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...

In vitro and in vivo antioxidant potentials of the methanolic crude extract from Inula glomerata Oliv. & Hiern (Asteraceae) and Salacia kraussii (Harv) Harv (Celastraceae)

Reactive oxygen species are implicated in multiple pathological conditions including erectile dysfunction. This study evaluated the in vitro and in vivo antioxidant potential of the methanolic extracts of Inula glomerata and Salacia kraussii. The plant materials were pulverized and extracted with methan...

Rol de la fracción espirada de oxido nítrico en el niño con diagnóstico de asma bronquial

El asma es la enfermedad respiratoria crónica pediátrica más frecuente. En la mayoría de los niños se caracteriza por inflamación de la vía aérea de tipo eosinofílica alérgica. La fracción espirada de óxido nítrico (FENO) es un biomarcador de inflamación eosinofílica de vía aérea, su me...

Effects of vitamin D-induced supernatant of placental explants from preeclamptic women on oxidative stress and nitric oxide bioavailability in human umbilical vein endothelial cells

Braz. j. med. biol. res; 54 (8), 2021
The study evaluated the effect of the supernatant of placental explants from preeclamptic (PE) and normotensive (NT) pregnant women after tissue treatment with or without vitamin D (VD) on oxidative stress and nitric oxide (NO) bioavailability in human umbilical vein endothelial cells (HUVEC). Placental ...

Effects of music therapy on pain and oxidative stress in oocyte pick-up: A randomized clinical trial

Rev. bras. anestesiol; 70 (5), 2020
Abstract Background and objective: The aim was to investigate the effects of Turkish classical music on pain and oxidative stress in patients undergoing oocyte pick-up. Methods: The study was a randomized, controlled trial. The groups included Group NM (Non-Music), control group; Group PM, which compri...

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...

Induction of selective liver hypothermia prevents significant ischemia/reperfusion injury in Wistar rats after 24 hours

Acta cir. bras; 35 (2), 2020
Purpose To investigate the effects of induction of selective liver hypothermia in a rodent model. Methods Seven male Wistar rats were subjected to 90 minutes of partial 70% liver ischemia and topic liver 26°C hypothermia (H group). Other seven male Wistar rats were subjected to 90 minutes of partial 70...

Functional iron deficiency in patients on hemodialysis: prevalence, nutritional assessment, and biomarkers of oxidative stress and inflammation

J. bras. nefrol; 41 (4), 2019
Abstract Introduction: Anemic patients with chronic kidney disease (CKD) can be divided into anemic patients without or with functional iron deficiency (FID). The increase in the number of cases of hemosiderosis in patients on hemodialysis (HD) attributed to excessive intravenous iron replacement has ca...

Inter-Individual Responses to Citrulline Malate Oral Supplementation on Post-Exercise Hypotension in Hypertensives: A 24-Hour Analysis

Arq. bras. cardiol; 113 (2), 2019
Abstract Background: Studies have persuasively demonstrated that citrulline has a key role in the arginine-nitric oxide system, increasing nitric oxide bioavailability, an important mediator of peripheral vasodilation. Objective: To analyze the inter-individual post-exercise hypotension responsivenes...
