Abstract

Objective: This study aims to map the distribution of the Aspartate 614 to Glycine (Asp614Gly) mutation in the spike protein of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) circulating in West Sumatra, to understand the extent of its spread within the local population. Methods: RNA samples were taken from 98 confirmed COVID-19 cases across various area in West Sumatra. Genetic amplification and next-generation sequencing (NGS) were performed to identify the presence of the Asp614Gly mutation. The frequency of mutations was analyzed using bioinformatics software. Results: Out of the 98 samples analyzed, approximately 97% exhibited the Asp614Gly mutation. The geographic distribution of this mutation showed significant variation among the districts of West Sumatra, with the highest prevalence in urban areas. Conclusion: These findings indicate that the Asp614Gly mutation is highly prevalent in West Sumatra. Associated with increased virus transmissibility, this mutation dominates the circulating virus strains in the region, highlighting the need for ongoing genetic surveillance to guide public health interventions and vaccination strategies.

Abstract

Sport has a crucial role in improving quality of life and health, but the environment including temperature and humidity can affect athletes' performance and health. This study focused on the impact of environmental temperature and humidity on hematocrit levels during exercise in Padang City. Using an ex-post facto design, the study involved 15 football players with pre-test and post-test hematocrit before and after a 10km jog. The results of the study are the body's hematocrit levels when exercising, evidenced by statistical analysis, namely: a). P value < 0.05, 0.034<0.05, b) Hematocrit increase that occurs with a difference of 1.25%, c) t calculate > t table which is 2.331 > 1.753 with α < 0.05.  The normality test shows normally distributed data, validating the results of the analysis. Increased hematocrit is related to oxygen demand and dehydration, which can be exacerbated by high temperatures and humidity. The research underscores the importance of a holistic understanding of the sports environment and the implementation of preventive measures, such as adequate fluid intake. Elevated hematocrit levels can be an indicator of dehydration risk, which can affect physical performance and heart health. Therefore, education on the body's adaptation to environmental changes and safe sports practices needs to be introduced to maintain the health and quality of life of people in environments with high temperatures and humidity. It can be concluded that there is a significant difference in the body's hematocrit levels when exercising with a P value of < 0.05.
Studi Molecular Docking dan Farmakoinformatika Senyawa Kurkumin dan Arturmeron pada Tumbuhan Kunyit (Curcuma Longa Linn.)

Abstract

Content Angiotensin Converting Enzyme (ACE) is an enzyme that is able to convert the peptide angiotensin 1 into angiotensin 2 which plays a role in the process that causes hypertension. Curcumin and artumeron are a group of chemical compounds that are widely contained in the turmeric plant (Curcuma Longa Linn.) which are reported to have the potential to inhibit ACE in vitro. The aim of this research is to predict the binding interactions of the curcumin and artumeron compound groups with the amino acids in ACE and using the native ligand captopril as the standard ligand. The method used was pharmacokinetic screening of active compounds in the curcumin and artumeron groups using ADMET predictions, Lipinski Rule of five and molecular docking simulations with the MOE program. Based on the results of screening and molecular docking simulations, it shows that the curcumin compound can bind to the ACE enzyme with a binding affinity of -6.032 kcal.mol-1 with a binding site with the amino acid Leu 342 better than captopril which has a binding affinity value of 4.427 kcal.mol-1 with binding sites with the amino acids Glu 342, Pro 344 and Thr 345. These results showed the curcumin compound potential used as a candidate for natural ingredients in antihypertensive treatment because according to in silico predictions it has abilities that are not much different from captopril. Keywords:          ACE, antihypertensive, in silico, Curcuma Longa Linn.   Abstrak Angiotensin Converting Enzyme (ACE) merupakan enzim yang mampu merubah peptida angiotensin 1 menjadi angiotensin 2 yang berperan dalam proses penyebab hipertensi. Senyawa kurkumin dan artumeron merupakan golnngan senyawa kimia yang banyak terkandung dalam tumbuhan Kunyit (Curcuma Longa Linn.) dilaporkan mempunyai potensi dalam menghambat ACE secara in vitro. Tujuan penelitian ini adalah untuk prediksi interaksi penambatan golongan senyawa kurkumin dan artumeron  dengan asam-asam amino pada ACE dan menggunakan ligan native kaptopril sebagai ligan standarnya. Metode yang digunakan berupa skrining senyawa aktif golongan kurkumin dan artumeron secara farmakokinetika dengan prediksi ADMET, Lipinski Rule of Five dan simulasi penambatan molekul dengan program MOE. Berdasarkan hasil skrining dan simulasi penambatan molekul menunjukkan bahwa senyawa curcumin dapat berikatan dengan enzim ACE dengan afinitas pengikatan sebesar -6,032 kcal.mol-1 dengan situs pengikatan dengan asam amino Leu 342 lebih baik dibandingkan dengan captopril yang mempunyai nilai afinitas pengikatan sebesar 4,427 kcal.mol-1 dengan situs pengikatan dengan asam amino Glu 342, Pro 344 dan Thr 345. Hasil ini menunjukkan senyawa curcumin  dapat dijadikan sebagai kandidat bahan alami dalam pengobatan antihipertensi karena secara prediksi in silico memiliki kemampuan yang tidak berbeda jauh dengan kaptopril.
