[Reactive nitrogen and oxygen species].
Polski merkuriusz lekarski : organ Polskiego Towarzystwa Lekarskiego, 2010Reactive nitrogen species (RNS) and reactive oxygen species (ROS) are mainly free radicals which including non-paired electrons. They are constantly formed as side products of biological reactions. They are also generated directly and indirectly by the cells which were exposed to environmental stress, i.e., UV radiation, ionizing radiation ...

Nitric Oxide and Reactive Nitrogen Species
2014Nitric oxide (NO) plays a key role in plant metabolism, signaling, defense, and development. However, a fundamental question arises how the NO message is converted into a physiological response. NO-related signaling may be attributed to various NO derivatives, collectively named reactive nitrogen species (RNS).

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 ...

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
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

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.

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

Regulation of ryanodine receptors by reactive nitrogen species
Biochemical Pharmacology, 1999The ryanodine receptors (RyRs) are large intracellular calcium release channels that play an important role in the control of the calcium levels in excitable and non-excitable cells. Many endogenous modulators such as Mg2+, ATP, or calmodulin can affect the channel activities of the three known mammalian RyR isoforms.
