Reactive oxygen species (ROS) and nitric oxide (NO) are proposed mediators of cytokine-induced beta-cell destruction in type 1 diabetes. We produced transgenic mice with increased beta-cell expression of manganese superoxide dismutase (MnSOD) and catalase. Expression of these antioxidants increased beta-cell ROS scavenging and improved beta-cell survival after treatment with different sources o...

During the space flight, the high-energy radiation in the universe may cause a number of health-relative problems such as the increased risk of cancer induction in astronauts. Recent studies have shown that a diet rich in antioxidants can mitigate the harmful effects of the radiation with high energy and particle charge during long-term space flight. Therefore, planting the vegetables rich in a...

The wistar strain male albino rats were fed with various seabuckthorn products for a period of 30 days, to determine the bioavailability of antioxidants in seabuckthorn based products (juice powder, jam, squash and fruit yoghurt) and concurrent effect on antioxidant system in rats. The excretion of antioxidants in urine and feces; availability of antioxidants in blood and tissues of liver, hear...

Recent studies contend that the skin is subject to far more damage than just ultraviolet (UV) light, with infrared radiation and pollution now clearly demonstrated to degrade cutaneous tissue. While consumers continue to strive for new ways to augment the aesthetic appeal and improve the health of their skin, awareness regarding environmental insults and effective ways to protect the skin remai...
