Thyroid hormone-induced haemoglobin changes and antioxidant enzymes response in erythrocytes
(John Wiley & Sons Ltd, 2011-07)
Thyroid hormones modulate haemoglobin and reactive oxygen species (ROS) production, leading to antioxidant changes. This study evaluated the antioxidant response to ROS in erythrocytes in hypothyroid and hyperthyroid rats. ...
Erythrocyte selenium concentration predicts intensive care unit and hospital mortality in patients with septic shock: a prospective observational study
(Biomed Central Ltd, 2014-01-01)
Introduction: Selenoenzymes can modulate the extent of oxidative stress, which is recognized as a key feature of septic shock. The pathophysiologic role of erythrocyte selenium concentration in patients with septic shock ...
Avaliação do status antioxidante, expressão gênica e polimorfismos dos genes SOD1, SOD2 e GPx1 em crianças, adolescentes e adultos jovens com diabetes tipo 1
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciências FarmacêuticasBioanálises e Medicamentos, 2012-02-27)
Studies report that the pathophysiological mechanism of diabetes complications is associated with increased production of Reactive Oxygen Species (ROS)-induced by hyperglycemia and changes in the capacity the antioxidant ...
Síntese e avaliação do potencial antioxidante de cumarinas funcionalizadas com selênio
(Florianópolis, SC, 2016)
Papel de la glutatión peroxidasa 2 (GPX2) en la producción mitocondrial de especies reactivas del oxígeno en el citocromo b de células de Saccharomyces cerevisiae en restricción calórica
(Universidad Michoacana de San Nicolás de Hidalgo, 2021-06)
Mitochondrial reactive oxygen species (ROS) increases with aging and this has been associated to decreased longevity. Calorie restriction (CR) is the only non - genetic manipulation that extends longevity in a wide variety ...
Testicular hyperthermia reduces testosterone concentrations and alters gene expression in testes of Nelore bulls
(2020-08-01)
Increased testicular temperature reduces sperm motility, morphology and fertility. Our objectives were to characterize effects of testicular hyperthermia (scrotal insulation) on acute testosterone concentrations and gene ...
Desbalanço superóxido-peróxido de hidrogênio versus seleno-L-metionina e castanha-do-Brasil: regulação diferencial in vitro de (seleno)enzimas
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica ToxicológicaCentro de Ciências Naturais e Exatas, 2017-08-01)
Introduction: The coupled enzymatic reactions between the manganese-dependent superoxide dismutase (MnSOD/SOD2) and selenoenzyme glutathione peroxidase-1 (GPx-1) selenoenzyme are essential for mitochondrial redox balance ...
Associação entre a concentração de selênio, o polimorfismo Pro198Leu da glutationa peroxidase 1 e a mortalidade em pacientes com choque séptico
(Universidade Estadual Paulista (Unesp), 2014-02-24)
The oxidative stress is recognized as a key feature of septic shock. In addition, in patients with systemic inflammatory response, plasma selenium concentration falls independently of selenium status. However, the ...
