To investigate the efficiency of two new fast-acting enzymes, recombinant arylsulfatase (IMCS-PSF) and mutant β-glucuronidase from (IMCSzyme), in hydrolyzing specific terbutaline metabolites. Two purified novel enzymes are used to precisely determine the amount of each metabolite in urine at different time points after oral administration. After systematically evaluating the hydrolysis efficiency of the novel enzymes compared with commercially available enzymes, these recently developed enzymes were applied to establish the separate urine concentration profiles of terbutaline and each metabolite.

Ce3+ doped Y3Al5O12 : Ce3+ yellow phosphors are prepared by the high-temperature solid-state method, sol-gel method and hydrothermal-pyrolysis methods. The influences of the preparation methods on the phase, morphology and photoluminescence properties of the YAG : Ce3+ yellow phosphors are investigated by XRD, FESEM and PL, respectively. The results indicate that the three methods all realize the substitution of Ce3+ ions for Y3+ ions, and that the cubic crystalline structure of the Ce(3+)-doped YAG phosphors is unchanged.
