conclusions the nps-induced ots may increase the pro-inflammatory responses. on the other hand, administration of antioxidants such as nac and vitamin c and e prior to exposure to metal nps significantly decreases ots conditions. evidence acquisition here, a nanotechnology approach is evaluated using nps in human neuronal protection against ots. it may be wide therapeutic applications in the ca...

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...

many studies indicate that oxidative stress is involved in the pathophysiology of neurodegenerative diseases. oxidative stress can induce neuronal damages, modulate intracellular signaling and ultimately leads to neuronal death by apoptosis or necrosis. to review antioxidants preventive effects on oxidative stress and neurodegenerative diseases we accumulated data from international medical jou...

Numerous studies suggest that proteasome inhibition may play a causal role in mediating the increased levels of protein oxidation and neuron death observed in conditions associated with oxidative stress. In the present study we demonstrate that administration of non-toxic levels of oxidative stress does not result in impairment of 20S/26S proteasome activity, and actually increases the expressi...

Oxidative stress is critically involved in a variety of diseases. Reactive oxygen species (ROS) are highly toxic molecules that are generated during the body's metabolic reactions and can react with and damage some cellular molecules such as lipids, proteins, or DNA. Liver is an important target of the oxidative stress because of its exposure to various prooxidant toxic compounds as well as of ...

background antioxidant effects of propofol (2, 6-diisopropylphenol) were evaluated against cisplatin-i‎nduced oxidative stress in rat. objectives in this experimental study, 20 male rats were equally divided into 4 groups (5 rats each), and were treated by propofol (10 mg/kg/day, ip), or cisplatin (7 mg /kg/day, ip), or both. conclusions it is concluded that oxidative ‎damage is the mechanism o...

chloroacetaldehyde (caa) is a chlorination by-product in finished drinking water and a toxic metabolite of a wide variety of industrial chemicals (e.g. vinyl chloride) and chemotherapeutic agents (e.g. cyclophosphamide and ifosfamide). in this research, the cytotoxic mechanisms of caa in freshly isolated rat hepatocytes were investigated.caa cytotoxicity was associated with reactive oxygen spec...

Many studies indicate that oxidative stress is involved in the pathophysiology of neurodegenerative diseases. Oxidative stress can induce neuronal damages, modulate intracellular signaling and ultimately leads to neuronal death by apoptosis or necrosis. To review antioxidants preventive effects on oxidative stress and neurodegenerative diseases we accumulated data from internatio...

Objective(s): Oxidative stress and apoptosis are the major side effects of doxorubicin (DOX) and the advantages accruing fromexercise and some medicinal herbs in mitigation of these toxic side effects is well documented. But so far, the effects of exercise in combination with medicinal nanoparticles on oxidative stress and apoptosis signaling simultaneously, in liver tissue are unknown. Hence, ...
