MERCADO DE TRABAJO E INSERCIÓN PROFESIONAL: EL CASO DE LOS LICENCIADOS EN ACTUARÍA EN MÉXICO Y EN EL ESTADO DE MÉXICO 2005-2013

Esta investigación tiene como objetivo presentar un enfoque que caracterice la situación laboral de los profesionistas, tanto a nivel nacional, como estatal, que dé la pauta para entender las relaciones que se presentan entre los sectores educativo, productivo y social, descubriendo al mismo tiempo las posibilidades y condiciones de empleo de estos profesionistas y haciendo énfasis en el mercado laboral de los egresados de la licenciatura en Actuaría en el Estado de México durante el periodo 2005-2013. Hipótesis: La licenciatura en Actuaría tiene una buena presencia en el mercado laboral, debido a que cuenta con una oferta de trabajo diversificada, es una buena opción ya que dicho mercado no es muy saturado y la remuneración económica es superior al 6 ingreso promedio del total de los profesionistas ocupados, satisfaciendo sus necesidades y cada vez va tomando mayor importancia y popularidad en México, a pesar de que el número de escuelas que ofrecen la licenciatura en Actuaría es reducido, y la información es aún escasa

Improved Detection of Enterotoxigenic Escherichia coli among Patients with Travelers' Diarrhea, by Use of the Polymerase Chain Reaction Technique

This study sought to determine whether a specific polymerase chain reaction (PCR) for enterotoxigenic Escherichia coli (ETEC) toxins after chaotropic extraction of DNA from stool would increase the detection of ETEC over that of conventional oligonucleotide probe hybridization of 5 E. coli colonies per stool sample (a standard method). By DNA hybridization, 29 (21%) of 140 patients were positive for ETEC, and 59 (42%) of 140 were positive for ETEC when PCR was used. Sensitivity of the PCR assay was confirmed through spiked stool experiments to be ∼100-1000 ETEC colonies per sample. Specificity of the assay was determined by showing an absence of ETEC by the PCR technique in a subgroup of 48 subjects and by confirming the presence of ETEC DNA of positive samples by dot blot procedure. PCR technique detected significantly more ETEC infections in these subjects than did the hybridization method (P < .0001

Ganadería Sustentable. Perspectivas regionales de ganadería sustentable para una visión nacional

El documento que aquí se presenta es un resumen de los temas, experiencias y recomendaciones que, desde diferentes perspectivas, intereses y saberes, aportaron los participantes en el 3er Foro de Ganadería Sustentable. Estamos seguros que el lector encontrará en este “gran menú de ideas” algunas que cubran sus intereses particulares; pero será en el seguimiento de los acuerdos y en la puesta en marcha de las propuestas de colaboración y mejora, que la práctica de la ganadería sustentable podrá consolidarse.GI

Detection of ‘long-haired’ Saprolegnia (S. parasitica) isolates using monoclonal antibodies

P. 726-733The ability of five monoclonal antibodies (Mabs) raised against a pathogenic Saprolegnia parasitica isolate from brown trout to detect and differentiate between isolates with bundles of long hairs (S. parasitica) and other Saprolegnia species was determined by means of an indirect immunofluorescence assay. Four of the Mabs used recognized some of the long-haired S. parasitica isolates but also cross-reacted with other Saprolegnia species without bundles of hairs and with Achlya sp. The other Mab (named 18A6) was able to differentiate between the asexual and most of the sexual isolates in the group of long-haired S. parasitica isolates, but did not recognize Achlya sp. or the Saprolegnia species without bundles of hairs, with the exception of S. hypogyna. These results indicate that isolates with bundles of long hairs are closely related with other members of genus Saprolegnia and share several antigens. However, Mab 18A6 seems to recognize an epitope that is expressed mainly in the asexual isolates in the long-haired S. parasitica isolates.S

Al editar este texto e incorporarlo a la bibliografía de los temas de referencia, se enriquecen opciones de consulta para los estudiosos de esos temas en general; pero también para interesados en aspectos tan específicos como la cadena de suministro del mercado hortofrutícola en Texcoco

Sea Ice Microbiota in the Antarctic Peninsula Modulates Cloud-Relevant Sea Spray Aerosol Production

Este artículo contiene 21 páginas, 8 figuras.Sea spray aerosol (SSA) formation plays a major role in the climate system. The Antarctic Peninsula (AP) is affected by the greatest warming occurring in the Southern Ocean; changes in cryospheric and biological processes are being observed. Whilst there is some evidence that organic material produced by ice algae and/or phytoplankton in the high Arctic contributes to SSA, less is known about Antarctic Sea ice (sympagic) regions. To gain insight into the influence of Antarctic Sea ice biology and biogeochemistry on atmospheric aerosol, we report simultaneous water-air measurements made by means of in situ aerosol chamber experiments. For the first time, we present a methodology showing that the controlled plunging jet aerosol chamber settings do not cause major cell disruption on the studied sea ice ecosystems. Larger sea ice phytoplankton cells (>20 μm; mainly diatoms) tend to sediment at the bottomof the chamber (during the 24h experiment) and likely have a minor role on SSA production. When comparing four chamber experiments - we find that the two producing more SSA are the ones with highest abundance of nanophytoplankton cells (<20 μm; mainly nanoflagellates) as well as viruses. Our marine biogeochemical data show two broad groups of dissolved organic carbon: one rich in carbohydrates and proteic material and one rich in humic-like substances; the latter enhancing SSA production. This work provides unique insights into sea ice productivity that modulates SSA production, with potentially significant climate impacts. Further studies of these types are advised in order to see how microbiology impacts the biogeochemical cycling of elements and how aerosols are formed and processed in cold regions.The study was further supported by the Spanish Ministry of Economy through project PI-ICE (no.

Haplotype analysis of the internationally distributed BRCA1 c.3331_3334delCAAG founder mutation reveals a common ancestral origin in Iberia

Background: TheBRCA1c.3331_3334delCAAG founder mutation has been reported in hereditary breast and ovarian cancer families from multiple Hispanic groups. We aimed to evaluateBRCA1c.3331_3334delCAAG haplotype diversity in cases of European, African, and Latin American ancestry. Methods: BC mutation carrier cases from Colombia (n = 32), Spain (n = 13), Portugal (n = 2), Chile (n = 10), Africa (n = 1), and Brazil (n = 2) were genotyped with the genome-wide single nucleotide polymorphism (SNP) arrays to evaluate haplotype diversity aroundBRCA1c.3331_3334delCAAG. Additional Portuguese (n = 13) and Brazilian (n = 18) BC mutation carriers were genotyped for 15 informative SNPs surroundingBRCA1. Data were phased using SHAPEIT2, and identical by descent regions were determined using BEAGLE and GERMLINE. DMLE+ was used to date the mutation in Colombia and Iberia. Results: The haplotype reconstruction revealed a shared 264.4-kb region among carriers from all six countries. The estimated mutation age was similar to 100 generations in Iberia and that it was introduced to South America early during the European colonization period. Conclusions: Our results suggest that this mutation originated in Iberia and later introduced to Colombia and South America at the time of Spanish colonization during the early 1500s. We also found that the Colombian mutation carriers had higher European ancestry, at the BRCA1 gene harboring chromosome 17, than controls, which further supported the European origin of the mutation. Understanding founder mutations in diverse populations has implications in implementing cost-effective, ancestry-informed screening
