Abstract: Introducción. El registro de casos de leishmaniasis en el departamento de Guaviare evidenció la ausencia de estudios entomológicos dirigidos a identificar las especies de Lutzomyia de esa región del país. Objetivo. Determinar las especies del género Lutzomyia en los cuatro municipios del departamento del Guaviare y se alar por antecedentes vectoriales las especies con posible compromiso en la transmisión de la leishmaniasis. Materiales y métodos. El muestreo se realizó con trampas CDC colgadas entre 1,5 m y 9 m de altura. Además, se recolectaron flebótomos con trampa Shannon y en sitios de reposo. Resultados. Se recolectaron flebótomos pertenecientes a 37 especies; 35 de ellas se registran por primera vez para el departamento del Guaviare y cuatro para el país: L. begonae, L. campbelli, L. sericea y L. nematoducta. Las especies más abundantes fueron L. hirsuta 24,3% (148/610), L. yuilli 15,2% (93/610) y L. davisi 10,3% (63/610), seguidas por L. fartigi, L. carrerai, L. antunesi, L. flaviscutellata y L. olmeca bicolor. Conclusión. Se identificaron siete especies de Lutzomyia como posibles vectores de leishmaniasis. Introduction. Although cases of leishmaniasis have been reported in the province of Guaviare, Colombia, no entomological studies were included to identify the Lutzomyia sand fly vector species in that area. Objective. Lutzomyia species were identified from four townships of Guaviare. Probable vectors were named based on those species involved in transmission in other areas. Materials and methods. Sampling was undertaken with CDC light traps suspended at heights between 1.5 m and 9 m. Additional sand flies were collected with Shannon traps and by aspiration of adult flies from daytime resting sites. Results. Sand flies belonging to 37 different species were collected. 35 of them were recorded for the first time in Guaviare Province. Four species were new records for Colombia: Lutzomyia begonae, L. campbelli, L. sericea and L. nematoducta. The most abundant species were L. hirsuta 24.3% (148/610), L. yuilli 15.2% (93/610), L. davisi 10.3% (63/610), followed by L. fartigi, L. carrerai, L. antunesi, L. flaviscutellata and L. olmeca bicolor. Conclusion. Seven of these species of have been associated previously with endemic or epidemic transmission of leishmaniasis.

Abstract: DNA polymorphism is very useful in paternity analysis. The present paper describes paternity studies done using DNA profiles obtained with the (CAC)5 probe. All of the subjects studied were involved in nonjudicial cases of paternity. Genomic DNA digested with HaeIII was run on agarose gels and hybridized in the gel with the (CAC)5 probe labeled with 32P. The mean number of bands larger than the 4.3 kb per individual was 16.1. The mean proportion of bands shared among unrelated individuals was 0.08 and the mean number of test bands was 7.1. This corresponded to an exclusion probability greater than 0.999999. Paternity was excluded in 34.5% of the cases. The mutation frequency estimated from non-excluded cases was 0.01143 bands per child. In these cases, the paternity was confirmed by a locus-specific analysis of eight independent PCR-based loci. The paternity index was computed in all non-excluded cases. It can be concluded that this method is a powerful and inexpensive alternative to solve paternity doubts.

Abstract: La ense anza universitaria en Espa a está envuelta en un proceso de adaptación al Espacio Europeo de Ense anza Superior (EEES) que está trayendo consigo una serie de cambios muy importantes. Una de las modificaciones más controvertidas es la necesidad de adaptar nuestras ense anzas a unos criterios claros de calidad, más aún cuando se trata de asignaturas virtuales. Una de las piezas clave que permite evaluar y proponer una docencia virtual de calidad en este medio es la guía de estudio. En este artículo se propone un modelo de guía de estudio para asignaturas virtuales que asegure unos criterios específicos de calidad.

Abstract: a trial was carried out in areas of the ubpc "gabriel lamot" of the coffee enterprise yateras, guantánamo province, in 2004, to evaluate the effect of the indirect diffuse light intensity management within the coffee plantation and the application of the entomopathogenic fungus beauveria bassiana on populations of hypothenemus hampei ferr. (coleoptora: scolytidae). the experimental plots were arranged in a split plot design with two factors. ¨factor 1¨ was the management of the indirect diffuse light intensity within the coffee plantation and ¨factor 2¨ consisted of six variants of application of b. bassiana. a significant decrease of the percentage of affectation by h. hampei in the field at levels of 0,6 and 2,1%, respectively, could be achieved with shade management in the coffee plantation in a range between 60-70% and direct applications to the foliage of this bioproduct at a concentration of 109 spores.ml-1 at intervals of 30-40 days after mass flowering.

Abstract: Se realizó un estudio prospectivo descriptivo en el Hospital Docente ginecoobstétrico de Matanzas durante el a o 1993 a los pacientes ingresados con el diagnóstico de embarazo cronológicamente prolongado (más de 42 semanas). De un total de 3 652 nacimientos ocurridos, 150 correspondieron a embarazo de más de 42 semanas, para una incidencia de 4,1. De estos, se escogieron 100 casos, que conformaron la muestra en estudio, recogida en un modelo estadístico habilitado al efecto, el cual permitió la conformación de las tablas estadísticas y comparación con la bibliografía revisada al respecto. Se aplicó al método estadístico de tanto porciento con tablas de doble canal, al X2 donde & un valor >< 0,5 para las percentilas prefijadas. Se trabajó con 2 variables biofísicas, el monitoraje y el perfil biofísico, y se correlacionó con variables como: el tipo de parto, las características físicas del líquido amniótico y el conteo de apgar del recién nacido. Se demuestra la eficacia de estos 2 métodos paraclínicos: el monitoraje y el perfil biofísico, y es este último el de mayor índice de confiabilidad o inocuidad. En cuanto a las variables estudiadas en el caso del tipo de parto predominó el eutócico; en las características del líquido predominó el claro, pero no influenció en la mortalidad perinatal, ni en el conteo de apgar bajo los casos con líquido meconial.

Abstract: El Programa Director de Promoción y Educación para la Salud es una expresión de voluntad política y decisión que se encarga de promover, organizar, orientar procesos educativos tendientes a influir en los conocimientos, aptitudes y prácticas relacionadas con la salud del individuo y la comunidad. Si estas acciones educativas se desarrollan en adolescentes la tarea se hace doblemente hermosa y humana. Se realizó un estudio longitudinal y descriptivo de adolescentes que estudian en el Politécnico "Pedro Téllez" del municipio Pinar del Río con la aplicación de técnicas educativas afectivo-participativas como instrumentos de trabajo para evaluar el nivel de conocimientos de Educación para la Salud y factores de riesgos antes y después de una intervención educativa. El universo estuvo formado por 250 alumnos que estudian en el centro escolar y la muestra el 100% del universo en el período de enero 2006 a noviembre 2007, la investigación se realizó en tres etapas, una donde se aplicó la encuesta en la totalidad de la muestra sobre educación para la salud y factores de riesgos, una segunda etapa de intervención que comprendió la ejecución de técnicas afectivas-participativas, una tercera etapa donde se evaluaron los resultados alcanzados. Los datos fueron llevados a figuras y tablas; se aplicó el método estadístico Chi cuadrado. Obteniéndose que el mayor porciento de estudiantes tenían un bajo nivel de conocimientos y al finalizar la intervención educativa se logró que un mayor porciento de los estudiantes poseían elevado nivel de conocimiento. Quedando así demostrado la eficacia del Programa Educativo.
