Analisa-se a relação entre a cultura trabalho-família existente numa empresa de serviços financeiros e o compromisso organizacional dos empregados, controlando-se variáveis sociodemográficas. A 219 trabalhadores técnicos e profissionais entre 19 e 64 anos, pertencentes a 16 sucursais localizadas na região do Maule (Chile), foram aplicados três instrumentos de medida das variáveis referidas. Observa-se uma relação significativa entre as variáveis constitutivas da dimensão cultura trabalho-família e o compromisso organizacional, estando a cultura fortemente associada a este (r = 0,483, p=0,05). Observou-se que quanto mais apoio diretivo da empresa é percebido por parte dos trabalhadores, maior é o compromisso destes com aquela e, particularmente, seu compromisso dos tipos normativo (r =0,417; p>0,000) e afetivo (r=0,347; p>0,000).

Expresión y efecto del gen de VEGF165 humano en músculo esquelético isquémico de conejos. ¿Necesidad de administración repetitiva para el tratamiento de la enfermedad vascular periféica? / Expression and effects after VEGF165 gene transfer: is it necessary the reiterative administration for the treatment of peripheral vascular disease?

Peripheral vascular disease is a disorder fifficult to treat. Due to the lack of an effective pharmacological therapy, the ischemia of an effective pharmacological therapy, the ischemia of the lower limbs pursues a relentless course, ending many times in the amputation...The authors present in this study a 6 years experience with this management, and recently the effects of an experimental model of peripheral vascular disease in rabbits is evaluated. The results obtained in this study are important because they could attribute to he trnasitority of the genetic expression the contradictory results founded in clinical assays of peripheral vascular disease

Posible rol de la eritropotetina en la reducción del tamaño de infarto de miocardio / Possible role of erythropoietin in the reduction of infarct extension in acute myocardial infarction

Recent experiences demonstrate that erythropoietin (EPO) reduces infarct extension in acute myocardial infarction (AMI) in small rodents, mainly by an anti-apoptotic mechanism, and these facts encourages the possibility that EPO induces the reduction of the necrotic mass after AMI and promotes beneficial remodeling, thus EPO protects myocytes from hypoxia-induced apoptosis
