Research ArticleOpen accessIn the abstractIncorporation of Omega-3 Fatty Acid and Synthesis of their Metabolites in Muscle Tissue in Mice Fed with Flaxseed and Perilla-Enriched DietSheisa Cyleia Sargi, Flavia Braidotti Stevanato, Marcia Machado de Oliveira Dalalio et al.Polyunsaturated fatty acids omega 3 and omega 6 are believed to have beneficial physiological effects on the human body. The present study aimed to evaluate the incorporation and synthesis of omega-3 fatty acid and their metabolites in muscle tissue in mice fed with a flaxseed and perilla-enriched diet. The animals were fed a diet supplemented with flaxseed and perilla meals … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 17 Apr 2013 · 7,017 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeciation of Arsenic Across Water-Sediment Interface of Falgu RiverRajeeva Ranjan, Rekha Rani, Ashay Bavishi et al.Two predominant species of arsenic compounds, As(III) and As(V), are found in soils and natural water and they have been classified as carcinogens. The focus of the present study was to examine the speciation of Arsenic (As) across the water-sediment interface at the confluence of drainage for Gaya city and the Falgu River. Gas Chromatography (GC) coupled to Inductively Coupled … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 31 Dec 2012 · 6,876 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnumeration of Microbes and Gas Production During Denitrification and Nitrogen Fixation Processes in SoilA. E. Ghaly, K. N. MacDonaldDry plant material contains 2-4% nitrogen, making it an essential nutrient for all plants. The nitrogen cycle regulates the pathways which transform nitrogen from a relatively inert dinitrogen gas to forms of organic nitrogen such as proteins and nucleic acids. Denitrification and nitrogen fixation are the two most important processes that remove and add nitrogen to the soil, respectively. The … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 11 Sep 2012 · 8,622 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlasma Fatty Acid Profile of Gestating Ewes Supplemented with FishmealMamun M. Or-Rashid, Rebecca Fisher, Niel Karrow et al.Problem statement: The very long chain n-3 polyunsaturated fatty acids (>18C) cannot be adequately synthesized by ruminant tissues to meet their requirements; therefore, their concentration in body depends on the supply through feed. It may be possible to improve the essential fatty acid status of ruminant animals, during gestation by manipulating the maternal diet with Fishmeal (FM). The objectives of … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 2 · 9 Jul 2012 · 8,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractGC-MS Analysis and PLS-DA Validation of the Trimethyl Silyl-Derivatization TechniquesKamalrul Azlan Azizan, Syarul Nataqain Baharum, Habtom W. Ressom, Normah Mohd. NoorProblem statement: Comparison and validation analysis of the conventional and power-adjusted Microwave-Assisted (MA) techniques of TMS derivatization using Gas Chromatography-Mass Spectrometry (GC-MS) and Multivariate Analysis (MVA) of Partial Least Squares Analysis (PLS-DA). Further improvement of the conventional technique using vigorous shaking was tested and analyzed. Approach: Cross-validation and response permutation test of PLS-DA and S-plot of Orthogonal Partial Least Squares … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 4 Jun 2012 · 10,325 accessesView PDFCite
Research ArticleOpen accessIn the abstractLevels of Dichlorodiphenyltrichloroethane and its Metabolites in the Blood of Agrochemicals RetailersAnthony J. Hotton, Jeoffrey T. Barminas, Sunday A. OsemeahonProblem statement: In tropical countries like Nigeria, the storage, sales and handling of pesticide by agrochemical retailers in indoor stores located in open markets and residential areas were fraught with problem of undesirable side effect. Serum levels of 1, 1, 1-trichloro-2, 2-di (4-chlorophenyl) ethane (DDT) and its metabolite were measured among agrochemicals retailers in Taraba, Nigeria. Approach: Blood samples from … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 22 Mar 2012 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractHistorical Changes in Polychlorinated Biphenyls Contaminated SedimentsViet D. Dang, David M. Walters, Cindy M. LeeProblem statement: PCBs contamination continues to pose a health risk to aquatic environments due to their recalcitrance and bioaccumulation. The Sangamo Weston/Twelvemile Creek/Lake Hartwell Superfund Site is an example of such a health risk as a result of PCBs discharged from a former capacitor manufacturing plant. We conducted a study in twelvemile creek (Clemson, SC, USA) to examine the temporal … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 25 Jan 2012 · 7,086 accessesView PDFCite
Research ArticleOpen accessIn the abstractRole of Evaporation in Degrading the "Oil Lakes"Al Rashed Ahamad, Colin BarkerProblem statement: Oil Spills are degraded by aerobic bacteria, water washing, evaporation and oxidation. In the absence of water the first two of these processes cannot operate. This is the situation in the low rainfall environment of the Kuwaiti desert where oil lakes still persist 20 years after the initial spills. The oils contain longer chain n-alkanes but have lost … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,750 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Metabolite Combinations Produced by Lactobacillus plantarum on Plasma Cholesterol and Fatty Acids in PigletsT. V. Thu, Loh Teck Chwen, H. L. Foo et al.Problem statement: Hypercholesterol and fatty acids in plasma are the main causes for cardiovascular disease. Reduction of risk factors from diet that associated with cardiovascular disease has much attention in animals as well as in human. The objective of this study was to investigate the effects of feeding liquid metabolite combinations produced by five L. plantarum strains on the fatty … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 27 Dec 2010 · 7,635 accessesView PDFCite
Research ArticleOpen accessIn the abstractAerobic Biodegradation of Per-Treated Methyl Tert-Butyl Ether By Ozonation in an Up-Flow-Fixed-Bed ReactorM. Sadeghi, M. Arbabi, A. Nikpey, G. MardaniProblem Statement: MTBE is a common pollution of environmental and has become an issue of considerable concern in recent years. It is not readily amenable to remove MTBE by conventional techniques in water treatment. In the present study, the feasibility of the continuous aerobic biodegradation of MTBE, was evaluated in an Up- Flow Fixed Bed Reactor (UFBR). Approach: The UFBR … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,623 accessesView PDFCite
