The activity of glyoxalase I from the soluble fraction of diabetic rat liver was found to decrease as compared to the control. Sodium orthovanadate in drinking water and Trigonella foenum graecum seed powder when administered to these diabetic animals were found to reverse the activity of glyoxalase I to control values. A combination of the above two antidiabetic compounds showed a better rever...

Silver vanadate glasses show electrical conductivity higher than 10 S cm, caused by the electron hopping from V to V together with an ionic conduction due to Ag. Lithium vanadate glasses show electrical conductivity of the order of 10 S cm which is primarily due to an electron hopping from V to V. Fraction of the Ag or Li conduction and that of electron hopping from V to V can be estimated by m...

Friend murine erythroleukemia cells underwent apparently normal erythropoiesis when treated with dimethyl sulfoxide. One of the earliest events associated with this induction was a decrease in ouabain sensitive 86Rb+ uptake, an assay of the plasma membrane Na,K(ATPase). Ammonium vanadate (10 microM) blocked differentiation of these cells without affecting cell viability. Vanadium was taken up b...

Vanadium oxides are highly valued as electrochromic materials because of their multicolor capabilities. However, practical applications have been limited due to challenges such the dissolution vanadate into aqueous electrolytes, leading poor long-term stability. Herein, a solution is proposed issue by utilizing hybrid electrolyte consisting tetraethylene glycol dimethyl ether (TEGDME) and water...

The hairpin ribozyme catalyzes sequence-specific cleavage of RNA through transesterification of the scissile phosphate. Vanadate has previously been used as a transition state mimic of protein enzymes that catalyze the same reaction. Comparison of the 2.2 angstrom resolution structure of a vanadate-hairpin ribozyme complex with structures of precursor and product complexes reveals a rigid activ...
