O 22: Reactive Oxygen Species and Epilepsy
Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...

متن کاملI-3: Reactive Oxygen Species: A Dilemma for
Spermatozoa are very special cells and constantly exposed to the interphase between oxidative stress through high amounts of reactive oxygen species (ROS) and leukocytes, and reduction by means of scavengers and antioxidants. Considering the very special functions of spermatozoa as being the only cells with such high polarization and exerting their functions outside the body, even in a differen...
متن کاملTimeline: Cellular Oxygen Sensing
Since the 1950s, researchers have recognized that red blood cell numbers expand or contract as needed, according to the amount of available oxygen. The later discoveries that erythropoietin and VEGF levels adapt to oxygen levels launched a new field aimed at understanding how cells sense and respond to normal- and low-oxygen environments. The 2016 Albert Lasker Basic Medical Research Award reco...
متن کاملCellular thiols and reactive oxygen species in drug-induced apoptosis.
In higher eukaryotes, reactive oxygen species (ROS) are generated during respiration in mitochondria in the course of reduction of molecular oxygen as well as by distinct enzyme systems. ROS have been implicated in the regulation of diverse cellular functions including defense against pathogens, intracellular signaling, transcriptional activation, proliferation, and apoptosis. The reduction-oxi...
