Hydrogen and sulfur from hydrogen sulfide—V. Anodic oxidation of sulfur on activated glassy carbon
Fast, ambient-temperature, steady electrolysis of H2S from solutions of NaSH in aqueous NaOH was achieved using suitably activated glassy carbon anodes. Thus electrolyses of H2S can probably be carried out at high rates with modest cell voltages in the range 1−1.5 V. The variation in anode current densities with [NaSH], [NaOH], and anode rotational speed is presented.
Background ::: Unsaturated fatty acids (FA) are required for cancer cell growth. In normoxia cells can generate unsaturated FA from saturated stearic and palmitic acid by desaturation. However, since the desaturation step is oxygen-dependent hypoxic cancer cells display an increased dependence on the uptake of unsaturated FA. Up to now the mechanism of increased FA uptake in hypoxia is largely unknown. Here we aimed to study the role of human serum and glucocorticoid-inducible kinase (SGK1) in the regulation of FA uptake in cancer cells exposed to acute or chronic cycling hypoxia and explore its use as target for the radiosensitization of hypoxic cancer cells.
