Case ReportOpen accessEvery word in the titleVaricella Zoster Virus Causing Aseptic Meningitis Without Fever or Rash in an Immunocompetent PatientFazal I RaziqVaricella-Zoster Virus (VZV) is known to be a cause of aseptic meningitis and can be potentially fatal. VZV meningitis can arise in immunodeficient and more rarely, immunocompetent hosts. We present here a rare case of VZV causing meningitis in a 44-year-old immunocompetent man. He presented with an isolated headache without any fever or rash. CSF PCR for VZV DNA was … …American Journal of Infectious Diseases, Vol. 16, Issue 2 · 29 Apr 2020 · 8,022 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Some Vaccination Programs in Protection of Experimentally Challenged Broiler Chicken against Newcastle Disease VirusMousa A. Ayoub, Wael K. Elfeil, Diaa El Boraey et al.The current study was carried out to evaluate efficiency of different vaccination programs in protecting broiler chicken against Virulent Viscerotropic Strain of Newcastle disease virus. Different live and inactivated NDV vaccines were used throughout the experiment including; ND-HB1,Elite, LaSota, Inactivated GII and Inactivated GVII. Broiler chicks were divided into 8 groups; 6 groups undergo different vaccination programs against NDV while … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 3 · 16 Sep 2019 · 8,404 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVariations in Pathogenicity and Molecular Characterization of Infectious Bursal Disease Virus (IBDV) In EgyptMahmoud E. Sedeik, Ashraf M. Awad, Heba Rashed, Wael K. ElfeilInfectious bursal disease consider a vital threat to poultry industry worldwide and It has special potentiality in Egypt as the country become endemic with several clades from avian influenza from both types highly pathogenic (H5N1 and H5N8) and low pathogenic one (H9N2). The Egyptian government depends on the inactivated vaccine strategy to control avian influenza and any infection with IBD … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 2 · 18 May 2018 · 8,485 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe SEIR Dynamical Transmission Model of Dengue Disease with and Without the Vertical Transmission of the VirusPratchaya Chanprasopchai, I. Ming Tang, Puntani PongsumpunThe transmission of dengue disease when there is a possibility of Vertical Transmission (VT) is studied using mathematical modeling. In the normal case, the mosquito is infected by the dengue virus when it bites an infectious human being. Evidence is gathering that the mosquitoes can also be infected through sexual contact with infected male mosquito. To see the possible consequence … …American Journal of Applied Sciences, Vol. 14, Issue 12 · 2 Jan 2018 · 9,061 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInflammatory Effects of Co-Exposure to Heavy Metals (Cd and Pb) and Respiratory Viruses (229E, OC43, and H3N2) on IL-6 and IL-8 Responses in U87 Glioblastoma CellsHyeokjun Yun, Qian-Wen Wang, Jae Kyung KimCo-exposure to heavy metals and viruses can pose threats to cellular health by increasing cytotoxicity and inflammatory cytokine expression. We aimed to elucidate the interactions between these factors inhuman glioblastoma cells (U87). U87 cells were exposed to influenza A virus (H3N2), coronaviruses OC43 and 229E, and heavy metals Cd and Pb. Cell viability and cytotoxicity were assessed through WST-8 and … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 5 Jul 2025 · 5,506 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Comparison of RT-LAMP, RT-PCR and Dot-Blot Hybridization for Detection of Jembrana Disease VirusAsmarani Kusumawati, Tenri A. Wanahari, Issabellina D. Tampubolon, Basofi A. MappakayaJembrana disease virus is a viral pathogen that causes Jembrana disease in Bali cattle (Bos javanicus) with high mortality rate. Infection of Jembrana Disease Virus (JDV) on Bali cattle have caused substantial economic losses for farmers in Indonesia and Australia. In order to control the spread, development of a sensitive detection method is important. In this study, we used three … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 2 · 26 Jun 2015 · 7,802 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDocking and Molecular Dynamics Simulations in Potential Drugs Discovery: An Application to Influenza Virus M2 ProteinMarine E. Bozdaganyan, Philipp S. Orekhov, Nicola L. Bragazzi et al.Molecular docking is a common method for searching new potential drugs. Improvement of the results of docking can be achieved by different ways-one of them is molecular dynamics simulations of protein-ligand complexes. As a model for our research we chose M2 membrane protein from influenza virus. M2 protein is a high selective tetrameric pH-gated proton channel. It was previously shown … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 3 · 11 Nov 2014 · 8,674 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMOLECULAR CHARACTERIZATION ON THE BASIS OF HA, NA AND M GENE REVEALED CHANGES IN CRITICAL AMINO ACID POSITIONS OF INFLUENZA A (H3N2) VIRUS CIRCULATING IN INDIA DURING 2011-2013Sachin Kumar, Shashi Khare, Bano Saidullah et al.Influenza a (H1N1) virus is responsible for acute respiratory infection in human, which occasionally causes epidemic and rarely a pandemic. Full length DNA sequencing of HA, NA and M gene of H3N2 virus from year 2011-2013 was performed for determination of the circulating strains in India along with monitoring status of various mutations associated with drug resistance and virulence.

Research ArticleOpen accessEvery word in the titleDetection of Antibodies Against Bovine Herpes Virus 1, Bovine Viral Diarrhea Virus and Bovine Respiratory Syncytial Virus in Early and Ultra-Early Weaned Beef CalvesDiego Daniel Gonzalez, Juan Sebastian Vittone, Martin Lado et al.Bovine respiratory disease is the leading cause of morbidity and mortality in weaned calves. In Argentina, two weaning practices have been implemented. In the early weaning, the calf is removed from the cow at 60-70 days of age while in ultra-early weaning the calf is weaned at 30-45 days of age. The purposes of both systems is to improve cow … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 4 · 29 Oct 2013 · 8,388 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEpigenetic 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).
