There are many problems in the routine badminton teaching; there are mainly three aspects in college teaching. One is that the hardware equipment related to badminton is not enough; the second is that the badminton teaching does not meet the educational goals; the third is that the participation of college students is not high, which is no longer suitable for the current practical teaching. In order to improve the teaching method of badminton and improve the students' special performance of badminton, this paper studies the teaching of badminton based on multimedia environment. 82 students majoring in badminton were randomly divided into two classes. The experimental class (n = 41) used multimedia badminton teaching, and the control class (n = 41) used traditional badminton teaching, which lasted for one semester. Before and after the experiment, the students' physical fitness and badminton performance were tested. And the two classes of students were to send questionnaires to investigate interest in learning badminton and teaching satisfaction. The results of standing long jump, 50 m, and 800 m of the experimental class were improved by 0.2 m, 1.13s, and 16.25s, respectively. This shows that the physical quality and badminton performance of the experimental class under the multimedia environment are better than those of the control class under the general teaching. In the experimental class, 16 students are very interested in learning badminton, and 22 students are very satisfied with the multimedia teaching method; in the control class, only 9 students are very interested in learning badminton, and only 13 students are very satisfied with the traditional teaching method, which shows that the interest and satisfaction of students in the experimental class under the multimedia environment are higher than those in the control class under the traditional teaching.
A field trial of the use of expanded polystyrene beads (EPSB) to control the breeding of mosquito larvae in household septic tanks was conducted in Sarawak. One week after treatment, the breeding of Culex quinquefasciatus and Aedes albopictus was reduced by 100% and 68.7% respectively. For both species combined, a 57.25% reduction in the adult emergence rate was achieved. No adult was caught in the emergence trap one month after treatment. A reduction in mosquito biting rates was reported by 87.3% of respondents. All households regarded the EPSB treatment as effective. This study has reduced the relatively high infestation rate of A. albopictus in the septic tanks to 16-20%. The EPSB treatment is feasible and practical. Post-treatment assessment using adult emergence traps and the implications for the vector control programme of the local authority are discussed.
Nanogels offer hope for precise drug delivery, while addressing drug delivery hurdles is vital for effective prostate cancer (PCa) management. We developed an injectable elastin nanogels (ENG) for efficient drug delivery system to overcome castration-resistant prostate cancer (CRPC) by delivering Decursin, a small molecule inhibitor that blocks Wnt/βcatenin pathways for PCa. The ENG exhibited favourable characteristics such as biocompatibility, flexibility, and low toxicity. In this study, size, shape, surface charge, chemical composition, thermal stability, and other properties of ENG were used to confirm the successful synthesis and incorporation of Decursin (DEC) into elastin nanogels (ENG) for prostate cancer therapy. In vitro studies demonstrated sustained release of DEC from the ENG over 120 h, with a pH-dependent release pattern. DU145 cell line induces moderate cytotoxicity of DEC-ENG indicates that nanomedicine has an impact on cell viability and helps strike a balance between therapeutics efficacy and safety while the EPR effect enables targeted drug delivery to prostate tumor sites compared to free DEC. Morphological analysis further supported the effectiveness of DEC-ENG in inducing cell death. Overall, these findings highlight the promising role of ENG-encapsulated decursin as a targeted drug delivery system for CRPC.
