Disease relevance of vanadium

• Aqueous chemistry of the vanadium(III) (V(III)) and the V(III)-dipicolinate systems and a comparison of the effect of three oxidation states of vanadium compounds on diabetic hyperglycemia in rats [1].
• Vanadium(III) complexes with L-cysteine--stability, speciation and the effect on actin in hepatoma Morris 5123 cells [2].

High impact information on vanadium

• Examination of the properties of this extremely low field signal revealed that it corresponds to a labile vanadium (III) aquo complex contained in the cell vacuoles, that vanadium(III) concentrations are rigidly regulated within these vacuoles, and that artifact formation does occur in the hemolysate [3].
• Thus, in contrast to A. ceratodes, a significant fraction of the blood cell vanadium(III) in A. nigra is apparently in a ligation environment substantially different from that provided by water [4].
• Aerial oxidation/hydrolysis of the vanadium(III) species gives their oxovanadium(IV) analogues of the general formula [V(IV)O(dip)(phen)] [5].
• Oxidation of vanadium(III) by hydrogen peroxide and the oxomonoperoxo vanadium(V) ion in acidic aqueous solutions: a kinetics and simulation study [6].
• Structure and bonding of the vanadium(III) hexa-aqua cation. 2. Manifestation of dynamical Jahn-Teller coupling in axially distorted vanadium(III) complexes [7].

Biological context of vanadium

• The first example of a seven-coordinate vanadium(III) thiolate complex containing the hydrazine molecule, an intermediate of nitrogen fixation [8].
• Cytochemical localization of vanadium(III) in blood cells of ascidian Phallusia mammillata Cuvier, and its relevance to hematic cell lineage determination [9].
• A hypothesis correlating ascidian blood cell function to anaerobiosis, via two prominent redox constituents, namely vanadium(III) and the tunichromes, a family of metal ion complexing/reducing hydroquinonoid peptides, is presented [10].

Anatomical context of vanadium

• It is also possible that accumulated vanadium(III) is sequestered in hydrophobic regions of the vacuolar or cellular membranes [11].

Associations of vanadium with other chemical compounds

• The complexation processes of vanadium(III) with L-cysteinate and s-methyl-L-cysteinate ligands have been studied in aqueous solutions in the pH range 2-7 by the pH-potentiometric, UV-Vis absorption and CD spectroscopy methods [2].

Gene context of vanadium

• Structure and bonding of the vanadium(III) hexa-aqua cation. 1. Experimental characterization and ligand-field analysis [12].
• The preparation procedure of vanadium(III) transferrin and its stability are confirmed to be as previously reported [13].

Analytical, diagnostic and therapeutic context of vanadium

• Investigation into the nature of the species arising in those solutions revealed, through UV/visible and EPR spectroscopies, oxidation of vanadium(III) to vanadium(IV) [14].
