Reactive nitrogen species in the chemical biology of inflammation

Archives of Biochemistry and Biophysics, 2004
The preponderance of epidemiological evidence now points to a strong association between chronic inflammation and cancers of several organs, including the gastrointestinal tract, liver, and lungs. The strongest evidence for a mechanistic link here involves the generation of reactive oxygen and nitrogen species by macrophages and neutrophils that ...

Chemiluminescence Measurement of Reactive Sulfur and Nitrogen Species

Antioxidants and Redox Signaling, 2022
Significance: Reactive sulfur and nitrogen species such as hydrogen sulfide (H 2 S) and nitric oxide (NO • ) are ubiquitous cellular signaling molecules that play central roles in physiology and ...

Aging and the Role of Reactive Nitrogen Species

Annals of the New York Academy of Sciences, 2002
AbstractThe role of reactive oxygen species and its effects on aging has received considerable attention in the past 47 years since Dr. Denham Harman first proposed the “free radical theory of aging.” Though not completely understood due to the incalculable number of pathways involved, the number of manuscripts that facilitate the understanding of the ...

Reactive nitrogen species in the respiratory tract

European Journal of Pharmacology, 2006
Endogenous 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 ...

Reactive Nitrogen Species in Colon Carcinogenesis

Antioxidants & Redox Signaling, 1999
The 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

Reactive Oxygen and Nitrogen Species

Nursing Research, 2015
Reactive 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 ...

THE REACTIVE SPECIES IN ACTIVE NITROGEN

Canadian Journal of Chemistry, 1962
A 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, 2022
Three 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 ...
