Research ArticleOpen accessIn the abstractA Morphological, Biochemical and Biological Studies of Halophilic Streptomyces sp. Isolated from Saltpan EnvironmentDeepika T. Lakshmipathy, Krishnan KannabiranProblem statement: Dermatophytes have developed resistance to the existing antifungal antibiotics. As a part of our continuous search we had isolated, identified and characterized actinomycetes from the halophilic environment having antagonistic activity against the dermatophytes namely Trichophyton, Microsporum and Epidermophyton. Approach: Actinomycetes were isolated from the soil sample collected from the Ennore saltpan region, Chennai, India and screened for antidermatophytic … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractStandardization of Metal-Based Herbal MedicinesArun Sudha, V. S. Murty, T. S. ChandraProblem statement: Standardization of herbal drugs is a burning topic in herbal drug industry today. Standardization is difficult because they are usually mixtures of many constituents and the active principle in most cases is unknown. However it is possible to generate a physico-chemical fingerprint for the standardization of these drugs with reference to authentic drugs, for monitoring variation between preparations … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,904 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrowth of Bone Marrow Derived Osteoblast-Like Cells into Coral Implant Scaffold: Preliminary Study on Malaysian CoralK. A. AL-SalihiProblem statement: Biomaterial fabrication in Malaysia started as a consequence of the demand for cheaper implant materials. Various biomaterials have been developed utilizing local resources like Malaysian coral. Locally processed Malaysian coral need to be complemented with proper evaluation and testing including toxicology, biocompatibility, mechanical properties, physicochemical characterization and in vivo testing. The present study was carried out to assess … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 3 · 30 Sep 2009 · 6,590 accessesView PDFCite
Research ArticleOpen accessIn the abstractScale Formation Due to Water Injection in Malaysian Sandstone CoresAmer Badr Bin Merdhah, Abu Azam Mohd YassinProblem statement: Scale deposition is one of the most serious oil field problems that inflict water injection systems primarily when two incompatible waters are involved. Approach: This study was conducted to investigate the permeability reduction caused by deposition of calcium, strontium and barium sulphates in sandstone cores from mixing of injected Malaysian sea waters (Angsi and Barton) and formation water … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of WO3 Nanoparticles Using Cetyl Trimethyl Ammonium Bromide Supermolecular TemplateNilofar Asim, S. Radiman, M. Ambar bin YarmoProblem statement: WO3 is one of the most interested metal oxides because of its application as catalysts, sensors, electrochromic devices, ceramic, solar cell, pigments and so on. More investigation is needed to find the good and low cost method for preparation of WO3 nanoparticles with uniform morphology and narrow distribution using a surfactant mediated method.
