Phenolic antioxidants inhibit the induction of inflammatory cytokines by inflammatory stimuli. Here, we analyzed the mechanism by which the antioxidants inhibit LPS-induced expression of tumor necrosis factor alpha (TNFalpha) in macrophages. Hydroquinone and tert-butyl hydroquinone, prototypes of phenolic antioxidants, block lipopolysaccharide (LPS)-induced transcription of TNFalpha and a nucle...
The powerful action of antioxidants in preventing premature lipid oxidation in food suggests that the same compounds, when consumed with the daily diet, could unfold antioxidative/anti-aging effects in the human body. Therefore, it has been hypothesized that antioxidants are helpful in preventing various diseases. More detailed chemical and physiological examination of antioxidants shows, howev...
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...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
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...
