Effect of sodium vanadate
Platelet-activating factor (1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine, AGEPC) and sodium vanadate (a phosphotyrosine phosphatase inhibitor) induced a timeand concentration-dependent increase in phosphotyrosine in several proteins and stimulated prostaglandin (PG) E2 production in cultured rat Kupffer cells. In addition, vanadate induced a decrease in the surface expression of AGEPC recepto...
متن کاملThe insulin-like effect of sodium vanadate
Sodium vanadate has several insulin-like effects. To determine whether vanadate acts via the insulin receptor, I investigated the effect of vanadate on glucose transport (2-deoxyglucose uptake) in adipocytes that had been treated to decrease the number of insulin receptors. (1) Trypsin (100 ,tg/ml) caused > 95% loss of 1251-insulin binding and rendered glucose transport resistant to both insuli...
متن کاملTime and Composition Dependent Electrical Conductivity of Vanadate Glasses Showing Both Cationic Conduction and Electronic Conduction*
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...
متن کاملStructural and dc electrical conductivity studies of SnO substituted lead vanadate glasses
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...
متن کاملRocking-Chair Configuration in Ultrathin Lithium Vanadate-Graphene Hybrid Nanosheets for Electrical Modulation
The ability to control electronic property of a material by externally applied voltage is greatly anticipated in modern electronics, and graphene provide potential application foreground for this issue on account of its exotic ambipolar transport property. In this study, we proposed that inorganic-graphene intercalated nanosheet is an effective solution to optimize the transport property of gra...
