introduction: acrylamide (acr) known as a neurotoxic agent in human and animals. previous studies have been shown; fasudil improves neurological deficit and neuronal damage. in this study, the effect of fasudil, potent rho-kinase inhibitor, on acr-induced cytotoxicity was evaluated using pc12 cells as a suitable in vitro model. materials and methods: pc12 cells were exposed to different concent...

conclusions hemodialysis exacerbates oxidative stress and conformational changes of hb in patients with diabetes on hemodialysis. the frap value can be used as a positive determinant, while pco and hb derivatives can be used as negative determinants of oxidative stress in patients with diabetes. background diabetes is associated with an increased generation of reactive oxygen species (ros), whi...

objective: hexavalent chromium [cr (vi)] compounds are well-known environmental contaminants  generated from industrial processes. several studies have reported the harmful effects of cr (vi) on different organs, however, little is known about neurotoxic effects of cr (vi). the aim of this study is to investigate the toxic effects of cr (vi) on pc12 cells. methods: pc12 cells were cultured foll...

Neuronal degeneration due to oxidative stress (OS) has been proposed as a mechanism for tardive dyskinesia (TD) pathogenesis. Cellular defense mechanisms against OS may involve detoxification enzymes (e.g., glutathione peroxidase-1, GPX1; superoxide dismutase-2, SOD2 [also commonly known as MnSOD]; and glutathione S-transferase P1, GSTP1). Several pharmacogenetic studies have examined TD and OS...

Aromatic triazoles are known to be effective antifungal agents. The generally accepted mode of action entails inhibition of ergosterol in the membrane. A hypothesis is presented herein based on Electron Transfer (ET), Reactive Oxygen Species (ROS) and Oxidative Stress (OS) which may be a unifying mechanism. Many substances in vivo are known to operate in a multifaceted manner. A prior article p...

Hemodialysis (HD) patients are at high risk for all-cause mortality and cardiovascular events. In addition to traditional risk factors, excessive oxidative stress (OS) and chronic inflammation emerge as novel and major contributors to accelerated atherosclerosis and elevated mortality. OS is defined as the imbalance between antioxidant defense mechanisms and oxidant products, the latter overwhe...

Recent meta-analysis shows that adherence to a Mediterranean diet (MD) can significantly decrease the risk of overall mortality, mortality from cardiovascular diseases, as well as incidence of mortality from cancer, and incidence of Parkinson's and Alzheimer's disease. All of these diseases could be linked to oxidative stress (OS) as antioxidative effect of MD is getting more attention nowadays...

Prostatic hyperplasia (PH) is a common urologic disease that affects mostly elderly men. PH can be classified as benign prostatic hyperplasia (BPH), or prostate cancer (PCa) based on its severity. Oxidative stress (OS) is known to influence the activities of inflammatory mediators and other cellular processes involved in the initiation, promotion and progression of human neoplasms including pro...

Oxidative stress (OS) has been linked to the etiology and development of leukemia as reactive oxygen species (ROS) and free radicals have been implicated in leukemogenesis. OS has beneficial and deleterious effects in the pathogenesis and progression of leukemia. High-dose chemotherapy, which is frequently used in leukemia treatment, is often accompanied by ROS-induced cytotoxicity. Thus, the u...

Introduction: Parkinson’s disease (PD) is a neurological disorder associated with the selective loss of dopaminergic (DAergic) neurons. Clinical data suggest that oxidative stress (OS) and dysregulation of glucose (G) metabolism are early events in PD. However, no data are available to explain the molecular connection between glucose metabolism, OS, and neuronal demise in PD. Human lymphocytes ...
