Research ArticleOpen accessIn the abstractPotential Role of Migratory Quail in Spreading of Some Zoonotic Pathogens in EgyptAhmed I. Youssef, Dalia H. MansourThis study aimed to illustrate the potential role of wild migratory quails in the epidemiology of some zoonotic pathogens in Egypt. Ninety four apparently healthy migratory quails were collected from public markets after being trapped during hunting season from the North Sinai. Oral, cloaca and organs (liver, lung and heart) swabs were collected for bacteriological and viral examination. Bacteriological examination … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 4 · 13 Dec 2014 · 7,530 accessesView PDFCite
Research ArticleOpen accessIn the abstractHypoxia-Inducible Factor 1α Expression in Chorionic Tissue and Decidua of Women with Spontaneous Abortion at the First Trimester of PregnancyE. V. Mashkina, K. A. Kovalenko, E. V. ButenkoOxygen-regulated genes expression has important role in pre-implantation embryonic metabolism regulation. Hypoxia Inducible Factor (HIF) regulated by hypoxia oxygen tension is crucial for placenta development. But the data about its role in spontaneous abortion is very poor. Thus, we aimed to determine an expression level of HIF-1α in chorionic tissue and decidua at pregnancy. Samples of chorionic tissue and decidua … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 4 · 18 Nov 2014 · 6,862 accessesView PDFCite
Research ArticleOpen accessIn the abstractATRA AS A POTENTIAL ANTIMETASTATIC AGENT IN COLORECTAL ADENOCARCINOMARobert Edwards, Kambiz Afrasiabi, Kehui WangThe family of Retinoic acid compounds have long been the subject of intense study and interest as chemo prophylactic agents. This dates back to their therapeutic effect in leukoplakia Where ATRA was shown to lead to the reversal of premalignant lesions and Subsequent reports on their use in metastatic colorectal adenocarcinoma and a vast array of other malignant disorders as … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 26 Mar 2014 · 7,344 accessesView PDFCite
Research ArticleOpen accessIn the abstractSCREENING FOR CUCUMBER MOSAIC RESISTANT LINES FROM THE OVULE CULTURE DERIVED DOUBLE HAPLOID CUCUMBERSParichat Plapung, Sirisupaporn Khamsukdee, NutthaPotapohn, Prasartporn SmitamanaCMV is one of the major destructive viruses worldwide and commercial CMV resistant cucumber is very rare. Therefore we aimed to establish the ovule derived resistant lines used for the breeding program. Haploid plants of sixty-eight cucumber lines were successfully obtained by culturing the un pollinated ovaries harvested one day before an thesis on a modified MS medium supplemented with … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 28 Feb 2014 · 7,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancement of Nutritional Quality of Wheat (Triticum aestivum) by Metabolic Engineering of Isoflavone PathwayAhmed Mohamed El-Shehawi, Abdelmegid Ibrahim Fahmi, Mona Mohamed Elseehy, Hesham Ahmed NagatyIsoflavones are large group of secondary metabolites produced in legumes such as soybeans. They have essential biological functions as nutraceutical and health functions for human. They are involved in plant resistance to biotic and abiotic stresses, symbiotic relationship with nitrogen-fixing organisms and plant competition (allelopathy). In this report, isoflavonoids were expressed in wheat (Triticum aestivum) via introducing the key enzymes … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,135 accessesView PDFCite
Research ArticleOpen accessIn the abstractEpigenetic Mechanisms in Hepatitis C Virus-Associated Hepatocellular Carcinoma: A Potential New Link Between Stem Cells, Virology and CancerQinghua Feng, Sajida Hassan, Trina Das et al.Recent studies suggest that epigenetic mechanisms are not only essential for the dynamic transcriptional regulation in embryonic and somatic stem cells, but are also actively involved in tumorigenesis: genes important for pluripotency are epigenetically regulated and aberrant epigenetic changes have been detected in virtually all human malignancies studied, including Hepatocellular Carcinoma (HCC). Infection with Hepatitis C Virus (HCV) is a … …Current Research in Medicine, Vol. 4, Issue 1 · 12 Mar 2013 · 8,038 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of ced-9 dsRNA on Caenorhabditis elegans and Meloidogyne incognitaRobert T. Gaeta, Abdellatif Bahaji, Glenda W. Polack, Alejandro Calderón-UrreaAbstract: Problem Statement: In metazoans Programmed Cell Death (PCD) is essential for proper development. Suppression of PCD is needed to guarantee cell survival and in the nematode Caenorhabditis elegans the regulation of PCD is accomplished by the function of the ced-9 gene. Approach: In this work the use of double stranded RNA (dsRNA) to knock-down ced-9 gene function was tested … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 9,452 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Evaluation of Three Pair Primers for Exon 1 Amplification of Hyaluroglucosaminidase-1 GeneUsman Sumo Friend Tambunan, Sylvia Sugito, Arli Aditya ParikesitProblem statement: Hyaluronidase is an enzyme which catalyze hydrolysis of Hyaluronan (HA). Hyaluronan is important in cell migration during embryonic development, cellular proliferation and differentiation and has a structural role in connective tissues. Hyaluronidase deficiency is correlated with mucopolysaccharidosis IX. In human, hyaluronidase is encoded by HYAL1 gene. The mutation study of HYAL1 gene was carried out by many researchers, … …OnLine Journal of Biological Sciences, Vol. 10, Issue 2 · 16 Jun 2010 · 8,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimultaneous Presence of Growth and Remodeling in the Bone Adaptation TheorySeyyed Amir Hooshiar Ahmedi, Gholamreza Rouhi, Hamidreza Katouzian, Seyyed Ali Hooshiar AhmediMechanical forces acting on bone during growth affect their final shape and strength. Mechanoregulation of bone growth is maybe recognized in embryogenesis, and also in the adaptation of the adult skeleton to changes in mechanical loading. By combining equations describing bone remodeling and growth with an iterative finite element analysis, a computational model to simulate the simultaneous effects of bone … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,166 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Bruchid Beetles (Burchidius Arabicus Decelle) Infestation on the Germination of Acacia tortilis (Forssk.) Hayne) SeedsM. Al Jabr AhmedThe role of bruchid beetle infestation on seed germination of Acacia tortilis (Forssk.) Hayne) Mimosaceae under different incubation temperatures and degrees of scarification was studied under controlled conditions. Results indicate that seed germination was highest (96%) in scarified seeds at 25-35°C incubation temperature, whereas, it was only 28% in intact seeds. Seeds infected by bruchid beetles with one or two … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,296 accessesView PDFCite
