Chronic aerobic exercise associated to low-dose L-NAME improves contractility without changing calcium handling in rat cardiomyocytes

Braz. j. med. biol. res; 53 (3), 2020
Nitric oxide (NO) inhibition by high-dose NG-nitro-L-arginine methyl ester (L-NAME) is associated with several detrimental effects on the cardiovascular system. However, low-dose L-NAME increases NO synthesis, which in turn induces physiological cardiovascular benefits, probably by activating a protectiv...

Bradycardic and Antiarrhythmic Effects of the D-Limonene in Rats

Arq. bras. cardiol; 113 (5), 2019
Abstract Background: D-limonene (DL) is a monoterpene and is the major component in the essential oil of citrus fruit. It presents antihyperglycemic and vasodilatation activities. Objectives: This study evaluated the cardiovascular effects and potential antiarrhythmic of DL in rats. Methods: Hemodynam...

Mitigating effect of tanshinone IIA on ventricular remodeling in rats with pressure overload-induced heart failure

Acta cir. bras; 34 (8), 2019
Abstract Purpose To investigate the effect of tanshinone IIA (TIIA) on ventricular remodeling in rats with pressure overload-induced heart failure. Methods Pressure overload-induced heart failure model (abdominal aortic coarctation) was established in 40 rats, which were divided into model and 5, 10 an...

Effect of Lactation on myocardial vulnerability to ischemic insult in rats

Arq. bras. cardiol; 108 (5), 2017
Abstract Background: Cardiovascular diseases are the leading cause of mortality and long-term disability worldwide. Various studies have suggested a protective effect of lactation in reducing the risk of cardiovascular diseases. Objective: This study was designed to assess the effects of pregnancy and ...

Effect of Fetal Hypothyroidism on Cardiac Myosin Heavy Chain Expression in Male Rats

Arq. bras. cardiol; 107 (2), 2016
Abstract Background: Thyroid hormone deficiency during fetal life could affect the cardiac function in later life. The mechanism underlying this action in fetal hypothyroidism (FH) in rats has not been elucidated thus far. Objective: The aim of this study is to evaluation the effect of FH on cardiac ...
