in determining the physiological or physio-pathological function of oxygen reactive spices. Release of reactive oxygen species (ROS) in dermal wounds, leads to necrosis as well as apoptosis and tissue loss. Management of the risk factors for tissue loss due to flap failure can reduce risk factors with resultant improvement in the survival and efficacy of the flaps. Materials and Methods: 40 Spr...
Constantly growing body of evidence suggests that hallmarks of oxidative stress are present in various central nervous system (CNS) disorders. Technological advantages in cell culturing made it possible to use neural cell/tissue cultures as experimental models for investigation of molecular mechanisms which underlie the development of oxidative stress condition, damage and adaptive responses to...
Background and Aims: Diazinon is an organophosphate insecticide that causes oxidative stress. However, physical activity improves the antioxidant status of the heart. The present study aimed to investigate the effect of an eight-week high-intensity interval training (HIIT) on the indices of oxidative stress in the heart tissue in male rats exposed to diazinon. Materials and Methods: In this ex...
Introduction: Today, skin flaps are used in many reconstructive surgeries and healing of skin lesions as one of the main methods of treatment. Despite improvements in the fields related to enhancement of skin flap survival, flaps viability and their efficacy are still threatened with issues such as ischemia-reperfusion, oxidative stress, tissue necrosis, and even apoptosis in the affected tissu...
Background: Studies have shown that organophosphorus pesticides such as malathion induces oxidative stress injury and tissue damage. Objectives: This research aimed to determine the effects of the hydroalcoholic extracts of Satureja avromanica (SA) on the liver function of malathion-poisoned animals. Methods: Twenty-eight rats were divided into four groups of the control, SA (20 mg/kg), mala...
Many studies have shown that the pathogenesis of liver injury includes oxidative stress. MicroRNA-122 may be a marker for the early diagnosis of drug-induced liver injury. However, the relationship between microRNA-122 and oxidative stress in anti-tuberculosis drug-induced liver injury remains unknown. We measured changes in tissue microRNA-122 levels and indices of oxidative stress during live...
Markers of oxidative damage have been detected in brain tissue from patients with Alzheimer disease (AD) and other neurodegenerative disorders. These findings implicate oxidative injury in the neurodegenerative process, but whether oxidative stress is a cause or a consequence of neurotoxicity remains unclear. We used a Drosophila model of human tauopathies to investigate the role of oxidative s...
Introduction: Chronic hyperglycemia is associated with an increase in cellular damage due to oxidative stress in pancreatic tissue. The effect of exercise in different phases of the circadian cycle on protecting pancreatic tissue from oxidative stress in diabetic patients is unknown. The aim of this study was to investigate the effect of eight weeks of endurance training in light and dark phase...
introduction: electromagnetic fields (emfs) can influence the biological system by the formation of free radicals in cells. the emfs are able to deteriorate defense system against free radicals that leads to oxidative stress (os). lipid peroxidation process (lpo) is an index of oxidative stress, and the malandialdehyde (mda) is the final product of lpo. vitamin e is the most important antioxida...
Introduction: Colon cancer is the fourth cause of mortality at the world and second common cancer in the Europe. About 8% of all cancer deaths are due to colon cancer. This condition is caused by abnormal growth of cells which can invade or multiply in other tissues of the body (metastasis). The present study was designed to investigate the Simultaneous effect of quercetin and exercises on oxid...
