Effects of Different Concentrations of Melatonin on the Time-course of Nitrite–induced Oxidation of Hemoglobin: In vitro Study

Iraqi Journal of Pharmaceutical Sciences, 2017
Melatonin is a potent scavenger of reactive oxygen species or free radicals like superoxide and hydroxyl radicals. The oxidation of hemoglobin to methemoglobin (meth-Hb) by oxidizing compounds has been widely studied.

Dissimilatory Nitrite and Nitric Oxide Reductases [PDF]

Chemical Reviews, 1996
The inorganic nitrogen cycle (Figure 1) consists of several linked biological processes and one abiological process, the reaction of N2 and O2 in lightning discharges and internal combustion engines to produce NOx and, ultimately, nitrate. All of the processes except nitrogen fixation involve reduction or oxidation of species containing N-O bonds of ...

Meat processing and colon carcinogenesis: Cooked, nitrite-treated and oxidized high-heme cured meat promotes mucin depleted foci in rats [PDF]

, 2010
Processed meat intake is associated with colorectal cancer risk, but no experimental study supports the epidemiologic evidence. To study the effect of meat processing on carcinogenesis promotion, we first did a 14-day study with 16 models of cured meat ...

Fabrication of highly sensitive nitrite electrochemical sensor in foodstuff using nanostructure sensor

International Journal of Electrochemical Science, 2017
In this research, we introduced a powerful electrochemical sensor (based carbon paste electrode) for analysis of nitrite in foodstuff, using CdO decorated single wall carbon nanotube incorporated with 1-methyl-3-butylimidazolium bromide (CdO/SWCNTs/1-3 ...

Betanin inhibits the myeloperoxidase/nitrite-induced oxidation of human low-density lipoproteins [PDF]

, 2007
Production of nitrogen dioxide by the activity of myeloperoxidase (MPO) in the presence of nitrite is now considered a key step in the pathophysiology of low-density lipoprotein (LDL) oxidation.

Present and future pharmacotherapeutic agents in heart failure: an evolving paradigm [PDF]

, 2016
Many conditions culminate in heart failure (HF), a multi-organ systemic syndrome with an intrinsically poor prognosis. Pharmacotherapeutic agents that correct neurohormonal dysregulation and haemodynamic instability have occupied the forefront of ...

Nitrite influence on fish: a review

Veterinární Medicína, 2005
Nitrite is an intermediate in the oxidation of ammonium to nitrate. An elevated ambient nitrite concentration is a potential problem for freshwater fish since nitrite is actively taken up across the gills in competition with chloride.
