Application of the Spiritual Intelligence Self-Report Inventory (SISRI-24) Among Hong Kong University Students

The aim of this study was to examine the psychometric properties of the Chinese version of the Spiritual Intelligence Self-Report Inventory (SISRI-24). Two hundred thirteen undergraduate students in Hong Kong completed the Chinese SISRI-24, the Meaning of Life Questionnaire, the Metapersonal Self-Construal Scale, and the Satisfaction with Life Scale to allow examination of internal reliability and construct validity. Confirmatory factor analysis was also performed to examine whether the model of King and DeCicco (2009) fit our data. Our results indicated that the full scale of the Chinese SISRI-24 and its four subscales had acceptable internal reliability. The results also showed a positive relationship between spiritual intelligence and metapersonal self-construal. However, no significant relationship was reported between spiritual intelligence and life satisfaction. As such, construct validity was low to moderate. This study can be considered a foundation for understanding and measuring spiritual intelligence among undergraduate students in Hong Kong. Future research directions are suggested

The range of the tangential Cauchy-Riemann system on a CR embedded manifold

We prove that every compact, pseudoconvex, orientable, CR manifold of \C^n, bounds a complex manifold in the $C^\infty$ sense. In particular, the tangential Cauchy-Riemann system has closed range

Secretome Analysis of Skeletal Myogenesis Using SILAC and Shotgun Proteomics

Myogenesis, the formation of skeletal muscle, is a multistep event that commences with myoblast proliferation, followed by cell-cycle arrest, and finally the formation of multinucleated myotubes via fusion of mononucleated myoblasts. Each step is orchestrated by well-documented intracellular factors, such as cytoplasmic signalling molecules and nuclear transcription factors. Regardless, the key step in getting a more comprehensive understanding of the regulation of myogenesis is to explore the extracellular factors that are capable of eliciting the downstream intracellular factors. This could further provide valuable insight into the acute cellular response to extrinsic cues in maintaining normal muscle development. In this paper, we survey the intracellular factors that respond to extracellular cues that are responsible for the cascades of events during myogenesis: myoblast proliferation, cell-cycle arrest of myoblasts, and differentiation of myoblasts into myotubes. This focus on extracellular perspective of muscle development illustrates our mass spectrometry-based proteomic approaches to identify differentially expressed secreted factors during skeletal myogenesis

Roles of a novel splice variant of human IFI16 in innate immune response

Poster Presentation - Theme 4: Infection & immunityDNA from viral or bacterial pathogens activates innate immune response. The recognition of self-DNA would induce autoimmune diseases such as systemic lupus erythematosus (SLE). In human, AIM2 like receptors (ALRs) including AIM2, IFI16, IFIX and MNDA are DNA binding proteins implicated in DNA sensing. Most ALRs contain an N-terminal pyrin domain and C-terminal HIN200 domains. However, mouse SLE susceptibility locus p202 encodes only HIN200 domains. A human homolog of p202 was not found. Here, we identified and characterized a novel splice variant of human IFI16, which has a similar domain structure as mouse p202. We named it ...postprin

Impact of Probe Substrate Selection on Cytochrome P450 Reaction Phenotyping Using the Relative Activity Factor

ABSTRACT Accurately assessing the contribution of cytochrome P450 (P450) isoforms to overall metabolic clearance is important for prediction of clinical drug-drug interactions (DDIs). The relative activity factor (RAF) approach in P450 reaction phenotyping assumes that the interaction between P450-selective probes and testing systems is the same as the interaction of drug candidate with those systems. To test this assumption, an intersystem clearance ratio (ICR) was created to evaluate the difference in values between RAF-scaled intrinsic clearance (CL int ) and measured CL int in human liver microsomes (HLMs). The RAF value for CYP3A4 or CYP2C9 derived from a particular P450-selective probe reaction was applied to calculate RAF-scaled CL int for other probe reactions of the same P450 isoform in a crossover manner and compared with the measured HLM CL int . When RAF derived from midazolam or nifedipine was used for CYP3A4, the ICR for testosterone 6b-hydroxylation was 31 and 25, respectively, suggesting significantly diverse interactions of CYP3A4 probes with the testing systems. Such ICR differences were less profound among probes for CYP2C9. In addition, these RAF values were applied to losartan and meloxicam, whose metabolism is mostly CYP2C9 mediated. Only using the RAF derived from testosterone for CYP3A4 produced the expected CYP2C9 contribution of 72%-87% and 47%-69% for metabolism of losartan and meloxicam, respectively. RAF derived from other CYP3A4 probes would have attributed predominantly to CYP3A4 and led to incorrect prediction of DDIs. Our study demonstrates a significant impact of probe substrate selection on P450 phenotyping using the RAF approach, and the ICR may provide a potential solution

Molecular characterization of fluoroquinolone-resistant Mycobacterium tuberculosis clinical isolates from Shanghai, China

China is one of the countries with the highest prevalence of fluoroquinolone-resistant (FQ r) Mycobacterium tuberculosis. Nevertheless, knowledge on the molecular characterization of the FQ r M. tuberculosis strains of this region remains very limited. This study was performed to investigate the frequencies and types of mutations present in FQ r M. tuberculosis clinical isolates collected in Shanghai, China. A total of 206 FQ r M. tuberculosis strains and 21 ofloxacin-sensitive (FQ s) M. tuberculosis strains were isolated from patients with pulmonary tuberculosis in Shanghai. The phenotypic drug susceptibilities were determined by the proportion method, and the mutations inside quinolone resistance-determining region (QRDR) of gyrA and gyrB genes were identified by DNA sequence analyses. Among 206 FQ r M. tuberculosis strains, 44% (90/206) were multidrug-resistant isolates and 39% (81/206) were extensively drug-resistant isolates. Only 9% (19/206) were monoresistant to ofloxacin. In total, 79.1% (163/206) of FQ r isolates harboured mutations in either gyrA or gyrB QRDR. Mutations in gyrA QRDR were found in 75.7% (156/206) of FQ r clinical isolates. Among those gyrA mutants, a majority (75.6%) harboured mutations at amino acid position 94, with D94G being the most frequent amino acid substitution. Mutations in gyrA QRDR showed 100% positive predictive value for FQ r M. tuberculosis in China. Mutations in gyrB were observed in 15.5% (32/206) of FQ r clinical isolates. Ten novel mutations were identified in gyrB. However, most of them also harboured mutations in gyrA, limiting their contribution to FQ r resistance in M. tuberculosis. Our findings indicated that, similar to other geographic regions, mutations in gyrA were shown to be the major mechanism of FQ r resistance in M. tuberculosis isolates. The mutations in gyrA QRDR can be a good molecular surrogate marker for detecting FQ r M. tuberculosis in China. © 2012 Elsevier Inc.postprin
