An increasing number of hepatitis E virus (HEV) infections in industrialized countries have been foodborne and linked to the consumption undercooked pork products. To date, data on prevalence HEV products sold United States is limited no standard processing method exists for detection foods. In order develop a products, ground liver were selected development. Murine norovirus (MNV) was used as ...
To better understand the potential environmental health risk presented by West Nile virus (WNV)-contaminated feces, we quantified the amount of WNV present in the feces of experimentally infected American crows (Corvus brachyrhynchos) and fish crows (Corvus ossifragus). Peak fecal titers ranged from 10(3.5) to 10(8.8) plaque-forming units (PFU)/g for 10 American crows and from 10(2.3) to 10(6.4...
A simple method, primer specific and mispair extension analysis (PSMEA) with pfu DNA polymerase was developed for genotyping. PSMEA is based on the unique properties of 3'-->5' exonuclease proofreading activity. In the presence of an incomplete set of dNTPs, pfu was found to be extremely discriminative in nucleotide incorporation and proofreading at the initiation step of DNA synthesis, complet...
Prolyl oligopeptidase (POP), the paradigm of a serine peptidase family, hydrolyses peptides, but not proteins. The thermophilic POP from Pyrococcus furiosus (Pfu) appeared to be an exception, since it hydrolysed large proteins. Here we demonstrate that the Pfu POP does not display appreciable activity against azocasein. The autolysis observed earlier was an artefact. We have also found that the...
Abstract This paper summarizes the emissivity measurements performed on plasma-facing units (PFU) of WEST lower divertor during first phase running with a mix actively cooled ITER-like PFUs made bulk tungsten (W) and inertially graphite coating tungsten. In situ assessments laboratory after removing W-coated ITER-grade from device are shown. The exhibit complex pattern strong variation as funct...
background: oncolytic herpes simplex virus (ohsv) vectors lacking γ34.5 has demonstrated anticancer effects without affecting normal cells. therefore, they are considered as ideal templates to construct efficient vectors for tumor targeting and cancer gene therapy. herein, we reported construction of three single/dually-labeled recombinant hsv-1 vectors, which provide an opportunity to replace ...
BACKGROUND The recent West African Ebola epidemic led to accelerated efforts to test Ebola vaccine candidates. As part of the World Health Organisation-led VSV Ebola Consortium (VEBCON), we performed a phase I clinical trial investigating rVSV-ZEBOV (a recombinant vesicular stomatitis virus-vectored Ebola vaccine), which has recently demonstrated protection from Ebola virus disease (EVD) in pha...
To develop vaccination strategies against HIV-1 infection aimed to specifically enhance the cell-mediated immunity (CMI), we have engineered vaccinia virus (VV) recombinants expressing HIV-1 Env (rVVenv) and murine IL-12 (rVVlucIL-12) genes or coexpressing both genes (rVVenvIL-12). In mice inoculated with rVVlucIL-12 there is a rapid clearance of the virus, and this correlates with the inductio...
Acute injury after adenoviral vascular gene transfer remains incompletely characterized. Here, we describe the early response (< or =days) in 52 New Zealand White rabbits undergoing gene transfer (beta-galactosidase or empty vector) or sham procedures to both carotid arteries. After gene transfer, arteries were either left in vivo for 1 hour to 3 days (in vivo arteries) or were excised immediat...
