In this paper, we proposed a procedure for the determination of iron(II) and total iron in wine samples employing molecular absorption spectrophotometry. The ligand used is 2-(5-bromo-2-pyridylazo)-5-(diethylamino)-phenol ...

BackgroundNitric oxide (NO) is a signalling and physiologically active molecule in animals, plants and bacteria. The specificity of the molecular mechanism(s) involved in transducing the NO signal within and between cells ...

Avicennia schaueriana, Laguncularia racemosa and Rhizophora mangle were experimentally exposed to increasing levels of iron (0, 10, 20 and 100 mg L-1 added Fe(II) in Hoagland's nutritive medium). The uptake and translocation ...

A highly sensitive extraction-spectrophotometric method has been developed for the determination of iron based on the formation of a ternary complex with 1,10-phenanthroline as a primary ligand and picrate as a counter ...

The aim of this study was to characterize nonheme iron (NHI) and heme iron (HI) microparticles to elaborate a novel oral iron supplement, determining its effect on the iron nutritional status of neonatal piglets. Nonheme ...

Fe is an essential micronutrient for Brucella strains. Meeting their physiologic need for this metal is especially challenging for these bacteria because they live in close association with their mammalian hosts, and ...
