Background: In the present study, histopathological effects of chronic exposure to sodium arsenate in drinkable water were studied on a quantity of organs of rat. Methods: Rats were divided into two groups, group I served as control group, were main-tained on deionized drinkable water for 2 months, and group II the study group were given 60 g/ml of sodium arsenate in deionized drinkable wa...

Rice (Oryza sativa) varieties that are arsenate-tolerant (Bala) and -sensitive (Azucena) were used to conduct a transcriptome analysis of the response of rice seedlings to sodium arsenate (AsV) in hydroponic solution. RNA extracted from the roots of three replicate experiments of plants grown for 1 week in phosphate-free nutrient with or without 13.3 muM AsV was used to challenge the Affymetrix...

This study examined the roles of arsenic translocation and reduction, and P distribution in arsenic detoxification of Pteris vittata L. (Chinese Brake fern), an arsenic hyperaccumulator and Pteris ensiformis L. (Slender Brake fern), a non-arsenic hyperaccumulator. After growing in 20% Hoagland solution containing 0, 133 or 267 microM of sodium arsenate for 1, 5 or 10 d, the plants were separate...

ARSENIC poisoning in livestock may be caused by arsenic trioxide (white arsenic), paris green, sodium arsenite, and sodium arsenate. Arsenic has been a common cause of accidental and criminal poisoning of animals because it often is used to kill insects, parasites, weeds, and rodents and as a tonic for animals. Arsenic compounds usually are palatable to animals, especially when they are hungry ...

Background &Objectives: Cardiovascular diseases and hypertension has a significant correlation with chronic arsenic exposure through drinking water. This study was designed to investigate the prevention of sodium arsenate induced vascular disorders by Vitamins C& E in fetal renal blood vessels albino mice.
 Materials & Methods: Gravid mice BALB/c strain (twenty four) were rando...

Potassium sodium silver tetra-niobium nona-oxide arsenate, K(0.12)Na(0.54)Ag(0.34)Nb(4)AsO(13), synthesized by solid-state reaction at 1123 K, adopts a three-dimensional framework delimiting tunnels running along [001] in which occupationally disordered sodium, silver, and potassium ions are located. Of the 11 atoms in the asymmetric unit (two Nb, one As, one Ag, one K, one Na and fiveO), nine ...

The title compound, sodium dioxidomolybdenum(VI) arsenate(V), β-NaMoO(2)AsO(4), was prepared by solid-state reaction at 953 K. In the crystal structure, the AsO(4) tetra-hedra and MoO(6) octa-hedra (both with m symmetry) share corner atoms to form a three-dimensional framework that delimits cavities parallel to [010] where disordered six-coordinated sodium cations (half-occupation) are located....

A mutant designated as pvcys exhibiting huge deficiency in foliar L-cysteine desulfhydrase and D-cysteine desulfhydrase activity were isolated from an ethylmethane sulfonate-mutagenized M2 population of a Phaseolus vulgaris L. genotype VL 63. The mutant showed growth inhibition and morpho-agronomic anomalies but exhibited high cysteine content and very low endogenous hydrogen sulfide concentrat...

This study investigated the effects of arsenic on the in vitro activities of the enzymes (nitrate reductase and nitrite reductase) involved in nitrate metabolism in the roots, rhizomes, and fronds of four-month old Pteris vittata (arsenic - hyperaccumulator) and Pteris ensiformis (non-arsenic-hyperaccumulator) plants. The arsenic treatments (0, 150, and 300 microM as sodium arsenate) in hydropo...
