A critical approach to reading comprehension in english: teaching intervention with group of teenagers at a non-formal education institution [recurso electr?nico]

The following paper is an action research made with a group of 6 teenagers aged 11-13 from the city of Cali. The project was carried out at a non-formal education institution and basically describes the process of a teaching intervention in which the concepts of Critical Pedagogy and Task-Based Learning were the protagonists. The results show first, that students really need to feel motivated in order to accept a critical approach; second, that the role of the teacher in the achievement of the objectives is extremely relevant; it is necessary for them to have a critical perspective before working on this field besides the constant seeking of information in order to innovate in their classes; third, that the TBL (Task Based Learning) and the critical pedagogy are processes that need some time in order to bear fruits; and fourth, that a needs analysis is essential for the quality of the intervention.

Multi-Etiological Nature of Tuberculosis-Like Lesions in Condemned Pigs at the Slaughterhouse.

Tuberculosis-like lesions (TBL) in pigs have been associated with microorganisms other than mycobacteria. In this work a histopathological and microbiological evaluation of TBL in pigs is shown. A total of 352 samples belonging to 171 pigs totally condemned at slaughterhouse due to generalized TBL were sampled and selected for analysis. Pyogranulomatous (56.2%) and granulomatous lesions (20.2%) were observed in all analysed organs. Most of the granulomas observed in both lymph nodes and lungs belonged to more advanced stages of development (stages III and IV) whereas in the liver and the spleen most of lesions belonged to intermediate stages (stages II and III). Different microorganisms were simultaneously detected from TBL in the 42.7% of the animals. Mycobacterium tuberculosis complex (MTC) (38%), coryneform bacteria (40.3%) and streptococci (28.1%) were the main groups of microorganisms detected after bacteriological analysis, with Trueperella pyogenes and Streptococcus suis as the most frequently isolated species. Mycobacteria belonging to MTC were the most frequently detected pathogens in granulomatous and pyogranulomatous lesions in submandibular lymph nodes (32.7%) and coryneform bacteria were the microorganisms more frequently isolated from lungs (25.9%) and spleen samples (37.2%). These results may provide new insights into the pathogenesis and diagnosis of this pathology. The importance of coryneform bacteria and streptococci in such processes must be evaluated in future studies.

El aprendizaje a través del juego como herramienta en el diseño de actividades de valor añadido en un currículum integrador de Ciencias Biomédicas

Esta actividad, diseñada desde el Departamento de Ciencias Biomédicas Básicas, se apoya en: 1. la integración de materias básicas (para contextualizar la experiencia clínica desde la perspectiva de sus fundamentos); 2. la formación interprofesional al trabajar con alumnos de diferentes Grados de nuestra Facultad y 3. el aprendizaje a través del juego, para facilitar un abordaje motivante y divertido a los destinatarios de la acción. Esta nueva experiencia consiste en una gymkhana por equipos en base a un caso clínico, en la que por primera vez se trabajan el aprendizaje y la docencia en diversas disciplinas básicas integradas, a través del juego y la competición entre grupos de alumnos (TBL).
