1. "Função endotelial em adultos jovens com infarto do miocárdio. Influências ambientais e genéticas" / Endothelium function in young adults with myocardial infarction
A disfunção endotelial atua tanto na aterogênese como na precipitação das síndromes coronárias agudas. A redução da biodisponibilidadedo óxido nítrico é expressão de endotélio disfuncional. O mecanismo desta redução não está elucidado. A presença de disfunção endotelialfoi correlacionada com fatores de risco (FR), nitrato sanguíneo e fa

2. Relaxin is essential for renal vasodilation during pregnancy in conscious rats
Marked vasodilation in the kidney and other nonreproductive organs is one of the earliest maternal adaptations to occur during pregnancy. Despite the recognition of this extraordinary physiology for over four decades, the gestational hormone responsible has remained elusive. Here we demonstrate a key role for relaxin, a member of the IGF family that is secre

3. Molecular and biochemical characterization of dNOS: a Drosophila Ca2+/calmodulin-dependent nitric oxide synthase.
Nitric oxide (NO) is an intercellular messenger involved with various aspects of mammalian physiology ranging from vasodilation and macrophage cytotoxicity to neuronal transmission. NO is synthesized from L-arginine by NO synthase (NOS). Here, we report the cloning of a Drosophila NOS gene, dNOS, located at cytological position 32B. The dNOS cDNA encodes a p

4. Endothelium-dependent contractions and endothelial dysfunction in human hypertension
The endothelium is a crucial regulator of vascular physiology, producing in healthy conditions several substances with a potent antiatherosclerotic properties. Accordingly, the presence of endothelial dysfunction is associated with subclinical atherosclerosis and with an increased future risk of cardiovascular events. A large body of evidence supports the fu

5. Quantification of Intermediates Formed during the Reduction of Nitrite by Deoxyhemoglobin*S⃞
Nitric oxide (NO) plays a crucial role in human physiology by regulating vascular tone and blood flow. The short life-span of NO in blood requires a mechanism to retain NO bioactivity in the circulation. Recent studies have suggested a mechanism involving the reduction of nitrite back to NO by deoxyhemoglobin in RBCs. A role for RBCs in transporting NO m
