Salud Pública de México , 2003,
Abstract: OBJETIVO: Estimar la prevalencia de parasitosis intestinal en ni os de zonas de alta marginación y su asociación con indicadores demográficos y socioeconómicos de interés. MATERIAL Y MéTODOS: En una muestra de 1478 menores de edad, de entre 1 a 14 a os, provenientes de 32 comunidades de la región fronteriza de Chiapas, México, de marzo a septiembre de 1998, se recolectaron tres muestras de heces fecales, seleccionadas aleatoriamente a partir del grado de marginación (alto y muy alto) del municipio al que pertenecen, y distancia de la unidad de salud más cercana a la comunidad (<1 hora; 1 hora o más). En una de cada cuatro viviendas con ni os menores de 15 a os de edad, seleccionadas aleatoriamente, se obtuvieron tres muestras de heces fecales de éstos. Se efectuaron análisis bivariados con la prueba de ji cuadrada y multivariados con modelos lineales generalizados. RESULTADOS: La prevalencia global de parasitosis fue de 67% (intervalo de confianza IC 95% 64-70%). Sesenta por ciento de los ni os estaban multiparasitados. La prevalencia de Entamoeba histolytica/E dispar fue de 51.2%, de Giardia lamblia, 18.3% y de Ascaris lumbricoides, 14.5%. La mayor prevalencia de E histolytica/E dispar se asoció con la edad y hablar algún idioma indígena; la de Ascaris lumbricoides con el sitio de obtención de agua y la carencia de refrigerador y electricidad. CONCLUSIONES: Es necesario hacer intervenciones locales de salud (calidad del agua, sistemas de desagüe), programas de educación sanitaria (promoción de la lactancia materna y medidas higiénicas) y promoción del habla de idiomas indígenas entre los médicos de la región.
Pinus taeda cDNA Microarray as a Tool for Candidate Gene Identification for Local Red/Far-Red Light Adaptive Response in Pinus sylvestris  [PDF]

American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.43061
Abstract:

Light quality response is a vital environmental cue regulating plant development. Conifers, like angiosperms, respond to the changes in light quality including the level of red (R) and far-red (FR) light, which follows a latitudinal cline. R and FR wavelengths form a significant component of the entire plant life cycle, including the initial developmental stages such as seed germination, cotyledon expansion and hypocotyl elongation. With an aim to identify differentially expressed candidate genes, which would provide a clue regarding genes involved in the local adaptive response in Scots pine (Pinus sylvestris) with reference to red/far-red light; we performed a global expression analysis of Scots pine hypocotyls grown under two light treatments, continuous R (cR) and continuous FR (cFR) light; using Pinus taeda cDNA microarrays on bulked hypocotyl tissues from different individuals, which represented different genotypes. This experiment was performed with the seeds collected from northern part of Sweden (Ylinen, 68?N). Interestingly, gene expression pattern with reference to cryptochrome1, a blue light photoreceptor, was relatively high under cFR as compared to cR light treatment. Additionally, the microarray data analysis also revealed expression of 405 genes which was enhanced under cR light treatment; while the expression of 239 genes was enhanced under the cFR light treatment. Differentially expressed genes were re-annotated using Blast2GO tool. These results indicated that cR light acts as promoting factor whereas cFR antagonises the effect in most of the processes like C/N metabolism, photosynthesis and cell wall metabolism which is in accordance with former findings in Arabidopsis. We propose cryptochrome1 as a strong candidate gene to study the adaptive cline response under R and FR light in Scots pine as it shows a differential expression under the two light conditions.

Abstract: Objetivo. Analizar el uso de servicios de atención prenatal (AP) en la Región Fraylesca de Chiapas, México, e identificar grupos con menor probabilidad de recibir AP. Material y métodos. En 1994 se realizó una encuesta en una muestra aleatoria de 1 100 viviendas en la que se recopiló información sociodemográfica y sobre AP del último embarazo ocurrido en los dos a os previos al estudio (n=297 mujeres de 15 a 49 a os). La identificación de grupos con menor probabilidad de recibir AP adecuada (cinco o más consultas) se realizó mediante un modelo log-lineal. Resultados. Cuarenta y dos por ciento de las mujeres recibió AP inadecuada (0 a 4 consultas). Las mujeres en "mejor situación socioeconómica" fueron las de mayor probabilidad de recibir AP adecuada: RM 2.47 (IC 95% 1.12-5.44), respecto a las mujeres ubicadas en "peor condición socioeconómica". Conclusiones. Es menester aumentar la calidad de la atención de los servicios, apoyar la labor de las parteras y mejorar las condiciones socioeconómicas de la población.

Abstract: Beh?et's disease (BD) is a multifactorial disorder associated with the HLA region. Recently, the ERAP1 gene has been proposed as a susceptibility locus with a recessive model and with epistatic interaction with HLA-B51. ERAP1 trims peptides in the endoplasmic reticulum to optimize their length for MHC-I binding. Polymorphisms in this gene have been related with the susceptibility to other immune-mediated diseases associated to HLA class I. Our aim was, the replication in the Spanish population of the association described in the Turkish population between ERAP1 (rs17482078) and BD. Additionally, in order to improve the understanding of this association we analyzed four additional SNPs (rs27044, rs10050860, rs30187 and rs2287987) associated with other diseases related to HLA class I and the haplotype blocks in this gene region. According to our results, frequencies of the homozygous genotypes for the minor alleles of all the SNPs were increased among patients and the OR values were higher in the subgroup of patients with the HLA-B risk factors, although differences were not statistically significant. Moreover, the presence of the same mutation in both chromosomes increased the OR values from 4.51 to 10.72 in individuals carrying the HLA-B risk factors. Therefore, although they were not statistically significant, our data were consistent with an association between ERAP1 and BD as well as with an epistatic interaction between ERAP1 and HLA-B in the Spanish population.

Estudios Geologicos , 1991, DOI: 10.3989/egeol.91471-2410
Abstract: The Triassic of the NW Iberian Ranges consists of two carbonatic formations equivalent to the Upper Carbonatic Formation of the Muschelkalk Facies and pass laterally into siliciciastic deposits to the NW. Fossillocalities have been found in both formations. Taphonomic and sedimentologic studies allow for the interpretation as autochthonous associations of the infaunal Bivalves of shallow water marine environments with siliciciastic input. Three faunal associations have been distinguished: 1. Costatoria-Lyriomyophoria association, found in the lower carbonatic formation and the equivalent siliciciastic formation; 2. Teruel Fauna association, found in the upper carbonatic formation; 3. Lingula-Pseudocorbula association, found near the top of the upper carbonatic Formation. The Teruel Fauna is well represented in the Iberian Ranges, and always occur in the Royuela Marls and Limestones Formation, and our fossil localities are its most Northwestern record in the Iberian Ranges up to now, thus extending the presence of the endemic Sephardic Faunas during the Ladinian. El Triásico Medio del sector noroccidental de la Cordillera Ibérica está compuesto por dos formaciones carbonáticas, que se corresponden con la unidad carbonática superior del Muschelkalk, y que hacia el NW pasan lateralmente a una formación terrígena. El registro fósil se encuentra en ambos tipos de formaciones. Tanto el estudio tafonómico como sedimentológico, permiten inferir la presencia de elementos acumulados que podrían corresponder a asociaciones autóctonas, compuestas en su mayoría por bivalvos infaunales de medios marinos someros y sometidos a fuerte influencia de terrígenos. Se caracterizan en la zona tres asociaciones faunísticas: 1. Asociación CostatoriaLyriomyophoria, que aparece tanto en la formación carbonática inferior como en la formación terrígena equivalente; 2. Asociación Fauna de Terue! , que aparece en la formación carbonática superior, y 3. Asociación Lingula-Pseudocorbula, que aparece también en la formación carbonática superior, pero en niveles más altos. La Fauna de Terue! es característica de la Formación Dolomías, Margas y Calizas de Royuela , y está bien representada en toda la Cordillera Ibérica. La presencia de la misma en nuestra zona constituye el registro más noroccidental de esta asociación en la misma. Por tanto, significa la penetración más occidental en la península de las faunas endémicas del Dominio Sefardí durante el Ladiniense.
