Research ArticleOpen accessIn the abstractPterostilbene Enhanced Anti-Methicillin Resistant Staphylococcus aureus (MRSA) Activity of OxacillinSiti Fairuz Ishak, Ahmad Rohi Ghazali, Noraziah Mohamad Zin, Dayang Fredalina BasriMethicillin-resistant Staphylococcus aureus (MRSA) is a deadly pathogen that initially was limited to hospital and healthcare facilities but has gradually became a growing problem in healthy children and adults. Pterostilbene belongs to the phenylpropanoid phytoalexin which is involved in plant response to various pathogen and herbivores attack. The aim of this study is to evaluate the anti-MRSA action of pterostilbene … …American Journal of Infectious Diseases, Vol. 12, Issue 1 · 13 Jan 2016 · 8,339 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatus of Heavy Metals in Water and Sediment of the Meghna River, BangladeshMahmud Hassan, Mirza A.T.M. Tanvir Rahman, Badhan Saha, Abdul Kadir Ibne KamalThe pollution of river water and sediments by heavy metals has assumed serious problems due to their toxicity and accumulative behavior. The present study has been undertaken to assess the levels of heavy metals and the extent of pollution in the surface water and sediments from the Meghna river. Water and sediment samples were collected by the Standard Methods and, … …American Journal of Environmental Sciences, Vol. 11, Issue 6 · 24 Nov 2015 · 12,843 accessesView PDFCite

The study was extended to identify the trace metal contamination in the water and sediment samples collected along the shores of Lambapur and Peddagattu the tribal villages in India using an … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 26 Mar 2014 · 7,604 accessesView PDFCite
Research ArticleOpen accessIn the abstractSYNERGY OF A NOVEL ANTIBIOTIC ADJUVANT ENTITY AGAINST MULTI DRUG RESISTANT ENTEROBACTERIACEAEManu Chaudhary, Anurag PayasiIn the present investigation, we investigated the in vitro interaction of ceftriaxone plus sulbactam with disodium edetate, a Non Antibiotic Adjuvant (NAA) against selected clinical isolates and in vitro susceptibility studies were also performed. The isolates were tested against a range of ratios of ceftriaxone and sulbactam using a microdilution checkerboard method. Having determined the appropriate ratios of ceftriaxone plus … …American Journal of Infectious Diseases, Vol. 9, Issue 3 · 1 Nov 2013 · 7,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolygalacturonase and Pectin Methylesterase Activities of CaCl2 Treated Red-Fleshed Dragon Fruit (Hylocereus polyrhizus) Harvested at Different MaturityY. B. Awang, S. H. Chuni, M. T.M. Mohamed et al.Fruits harvested at different maturity possess different biochemical constituents and physiological properties that make the fruits may react somewhat differently to the postharvest treatment. A study to examine the activity of Polygalacturonase (PG) and Pectin Methylesterase (PME) enzymes during storage in dragon fruit (Hylocereus polyrhizus) harvested at 28 days (Index 3) and 34 days (Index 5) after anthesis and postharvest … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 23 Jul 2013 · 8,436 accessesView PDFCite
Research ArticleOpen accessIn the abstractX-RAYS LUMINESCENCE, OPTICAL AND PHYSICAL STUDIES OF BI2O3-B2O3-SM2O3 GLASSES SYSTEMS. Rakpanich, J. Kaewkhao, N. Srisittipokakun et al.Sm3+-doped bismuth borate glasses of the composition (50-x) SiO2: 50B2O3: xSm2O3 (where x = 0.00, 0.50, 1.00, 1.50, 2.00 and 2.50 mol%) have been synthesized by conventional melt quenching technique. In order to understand the role of Sm2O3 in bismuth borate glasses, the density, molar volume, refractive index and optical absorption were investigated. The results show that density, molar volume … …Physics International, Vol. 4, Issue 1 · 18 Jul 2013 · 7,466 accessesView PDFCite
Research ArticleOpen accessIn the abstractEr3+-Doped Soda-Lime Silicate Glass: Artificial Pink GemstonePichet Limsuwan, Kheamrutai Thamaphat, Jakrapong Kaewkhao, Weeranut KaewwisetEr3+-doped soda-lime silicate glasses of the composition (in mol%) (65-x)SiO2:25Na2O:10CaO:xEr2O3 (where x = 0, 1, 2, 3, 4 and 5) were fabricated by conventional melt quenching technique. The physical and optical properties were measured and investigated. The erbium oxide enters the glass network as a modifier by occupying the interstitial space in the network and generating the NBOs to the … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 29 Aug 2012 · 7,404 accessesView PDFCite
