RESUMO

Fundamento: La educación superior de Ecuador debe responder a las políticas educacionales en cuanto a su labor de formar a los futuros profesionales de la salud integralmente, donde las transformaciones de la ciencia y la tecnología juegan un rol fundamental. Métodos: En el estudio se ofrece una caracterización del comportamiento de la aplicación de las tecnologías de la información en la formación de talento humano en salud en el Instituto Superior Tecnológico Bolivariano de Tecnología. Se efectuó una revisión bibliográfica del tema, análisis documental y observación de las locaciones empleadas, luego se procedió a una triangulación metodológica de la información resultante. Resultados: Los resultados se agrupan según sus características en este centro de altos estudios, posibilidades de empleo, infraestructura existente, y se muestran algunos ejemplos. Conclusiones: A partir de su puesta en marcha se han introducido diferentes proyectos macrocurriculares y desarrollado un proceso de enseñanza aprendizaje orientado y efectivo que propicia la formación de un profesional integral, capaz de desarrollar el pensamiento crítico que aporte al desarrollo sostenible del país(AU)

RESUMO

The aim of this study is to register the presence of aquatic insects during the rainy and dry seasons, in 15 dune lakes of the Gulf of Mexico's coastal zone. These ecosystems lodge a wealth of 62 families, 60 of them present during the rainy season and 46 during the dry period. At both times Coleoptera is the order with a greater number of families, followed by Diptera. The first one is the most diverse, but Chironomidae (Diptera) is the most abundant, representing 40% of the total number of individuals. We used high rank taxa to quantify the biodiversity based on the principle that a high number of families or genus is supposed to include a greater number of species. There were not significant differences in the alpha diversity within the same lake during the two climatic seasons. The trophic structure is dominated by the detritivorous groups (57% of scrapers, collectors, gatherers, shredders), followed by predators (38%) and herbivores (5%). These numbers indicate that dune lakes have a great amount of organic matter. The results obtained contradict our working hypothesis, thus it was rejected, in summary, because there were no important differences in family composition, abundance of individuals and trophic structure of the lakes between the rainy and dry seasons.

RESUMO

El objetivo de este trabajo fue registrar la presencia de insectos acuáticos durante la estación de lluvias y durante las secas en 15 lagos interdunarios localizados en la zona costera del Golfo de México. Estos sistemas albergan una riqueza de 62 familias en general, registrándose en época de lluvias un total de 60 familias y en secas 46. En ambas épocas Coleoptera es el orden con mayor número de familias seguido de Diptera. A pesar que la primera es la más diversa no es la más abundante, ya que la familia Chironomidae (Diptera) engloba un 40 por ciento de la abundancia total de individuos capturados. La utilización de taxa de alto rango para cuantificar la biodiversidad se basa en el principio de que un número elevado de géneros y/o familias se supone que alberga un mayor número de especies. No se encontraron diferencias significativas en la riqueza de familias entre la época de secas y la de lluvias para cada lago. La estructura trófica encontrada está dominada por familias de detritófagos (57 por ciento), seguido de los depredadores (38 por ciento) y el resto son herbívoros. Ello es un indicador de que estos cuerpos de agua presentan gran cantidad de materia orgánica. Con los resultados que se obtuvieron nuestra hipótesis de trabajo se rechazó, ya que no se encontraron diferencias en la riqueza, diversidad y estructura trófica de los lagos entre las épocas de secas y las de lluvias.

RESUMO

The natural habitat of Paracoccidioides brasiliensis remains undefined but the repeated demonstration of infection by this fungus in the nine-banded armadillo Dasypus novemcinctus has opened interesting research avenues. We report here the isolation of this fungus from the spleen of a naked-tailed armadillo Cabassous centralis (Miller 1899) captured in a coffee farm localized in the Colombian endemic area for paracoccidioidomycosis. This particular isolate was identified by its dimorphism and also by comparison of the PbGP43 gene and ribosomal internal transcribed spacer regions (ITS) with recognized P brasiliensis strains. This finding extends the range of naturally acquired infections in mammals of the family Dasypodidae and confirms the existence of this human pathogen in areas where human paracoccidioidomycosis is known to occur.
