Research ArticleOpen accessIn the abstractDetermination of Lead in Human Teeth by Hydride Generation Atomic Absorption SpectrometryHassan T. AbdulsahibProblem statement: The determination of lead in human teeth at concentration levels of μg/ml is proposed using Hydride Generation Atomic Absorption Spectrometry (HG-AAS). To do this, 2% (wv) lanthanum chloride solution was employed as matrix modifying reagent to increase sensitivity and remove matrix interferences. Approach: About 100 μL of sample and 100 μL of 3.0% (m/v) NaBH4 are simultaneously injected … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 31 Oct 2011 · 7,136 accessesView PDFCite
Research ArticleOpen accessIn the abstractResistance to Citrus Canker in Key/Mexican Lime Induced by β-Aminobutyric Acid and Green TeaB. Beheshti, G.R. Sharifi-Sirchi, M. Mansouri et al.Citrus bacterial canker, caused by Xanthomonas citri subsp. citri (Xcc), is a destructive disease. So far used chemicals to control this pathogen are either not effective or have harmful effects on the environment. To improve control of this disease, lime (Citrus aurantifolia) plants inoculated with Xcc were treated with β-Aminobutyric Acid (BABA), ascorbic acid (vitamin C), thiamin (vitamin B1), green … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,191 accessesView PDFCite

Approach: The study was conducted to investigated the silver nitrate (AgNO3) and sucrose at different concentration on rose cut flowers longevity, which determined on the basis of wilting, chlorophyll retention and carbohydrate degradation .The treatments were, water control, 20, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 10 Mar 2011 · 11,327 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Leakage Current to Predict Insulator Flashover Using Artificial Neural NetworkN. Narmadhai, A. Ebenezer JeyakumarProblem statement: The phenomenon of flashover in polluted insulators has been continued by the study of the characteristics of contaminating layers deposited on the surface of insulators in high voltage laboratories. In the literature, Experimental investigations have been carried out on a real insulator or a flat plate model of insulators under high voltage application. This study proposed the Equivalent … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,624 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 · 7,030 accessesView PDFCite
Research ArticleOpen accessIn the abstractHepatotoxicity Due to Histamine Trifluoro-Methyl Toluidide, Amthamine, R-(-)-α-Methyl Histamine and Clobenpropit (H1R-H4R-Agonists, Respectively) in Rabbit Experimental ModelTrivendra Tripathi, Aijaz Ahmed Khan, Mohammad Shahid et al.Problem statement: Since in vivo studies looking for toxicological impact of histamine receptors-agonists in experimental models are fragmentary, the present study was designed to delineate the histopathological and biochemical changes in livers of rabbits treated with histamine receptors (H1R-H4R)-agonists. Approach: The cohort comprised of six groups (Group I control and Group II-VI treated) containing five rabbits each. Control-group received vehicle … …Current Research in Medicine, Vol. 1, Issue 1 · 30 Jun 2010 · 8,905 accessesView PDFCite
