The prevention of oxidation is an essential process in all cells, as decreased antioxidant protection may lead to cytotoxicity, mutagenicity and carcinogenicity. The mechanisms by which oxidative stress contributes to carcinogenesis include modulation of gene expression and induction of genetic modifications. Cellular methylation and antioxidant metabolism are linked by the transsulfuration pat...

background free radicals are known as atoms and molecules which are highly reactive with the body’s single-electrons, and may cause irrecoverable damages to the macromolecules of organisms. systems to deal with damages caused by free radicals are known as “antioxidant immune systems”. flavonoids and polyphenolic compounds are from non-enzymatic antioxidants which many nutritional compounds cont...

Objective Indiscriminate use of synthetic pyrethroid insecticides, Cypermethrin (Cyp) and Deltamethrin (Del) have been reported to cause system toxicity in mammals including humans. The dietary antioxidants protects tissues and organs against insecticides/xenobiotic induced damage. In present study, we evaluated the effect of exposure of Cyp and Del and possible protective roles of curcumin and...

Purslane(Portulaca oleracea L.) is a local plant in Iran that can easily breed. Chromium is a heavy metal that causes toxicity for the growth and development of plants. To study the effects of  potassium dichromate on growth, efficiency of photosystem II (Fv/Fm), cell membrane stability index (MSI), indexes of oxidative stress and antioxidant properties of purslane, an experiment was d...

Mucuna pruriens Linn., a leguminous plant, has been recognized as an aphrodisiac and spermatogenic agent. Protective efficacy of M. pruriens on reactive oxygen species (ROS)-induced pathophysiological alterations in structural and functional integrity of epididymal sperm in aged Wister albino rat was analysed. Animals were grouped as groups I, II, III and IV, i.e. young (control), aged, aged tr...
