Moderate-intensity exercise allows enhanced protection against oxidative stress-induced cardiac dysfunction in spontaneously hypertensive rats

Braz. j. med. biol. res; 52 (6), 2019
The progression of myocardial injury secondary to hypertension is a complex process related to a series of physiological and molecular factors including oxidative stress. This study aimed to investigate whether moderate-intensity exercise (MIE) could improve cardiac function and oxidative stress in spont...

Pharmacological modulation of b-adrenoceptors as a new cardioprotective strategy for therapy of myocardial dysfunction induced by ischemia and reperfusion

Acta cir. bras; 34 (5), 2019
Abstract Purpose: To evaluate the cardioprotective response of the pharmacological modulation of β-adrenergic receptors (β-AR) in animal model of cardiac ischemia and reperfusion (CIR), in spontaneously hypertensive (SHR) and normotensive (NWR) rats. Methods: CIR was induced by the occlusion...

Physical Exercise and Regulation of Intracellular Calcium in Cardiomyocytes of Hypertensive Rats

Arq. bras. cardiol; 111 (2), 2018
Abstract Background: Regulation of intracellular calcium (Ca2+) in cardiomyocytes is altered by hypertension; and aerobic exercise brings benefits to hypertensive individuals. Objective: To verify the effects of aerobic exercise training on contractility and intracellular calcium (Ca2+) transients of c...

Exercise Training Attenuates Sympathetic Activity and Improves Morphometry of Splenic Arterioles in Spontaneously Hipertensive Rats

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: Alterations in the structure of resistance vessels contribute to elevated systemic vascular resistance in hypertension and are linked to sympathetic hyperactivity and related lesions in target organs. Objective: To assess the effects of exercise training on hemodynamic and autonomi...

Captopril alleviates hypertension-induced renal damage, inflammation, and NF-κB activation

Braz. j. med. biol. res; 51 (11), 2018
Hypertensive renal damage generally occurs during the middle and late stages of hypertension, which is typically characterized by proteinuria and renal inflammation. Captopril, an angiotensin-converting enzyme (ACE) inhibitor, has been widely used for therapy of arterial hypertension and cardiovascular d...

The Effect of Physical Resistance Training on Baroreflex Sensitivity of Hypertensive Rats

Arq. bras. cardiol; 108 (6), 2017
Abstract Background: Baroreceptors act as regulators of blood pressure (BP); however, its sensitivity is impaired in hypertensive patients. Among the recommendations for BP reduction, exercise training has become an important adjuvant therapy in this population. However, there are many doubts about the ...

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...

90-kDa N-domain angiotensin I-converting enzyme (ACE): possible marker for hypertension in a renal transplant model

J. bras. nefrol; 39 (1), 2017
Abstract Introduction: Hypertension is nearly universal in kidney transplant and several factors are associated with post transplant hypertension, including immunosuppressive medications and genetic predisposition. Objective: The aims were to evaluate the effects of spontaneously hypertensive rats (SHR...

Repair of bone defects using adipose-derived stem cells combined with alpha-tricalcium phosphate and gelatin sponge scaffolds in a rat model

J. appl. oral sci; 25 (1), 2017
Abstract Objectives This study aimed to evaluate the potential of adipose-derived stem cells (ASCs) combined with a modified α-tricalcium phosphate (α-TCP) or gelatin sponge (GS) scaffolds for bone healing in a rat model. Material and Methods Bone defects were surgically created in the femu...

Imunomarcação para TRAP em tecido de reparação óssea de ratos espontaneamente hipertensos (SHR) tratados com Atenolol

Introdução: A hipertensão arterial tem sido um dos maiores problemas de saúde no mundo, com grandes alterações para as doenças cardiovasculares e renais. O tecido ósseo tem função importante no suporte, proteção e locomoção e está sob o controle de fatores sistêmicos como hormônios e fat...
