parkinson`s disease (pd) is the second most common neurodegenerative disorder after alzheimer`s disease. it is a chronic and progressive disease, and mostly afflicts elderlies. pd starts with sudden onsets and the exact cause of the disease is still unknown, however there are some early symptoms that can help us to diagnose the disease and ameliorate its effects. pd is a multi-factorial disease...

The processes leading to red cell destruction in oxidant-induced hemolytic disease are not yet fully known. Oxidant damage to hemoglobin per se may be insufficient to explain the process, and the involvement of membrane damage has been suggested. We now report that at least one crucial membrane function-exclusion of calcium-is disrupted by the potent oxidant phenylhydrazine. Phenylhydrazine, bo...

introduction: the molecular mechanisms involved in pathogenesis of esophageal cancer have been the main concern of several studies. in this study, we aimed to investigate the changes of serum prooxidant-antioxidant balance (pab) value as a redox index, as well as serum c-reactive protein (crp) compared to healthy control group. materials and methods: in a cross-sectional study, blood samples we...

conclusions therefore, our results suggest that although administration of 300 mg/kg of calendula officinalis extract showed salutary effects on anti-oxidant profile, yet its protective effects on anti-diabetic and regenerative properties on nephropathy were ambiguous and require more investigations. background chronic hyperglycemia leads to microvascular and macrovascular complications such as...

Data provided by WHO show that the prevalence of aggressive periodontitis is observed in almost 19% adult world population and associated with destruction attachment apparatus premature tooth loss. Development a periodontal pocket foci infection also negatively affect body on whole. Despite great number researches this field dramatic improvement treatment prophylaxis, problem high diseases rema...

Oxidants play an important role in homeostatic function, but excessive oxidant generation has an adverse effect on health. The manipulation of Reactive Oxygen Species (ROS) can have a beneficial effect on various lung pathologies. However indiscriminate uses of anti-oxidant strategies have not demonstrated any consistent benefit and may be harmful. Here we propose that nuanced strategies are ne...

Since "free radical research" started in 1954, understanding the role of oxidants and antioxidants in physiological and pathological conditions has increased continuously. Oxidants are essentially generated by metabolic enzymes, inflammatory cells and mitochondrial electron leakage; they are indispensable for the cellular redox regulation and may, under certain conditions, have a pro-inflammato...
