Nitric oxide production by arsenite

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2003
Arsenic can either enhance or reduce nitric oxide (NO) production, depending on the type of cell, the species and dose of arsenical tested. The mechanisms of how arsenic increases or decreases NO production remain unclear. Because NO is associated with many pathological conditions, it is conceivable that in those arsenic-target tissues, the NO ...

Novel synergistic hydrous iron-nickel-manganese (HINM) trimetal oxide for hazardous arsenite removal.

Chemosphere, 2018
A novel hydrous iron-nickel-manganese (HINM) trimetal oxide was successfully fabricated using oxidation and coprecipitation method for metalloid arsenite removal. The atomic ratio of Fe:Ni:Mn for this adsorbent is 3:2:1.

Diversity of inorganic arsenite biotransformation

Biological Trace Element Research, 1999
Biotransformation of inorganic arsenic in mammals is catalyzed by three serial enzyme activities: arsenate reductase, arsenite methyltransferase, and monomethylarsonate methyltransferase. Our laboratory has purified and characterized these enzymes in order to understand the mechanisms and elucidate the variations of the responses to arsenate/arsenite ...

The inhibition of acetylcholinesterase by arsenite and fluoride

Archives of Biochemistry and Biophysics, 1983
The effect of fluoride on the rate of reaction of acetylcholinesterase with arsenite, on the rate of dissociation of the enzyme-arsenite complex, and on the equilibrium between enzyme and arsenite was studied. Fluoride decreases the rate of the reaction between acetylcholinesterase and arsenite and changes the apparent equilibrium dissociation constant

Mass Poisoning By Sodium Arsenite

Journal of Toxicology: Clinical Toxicology, 1991
An acute massive epidemic of arsenic poisoning in Argentina involved 718 subjects. Urine samples were obtained from 307. The 49 with urine arsenic 76-500 micrograms/dl and 12 with urine arsenic greater than 500 micrograms/dL received dimercaprol treatment.

Arsenite and arsenate levels in wine

Bulletin of Environmental Contamination and Toxicology, 1977
Arsenic is receiving renewed attention because it is released to the atmosphere by coal-fired power plants as well as by smelters and agricultural pesticides. A portion of this arsenic that accumulates on agricultural land may be taken up by plants, animals, and ultimately by man.
