BACKGROUND Urocortin is a novel cardioprotective agent that can protect cardiac myocytes from the damaging effects of ischemia/reperfusion both in culture and in the intact heart and is effective when given at reperfusion. METHODS AND RESULTS We have analyzed global changes in gene expression in cardiac myocytes after urocortin treatment using gene chip… (More)
BACKGROUND Apoptosis contributes to cell loss after ischemia/reperfusion injury in the heart. This study describes the time course and level of apoptosis in different cell types in the intact heart during ischemia/reperfusion injury. METHODS AND RESULTS Isolated Langendorff-perfused rat hearts were subjected to perfusion alone (control) or to 35 minutes… (More)
BACKGROUND Platelet-activating effects have been reported with high-dose heparin in acute thrombotic disorders. Recent studies have shown that increased platelet aggregation is due to reduced nitric oxide (NO) production in endothelial cells cultured in the presence of high-dose heparin. The aim of this study was to determine whether heparin can affect the… (More)
Evidence from certain geographical areas links lymphomas of the ocular adnexa marginal zone B-cell lymphomas (OAMZL) with Chlamydophila psittaci (Cp) infection, suggesting that lymphoma development is dependent upon chronic stimulation by persistent infections. Notwithstanding that, the actual immunopathogenetical mechanisms have not yet been elucidated. As… (More)
OBJECTIVES During cardiac failure several ontogenically developed adaptional mechanisms are activated. Among these, heat-shock proteins (HSP) are expressed in response to stress. The aim of the present study was to investigate the HSP72 protein expression in lungs, liver, cardiac and skeletal muscles during congestive heart failure (CHF). METHODS CHF was… (More)
BACKGROUND Ocular adnexal marginal zone B-cell lymphoma (OAMZL) has been associated with Chlamydophila psittaci, an infection that may be transmitted by carrier animals. However, it is still unclear whether exposure to animals affects the risk of OAMZL in comparison with other lymphoma histotypes. We therefore investigated the role of professional and/or… (More)
PROBLEM Early diagnosis of infections with human immunodeficiency virus (HIV) is needed - especially among key populations such as sex workers, transgender people, men who have sex with men and people who use drugs. APPROACH The Brazilian Ministry of Health developed a strategy called Viva Melhor Sabendo ("live better knowing") to increase HIV testing… (More)
Everyday postures in idiopathic scoliosis: is there any correlation with curve morphology?
