Simulation-based learning that focuses on the development and assessment of communication and counseling skills can help nursing students achieve better skill performance and gain self-confidence with decision-making ability. It is unknown whether virtual simulation as an instructional design significantly improves educational outcomes than a traditional lecture with low-fidelity simulation in students.The aim was to explore the effect of a virtual simulation-based educational smartphone application on nursing students' beliefs and self-efficacy in communicating with patients about complementary and alternative medicine (CAM) use.A quasi-experimental study with pretest-posttest nonequivalent control group design.A total of 101 nursing students, who were in their second or third-year nursing program at a Southern Taiwan university volunteered to participate in the academic year 2020-2021. Participants were assigned to an experimental or control group in an elective course.All participants received a 4-hour lecture that included an in-class lecture with low-fidelity simulation (paper-based scenarios) about the risk-benefit assessment of a patient's CAM use. The experimental group received a series of 13 virtual simulation exercises with clinical scenarios by means of a smartphone application. Data from belief and self-efficacy scales were collected at the beginning and end of the course from September 2020 to February 2021. Descriptive and inferential statistics were analyzed using the IBM® SPSS® version 23.0.Although both groups significantly improved their belief and self-efficacy scale scores, the experimental group had significant differences in overall self-efficacy in communicating with patients about CAM use compared with the control group, specifically the CAM perceptions and self-confidence scores.Although both in-class and virtual simulation improved nursing students' belief and self-efficacy, the virtual simulation-based educational app is effective as an adjunct learning tool in significantly increasing nursing students' self-efficacy in communicating with patients about CAM use to help minimize their risks.

Background Interactions between transcriptional inducers of cytochrome P450 (CYP450) enzymes and therapeutic drugs may be prevented by antagonizing the activation of a nuclear receptor (NR), pregnane X receptor (PXR, NR1I2), thus improving therapeutic efficacy. Purpose In the present study, we aim to identify that ursolic acid (UA), a widely distributed pentacyclic triterpene, may act as an effective antagonist of PXR and its sister NR receptor, constitutive androstane receptor (CAR, NR1I3). Methods The hepatocellular carcinoma cell line, HepG2, was used to evaluate the promoter activity of PXR and CAR target genes, CYP3A4 and CYP2B6, respectively. Catalytic activities, mRNA, and protein expression of CYP3A4 and CYP2B6 were evaluated in a differentiated HepaRG cell line. Coregulation of PXR with coregulators on CYP3A4 promoter response elements was also been characterized. Results Transient transfection assays showed that UA effectively attenuated CYP3A4 and CYP2B6 promoter activities mediated by rifampin (RIF, human PXR agonist) and CITCO (human CAR agonist). These inhibitory effects were well correlated with the expression and catalytic activities of CYP3A4 and CYP2B6. Furthermore, the interaction of co-regulators with PXR and the transcriptional complexes in the CYP3A4 promoter activity and CYP3A4 promoter xenobiotic response element (everted repeat 6, ER6), respectively, were disrupted in the presence of UA. UA showed an antagonistic effect against PXR, and reversed the cytotoxic effects of isoniazid (INH) induced by RIF. Taken together, these results show that UA inhibits the transactivation effects of PXR and CAR, and reduces the expression and function of CYP3A4 and CYP2B6. Conclusion The present study suggests that UA could be a powerful agent for reducing potentially dangerous interactions between transcriptional inducers of CYP enzymes and therapeutic drugs.

Alteration of elbow range of motion (ROM) has been observed in baseball pitchers. This study aims to compare dominant elbow ROM between early-puberty, late-puberty, and young-adult pitchers.We recruited 62 pitchers, consisting of 17 early-puberty (mean age 13.1 years old), 22 late-puberty (mean age 17.7 years old), and 23 young-adult players (mean age 19.4 years old). Dominant elbow ROMs was measured. One-way ANOVA was used to compare the differences in elbow ROM variables between 3 groups.Late-puberty pitchers exhibited a significantly lower elbow hyperextension and flexion than early-puberty or young-adult pitchers (P .05). Valgus angle was significantly lower in young-adult (7.7°±5.5°) versus early-puberty (12.1°±2.3°) and late-puberty pitchers (13.0°±4.1°; P .05). Young-adult pitchers had the largest forearm supination range (101.2°±18.1°), followed by early-puberty (82.5°±6.5°; P .05) and late-puberty pitchers (70.6°±15.8°). Elbow flexion-hyperextension total range was smallest in late-puberty pitchers (130.3°±7.4°), followed by young-adult (142.6°±9.3°) and early-puberty pitchers (144.6°±8.3°; P .05). Forearm pronation-supination total range was also smallest in late-puberty pitchers (142.0°±20.3°), followed by early-puberty (159.8°±9.5°) and young-adult pitchers (177.2°±20.8°; P .05).These results indicate that careful monitoring of the elbow and forearm range of motion should be undertaken in adolescent baseball pitchers to prevent and or minimize injury risk.

This study used the mitochondrial DNA cytochrome b and control region sequences to examine the population genetic structure of Microphysogobio brevirostris, an endemic cyprinid species in northern Taiwan. In total, 90 specimens were collected from six populations belonging to four major rivers. All haplotypes were identified as two major clades (Clades N and S), exhibiting a southern and a northern distribution. The results of statistical dispersal-vicariance analysis (S-DIVA) revealed that two vicariance events and one dispersal event shaped the phylogeographic pattern of M. brevirostris. These results suggest that the ancestral populations of M. brevirostris are widely distributed throughout northern Taiwan, north of the Miaoli Plateau. The ancestral populations then diverged into two clades (N and S) by the raising of the Taoyuan Plateau. Finally, two major rivers of the S clade diverged and dispersed into adjacent rivers. Besides, our results revealed that Microphysogobio alticorpus and M. brevirostris colonized Taiwan during the same ice age through different colonization routes.

The reproductive biology of the black marlin, Istiompax indica, was assessed by examining 4762 fish (458 ovary samples) caught by offshore longliners off southwestern and eastern Taiwan during 2004–2007. The overall sex ratio (0.67 off southwestern and 0.86 off eastern Taiwan) was significantly different from 0.5 (p

Phellinus linteus and its constituent hispolon induce potent anti-inflammatory activity in macrophages. Efficient production of the effective constituent and the biological function of P. linteus in the regulation of innate sensing have rarely been investigated. The aim of this study was to efficiently manufacture P. linteus -fermented broth containing the effective constituent, hispolon, and evaluate its immunoregulatory functions in macrophages. Four distinct fermented broths (PL1–4) and the medium dialyzate (MD) were prepared to screen suitable culture conditions for the mycelial growth of P. linteus . The P. linteus -fermented broth exhibited a dose-responsive inhibition of lipopolysaccharide (LPS)-induced nitric oxide (NO) production by murine macrophages. In addition, the P. linteus -fermented broths suppressed macrophage LPS-mediated nuclear factor (NF)-κB activity and tumor necrosis factor (TNF)-α. Among the tested samples from P. linteus , PL4 contained vast amounts of hispolon and showed the greatest anti-inflammatory activity in both the RAW264.7 cells and murine primary peritoneal exudate macrophages (PEMs). This study demonstrates that the purification of the effective constituent from P. linteus -fermented broth may enable the production of a potent therapeutic agent for anti-inflammation in macrophages.

Objectives To determine the immediate effects of applied forearm Kinesio taping on maximal grip strength and force sense of healthy collegiate athletes. Design Single group, repeated measures study. Setting Clinical sports medicine laboratory at a university hospital. Participants Twenty-one healthy collegiate athletes voluntarily participated in this study. All subjects were male (average height: 181.24 ± 7.60 cm; average body weight: 72.86 ± 7.03 kg; average age: 20.86 ± 2.59 years). Main Outcome Measures First, maximal grip strength of the dominant hand was assessed by hand-held dynamometer. Then, 50% of maximal grip strength was established as the reference value of force sense. Absolute and related force sense errors and maximal grip strength were measured under three conditions: (1) without taping; (2) with placebo taping; and (3) with Kinesio taping. Results Results revealed no significant differences in maximal grip strength between the three conditions ( p = 0.936). Both related and absolute force sense errors in grip strength measurements significantly increased the accuracy of the results under the three conditions (related force sense errors: p p Conclusion Forearm Kinesio taping may enhance either related or absolute force sense in healthy collegiate athletes. However, Kinesio taping did not result in changes in maximal grip strength in healthy subjects.
