Research ArticleOpen accessIn the abstractA HIGH B1 FIELD HOMOGENEITY GENERATION USING FREE ELEMENT ELLIPTICAL FOUR-COIL SYSTEMSidi M. Ahmed Ghaly, Sulaiman S. Al-SowayanDesign and testing of a prototype probe with high B1 magnetic field homogeneity that can be used for MRI is presented. It consists of four coaxial separately tuned rings of wire in a symmetric arrangement on an ellipsoidal surface. Compared to Helmholtz pair, which presents 2nd-order homogeneity, an improvement in field homogeneity is achieved, while preserving the simplicity of implementation. … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 28 Jan 2014 · 7,025 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification 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 PDFCite
Research ArticleOpen accessIn the abstractBio-Guided Study on Melastoma malabathricum Linn Leaves and Elucidation of its Biological ActivitiesMourouge Saadi Alwash, Nazlina Ibrahim, Wan Yaacob AhmadThe present study aimed to isolate and identify constituents with antibacterial activity from the Methanol extract of Melastoma malabathricum leaves (MMML) through bioassay guided fractionation. Furthermore, the study scoped to evaluate the cytotoxic effects of M. malabathricum leaves fractions for possible protective effect of antoxidative constituents present in the fractions. The MMML extract was fractionated by Vacuum Liquid Chromatography (VLC) … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 9,519 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Characterization of Inflammatory and Structural Markers within the Rumen Epithelium During Grain-Induced Ruminal Acidosis in Lactating Dairy CattleL. Dionissopoulos, M. A. Steele, O. AlZahal et al.The objective of this study was to characterize the mRNA and protein expression of inflammatory and structural genes in the rumen epithelium during grain-induced ruminal acidosis in lactating dairy cattle. A total of 16 rumen-fistulated, lactating Holstein dairy cattle (618±35 kg of body weight, 221±32 days in milk) were used in a randomized complete block design study. All cattle were … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 3 · 19 Sep 2012 · 8,038 accessesView PDFCite
Research ArticleOpen accessIn the abstractZinc Phosphide Induced DNA Damage in the Blood Cells of Gallus sp. using Comet DNA AssayK. A. Muid, R. M. Shahjahan, R. Begum, R. A. BegumProblem statement: The comet DNA assay is considered a suitable and rapid test for DNA-damaging potential in environmental and biomonitoring studies. Approach: During the study comets were analyzed as a measure of DNA damage to quantify the damage in the blood cells of fowls (Gallus sp.) after exposure to Zinc Phosphide (Zn3P2). Here the potential for DNA strand breaks by … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 3 Mar 2012 · 8,957 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Radioactive Impact Associated to Uranium ProductionFernando P. CarvalhoProblem statement: One century of uranium mining in Europe and North-America created a legacy of ore mining and milling sites needing rehabilitation for environmental and human safety. In the last decades developments of uranium mining displaced the core of this activity to Australia, Canada and African countries. In the coming years, uranium mining is expected to grow further, in those … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 14 Jan 2012 · 8,257 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural and Evolutionary Analysis of PARPs in D. discoideumA. Mehadvi Kawal, Hina A. Mir, Chethan Kumar Ramniklal et al.Problem statement: Dictyostelium discoideum, a unicellular eukaryote, exhibits multicellularity upon nutrient starvation, making it a better model for developmental studies and for the study of various signal transduction pathways. The most felicitous point of interest is that many of its genes show high degree of similarity to vertebrate genes. Poly (ADP-ribose) polymerase (PARP), a ubiquitous and abundant nuclear protein, has … …American Journal of Infectious Diseases, Vol. 7, Issue 3 · 3 Nov 2011 · 7,855 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntibacterial Activity of β-Cyclodextrin and 2-Hydroxypropyl-β-Cyclodextrin Trimethoprim ComplexesHsien-Kuo Sun, Madhumathi Seshadri, Scott Lingard et al.Problem statement: Cyclodextrin complexation has previously been shown to improve the solubility and dissolution properties of trimethoprim; however, no report provides an account of the effect cyclodextrin complexation has on the antibacterial activity of this agent. Approach: β-cyclodextrin and 2-hydroxypropyl β-cyclodextrin inclusion complexes of trimethoprim were prepared and confirmed by differential scanning calorimetry and proton nuclear magnetic resonance. The in-vitro … …Current Research in Microbiology, Vol. 2, Issue 1 · 26 Oct 2011 · 14,806 accessesView PDFCite
Research ArticleOpen accessIn the abstractVertical Profile of C, N, P, K and Radionuclides in Soil Collected from Highland Tea Plantation AreasZaini Hamzah, Seh Datul Riduan, Ahmad SaatProblem statement: Cameron Highlands is a well known agricultural area in Peninsular Malaysia. Long term usage of fertilizer has caused accumulation of major elemental component in the soil. This accumulation will cause enrichment of the nutrient in the catchment located at downstream of the river through runoff. Approach: Two tea plantations on the upstream with hilly condition plantation were selected … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 11 Oct 2011 · 7,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractPalmitate-Induced Translocation of Caveolin-3 and Endothelial Nitric Oxide Synthase in CardiomyocytesCatherine J. Knowles, Megan Dionne, Martina Cebova, Ilka M. PinzProblem statement: Palmitate is a known cardiac lipotoxin that blunts cardiomyocyte contractile function and induces apoptosis, likely via accumulation of the lipotoxic ceramide. Ceramide is a sphingolipid and localizes to caveolae, which are lined in the inner membrane leaflet by caveolin proteins. In this study, we investigated the effects of palmitate on caveolin proteins and on endothelial Nitric Oxide Synthase … …OnLine Journal of Biological Sciences, Vol. 11, Issue 2 · 27 Aug 2011 · 7,897 accessesView PDFCite
