61) Due to the surrounding environment, for the tungstate-doped composite, this peak was broader due to the increased solubility of sodium tungstate dihydrate which led to probable hydrogen bonding due to water molecules adsorption.
The reaction was stopped by the addition of sodium tungstate (100 g/l) and sulfuric acid (0.
Washington, Aug 28 (ANI): Uncovering the molecular mechanisms of tungstate activity in diabetes, researchers have now identified the pathways through which sodium tungstate improves pancreatic function and beta cell proliferation.
Led by Professor Ramon Gomis at the Hospital Clinic de Barcelona in Spain, the researchers studied the effects of sodium tungstate on pancreatic gene expression in a rat model of diabetes, in order to discover the mechanisms that control the partial pancreatic regeneration induced by this treatment.
We purchased HPLC-grade methanol, acetonitrile, acetic acid, ammonium acetate, sodium tungstate, and perchloric acid from Merck.
Sample preparation was similar to our previous protocol (6), except that the volumes were decreased: 100 [micro]L of calibrator, quality control or patient sample (EDTA plasma) was treated with 10 [micro]L of perchloric acid (150 g/L),10 [micro]L sodium tungstate (250 g/L), and 50 [micro]L of internal calibrator solution (15 mg/L MPAC in acetonitrile).
