Correlación entre actividad física en la vida diaria y biomarcadores de estrés oxidativo y metabólicos en adultos mayores

Med. UIS; 33 (1), 2020
Resumen Introducción: el envejecimiento se caracteriza por cambios fisiológicos, entre ellos un aumento del estrés oxidativo (EO), que es un factor de riesgo para el desarrollo de múltiples patologías. La actividad física en la vida diaria (AFVD) es un factor protector para la salud y podría esta...

Sorting and cryopreservation of goat sperm with or without phenolic compounds

The objectives of this study were to evaluate goat sperm sorting in continuous Percoll® density gradients and gamete freezability, in the presence or absence of phenolic antioxidants. For this, semen pools were sorted, frozen, and evaluated. The non-selected group (NSg) presented lower progressive motil...

Otoprotection Mechanisms Against Oxidative Stress Caused by Cisplatin

Abstract Introduction Cisplatin damages the auditory system and is related to the generation of free radicals. Glutathione peroxidase is an endogenous free radicals remover. Objective To investigate the mechanisms involved in otoprotection by N-acetylcys- teine through the expression of glutathione p...

Efectos biológicos protectores del ejercicio en modelos experimentales de tabaquismo: más allá de la cesación y la abstinencia

El tabaquismo es considerado una de las principales causas de morbilidad y mortalidad en la población general. En Chile la prevalencia de tabaquismo alcanza el 36,7% en hombres y 28,5% en mujeres. En este contexto, diversas estrategias farmacológicas y no farmacológicas han sido propuestas para promov...

Nutritional Status and Indicators of Oxidative Stress among End-Stage Renal Disease Patients Treated with Continuous Ambulatory Peritoneal Dialysis

Prensa méd. argent; 106 (1), 2020
Background: The objective of the study was to determine the oxidative stress (OS) intensity depending on the nutritional status (NS) among end-stage renal disease patients treated with continuous ambulatory peritoneal dialysis (CAPD) and to investigate the effectiveness of medical strategies for the corr...

Quantification of DNA Damage in Different Tissues in Rats with Heart Failure

Arq. bras. cardiol; 114 (2), 2020
Abstract Background: Chronic heart failure (CHF) is a complex syndrome which comprises structural and functional alterations in the heart in maintaining the adequate blood demand to all tissues. Few investigations sought to evaluate oxidative DNA damage in CHF. Objective: To quantify the DNA damage usi...

Vitamin C administration attenuated artemether induced hepatic injury in rats

Int. j. morphol; 38 (1), 2020
This research was designed to investigate the potential protective effect of vitamin C supplementation against hepatocyte ultrastructural alterations induced by artemether (antimalarial drug) administration. Twenty-four adult male albino rats were used in this study and were divided into four groups (n=6...

Suppression of hepatic apoptosis induced by acetaminophen using a combination of resveratrol and quercetin: an association of oxidative stress and interleukin-11

Int. j. morphol; 38 (1), 2020
We sought to determine whether the combined polyphenolic compounds, resveratrol and quercetin can substantially protect against modulation of hepatic biomarkers of apoptosis and survival, p53-Bax axis and B-cell lymphoma 2 (Bcl-2) in an animal model of acetaminophen-induced acute liver injury via the ass...
