Research ArticleOpen accessIn the author namesIN SILICO DESIGN OF THE M2 PROTON CHANNEL INHIBITORS OF H1N1 VIRUSUsman Sumo Friend Tambunan, Mochamad Reza Rahdiansyah, Arli Aditya ParikesitM2 proton channel of H1N1 Influenza A virus is the target protein anti-flu drugs amantadine and rimantadine. However, the two once powerful adamantane-based drugs lost their 90% bioactivity because of mutations of virus in recent twenty years. The resistance of influenza A virus to amantadine need to develop more effective adamantane-based drugs. Several research by molecular docking method have been … …OnLine Journal of Biological Sciences, Vol. 13, Issue 1 · 5 Jan 2013 · 8,002 accessesView PDFCite
Research ArticleOpen accessIn the author namesInformation and Communication Technology Innovation for Construction Site ManagementNuruddeen Usman, Ilias SaidProblem statement: The industrialization of the world from whole to site as a result of technological innovation made many industries adopting Information and Communication Technology (ICT) for processing of all their activities from inception to completion, especially in the developed nations. But, the developing nations appear to make sluggish progress towards ICT adoption due to apprehensiveness that their fraudulent activities … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 28 Jun 2012 · 7,263 accessesView PDFCite
Research ArticleOpen accessIn the author namesMolecular Dynamics Simulation of DENV RNA-Dependent RNA-Polymerase with Potential Inhibitor of Disulfide Cyclic PeptideUsman Sumo Friend Tambunan, Raima Syahidah Noors, Arli Aditya Parikesit et al.Problem statement: Our researches have proposed two ligands of disulfide cyclic polypeptide, which are CDEEC and CDGSC as potential inhibitor of DENV RNA-dependent RNApolymerase by molecular docking. Approach: Methodological approach was conducted to determine the best ligand to act as inhibitor. Molecular docking simulation was conducted without a solvent in which enzyme was made rigid and ligand was left free … …OnLine Journal of Biological Sciences, Vol. 11, Issue 2 · 30 Sep 2011 · 8,446 accessesView PDFCite
Research ArticleOpen accessIn the author namesBioactive Compounds Screening from Zingiberaceae Family as Influenza A/Swine Flu Virus Neuraminidase Inhibitor through Docking ApproachUsman Sumo Friend Tambunan, Fadilah, Arli Aditya ParikesitProblem statement: Influenza A/H1N1 is a disease caused by infection of influenza a virus subtype H1N1. It is a major health problem in tropical and subtropical countries. This virus constantly mutates and consequently will be developed into new drug-resistant strains. Approach: In this research, we have conducted docking study to screen bioactive compounds from Zingiberaceae family, which has a role … …OnLine Journal of Biological Sciences, Vol. 10, Issue 4 · 31 Dec 2010 · 8,623 accessesView PDFCite
Research ArticleOpen accessIn the author namesIn Silico Analysis of Envelope Dengue Virus-2 and Envelope Dengue Virus-3 Protein as the Backbone of Dengue Virus Tetravalent Vaccine by Using Homology Modeling MethodUsman Sumo Friend Tambunan, Arli Aditya Parikesit, Hendra et al.Problem statement: Dengue fever, which was caused by Dengue virus infection, had became a major public health problem in the tropic and subtropical countries. Dengue virus (DENV) had four serotypes (DENV-1, DENV-2, DENV-3 and DENV-4), based on their immunogenic in the human body. Preventive measure will be necessary to decrease the prevalence of dengue fever, by developing modern vaccine. Approach: … …OnLine Journal of Biological Sciences, Vol. 9, Issue 1 · 3 Sep 2010 · 9,268 accessesView PDFCite
Research ArticleOpen accessIn the author namesDesign and Evaluation of Three Pair Primers for Exon 1 Amplification of Hyaluroglucosaminidase-1 GeneUsman Sumo Friend Tambunan, Sylvia Sugito, Arli Aditya ParikesitProblem statement: Hyaluronidase is an enzyme which catalyze hydrolysis of Hyaluronan (HA). Hyaluronan is important in cell migration during embryonic development, cellular proliferation and differentiation and has a structural role in connective tissues. Hyaluronidase deficiency is correlated with mucopolysaccharidosis IX. In human, hyaluronidase is encoded by HYAL1 gene. The mutation study of HYAL1 gene was carried out by many researchers, … …OnLine Journal of Biological Sciences, Vol. 10, Issue 2 · 16 Jun 2010 · 8,711 accessesView PDFCite
Research ArticleOpen accessIn the author namesWireless Phones Electromagnetic Field Radiation Exposure AssessmentA. D. Usman, W.F. Wan Ahmad, M.Z.A. Ab Kadir, M. MokhtarProblem statement: Inadequate knowledge of electromagnetic field emitted by mobile phones and increased usage at close proximity, created a lot of skepticism and speculations among end users on its safety or otherwise. Approach: In this study, near field electromagnetic field radiation measurements were conducted on different brand of mobile phones in active mode using a tri-axis isotropic probe and electric … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,726 accessesView PDFCite
