“…RESULTS: Compared with other microorganisms investigated, Acetobacter pasteurianus GIM1.158 was shown to be more effective for the reduction reaction, affording much higher yield, product enantiomeric excess (e.e.) and initial reaction rate. The optimal temperature, buffer pH, co-substrate and its concentration, substrate concentration, cell concentration and shaking rate were 35°C, 5.0, 500 mmol/L isopropanol, 40 mmol/L, 25 mg/mL and 120 r/min, respectively. …”

“…The results revealed that in the tumor human liver microsomes (HLMs), either V(max) (maximum reaction rate, R(max) for UGT1A1) or the clearance rates (V(max)/K(m), Clint) of UGT1A, UGT1A1, UGT1A4, UGT1A9 and UGT2B7 were significant lower than those of in the adjacent normal HLMs. …”

“…However, most CPE-based methods, including MTT and MTS assays, do not provide information on the initiation of CPE nor the changes in reaction rate of the virus propagation over time. Therefore, in this study we developed an RTCA method as an accurate and time-based screen for antiviral compounds against CHIKV. …”

“…We report the unprecedented self-assembly of R269A hlGPDH, dianions (X(2–) = FPO(3)(2–), HPO(3)(2–), or SO(4)(2–)), Gua(+) and GA into a functioning catalyst of the reduction of GA, and fourth-order reaction rate constants k(cat)/K(GA)K(X)K(Gua). The linear logarithmic correlation (slope = 1.0) between values of k(cat)/K(GA)K(X) for dianion activation of wildtype hlGPDH-catalyzed reduction of GA and k(cat)/K(GA)K(X)K(Gua) shows that the electrostatic interaction between exogenous dianions and the side chain of R269 is not significantly perturbed by cutting hlGPDH into R269A and Gua(+) pieces. …”

“…Our ab initio DFT calculations explicitly incorporating the e-beam in the theoretical model correlate with the chemTEM observations and give a mechanism for direct control not only of the type of the reaction but also of the reaction rate. Selection of the appropriate e-beam energy and control of the dose rate in chemTEM enabled imaging of reactions on a time frame commensurate with TEM image capture rates, revealing atomistic mechanisms of previously unknown processes.…”

“…It was observed that the specificity was lower in the sera of the participants living in clonorchiasis-endemic areas but without any parasite infection [67.5% (81/120) to 90% (108/120)], as compared to those from the non-endemic area [94% (47/50) to 98% (49/50)]. The cross-reaction rate varied from 14.93% (10/67) to 31.34% (21/67). …”
