Objectives: Immobilization effects on antioxidant enzymes activities, red-ox variables and rheological parameters of erythrocytes were studied. Background: It is not clear to which extent immobilization-induced oxidative stress may affect erythrocyte rheology. Method: Hematological and red-ox variables, erythrocyte antioxidant enzymes activities, and rheologic parameters of erythrocytes were an...

Antioxidant enzymes protect cells against oxidative stress and are associated with stress tolerance and longevity. In animals, variation in their activities has been shown to relate to species ecology, but in plants, comparative studies with wild species are rare. We investigated activities of five antioxidant enzymes - ascorbate peroxidase (APX), catalase (CAT), glutathione reductase (GR), per...

Objective: The local thermoregulation in testis is important for optimum spermatozoa development. Excessive heat hampers this regulation resulting alteration of normal testicular function. present investigation confirms the role free radicals hyperthermia induced oxidative damage and elucidates dose-dependent ameliorating effect resveratrol (RSV) against damage. aim also to observe selective co...

The aim of the present study was to determine antioxidant defence mechanisms in the rat and Hymenolepis diminuta after long-term infestation. We determined levels of oxidative stress markers, and activity of antioxidant enzymes in the rat small intestine and in particular parts of H. diminuta. Observed changes in antioxidant enzymes activity in H. diminuta and the rat intestine indicate the def...

background: diabetes is the most common endocrine disease. it has adverse effects on male reproductive function. royal jelly (rj) has antioxidant and anti-diabetic effects and show protective effects against diabetes. objective: this study was conducted to evaluate the effect of rj on histopathological alterations of the testicular tissue in streptozotocin (stz)-induced diabetic rats. materials...

Impact of Phyllanthus amarus extract on antioxidant enzymes in Drosophila melanogaster N. Manasa, J. S. Ashadevi

BACKGROUND Several studies suggested that women may be more susceptible to oxidative damage induced by cigarette smoking, but the role of smoking status and antioxidant capacity in gender difference in susceptibility to oxidative damage has not been well studied. METHODS We conducted a cross-sectional analysis of the baseline data from 146 current and former heavy smokers enrolled in a chemop...

In sustained severe ischemia, reperfusion with oxygen carriers may result in ischemia-reperfusion injuries because of the release of damaging oxygen radicals. A nanobiotechnology-based polyhemogloin-calatase-superoxide dismutase can prevent this because the oxygen carrier, polyhemoglobin, is linked to antioxidant enzymes, catalase and superoxide dismutase. However, these antioxidant enzymes com...
