Abstract: Comparamos las prevalencias de enteropa-rasitosis a partir de 420 individuos, 306 de ellos eran indígenas y 114 eran mestizos, sin dife-renciación de género, y de todos los rangos de edad, de la Sierra de Nayarit. Se hicieron seis viajes al campo a la región durante un a o para recoger muestras de materia fecal, algunos individuos proporcionaron solamente una muestra y otros cinco muestras. Las muestras de materia fecal fueron diluidas en una solución de formalina al 10% en una relación 1:10, para su conservación durante su transporte a la Ciudad de México, donde se procesaron por análisis coproparasitoscópico directo te ido con solución de lugol. Nosotros encontramos 59,8% de Entamoeba histolytica, 22,2% de Giardia lamblia, 22,2% de Enterobius vermicularis, 15,4% de Hymenolepis nana, 2 casos de taeniosis (0,7%), 21 casos de ascariosis (6,9%), 2 casos de estrongyloidosis (0,7%) y 7 casos de trichuriosis (2,3%) entre la población huichol. En la población mestiza, encontramos 43,9% de entamoebosis, 14,0% de giardiosis 9,6% de hymenolepiosis, 5 casos de ascariosis, 2 de taeniosis, 1 de strongyloidosis y 1 de enterobiosis. Los resultados se analizaron por la prueba del Chi-cuadrada y revelaron diferencias estadísticas significativas entre las dos poblaciones estudiadas We compared the prevalences of enteroparasitoses from 420 individuals, 306 of them were indigenous and 114 were mestizo persons, without gender differentiation, and of all ages from the Nayarit mountain range. Six field trips were made to the region during one year to collect the stool samples, some individuals provided only one sample and other even five. Stool samples were suspended 1:5 with 10% formalin for their transportation to Mexico City, where they were processed by direct parasitoscopic analysis with lugol solution We found Entamoeba histolytica, 59.8%; Giardia lamblia, 22.2%; Enterobius vermicularis, 22.2%; Hymenolepis nana, 15.4%; 2 cases of taeniosis (0.7%), 21 of ascariosis (6.9%), 2 of strongyloidosis (0.7%) and 7 of trichuriosis (2.3%) among the huichol population. For the mestizo population, we found 43.9% of entamoebosis, 14.0% giardiosis, 9.6% hymenolepiosis, 5 cases of ascariosis, 2 of taeniosis, 1 of strongyloidosis and 1 of enterobiosis. Chi-square test revealed statistically significant differences between the two populations for some of the calculated prevalences

Abstract: three different interventions to control triatoma dimidiata in the state of veracruz were implemented: x-1 = whole dwelling spraying, x-2 = middle wall spraying, x-3 = household cleaning. cyfluthrin was sprayed 3 times with 8 month intervals. after each spraying, insects were collected and sent to the laboratory to be recorded and to determine genus and species of the adult triatomine bugs, and nymphs were counted. trypanosoma cruzi presence was determined. with x-1, the infestation, colonization, and natural infection indexes were reduced to 0% in the 3 localities, with respect to t0. with x-2, the infestation index was reduced to 10% at t3 in 3 localities; the colonization index was reduced to 0% in only 1 locality at t3, and the natural infection index was reduced to 0% at t3. with x-3 the 3 indexes were not effectively reduced but they decreased with respect to the baseline study. insecticide application to the whole dwelling is a more efficient intervention than its application to only the lower half of the walls and to the cleaning of houses.

Abstract: Limb-girdle muscular dystrophy type 2A (LGMD2A) is a recessive genetic disorder caused by mutations in calpain 3 (CAPN3). Calpain 3 plays different roles in muscular cells, but little is known about its functions or in vivo substrates. The aim of this study was to identify the genes showing an altered expression in LGMD2A patients and the possible pathways they are implicated in. Ten muscle samples from LGMD2A patients with in which molecular diagnosis was ascertained were investigated using array technology to analyze gene expression profiling as compared to ten normal muscle samples. Upregulated genes were mostly those related to extracellular matrix (different collagens), cell adhesion (fibronectin), muscle development (myosins and melusin) and signal transduction. It is therefore suggested that different proteins located or participating in the costameric region are implicated in processes regulated by calpain 3 during skeletal muscle development. Genes participating in the ubiquitin proteasome degradation pathway were found to be deregulated in LGMD2A patients, suggesting that regulation of this pathway may be under the control of calpain 3 activity. As frizzled-related protein (FRZB) is upregulated in LGMD2A muscle samples, it could be hypothesized that β-catenin regulation is also altered at the Wnt signaling pathway, leading to an incorrect myogenesis. Conversely, expression of most transcription factor genes was downregulated (MYC, FOS and EGR1). Finally, the upregulation of IL-32 and immunoglobulin genes may induce the eosinophil chemoattraction explaining the inflammatory findings observed in presymptomatic stages. The obtained results try to shed some light on identification of novel therapeutic targets for limb-girdle muscular dystrophies.

Abstract: La violencia contra las mujeres o violencia de género está recibiendo una mayor atención social e institucional en nuestro país culminando con la Ley Orgánica 1/2004, de 28 de diciembre, de Medidas de Protección Integral contra la Violencia de Género. La exposición a la violencia de género en el ámbito doméstico se ha demostrado que es también causante de efectos negativos para los hijos e hijas de las mujeres víctimas, cualquiera que sea la edad de los menores, quienes pueden sufrir la violencia de forma directa, en forma de malos tratos físicos o emocionales, o de forma indirecta, siendo testigos de los actos violentos que padecen sus madres. En el presente trabajo se exponen las repercusiones que tiene para el desarrollo evolutivo, emocional, cognitivo y social de los menores, el ser testigos de la violencia hacia sus madres, así como el problema de la transmisión transgeneracional de los comportamientos violentos.

Abstract: Objective: The purpose of this study was to identify the best predictors of dyslipidemias in Mexican obese children using different anthropometric and body composition measurements. Methods: In an observational, cross-sectional study, 905 children from 5 schools were measured for weight, height, waist and hip circumference, and triceps and subscapular skinfolds. A fasting blood sample was taken from a random sub-sample of 306 children to determine lipid profile. Abnormal total cholesterol, LDL, HDL, triglycerides, total cholesterol to HDL ratio, and LDL to HDL ratio, were determined. Logistic regressions and ROC analysis were carried out to determine the best anthropometric predictors of these risk factors. Results: Prevalence of elevated total cholesterol, triglycerides and LDL cholesterol was 14%, 56% and 58%, respectively. In logistic regressions, BMI and triceps skinfold had the highest odds ratios to predict elevated total cholesterol (1.05, 95%CI: 0.97 - 1.14; 1.07, 1.01 - 1.13, respectively), triglycerides (1.19, 1.11 - 1.27; 1.12, 1.08 - 1.17, respectively), LDL cholesterol (1.11, 1.04 - 1.18; 1.09, 1.05 - 1.14, respectively), total cholesterol to HDL ratio (1.06, 1.00-1.14; 1.07,1.03-1.12, respectively) and LDL to HDL ratio risk (1.08,1.01-1.15; 1.07, 1.03-1.12, respectively). After BMI and triceps skinfold, subscapular skinfold also predicted dyslipidemias, except for low HDL; both skinfolds had a narrower odds ratio confidence interval than BMI. In ROC analysis, subscapular skinfold was the best predictor of elevated triglycerides with an AUC ≥ 0.7. Conclusion: Anthropometric measurements are not strongly associated with dyslipidemias in Mexican children. However, since triceps and subscapular skinfolds were better predictors than other anthropometry measures, they may be a simple way to predict dyslipidemias in Mexican children.

Abstract:

Objective: To determine the levels and isotypes of aCl, as well as anti beta 2 glycoprotein 1 (antiβ2-GP1) antibodies in serum and amniotic fluid of pregnant patients with SLE and/or APLS, and healthy pregnant women serving as a control group. Material and Methods: We analyzed serum and amniotic fluid of pregnant patients with SLE and/or APLS, and of healthy pregnant women through ELISA. Results were compared using a Student’s T test. Results: 6 of 13 patients (46.1%), 5 with SLE and one with primary APLS had antiphospholipid antibodies in amniotic fluid. Two patients had IgG aCl and 4 patients had antiβ2-GP1 (one of them also showing IgM) in amniotic fluid. In serum, 4 patients (30%) had antiphospholipid antibodies present (one IgG aCl and three anti β2-GP1) as opposed to none in the control group having antiphospholipid antibodies in amniotic fluid. Only one control had IgM aCl in serum. Antiβ2-GP1 in the amniotic fluid of patients showed a statistically significant value when compared to controls. Conclusion: aCl and antiβ2-GP1 may be present in the amniotic fluid of patients with and without a history of fetal loss. The presence of IgM aCl and antiβ2-GP1 in amniotic fluid suggests its localized production.

Palaeoenvironmental record of the last 70 000 yr in San Felipe Basin, Sonora desert, Mexico: preliminary results

Geofísica internacional , 1999,
Abstract: Preliminary results of a palaeoenvironmental research which includes particle size analyses, diatom and rock-magnetic analyses for a 9.5 m long core from Laguna Seca de San Felipe (LSSF), Baja California, are presented. AMS 14C dating gives an extrapolated age of ca. 70 kyr for the sequence analysed. Rock-magnetic measurements (including χ, χfd%, ARM, SIRM, hysteresis parameters and S ratios), organic content (LOI) and particle size distribution show highly contrasting conditions between glacial and late glacial-Holocene sediments. Dry conditions prevailed between 70 000 and 45 000 yr ago. The full glacial, between 34 000 and 19 000 yr ago, is characterized by moist conditions. The late glacial-Holocene sediments display a five-fold increment in most of the magnetic parameters and in sedimentation rate. This change is interpreted as an increment in runoff waters. At ca. 7000 yr B.P., a dry period is recorded, which probably spans until 6000 yr B.P., when moist conditions return. The onset of the actual arid characteristics occurred around 4000 yr B.P.
