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...
During normal cell respiration, approximately 0.1–0.2% of the oxygen consumed by aerobic cells is converted into reactive oxygen species (ROS), due to the uncompleted reduction of molecular oxygen in the mitochondrial electron transport chain [1]. ROS includes the superoxide anion radical (O2·), hydrogen peroxide (H2O2), alkyl peroxides, singlet oxygen (O2) and the hydroxyl radical (·OH). They ...
We defined the basal levels of reactive oxygen species (ROS) in normal donors in neat (whole unprocessed) semen specimens, and in mature and immature spermatozoa isolated by a double-density gradient technique. In addition, we demonstrated that the ROS levels were significantly lower in neat semen compared with washed spermatozoa. The reference values of ROS in neat semen and mature spermatozoa...
