Research ArticleOpen accessIn the abstractEffect of Exercise Training on Adiponectin Receptor Expression and Insulin Resistance in Mice Fed a High Fat DietNaglaa Fathy Alhusseini, Nasr Arafat Belacy, Enas Mohammed Kasem, Mona Maher AllamProblem statement: Adiponectin is an adipocyte secreted hormones, exerts its effects via the specific receptors. AdipoR1 and adipoR2 and plays a pivotal role in lipid and glucose metabolism. Approach: We investigated the effect of increased physical activities on insulin resistance and if this effect is modulated through adiponectin receptor expression. Results: We also assessed the effect of High Fat Diet … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 2 · 30 Jun 2010 · 9,951 accessesView PDFCite
Research ArticleOpen accessIn the abstractConcentration of Zn, Cu and Pb in Some Selected Marine Fishes of the Pahang Coastal Waters, MalaysiaB. Y. Kamaruzzaman, M. C. Ong, S. Z. RinaProblem statement: Heavy metals constitute one of the most hazardous substances that could be accumulated in biota. Fish populations exploited by man often live in coastal area environments that contain high levels of heavy metals, coming from human activities such as industrial and agricultural wastes. A problem to deal when using fishes as biomonitors of heavy metals is the relationship … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 10,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval of Cadmium, Copper, Lead and Nickel from Aqueous Solution by White, Yellow and Red United Arab Emirates SandL. Pappalardo, F. Jumean, N. AbdoProblem statement: To remove toxic heavy metal ions from wastewater using local sand as a low cost adsorbent. Approach: Removal efficiency of Cd(II), Cu(II), Pb(II) and Ni(II) from aqueous solution by white, yellow and red UAE sand was investigated at 25.0°C using the methods of batch equilibrium adsorption and column filtration. In each case, a mixture containing 20 ppm of … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,600 accessesView PDFCite
Research ArticleOpen accessIn the abstractStandardization of Metal-Based Herbal MedicinesArun Sudha, V. S. Murty, T. S. ChandraProblem statement: Standardization of herbal drugs is a burning topic in herbal drug industry today. Standardization is difficult because they are usually mixtures of many constituents and the active principle in most cases is unknown. However it is possible to generate a physico-chemical fingerprint for the standardization of these drugs with reference to authentic drugs, for monitoring variation between preparations … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,904 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Quercetin on Diabetes-Induced Alteration in CYP3A Activity and Bioavailability of Pioglitazone in RatsSudhir Niranjan Umathe, Pankaj Vinod Dixit, Jignesh Manubhai Vaghasiya, Nishant Sudhir JainProblem statement: Quercetin-a common bioflavonoid, is present in herbal preparations consumed by diabetic patients along with routine anti-diabetic agents. We recently showed that quercetin increases the bioavailability of pioglitazone in non-diabetic rats. Thus, present study investigated whether this pharmacokinetic interaction is also evident in diabetic animals, especially because diabetic subjects have altered gastrointestinal (GI) function and CYP3A activity. Approach: The … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 7,818 accessesView PDFCite
Research ArticleOpen accessIn the abstractMountain Sheep: An Environmental Epidemiological Survey of Variation in Metal Exposure and Physiological Biomarkers Following Mine DevelopmentLawrence K. Duffy, Michael W. Oehler, R. Terry Bowyer, Vernon C. BleichProblem Statement: Anthropogenic activities, such as mining and industrial operations, are a major environmental source of metal exposure for wildlife. Quantitative data regarding biochemical effects of exposure to mineral extraction on mountain sheep, Ovis canadensis, are limited, although their habitats are becoming increasingly affected by expanded resource development. Decisions relating to environmental protection and wildlife conservation should be based on … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Characteristics of Leachate and Groundwater Pollution at Municipal Solid Waste Landfill of Ibb City, YemenEsmail Al Sabahi, S. Abdul Rahim, W.Y. Wan Zuhairi et al.Problem statement: Yemen one of the developing country suffering from water pollution. Landfill is one of the source of water pollution. There are several boreholes located close to Ibb landfill used for drinking water. A study of composition of landfill leachate and groundwater pollution was conducted at Ibb landfill, which is located at Al-Sahool area, north of Ibb City, Yemen. … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 9,186 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeochemical Distribution of Trace Metals and Assessment of Anthropogenic Pollution in Sediments of Old Nakagawa River, Tokyo, JapanH.M. Zakir, Naotatsu Shikazono, Kazuo OtomoThe geochemical distributions of cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb) and zinc (Zn) were examined in sediments collected from Old Nakagawa River (NR), Tokyo, Japan. A widely used 5-step sequential extraction procedure was employed for the fractionation of the metals and the concentrations were measured in the liquid extracts by inductively coupled plasma mass spectrometry (ICP-MS). The association … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,453 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeochemistry of Sediment in the Major Estuarine Mangrove Forest of Terengganu Region, MalaysiaB.Y. Kamaruzzaman, M.C. Ong, M.S.Noor Azhar et al.Surface sediments collected from seven estuarine mangrove forests of Terengganu region (100 sampling points) were anaylzed for Pb, Cu and Zn using the sensitive Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The average concentration of Pb, Cu and Zn were 10.5±7.12 µg g-1 dry weights, 31.1±16.5 µg g-1 dry weights and 20.8±13.3 µg g-1 dry weights, respectively. The statistical analysis of … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,321 accessesView PDFCite
Research ArticleOpen accessIn the abstractHomotopy Perturbation Method and Variational Iteration Method for Solving Zakharov-Kuznetsov EquationB. Ganjavi, H. Mohammadi, D.D. Ganji, A. BarariThis article investigates a nonlinear dispersive Zakharov-Kuznetsov ZK (3, 3, 3) equation. This equation governs the behavior of weakly nonlinear ion-acoustic waves in plasma comprising cold ions and hot isothermal electrons in the presence of a uniform magnetic field. Homotopy Perturbation Method (HPM) and Variational Iteration Method (VIM) are implemented for solving the ZK equation. Homotopy results were compared with … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,798 accessesView PDFCite
