Research ArticleOpen accessIn the abstractIn 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 · 8,421 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeciation and Availability of Cr, Ni and Co IN Serpentine Soils of Ranau, SabahMahsa Tashakor, Wan Zuhairi Wan Yaacob, Hamzah MohamadProblem statement: Serpentine soils are known as a geogenic source of heavy metal pollution because they are anomalously rich in chromium, nickel and cobalt. Approach: However, only that portion of these metals which is available in the ecosystem and incorporates in the bio-transformation processes, is dangerous for the environment. Availability of Cr, Ni and Co depends on their speciation into … …Current Research in Geoscience, Vol. 2, Issue 1 · 20 Mar 2013 · 13,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptical Investigation and Electronic Polarizability of Nd3+ Doped Soda-Lime-Silicate GlassesP. Chimalawong, J. Kaewkhao, P. LimsuwanProblem statement: This study researched on different physical and optical properties of Nd3+ doped soda-lime-silicate glass. The glasses containing Nd3+ in (65-x)SiO2: 25Na2O: 10CaO: xNd2O3 (where x = 0.0-5.0 mol%) had been prepared by melt-quenching method. The density and molar volume increase with increasing of Nd2O3 concentration due to increasing of Non Bridging Oxygen (NBOs) in glass matrix. The optical … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,149 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotocatalytic Activity and Antibacterial Behavior of Fe3+-Doped TiO2/SnO2 NanoparticlesLek Sikong, Budsabakorn Kongreong, Duangporn Kantachote, Weerawan SutthisripokProblem statement: Since bacteria mainly causes damage on fresh vegetables and fruits during transportation to market, anti-bacterial TiO2 photocatalyst was applied for their packaging films. However, it has been known that pure TiO2 exhibits low photocatalytic property due to rapid recombination of photo-activated electrons and holes. Doping with metal or metal oxide shows the improvement of photocatalytic activity and disinfection … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 15,233 accessesView PDFCite
Research ArticleOpen accessIn the abstractFactors Affecting the Synthesis and Formation of Single-Phase Barium Hexaferrite by a Technique of Oxalate PrecursorQ. MohsenProblem statement: Barium hexaferrite (BaFe12O19), is of great importance as permanent magnets, particularly for magnetic recording as well as in microwave devices. Approach: The aim of this study was to synthesize Stoichiometric and single-phase barium hexaferrite through a technique of oxalate precursor. Effects of different Fe3+/Ba2+ mole ratio and annealing temperature on the particle size, microstructure and magnetic properties of … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractArsenic and Antimony Content in Soil and Plants from Baia Mare Area, RomaniaGabriela Oprea, Angela Michnea, Cristina Mihali et al.Problem statement: The objective of this research was to evaluate the degree of soil contamination with arsenic and antimony in Baia Mare, a nonferrous mining and metallurgical center located in the North West region of Romania. The soil in the area is affected by the emissions of powders containing metals from metallurgical factories. Previous studies indicated the soil contamination with … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnti-Ulcer (Ulcer-Preventive) Activity of Ficus arnottiana Miq. (Moraceae) Leaf Methanolic ExtractMarslin Gregory, K. P. Vithalrao, G. Franklin, V. KalaichelavanProblem statement: In spite of being one of the well-known medicinal plants used in Indian traditional medicine to treat several ailments, studies pertaining to the pharmacological properties of Ficus arnottiana are very scarce. We studied the anti-ulcer activity and acute toxicity of Ficus arnottiana leaf methanolic extract for the first time. Approach: Freshly collected F. arnottiana leaves were dried, powdered … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 9,329 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlasma Bilirubinaemia; A Physiologic Index for Monitoring Cellular Effects of Amalar, Chloroquine, Cotecxin and FansidarE. O. Jimmy, I. F. UsohProblem statement: Antimalaria drugs are highly consumed in Africa due to increase prevalent of malaria attacks. Though the disease is often cured with some antimalarials the physiologic effects of such drugs may not be considered in pharmacologic preparations and in prescriptions. Such non consideration is likely to result in serious health problems which may outweigh the effects of malaria disease … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 7,541 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreliminary Tests Concerning Zero-Valent Iron Efficiency in Inorganic Pollutants RemediationSilvia Fiore, Maria Chiara ZanettiProblem statement: This study was aimed to a preliminary evaluation of the applicability of granular Zero-Valent Iron (ZVI) to the on site remediation of groundwater polluted by inorganic contaminants by means of a Permeable Reactive Barrier (PRB).

Research ArticleOpen accessIn the abstractReducing Ammonia Loss from Urea by Mixing with Humic and Fulvic Acids Isolated from CoalAmeera Abdul Reeza, Osumanu Haruna Ahmed, Nik Muhamad Nik Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization is a major pathway for nitrogen loss from surface applied urea. While all top-dressed ammonia and ammonium based N fertilizers can volatilize, the potential loss is greatest with urea and fluids containing urea. As much as 20-50% of N applied to soils is lost through volatilization alone. Thus, the objective of this laboratory study was to … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 10,897 accessesView PDFCite
