  • Patent number: 8591951
    Abstract: Biocompatible non-toxic triblock copolymers having an A-B-A structure wherein each A is a hydrophilic, biocompatible end block and the B middle block is a hydrophobic desaminotyrosyl tyrosine polycarbonate or polyarylate. The copolymers spontaneously self-assemble to form low critical aggregation concentration nanospheres having utility as delivery vehicles for hydrophobic biologically or pharmaceutically active compounds.

  • Patent number: 8586084
    Abstract: A modified release composition comprising tacrolimus releases less than 20% w/w of the active ingredient within 0.5 hours when subjected to an in vitro dissolution test using USP Paddle method and using 0.1 N HCl as dissolution medium and has increased bioavailability by effectively reducing or even avoiding the effects of CYP3A4 metabolism. The modified composition may be coated with an enteric coating; and/or may comprise a solid dispersion or a solid solution of tacrolimus in a hydrophilic or water-miscible vehicle and one or more modifying release agents; and/or may comprise a solid dispersion or a solid solution of tacrolimus in an amphiphilic or hydrophobic vehicle and optionally one or more modifying release agents.

  • Patent number: 8586089
    Abstract: Improved compositions for tissue augmentation are provided. These compositions comprise an amount of crosslinked material sufficient to provide a melt temperature (Tm) greater than 37C, wherein microparticles can be substantially uniformly dispersed and maintained at ambient room temperature as well as body temperature. Said compositions also provide high shear moduli, sufficient to effectively deliver microparticles into dense tissue and narrow intersticial spaces without significant disruption to the homogeneous distribution of microparticles within the solution. The provided compositions can be stored and shipped at room temperature without significant detriment to the material composition. Additional embodiments include a system for delivery of tissue augmentation materials and methods of manufacture thereof.

  • Patent number: 8574461
    Abstract: A method of manufacturing a biopolymer optical device includes providing a polymer, providing a substrate, casting the polymer on the substrate, and enzymatically polymerizing an organic compound to generate a conducting polymer between the provided polymer and the substrate. The polymer may be a biopolymer such as silk and may be modified using organic compounds such as tyrosines to provide a molecular-level interface between the provided bulk biopolymer of the biopolymer optical device and a substrate or other conducting layer via a tyrosine-enzyme polymerization. The enzymatically polymerizing may include catalyzing the organic compound with peroxidase enzyme reactions. The result is a carbon-carbon conjugated backbone that provides polymeric “wires” for use in polymer and biopolymer optical devices. An all organic biopolymer electroactive material is thereby provided that provides optical functions and features.
