We describe a real-time PCR assay for the quantitative detection of arsB and ACR3(1) arsenite transporter gene families, two ubiquitous and key determinants of arsenic resistance in prokaryotes. The assay was applied in batch growth experiments using a wasteland soil bacterial community as an inoculum to investigate the effect of increasing arsenite ...

Inorganic arsenic (iAs), a ubiquitous element and a natural drinking water contaminant, has been found to impair male reproductive function. However, the effect of long-term exposure to arsenic on testis damage and its underlying mechanisms still require

The metabolism of arsenite and arsenate by the rat
Fundamental and Applied Toxicology, 1983Differences in distribution and metabolism of arsenite and arsenate were studied in rats and in rat liver and kidney slices and hepatocytes. Five minutes after i.v. administration of 4.8 nmol arsenite or arsenate to male Sprague-Dawley rats, blood levels of arsenic were only 10 percent of the initial dose.

Application of iron-modified biochar for arsenite removal and toxicity reduction
, 2019In the present study, the Miscanthus biochar was modified with amorphous iron (hydr)oxide to remove arsenite. The kinetic study indicated the chemical adsorption of arsenite on the iron-modified biochar.

Arsenic (As) is a ubiquitous environmental toxin and robust inducer of oxidative stress (OxS). Copper (Cu) is an essential microelement, which participates in OxS as a cofactor for certain enzymes, with narrow optimal range between essential and toxic ...

A plasmid-encoded arsenite pump produces arsenite resistance in Escherichia coli
Biochemical and Biophysical Research Communications, 1984The arsenate resistance operon of R-factor R773, a conjugative resistance plasmid, has two functional regions, a promoter-proximal region encoding resistance to arsenite and antimonate, and a promoter-distal one encoding arsenate resistance. Cells bearing arsenite resistance plasmids exhibited reduced accumulation of 74AsO2-.
