BACKGROUND: Ischemia-reperfusion (IR) induces increased release of extracellular vesicles in the heart and exacerbates myocardial IR injury. We have previously shown that propofol attenuates hypoxia/reoxygenation (HR)-induced injury in human umbilical vein endothelial cells (HUVECs) and that microvesicle...
Abstract An acute respiratory syndrome caused by SARS-CoV2 was declared a pandemic by the World Health Organization. Current data in the world and in Brazil show that approximately 40% of patients who died have some type of cardiac comorbidity. There are also robust reports showing an increase in IL-6 / ...
Resumo Fundamento O remodelamento cardÃaco patológico se caracteriza por disfunção diastólica e sistólica, levando à insuficiência cardÃaca. Neste contexto, o cenário disfuncional do trânsito de cálcio miocárdico (Ca2+) tem sido pouco estudado. Um modelo experimental de estenose aórtica t...
BACKGROUND: Testosterone regulates nutrient and energy balance to maintain protein synthesis and metabolism in cardiomyocytes, but supraphysiological concentrations induce cardiac hypertrophy. Previously, we determined that testosterone increased glucose uptake—via AMP-activated protein kinase (AMPK)â€...
Hypoxia-induced apoptosis and inflammation play an important role in cardiovascular diseases including myocardial infarction (MI). miR-369 has been suggested to be a key regulator of cardiac fibrosis. However, the role of miR-369 in regulating hypoxia-induced heart injury remains unknown. Our data indica...
