The budC gene coding for a new meso-2,3-butanediol dehydrogenase (BDH) from Serratia marcescens H30 was cloned and expressed in Escherichia coli BL21(DE3), purified, and characterized for its properties. The recombinant BDH with a molecular weight of 27.4 kDa exhibited a reversible transformation between acetoin and 2,3-butanediol. In the presence of NADH,(More)
Web-based knowledge communities (WKCs) have become prevalent in recent years for individuals with similar interests to collectively engage in knowledge acquisition and exchange in a global context. The growing popularity of WKCs and their fast penetration into almost all aspects of life call for more research on this important area. In this study, we(More)
The Sarbanes-Oxley Act of 2002 ͑SOX͒ created a resurgence of organizational focus on internal controls. In this study, we examine the extent to which the information technology ͑IT͒ controls suggested by the ISO 17799 security framework have been integrated into organizations' internal control environments. We collected survey data from 636 members of the(More)
Serratia sp. T241, a newly isolated xylose-utilizing strain, produced three 2,3-butanediol (2,3-BD) stereoisomers. In this study, three 2,3-butanediol dehydrogenases (BDH1-3) and one glycerol dehydrogenase (GDH) involved in 2,3-BD isomers formation by Serratia sp. T241 were identified. In vitro conversion showed BDH1 and BDH2 could catalyzed (3S)-acetoin(More)
Recent studies have indicated that the inflamma-tory microenvironment plays a significant role in colorectal cancer (CRC). The interleukin‑6/signal transducer and activator of transcription 3 (IL-6/STAT3) signaling pathway mediates the proliferative and anti‑apoptotic activities required for oncogenesis under inflammatory conditions; thus, suppressing tumor(More)
OBJECTIVE To investigate the effectiveness and safety of Tai Chi Chuan (TCC) on physical and psychological health of college students. METHODS Two hundred six college students were recruited and randomly allocated to a control group or a TCC exercise group in an equal ratio. Participants in the control group were instructed to maintain their original(More)
BACKGROUND The physical and mental health of college-age youths tends to continuously decline around the world. It is therefore important to promote health during this period. As a traditional Chinese mind-body exercise, Tai Chi Chuan (TCC) may be an available selection. However for the college student population, the evidence is unclear as to whether TCC(More)
Pragmatics is included in one of four communicative competences (Canale, 1980). It is necessary and important to teach pragmatics at school in our globalized world in order to avoid as much as misunderstanding, which is likely to stem from cultural difference. As a result, greater importance should be attached to diverse customs and pragmatics. This(More)
