Metabolic changes during the development and maturation of Triticum durum Desf. (L.) kernels were studied, with particular emphasis on changes in the redox state of ascorbate and glutathione, as well as in the activities of the enzymes responsible for the recycling of their oxidized forms (ascorbic free radical reductase, EC 1.6.5.4; dehydroascorbate reductase, EC 1.8.5.1; glutathione reductase...

Introduction: Huntington's disease is a neurodegenerative disorder in which an increase in the global oxidative stress and a decrease in the antioxidant defense system are observed. Olea europaea's main phenolic components include oleuropein, dimethyl oleuropein, ligstroside and phenolic oleosides, which can be more than 140 mg per gram of fresh olives and 60-90 mg per gram of dried olive le...

PURPOSE The aim of this study was to investigate the potential antioxidative effect and mechanism for the protective effects of hydrogen saline on selenite-induced cataract in rats. METHODS Sprague-Dawley rat pups were divided into the following groups: control (Group A), selenite induced (Group B), and selenite plus hydrogen saline treated (Group C). Rat pups in Groups B and C received a sin...

Heavy metals are the cause of major abiotic stresses in plants and a principal contributor to environmental pollution in recent decades. This study investigated the effects of exogenous hydrogen sulfide on the ascorbate-glutathione cycle in the leaves of coriander seedlings under copper stress. Results showed that copper stress not only reduced APX and GR activities but also decreased leaf AsA,...

15 16 The thiol-containing tripeptide glutathione is an important cellular constituent of many 17 eukaryotic and prokaryotic cells. In addition to its disulfide reductase activity, 18 glutathione is known to protect cells from many forms of physiological stress. This 19 report represents the first investigation into the role of glutathione in the Gram-positive 20 pathogen, Streptococcus pneumon...

CMV infection during pregnancy induces a number of N-nitrosation reactions in red blood cells, which violate process of normal hemoglobin oxygenation. Abnormalities in the L-arginine-NO system cause a decrease in the antioxidant capacity of red blood cells, which is associated with reducing the amount of glutathione reductase, glutathione peroxidase and superoxide dismutase.
