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...
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...
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...
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 ...
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...

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 ...
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 ...
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...
