Authentic induced pluripotent stem cells (iPSCs), capable of giving rise to all cell types of an adult animal, are currently only available in mouse. Here, we report the first generation of bovine iPSC-like cells following transfection with a novel virus-free poly-promoter vector. This vector contains the bovine cDNAs for OCT4, SOX2, KLF4 and c-MYC, each controlled by its own independent promot...

abstract background and aims: to identify and isolation of viruses a susceptible cell is need which can be primary or line. the use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. irkhbk cell line was originated from primary cells of bovine kidney by continuous passage. the aim of this study was to introduce the irkhbk cell lin...

BACKGROUND: Infectious Bovine Rhinotrachitis (IBR) caus-ed by Bovine Herpes Virus-1 (BoHV-1) was first, observed in one of the Tehran Industrial cattle breeders, with importation of cattle in 1965. Later, the isolation of bovine herpes virus approved the existence of the disease in the most of the provinces of the Iran. OBJECTIVES: Presence of antibodies against BoHV-1 was evaluated in young bo...

Using sera from hosts infected with bovine leukaemia virus (BLV), human T cell lymphoma virus types I and II (HTLV-I and -II), or simian T cell lymphoma virus type I (STLV-I), we found that the major gag proteins of these viruses cross-react immunologically. The specificity of this cross-reactivity was demonstrated by absorption using purified viral proteins, virus lysates and extracts of infec...

VirOligo is a database of virus-specific oligonucleotides. The VirOligo database consists of two tables, Common data and Oligo data. The Oligo data table contains PCR primers and hybridization probes used for detection of viral nucleic acids and the Common data table contains the experimental conditions used in their detection. Each oligonucleotide entry contains links to PubMed, GenBank, NCBI ...

An emerging amount of data indicates a correlation between gender-related factors and regulation of virus infection and supports what is known in clinical circles, that these topics are of great importance in many infectious diseases. In the present study we found that young adult NMRI male mice are more susceptible to infection by a variant of Friend murine leukaemia virus, FIS-2, than are fem...
