Bioimaging 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 کاملReactive Nitrogen Species in Motor Neuron Apoptosis
Nitric oxide is a cellular messenger produced by different cell types in an organism, both in physiological and pathological conditions (Snyder 1993; Beckman and Koppenol 1996; Beckman and Koppenol 1996; Beckman 1996; Colasanti and Suzuki 2000; Pacher, Beckman, and Liaudet 2007). Nitric oxide was first described in biology as the endothelium-derived relaxation factor for its effects on vasodila...
متن کاملMeasurement of Reactive Oxygen Species, Reactive Nitrogen Species, and Redox-Dependent Signaling in the Cardiovascular System
e39 Abstract—Reactive oxygen species and reactive nitrogen species are biological molecules that play important roles in cardiovascular physiology and contribute to disease initiation, progression, and severity. Because of their ephemeral nature and rapid reactivity, these species are difficult to measure directly with high accuracy and precision. In this statement, we review current methods fo...
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,...
