Low serum total nitrite and nitrate levels in severe leptospirosis
BACKGROUND The relationship between inducible nitric oxide synthatase activity and disease severity in leptospirosis is unclear. Nitric oxide is converted to nitrites and nitrates, thus nitrite and nitrate levels (NOx) in serum are considered surrogate markers for nitric oxide. NOx are excreted through the kidneys, and elimination is diminished in renal impairment. We assessed the correlation o...
متن کاملThe Evaluation of Serum Nitrite, Nitrate and Malonyldialdehyde Levels in Smokers
Abstract Background and objectives: Smokers are exposed to significant quantities of ROS (Reactive Oxygen Species) and The Level of Nitric Oxide (NO), the primary vasodilator produced by endothelial cells, is changed by cigarette smoking. Cigarette smoking is associated with impaired endothelium-dependent vasodilatation and cardiovascular disease (CVD). The aim of this study is to determine the...
متن کاملNitrate and Nitrite Ultraviolet Actinometers
We developed nitrate and nitrite actinometers to determine radiant fluxes from 290 to 410 nm. These actinometers are based on the reaction of the photochemically generated OH radical with benzoic acid to form salicylic acid (SA) and p-hydroxybenzoic acid (pHBA). Actinometer development included determination of the temperature and wavelength dependence of the quantum yield for formation of SA a...
متن کاملL-Arginine Supplementation Influenced Nitrite but Not Nitrate and Total Nitrite in Rabbit Model of Hypercholesterolemia
Background: The assessment of altered nitric oxide (NO) availability is of potentially important diagnostic and prognostic significance. The present study is aimed to investigate the effect of L-arginine (as a natural NO donor) supplementation on NO metabolite in a rabbit model of hypercholesterolemia to find a reliable marker for endothelial NO production. Methods: White male rabbits (n = 30)...
متن کاملThe P aracoccus denitrificans NarK‐like nitrate and nitrite transporters—probing nitrate uptake and nitrate/nitrite exchange mechanisms
Nitrate and nitrite transport across biological membranes is often facilitated by protein transporters that are members of the major facilitator superfamily. Paracoccus denitrificans contains an unusual arrangement whereby two of these transporters, NarK1 and NarK2, are fused into a single protein, NarK, which delivers nitrate to the respiratory nitrate reductase and transfers the product, nitr...
