In this review I report evidence that the mainstream field of oxidative damage biology has been running fast in the wrong direction for more than 50 years. Reactive oxygen species (ROS) and chronic oxidative changes in membrane lipids and proteins found in many chronic diseases are not the result of accidental damage. Instead, these changes are the result of a highly evolved, stereotyped, and p...

enhanced oxidative stress in diabetes mellitus may contribute to the pathogenesis of diaetic complications. in this article, the stress oxidative generation has been studied in experimental diabetes by ferric reducing ability of plasma assay, a sensitive and simple method, and by other oxidative damage markers. the ferric reducing ability of plasma values as a total antioxidant capacity were si...

mycophenolate mofetil (mmf) is a selective inhibitor of inosine-5′-monophosphate dehydrogenase. gastrointestinal (gi) disturbances in immature ones are reported for mmf-induced compilations, which in the case of occurrence dose reduction is required. thus, in the present study, the fructooligosaccharide raftilose® (rft) was co-administrated with mmf to estimate the protective effect of rft agai...

nigella sativa (ns) ( ranunculaceae ) used as a protective and therapeutic traditional medicine. this study evaluates the effect of ns on inflammation-induced myocardial fibrosis, serum and tissue inflammatory markers, and oxidative stress status in male rats. fifty male wistar rats were divided into five groups: (1) control; (2) lipopolysaccharide (lps), 1 mg/kg/day; (3) lps + ns (hydroalcohol...

increased serum uric acid is known to be a major risk related to the development of several oxidative stress diseases. the aim of this study was to investigate the effect of parsley, quercetin and kaempferol on serum uric acid levels, liver xanthine oxidoreductase activity and two non-invasive biomarkers of oxidative stress (total antioxidant capacity and malondialdehyde concentration) in norma...

it has already been reported that muscle necrosis induced by various phenylenediamine derivatives are correlated with their autoxidation rate. now in a more detailed investigation of the cytotoxic mechanism using a model system of isolated hepatocytes and ring-methylated structural isomer durenediamine (dd) we have shown that under aerobic conditions, phenylenediamine induced cytotoxicity and r...

background: arsenic is one of the most toxic metalloids. anemia and leukopenia are common results of poisoning with arsenic, which may happen due to a direct hemolytic or cytotoxic effect on blood cells. the aim of this study was to examine the effects of hydroalcoholic extract of nasturtium officinale on blood cells and antioxidant enzymes in rats exposed to sodium (meta)arsenite. methods: 32 ...
