UNLABELLED Medicinal plants are presumed to be natural sources of antioxidants that protect organisms from oxidative stresses. The present investigation aims to study the anti-oxidative stress activity of the Stachys lavandulifolia (S. lavandulifolia) plant. This trial was conducted on 26 healthy human subjects. The study was done in a before after fashion. The included subjects were asked to c...

The complication of asthma during pregnancy is associated with a number of poor outcomes for the mother and fetus. This may be partially driven by increased oxidative stress induced by the combination of asthma and pregnancy. Asthma is a chronic inflammatory disease of the airways associated with systemic inflammation and oxidative stress, which contributes to worsening asthma symptoms. Pregnan...

Background: The present study was undertaken in patients of carcinoma cervix to evaluate the Implication of chemo radiotherapy on status of oxidative stress biomarker such as protein carbonyl, lipid hydro peroxide and antioxidants defence mechanism of melatonin and total thiol levels. Methodology: Patients were delivered radiotherapy by external beam radiotherapy (EBRT) followed by brachytherap...

The reduction of oxidative stress could be achieved in three levels: by lowering exposure to environmental pollutants with oxidizing properties, by increasing levels of endogenous and exogenous antioxidants, or by lowering the generation of oxidative stress by stabilizing mitochondrial energy production and efficiency. Endogenous oxidative stress could be influenced in two ways: by prevention o...

BACKGROUND In the recent years, various studies have shown a link between the free radicals, antioxidants and periodontal diseases. The purpose of the present study was to evaluate the oxidative stress and the antioxidant status present in the gingival tissue and plasma of patients with chronic periodontitis and to evaluate the antioxidant property of taurine. MATERIALS AND METHODS Periodonta...

—All vertebrates must contend with an increase in oxidative stress during intense exercise. Birds, in particular, may be exposed to increased oxidative stress during long-distance migration, and dietary antioxidants are likely important in alleviating the deleterious effects associated with such a stressor. We evaluated whether fruit selection by birds at a migratory stopover site in southern N...

Few protein biomarkers for oxidative stress have been reported. In this study, we attempted to identify the proteins selectively overexpressed in human colon tumor cells by treating with hydrogen peroxide as oxidative stress. A proteomic analysis followed by western blotting showed that phosphoglycerate kinase 1 (PGK1) was induced by hydrogen peroxide in a dose-dependent manner, while its expre...

Strenuous physical activity is known to generate reactive oxygen species to a point that can exceed the antioxidant defense system and lead to oxidative stress. Dietary intake of antioxidants, plasma enzymatic (superoxide dismutase, glutathione reductase [Gr], and glutathione peroxidase [GPx]) activities, nonenzymatic (total antioxidant status [TAS], uric acid, alpha-tocopherol, retinol, alpha-...

the number of patients with end-stage renal disease is growing rapidly in asia. patients with end stage renal disease failure (esrd) undergoing long term hemodialysis (hd) are at risk for high oxidative stress. there is paucity of information with regard to oxidative stress during hd. therefore, the aim of the present study was to evaluate catalase enzyme activity in erythrocytes and the total ...

Lipofundin is a lipid rich emulsion used in parenteral nutrition. It is known that Lipofundin induces an oxidative stress state characterized by an increase of lipid peroxidation and a dramatic depletion of antioxidants. The aim of the present study was to evaluate the effects of an aqueous extract of Mangifera indica L., on Lipofundin-induced oxidative stress. Male Sprague Dawley rats were tre...
