Previous studies suggested that athletes' psychological capital level is related to life stress and burnout. Therefore, the purpose of this study was to explore the influences of university baseball athletes' psychological capital on their life stress and burnout and provide practical suggestions for athletes and coaches to reduce their life stress and burnout. In this study, we used athletes' control variables (grade, year of training experience, and training days per week) and psychological capital (self-efficacy, hope, optimism, and resilience) to predict their life stress and burnout.

The purpose of this study was to examine the relationships between sport participation level, flow, perceived health status and depression using gender and grades as control variables of college students in Taiwan. Based on previous research, the study established the proposed model: using sport participation level and flow experience as predicting variables, perceived health status and depression as dependent variables, and gender and grades as control variables. A total of 700 structured questionnaires were distributed to college students using convenience sampling among seven universities in Taiwan with a valid return rate of 86.

Due to differences in ethnic groups, there is much diversity in clinically important blood group antigens and genetic variants. Here, we developed a robust matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF)-based blood group genotyping method on MassARRAY system.

The phylogenetic relationships of Microhylidae, the third largest family of extant frogs, have been difficult to resolve. In the past decade, large amounts of sequence data have been deposited for almost every microhylid genus, but no study has attempted to combine these data to reconstruct a comprehensive phylogeny for this family. In this study, we sequenced 20 near-complete or partial microhylid mitochondrial genomes and integrated them with all available sequences of Microhylidae from GenBank to construct a supermatrix containing 121 genes (14 mitochondrial and 107 nuclear protein-coding genes).

ExoR has been proposed to inhibit the ExoS sensor through direct interaction in the periplasm. To understand how ExoR suppression of ExoS is relieved, which is required for the expression of ExoS/ChvI-regulated symbiosis genes, we characterized wild-type ExoR and ExoR95 mutant proteins.

Besides telomerase, telomere length is also regulated by several telomere-specific binding proteins. Tankyrase 1, a telomeric poly(ADP-ribose) polymerase (PARP), elongates telomere length by inhibiting TRF1 binding to telomeres.

The PROCLEIX ULTRIO assay (Ultrio) on the TIGRIS System (Novartis Diagnostics) was evaluated for its operational performance both for individual-donation testing (IDT) and in minipools of 4 (MP4) to develop a feasible solution.
Study Design And Methods: Analytical sensitivity was determined by testing WHO international standards.
The plasmid pJZ290 containing mariner transposon was used to mutagenize Sinorhizobium meliloti and 3000 transposon insertion mutants were subsequently screened for autoinducer-deficient (AI-deficient) mutants. One AI-deficient mutant YW1 was obtained by quantitative activity assay and qualitative TLC detection. In an effort to characterize the transposon insertions of autoinducer-deficient mutant YW1, we performed an arbitrary PCR and sequencing techniques to identify insertion sites.

Many subgroups of A, however, revealed ambiguous serologic typing results. This study aimed to delineate the molecular basis of the A3, Ax, and weak A phenotypes.

However, analysis of homologous comparison showed that there were at least four annotated acylated homoserine lactone (AHL) synthase genes from M.

The gene mxynB(64) was amplified by the method of PCR with the template of the genomic DNA of Thermotoga maritima MSB8, and cloned into the expression vectors of Escherichia coli and Pichia pastoris respectively. Xylanase B(40kD) was successfully expressed by the two heterologous protein expression systems with high-level production.

Methods: Expression of heparanase mRNA in gastric cancerous tissues and its corresponding adjacent tissues were detected by RT-PCR in forty-seven patients. Expression of c-met protein and microvessel density (MVD) were examined by immunohistochemcal staining.
