These governments consequently allocate most resources in these foresight activities. As a result, the paper mainly develops the evaluation framework of technology foresight program, by integrating the concepts of evaluation and logic framework with the experience of foresight evaluation from developed countries, for instance European Union, Britain etc., to realize the outcomes of implementing foresight activities. Taking Sweden as a case study, the paper is also proposed to show the effectiveness of this new framework

    Urinary tract infection (UTI) is traditionally classified as community-acquired (CA) and hospital-acquired (HA). Community-onset health care-associated (HCA) infection is a new category that has gained increasing attention. The study aimed to compare the disk susceptibility of nonrepetitive Escherichia coli urinary isolates from HCA-UTI (nĀ =Ā 100) with that of E.Ā coli isolates from CA-UTI (nĀ =Ā 85) and HA-UTI (nĀ =Ā 106). We found that the susceptibility pattern of HCA-UTI E. coli isolates was similar to that of HA-UTI E. coli isolates, but significantly different from that of CA-UTI E. coli isolates. In particular, the proportion of extended-spectrum Ī²-lactamase-producing isolates was significantly higher in HCA-UTI than that in CA-UTI (30.0% vs. 3.5%, pĀ <Ā 0.001). We recommend that when treating HCA-UTI, it is necessary to take urine cultures for susceptibility testing to guide definite antibiotic therapy

    An efficient DNA isolation method for tropical plants

    Due to interfering components such as polysacharrides, polyphenols, etc, DNA isolation from tropical plants had been challenging. We developed a safe, universal and efficient DNA extraction method, which yielded high-quality DNA from 10 tropical plants including cassava, rubber tree, banana, etc. In the extraction buffer, 2 M NaCl was used to provide a high ionic strength reaction environment, ethylenediaminetetraacetic acid (EDTA), lauroyl sarcosine (LSS) and cetyl trimethyl ammonium bromide (CTAB) could inhibit DNase activity effectively, polyvinylpolypyrrolidone (PVPP) produced a deoxidized reaction environment, and borax enhanced the precipitation of interfering compounds. Ordinary reagents like Ī²-mercaptoethanol, chloroform and phenol were unnecessary in this protocol, which made it safe and friendly to use. PCR and EcoR I enzyme restriction digestion results show that the obtained DNA is good enough for downstream analysis. In conclusion, this protocol is expected to be a preferable DNA extraction protocol for tropical plants.Keywords: DNA extraction, tropical plants, cetyl trimethyl ammonium bromide (CTAB)African Journal of Biotechnology Vol. 12(19), pp. 2727-273

    Get PDF
    This study highlights the innovation management and learning perspective of a firmā€™s innovative capability. The model proposed in this study examines the relationships among competence exploitation, competence exploration, transformative learning, innovation, and performance. This study presents empirical results from 225 service industry in Taiwan. First, the innovative capability factors positively affect transformative learning include competence exploitation and competence exploration. Transformative learning in turn has positive effects both on innovation and performance. Secondly, the rank order effects on innovation are competence exploitation, competence exploration, and transformative learning, respectively. The rank order effects on performance are competence exploration, competence exploitation, and transformative learning, respectively. Finally, transformative learning is the mediating effect of competence exploitation and competence exploration on innovation and performance

    [[abstract]]The major purpose of this study was to identify the effects of personality on individual exercise motivation and exercise participation, which then influences quality of life. A comprehensive model was developed, based on an extensive literature review, and empirically tested using members of fitness centers from Taiwan, Europe and the United States as respondents. The results indicate that individuals with a positive personality tend to have higher levels of exercise motivation and exercise participation. Personality and exercise participation then impacted on individualsā€™ quality of life, in terms of physical health improvement, psychological health improvement, and sexual satisfaction. The study results offer valuable suggestions not only to marketing managers of fitness centers but also to government officers to promote health and quality of life through stimulating exercise motivation and exercise participation

    A new analysis tool for individual-level allele frequency for genomic studies

    <p>Abstract</p> <p>Background</p> <p>Allele frequency is one of the most important population indices and has been broadly applied to genetic/genomic studies. Estimation of allele frequency using genotypes is convenient but may lose data information and be sensitive to genotyping errors.</p> <p>Results</p> <p>This study utilizes a unified intensity-measuring approach to estimating individual-level allele frequencies for 1,104 and 1,270 samples genotyped with the single-nucleotide-polymorphism arrays of the Affymetrix Human Mapping 100K and 500K Sets, respectively. Allele frequencies of all samples are estimated and adjusted by coefficients of preferential amplification/hybridization (CPA), and large ethnicity-specific and cross-ethnicity databases of CPA and allele frequency are established. The results show that using the CPA significantly improves the accuracy of allele frequency estimates; moreover, this paramount factor is insensitive to the time of data acquisition, effect of laboratory site, type of gene chip, and phenotypic status. Based on accurate allele frequency estimates, analytic methods based on individual-level allele frequencies are developed and successfully applied to discover genomic patterns of allele frequencies, detect chromosomal abnormalities, classify sample groups, identify outlier samples, and estimate the purity of tumor samples. The methods are packaged into a new analysis tool, ALOHA (<b>A</b>llele-frequency/<b>L</b>oss-<b>o</b>f-<b>h</b>eterozygosity/<b>A</b>llele-imbalance).</p> <p>Conclusions</p> <p>This is the first time that these important genetic/genomic applications have been simultaneously conducted by the analyses of individual-level allele frequencies estimated by a unified intensity-measuring approach. We expect that additional practical applications for allele frequency analysis will be found. The developed databases and tools provide useful resources for human genome analysis via high-throughput single-nucleotide-polymorphism arrays.

    Background: To study the protein profile of the serum exosomes of patients with coronary artery aneurysms (CAA) caused by Kawasaki disease (KD). Methods: Two-dimensional electrophoresis (2-DE) was used to identify proteins from the exosomes of serum obtained from children with CAA caused by KD, as well as healthy controls. Differentially expressed proteins were identified using matrix-assisted laser desorption/ionization time-of-flight/timeof-flight mass spectrometry (MALDI-TOF/TOF MS) analysis. Results: Thirty two differentially expressed proteins were identified (18 up-regulated and 14 downregulated) from serum exosomes of children with CAA and were compared to healthy controls. The expression levels of 4 proteins (TN, RBP4, LRG1, and APOA4) were validated using Western blotting. Classification analysis and proteinā€“protein network analysis showed that they are associated with multiple functional groups, including host immune response, inflammation, apoptotic process, developmental process, and biological adhesion process. Conclusions: These findings establish a comprehensive proteomic profile of serum exosomes from children with CAA caused by KD, and provide additional insights into the mechanisms of CAA caused by KD
