A single and rapid solid surface fluorescence-based flow-through optosensor has been developed for the screening of trace amounts of Zn(II) in drinking water samples. The proposed method is based on the transient immobilization of the target species: the complex formed between Zn(II) and the fluorogenic reagent p-(tosylamino)quinoline (p-TAQ) on an appropriate solid support (C(18) silica gel). ...

Yeast alcohol dehydrogenase is a tetrameric enzyme containing zinc. Initially we confirmed the presence of two zinc atoms per subunit. Incubation of the enzyme with increasing concentrations of dithiothreitol, a method for partial chelation, allowed first the reduction of four disulphide bridges per enzyme, but eventually was sufficient to chelate the structural zinc atom without having any eff...

Ferrous metallurgy enterprises continuously fill dumps with steelmaking and blast furnace sludge high zinc content. Sludge occupying significant territories of is not involved in production harms the environment. Since leads to formation deposits furnace, manufacturers cannot involve this sinter processing. In addition, working can lead problems such as decrease iron content sinter, productivit...

The ability of metallothionein (MT) to modulate DNA binding by a two-finger peptide of Tramtrack (TTK), a CCHH zinc transcription factor, was investigated using metal-bound and metal-deficient forms of rabbit MT-2 and the TTK peptide. Thionein inhibited DNA binding by zinc-bound TTK, and Zn-MT restored DNA-binding by zinc-deficient apo-TTK. "Free" zinc at low concentrations was as effective as ...

Addressing malnutrition is among the many challenges in the effective control of tuberculosis. The nutritional status of micronutrients is poorly standardized. Zinc being one of the most vital micronutrients, it is taken up for study. This study is to analyze the status of Zinc in the serum of pulmonary tuberculosis patients. The levels of serum Zinc is measured and documented in freshly diagno...
