Examining the Effect of Narrative Features and Thematic Music in an Audio-Based Exergame

Audio-based exergames are beneficial in that they allow users to exercise in an eyes-free and hands-free environment. In this study, we explored two audio-based exergame elements, narrative features and thematic music, that can impact exercise amount (step count and duration) and exercise enjoyment. We conducted a two-week long between-subjects study with 43 young adults and 43 middle-aged adults using SPORTIFY, an audio-based exergame. Our experimental results showed that (1) Using narrative features had a significant main effect on exercise amount and exercise enjoyment both for young adults and middle-aged adults. (2) Using thematic music had no significant main impact on exercise amount and exercise enjoyment both for young adults and middle-aged adults. (3) A significant interaction effect for exercise amount was observed in middle-aged adults, whereas a significant interaction effect for exercise enjoyment was observed in young adults.</p

Table_1_Identification of isomeric cyclo(leu-pro) produced by Pseudomonas sesami BC42 and its differential antifungal activities against Colletotrichum orbiculare.docx

Pseudomonas spp. produce various antimicrobial substances, including cyclic peptides, which have been shown to suppress fungal pathogens. In a previous study, Pseudomonas sesami BC42 was selected to control anthracnose caused by Colletotrichum orbiculare in cucumber plants, and the bioactive extract of strain BC42 inhibited fungal growth and development. In this work, preparative thin-layer chromatography was conducted to identify the antifungal compounds in the extract of strain BC42, and the portion of the extract that exhibited antifungal activity was further analyzed by gas chromatography–mass spectrometry. Three different isomers of the cyclic dipeptide, cyclo(Leu-Pro), were identified: cyclo(l-Leu-l-Pro), cyclo(d-Leu-d-Pro), and cyclo(d-Leu-l-Pro). Among these, 100 μg/mL of cyclo(l-Leu-l-Pro) significantly and more effectively inhibited the germination of conidia and appressorium formation and reduced leaf lesion size caused by C. orbiculare, relative to the control; cyclo(d-Leu-d-Pro) significantly reduced conidia germination and lesion occurrence, however, cyclo(d-Leu-l-Pro) did not exhibit antifungal activity. Therefore, the cyclo(l-Leu-l-Pro) and cyclo(d-Leu-d-Pro) derived from P. sesami BC42 may be a promising candidate for biocontrol applications in agriculture.</p

Data_Sheet_1_Electrochemical Mechanism of Tellurium Reduction in Alkaline Medium.pdf

A systematic electrochemical study was conducted to investigate the reduction of tellurium (Te) in alkaline solutions. The effect of various parameters, including tellurite ion concentration, applied potential, and pH was investigated by both linear sweep voltammograms (LSVs) and electrochemical quartz crystal microbalance (EQCM). EQCM was essential to understand the reduction of Te(0) to soluble Te22-(-I) or Te2−(-II). The Tafel slopes for two Te reduction reactions [i.e., Te(IV) to Te(0) and Te(0) to Te(-I)] indicated that the electrochemical reduction of Te is strongly dependent on solution pH, whereas it is independent of the concentration of TeO32-. At relatively weaker alkaline solutions (i.e., pH ≤ 12.5), the discharge of Te(OH)3+ was determined to be the rate-limiting step during the reduction of Te(IV) to Te(0). For the reduction of Te(0) to Te(-I), the reaction follows a four-step reaction, which consisted of two discharge and two electrochemical reactions. The second discharge reaction was the rate-limiting step when pH ≤12.5 with the Tafel slope of 120 mV/decade. At a higher pH of 14.7, the Tafel slope was shifted to be 40 mV/decade, which indicated that the rate-limiting step was altered to the second electrochemical reaction. Te(0) deposits were found either on the surface of an electrode or in the solution depending on pH due to the different rate-limiting reactions, revealing that pH was a key parameter to dictate the morphology of the Te(0) deposits in alkaline media.</p

Gelatin–Gallic Acid Microcomplexes Release GO/Cu Nanomaterials to Eradicate Antibiotic-Resistant Microbes and Their Biofilm

Wound-infecting bacteria are typically Pseudomonas aeruginosa and Staphylococcus epidermidis, both of which form biofilms and become resistant to antibiotics. To solve this problem, copper nanoparticles (Cu) on graphene oxide (GO) nanosheets were used as antibacterial materials. Since the excessive use of antibacterial substances is fatal to normal tissues, GO/Cu was encapsulated with a gelatin complex to lower the cytotoxicity. Among the catechol-based substances, gallic acid (GA), which has anti-inflammatory and antibacterial properties, was used in this study to impart stability to the gelatin complex. Gelatin (GE) and gallic acid (GA) were combined by a crosslinking method using 1-ethyl-3-(3-dimethylaminopropyl)­carbodiimide (EDC)/N-hydroxysuccinimide (NHS) as a crosslinker, and the crosslinking was confirmed by Fourier transform infrared (FT-IR), 1H NMR, and the fluorescence property of GA. The GO/Cu@GE–GA microcomplexes exhibited more antibacterial effect against Gram-positive bacteria (S. epidermidis) and Gram-negative bacteria (P. aeruginosa) than when GO/Cu alone was used, and the antibiofilm effect was also confirmed. The cytotoxicity evaluation for human skin cells (human dermal fibroblast (HDF)) at the same concentration showed that it had low cytotoxicity and biocompatibility. This study shows the potential of antimicrobial gelatin microcomplex in prohibiting infectious bacteria and their biofilms and controlling the release of antimicrobial substances
