Abiotic formation of elemental selenium and role of iron oxide surfaces.

Yu-Wei Chen et al.

Chemosphere, 74(8), 1079-1084 (2008-12-09)

The possible abiotic reduction of selenite to form elemental Se was studied under controlled conditions in the presence of ferrous iron. The reduction of selenite and formation of Se (0) was found to be a surface-mediated reaction by iron oxides.

Differential patterns of accumulation and depuration of dietary selenium and vanadium during metamorphosis in the Gray Treefrog (Hyla versicolor).

Christopher L Rowe et al.

Archives of environmental contamination and toxicology, 60(2), 336-342 (2010-09-30)

Selenium (Se) and vanadium (V) are contaminants commonly found in aquatic systems affected by wastes derived from fossil fuels. To examine their effects on a widely distributed species of amphibian, we exposed gray tree frogs (Hyla versicolor) to Se (as

Selenite resistant rhizobacteria stimulate SeO(3) (2-) phytoextraction by Brassica juncea in bioaugmented water-filtering artificial beds.

Silvia Lampis et al.

Environmental science and pollution research international, 16(6), 663-670 (2008-12-24)

Selenium is a trace metalloid of global environmental concern. The boundary among its essentiality, deficiency, and toxicity is narrow and mainly depends on the chemical forms and concentrations in which this element occurs. Different plant species-including Brassica juncea-have been shown

CD95 promotes metastatic spread via Sck in pancreatic ductal adenocarcinoma.

M Teodorczyk et al.

Cell death and differentiation, 22(7), 1192-1202 (2015-01-24)

Cancer stem cells (CSCs) have been implicated in the initiation and maintenance of tumour growth as well as metastasis. Recent reports link stemness to epithelial-mesenchymal transition (EMT) in cancer. However, there is still little knowledge about the molecular markers of
