RESUMEN

INTRODUCCIÓN: Las prácticas formativas son estrategias pedagógicas con las que los estudiantes se acercan a la práctica profesional y desarrollan destrezas y habilidades en fisioterapia. OBJETIVO: Analizar las representaciones sociales del concepto de práctica formativa en estudiantes de fisioterapia en la ciudad de Cali (Colombia). MATERIAL Y MÉTODOS: Estudio cualitativo con diseño descriptivo, transversal y exploratorio. Los datos se recolectaron con la técnica de listado de palabras de asociación libre aplicada a 135 participantes. El análisis se realizó a través del modelo de los dominios culturales. RESULTADOS: El concepto de práctica formativa en fisioterapia se estructuró a través de los lexemas centrales definición, sentimientos positivos, sentimientos negativos. Los elementos más relevantes de la lista fueron felicidad y ansiedad. CONCLUSIONES: Las representaciones sociales más notables en los estudiantes están asociadas con aspectos relacionados con el ser y las de menos interés corresponden a los relacionados con la adquisición de destrezas y habilidades fisioterapéuticas

OBJECTIVE: To analyse the cultural meanings of the concept of formative practice in physical therapy students in the city of Cali, Colombia. MATERIAL AND METHODS: Qualitative study with descriptive design, cross-sectional and exploratory. The data were collected using the free association word list method from 135 participants. The analysis was conducted through the cultural domain model. RESULTS: The concept of formative practice in physiotherapy was structured through the central lexemes definition, positive feelings, negative feelings. The most relevant elements of the list were happiness and anxiety. CONCLUSIONS: The most notable social representations in students are associated with aspects related to the self, and those of less interest correspond to the acquisition of physiotherapy skills and abilities

RESUMEN

La enfermedad de Kawasaki ha sido objeto de interés por epidemiólogos, clínicos e investigadores, desde su primera descripción en 1967. Su causa no se ha podido identificar, aunque las principales hipótesis apuntan a una etiología infecciosa. Desde el punto de vista patogénico, la incapacidad de recuperar un agente infeccioso en forma consistente y las evidencias anatomopatológicas y de laboratorio de una activación de la inmunidad celular y humoral, tienden a situar la enfermedad de Kawasaki en la categoría de una enfermedad autoinmune. Uno de los principales problemas actuales es la demora en el diagnóstico, que se correlaciona con un peor pronóstico en cuanto a las principales secuelas de la enfermedad, entre las que destaca el compromiso de los vasos coronarios. En este trabajo se realiza una revisión de la enfermedad y se muestra la importancia del diagnóstico y tratamiento precoz, así como se señalan apuntes del comportamiento de esta afección en el Hospital Provincial Pediátrico Docente Eliseo Noel Caamaño, de Matanzas, en el período de 2001 al 2010...(AU)

Kawasaki disease has been studied by epidemiologists, clinicians and researchers, since it was described firstly in 1967. Its cause has not been identified, though the main hypothesis point out to an infectious etiology. From the pathogenic point of view, the incapacity of recovering an infectious agent in a consistent way and the anatomopathological and laboratory evidences of a cellular and humoral immunity activation tend to place Kawasaki disease in the category of an autoimmune disease. One of the main current problems is the diagnosis delay, correlated with a worst prognostic of the main consequences of the disease, the compromise of the coronary vases among them. In this work we make a review of the disease and show the importance of the precocious diagnostic and treatment, and also present notes of the behavior of this disease at the Teaching Provincial Pediatric Hospital Eliseo Noel Caamaño, of Matanzas, in the period from 2001 to 2010...(AU)

RESUMEN

Growth is a complex process in fish. This study was designed to test the effect of different levels of recombinant tilapia growth hormone (tiGH) injected intraperitoneally in juvenile hybrid tilapia Oreochromis hornorum. Tilapia GH cDNA was cloned from hybrid O. hornorum tilapia. The mature protein was expressed in E. coli under regulation of the phage T7 promoter. The E. coli-derived tiGH was partially purified to 67% purity and, following renaturation, was shown to be biologically active in in vivo and in vitro assays. Recombinant tiGH stimulated extracellular matrix synthesis as shown by 35S-sulfate uptake in ceratobranchial cartilage explants. Zero, 0.1, 0.5 and 2.5 µg tiGH/g body weight (gbw) were injected in tilapia, and the effects on the growth-promoting action, hepatosomatic index (HSI), and mRNA insulin-like growth factor (IGF) induction were measured. A significant increase in the body weight (P < 0.05) and length (P < 0.01) was observed in tilapia receiving 0.5 µg tiGH/gbw. However, tilapia receiving 0.1 and 2.5 µg tiGH/gbw did not show an increase in body weight and length with respect to the control group receiving BSA injections. Binding sites for the recombinant tiGH were identified in the liver. Consistent with its somatotropic actions, the IGF mRNA induction was observed in the groups injected with 0.1 and 0.5 µg tiGH/gbw (P < 0.05). No significant increase in the HSI was detected in the injected groups when compared to the control group. These results demonstrated that the injection of biologically active E. coli-derived tiGH produces physiological changes in juvenile tilapia that ultimately resulted in a growth-promoting action only at a dose of 0.5 µg tiGH/gbw.
