Applications of Electron Spin Resonance Spectrometry for Reactive Oxygen Species and Reactive Nitrogen Species Research
Electron spin resonance (ESR) spectroscopy has been widely applied in the research of biological free radicals for quantitative and qualitative analyses of reactive oxygen species (ROS) and reactive nitrogen species (RNS). The ESR spin-trapping method was developed in the early 1970s and enabled the analysis of short-lived free radicals. This method is now widely used as one of the most powerfu...
متن کاملBioimaging Probes for Reactive Oxygen Species and Reactive Nitrogen Species
Reactive oxygen species (ROS) play key roles in many pathogenic processes, including carcinogenesis, inflammation, ischemia-reperfusion injury and signal transduction. Also, reactive nitrogen species (RNS) cause various biological events such as neurodegenerative disorders. Sensitive and specific detection methods for ROS and RNS in biological samples should be useful for elucidation of biologi...
متن کاملO 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 کاملBiochemistry of Reactive Oxygen and Nitrogen Species
Reactive species or free radicals include reactive oxygen and nitrogen species that are called reactive oxygen nitrogen species. Reactive oxygen species are formed as a natural by-product of the normal metabolism of oxygen and have significant roles in cell signaling and homeostasis. The reactive oxygen species are generated as a byproduct of biochemical reactions, in mitochondria, peroxisomes,...
متن کاملInteractions between nitric oxide, oxygen, reactive oxygen species and reactive nitrogen species.
ROS (reactive oxygen species) and RNS (reactive nitrogen species) are central to the innate immunity that protects us from infection, but also contribute to degenerative diseases and possibly aging. However, ROS and RNS are increasingly recognized to contribute to physiological signalling. This review briefly describes the main interactions between ROS and RNS and shows how their origins, chemi...
