A new catalytic spectrophotometric method for the determination of trace vanadium(Ⅴ) has been developed.This method is based on the catalytic oxidation of curcumin by potassium bromate with Tween-80 as a solubilized agent in sulfuric acid solution.The detection limit of the method is 2.6×10 -3...
A randomised double blind placebo controlled crossover (鈥渨ithin subjects鈥 design was used. The intervention was four days of 20 mg sustained release oral morphine or corresponding placebo. No washout period was included. Laxatives were provided as needed. Participants were 48 patients who had ...

The active areas versus the PCE of the 1.0 mM Tween 20 PSCs prepared by the two different methods are shown in Figure 6b,c. When the active area increased, the performance of the spin-coated PSC dropped dramatically, with a large standard deviation. However, the efficiency of large-area ...
(p< 0.05). The effect of using SDC versus Span 80 as a second surfactant with Tween 80 was found to be insignificant with respect to the sizes of the micelles. The F3 formulation (containing 500 mg Span) exhibited a significantly lower particle size (p< 0.05) than the F2 formulation (...
The polymerization potential is various among 1.6 V and 1.7 V versus SCE for applied current densities: 3 mA/cm2 and 5 mA/cm2 with 1:1, 3:5 and 5:1 molar ratios for NMPY-Tw20 and 3MT. The surfactant Tween 20 dopant ion used in electropolymerization (presented in methylpyrrole) can...
The percent rate of control was calculated from the 6-OH-PTX production rates in the presence of the PE versus its absence (blank control). QCT (10 µM) was used as the positive control of CYP2C8 inhibition. The IC50s of Tween 80 and EL-35 on CYP2C8 were determined by ...
