Superoxide dismutases (SODs) are important antioxidant enzymes that play a crucial role in protecting organisms from...

... damage. Although carotenoid levels did not differ between annuals and perennials, we found that deciduous perennials had higher activity of the ascorbate–glutathione cycle, and evergreen perennials had higher activity of superoxide dismutase (SOD, EC 1.15.1.1). The second hypothesis was that chlorophyll...

We reported that FTM increased with age from juvenile to adulthood for both sexes, with higher FTM concentrations in males than females...

... as a potential source of skin-lightening compounds. Vitamin C (Vc) and superoxide dismutase (SOD)-rich extracts were extracted from RR, namely RRVC and RRSOD, using macroporous resin column chromatography and graded ammonium sulfate precipitation. The antioxidant and skin-lightening effects of these extracts...

... at the transcriptional level possibly due to increased DNA methylation. Among these, superoxide dismutase 1 was down-regulated, and reactive oxygen species (ROS) levels increased in the mouse heart. Inhibition of ROS generation using the antioxidant N-acetylcysteine rescued the impaired cardiac function resulting from...

... of the most important effects of ZEA is the induction of oxidative stress, which leads to physiological and behavioral changes. This study deals with the effects of high doses of ZEA (10 and 20 mg/kg) on survival, molting, growth, weight gain, activity of antioxidant enzymes superoxide dismutase (SOD...
