Microbial oxidation of arsenite in a subarctic environment: diversity of arsenite oxidase genes and identification of a psychrotolerant arsenite oxidiser [PDF]
, 2010 Background: Arsenic is toxic to most living cells. The two soluble inorganic forms of arsenic are arsenite (+3) and arsenate (+5), with arsenite the more toxic. Prokaryotic metabolism of arsenic has been reported in both thermal and moderate environments

Effect of hexane extract of spinach in the removal of arsenic from rat
Bangladesh Journal of Pharmacology, 2007 Extensive search is going on for a cheap, easily available and effective remedy of chronic arsenic poisoning. The present study was designed to find the effects of hexane extract of spinach in the removal of arsenic from arsenic treated rat.

BMC Pharmacology and Toxicology, 2021 Background Arsenic poisoning affects millions of people. The inorganic forms of arsenic are more toxic. Treatment for arsenic poisoning relies on chelation of extracellularly circulating arsenic molecules by 2,3-dimecaptosuccinic acid (DMSA).

Absence of arsenate in DNA from arsenate-grown GFAJ-1 cells [PDF]
, 2012 A strain of Halomonas bacteria, GFAJ-1, has been reported to be able to use arsenate as a nutrient when phosphate is limiting, and to specifically incorporate arsenic into its DNA in place of phosphorus. However, we have found that arsenate does not contribute to growth of GFAJ-1 when phosphate is limiting and that DNA purified from cells grown with ...

The Role of Reactive Oxygen Species in Arsenic Toxicity
Biomolecules, 2020 Arsenic poisoning is a global health problem. Chronic exposure to arsenic has been associated with the development of a wide range of diseases and health problems in humans. Arsenic exposure induces the generation of intracellular reactive oxygen species

Animal Models and Experimental Medicine, EarlyView.In an ethanol (EtOH)‐treated mouse model, increases in the NLRP3 inflammasome proteins, PC degeneration, and motor coordination disorders were observed. DIP suppressed the NLRP3‐ASC‐caspase‐1 signaling pathway, and alleviated the motor deficits and cerebellar pathological changes in chronic EtOH‐treated mice.

Mechanisms of arsenic clustering in silicon [PDF]
, 2005 A model of arsenic clustering in silicon is proposed and analyzed. The main feature of the proposed model is the assumption that negatively charged arsenic complexes play a dominant role in the clustering process. To confirm this assumption, electron density and concentration of impurity atoms incorporated into the clusters are calculated as functions ...
