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 ...

Reactive Nitrogen Species in Colon Carcinogenesis
Antioxidants & Redox Signaling, 1999The role of reactive nitrogen species (RNS) in colon carcinogenesis is multifactorial and affects diverse processes, such as proliferation, apoptosis, differentiation, tumorigenesis, and metastases. This review describes the stages in colon carcinogenesis where nitric oxide (NO) and inducible NO synthase (NOS2) may influence the progression of a normal

Chemiluminescence Measurement of Reactive Sulfur and Nitrogen Species
Antioxidants & Redox Signaling, 2022Significance: Reactive sulfur and nitrogen species such as hydrogen sulfide (H2S) and nitric oxide (NO•) are ubiquitous cellular signaling molecules that play central roles in physiology and pathophysiology. A deeper understanding of these signaling pathways will offer new opportunities for therapeutic treatments and disease management. Recent Advances:

Reactive Oxygen and Nitrogen Species
Nursing Research, 2015Reactive oxygen and nitrogen species, known as free radicals, play a key role in the etiology and progression of atherosclerotic cardiovascular disease by creating vascular oxidative stress.This review will discuss current biological research about the enzymatic and nonenzymatic sources of oxidative stress, free radical chemistry, and how it pertains ...

Reactive nitrogen species in the respiratory tract
European Journal of Pharmacology, 2006Endogenous Nitric Oxide (NO) plays a key role in the physiological regulation of airway functions. In response to various stimuli activated inflammatory cells (e.g., eosinophils and neutrophils) generate oxidants ("oxidative stress") which in conjunction with exaggerated enzymatic release of NO and augmented NO metabolites produce the formation of ...

Interactions between nitric oxide, oxygen, reactive oxygen species and reactive nitrogen species
Biochemical Society Transactions, 2006ROS (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

Reactive Oxygen Species and Reactive Nitrogen Species in Epigenetic Modifications
2014For the normal homeostasis of a cell, there must be a balance between radical oxygen species/radical nitrogen species (ROS/RNS) production and the neutralization of these species by antioxidant scavenging. In times of stress, this balance is not maintained, and the result is oxidative stress.

Electrochemical generation of reactive nitrogen species
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1990Abstract The anodic behavior of N,N-dialkylanilines having various kinds of electron-withdrawing groups at their α-positions was studied comparatively in methanol. These anilines underwent α-methoxylation and/or cleavage of a carbon-nitrogen bond depending on the kind of N-alkyl and electron-withdrawing groups.

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 ...

[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.
