We have previously shown that acrolein, a lipid peroxidation byproduct, is significantly increased following spinal cord injury in vivo, and that exposure to neuronal cells results in oxidative stress, mitochondrial dysfunction, increased membrane permeability, impaired axonal conductivity, and eventually cell death. Acrolein thus may be a key player in the pathogenesis of spinal cord injury, w...
Kidney ischemia/reperfusion injury emerges in various clinical settings as a great problem complicating the course and outcome. Ischemia/reperfusion injury is still an unsolved puzzle with a great diversity of investigational approaches, putting the focus on oxidative stress and mitochondria. Mitochondria are both sources and targets of ROS. They participate in initiation and progression of kid...
Given that oxidative stress is an inherent response to burn injury, it is puzzling as to why investigation into anti-oxidant therapy as an adjunct to burn treatment has been limited. Both the inflammatory response and the stress response to burn injury involve oxidative stress, and there has been some limited success in studies using gamma tocopherol and selenium to improve certain consequences...
A variety of human disorders, e.g., ischemic heart disease, stroke, kidney disease, eventually share the deleterious consequences of a common, hypoxic and oxidative stress pathway. In this review, we utilize recent information on the cellular defense mechanisms against hypoxia and oxidative stress with the hope to propose new therapeutic tools. The hypoxia-inducible factor (HIF) is a key player...
Persistent inflammation and the generation of reactive oxygen and nitrogen species play pivotal roles in tissue injury during disease pathogenesis and as a reaction to toxicant exposures. The associated oxidative and nitrative stress promote diverse pathologic reactions including neurodegenerative disorders, atherosclerosis, chronic inflammation, cancer, and premature labor and stillbirth. Thes...
OBJECTIVE Neuropathy is a frequent and severe complication of diabetes. Multiple metabolic defects in type 2 diabetic patients result in oxidative injury of dorsal root ganglia (DRG) neurons. Our previous work focused on hyperglycemia clearly demonstrates induction of mitochondrial oxidative stress and acute injury in DRG neurons; however, this mechanism is not the only factor that produces neu...
Protective Effect of Puerarin Against Oxidative Stress Injury of Neural Cells and Related Mechanisms
BACKGROUND Parkinson's disease (PD) is manifested as degeneration of dopaminergic neurons in substantia nigra compacta. The mitochondrial dysfunction induced by oxidative stress is believed to a major cause of PD. Puerarin has been widely applied due to its estrogen nature and anti-oxidative function. This study thus investigated the protective role of puerarin against oxidative stress injury o...
occupational exposure to toluene is associated with development and progression of renal failure. however, the cellular mechanisms by which these agents cause renal dysfunction and injury remain elusive. the present study investigates the effect of toluene on animal model (rat) kidney to present a broader understanding of the mechanism by which toluene causes renal injury. adult male rats recei...
Brain injury comes from various pathological conditions. Among those, acute brain injuries such as trauma and ischemia are mainly caused in the oxidative stress of brain cells [1-3]. Labile zinc accumulation in the brain significantly contributes to oxidative brain injury [4-8]. On the other hand, neurodegenerative diseases including amyotrophic lateral sclerosis (ALS), Parkinson’s (PD), Alzhei...
Introduction: During hemorrhagic shock (HS), the kidneys are one of the primary target organs involved. Oxidative stress is shown to be enhanced in different models of acute kidney injury (AKI). Remote ischemic preconditioning (RPC) by brief limb ischemia is considered to be a safe method to protect different organs from further damage. In this study, we investigated the effects of brief hind l...
