Copper induces damage, oxidative stress and cell death in endothelium of chronic intoxicated Wistar rats

Int. j. morphol; 40 (1), 2022
SUMMARY: Reactive Oxygen Species (ROS) are part of the functional balance of various systems, they can generate cellular damage by oxidative stress associated with disease processes such as atherosclerosis, cardiovascular disease, diabetes, and aging. Some studies report that copper induces damage to the...

Exercício Físico Melhora as Funções das Células Progenitoras Endoteliais em Pacientes com Síndrome Metabólica

Arq. bras. cardiol; 117 (1), 2021
Resumo Fundamento As células progenitoras endoteliais (CPEs) desempenham um papel importante na manutenção da função endotelial. A síndrome metabólica (SM) está associada à disfunção das CPEs. Embora o exercício físico tenha um impacto benéfico na atividade das CPEs, seu mecanismo ainda n...

Underexpression of endothelial nitric oxide synthase leads to more severe pulmonary complex vascular lesions associated with HIV patients

Arch. cardiol. Méx; 90 (1), 2020
Abstract Background: Despite increase in survival of human immunodeficiency virus (HIV) patients due to highly active antiretroviral therapy, non-infectious complications are still prevalent such as presentation of lung vasculopathy, even in asymptomatic patients. Endothelial nitric oxide synthase (eNOS...

Effect of miR-134 against myocardial hypoxia/reoxygenation injury by directly targeting NOS3 and regulating PI3K/Akt pathway

Acta cir. bras; 34 (8), 2019
Abstract Purpose To reveal the function of miR-134 in myocardial ischemia. Methods Real-time PCR and western blotting were performed to measure the expression of miR-134, nitric oxide synthase 3 (NOS3) and apoptotic-associated proteins. Lactic dehydrogenase (LDH) assay, cell counting kit-8 (CCK-8), Hoe...

Alprostadil attenuates myocardial ischemia/reperfusion injury by promoting antioxidant activity and eNOS activation in rats

Acta cir. bras; 33 (12), 2018
Abstract Purpose: To investigate the effect of alprostadil on myocardial ischemia/reperfusion (I/R) in rats. Methods: Rats were subjected to myocardial ischemia for 30 min followed by 24h reperfusion. Alprostadil (4 or 8 μg/kg) was intravenously administered at the time of reperfusion and myocar...

Aerobic Swim Training Restores Aortic Endothelial Function by Decreasing Superoxide Levels in Spontaneously Hypertensive Rats

Clinics; 72 (5), 2017
OBJECTIVE: We aimed to determine whether aerobic training decreases superoxide levels, increases nitric oxide levels, and improves endothelium-dependent vasodilation in the aortas of spontaneously hypertensive rats. METHODS: Spontaneously hypertensive rats (SHR) and Wistar Kyoto rats (WKY) were distribu...

Propofol attenuates cytokine-mediated upregulation of expression of inducible nitric oxide synthase and apoptosis during regeneration post-partial hepatectomy

Acta cir. bras; 32 (5), 2017
Abstract Purpose: To determine the effects of propofol and ketamine anesthesia on liver regeneration in rats after partial hepatectomy (PHT). Methods: Male Wistar albino rats were assigned randomly to four groups of 10. Anesthesia was induced and maintained with propofol in groups 1 and 2, and with ket...

A Single Resistance Exercise Session Improves Aortic Endothelial Function in Hypertensive Rats

Arq. bras. cardiol; 108 (3), 2017
Abstract Background: Physical exercise is an important tool for the improvement of endothelial function. Objective: To assess the effects of acute dynamic resistance exercise on the endothelial function of spontaneously hypertensive rats (SHR). Methods: Ten minutes after exercise, the aorta was remove...

Is Local Nitric Oxide Availability Responsible for Myocardial Salvage after Remote Preconditioning?

Arq. bras. cardiol; 107 (2), 2016
Abstract Background: Remote ischemic preconditioning (RIPC) represents an attractive therapy for myocardial protection, particularly when ischemic events can be anticipated. Although several hypothetic mechanisms have been proposed, no definite molecular pathways have been elucidated. Objective: We eva...
