Electrochemistry and spectroelectrochemistry of iron porphyrins in the presence of nitrite [PDF]

, 2001
The reaction of nitrite with ferric and ferrous porphyrins was examined using visible, infrared and NMR spectroscopy. Solutions of either ferric or ferrous porphyrin were stable in the presence of nitrite, with only complexation reactions being observed.

Effects of acute consumption of fruit and vegetable puree-based drinks on vasodilation and oxidative status [PDF]

, 2012
Epidemiological studies indicate that diets rich in fruits and vegetables (F&V) are protective against cardiovascular diseases (CVD). Pureed \&V products retain many beneficial components, including flavonoids, carotenoids, vitamin C and dietary fibres ...

Oxidation of Native and Modified Hemoglobin and Myoglobin by Sodium Nitrate. Effect of Inositol Hexaphosphate [PDF]

, 1981
Native and modified hemoglobin, myoglobin and a and phemoglobin subunits were oxidized by sodium nitrite at pH 6. The experiments were carried out under oxy and deoxy conditions with and without inositol hexaphosphate (IHP).

Environmentally friendly synthesis of CeO2 nanoparticles for the catalytic oxidation of benzyl alcohol to benzaldehyde and selective detection of nitrite

Scientific Reports, 2017
Cerium oxide nanoparticles (CeO2 NPs) are favorable in nanotechnology based on some remarkable properties. In this study, the crystalline CeO2 NPs are successfully prepared by an efficient microwave combustion (MCM) and conventional route sol-gel (CRSGM)

The relationship between redox enzyme activity and electrochemical potential—cellular and mechanistic implications from protein film electrochemistry [PDF]

, 2011
In protein film electrochemistry a redox protein of interest is studied as an electroactive film adsorbed on an electrode surface. For redox enzymes this configuration allows quantification of the relationship between catalytic activity and ...

The key role of nitric oxide in hypoxia: hypoxic vasodilation and energy supply-demand matching [PDF]

, 2013
Significance: a mismatch between energy supply and demand induces tissue hypoxia with the potential to cause cell death and organ failure. Whenever arterial oxygen concentration is reduced, increases in blood flow - 'hypoxic vasodilation' - occur in an ...

Reduced nitrite accumulation at the primary nitrite maximum in the cyclonic eddies in the western North Pacific subtropical gyre

Science Advances, 2023
Nitrite, an intermediate product of the oxidation of ammonia to nitrate (nitrification), accumulates in upper oceans, forming the primary nitrite maximum (PNM). Nitrite concentrations in the PNM are relatively low in the western North Pacific subtropical

The usage of nitrogen compounds by purple non-sulfur bacteria of the Rhodopseudomonas genus

Regulatory Mechanisms in Biosystems, 2019
In this article, we characterized the regularities of oxidation of nitrite ions by phototropic purple non-sulfur bacteria Rhodopseudomonas yavorovii IMV B-7620, which were isolated from the water of Yavorivske Lake (Lviv Region, Ukraine).

Nitro-fatty acid formation and metabolism [PDF]

, 2018
Nitro-fatty acids (NO 2 -FA) are pleiotropic modulators of redox signaling pathways. Their effects on inflammatory signaling have been studied in great detail in cell, animal and clinical models primarily using exogenously administered nitro-oleic acid ...
