Ouabain, an endogenous digitalis compound, has been detected in nanomolar concentrations in the plasma of several mammals and is associated with the development of hypertension. In addition, plasma ouabain is increased in several hypertension models, and the acute or chronic administration of ouabain increases blood pressure in rodents. These results suggest a possible association between ouabain and the genesis or development and maintenance of arterial hypertension. One explanation for this association is that ouabain binds to the α-subunit of the Na+ pump, inhibiting its activity. Inhibition of this pump increases intracellular Na+, which reduces the activity of the sarcolemmal Na+/Ca2+ exchanger and thereby reduces Ca2+ extrusion. Consequently, intracellular Ca2+ increases and is taken up by the sarcoplasmic reticulum, which, upon activation, releases more calcium and increases the vascular smooth muscle tone. In fact, acute treatment with ouabain enhances the vascular reactivity to vasopressor agents, increases the release of norepinephrine from the perivascular adrenergic nerve endings and promotes increases in the activity of endothelial angiotensin-converting enzyme and the local synthesis of angiotensin II in the tail vascular bed. Additionally, the hypertension induced by ouabain has been associated with central mechanisms that increase sympathetic tone, subsequent to the activation of the cerebral renin-angiotensin system. Thus, the association with peripheral mechanisms and central mechanisms, mainly involving the renin-angiotensin system, may contribute to the acute effects of ouabain-induced elevation of arterial blood pressure.

São apresentadas algumas aplicações de um sistema "Home-Made" para Extração com Fluido Supercrítico (EFS) na análise de resíduos de pesticidas e de óleos essenciais em alimentos. Foram desenvolvidos diversos estudos com os parâmetros: temperatura, pressão, escolha e concentração de modificadores. Os resultados são apresentados para amostras de maracujá (resíduos de pesticidas organofosforados e piretróides), mel (resíduos de pesticidas organoclorados) e laranja (óleo essencial).

A (mainly votive) missal consisting of seven distinct parts. Put together in several stages, somewhat haphazardly. Parts II and III are probably the oldest parts. The final stage in the composition of the book is probably the addition of part VII. Part II belongs in the same liturgical tradition as C.ö.IV.7 (Oripään Missale I), probably that of Diocese of Linköping. Part III, a votive missal, is an informal copy of a book that would most probably have been used close to a Swedish cathedral (Linköping?). How the present book found its way to Oripää chapel is not known.

A Insuficiência Cardíaca Congestiva (ICC) é uma patologia com incidência crescente e que representa uma condição de grande impacto na saúde pública, com alta morbidade e mortalidade. O excesso de volume é uma complicação prevalente, presente em 80% dos pacientes atendidos com o diagnóstico de ICC. Estratégias farmacológicas e não farmacológicas no manejo terapêutico da ICC visam ao melhor manejo do volume e à redução no uso de diuréticos. A ultrafiltração extracorpórea tem evidenciado melhor controle de peso, redução nos dias de hospitalização e re-hospitalização dos pacientes com ICC. Neste artigo, relatamos dois casos atendidos no Hospital de Clínicas de Porto Alegre, relativos a pacientes com diagnóstico de ICC tratados com diálise peritoneal.
