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.

Article Synopsis
  • - The systematic review aimed to assess how well combined topical and intravenous tranexamic acid (TXA) works at reducing blood loss during total knee arthroplasty (TKA) compared to using either method alone or a control.
  • - A comprehensive search for relevant randomized controlled trials (RCTs) was conducted, and studies included focused on patients undergoing primary TKA, measuring outcomes such as total blood loss and the need for transfusions, while also monitoring for safety concerns like deep venous thrombosis (DVT).
  • - The analysis of 15 studies involving 1,495 patients showed that the combined use of topical and intravenous TXA significantly reduced blood loss, with a mean difference indicating a considerable decrease in blood loss

Article Synopsis
  • * Experiments on microwave pyrolysis reveal that optimal conditions include 800W power, 40 minutes of pyrolysis time, coal particle sizes of 5-10 mm, and a gas flow rate of 0.4 L/min, leading to yields of 62.2% for bluecoke and 26.8% for liquid products.
  • * Adjusting variables like microwave power, pyrolysis time, and coal particle size significantly impacts the quality of coal tar, with

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.
