Research ArticleOpen accessIn the abstractDo Resistin and Tumor Necrosis Factor-α Relate to Changes in Insulin Resistance in Normal Pregnancy?Parvin Zareian, Abdolreza Sotoodeh Jahromi, Fateme Hemati Rad, Safar ZareiProblem statement: The purpose of this study was to evaluate the role of resistin and Tumor Necrosis Factor-α (TNF-α) in insulin resistance during pregnancy. Approach: Serum resistin and TNF-α concentrations were measured by ELISA in 86 healthy pregnant women (26, 23 and 37 of them in the 1st, 2nd and 3rd trimesters, respectively) and in 21 healthy non pregnant women … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 1 · 31 Mar 2010 · 7,810 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 abstractEffects of Rumen-Protected Methionine on Dairy Performance and Amino Acid Metabolism in Lactating CowsW.R. Yang, H. Sun, Q.Y. Wang et al.Problem statement: Free Met as one of the most limiting AA in dairy cows would be mostly degraded in the rumen. This study was to determine the effect of different levels of Rumen-Protected Met (RPMet) on dairy performance and serum amino acid metabolism. Approach: Thirty-six Holstein cows in similar condition were randomly assigned to six experimental treatments with six replicates … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Jan 2010 · 8,262 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Activity of Plant Extracts in Boer GoatsM. Worku, R. Franco, J. H. MillerProblem statement: The effect of extracts from Neem (Azadirachta indica), Wormwood (Artemisia absinthium) and Tobacco (Nicotiana tabacum) with added copper sulfate, on female Boer goats infected with gastrointestinal parasites (GIN) was evaluated. Approach: Following initial screening for infection, animals were artificially infected with a mix containing approximately 80% Haemonchus contortus and 20% Trichostrongylus spp. After 21 days, fecal samples were … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 21 Dec 2009 · 8,471 accessesView PDFCite
Research ArticleOpen accessIn the abstractSorption of Phenols: Influence of Groundwater pH and of Soil Organic Carbon ContentSilvia Fiore, Maria Chiara ZanettiProblem statement: Physical and chemical properties of soil, groundwater and pollutants deeply influenced the type and the strength of sorption phenomena involving hydrophobic organic contaminants: Soil fraction of organic carbon (foc) and cation exchange capacity, groundwater pH and pollutants hydrophobicity were with undoubtedly the predominant issues. Approach: In this study an experimental study of the sorption of phenol and 2-nitrophenol … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeltability and Stretchability of White Brined Cheese: Effect of Emulsifier SaltsKhaled Abu-Alruz, Ayman Suliman Mazahreh, Ali F. Al-Shawabkeh et al.Problem statement: This study was based on the hypothesis that by adding low concentrations of emulsifier salts, may specifically act on the cross linking bonds of the protein matrix, to the original brine (storage medium) it would be possible to induce meltability and stretchability in white brined cheese. Approach: A new apparatus for measuring the actual stretchability was designed and … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,093 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Survival and Nodule Occupancy of Pigeon pea Nodulating Rhizobium sp. ST1 expressing fegA Gene of Bradyrhizobium japonicum 61A152Falguni R. Joshi, Dhwani K. Desai, G. Archana, Anjana J. DesaiProblem statement: Rhizobial isolates belonging to genera (Rhizobium sp. and Mesorhizobium sp.) in our laboratory produced only catecholate type of siderophores. Although FhuA and FegA (ferrichrome receptors) homologs were found to be present in the sequenced genomes of few rhizobia (e.g., 1 in R. etli and 2 in Mesorhizobium sp. BNC1), laboratory isolates of the corresponding genera failed to utilize … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 30 Jun 2009 · 7,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Flavonoid, Quercetin, Inhibits HIV-1 Infection in Normal Peripheral Blood Mononuclear CellsMadhavan P.N. Nair, Zainulabedin M. Saiyed, Nimisha H. Gandhi, C. N. RamchandProblem statement: Flavonoids and related polyphenols, have been known to possess cardioprotective, anti-tumor, anti-inflammatory, anti-allergic and anti-viral activities. Previous studies have shown that flavonoid, quercetin significantly downregulates expression of pro-inflammatory cytokines in cultured cells via modulation of NFκB and p38MAPK signaling pathways. In the current study, we hypothesize that quercetin exerts anti-HIV activity by differential modulation of pro-and anti-inflammatory cytokine … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 12,184 accessesView PDFCite
