably coeval with the Early
    Wolfcampian sensu Thompson or Wilde, the Bursumian of Ross & Ross or
    the Orenburgian-Asselian stage or substage of Russia (sensu Davydov).
    San Salvador Patlanoaya is a key-section for the Pennsylvanian-Permian
    boundary in Mexico. (C) 2002 Academie des sciences / Editions

 TI Apparent density in a vertisol with different agrosystems
 SO INTERCIENCIA

 DT Article
 ID SOIL; NIGERIA; WATER
 AB The physical properties of soils have received attention for their role
    in maintaining a sustainable sugarcane production. Under this scheme,
    the present study was focused on evaluating the apparent density (DAp)
    of a vertisol soil in sugarcane, pasture and medium perennial
    rainforest agro-ecosystems was evaluated. Soil samples were taken from
    the space between furrows of a sugarcane plantation that are used as
    trails for trucks, trails for crop-lifters, or never affected by
    machinery; 9 samples were taken at random per crop cycle. Pasture and
    forest soils were sampled at random with 6 repetitions. DAp at 0-10cm
    in depth was determined by the cylinder method. Eleven treatments were
    analyzed by a completely randomized design and orthogonal contrasts.
    Soils cultivated with sugarcane suffer from higher compaction during
    the harvest, irrespective of the crop cycle. Truck passage results, due
    to their heavier weight, in more compaction than crop-lifters. DAp
    increases with the number of crop cycles. The DAp, averaged over the
    various cane cycles, did not reach the critical values for the roots
    (1.60g cm(-3)); however, the DAp observed in sugarcane agro-ecosystems
    surpassed that of pasture and forest soils. The DAp observed in pasture
    agro-ecosystems is,intermediate between the forest and sugarcane, which
    suggests that soil cracking during the dry season, as well as their
    recent origin, might give the former a higher dampening capacity. This
    might also explain why the DAp has only changed 20% in relation to
    rainforests during the last 20 years.

 AB During tissue invasion, Entamoeba histolytica trophozoites interact
    with endothelial cells and extracellular matrix (ECM) proteins such as
    fibronectin (FN), collagen, and laminin. It has been demonstrated that
    trophozoites interact with FN through a beta1 integrin-like FN receptor
    (beta1EhFNR), activating tyrosine kinases. In order to characterize the
    signaling process triggered by the amoebic receptor, activation, and
    association of tyrosine kinases and structural proteins were
    determinated. As a result of FN binding by the beta1EhFNR, the receptor
    itself, FAK, and paxillin were phosphorylated in tyrosine.
    Co-immunoprecipitation experiments showed that a multimolecular
    signaling complex was formed by the amoebic FN receptor, FAK, paxillin,
    and vinculin. These results strongly suggest that a signaling pathway,
    similar to the one used in mammalian cells, is activated when E
    histolytica trophozoites adhere to FN. (C) 2003 Elsevier Science (USA).

 AB The purpose of this study was to examine the uptake and distribution of
    ions in three grain legume species for potential use in and zones.
    Tepary bean (Phaseolus acutifolius A. Gray), cowpea (Vigna unguiculata
    L. Walp.), and wild bean "frijolillo" (Phaseolus filiformis Bent) were
    grown during a period of 14 d in a nutrient solution salinized with 80
    mmol L-1 NaCl. Plant height, leaf number, and leaf area of the saline
    treated plants were all low because of salinity. The dry weight (DW) of
    the roots, stems, and leaves of cowpea and "frijolillo" was
    significantly lower when the plants were subjected to the saline
    treatment, while the DW of the stems and leaves of the tepary bean
    plants treated with NaCl was close to that of the control plants (0
    mmol L-1 NaCl). Root DW was significantly higher under salinity
    conditions only in tepary bean. The net uptake rate (NUR) and net
    transport rate (NTR) of Ca2+, Mg2+, and K+ in cowpea and "frijolillo"
    shoots were lower in the saline treated plants than in the control (0
    mmol L-1 NaCl), while tepary bean subjected to the salinity treatment
    displayed higher cation net uptake rate and transport. The NTR / NUR
    ratio of Na+ in tepary bean, "frijolillo," and cowpea treated with NaCl
    were 0.07, 0.70 and 0.72, respectively, indicating that Na+ transport
    to the shoots was in the following order: cowpea > "frijolillo" >
    tepary bean. Na+ distribution to roots, stems, and petioles was higher
    than the DW distribution to the same organs of the saline-treated
    plants only for tepary bean, while the Na+ distribution was lower than
    the DW distribution to leaves. These facts indicate that Na+ ion easily
    move to the leaves in cowpea, while in tepary bean and "frijolillo,"
    Na+ mobility is restricted in order to prevent Na+ accumulation in
    leaves, and is achieved through the higher capacity of the stem and
    petiole to hold Na+. In the cowpea and "frijolillo" plants treated with
    NaCl, the uptake and transport of Ca2+ and Mg2+ were significantly
    lower, while in the tepary bean plants these rates were not affected by
    the saline treatment that exerted a negligible adverse effect on plant
    growth. The higher Ca2+ and Mg2+ uptake in tepary bean could be caused
    either by the higher Ca2+ and Mg2+ absorption efficiency or by the
    higher Ca2+ and Mg2+ uptake and transport required to neutralize excess
    Cl- in the cells.

 AB The Acatlan Complex of southern Mexico is linked to the evolution of
    the Appalachian-Caledonian chains and records C rents related to the
    Taconian, Acadian, and Alleghanian orogenies of northeastern North
    America. Mafic eclogites and garnet amphibolites from two selected
    localities are used to partially reconstruct the tectonometa-morphic
    evolution of this complex. Eclogites contain garnet (almandine) + Ca-Na
    pyroxene + phengitic mica + zoisite-clinozoisite + quartz +/- Ca-Na
    amphibole (barroisite, katophorite) +/- albitic plagioclase +/- rutile.
    Phase and textural relationships, thermobarometric determinations, and
    available radiometric ages indicate that eclogite-facies metamorphism
    took place during the Ordovician at temperatures around 560 +/-
    60degreesC and pressures between 11 and 15 kbar (1 kbar = 100 MPa).
    Eclogites underwent widespread retrogression to epidote-amphibolite
    then greenschist facies during exhumation, most probably during
    Devonian times. Epidote-amphibolite facies include the critical
    assemblage calcic pyroxene + calcic amphibole (magnesiohornblende and
    pargasite) + muscovite + garnet + plagioclase + epidote +/- quartz.
    whereas greenschist facies is defined by the assemblage actinolite +
    albitic plagioclase + epidote + chlorite. Thermobarometric data suggest
    that retrogression occurred at temperatures between 510 +/- 20degreesC
    and 300 +/- 25degreesC and pressures ranging from 6 to 3.5 kbar, The
    obtained P-T (pressure-temperature) path suggest that the Acatlan
    Complex evolved in a more complex continental collisional setting.
    including intraoceanic arcs, than shown in previously proposed models.

 AB Carbonate microfossils Petschoria (?), Kettnerammina, Kamaena, and
    Tolypammina (?) allow to biostratigraphically date the base of the
    sedimentary cover in San Salvador Patlanoaya (Puebla State, Mexico).
    They are indicative of the former Tournaisian, i.e. the Latest Devonian
    (Strunian) and the Earliest Mississippian Kinderhookian (= Hastarian).
    Deposits of this period are very poorly known in Mexico, and appear to
    be confined to a rift affecting only Patlanoaya, some areas of the
    Sonora and Chihuahua states (Mexico) and the Pedregosa Basin (New
    Mexico, USA). This rift is connected with the Rheic Ocean that opens,
    whereas the Antler Ocean is probably entirely closed in this period, as
    confirmed by the microfossil migration ways. (C) 2002 Academie des

 AB Jalapeno chilli is a variety grown extensively in Mexico consumed by
    almost all the population. It has a high processing demand and proper
    sorting is required before filling or canning. A sorter that classifies
    chilli by three different width sizes was built. The conveyor used baby
    suckers to align each chilli during sensing. Chilli width was
    determined by means of a photodiode scanner, which detected the
    incoming radiation sent by a laser line generator. Chillies presenting
    necrosis were detected with a radiometer and removed to increase
    product quality. The accuracy on the necrosis detection and width
    classification was of 96.3 and 87%, respectively. (C) 2002 Silsoe

 TI Perianal actinomycetoma experience of 20 cases
 SO INTERNATIONAL JOURNAL OF DERMATOLOGY
 LA English
 DT Article
 ID MYCETOMA
 AB Background Actinomycetoma is a chronic infection resulting from aerobic
    Actinomycetes . The major agents are Nocardia brasiliensis,
    Actinomadura madurae , and Streptomyces somaliensis . The most frequent
    topographies are the lower and upper limbs. The prognosis of this
    disease is determined by several factors, such as etiologic agent,
    clinical topography, and depth of disease (degree of involvement,
    visceral, and bone affection). The purpose of this paper was to present
    our experience with actinomycetoma of the perianal region.
    Methods This study comprises 20 cases of perianal actinomycetoma, all
    of which were clinically and microbiologically proven by direct
    examinations, cultures, and biopsies. Clinical responses to the two
    principal treatment regimes used [combination of
    trimethoprim-sulfamethoxazole (TMS/SMX) and diaminodiphenylsulfone
    (DDS) or amikacine plus TMS/SMX] are reported.
    Results Most of the cases were male (17/20, 85%), the mean age was 42.1
    years, and the farmers predominated (90%). The principal etiologic
    agent isolated was N. brasiliensis (85%).
    Conclusions Perianal actinomycetoma is a rare entity. Differential
    diagnosis with anal sinuses, hydroadenitis, and cutaneous tuberculosis
    must be made in endemic areas by performing mycologic tests and
    biopsies. Treatment depends on the etiologic agent involved and the
    patient's condition.

 ID DIET
 AB Stomach contents analysis was used to describe quantitatively the
    feeding habits of Lutjanus guttatus. A total of 239 organisms with fork
    lengths between 12 and 55 cm were collected monthly from February 1993
    to January 1995 in the coast of Guerrero. This species consumed a wide
    variety of prey organisms, mainly small fishes (index of relative
    importance, IIR = 67.46%) of the families Engraulidae, Clupcidae and
    Bregmacerotidae. Crustaceans, represented by Reptantia, Natantia and
    Stomatopoda, were consumed less (IIR = 30.94%). The composition of the
    diet varied as a function of the fish size. Seasonal and sexual
    differences in the diet were not significant.

 AB Five broccoli varieties were grown under and conditions in order to
    compare yield, head quality and precocity. The highest yield was
    obtained in Ryokurei with 6.8 ton/ha which was achieved by a
    significant increase of head fresh weight and compactness in comparison
    with other varieties. However, Ryokurei seeds art, produced in Japan,
    whereby seed availability in local markets is an obstacle which must be
    overcome. The Galleon variety manifested the highest precocity among
    evaluated varieties and its head harvest began 7 days before compared
    to other varieties, and only needed two harvests to accumulate 6
    ton/ha, while Ryokurei needed four harvests to produce 6.8 ton/ha. From
    these results, the Galleon variety is recommended to grow in and areas
    because its precocity allows it to save water and the seed is easily
    found in local markets.

 ID FUSARIUM
 AB Fusarium oxysporum was detected on the majority of the tomato
    plantations in the state of Sinaloa, Mexico, reducing yields to 50%.
    Fusarium rot and Rhizopus rot appeared in storage rooms producing high
    postharvest losses. Actually, it takes a day to determine whether the
    sample is infected, by isolating fungal spores on nutrient agar plates.
    Laboratory equipment capable of detecting spores quickly and with high
    sensitivity is required in packing houses to increase tomato quality
    and reduce postharvest losses. Visible and near infrared (NIR) spectra
    were obtained before and after inoculating tomatoes with Fusarium
    oxysporum and Rhizopus stolonifer conidia. Spectral signatures in the
    frequency domain were analysed using discriminant analysis and models
    capable of detecting spore-free and inoculated tomatoes were obtained.
    Tomatoes containing Fusarium oxysporum and Rhizopus stolonifer conidia
    on their surfaces were detected with high success rates and could also
    be distinguished accurately. (C) 2002 Silsoe Research Institute.

 DE arthralgia; joint diseases; giardiasis; Giardia lamblia; children
 ID REACTIVE ARTHRITIS; LAMBLIA; DIAGNOSIS
 AB Background. Giardiasis is the most common intestinal parasitosis in
    Mexico. Usual symptoms of the acute infection are diarrhea, abdominal
    pain, nausea, and weight loss. Children are more frequently affected
    than adults. Various extra-intestinal manifestations have been
    reported, among which are arthritis and arthralgia.
    Methods. A series of 10 children with arthralgia and cysts of Giardia
    lamblia in feces seen during 13 years of private practice were
    presented. Ages ranged between 5 and 11 years, and 70% of the children
    are males.
    Results. The joints involved in all cases were the knee and the ankle.
    No joint flogosis or changes in local temperature were observed. Other
    associated symptoms were abdominal pain (100%), abdominal distension
    (70%), flatulence (50%), less consistent stools (50%), anemia (30%),
    and increased erythrocyte sedimentation rate (60%). C-reactive protein
    and rheumatoid factor were negative in all cases. Arthralgia
    disappeared after treatment with metronidazole when coproparasitoscopic
    analyses were negative.
    Conclusions. Arthralgia associated with giardiasis in children is a
    rare entity, relatively benign, and leaves no sequelae. (C) 2001 IMSS.

    Pennsylvanian oceanizations are briefly described, and the work is
    mainly concerned with the Early Permian (Wolfcampian-Leonardian),
    fossiliferous in the whole country. Moreover the Middle- and Late
    Permian are very badly exposed in Mexico. A paleobiogeographic
    reconstruction of Mexican Upper Paleozoic suspect terranes is also

 AB Two bioassays were administered to determine the dose-lethality
    response of Varroa jacobsoni Oudemans and the honey bee, Apis mellifera
    L., to amitraz, flumethrin and fluvalinate. The first bioassay method
    was spraying by means of the Potter-Bourgerjon's tower. The results are
    expressed in mean lethal concentrations (LC50). The second method was
    topical application by means of microsyringe and manual applicator. The
    results are expressed in mean lethal doses (LD50). Both LC50 and LD50
    values were considerably higher in honey bees than in varroa mites,
    showing that a wide margin of safety exists between effective doses
    against mites and harmful doses for honey bees. Both methods gave
    similar confidence intervals; they showed a comparable sensitivity to
    changes in dose or concentration of pesticides.

 AB The composite Guerrero Terrane of western Mexico records much of the
    magmatic evolution of southwestern North America during Late Mesozoic
    time. The Guerrero includes three distinctive subterranes characterized
    by unique stratigraphic records, structural evolutions, and geochemical
    and isotopic features that strongly suggest they evolved independently.
    The eastern Teloloapan Subterrane represents an evolved intra-oceanic
    island are of Hauterivian to Cenomanian age, which includes a high-K
    calc-alkaline magmatic suite. The central Arcelia-Palmar Chico
    Subterrane represents a primitive island are-marginal basin system of
    Albian to Cenomanian age, consisting of an oceanic suite and a
    tholeiitic are suite. The western Zihuatanejo-Huetamo Subterrane
    comprises three components that represent an evolved island
    are-marginal basin-subduction complex system of Late Jurassic (?)
    -Early Cretaceous age built on a previously deformed basement. The
    Zihuatanejo Sequence includes a thick high-K calc-alkaline magmatic
    suite. The Las Ollas Complex consists of tectonic slices containing
    exotic blocks of are affinity affected by high-pressure/low-temperature
    metamorphism included in a sheared matrix. The Huetamo Sequence
    consists mainly of volcanic-are derived sedimentary rocks, including
    large pebbles of tholeiitic, calc-alkaline, and shoshonitic lavas.
    These sequences an unconformably underlain by the Arteaga Complex,
    which represents the subvolcanic basement. On the basis of available
    geology, geochemistry, geochronology, and isotopic data, we suggest
    that Late Mesozoic volcanism along the western margin of southern North
    America developed in broadly contemporaneous but different
    intra-oceanic island arcs that constitute a complex fossil arc-trench
    system similar to the present-day western Pacific island are system.

 AB Volcanic and interbedded volcaniclastic rocks of the lower Cretaceous
    island-arc series of the Teloloapan Terrane in southern Mexico contain
    metamorphic assemblages characteristic of the zeolite,
    prehnite-pumpellyite and lower greenschist facies produced by burial
    metamorphism prior to its accretion to nuclear Mexico. Distribution of
    secondary assemblages throughout the stratigraphic succession, together
    with the chemical evolution of metamorphic minerals, reveals a
    depth-controlled metamorphic zonation characterized by the presence of
    the diagnostic assemblages laumontite + pumpellyite + epidote and
    laumontite + celadonite + pumpellyite +/- epidote (zeolite facies)
    followed downward by assemblages containing prehnite + pumpellyite +/-
    white mica (prehnite-pumpellyite facies) and finally by the presence of
    the assemblages pumpellyite + actinolite + epidote and epidote +
    actinolite (greenschist facies). Analysis of assemblages in the
    Al-Fe3+-FM-K system, reveals that facies boundaries are discontinuous,
    involving the disappearance of at least one phase and the appearance
    and/or extension of the field of equilibrium of other diagnostic
    minerals and assemblages. Application of empirically based
    thermobarometers, phase equilibria, mineral chemistry, and petrogenetic
    grids indicates that the P-T conditions of metamorphism ranged from 175
    to 342 degreesC and P < 3 kbar. The data further indicate high
    geothermal gradients of about <similar to>55 degreesC km(-1).
    Seawater-derived fluids were characterized by high a(K) high f(O2) and
    low X-CO2. (C) 2000 Elsevier Science B.V. All rights reserved.

 ID SHEAR; SENSE
 AB The Teloloapan volcanic are in SW Mexico represents the eastern most
    unit of the Guerrero Terrane. It is overthrust by the Arcelia volcanic
    unit and is thrust over the Guerrero-Morelos carbonate platform. These
    major structures result from two closely related tectonic events:
    first, an eastward verging, ductile deformation (D1) characterized by
    an axial-plane schistosity (S1) supporting an E-W trending mineral
    stretching lineation (L1) and associated with synschistose isoclinal,
    curvilinear folds (F1). Numerous kinematic indicators such as
    asymmetrical pressure-shadows, porphyroclast systems, and micro-shear
    bands (S-C structures) indicate a top-to-the-east shear along LI. This
    first deformation was followed by another ductile event (D2) that
    produced a crenulation cleavage (S2) associated with westward
    overturned folds (F2), hence showing that the vergence of D2 is
    opposite to that of D1. Regionally, both D1 and D2 deformations have
    been identified east and west of the Teloloapan unit, in the Arcelia
    volcanic rocks as well as in the Mexcala flysch of Late Cretaceous age
    overlying the Guerrero-Morelos platform. This implies that all three
    units were deformed and thrust simultaneously, during the Late
    Cretaceous or Paleocene, prior to the deposition of the overlying,
    undeformed Eocene red beds of the Balsas group. (C) 2000 Elsevier

 AB The entomopathogenic fungi Metarhizium anisopliae (Metschnikoff)
    Sorokin and Beauveria bassiana (Balsamo) Vuillemin and the bethylid
    parasitoid Prorops nasuta Waterston are natural enemies of the coffee
    berry borer, Hypothenemus hampei (Ferrari), and are considered valuable
    biocontrol agents in the coffee-growing regions of Central and South
    America. Laboratory evaluations were made on the impact of three
    isolates of each fungus on adult P, nasuta. These isolates were
    selected because of their high virulence toward H, hampei in previous
    studies. B, bassiana isolate Bb25 and M. anisopliae isolate Ma4 caused
    the lowest infection levels in P. nasuta with LC50 values of 8.31 x
    10(6) and 4.08 X 10(6) spores per milliliter, respectively, Ly direct
    inoculation. Spore suspensions of each of these isolates were applied
    to coffee berry borer infested coffee berries. P. nasuta adult females
    were allowed to search and parasitize hosts within the treated berries.
    Despite the high virulence of these fungi to P. nasuta, neither
    pathogen significantly affected the predatory or parasitic capacity of
    P, nasuta, indicating that these isolates may he compatible with the
    action of the parasitoid under field conditions provided that pathogen
    applications and parasitoid liberations are timed not to coincide.

 TI Melanges in southern Mexico: geochemistry and metamorphism of Las Ollas
    complex (Guerrero terrane)
 SO CANADIAN JOURNAL OF EARTH SCIENCES

 DT Article
 ID WESTERN-CORDILLERA; PHYLLOSILICATES; GEOTHERMOMETER; CALIFORNIA;
    MINERALS; AMERICA
 AB Las Ollas complex (LOC) is a subduction complex spatially associated
    with the early Cretaceous Zihuatanejo-Huetamo subterrane (Guerrero
    terrane) in southern Mexico. LOC tectonic melanges compose of a stack
    of east-dipping, west-vergent tectonic sheets containing blocks of
    metabasalt, metadolerite, metagabbro, ultramafics, volcaniclastics,
    quartz-rich sandstone, and chert enveloped in a highly sheared clastic
    or serpentinitic matrix. Most igneous and igneous-derived metamorphic
    blocks show geochemical and isotopic features typical of island-arc
    tholeiitic suites: (i) low TiO2 (0.13 to 0.91%) and Zr (5 to 57 ppm)
    contents; (ii) high (LFSE/HFSE)(N) ratios; low La-N/Yb-N (0.5 to 4)
    values; and, high epsilon(Nd)((T)) (+7.9 to +8.0) ratios.
    Petrographical and mineral chemistry evidence indicates that blocks
    underwent early recrystallization under high pressure and low
    temperature (HP-LT), blueschist facies conditions during subduction.
    Typical assemblages include blue (sodic through calco-sodic to Na-rich
    calcic) amphibole + lawsonite +/- tremolite +/- Mg-chlorite +/- white
    mica +/- albite +/- quartz. Phase relations and chlorite thermometry
    suggest temperatures of about 200 degrees-330 degrees C and pressures
    of 5-7 kbar. It is proposed that sedimentary blocks were generated by
    in situ remobilization and mixing, whereas igneous blocks most probably
    derived from the chemically and isotopically identical Zihuatanejo
    island-arc suite. Our data suggest that LOC represents part of a
    subduction complex formed by eastward-directed subduction related with
    the evolution of the early Cretaceous Zihuatanejo island arc.

    temperatures (25 and 35 degrees C). GCWS starches prepared at 25
    degrees C and with 40 and 60% aqueous ethanol had the lowest cold-water
    solubility. that prepared with 40% aqueous ethanol at 35 degrees C and
    stored at room temperature showed]low tendency to retrogradation, as
    assessed by transmittance. solubility and swelling profiles were
    similar for GCWS starches and the freeze-thaw stability of GCWS
    starches was increased as compared with native starch. The apparent
    viscosity of GCWS banana starches was higher than that of its native
    starch counterpart.

 AB In pepper (Capsicum annuum) under greenhouse conditions. Sap flow
    gauges (Dinamax, Inc.) were used to evaluate the stem heat balance
    (SHB), through an in, situ method for measuring the sap flow rate. The
    SHB technique consists of a heated stem segment with a known and steady
    amount of heat from a thin flexible heater that encircles the stem.
    Measurement of sap flow depends on a thermopile to evaluate radial heat
    loss, and the temperature gradients estimated by thermocouples above
    and below the heater to evaluate vertical conductive heat loss. The
    saline treatments consisted in five levels of electrical conductivity
    (CE) 6.95, 5.68, 4.42, 3.12 and 0.10 dS . m(-1) Transpiration rate (Te)
    measurements, when plants were 71 days old, with average0 cm average
    height and 10 mm average stem diameter. The treatments continued for 22
    days. Values obtained by this method were compared with gravimetric
    values (Tg) for estimation of accuracy, and adjusted using the
    relationship Te and Tg. The RGR (relative growth rate) and NAR (net
    assimilation rate) for the most saline treatments (6.95, 5.68, and 4.42
    dS . m(-1)), were 7.81 x 10(-3), 8.35 x 10(-3) and 12.1 x 10(-3) g .
    g(-1). day(-1) for RGR, and 18.4 x 10(-5), 19.7 x 10(-5), and 29.1 x
    10(-5) g . cm(-2). day(-1) for NAR, respectively. On the other hand,
    the loner saline treatments (3.12 and 0.10 dS . m(-1)) showed RGR
    values of 13.9 x 10(-3) and 18.5 x 10(-3) g . g(-1). day(-1),
    respectively, and NAR values of 33.6 x 10(-5) and 44.7 x 10(-5) g .
    cm(-2). day(-1), respectively. Te by SHB values in the 0.10 dS m(-1)
    treatment were overestimated by 18.8% and Te in 5.68 and 3.12 dS m(-1)
    treatments were underestimated by 11 and 22%, respectively. The
    treatments 6.95 and 4.42 dS m(-1) showed high correlation with
    gravimetric data, underestimated in 1 and 2.6%, respectively. The
    transpiration by SHB was adjusted using a linear relationship. The
    maximum Te was observed in treatment 0.10 dS . m(-1), with 80 g . h(-1)
    which was obtained at midday; the transpiration rate in the other
    treatments decreased according to the salt content of the irrigation
    water.

    the enthalpy changes in both starches were nor different. Both starches
    showed A-type diffraction pattern. until now not reported for banana
    starches. Light microscopy revealed some structural characteristics of
    banana starches as shape and size and eccentric birefringence was
    observed under polarized light. The iodine-stained differed in their
    blue color intensity. The viscosity profiles of both samples evaluated
    with the Rapid Visco Analyzer (RVA) were similar, and the
    gelatinization temperatures agree with those obtained by DSC. The
    pastes formed from banana starches in general were opaque and the
    storage temperature had a slight effect on clarity.

 AB A new sprayable microgranule formulation of Bacillus thuringiensis
    subsp. kumomatoensis (strain C-9) was evaluated for the control of the
    Mexican bean beetle Epilachna varivestis Mulsant. Strain C-9 was
    isolated from dead E. varivestis in a Phaseolus vulgaris L. field in
    Durango, Mexico. A spore and crystal complex of the C-9 strain were
    active against E. varivestis larvae in bioassays using treated bean
    plants (LC50 of 642 mu g/ml), and against Trichoplusia ni (Hubner)
    larvae using artificial diets (LC50 of 219 mu g/ml). The sprayable
    powder (microgranule formulation), consisting of cornstarch (CS),
    nixtamalized corn flour (NCF), vegetable oil, powdered sugar,
    2-propanol, malachite green, and formaldehyde, was prepared using a
    spray-dry process. Shelf life of formulated B. thuringiensis maintained
    over 90% of its original activity after 24 months of storage. A field
    test demonstrated that treatments of formulated B. thuringiensis
    controlled E. varivestis significantly better than treatments with
    unformulated B. thuringiensis. This study demonstrated that B.
    thuringiensis can potentially be formulated by spray drying, based on

 AB Two varieties of banana green fruit growing in Guerrero, Mexico, were
    used for starch isolation. Chemical analysis and physicochemical and
    functional properties were studied in these starches. The "macho"
    variety presented higher starch yield than "criollo". In general,
    chemical compositions in both starches were similar, except in ash
    content, where the "criollo" variety showed a lower value than "macho".
    The results of freeze-thaw stability suggested that banana starches
    cannot be used in frozen products. Both starches presented similar
    water retention capacity values that increased when temperature
    increased. Solubility profiles showed that at law temperature "criollo"
    had lower solubility than "macho", but at higher temperature an inverse
    behavior was evident; also the solubility increased when temperature
    increased. Behavior similar to that for solubility was obtained in the
    swelling test. The banana starch studies indicate the "macho" and
    "criollo" varieties have different starch structures as evidenced by
    viscosity.

 AB We propose an hybrid approach for structure learning of Bayesian
    networks, in which a computer system and a human expert cooperate to
    search for the best structure. The system builds an initial tree
    structure which is graphically presented to the expert, and then the
    expert can modify this structure according to his knowledge of the
    domain. The system has several tools for aiding the human in this task:
    it allows for graphical editing (adding, deleting, inverting arcs) of
    the network, it shows graphically the correlation between variables,
    and it gives a measure of the quality and complexity for each
    structure. A measure which combines both quality and complexity, that
    we call quality, is defined. We have tested the tool in two domains:
    atmospheric pollution and car insurance, with good results. (C) 1998

 AB Alternative sources from different botanical origin were used for
    starch isolation. Chemical analysis and functional properties were
    studied in amaranth seed and banana fruit starches. Chemical
    composition in both starches was different; banana starch presented
    higher protein, fat and ash levels than that from amaranth. Botanical
    origin of these starches contributes notably in their chemical
    composition. Blue value and lambda max gave information on starch
    components: amaranth starch is classified as waxy type and banana
    starch as normal. Functional properties were evaluated; amaranth starch
    was more soluble than banana starch, but at higher temperatures
    amaranth showed lower swelling values than banana starch. The results
    of freeze-thaw stability suggest that amaranth starch can be used in
    frozen products. Apparent viscosity studies showed that amaranth starch
    paste has higher viscosity than banana starch, but the former starch
    presented higher stability during the 30-min test.

 AB The effect of some fatty acids at different concentration and two
    solubilization procedures on clarity of starch, amylose and amylopectin
    pastes was studied. In general, paste clarity, measured as percentage
    of transmittance (%T), decreased with increasing concentration of fatty
    acids and this effect was different with the starch source. Oleic acid
    showed the lowest %T, and this effect was associated to the
    unsaturation in its structure, which might produce stronger
    intermolecular interactions between the fatty acid and starch chains.
    In contrast, interactions between saturated fatty acids (palmitic and
    stearic) and starch chains might be associated to molecular structure
    of starches more than chain length of fatty acids. Additionally it was
    observed that fatty acid addition before starch gelatinization,
    developed clearer pastes that when fatty acid addition was done after
    gelatinization.

 AB High-performance size-exclusion chromatography (HPSEC), static light
    scattering (SLS) and dynamic light scattering (DLS) techniques were
    used for the structural characterization of amaranth starch,
    solubilized in water by microwave heating in a high-pressure vessel.
    Apparent average molar mass (M-w) gyration radius (R-G), and
    hydrodynamic radius (R-H) values were obtained from Berry and Zimm
    treatment of light-scattering data. When heating time increased from 35
    to 90 sec, the M-w, R-G, and R-H decreased, demonstrating a possible
    polymer degradation due to temperature. Apparent M-r values from HPSEC
    at 35 sec (27 +/- 2 x 10(7) g/mol) and 50 sec (20 +/- 2 x 10(7) g/mol)
    were lower than those determined by SLS (35 sec = 69 x 10(7) g/mol, 50
    sec = 56 x 10(7) g/mol). However, at 70 and 90 sec, the inverse pattern
    was obtained. The fractal dimensions (d(f)') from HPSEC study for
    samples dissolved for 35 (3.26), 50 (3.24), and 70 sec (3.14) are
    characteristic of a particle that has the internal structure of hard
    sphere, and for samples dissolved for 90 sec (2.19), are characteristic
    of a fully swollen, randomly branched macromolecule. From SLS, d(f)'
    decreased with increasing treatment time (d(f)' = 2.44, 2.18, 1.50, and
    1.03 for 35, 50, 70, and 90 sec, respectively). The particle-scattering
    factors and Kratky plots, well-suited for studying the internal
    structure of a macromolecule, showed a sample degradation when
    treatment time increased. Results from DLS showed bimodal distributions
    with differences in the peak locations when treatment time increased.
    The ratio of R-G to R-H (rho) for samples analyzed were between 0.88
    and 1.3; these values are characteristic of a sphere or globular
    structure.

 ID AMYLOSE
 AB Starches from various botanical sources, presenting different
    amylose-amylopectin levels, were solubilized with microwave healing and
    analyzed by high-performance size exclusion chromatography coupled
    online with multi-angle laser light scattering and refractive index
    detectors. The molar mass and gyration radius distributions were
    obtained, Analysis of the particle scattering factors (angular
    dependence of the scattered light) showed small differences in the
    internal structure of the samples solubilized during 35, 50 and 70 s.
    However, the slight differences in the internal structure of samples
    studied were revealed using Kratky plot. Structure degradation was
    found when heating of the sample in the microwave oven increased.
    Structural properties influence the functionality of starches in food
    products.

 AB Inhibition of inflammation by a Taenia solium RNA-peptide (metacestode
    factor, MF) was studied by scanning electron microscopy (SEM). Viable
    (96%) T. solium metacestodes obtained from a naturally infected pig
    were dissected and implanted in treated and control mice, removed at 6
    and 12 days postimplantation (p.i.), and studied by SEM. At day 6,
    metacestodes in control mice showed vigorous inflammation, whereas in
    mice treated with MF they were apparently intact with exiguous
    inflammation. Mice immunized with T. solium metacestode antigens showed
    a moderate inflammation; those treated with both MF and T. solium
    antigens presented scanty inflammation. At day 12, metacestodes
    presented copious inflammation and severe damage to the sucker tissues
    in mice immunized with T. solium; in mice treated with either MF or MF
    and T. solium antigens there was only discrete inflammation. These
    observations illustrate the central role of MF in the inhibition of the
    early events leading to the parasite's destruction by means of an
    inflammatory response.

 SO INTERNATIONAL JOURNAL OF DERMATOLOGY

 DT Article
 AB Background The effect of health education provided by teachers, in
    three primary schools of Guerrero, Mexico, on the prevalence of head
    louse infestation was compared.
    Methods A cross-sectional survey and rapid appraisal methods were
    performed, including a child questionnaire and qualitative data from
    teachers and focus groups of mothers in the same schools.
    Results Nine hundred and forty-four students and 33 teachers were
    interviewed; a focus group discussion with 6-8 mothers per school was
    performed. In the self-diagnosis of pediculosis, the prevalence was 22%
    (range, 18%-33%) with a sensitivity of 68% and a specificity of 86%. In
    one school, 100% of the teachers applied a health program, whereas in
    the other two schools this percentage was only 20%. A child under 9
    years of age who attended a school without information on health was
    3.6 times more likely to have head louse infestation (OR=3.6,
    CI95%=2.1-6) than a child of the same age who attended a school where
    information was given. In older children the effect and potential
    impact were lower. The difference between the two age groups is
    unlikely to be explained by chance (X-2 het=5.7, df=1, p=0.01).
    Conclusions This study emphasizes the potential value of simple, but
    effective, health education provided by school teaching staff through
    liaison with patents in the amelioration of endemic disease.

 AB It has previously been demonstrated that immunization of pigs with a
    crude extract of Taenia solium metacestodes can confer a high level of
    protection against an egg challenge. Furthermore, vaccination of
    infected animals also induces an immune response against the larvae,
    which are either destroyed or rendered non-infectious. To assess the
    efficacy of immunization as a strategy for reducing the prevalence of
    porcine cysticercosis, a field trial of this vaccine was performed in
    an endemic area in the northern region of the Guerrero State, Mexico.
    Random samples of pigs belonging to 17 villages were examined for
    metacestodes by inspection of their tongues. Each animal was immunized
    with a dose of 150 mu g of protein (antigenic extract from Taenia
    solium metacestodes) by the intramuscular route. A prevalence of 2.4%
    of porcine cysticercosis on average was found in these villages at the
    beginning of the trial (62 cysticercotic pigs out of 2650 inspected).
    Six of these villages were selected for the periodic vaccination of new
    random samples of pigs. A statistically significant decline in the
    prevalence of porcine cysticercosis was observed at the end of the
    trial, decreasing from 2.4% at the beginning of vaccination to 0.45% at
    the end of the trial, A reduction of 82% was observed in spite of the
    poor living conditions in these villages, These results are consistent
    with previous data and suggest that it may be possible to turn a
    susceptible pig population into a protected one by systematic
    vaccination.

 AB Subcutaneous implantation of Taenia solium metacestodes in mice induces
    an inflammatory reaction made up mainly of neutrophils and eosinophils
    after 12 days. Administration of a small RNA-peptide (metacestode
    factor, MF) purified from T. solium metacestodes significantly reduces
    the inflammatory site in both size and composition, yielding a very low
    number of eosinophils. The metacestodes implanted in control mice were
    completely destroyed and their remnants were surrounded by an intense
    inflammation predominantly made up of neutrophils and eosinophils. In
    contrast, metacestodes implanted in mice treated with MF showed
    apparently intact suckers, rostellum, hooks, and tegument. Inhibition
    of inflammation around the parasites was also observed in mice
    immunized with T. solium metacestode antigens and inoculated
    simultaneously with MF. Mice immunized only with T. solium metacestode
    antigens produced a granulomatous process around metacestodes that
    destroyed most of the large metacestode structures: suckers, rostellum,
    hooks, and tegument-wall tissues. Furthermore, treatment of mice with
    MF or implanted metacestodes decreased the antibody (P<0.05) and
    cellular responses (P<0.05) to metacestode antigens. The antibody
    response was even lower when both of these treatments were given
    simultaneously. These findings support the idea that MF plays a key
    role in the down-regulation of the host immune response, contributing
    to the parasite's survival.

 AB During November 1993, we traversed by ground and by air the Vizcaino
    Desert, the last redoubt of the peninsular pronghorn (Antilocapra
    americana peninsularis). A total of 29 h of aerial census was performed
    and a total of 1900 km(2) were covered by ground, totalling 400 man
    hours of survey. At present the peninsular pronghorn population
    consists of 175 individuals, and inhabits an area of approximately 5000
    km(2). Because of the impossibility of controlling its activities over
    such an area and because of the present small population size, we
    propose to manage part of the population in semi-captivity at Mesa de
    la Choya island, with the objective of assuring the survival of this
    subspecies, the most endangered mammal in Mexico. (C)1996 Academic

 AB The stomach contents of 50 specimens of the coyote Canis latrans from
    the Vizcaino Desert of northwestern Mexico were analyzed to determine
    predation level of this species upon the endangered population of Baja

 AB Thirty-two cows, averaging 112 DIM, were assigned to four dietary
    treatments: 1) control, 2) Ca salts of fatty acids, 3) nicotinamide,
    and 4) Ca salts of fatty acids blended with nicotinamide during
    manufacture. Preliminary studies showed that nicotinamide survives
    blending with Ca salts of fatty acids during manufacture and that a
    blended mixture of nicotinamide and Ca salts of fatty acids gave
    results similar to those from nicotinamide plus Ca salts of fatty acids
    supplemented separately. Calcium salts of fatty acids increased milk
    fat percentage, decreased milk protein percentage, but had no effect on
    production of milk, FCM, fat, or protein. Nicotinamide increased
    production of milk and protein, decreased fat percentage, but had no
    effect on either production of FCM and protein or percentage of
    protein. Calcium salts of fatty acids increased NEFA in blood, and
    dietary nicotinamide increased concentrations of nicotinamide in blood,
    but glucose and BHBA in blood were unaffected by either dietary
    ingredient. Therefore, in these midlactation cows, the decreased milk
    protein percentage caused by supplemental dietary fat was prevented by
    nicotinamide. Supplementation with only nicotinamide increased total
    production of milk protein.

 DE PROFILES; BREAKWATER; EROSION
 AB Four bathymetric surveys were conducted in front of the breakwater in
    Ensenada, B.C., during 1990 and 1991. Five profiles were projected
    perpendicular to the structure for each survey. A seasonal pattern of
    erosion was found in winter and deposition in, summer. The bathymetry
    shows an accumulation of sediment in the adjacent beach in December,
    and at the base of the deflection during the entire year, due to the
    rocks that have fallen from the structure's support. The bathymetric
    profiles of December and February (winter) show greater erosion from 15
    to 20 m seaward than in the other months. The December profiles A, B
    and C show sediment accumulation near the breakwater. These processes
    of erosion in the deeper depths and sediment accumulation at the base
    of the breakwater cause the storm waves that are produced in this
    season to maintain their energy when approaching the breakwater, and
    upon reaching this zone, the sediment bed serves as a ramp for them to
    slip over the armor stone and flood the harbor. In comparing the
    profiles of 1984 and 1987 with those from this study (1990), an
    increase in depth is observed from the base of breakwater to
    approximately 200 m seaward, allowing the waves to reach the breakwater
    with more strength, than if that decrease in depth were more gradual.
    This increase in depth extends from the beginning up to half of the
    breakwater.

 AB A substance from Taenia solium metacestodes that decreases lymphocyte
    proliferation induced by concanavalin A was isolated. The molecular
    weight of this substance was estimated to be slightly more than 1,450
    Da. Crude metacestode factor was fractionated through a Bio-gel P-6
    column. Peak 1 showed suppressive activity. After incubation with RNase
    the substance lost its activity. Incubation of this material with
    trypsin or papain increased its suppressive activity. It was stable at
    boiling temperature for 10 min. The incubation of this substance with
    murine macrophages had no effect on [H-3]-thymidine uptake by
    cocultured fresh splenic lymphocytes stimulated with concanavalin A.
    Conversely, cocultures of lymphocytes pretreated with the substance and
    fresh splenic lymphocytes showed a decreased incorporation of
    [H-3]-thymidine. These results suggest that this substance is a
    RNA-peptide molecule whose RNA moiety accounts for its suppressive
    activity. The findings also suggest that in vivo the factor may be a
    modulator of the immune response.

    EVOLUTION; ORIGIN; SERIES; SECTION; PLATE
 AB The Guerrero suspect terrane, composed of Late Jurassic-Early
    Cretaceous sequences, extends from Baja California to Acapulco and is
    considered to be coeval with the late Mesozoic igneous and sedimentary
    arc sequences of the Greater Antilles, the West Indies, Venezuela and
    the Western Cordillera of Colombia. These sequences represent the
    remnants of an arc which accreted to the North American and northern
    South American cratons at the end of the Cretaceous.
    In western Mexico, the arc sequences built on continental crust consist
    of high-K calc-alkaline basalts, andesites and rhyolites enriched in
    LREE with abundant siliceous pyroclastic rocks interbedded either with
    Aptian-Albian reefal limestones or red beds. They do not show magmatic
    changes during the arc development. In contrast, the arc sequences
    built on oceanic crust show an evolution with time. Arc activity began
    with the development of depleted low K-tholeiitic mafic suite
    (Guanajuato igneous sequence), followed first by mature tholeiitic
    basalts and then by calc-alkaline olivine basalts interbedded with
    micritic limestones and radiolarian oozes of Early Cretaceous age. At
    the end of the arc growth, during Aptian-Albian times, calc-alkaline
    pillow basalts and andesites poured out in the volcanic front while
    shoshonitic olivine basalts extruded in the back arc. The tholeiitic
    and shoshonitic mafic rocks as well as the calc-alkaline lavas are
    mildly enriched in LREE, Y and Nb and show high epsilon(Nd) ratios,
    typical of oceanic arcs. In contrast, the calc-alkaline mafic suite
    enriched in LREE, Y and Nb exhibits lower epsilon(Nd) ratios suggesting
    that it was derived by the partial melting of a mantle source
    contaminated either by Paleozoic subducted sediments or old source
    enrichments (OIB).

 AB An antigenic extract from Taenia solium metacestodes was evaluated for
    immunogenicity in pig populations from a large area of endemic porcine
    cysticercosis in the State of Guerrero, Mexico. A total of 3,295 pigs
    from 18 villages were immunized with a single dose of 250 mug of
    protein administered intramuscularly. Systematic immunization was also
    performed on pigs (1,076 immunizations) from two of the villages with
    the highest percentages of cysticercosis. A year after immunization,
    porcine cysticercosis decreased from 4.8% and 5.4% to 0%. Immunity
    against the T. solium metacestode was estimated in vitro by
    measurements of H-3-thymidine uptake and inhibition of leukocyte
    migration. Peripheral blood lymphocytes from immunized cysticercotic
    (pigs that had cysticercosis prior to immunization), cysticercotic
    immunized (pigs that acquired cysticercosis after immunization), and
    normal control pigs incorporated H-3-thymidine better than lymphocytes
    from cysticercotic pigs when stimulated with concanavalin A. A
    significant inhibition in the leukocyte migration inhibition test was
    also found in leukocytes from immunized cysticercotic pigs (P < 0.01).
    Histopathologic studies revealed granuloma formation surrounding the
    metacestodes of the immunized cysticercotic and cysticercotic immunized
    pigs. These metacestodes exhibited several stages of destruction. Large
    numbers of eosinophils were frequently observed in a close association
    with the degeneration and destruction of parasites. Metacestodes in
    control cysticercotic pigs were intact and surrounded by a minor
    inflammatory reaction. Finally, the rate of in vitro evagination of
    scolices was high in metacestodes obtained from cysticercotic pigs and
    low or absent in those from immunized pigs (P < 0.01).

 ID DNA AMPLIFICATION; DIAGNOSIS
 AB It has been suggested that the technical complexities, the expense of
    equipment and consumables, and problems associated with contamination
    make the polymerase chain reaction (PCR) inappropriate for use in
    developing countries. These problems were addressed using a novel
    one-tube nested PCR, small reaction volumes and a 'three room' system
    for the detection of Mycobacterium tuberculosis. The PCR of sputum
    samples dried on small filter paper disks was also investigated. Using
    this strategy 5 smear-positive and 15 smear-negative specimens were
    correctly identified by PCR. This method of sample collection has the
    advantage that samples can be sent by post and stored in a minimum of
    space, and remain viable for PCR for at least 4 years after collection.
    These and future modifications to the PCR protocol will make the assay
    more suitable for use in the tropics.

 ID COST-EFFECTIVENESS
 AB Increasing international commitment to Universal Child Immunization
    (UCI) intensifies pressures on already scarce health resources. The
    costs of the 1989/90 measles epidemic were measured in the State of
    Guerrero, Mexico, from the perspective of the health services and 43
    representative communities. Financial loss was incurred from illness in
    families of 70% of the 1211 measles cases in a study population of 50
    294. Some 30% of these families did not have sufficient cash reserves
    and sold labour, farm animals or other assets. Among those families,
    20% took loans in order to pay the health care costs of their
    children's measles, 19% sold grain stores and 4% indentured their
    future labour.
    Standardizing household expenditure on local labour costs, it was
    possible to quantify out-of-pocket expenditure and loss of work time.
    The average cost of a measles case to the community amounted to the
    local equivalent of 18.8 work days of an unskilled labourer, with 27
    work days per household affected, excluding income foregone due to
    early deaths. Hastings and colleagues calculated the average cost of
    measles to British families in 1985 to be 11.09 UK Pounds, considerably
    less than a day's wage for a British unskilled labourer at that time.
    Applying the costs in the 43 communities to the whole State of
    Guerrero, without placing a cash value on some 4000 children aged under
    five who died from measles, the epidemic cost the community the
    equivalent of 1.6 million work days. The health services spent 10% of
    this value on the epidemic. The cost of vaccinating all children in the
    State could be sustained for five years, and increase by 10% per year,
    and it would still be lower than the economic cost of an epidemic to
    the communities.

 AB 1.  Nylon bednets impregnated with different insectides were evaluated
    in 1988 against wild adult mosquito populations, mostly Mansonia
    africana (Theobald) and Anopheles gambiae Giles sensu lato, entering
    experimental verandah-trap huts in The Gambia.  Each bednet had six 10
    x 10 cm holes made in the walls to simulate torn conditions and permit
    female mosquitoes to enter and feed on sleepers.
    2.  Individual net treatments, determined by gas chromatography of net
    samples from before and after 12 weeks use of bednets, were: 
    permethrin 670 +/- 159 and 405 +/- 190 mg/m2 (40% loss), cypermethrin
    37 +/- 8 and 16 +/- 9 mg/m2 (57% loss), deltamethrin 10 +/- 7 and 10
    +/- 8 mg/m2 (no loss), lambda-cyhalothrin 2.6 +/- 0.9 and 1.6 +/- 0.5
    mg/m2 (38% loss), pirimiphos-methyl 4017 +/- 117 and 1160 +/- 319 mg/m2
    (71% loss).
    3.  Washing three times in the traditional manner with local cow-fat
    soap reduced the initial dosages by about 85% of cypermethrin and
    lambda-cyhalothrin, 99.8% of pirimiphos-methyl and left no detectable
    residues of deltamethrin or permethrin.
    4.  The unwashed permethrin-treated bednet reduced the number of
    mosquitoes entering a hut by 60% of An.gambiae s.l. and 68% of Mansonia
    spp.  This deterrency was less pronounced with the other insecticides
    and was lost by washing the bednets.
    5.  Each insecticide, especially lambda-cyhalothrin and
    pirimiphos-methyl, caused significant mortality rates of mosquitoes
    that entered huts with impregnated bednets, and prevented the majority
    of An. gambiae s.l. and Mansonia females from bloodfeeding.  Washing
    completely removed the efficacy of deltamethrin and permethrin treated
    bednets, whereas nets treated with cypermethrin, lambda-cyhalothrin or
    pirimiphos-methyl remained significantly insecticidal after washing.
    6.  Aerial toxicity from the pirimiphos-methyl treated bednet killed
    80% of An. gambiae s.l. confined overnight in the hut at the end of the
    trial, whereas the pyrethroid-treated bednets gave negligible mortality
    rates of mosquitoes.
    7.  Sleepers using the bednets had no medical symptoms significantly
    associated with any of the treatments.  On the contrary, from 216
    interviews, 4/10 complaints were associated with the use of untreated
    nets (P approximately 0.05), perhaps because sleepers were kept awake
    by mosquitoes and became more aware of any ailments.
    8.  It is concluded that permethrin tends mainly to deter mosquitoes
    from house-entry, enhancing personal protection, whereas the other
    insecticides kill higher proportions of the endophilic mosquitoes,
    which would give better community protection against malaria
    transmission.

 AB Wheat (Triticum aestivum L.) yields often are closely related to spike
    number per unit ground area.  This study was conducted to determine
    whether, for soft white winter wheat in a region with a humid
    continental climate, this relationship is determined primarily by
    changes in total dry weight accumulation (TDW), harvest index (HI), or
    both.  The study involved several field experiments in which seeding
    density varied from 6 to 24 g m-2, sowing dates ranged from 14
    September to 1 November, alternate rows were removed in May and early
    June, row spacing varied from 0.16 to 0.32 m, a growth regulator
    (chloroethyltrimethylammonium chloride) was applied at 9.6 kg a.i.
    ha-1, and 11 genotypes (both gibberellic acid sensitive and
    insensitive) were used.  These treatments were used to create a range
    of final spike numbers.  Grain yields ranged from 180 to 570 g m-2, and
    increased with spike numbers per m2.  Total dry weight, which ranged
    from 720 to 1670 g m-2, also increased with spike numbers per m2, such
    that HI remained unchanged as spike number per unit area increased. 
    Harvest index, however, decreased with spike number per plant, and was
    related to kernel weight but not to kernel number per spike.  Positive
    relationships of grain yield to spike number per unit land area thus
    seem to arise from increased TDW rather than enhanced HI.  Examination
    of the reasons for high dry matter production at high spike numbers
    appears worthwhile for subsequent research.

 DT Review
 AB Technological or man-made disasters are a growth industry.  Widely
    publicized industrial disasters like those in Bhopal and Chernobyl are
    only the tip of the iceberg of human and environmental risk from
    technological development.  Other less well publicized disasters,
    including the contamination of food, water and air, have affected
    millions of people.  The 'slow' technological disasters - like air
    pollution, pesticides, radiation, lead, asbestos and other industrial
    hazards - also compromise human intellectual, behavioural and physical
    development.  Although it can be argued that there are hazards attached
    to virtually every industrial activity and that it is almost impossible
    to remove completely the risk of technological disasters, it is
    possible to reduce this risk by decentralizing or deconcentrating
    knowledge on technological processes.  Global recommendations may
    provide a framework for priority action, but they are obviously not
    applicable everywhere with the same intensity.  A measurement-based
    approach is described that is beginning to have an effect in several
    developing countries.

 DT Article
 AB The Late jurassic-Early Cretaceous allochtonous island-arc of rocks of
    central-southern Mexico were considered up to now as a product of an
    east-dipping subduction along the western margin of the North American
    craton.  New stratigraphic, petrological and geochemical data show that
    the Late Jurassic-Early Cretaceous volcano-plutonic series of
    central-southern Mexico belong to an intra-oceanic island arc.  Its
    base displays a complete tholeiitic suite from ultramafic-mafic
    cumulate rocks up to pillow-basalts, whereas the uppermost submarine
    basaltic and andesitic flows display calc-alkaline affinities.  The
    latter are interbedded with volcaniclastic sediments and redeposited
    limestones that yield reworked Albian-Aptian reef fauna.  This island
    arc was generated by a west-south-west dipping subduction of an oceanic
    basin located between the Pacific Ocean and the North American craton.
