Research ArticleOpen accessIn the abstractComparative Physiological and Molecular Study of Some Sheep Breeds in Saudi ArabiaMohammad S. AL-Harbi, Hamed S. Alwagdany, Sayed A.M. AmerNaemi, Heri, Najdi and Sawakni sheep breeds inhabiting Kingdom of Saudi Arabia were studied on both physiological and molecular bases. Native polyacrylamide gel-electrophoreses for two enzymes Malate Dehydrogenase (Mdh) and Malic Enzyme (Me) recorded 5 isoenzyme loci from which 4 were polymorphic and 1 was monomorphic. Mdh showed three fractions, the first was recorded in Sawakni and Najdi breeds, the … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 8,388 accessesView PDFCite
Research ArticleOpen accessIn the abstractPorcine Respiratory and Reproductive Syndrome Virus Vaccinology: A Review for Commercial VaccinesV. G. PapatsirosPorcine Reproductive and Respiratory Syndrome (PRRS) since its appearance in Europe in the early 1990’s has resulted in tremendous economic losses. Under field conditions vaccination is one of the most efficient strategies for the prevention and control of PRRS. The aim of this study is to perform the PRRSV vaccinology regarding current status of commercial vaccines in Europe. There are … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 5 Nov 2012 · 8,123 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dose-Response of Zinc and Manganese on Siderophores ProductionMehri Ines, Khessairi Amel, Turki Yousra et al.Problem statement: This study was conducted to find and determine whether the siderophores of the four environmental Pseudomonas spp. isolates possess a sequestering activity towards essential transition metals (Zn and Mn) other than iron. Approach: Four fluorescent Pseudomonads isolated from various environments, were characterized analytically (Isoelectric focusing), biologically (pyoverdine-mediated uptake) and genetically (16S rDNA sequencing). By means of spectrophotometric measurements, … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 10 Mar 2012 · 7,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy on Nitrogen Concentration of Corn HybridsPravin Gautam, Dawn Gustafson, Zeno Wicks IIIProblem statement: Though Nitrogen (N) is vital in different physiological and developmental processes in plants and animals, it poses several environmental, nutritional and health problems, if present in excess amounts. Reduction in excess input of N into the soil, thereby reducing environmental problems and consequently nutritional and health problems, can be achieved by balancing their concentration in animal feed. Therefore, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 10 Mar 2011 · 8,273 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphological Variability and Races of Fusarium oxysporum f.sp. ciceris Associated with Chickpea (Cicer arietinum) CropsRosa Marina Arvayo-Ortiz, Martin Esqueda, Evelia Acedo-Felix et al.Abstract: Problem statement: Mexico is the third largest producer and exporter of chickpea (Cicer arietinum), with the states of Sinaloa and Sonora accounting for 70 and 20% of Mexico’s production, respectively. The most damaging disease affecting this species is caused by Fusarium oxysporum f.sp. Ciceris (FOC), which causes losses of up to 60% in Sonora. The objective of this study … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 31 Jan 2011 · 8,853 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Widely Used Diagnostics "DNA Microarray"-A ReviewR. Manoj KumarProblem statement: DNA microarray technique is one of the latest advances in the field of molecular biology and medicine. It is a multiplex technique used in combination of bioinformatics and statistical data analysis. Since, 1995, the technique offers the possibility of conducting tens or hundreds of thousands of simultaneous hybridizations. Approach: This increased experimental efficiency permits high throughput and whole … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,787 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrade Related Environmental Measures in Multilateral Environmental Agreements and the WTO: Irreconcilable Differences?Nidhi SinghProblem statement: WTO adopted a multilateral trading system without ignoring the importance of protecting environment. Exceptions in Article XX, Clause (b) and (g) checks trade at the cost of environment. It is difficult to establish a relationship between Trade Related Environmental Measures (TREMs) in Multilateral Environmental Agreements (MEAs) and World Trade Organization (WTO) rules. For the past ten years there … …American Journal of Economics and Business Administration, Vol. 1, Issue 3 · 30 Sep 2009 · 8,621 accessesView PDFCite

Research ArticleOpen accessIn the abstractAn Inducible System for the Identification of Target Genes for a Regulator in MycobacteriaShruti Jain, Garima Khare, Pushplata Tripathi, Anil K. TyagiWe described principle and application of an inducible system for identification of target genes of a given mycobacterial protein with a regulatory function. This vector system, a promoterprobe vector, carries (i) promoterless lacZ as the reporter gene and (ii) the mycobacterial gene encoding the regulatory protein under the transcriptional control of the promoter of highly inducible mycobacterial gene encoding acetamidase. … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 7,249 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccumulation of Cholesterol Esters in ex vivo Lymphocytes from Scrapie-susceptible Sheep and in Scrapie-infected Mouse Neuroblastoma Cell LinesAlessandra Pani, Claudia Norfo, Claudia Abete et al.Our studies on the role of cholesterol homeostasis in the pathogenesis of scrapie in sheep, revealed abnormal accumulation of cholesterol esters in brains and in ex vivo skin fibroblasts from genetically scrapie-susceptible, as compared to sheep with resistant genotype. We now report that PBMCs isolated from scrapie-susceptible sheep, as well as mouse neuroblastoma cell lines persistently infected with two different … …American Journal of Infectious Diseases, Vol. 3, Issue 3 · 30 Sep 2007 · 6,955 accessesView PDFCite
