schizophrenia is a chronic and often debilitating illness which affects about 1% of the world population. some reagents have been used to simulate schizophrenic disorders in laboratory animals, such as amphetamine and ketamine. previous studies have suggested that reactive oxygen species (ros) production, reduced levels of atp, mitochondrial dysfunction and apoptosis are involved in the pathoph...

The endogenous reactive oxygen species ("ROS") formation is associated with many pathologic states such as inflammatory diseases, neurodegenerative diseases, brain and heart ischemic injuries, cancer, and aging. The purpose of this study was to investigate the endogenous sources for "ROS" formation in intact isolated rat hepatocytes, in particular, peroxisomal oxidases, monoamine oxidase, xanth...

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...

objective: oxidative stress as a consequence of aging can induce infertility in males. in this study, we have investigated the effects of aging on sperm parameters, intra-spermatic water soluble antioxidants, reactive oxygen species (ros), and in vitro blastocyst formation. methods: we chose 5 older nmri male mice (10-12 months) and 5 younger nmri male mice (2-3 months). sperm parameters, ros, ...

isolated rat hepatocytes in culture were incubated with different concentrations of iron-sorbitol (50, 100, 150, and 200 µm) to assess the changes in reactive oxygen species (ros) and lipid peroxidation leading to apoptotic hepatocyte cell death. the viability of hepatocytes was declined depending on the iron concentration. one hour incubation of the cells with 100 µm iron resulted in decreased...

arsenic exposure mainly through food and water has been shown to be associated with increased incidence of numerous cancers and non-cancer harmful health. it is also used in cancer chemotherapy and treatment of several cancer types due to its apoptogenic effects in the various cancer and normal cell lines. we have already reported that liver is the storage site and important target organ in as ...
