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.

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 ...

Characterization of reactive nitrogen species in allergic asthma
Annals of Allergy, Asthma & Immunology, 2014To investigate the molecular mechanism of reactive nitrogen species (RNS) in the pathogenesis of asthma and examine the use of fractional exhaled nitric oxide (FENO) measurements in close conjunction with standard clinical assessments of asthma.Through PubMed, Google Scholar, and Medline databases, a broad medical literature review was performed in the

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.

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.

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 ...

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 Oxygen and Nitrogen Species
2004The term “radical” is often used loosely in chemistry to refer to various groups of atoms that behave as a unit, such as the carbonate radical (CO 3 sup2- ), nitrate radical (NO 3 sup- ), and the methyl radical (CH3p-). According to this definition, Lavoisier (1789) has already indicated that the four elements: phosphorus, sulphur, carbon, and hydrogen

Pindolol is a potent scavenger of reactive nitrogen species
Life Sciences, 2005Pindolol is an indolic drug that has been shown to enhance and/or accelerate selective serotonin specific reuptake inhibitors (SSRI)-induced antidepressant (AD) effect, even though the respective mechanism is still unclear. It has been demonstrated that inhibition of nitric oxide (*NO) synthesis in CNS produces anxiolytic and AD-like behavioural ...
