The alterations in the levels/activities of selected biomarkers for detecting kidney toxicity and in the levels of some oxidative stress (OS) markers and elements were studied in male rats to evaluate biochemically the degree of kidney damage, investigate the role of OS in the mechanism of functional renal disorders, reveal potential biomarkers of renal function, and assess the renal mineral ch...

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 ...

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...

Background: Since the freezing method was offered, much effort has been done to improve the freezing conditions in different studies and the impact of different freezing methods and mediums on oocyte, embryo and ovarian tissues has been examined. Based on studies, minerals play an important role in oocyte maturation and subsequent embryo development. Vanadium is one of the minerals, which is ve...

Glasses of the system x (SnO) (50-x)PbO : 50V2O5 were prepared by melt quenching in the range x = 0 mole% to 15 mole%. Measurements are reported for dc electrical conductivity for the above compositions in the temperature range 300K-500K. The experimental results are analyzed with reference to various theoretical models proposed for dc electrical conduction in amorphous semiconductors. The anal...
