Reactive Oxygen Species and Reactive Nitrogen Species in Epigenetic Modifications

, 2014
For 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.

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 ...

Interaction of lidocaine with reactive oxygen and nitrogen species

European Journal of Anaesthesiology, 2001
To investigate the ability of lidocaine to inhibit reactive oxygen and/or nitrogen species generation by either human leukocytes or cell-free systems via luminol- and lucigenin-enhanced chemiluminescence.Venous blood was obtained from healthy volunteers and leukocytes were isolated, from which chemiluminescence was generated.

Metal-Coordinated Fluorescent and Luminescent Probes for Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS)

Coordination Chemistry Reviews, 2021
Reactive oxygen species (ROS) are chemically reactive species containing oxygen, which are produced from molecular oxygen (O2) during vital processes occurring in humans and other living organisms.

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 ...
