Research ArticleOpen accessIn the abstractPhytoremediation of Anaerobic Digester Effluent for Water Purification and Production of Animal FeedA. E. Ghaly, H.A. FaragThe application of phytoremediation for purification of an anaerobically treated dairy manure and production of forage crops was investigated. Four crops (two cereals and two grasses) were examined for their ability to grow hydroponically and to remove pollutants (nutrients) from dairy wastewater. The preliminary experiments showed that timothygrass and orchardgrass did not perform well as aquatic plants. Only 24 and … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 8,201 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Characterization of Soybean Mosaic Virus NIa Protein and its Processing Event in Bacterial ExpressionBong K. Choi, Jae S. Park, Hye J. Ahn et al.Soybean mosaic virus (SMV)-CN18 is an Rsv resistance-breaking (RB) isolate to overcome soybean resistance genes Rsv1, Rsv3 and Rsv4. The aim of this study was to characterize nuclear inclusion protein a (NIa protein) of RB isolate at the molecular level and demonstrate its processing into genome-linked protein (VPg) and NIa-Pro domains in Esherichia coli containing a bacterial expression pET vector … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 6,902 accessesView PDFCite
Research ArticleOpen accessIn the abstractUpgrading of Light Dewaxed Oil through Hydrofinishing and Additives Blending for Producing Automatic Transmission FluidGamal Abdel-Nasser Gohar, Mohamed Sherif El-Gayar, Abd El-Moneim Ibrahim et al.Light dewaxed oil was produced through dewaxing process of the light waxy distillate raffinate of crude oil from Western Desert of Egypt using methyl ethyl ketone/toluene mixed solvent. Hydrofinishing process was used to remove the non-hydrocarbon constituents and to improve the physicochemical properties of the produced oils such as color, viscosity index, inhibition responses, oxidation and thermal stability. The operating … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study of Residual Oils Recovered from Spent Bleaching Earth: Their Characteristics and ApplicationsLoh Soh Kheang, Cheng Sit Foon, Choo Yuen May, Ma Ah NganThis study described the extraction of residual oils of spent bleaching earth (SBE) from palm oil refining industry, the properties and applications of residual oils obtained there from. Residual oils of SBE (acid-activated, WAC and neutral, NC) were recovered via solvent and supercritical-fluid (SC-CO2) extraction. The yields of residual oils recovered from WAC were higher than those from NC using … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 9,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntitussive Activity Directed Isolation of Compounds from Onosma hispidumShahina Naz, Rafeeq A. Khan, Rahmanullah Siddiqi, Syed A. SayeedThe chemical investigation of the ethanolic extract of the root bark of Onosma hispidum following antitussive activity directed isolation led to the isolation of 4-hydroxy-3-methoxy cinnamic acid (mCA) and 4-hydroxy-3-methoxy benzoic acid (mBA) which have been reported for the first time in this species. Antitussive activity of the compounds was evaluated by reduction in frequency of cough induced by SO2 … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 1 · 31 Mar 2006 · 7,322 accessesView PDFCite
Research ArticleOpen accessIn the abstractSupercritical Fluid Extraction of Palm CarotenoidsPuah C. Wei, Choo Y. May, Ma A. Ngan, Chuah C. HockThe extraction of carotenoids from crude palm oil was carried out in a dynamic (flow- through) supercritical fluid extraction system. The carotenoids obtained were quantified using off-line UV-visible spectrophotometry. The effects of operating pressure and temperature, flow rate of the supercritical carbon dioxide (SC-CO2), sample size of feed used on the solubility of palm carotenoids were investigated. The results showed … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 8,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards Identifying Immunogenic Targets in Visceral Leishmaniasis: Role of 17kDa and 63kDa PhosphoproteinsShubhankar K Singh, Sanjiva Bimal, Diwakar S. Dinesh et al.We observed predominant phosphorylation at Protein Kinase C (PKC-α) residue in seven immunoreactive proteins of virulent Leishmania donovani parasites. These phosphoproteins were tested for their ability to stimulate T-cells for secretion of Macrophage Migration Inhibition Factor (MIF) in comparision to crude soluble antigen in Visceral Leishmaniasis (VL) patients. Two of these phosphorylated L. donovani antigens led Leishmania to present these … …American Journal of Immunology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,756 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiological Control of Fusarium oxysporum f. sp. melonis, the Causal Agent of Root Rot Disease of Greenhouse Cucurbits in Kerman Province of IranSara Shafii Bafti, Gholam H.S. Bonjar, Sonia Aghighi et al.Antagonistic activity of 178 soil actinomycete isolates was assayed against Fusarium oxysporum f. sp. melonis Schlecht, Emend (Snyde and Hansen) cause of root rot and fusarium wilt of greenhouse cucurbits in Kerman Province, southeast of Iran. From tested isolates, Streptomyces olivaceus (strain 115) showed anti-fusarium activity revealed through screening and bioassays by agar disk and well-diffusion methods. The active strain … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,993 accessesView PDFCite
