The effects of administration of nonselective inhibitor of NO-synthase under X-ray radiation

open access: yesБіологічні студії, 2009
Total activity of NO-synthetase and content of nitrates and nitrites in immu­no­competent cells of rat peripheral blood under the influence of fraction x-ray radiation and peroral administration of L-NAME were studied. It was shown that administration of

Conversion of nitrite of nitrate by nitrite-resistant yeasts.

open access: yesAgricultural and Biological Chemistry, 1988
Candida species YK 11 and YK 92 and Geotrichum candidum YK 57, which were isolated as nitrite-resistants, converted nitrite in the culture medium to nitrate stoichiometrically during growth. The nitrite-oxidizing reaction was confirmed under aerobic conditions in the intact cell system with 15mM nitrite, 150mM glucose, and 100mM Tris-HCl buffer (pH 7.0)

Nitrate Reduction to Nitrite, a Possible Source of Nitrite for Growth of Nitrite-Oxidizing Bacteria [PDF]

open access: yesApplied and Environmental Microbiology, 1977
Growth yields and other parameters characterizing the kinetics of growth of nitrite-oxidizing bacteria are presented. These parameters were measured during laboratory enrichments of soil samples with added nitrite. They were then used to reanalyze data for nitrite oxidizer growth in a previously reported field study (M. G. Volz, L.

Researches on Nitrates and Nitrites Content in Raw Milk [PDF]

open access: yes, 2011
Nitrates and nitrites from milk may have different origins. The water polluted with nitrates and nitrites can get into milk especially during the cleaning operations of equipment and vessels. The main source of water contamination is the ammonium nitrate

Prooxidative-Antioxidant Regulation in Patients with Serous Meningitis

open access: yesAktualʹnaâ Infektologiâ, 2016
Introduction. Serous meningitis takes a leading place among the central nervous system lesions, the share of which in neuroinfections structure ranges from 25 to 70 %. The imbalance in the functioning of prooxidant-antioxidant system plays a leading role

Efficient Microwave-Assisted Extraction of Nitrites from Cured Meat and Their Voltammetric Detection at Chemically Modified Electrodes Based on Hexamethyl-p-Terphenyl Poly(methylatedbenzimidazolium) Incorporating Nitrogen-Doped Graphite Nanoplatelets

open access: yesChemosensors, 2021
We describe a fast and reliable procedure for the efficient extraction of nitrites in cured meat using microwave-assisted heat and report their in situ determination via voltammetry using an anion-exchanger ionene, hexamethyl-p-terphenyl poly ...
