Research ArticleOpen accessIn the abstractInfluence of Oil Contamination on Geotechnical Properties of Basaltic Residual SoilZulfahmi Ali Rahman, Umar Hamzah, Mohd. Raihan Taha et al.Problem statement: Oil contamination due to accidental spillage or leakage brings hefty damage to the environments. It percolates steadily into subsurface environments and contaminates the soil and water system. Hydrocarbon contamination has not just affected the quality of the soil but will also alter the physical properties of oil-contaminated soil. Approach: This study presented the geotechnical properties of oil-contaminated soils … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 10,265 accessesView PDFCite

Approach: Tartrazine was administered to adult male mice in drinking water at doses of 0, 0.1, 1 … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 4 · 31 Dec 2009 · 10,408 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiochemical Changes in Wistar Rats on Oral Doses of Mistletoe (Loranthus micranthus)D. O. Edem, I. F. UsohProblem statement: To evaluate the effects of the water extract of the leaves of mistletoe (Loranthus micranthus) (traditionally used antidiabetic and antihypertensive) in male albino Wistar rats. Approach: The animals were divided into 4 groups (n = 6). Water extract of L. micranthus leaves was administered in graded doses of 0, 275, 551 and 827 mg kg-1 body weight (wt) … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 8,539 accessesView PDFCite
Research ArticleOpen accessIn the abstractSalicylic Acid Protects Nitrate Reductase Activity, Growth and Proline in Amaranth and Tomato Plants during Water DeficitC. E. Umebese, T. O. Olatimilehin, T. A. OgunsusiProblem statement: Seedlings of Amaranthus hybridus cv. NHAC-3 (large green, amaranth) and Lycopersicum esculentum cv. Roma (tomato) were subjected to 7 days water stress at Early Vegetative (EV), Late Vegetative (LV), Early Flowering (EF) and Late Flowering (LF) stages of growth to study the impact on leaf water potential (ψw), Nitrate Reductase Activity (NRA), growth (plant height, shoot and root … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,565 accessesView PDFCite
Research ArticleOpen accessIn the abstractUS Foreign Policy and Aid to the Peace CorpsDonald D.A. SchaeferProblem statement: This study examined foreign aid as administered by the US Agency for International Development (USAID) through four presidencies, beginning with the Reagan era. Aid dispensed to the Peace Corps for humanitarian purposes was the major focus of the investigation. The research proposed that such aid should continue under the President Barack Obama administration. Approach: The approach taken used … …Journal of Social Sciences, Vol. 5, Issue 2 · 30 Jun 2009 · 8,053 accessesView PDFCite
Research ArticleOpen accessIn the abstractReduction of Ammonia Loss from Urea through Mixing with Humic Acids Isolated from Peat Soil (Saprists)Regis Bernard, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Application of urea as a source of nitrogen fertilizer has an adverse effect on ammoniacal loss to the environment. This study was conducted to reduce ammonia loss from urea by mixing with Humic Acids (HA) isolated from Saprists peat. Approach: The effects of urea amended with four different amounts of humic acids, 0.25, 0.50, 0.75 and 1.00 g … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,846 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiological Control of Sclerotinia sclerotiorum, Causal Agent of Sunflower Head and Stem Rot Disease, by Use of Soil borne Actinomycetes IsolatesF. Baniasadi, G. H. Shahidi Bonjar, A. Baghizadeh et al.Problem statement: High level of biosafety and non adverse effects on the environment of biocontrol strategies of pest management, are priorities of tomorrow's world agriculture. Actinomycetes are active biocontrol agents due to their antagonistic properties against wide range of plant pathogens particularly fungi. Fungal pathogens are liable for a big part of damages in agriculture economy. Approach: In the present … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 11,166 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Methyl Tert-Butyl Ether (MTBE) Contaminated Water by Using In situ Catalytic and Biological Combined TechniquesA. Nikpay, H. Kazemian, M. SadeghiThe hydrolysis reaction of Methyl Tert-Butyl Ether (MTBE) into biodegradable products was studied on as-synthesized and commercial H-MFI zeolites. The effect of synthesis procedure and SiO2/Al2O3 ratio was investigated. The results obtained were indicated that H-MFI zeolites were effective in MTBE hydrolysis and increasing of the Si/Al ratio promotes the hydrolysis reaction. The amount of produced TBA was always lower … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vitro Metabolism Studies of Polybrominated Diphenyl Ethers Using Rat and Human Liver MicrosomesShun Wen Cheng, Kathleen Randall, Anne T. KotchevarA number of studies have recently reported the bioaccumulation of the commonly used fire retardants, Polybrominated Diphenyl Ethers (PBDEs), in humans and wildlife. Exposure of animals to PBDEs has been shown to result in developmental neurological, reproductive abnormalities and the disruption of endocrine function. Thyroid hormone equilibria was also shown to be altered by PBDE exposure. There is evidence that … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 6,998 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficacy of Pravastatin in Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI) and Protease Inhibitor (PI)-based HAART in HIV-Infected PatientsSusan A. Eaton, Anita P. Rahman, Sean T. Nguyen et al.Pravastatin has generally been considered a safe and effective option for HIV-infected patients on highly active antiretroviral therapy (HAART). However, pravastatin concentrations are known to significantly decrease with concomitant efavirenz (EFV) use. Currently there are no studies determining if these reductions in pravastatin possibly translate into an attenuation of its lipid lowering efficacy when used in HIV-infected patients on non-nucleoside … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 6,959 accessesView PDFCite
