Research ArticleOpen accessIn the abstractDetermination of Trivalent Aluminum and Divalent Zinc in Drinking Waters by Differential Pulse Stripping VoltammetryAhmed HassanA Sensitive and precise differential- pulse stripping voltammetric method at static mercury dropping electrode (SMDE) has been applied to measure zinc(II) by anodic stripping at pH~¼4 and aluminum(III) by adsorptive cathodic stripping mode in presence of 1&Cross10-3M N,N` -bis-2-hydroxyethyl-2-amino-ethane sulphonic acid (BES) buffer at pH~7.1 and 2⨯10-5 M of alizarin red S as a ligand in drinking water samples purchased … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,588 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Study of Morphological Structure, Phase Structure and Molecular Structure of Collagen-PEO 600K Blends for Tissue Engineering ApplicationN. F. Mohd Nasir, M. G. Raha, N. A. Kadri et al.A new material which is collagen/ poly (ethylene oxide) (PEO) blend was developed to determine its possibility as a promising material for tissue scaffold. PEO with average molecular weight of 600,000 and collagen originated from calf skin were dispersed in 0.1 M acetic acid to prepare a concentration of 1 wt% for PEO and 0.15 wt% for collagen. The collagen-PEO600K … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 7,426 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Application of Electrochemical Impedance Techniques in Analyzing the AC Response of Some Two-electron Transfer Dye SystemsFarouk RashwanThe Electrochemical Impedance Spectroscopic techniques (EIS) were used to investigate the behavior of some dye compounds (quinoid systems) characterized with 2e-transfer processes. For this purpose, Alizarin Red S (ARS), Alizarin Cyanine (AC), Alizarin Viridin (AV) and carminic acid were chosen for the measurements. The EIS experiments were performed using a small AC amplitude (10 mV p-p) in addition to a … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 6,783 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBiochemical Composition and Nutraceutical Perspectives Red Sea SeaweedsEman A. AlwaleedSeaweeds are marketed as “nutraceuticals” owing to their highly bioactive ingredients as well as food supplements in order to relinquish physiological conditions and resist diseases. In the current study, the biochemical compositions (total protein, carbohydrate, lipid, fatty acids, amino acid, minerals and dietary fibers) of the seaweeds Caulerpa racemosa, Digenea simplex, Sargassum polycystum and Cystoseria myrica were evaluated. Digenea simplex … …American Journal of Applied Sciences, Vol. 16, Issue 12 · 23 Jan 2020 · 7,606 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDetermination and Evaluation of Antioxidative Activity in Red Dragon Fruit (Hylocereus undatus) and Green Kiwi Fruit (Actinidia deliciosa)Normala Halimoon, Mardhiah Hayati Abdul HasanProblem statement: Dragon fruit or pitahaya (Hylocereus undatus), is believed to be a healthy source of vitamins, fiber and antioxidants, especially the red-fleshed varieties which contain lycopene. Approach:Compared to green kiwi fruit (Actinidia deliciosa), which already known contain high antioxidant activity. Results:The antioxidant capacity of Hylocereus undatus (H. undatus) and Actinidia deliciosa (A. deliciosa) in three different solvent extraction; ethanol, … …American Journal of Applied Sciences, Vol. 7, Issue 11 · 8 Nov 2010 · 9,160 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIn Vivo Neutralization of Naja nigricollis Venom by Uvaria chamaeOmale James, Ebiloma Unekwuojo Godwin, Idoko Grace OtiniUvaria chamae is a well known medicinal plant in Nigerian traditional medicine for the management of many diseases, but investigations concerning its pharmacological characteristics are rare. In this study, we evaluate its venom neutralizing properties against Naja nigricollis venom in rats. Freshly collected Uvaria chamae leaves were air dried, powdered and extracted in methanol. To study the antivenom properties, albino … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 8,424 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordProphylactic Effects of Melatonin on Sodium Valproate-Induced Neural Tube Defects and Skeletal Malformations in Rat EmbryosOmolbanin Rahgazar, Reza Ranjbar, Hossien Najafzadeh Varzi, Mahmood Khaksary MahabadyProblem statement: Some reports showed the teratogenic effects of sodium valproate can be prevented by application of antioxidant drugs and stimulation of the maternal immune system. Therefore, in this study, the prophylactic effect of melatonin on teratogenic effects of sodium valproate was compared. Approach: This study was performed on 31 pregnant rats that were divided into five groups. Control group … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,286 accessesView PDFCite
