Research ArticleOpen accessIn the abstractCOLORIMETRIC DETERMINATION OF CEFQUINOME SULPHATE IN BULK AND DOSAGE FORM USING AMMONIUM MOLYBDATEShaza Wageialla Shantier, Elrasheed Ahmed GadkariemThis study was designed to develop two colorimetric methods for the determination of Cefquinome Sulphate (CS) in bulk and dosage forms using two different concentrations of molybdenum solution. The developed methods were based on the oxidation of CS with 2% ammonium molybdate, in the presence of sulphuric acid, producing a green colored product with λmax at 409 nm (Method I) … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 20 Dec 2013 · 7,051 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffectiveness of Photocatalytic Decolourization of Reactive Red 120 Dye in Textile Effluent Using UV/H2O2Rishi Ananthashankar, Abdel GhalyThe effectiveness of Advanced Oxidation Process (AOP) for degradation of reactive red 120 dye in aqueous solutions was tested in this present study. Ten different concentrations of the reactive red 120 dye were exposed to UV alone and a combination of UV with two different concentrations (10 ml/L and 20 ml/L) of H2O2 for 10 different retention times at the … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,408 accessesView PDFCite
Research ArticleOpen accessIn the abstractCiprofloxacin Induced Chondrotoxicity and TendinopathyElias Adikwu, Nelson BrambaifaCiprofloxacin is one of the fluoroquinolones with a wide clinical acceptability. Rescently there are increasing reports on Ciprofloxacin induce Chondrotoxicity and Tendinopathy in Animal experiment and clinical experience which is of great clinical concern. A comprehensive survey and review of literaure on reported ciprofloxacin induced Chondrotoxicity and Tendinopathy in Humans and Animals was performed. It was observd that ciprofloxacin is … …American Journal of Pharmacology and Toxicology, Vol. 7, Issue 3 · 19 Oct 2012 · 10,414 accessesView PDFCite
Research ArticleOpen accessIn the abstractDihydrobiopterin (BH2): Key Determinant in Influencing Arginine Mediated Endothelial Tolerance and DysfunctionSrinidi Mohan, Harsh Patel, Jorge Bolinaga et al.The redox-sensitive tetrahydrobiopterin (BH4) is an essential cofactor that is required by endothelial Nitric Oxide Synthase (eNOS) for L-arginine (ARG) mediated Nitric Oxide (NO) generation. Oxidation of BH4 causes cofactor insufficiency and uncoupling of eNOS, resulting in product switching from NO to O2⋅– production. Here we tested the hypothesis that eNOS uncoupling is not simply a consequence of BH4 insufficiency, … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 8,348 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental and Skeletal Kinetic Model Study of Compressed Natural Gas Fueled Homogeneous Charge Compression Ignition EngineP. M. Diaz, B. Durga Prasad, D.S. Manoj Abraham, K. PalaniKumarProblem statement: In homogeneous charge compression ignition engines fuel oxidation chemistry determines the auto-ignition timing, heat release, reaction intermediates and the ultimate products of combustion. To shorten development time and to understand combustion processes, the use of simulation is increasing. Approach: A model that correctly simulates fuel oxidation at these conditions would be a useful design tool. Detailed models of … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 22 Mar 2012 · 7,255 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Cycle Duration and Phasing on Thermomechanical Fatigue of Dog-Bone Specimens Made form SteelAchegaf Zineb, Khamlichi Abdellatif, Francisco Mata CabreraProblem statement: Lifetime of standard dog-bone specimens made form steel as affected by phasing between thermal cycles and strains cycles and by cycle duration in thermomechanical fatigue is assessed under various conditions of loading. Approach: The methodology used was based on finite element post-processing analysis by specialized fatigue software package that takes into account coupling of damage from three primary … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 7,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vitro Interaction of 5-Hydroxytrptamine with Cytosolic Molybdenum Hydroxylases as a Potential Inhibitor for Initial Rates ActivitiesAbdullah M. Al-Mohizea, Abd El-Galil E. Amr, Mohamed A. Al-OmarProblem statement: The role of 5-HT has been investigated in many behavioral activities. Thus, studies using raphe lesion showed that 5-HT is involved in sleep, general activity levels, habituation, aggression, pain sensitivity and morphine analgesia, avoidance behavior, self-stimulation and water consumption. Approach: The metabolic interaction between serotonin (5- hydroxytrptamine) and indole-3-aldehyde and xanthine via aldehyde oxidase (EC 1.2.3.1) and xanthine … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 7,026 accessesView PDFCite
Research ArticleOpen accessIn the abstractFish Spoilage Mechanisms and Preservation Techniques: ReviewA. E. Ghaly, D. Dave, S. Budge, M. S. BrooksProblem statement: Spoilage of food products is due to chemical, enzymatic or microbial activities One-fourth of the world’s food supply and 30% of landed fish are lost through microbial activity alone. With the ever growing world population and the need to store and transport the food from one place to another where it is needed, food preservation becomes necessary in … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 59,795 accessesView PDFCite
