Immunobioinformatics of Rabies Virus in Various Countries of Asia : Glycoprotein Gene

he purpose of this study was to analyze the genomic information of the glycoprotein gene of rabies virus (RABV) in several countries of Asia. The genomics information of vaccine virus strain and some local isolates were retrieved from GeneBank® (National Center for Biotechnology Information, USA). Ten genomics informations are consist of ERA vaccine virus, two viruses from Indonesia, a virus from Myanmar, India, Nepal, South Korea, Japan, Sri Lanka, and Iran. This bioinformatics process the ten genomics data in order to find pattern in 1,575 bp of glycoprotein gene of RABV. In conclusion, this study have revealed the data of homology, B-cell epitope prediction, genetic distance, and molecular phylogenic analysis of RABV in various countries of Asia. We indicated that the glycoprotein, the immunogenic surface protein of RABV, has important part for vaccine design Keywords: Bioinformatics Lyssavirus glycoprotein rabies vaccin

Phaleria macrocarpa (Scheff.) Boerl. Pulp Extract Increases the Sperm Characteristics in Rattus norvegicus

Herbal remedy is a type of alternative medicine that originates from plants and have been around for centuries. This study to analyze Phaleria macrocarpa L. pulp extract (PMPE) on male fertility by assesing its effect on sperm characteristic including sperm count, motility, viability and membrane integrity.Twenty four males adult of Rattus norvegicus were seperated into four groups. The treatment of three groups were done orally, once a day with 0.25 ml supplemented for four weeks either with PMPE at doses 7.5 mg/kg (P1), 15 mg/kg (P2), 30 mg/kg (P4) and CMCNa 0.5% (P0). PMPE significantly increases the percentage of sperm characteristic. Keywords: Phaleria macrocarpa, motility, viability, membrane integrit

Molecular identification of trichoderma isolates from sugarcane bagasse based on Internal Transcribed Spacer (ITS) rDNA

This study aimed to identify Trichoderma from sugarcane bagasse based on iinternal transcribed spacer (ITS) rDNA. The sample used was pure isolate of Trichoderma from sugarcane bagasse. DNA samples were isolated using the modified CTAB method. DNA was amplified using the primers ITS1 and ITS4. Interestingly, the results showed that Trichoderma genomic DNA has a concentration of 92.56 mg with a purity of 1.91. The amplicon of Trichoderma DNA is about 600 bp, whereas phylogenetic analysis shows that the sample of Trichoderma from sugarcane bagasse is one group with Trichoderma harzianum, Trichoderma piluliferum, Trichoderma sp. SQR339, Hypocrea nigricans, and Trichoderma sp. NFML CH12 BB. 15, Trichoderma aureoviride, Hypocrea lixii, and Trichoderma BAB-4585

Biological Activity of Kencur (Kaempferia Galanga L.) Against SARS-CoV-2 Main Protease: in Silico Study

COVID-19 is a syndrome affecting pulmonary function but rather in serious conditions leads to death. Kencur (Kaempferia galanga L.) is a type of rhizome plant in Indonesia that is used as an herbal medicine called Jamu because it is believed to be able to cure various types of diseases. One of which is for anti-virus. The goal of this study was to see how effective the compounds in kencur are against COVID-19 with a molecular docking strategy. Kencur biological activities were obtained from the library and the design of the Acute Respiratory Syndrome Main protease (Mpro) has been gained from the protein data bank website. In addition, the biological activities in kencur were examined utilizing Lipinski's five-point concept was used to evaluate their substance molecular characteristics. Molecular docking analysis was performed with the PyRx Virtual Screening Tool software. The PyRx program was used for molecular docking simulation. While, the Discovery Studio Visualizer program was used to visualize the interaction between SARS-CoV-2 (Mpro) and the pharmacologically active metabolites in kencur. The docking evaluation on three antiviral substances revealed that Quercetin had the lowest binding energy when bound with Mpro and thus had the greatest potential as a viral inhibitor
