In the developing embryo and fetus, endogenous or xenobiotic-enhanced formation of reactive oxygen species (ROS) like hydroxyl radicals may adversely alter development by oxidatively damaging cellular lipids, proteins and DNA, and/or by altering signal transduction. The postnatal consequences may include an array of birth defects (teratogenesis), postnatal functional deficits, and diseases. In ...

background: our purpose was to investigate propolis and its component caffeic acid phenethyl ester (cape) for their antioxidant effects on the brain tissue of rats exposed to ionizing radiation (ir). materials and methods: fifty-four male albino sprague-dawley rats, divided into six groups, were designed as normal control group, cranial irradiation of 5 gray alone, irradiation plus cape, irradi...

The present study is focused on the importance of SNP, a NO donor, as Cd stress modulator on seedlings of cabbage. The exogenously applied Cd induced stress in cabbage seedlings to explore the protective role of SNP. 21-day-old seedlings were grown in Hoagland solution and Cd at 0.5 and 0.7 mM concentration with and without SNP. The biophysical and biochemical parameters were analyzed. Cd exhib...

preliminary investigation on antioxidative potentials of defatted fermented locust bean extract in comparison to defatted non-fermented locust bean was conducted. qualitative antioxidative assessment on the extract was accomplished by screening the phytochemical endowment, and similar bioactive components. also some antioxidative indices were quantitatively evaluated. results showed that the de...
