ABSTRACT

Las consecuencias fisiopatológicas y terapéuticas de los pacientes con trauma y con shock hemorrágico grave son causas de la alta mortalidad que muchas veces se escapan de nuestro control. Son la acidosis, la hipotermia y la coagulopatía las complicaciones que irremediablemente llevan a la muerte a los pacientes cuando no son previstas o prevenidas adecuadamente, y nos obligan a postergar el tratamiento quirúrgico definitivo con el objetivo de lograr una mayor supervivencia, mediante pasos consecutivos y ordenados basados en la tolerancia fisiológica del paciente, elemento este que hasta hace alrededor de una década no se tenía en cuenta en la reanimación del paciente con trauma grave. Estas estrategias han sido denominadas "cirugía de control de daños". En este trabajo nos propusimos realizar una revisión de las causas, consecuencias y tratamiento de los componentes de la tríada mortal para un mejor manejo del paciente traumatizado grave...

ABSTRACT

The study of the Schistosoma mansoni genome, one of the etiologic agents of human schistosomiasis, is essential for a better understanding of the biology and development of this parasite. In order to get an overview of all S. mansoni catalogued gene sequences, we performed a clustering analysis of the parasite mRNA sequences available in public databases. This was made using softwares PHRAP and CAP3. The consensus sequences, generated after the alignment of cluster constituent sequences, allowed the identification by database homology searches of the most expressed genes in the worm. We analyzed these genes and looked for a correlation between their high expression and parasite metabolism and biology. We observed that the majority of these genes is related to the maintenance of basic cell functions, encoding genes whose products are related to the cytoskeleton, intracellular transport and energy metabolism. Evidences are presented here that genes for aerobic energy metabolism are expressed in all the developmental stages analyzed. Some of the most expressed genes could not be identified by homology searches and may have some specific functions in the parasite
