The gaseous signal molecule, nitric oxide (NO()), is generated enzymatically by NO synthase (NOS) from L-arginine. Overproduction of NO contributes to cell and tissue damage as Cited by: Nitric oxide (NO) is an important regulator of a variety of biological functions, and also has a role in the pathogenesis of cellular injury.

It had been generally accepted that NO is solely generated in biological tissues by specific nitric oxide synthases (NOS) which metabolize arginine to Cited by: Nitric Oxide Soil Organic Matter Calcareous Soil Nitrous Oxide Emission Nitrification Inhibitor These keywords were added by machine and not by the authors.

This process is experimental and the keywords may be updated as the learning algorithm improves. Except for the formation of nitric oxide, nitrite is reduced by the extracts to the same gaseous products formed by intact bacteria.

The pseudomo- nads reduce nitrite quantitatively to nitrogen under ordinary conditions (4, lo), while members of the B. subtilis group form an appreciable amount of NzO (11). Nat Med. Nov;1(11) Enzymatic/non-enzymatic formation of nitric oxide. Meyer DJ. Comment on Nat Med. Aug;1(8)Cited by: –).The non-enzymatic reaction of NO with oxygen in tissues is relatively slow, whereas its oxidation by the multicopper oxidase ceruloplasmin in plasma is rapid.

Commensal bacteria in the oral cavity and gastrointestinal tract contribute to nitrite formation via a one-electron reduction of nitrate. As expression of the inducible nitric oxide synthase (iNOS) is a normal response of human skin to UV radiation we examined the role of nitric oxide (NO) as a protective agent during or even after.

Since its initial discovery as an endogenously produced bioactive mediator, nitric oxide (• NO) has been found to play a critical role in the cellular function of nearly all organ rmore, aberrant production of • NO or reactive nitrogen species (RNS) derived from • NO, has been implicated in a number of pathological conditions, such as acute lung disease, atherosclerosis and Cited by: A non-protein amino acid, citrulline, is a compatible solute involved in the maintenance of cellular osmolarity during abiotic stresses.

Despite its significance, a coherent model indicating the. Zweier JL, Samouilov A, Kuppusamy P. Non-enzymatic nitric oxide synthesis in biological systems.

Nitric oxide production from nitrite occurs primarily in tissues not in the blood: critical role of xanthine oxidase and aldehyde oxidase.

Nitric oxide (NO) is a reactive free radical with pleiotropic functions that participates in diverse biological processes in plants, such as germination, root development, stomatal closing, abiotic stress, and defense responses.

It acts mainly through Cited by: Arsenic poisoning is a medical condition that occurs due to elevated levels of arsenic in the body. If arsenic poisoning occurs over a brief period of time symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood.

Long-term exposure can result in thickening of the skin, darker skin, abdominal pain, diarrhea, heart disease, numbness, and : Arsenic. Contamination of air, soil, and water resources with potentially toxic elements (PTEs) is a global environmental issue [1,2].Most of the PTEs are toxic to plants and animals including humans [3,4,5].Among the PTEs, arsenic (As) is considered as one of the most highly toxic and carcinogenic [6,7,8,9].The US Environmental Protection Agency (EPA) and the International Agency for Research Cited by:   Protein S-Nitrosylation in Seeds.

Nitric oxide-mediated S-nitrosylation of cysteine thiol groups within polypeptide chains is a likely mechanism by which NO may function in signaling processes (Stamler et al., a; Jaffrey et al., ).

S-nitrosylation consists in the covalent attachment of a NO moiety to a reactive cysteine thiol resulting in the formation of a S-nitrosothiol group (S-NO).Cited by: Clay minerals, lipids and, more recently, peptides were found to catalyze the non-enzymatic synthesis of RNA oligomers.

Herein, a review of the main models for the formation of the first RNA polymers is presented in such a way as to emphasize the cooperation between life’s building blocks in their emergence and evolution.

Hydrogen peroxide (H2O2), as a reactive oxygen species, is widely generated in many biological systems. It has been considered as an important signaling molecule that mediates various physiological and biochemical processes in plants.

Normal metabolism in plant cells results in H2O2 generation, from a variety of sources. Also, it is now clear that nitric oxide (NO) and calcium (Ca2+) function Cited by: nitric oxide-cyclic GMP pathway in the rat in vivo. Neurochem Int 34(3) *Hewitt CD, Innes DJ, Herman MM, et al.

The site also contains the forms to search the most useful sites on the Web.The root to soil respiration ratio increased rapidly during the young seedling stage, i.e.

first five months, then declined and finally got stabilized during yield formation and ripening stages, respectively. In addition, the results from the measurements confirmed that soil respiration was positively correlated with soil moisture content.
