Mice fed a diet low in many trace elements and raised in an environment where contamination from extraneous trace ele ments was controlled were given small amounts (5 jig/ml) of arsenite, germanate, stannous, or vanadyl ions in drinking water for their life times. Animals receiving arsenite had a significantly decreased incidence of all tumors, and of tumors of the lung, compared to those recei...

CONTEXT Oral vanadyl sulfate (vanadium) has potent hypoglycemic effects in diabetes animals, but data about its actions on pancreatic beta-cells (BC) ultrastructure is limited. OBJECTIVE Partial diabetic rats were treated with vanadium and insulin injection and their effects on BC ultrastructure are studied. METHODS Male rats were made diabetic with intravenous streptozotocin injection (STZ...

Vanadium belongs to the group of transition metals and is present in the air and soil contaminants in large urban agglomerations due to combustion of fossil fuels. It forms numerous inorganic compounds (vanadyl sulfate, sodium metavanadate, sodium orthovanadate, vanadium pentoxide) as well as complexes with organic compounds (BMOV, BEOV, METVAN). Depending on the research model, vanadium compou...

V2O5/SiO2 nanoparticles was prepared via an one-pot sol gel method from vanadyl- acetylacetonate and tetraethylorthosilicate in refluxing MeOH, followed by calcination at 700 °C for 2 hours. The resultant nanoparticles was characterized by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), TGA and FTIR techniques. Rapid and efficient ar...

The V(V) atom in the title compound, [V(C(8)H(9)N(2)O)(C(17)H(14)N(2)O(3))O]·CH(3)OH, is N,O-chelated by the benzoyl-hydrazidate anion and O,N,O'-chelated by the (benzoyl-hydrazono)propionate dianion. The octa-hedral trans-N(2)O(4) coordination geometry is completed by the vanadyl O atom. Two mononuclear complexes and two solvent mol-ecules are linked by O-H⋯O and O-H⋯N hydrogen bonds, generati...

Stepwise formation constants corresponding to 1:1 vanadyl complexes with methionine, phenyl­ alanine and threonine have been determined at 25 °C, and at various ionic concentrations, viz. 0.01, 0.1 and 0.3 M, maintained by the addition of potassium chloride solution. Thermodynamic stability constants have been obtained by extrapolation of log K values to zero ionic strength. Logarithms of the o...

Metal based drugs have successfully been used in the detection and treatment of a variety of diseases [1]. Despite the advantages in early diagnostic and treatment of cancer, there is essential to develop new alternative of drugs. A number of in vitro studies have revealed that vanadium shows its antitumor effects on various cell lines [2]. Moreover, it is shown that vanadium compounds may show...
