BACKGROUND Oxidative stress and endoplasmic reticulum (ER) stress play a crucial role in tubular damage in both acute kidney injury (AKI) and chronic kidney disease (CKD). While the pathophysiological contribution of microRNAs (miRNA) to renal damage has also been highlighted, the effect of miRNA on renal damage under oxidative and ER stresses conditions remains elusive. METHODS We assessed c...

Oxidative Stress is implicated as one of the primary factors that contribute to the development of neurodegenerative diseases like Alzheimer's Disease, Parkinsonism and neurological conditions like epileptic seizures, stroke, brain damage, neurotrauma etc. The increased formation and release of oxygen free radicals coupled with the rather low antioxidative potential of the central nervous syste...

Abstract: Background and Objectives: Myocardial ischemia is one of the leading causes deaths among cardiac pathological conditions. Doxorubicin belongs to anthracycline class drug which effective against a wide variety neoplasms. However, doxorubicininduced cardiotoxicity limits clinical utility drug. One major myocardial oxidative stress. Adhatoda vasica have been shown possess strong anti-inf...

cognitive deficits have been observed in patients with multiple sclerosis (ms) because of hippocampal insults. oxidative stress plays a key role in the pathophysiology of ms. the aim of this study was to evaluate the effects of crocus sativus l., commonly known as saffron, on learning and memory loss and the induction of oxidative stress in the hippocampus of toxic models of ms. one week after ...

background and aims:in neurodegenerative disorders,oxidative stress mediated by reactive oxygen species is strongly associated with increased neuronal damages which can lead to apoptosis. pro-apoptotic and anti-apoptotic gene expressions are changed during the cell differentiation that affect cell viability and differentiation. therefore, this study was conducted to determine the effects of hyd...

Obesity is a main reason of type 2 diabetes and also chronic exposure to arsenic (As)can produce diabetic symptoms. In previous studies, the association between high-fat dietand arsenic in the incidence of diabetes was found, but the role of beta cells activity, livermitochondrial oxidative stress, and hepatic enzymes (leptin, adiponectin and beta amylase)was unclear. Thus, present study was co...

BACKGROUND AND OBJECTIVES The risk of non-Hodgkin's lymphoma (NHL) has been associated with inflammation. One possible mechanism may involve oxidative stress as reactive oxygen species (ROS) can generate pro-inflammatory signals. Anti-oxidant enzymes including superoxide dismutase, glutathione peroxidase and catalase protect against the harmful effects of ROS. Genetic variation in the genes cod...

AIM To determine whether cigarette smoking, as a risk factor for CAD, affects (anti)oxidant status. MATERIAL AND METHODS The study included patients with CAD, divided according to their smoking status and the number of cigarettes smoked during a day. Biological markers of oxidative stress (concentration of oxidants and activity of antioxidant enzymes) were measured in all subjects. RESULTS ...

In our previous work, the ethanolic extract of Panax ginseng C. A. Meyer was successively partitioned using supercritical carbon dioxide at pressures in series to yield residue (R), F1, F2, and F3 fractions. Among them, F3 contained the highest deglycosylated ginsenosides and exerted the strongest antioxidant and anti-inflammatory activities. The aim of this study was to investigate the protect...

Cold and immobilization stressors can generate oxidative stress as well as skeletal muscle fatigue. Free radicals cause oxidative degradation of lipids, proteins, nucleic acids, and carbohydrates molecules thereby compromising cell integrity and function. Coturnix japonica (quail) egg had been described as being very functional biochemically, due to the essential biomolecules it contains in ver...
