Rol antioxidante de la L-carnitina en un modelo experimental de estrés oxidativo inducido por consumo elevado de fructosa

RESUMEN Objetivos: Evaluar el rol de la L-carnitina (LC) sobre el estrés oxidativo inducido por fructosa en ratas Holtzman. Materiales y métodos: Se realizó un estudio experimental durante 56 días, con cuatro grupos: control, control+LC, fructosa y fructosa+LC. Los grupos con fructosa recibieron e...

Histomorphometric and immunohistochemical evaluation of the frontal cerebral cortex in diabetic rats after treatment with melatonin

Pesqui. vet. bras; 40 (12), 2020
The central nervous system is vulnerable to complications caused by diabetes. These complications lead to increased oxidative stress in the brain, resulting in damage to the cerebral cortex, among other regions. Insulin and hypoglycemic agents are still the most widely used treatments. However, current r...

Ácido úrico y gamma-glutamiltransferasa como biomarcadores de enfermedad cardiovascular a través del estrés oxidativo
Uric acid and gamma-glutamyltransferase as biomarkers of cardiovascular disease via oxidative stress

Introducción: Las enfermedades cardiovasculares constituyen la principal causa de mortalidad y morbilidad a nivel mundial. Reconocidas como problemas de salud de impacto social, han motivado a muchos científicos a tratar de explicar su patogénesis. Actualmente se plantea de la existencia de otros fac...

Estresse oxidativo e diminuição de HSP70 tecidual envolvidos na gênese da sepse: HSP70 como alvo terapêutico

RESUMO A sepse é uma infecção sistêmica que acarreta disfunção múltipla dos órgãos. A HSP70 é uma proteína responsiva ao estresse celular, assim como o estresse oxidativo. Esta revisão da literatura buscou investigar a HSP70 e o estresse oxidativo quanto à fisiopatologia da sepse e ao papel ...

Antioxidant activity of selenium on bisphenol-induced apoptosis and testicular toxicity of Albino rats

Int. j. morphol; 38 (6), 2020
SUMMARY: Bisphenol A (BPA) is an industrial chemical widely used to make polycarbonate plastics for packaging and epoxy resins. This study sought to examine how selenium (Se) affects BPA toxicity in terms of albino rats' histological structure, antioxidant enzymes and reproductive organs (seminiferous tu...

Vitamin D deficiency is not associated with increased oxidative stress in chronic kidney disease pre-dialysis patients

J. bras. nefrol; 42 (4), 2020
Abstract Introduction: The progressive decline in 25-hydroxyvitamin D [25(OH)D] in chronic kidney disease (CKD) limits the kidney ability of synthesizing the vitamin. Vitamin D deficiency as defined by KDIGO (25(OH)D <20 ng/mL) is prevalent in CKD patients and associated to oxidative stress (OS). We ...

Effects of yacon flour associated with an energy restricted diet on intestinal permeability, fecal short chain fatty acids, oxidative stress and inflammation markers levels in adults with obesity or overweight: a randomized, double blind, placebo controlled clinical trial

ABSTRACT Objectives Yacon flour is rich in bioactive compounds (phenolic compounds and fructooligosaccharides (FOS)), and may therefore reduce the risk of diseases associated with excess body weight. However, its effect on fecal short chain fatty acids (SCFA), intestinal permeability, oxidative stress ...

Induction of brain injury and depression in rats by chronic unpredictable stress associated with the augmentation of nitrosative stress and apoptosis

Int. j. morphol; 38 (5), 2020
SUMMARY: Repeated stress is a risk factor for memory impairment and neurological abnormalities in both humans and animals. We sought to investigate the extent of (i) brain tissue injury; (ii) nitrosative and oxidative stress in brain tissue homogenates; (iii) apoptotic and survival biomarkers in brain ti...

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...
