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 ...

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

Chemiluminescence Measurement of Reactive Sulfur and Nitrogen Species

Antioxidants & Redox Signaling, 2022
Significance: 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, 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 ...

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 ...
