Construction and characterization of a hybrid mouse mammary tumor virus/murine leukemia virus-based retroviral vector.
Mouse mammary tumor virus (MMTV)-based vectors are characterized by low titers. In an effort to transfer MMTV-specific regulation of gene expression to a more efficient murine leukemia virus (MLV) vector, we have replaced the complete 3' U3 region of MLV with the complete U3 region of MMTV. Virus titers were not significantly affected by this modification, there was no impairment of reverse tra...
متن کاملdetection of bovine leukemia virus infection by nested-pcr analysis
bovine leukemia virus (blv) is a retrovirus causing a chronic leukemia/lymphoma in cattle in many countries around the world. screening for antibodies by elisa has been the primary means of detecting the presence of this virus. it is not yet known if this assay will detect antibodies in all cattle during a concomitant bovine leukemia virus infection. the polymerase chain reaction (pcr) of the t...
متن کاملconstruction of vector fields with positive lyapunov exponents
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
15 صفحه اولPrevalence of bovine leukemia virus (BLV) infection in the northeast of Iran
The purpose of this study was to determine the prevalence of bovine leukemia virus (BLV) in Khorasan Razavi and Khorasan Shomali provinces which are the main provinces located in the northeast of Iran. Total number of 429 blood samples were collected from industrial dairy herds. The samples were categorized based on province, age (2-3, 4-6, and 7-10 years old), calving (≤ 2, 3-5, and > 5) and h...
متن کاملMolecular and Serological Evaluation of Bovine Leukemia Virus in Water Buffaloes of Southern Iran
BACKGROUND: Bovine leukemia virus (BLV) is an oncogenic deltaretrovirus causing a persistent lifelong infection of B lymphocytes. In addition to the domestic cattle, the virus can also infect water buffaloes. OBJECTIVES: Recent investigations have demonstrated the increasing prevalence of BLV infection among cattle population in Iran. Large popul...
