        The Effectiveness of the Reflection-Based Interactive Teaching Approach on Students’ Reading Comprehension Achievement

        Nwe Nwe Htun,Than Nu,Tun Zaw Oo 순천대학교 교육과학연구소 2023 현장수업연구 Vol.4 No.1

        This study aimed to investigate the effectiveness of the Reflection-Based Interactive Teaching (RBIT) approach on students’ reading comprehension achievement in Myanmar. RBIT means applying the interactive teaching approach in Oo and Habók's (2020) reflective teaching model for reading comprehension based on planning, acting, reflecting, and evaluating. 458 grade-10 students from Myanmar were selected as participants in this study by applying the randomized cluster trial. The quasi-experimental research design was applied together with some analyses such as structural equation modeling by the AMOS software, item-difficulty index by the Quest program, inferential statistics (t-tests and effect sizes), and some reliability/validity measures. The findings showed a significant difference between the experimental group with the treatment with the RBIT and the control group without the RBIT approach. Furthermore, it was also found that teachers' reflections had no significant effects on students' appreciative reading comprehension. This study is of great importance for teachers and students from the field of English Language Teaching (E.L.T).

        Effect of cytochrome P450 3A5 polymorphism on the pharmacokinetics of tacrolimus in renal transplant recipients

        Yi Yi Htun,Nwe Nwe Than,Htar Kyi Swe 대한이식학회 2020 Korean Journal of Transplantation Vol.34 No.1

        Background: Renal transplant is an effective treatment option for end-stage kidney disease and tacrolimus is one of the most commonly used immunosuppressant drugs in renal transplant patients. Tacrolimus is a substrate of cytochrome P450 3A5 (CYP3A5), and a narrow therapeutic index and large inter-individual variability. The objective of this study was to determine the frequency of CYP3A5*3 polymorphism and its effect on the pharmacokinetics of tacrolimus in post-renal transplant patients at Mandalay General Hospital. Methods: Three different genotypes of CYP3A5 were determined by polymerase chain reaction-restriction fragment length polymorphism in 54 post-renal transplant recipients. Tacrolimus trough concentrations (Ctrough) were measured by enzyme multiplied immunoassay technique following method validation. The apparent clearance (CL/F) was calculated from measured Ctrough. Results: The frequency of CYP3A5*1 allele was 0.24 and that of CYP3A5*3 allele was 0.76 in the study sample. There were a total of 33 CYP3A5 non-expressors (patients with CYP3A5*3/*3 genotype) and 21 CYP3A5 expressors (patients with CYP3A5*1/*1 or CYP3A5*1/*3 genotype), respectively. CL/F was significantly lower in the non-expressor group than in the expressor group (mean±standard deviation, 12.53±5.28 vs. 21.22±5.95 L/hr; P<0.001). The mean Ctrough and concentration dose ratio (C/D) for tacrolimus in CYP3A5 non-expressors were significantly higher than those in CYP3A5 expressors (Ctrough, 7.14±2.56 vs. 5.92±1.76 ng/mL; C/D, 6.92±4.11 vs. 2.89±1.85 ng/mL/mg), respectively (P<0.05). Conclusions: In this study, 76% of the Myanmar renal transplant recipients carried the CYP3A5*3 allele that was associated with lower functional activity of the CYP3A5 enzyme a lower CL/F of tacrolimus in these Thus, CYP3A5 polymorphism influences the pharmacokinetics of tacrolimus, which may affect the pharmacological response to tacrolimus.
