  • Patent number: 8802773
    Abstract: The present invention is directed compositions for delivery of RNA interference (RNAi) polynucleotides to cells in vivo. The compositions comprise amphipathic membrane active polyamines reversibly modified with enzyme cleavable dipeptide-amidobenzyl-carbonate masking agents. Modification masks membrane activity of the polymer while reversibility provides physiological responsiveness. The reversibly modified polyamines (dynamic polyconjugate or DPC) are further covalently linked to an RNAi polynucleotide or co-administered with a targeted RNAi polynucleotide-targeting molecule conjugate.

  • Patent number: 8788848
    Abstract: The claimed subject matter relates to architectures and/or mechanisms that can facilitate issuing, embedding and verification of an optical DNA (o-DNA) signature. A first mechanism is provided for obtaining a set of manufacturing errors inherent in an optical media instance. These errors can be encoded into the o-DNA that can be cryptographically signed with a private key, then embedded into the source optical media instance. A second mechanism is provided that can decrypt the o-DNA with a public key and compare the authenticated errors to the observed errors to ascertain whether the optical media instance is authentic as opposed to a forgery or counterfeit.

  • Patent number: 8782982
    Abstract: A thermal barrier is formed into a hat-shape by folding sections of an extended length of board formed for assembly and insertion as a barrier to thermal radiation into a space between two joists or studs of a floor, wall, roof, or ceiling of a building for completely covering the space while also covering protruding edges of the joists or studs so as to reduce thermal energy transfer through the joists or studs themselves. A thermal barrier assembly is shown with an outer reflective surface and is also shown for assembly into a form having an inner enclosure for enclosing an inner thermal barrier also having a reflective surface for reducing thermal radiation transfer by reflection and protected from dust by virtue of the enclosure.

  • Patent number: 8640501
    Abstract: A neck ring for molding a glass container neck finish that includes at least one closure attachment feature. The neck ring includes two semi-annular bi-metal neck ring halves, each consisting essentially of a neck ring insert of wear-resistant metal construction, and a neck ring body of heat-conductive metal construction different from said wear-resistant metal construction and formed around said neck ring insert so as to embed it in said neck ring body. Each of said neck ring halves has a glass-contacting cavity face that includes a first surface portion formed by said inserts for molding the at least one closure attachment feature on the neck finish, and a second surface portion formed by said bodies for molding portions of the neck finish excluding the at least one closure attachment feature.

    Abstract: The present invention is directed compositions for targeted delivery of RNA interference (RNAi) polynucleotides to hepatocytes in vivo. Targeted RNAi polynucleotides are administered together with co-targeted melittin delivery peptides. Delivery peptides provide membrane penetration function for movement of the RNAi polynucleotides from outside the cell to inside the cell. Reversible modification provides physiological responsiveness to the delivery peptides.

  • Publication number: 20130133277
    Abstract: An insulating panel to be used in a panelized insulation system for insulating and finishing walls, including basement walls has a foam core made of inorganic materials. The system incorporates a capillary break, an integrated water drainage system and an electrical wire chase system within an insulating wall panel. Vertical slots are provided for insertion of metal studs for use in attaching the interior finish panel, such as inorganic fiber cement board with a vinyl laminate finish, onto the insulating panels. Embedding metal studs in the panel core reduces the sound transmission though the panel and eliminates thermal bridging between warm and cold surfaces. Steps on the edges and the top/bottom surfaces of the insulating panel allow more panels to join together with shiplap joints.
