background: oxidative stress reflects an imbalance between the reactive oxygen species (ros) and a biological system's ability to readily detoxify the oxidative agents. disturbances in the normal redox state of cells can cause toxic effects through production of peroxides and free radicals that damage all components of the cell, including proteins, lipids, and dna. objectives: the purpose ...

Methylsulfonylmethane (MSM) is a sulfur-containing compound commonly found in diet and known to reduce oxidative stress. This trial was conducted to determine whether single dose supplementation with MSM attenuates post-exercise oxidative stress in healthy untrained young men. Sixteen untrained men volunteered for this study. Participants were randomized in a double-blind placebo-controlled fas...

 Background and Objective: Diabetes mellitus accompanies enhanced oxidative stress and decreased activity of antioxidant defense system. Due to the significant role of enhanced oxidative stress in development of renal damage and nephropathy in diabetes and with regard to antidiabetic and antioxidant effect of apigenin, this study was conducted to evaluate the effect of this flavonoid on ...

Introduction: Chronic diabetes mellitus in the long run accompanies enhanced oxidative stress burden and decreases activity of antioxidant defense system. Due to significant role of these factors in development of some neurological disorders and with regard to antidiabetic and antioxidant effect of Tribulus terrestris (TT), this study was conducted to evaluate the effect of its oral administrat...

Introduction: Aging is the major risk factor for neurodegenerative diseases and oxidative stress is involved in the pathophysiology of these diseases. Oxidative stress can induce neuronal damages and modulate intracellular signaling, ultimately leading to neuronal death by apoptosis or necrosis. Methods: In this study, we investigated the possible antioxidant and neuroprotective properties o...

ZnO NPs (zinc oxide nanoparticles) has generated significant scientific interest as a novel antibacterial and anticancer agent. Since oxidative stress is a critical determinant of ZnO NPs-induced damage, it is necessary to characterize their underlying mode of action. Different structural and physicochemical properties of ZnO NPs such as particle surface, size, shape, crystal structure, chemica...

Background & Aim: The most common primary brain tumors of the central nervous system are gliomas. Among a number of different biomolecular events, a strong relation between oxidative stress pathways and the development of this cancer has been proved. Oxidative stress (OS) is the consequence of an imbalance between pro-oxidants and antioxidants towards pro-oxidants. The pro-oxidants cause lipid ...

Background and Objectives: Reactive oxygen species (ROS) are essential for sperm physiological functions including capacitation, acrosome reaction, fertilization, and etc. Sperm cell in comparison with other cells is highly prone to oxidative attack due to high level of membrane unsaturated fatty acids and low volume of cytoplasmic space. Therefore, the aim of this review article was to underst...

Background: Chronic diabetes mellitus is accompanied with enhanced oxidative stress and reduce the activity of antioxidant defense system. Due to significant role of enhanced oxidative stress in development of testes damage in diabetices, this study was conducted to evaluate the effect of royal jelly on oxidative stress marker in testis tissue of diabetic rats. Materials and Methods: In this ex...
