Effect of Physical Training on Nitric Oxide Levels in Patients with Arterial Hypertension: An Integrative Review

Abstract The regular practice of physical exercise as a non-pharmacological treatment of arterial hypertension (AH) has been encouraged due to causing a series of physiological responses in the cardiovascular system, such as the production of vasoactive substances, including nitric oxide (NO). NO is a re...

Las hormonas femeninas en fisiología renal: Sensibilidad a la sal y regulación de la proliferación epitelial
Female hormones in renal physiology. Salt sensitivity and regulation of epithelial proliferation

Medicina (B.Aires); 80 (2), 2020
Un tercio de la población mundial tiene niveles anormalmente altos de presión arterial, hipertensión, responsable de casi el 50% de las muertes por accidente cerebrovascular y enfermedad coronaria. La sensibilidad a la sal es un factor de riesgo para la morbilidad y mortalidad cardiovascular y tambié...

Influence of Polymorphism of Vitamin D Receptor (Fok I) on Hypertension

Abstract Evidence suggests that polymorphisms in the gene encoding a vitamin D receptor might affect blood pressure. The objective of this systematic review was to investigate the association between hypertension and vitamin D receptor (Fok I) gene polymorphism. A literature search was performed accordin...

Actualización en el manejo clínico de la hipertensión hiporreninémica

Rev. méd. Chile; 147 (4), 2019
The renin-angiotensin-aldosterone system modulates volume, sodium and potassium homeostasis. In the setting of a high sodium diet, up to 30% of patients with hypertension have a low or suppressed renin and increased volume. This phenotype of low renin hypertension (LRH) is multifactorial and includes inf...

Effects of Chronic Exposure to Mercury on Angiotensin-Converting Enzyme Activity and Oxidative Stress in Normotensive and Hypertensive Rats

Arq. bras. cardiol; 112 (4), 2019
Abstract Background: Mercury's deleterious effects are associated with increased cardiovascular risk. Objective: To determine whether chronic exposure to inorganic mercury increases the activity of angiotensin-converting enzyme and its relationship with oxidative stress in several organs and tissues. ...

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...

Rev. méd. Chile; 146 (6), 2018
Background: There is a wide interindividual variability in the response to a period of exercise training. The science have reported that a minimum of participants could be non-responders for improving different health-related outcomes after training. Aim: To compare the effects of a 6-weeks exercise pro...

Endothelial Dysfunction and Inflammation Precedes Elevations in Blood Pressure Induced by a High-Fat Diet

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: Obesity leads to a chronic inflammatory state, endothelial dysfunction and hypertension. Objective: To establish the time-course of events regarding inflammatory markers, endothelial dysfunction, systolic blood pressure (SBP) in obesity in only one experimental model. Methods: We ...
