Sentence examples for more efficient arsenic from inspiring English sources

This haplotype was associated with low %MMA and high %DMA, consistent with more efficient arsenic metabolism (Engström et al. 2011).

Likewise, a haplotype that has not been associated with more efficient arsenic metabolism appeared in only 26% of the SAC population, compared with 67% of HGDP individuals and 40% of Peruvians.

This suggests the hypothesis that genetic selection for AS3MT haplotypes associated with a more efficient arsenic metabolism has occurred in populations that have lived in areas with elevated arsenic exposure for thousands of years.

Hopenhayn-Rich et al. (1996) reported more efficient arsenic methylation in persons of Atacameño ethnicity (12.6% MMA in urine), compared with those of European ancestry on the Chilean side of the Andes highlands (17.2%, p < 0.001 between groups).

Some populations in the Andes, including the Atacameño people living in San Antonio de los Cobros (SAC), Argentina, carry a particular variant (haplotype) of the arsenic-metabolizing gene AS3MT that is associated with more efficient arsenic metabolism and perhaps lower health risks from exposure.

The findings from this study raise the possibility that haplotypes in AS3MT, associated with a more efficient arsenic metabolism and a probably lower formation of the most toxic metabolite, may have undergone positive selection in populations who have lived for a very long time in areas with high arsenic concentrations in the drinking water.

The results suggest that carriage of AS3MT haplotypes associated with less-efficient arsenic methylation, or lack of AS3MT haplotypes associated with a more-efficient arsenic methylation, results in higher risk of arsenic-related BCC.

Such a process could potentially be useful for a more efficient remediation of arsenic in environments where birnessite can absorb photons having a requisite energy.

Because previous work from more highly exposed individuals has indicated that higher PMI may be associated with greater health risks (Chen et al. 2013), one might expect to see stronger effects only in those with high PMI, which could indicate inefficient arsenic metabolism, as opposed to high SMI, which may indicate more efficient methylation and therefore arsenic excretion.

Since induction of heme oxygenase is a general response to oxidative stress, we suspect that the differential toxicity of arsenic to human and animal cells could be due to arsenic's more efficient induction of oxidative damage in human cells.

Arsenic removal is more efficient when arsenite is oxidized to arsenate by addition of hypochlorite at a concentration typically used for disinfection (1 mg L 1).
