This study presents the investigation and comparison the influence of VOSO4 [V(IV)I, Na3VO4 and NaVO3 [V(V)] in the range of 0.5-20.0 microM on the rat hepatoma cell line H35-19. The cells were tested with crystal violet (N-hexamethylpararosaniline), and counted in a Bürker chamber to determine their rate of proliferation, while the survival level was established with neutral red and MTT [bromi...
The hypoglycemic effects after oral administration of vanadium have been studied previously in many species such as rats, mice and even humans. However, there has been no prior report on the glucose lowering effect of vanadium on diabetic dogs. Therefore, the purpose of this study was to evaluate the hypoglycemic effects of oral vanadium on diabetic dogs. Diabetes mellitus in the dogs studied w...
The characteristics of doxorubicin handling have been studied in the cultured kidney epithelial cell line LLC-PK1, which has structure and function similar to those of renal tubular cells and expresses P-glycoprotein. The uptake of doxorubicin by LLC-PK1 cells was time dependent, reaching a steady state at about 4 hr, and reduced at low temperature; the initial uptake was saturable. The efflux ...
Deactivation kinetics of a V/Ti-oxide catalyst was studied in partial oxidation of toluene to benzaldehyde (BA) and benzoic acid (BAc) at 523–573 K. The catalyst consisted of 0.37 monolayer of VOx species and after oxidative pre-treatment contained isolated monomeric and polymeric metavanadate-like vanadia species under dehydrated conditions as was shown by FT Raman spectroscopy. Under the reac...
Recent studies indicate the role of the micronutrient vanadium in chemoprevention in many animal models, human cancer cell lines, and also in xenografted human carcinomas of the lung, breast, and gastrointestinal tract. The present studies were undertaken to ascertain the antineoplastic potential of vanadium in a defined model of mammary carcinogenesis. Female Sprague-Dawley rats, at 50 days of...
This research reports a facile ultrasonic approach for the synthesis of iron vanadate (FeVO4) nanoparticles with the aid of ammonium metavanadate (NH4VO3) and Fe(NO3)3.9H2O as the starting reagents without adding external surfactant, capping agent or template in an aqueous solution. Furthermore, to examine the solar cell application of as-synthesized iron vanadate (FeVO4) nanoparticles, FTO/TiO...
Globodera ellingtonae was detected in Oregon in 2008. In order to make decisions regarding the regulation of this nematode, knowledge of its biology is required. We determined the host status of a diversity of potato (Solanum tuberosum) varieties in soil-based experiments and identified hatching stimulants in in vitro hatching assays. 'Russet Burbank,' 'Desiree,' 'Modac,' 'Norland,' 'Umatilla,'...
