THE REACTIVE SPECIES IN ACTIVE NITROGEN
Canadian Journal of Chemistry, 1962A study has been made of the discrepancy between the N-atom content of active nitrogen as inferred from the maximum HCN production from the reaction of many hydrocarbons, and that indicated by the extent of NO destruction. The HCN production from several hydrocarbons was similar at high reaction temperatures in a spherical reaction vessel, and was ...

Carbon dots as Reactive Nitrogen Species nanosensors
Analytica Chimica Acta, 2022Three sets of Carbon Dots (Cdots) were produced through the carbohydrates acid thermal decomposition method. These nanoparticles were functionalized with a polymer, known for its biological compatibility: polyethylene glycol, PEG200, and folic acid, FA, a biomolecule associated with the reactive oxygen and nitrogen (ROS/RNS) savaging process, thus ...

Clinical aspects of reactive oxygen and nitrogen species
Biochemical Society Symposia, 2004Endothelial dysfunction in the setting of cardiovascular risk factors, such as hypercholesterolaemia, hypertension, diabetes mellitus and chronic smoking, as well as in the setting of heart failure, has been shown to be at least partly dependent on the production of reactive oxygen species in endothelial and/or smooth muscle cells and the adventitia ...

Detection of reactive oxygen and reactive nitrogen species in skeletal muscle
Microscopy Research and Technique, 2001AbstractReactive oxygen species (ROS) and reactive nitrogen species (RNS) are usually identified with pathological states and mediators of cellular injury. However, over the last decade ROS and RNS have been identified in skeletal muscle under physiological conditions.

Reactive Oxygen and Reactive Nitrogen Species in the Lung
2000Reactive oxygen species (ROS) and reactive nitrogen species (RNS) have been implicated as contributing to the pathogenesis of a broad spectrum of diseases [1, 2]. Historically, oxygen free radicals were primarily considered to be aggressive species, indeed the superoxide (O 2 .- theory of oxygen toxicity is based on this hypothesis, (reviewed in 3 ...

The interdependence of the reactive species of oxygen, nitrogen, and carbon
Journal of Physiology and Biochemistry, 2012This mini-review tries to summarize the main interdependences between the free radicals of oxygen, nitrogen, and carbon. Also, the main metabolic pathways for these radical species are described, as well as how these affect their interaction and functional implications.

Reactive oxygen and nitrogen species: Friends or foes?
Biochemistry (Moscow), 2005Chemical and physiological functions of molecular oxygen and reactive oxygen species (ROS) and existing equilibrium between pools of pro-oxidants and anti-oxidants providing steady state ROS level vital for normal mitochondrial and cell functioning are reviewed.

[Reactive oxygen and nitrogen species].
Polski merkuriusz lekarski : organ Polskiego Towarzystwa Lekarskiego, 2012Reactive oxygen and nitrogen species (ROS and RNS respectively) play an important role in the proper functioning of many cellular processes. Generation of reactive oxygen species is an integral part of aerobic metabolism of cells. Their overproduction and subsequent oxidative stress occurs during pathogenesis of many diseases.

Ras Regulation by Reactive Oxygen and Nitrogen Species
Biochemistry, 2006Ras GTPases cycle between inactive GDP-bound and active GTP-bound states to modulate a diverse array of processes involved in cellular growth control. We have previously shown that both NO/O(2) (via nitrogen dioxide, (*)NO(2)) and superoxide radical anion (O(2)(*)(-)) promote Ras guanine nucleotide dissociation.

[Reactive nitrogen and oxygen species].
Polski merkuriusz lekarski : organ Polskiego Towarzystwa Lekarskiego, 2010Reactive nitrogen species (RNS) and reactive oxygen species (ROS) are mainly free radicals which including non-paired electrons. They are constantly formed as side products of biological reactions. They are also generated directly and indirectly by the cells which were exposed to environmental stress, i.e., UV radiation, ionizing radiation ...
