Abstract figure legend Both ATP synthase and adenine nucleotide translocator (ANT) play key roles in mediating the permeability transition. The contribution of ANT becomes evident in the presence of atractylate (ATR) at pH 6.5, a condition that prevents ATP synthase channel activity. At pH 7.4, this effect is minimal, suggesting a critical role for ATP

Both arsenic pollution and eutrophication are prominent environmental issues when considering the problem of global water pollution. It is important to reveal the effects of arsenic species on cyanobacterial growth and toxin yields to assess ecological ...

Neutralization of arsenic pollutants, contained in natural waters: The theoretical analysis of solubility of some arsenates and optimization of the processes [PDF]
Arsenic belongs to chemical elements, which are often found in natural waters and make it unsuitable for consumption without special treatment. Neutralization of arsenic pollutants of natural waters by converting them into insoluble form is one of the ...

The recent paper by Wolfe-Simon et al.1 reporting a bacterial strain, which is able to grow in high concentrations of arsenate, apparently in the absence of phosphate, and claims that in this strain arsenate is substituting for phosphate, e.g. in nucleic

Rethinking Arsenate Coordination at the Surface of Goethite
A fundamental precept of geochemistry is that arsenate coordinates at mineral surfaces in a predominately bridging-bidentate fashion. We show that this is incorrect for the model system, arsenate adsorbed at the surface of goethite (alpha-FeOOH), using a

MIn(HAsO4)2 (M = K, Rb, Cs): three new hydrogenarsenates adopting two different structure types
Potassium indium bis[hydrogen arsenate(V)], KIn(HAsO4)2, rubidium indium bis[hydrogen arsenate(V)], RbIn(HAsO4)2, and caesium indium bis[hydrogen arsenate(V)], CsIn(HAsO4)2, were grown under mild hydrothermal conditions (T = 493 K, 7–8 d).

Response to arsenate treatment in Schizosaccharomyces pombe and the role of its arsenate reductase activity. [PDF]
Arsenic toxicity has been studied for a long time due to its effects in humans. Although epidemiological studies have demonstrated multiple effects in human physiology, there are many open questions about the cellular targets and the mechanisms of ...
