| 20110005379 | Flexible spike and ballistic resistant panel - A flexible spike and ballistics panel having a strike surface and a rear surface. The panel contains a strike face grouping and a rear face grouping, where the normalized stiffness of each strike face layer is about 3 to 50 times greater than the normalized stiffness of each textile layer. The strike face grouping contains at least two strike face layers, each strike face layer having resin and high tenacity yarns, where the high tenacity yarns are in an amount of at least 50% by weight in each layer, where the high tenacity yarns have a tenacity of at least 5 grams per denier, and where the strike face grouping forms the strike surface of the panel. The rear face grouping contains at least ten layers of a spike resistant textile layer, each textile layer having a plurality of interwoven yarns or fibers having a tenacity of about 5 or more grams per denier, where at least one of the surfaces of the spike resistant textile layer contains about 10 wt. % or less, based on the total weight of the textile layer, of a coating comprising a plurality of particles having a diameter of about 20 μm or less. | 01-13-2011 |

| 20100316667 | GENETICALLY STABLE RECOMBINANT MODIFIED VACCINIA ANKARA (RMVA) VACCINES AND METHODS OF PREPARATION THEREOF - A vaccine comprising an immunologically effective amount of recombinant modified vaccinia Ankara (rMVA) virus which is genetically stable after serial passage and produced by a) constructing a transfer plasmid vector comprising a modified H5 (mH5) promoter operably linked to a DNA sequence encoding a heterologous foreign protein antigen, wherein the expression of said DNA sequence is under the control of the mH5 promoter; b) generating rMVA virus by transfecting one or more plasmid vectors obtained from step a) into wild type MVA virus; c) identifying rMVA virus expressing one or more heterologous foreign protein antigens using one or more selection methods for serial passage; d) conducting serial passage; e) expanding an rMVA virus strain identified by step d); and f) purifying the rMVA viruses from step e) to form the vaccine. One embodiment is directed to a fusion cytomegalovirus (CMV) protein antigen comprising a nucleotide sequence encoding two or more antigenic portions of Immediate-Early Gene-1 or Immediate-Early Gene-2 (IEfusion), wherein the antigenic portions elicit an immune response when expressed by a vaccine. | 12-16-2010 |
