Abstract Background: High platelet reactivity (HPR) during therapy with acetylsalicylic acid (ASA) is a poor prognostic factor in acute coronary syndromes (ACS). The prevalence of HPR during ACS is greater than that reported in stable diseases. However, it is unclear whether this prevalence of HPR is a ...
Clopidogrel and aspirin are the most commonly used medications worldwide for dual antiplatelet therapy after percutaneous coronary intervention. However, clopidogrel hyporesponsiveness related to gene polymorphisms is a concern. Populations with higher degrees of genetic admixture may have increased prev...
Background: The decline of estrogen levels increases cardiovascular risk in women. Platelets express estrogen receptors and 17β-estradiol- (E2) can produce a protective effect on thrombus formation. The hydroxylation of cholesterol generates several sterols and 27-hydroxycholesterol (27HC) predomina...
Os mecanismos envolvidos na ativaçäo e agregaçäo plaquetária em condiçöes fisiológicas e patológicas, têm sido amplamente investigados. O propósito deste estudo foi: 1. Estabelecer alguns métodos para análise da organizaçäo de elementos contráteis e distribuiçäo da integrina 'ALFA' Ýb ...
O efeito do aluminio foi avaliado em plaquetas humanas de individuos clinicamente saudaveis atraves de estudos de agregacao, peroxidacao e fosforilacao de proteinas em residuo de tirosina com os inibidores plaquetarios "in vitro" (Trolox, AAS, NDGA, EDTA E DFO). Os resultados obtidos demonstraram que o a...
