Review ArticleOpen accessIn the author namesCurrent Laboratory Biosecurity for Handling Pathogenic VirusesI Made Artika, Chairin Nisa Ma’roefThe recent emergence of lethal viruses such as Ebola raises some concern about the possibility of the viruses being used as biological weapons. The application of pathogenic viruses as biothreat agents in the past is well documented. Although their use in warfare is currently prohibited by the Biological and Toxin Weapon Convention, their potential use in bioterrorism is a global … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 6 Apr 2018 · 10,627 accessesView PDF Cite

Research ArticleOpen accessIn the author namesAntibacterial Activity of Skin Secretion of Bleeding Toad Leptophryne cruentata and Javan Tree Frog Rhacophorus margaritiferI Made Artika, Sabrina Pinontoan, Mirza Dikari KusriniBacterial resistance towards antibiotics has increased morbidity, mortality and health-care costs. Therefore, it is important to search for new types of antibacterial agents. This study was aimed to test antibacterial activity of epinephrine-stimulated skin secretions derived from two species of Anura endemic in Indonesia, the bleeding toad Leptophryne cruentata and the javan tree frog Rhacophorus margaritifer. The filter-sterilized skin secretions … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 3 · 7 Jul 2015 · 7,628 accessesView PDF Cite

Research ArticleOpen accessIn the author namesAntifungal Activity of Skin Secretion of Bleeding Toad Leptophryne Cruentata and Javan Tree Frog Rhacophorus MargaritiferI. Made Artika, Sabrina Pinontoan, Mirza Dikari KusriniAmphibian skin has been the source of a wide variety of biologically active compounds. This study was aimed to determine antifungal activity of skin secretion of two species of anurans endemic in Indonesia, the bleeding toad Leptophryne cruentata and the javan tree frog Rhacophorus margaritifer. We collected 7 adults of L. cruentata and 10 adults of R. margaritifer from the … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 16 Jan 2015 · 8,130 accessesView PDF Cite

Research ArticleOpen accessIn the author namesIdentification of Pseudozyma hubeiensis Y10BS025 as a Potent Producer of Glycolipid Biosurfactant Mannosylerythritol lipidsMartha Sari, Atit Kanti, I. Made Artika, Wien KusharyotoMannosylerythritol Lipids (MEL’s) are glycolipid biosurfactants that contain 4-O-β-D-mannopyranosyl-meso-erythritol as a hydrophilic moiety and fatty acids as a hydrophobic moiety. MEL’s are abundantly produced by several kinds of microorganism and are one of the most promising biosurfactants currently known. The search for a novel endogenous producer of MEL’s was undertaken based on the available collection of the yeast strains from … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 8,103 accessesView PDF Cite

Research ArticleOpen accessIn the author namesMolecular Cloning and Heterologous Expression of Human Interferon Alpha2b GeneI. Made Artika, Yemima Budirahardja, Anna Lucia EkowatiHuman alpha Interferons (hIFNα) have been shown to have antiviral, antiproliferative and immunomodulatory activities. The human interferon alpha2b (hIFNα2b), is one of the human interferon alpha2 sub variants, naturally synthesized as a polypeptide of 188 amino acid residues, the first 23 residues of which represents a signal peptide. In the present study, the hIFNα2b gene was expressed after being fused … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,840 accessesView PDF Cite
