The vaccinia virus strain Western Reserve (WR) A34R gene encodes a C-type lectin-like glycoprotein, gp22-24, that is present in the outer membrane of extracellular enveloped virus (EEV) with type II membrane topology (S.A. Duncan and G.L. Smith, J. Virol. 66:1610-1621, 1992). Here we that a WR A34R deletion mutant (WR delta A34R) released 19- to 24-fold more EEV from infected cells than did WR ...
The kinematic structure of a sample of planetary nebulae, consisting of 23 [WR] central stars, 21 weak emission line stars (wels) and 57 non-emission line central stars, is studied. The [WR] stars are shown to be surrounded by turbulent nebulae, a characteristic shared by some wels but almost completely absent from the non-emission line stars. The fraction of objects showing turbulence for non-...
Studies of V79-171 cells were undertaken to determine what extracel lular or intracellular derivative of the drug WR-2721 is associated with radioprotection. The effect of preincubation at 23 ±1°Cwith WR-2721, and with derivatives of WR-2721 produced in medium containing alkaline phosphatase, upon survival of cells following subsequent -y-irradiation was examined. It was established that WR-2...
Abstract Background and Objective: The M2 gene expressing the conserved protein in influenza virus can be used to make a single-dose vaccine with permanent immunity. Material and Methods: The mice were allocated to one case group immunized with pcDNA3-M2 and two control groups with pcDNA and PBS, in three dozes with interval of two weeks. Two weeks after the last injection, Cellular imm...
BACKGROUND Many countries, such as Niger, are considering changing their vaccine vial size presentation and may want to evaluate the subsequent impact on their supply chains, the series of steps required to get vaccines from their manufacturers to patients. The measles vaccine is particularly important in Niger, a country prone to measles outbreaks. METHODS We developed a detailed discrete ev...
Previously, we have reported the synthesis of a homochiral l-cyclic peptide [WR]5 and its use for delivery of anti-HIV drugs and biomolecules. A physical mixture of HAuCl4 and the peptide generated peptide-capped gold nanoparticles. Here, [WR]5 and [WR]5-AuNPs were tested for their efficiency to deliver a small interfering RNA molecule (siRNA) in human cervix adenocarcinoma (HeLa) cells. Flow c...
Live recombinants based on attenuated modified vaccinia virus Ankara (MVA) are potential vaccine candidates against a broad spectrum of diseases and tumors. To better understand the efficacy of MVA as a human vaccine, we analyzed by confocal and electron microscopy approaches MVA-induced morphological changes and morphogenetic stages during infection of human HeLa cells in comparison to other s...
Context. The favoured progenitors of long-duration gamma-ray bursts (GRBs) are rapidly rotating Wolf-Rayet (WR) stars. However, most Galactic WR stars are slow rotators, as stellar winds are thought to remove angular momentum. This poses a serious challenge to the collapsar model. Recent observations indicate that GRBs occur predominately in low metallicity (Z) environments, which may resolve t...
Among poliomyelitis eradication activities recommended by WHO are national immunization days. Most campaigns have delivered oral poliovirus vaccine (OPV) from fixed sites, reaching 80-90% of target populations. Although house-to-house vaccination provides nearly universal coverage, countries have been reluctant to use this approach because it is considered more costly and logistically difficult...
Beef cattle production requires reproductive efficiency. However, measures of reproductive traits are not usually collected; consequently, correlated traits that could be used as indicators would be useful. We examined associations between measures of reproductive and productive efficiency that could be used as selection indicators. Data from 194 dams of the genetic groups Angus x Nelore, Carac...
