Passive Cigarette Smoking Impact on Blood Pressure Response to Epinephrine and Felypressin in 1K1C Hypertensive Rats Treated or not with Atenolol

Arq. bras. cardiol; 114 (2), 2020
Abstract Background: Cigarette smoking is usually associated with hypertension and may modify vasoconstrictor response. Objective: The present study aimed to analyze and compare the interaction of passive cigarette smoking and hypertension on epinephrine and felypressin blood pressure effects after int...

Possible mechanisms involved in the effect of the subchronic administration of rosuvastatin on endothelial function in rats with metabolic syndrome

Braz. j. med. biol. res; 53 (2), 2020
Metabolic syndrome is a multifaceted condition associated with a greater risk of various disorders (e.g., diabetes and heart disease). In a rat model of metabolic syndrome, an acute in vitro application of rosuvastatin causes relaxation of aortic rings. Since the outcome of a subchronic rosuvastatin trea...

Effects of in vitro amitriptyline, fluoxetine, tranylcypromine and venlafaxine on saphenous vein grafts

Abstract Objective: In this study, we aimed to examine the effects of amitriptyline, fluoxetine, tranylcypromine and venlafaxine on saphenous vein grafts in coronary artery bypass graft surgeries. Methods: 59 patients (40 males and 19 females; mean age 65.1 years, distribution: 45-84 years) who had cor...

The alterations of microvasculature, tyrosine phosphorylation, and lipid peroxidation in kidney of rats treated with valproic acid

Int. j. morphol; 37 (1), 2019
SUMMARY: Valproic acid (VPA), an antiepileptic drug, has been demonstrated to damage histology and to change tyrosine phosphorylation patterns with increased oxidative stress in perirenal tissues. This study aimed to investigate the effect of VPA on microstructure, tyrosine phosphorylation, and lipid per...

Vasodilatory efficacy and impact of papaverine on endothelium in radial artery predilatation for cabg surgery: in search for optimal concentration

Abstract Objective: The aim of this study was to compare the efficacy of two different papaverine concentrations (0.5 mg/ml and 2 mg/ml) for vasospasm prevention and their impact on endothelium integrity. Methods: We have studied distal segments of radial arteries obtained by no-touch technique from co...

Suppression of wheal and flare in histamine test by the main H1 antihistamines commercialized in Brazil

An. bras. dermatol; 93 (2), 2018
Abstract: Background: Several dermatoses are mediated by histamine, such as urticaria, angioedema, and papular urticaria. There are no Brazilian studies comparing the potency of antihistamines. Objectives: To evaluate the tolerability and efficacy of the main commercial brand and generic H1 antihistami...

Reactividad vascular in vitro y estudio morfométrico de venas safenas utilizadas como bypass coronario: técnica "no-touch" versus convencional

Rev. chil. cir; 70 (5), 2018
Resumen Introducción: Prolongar la permeabilidad de los injertos utilizados en bypass coronario es un desafío constante. Objetivo: Comparar anatomofuncionalmente venas safenas humanas (VSH) extraídas con técnica convencional (TC) vs técnica "no-touch" (NT). Material y Método: Estudio experimenta...

The role of potassium channels in the endothelial dysfunction induced by periodontitis

J. appl. oral sci; 26 (), 2018
Abstract Objective: Periodontitis is associated with endothelial dysfunction, which is clinically characterized by a reduction in endothelium-dependent relaxation. However, we have previously shown that impairment in endothelium-dependent relaxation is transient. Therefore, we evaluated which mediators ...

Effects of a Single Bout of Resistance Exercise in Different Volumes on Endothelium Adaptations in Healthy Animals

Arq. bras. cardiol; 108 (5), 2017
Abstract Background: Resistance exercise (RE) has been recommended for patients with cardiovascular diseases. Recently, a few studies have demonstrated that the intensity of a single bout of RE has an effect on endothelial adaptations to exercise. However, there is no data about the effects of different...

Influence of antihypertensive drugs on aortic and coronary effects of Ang-(1-7) in pressure-overloaded rats

Braz. j. med. biol. res; 50 (4), 2017
This study investigated the influence of antihypertensive drugs, such as angiotensin-converting enzyme inhibitors (ACEIs), AT1 receptor blockers (ARBs), voltage-gated L-type calcium channel blockers, and mineralocorticoid receptor antagonists (MRAs), on the effects of angiotensin-(1-7) [Ang-(1-7)] on aor...
