Heat sealable, flame and abrasion resistant coated fabric

Flame retardant, abrasion resistant elastomeric compositions are comprised of thermoplastic polyurethane polymer and flame retarding amounts of a filler selected from decabromodiphenyloxide and antimony oxide in a 3:1 weight ratio, and decabromodiphenyloxide, antimony oxide, and ammonium polyphosphate in a 3:1:3 weight ratio respectively. Coated fabrics employing such elastomeric compositions as coating film are flexible, lightweight, and air impermeable and can be made using heat or dielectric sealing procedures

Heat resistant protective hand covering

The heat resistant, protective glove is made up of first and second shell sections which define a palm side and a backside, respectively. The first shell section is made of a twill wave fabric of a temperature-resistant aromatic polyamide fiber. The second shell section is made of a knitted fabric of a temperature-resistant aromatic polyamide fiber. The first and second shell sections are secured to one another, e.g., by sewing, to provide the desired glove configuration and an opening for insertion of the wearer's hand. The protective glove also includes a first liner section which is secured to and overlies the inner surface of the first shell section and is made of a felt fabric of a temperature-resistant aromatic polyamide fiber and has a flame resistant, elastomenic coating on the surface facing and overlying the inner surface of the first shell section

An AAVP-based solid-phase transducing matrix for transgene delivery: potential for translational applications

A hybrid vector of adeno-associated virus and phage (termed AAVP) has been introduced as a platform for systemic ligand-directed delivery of transgenes to tumors over the past decade. A series of studies have evaluated the AAVP platform for potential theranostic or purely therapeutic applications in several tumor models. Sufficient ligand-directed tumor targeting consistently resulted in specific molecular-genetic imaging and/or anti-tumor responses to ‘suicide’ transgene delivery. However, efforts to optimize transduction efficiency are still ongoing. Here, we set out to expand the translational utility of AAVP by combining it with gold (Au) nanoparticles in order to generate a ‘transducing matrix’ for improved targeted gene delivery in solid phase. Targeted AAVP-based solid-phase transduction is superior to conventional transduction in soluble (aqueous) environments. This transducing matrix is stable and can be further modified with additional attributes (for example, magnetization) for targeted imaging and therapeutic gene delivery. Notably, it spontaneously assembles around cells in vitro to markedly enhance transduction capabilities compared with AAVP alone. This versatile nanoplatform may enable new applications of AAVP for transgene delivery in translational settings including, for example, efforts toward complex tissue patterning
