  • Patent number: 8932616
    Abstract: Hydrophobic ?(1?4)glucopyranose polymers with enhanced degradation properties are described. Between the ?(1?4)glucopyranose polymeric portion and the hydrophobic portion exists a linker portion having a silyl ether chemistry that facilitates degradation of the polymer. Biodegradable matrices can be formed from these polymers, and the matrices can be used for the preparation of implantable and injectable medical devices wherein the matrix is capable of degrading in vivo at an increased rate. Matrices including and capable of releasing a bioactive agent in vivo are also described.

  • Patent number: 8932633
    Abstract: A method of preparing polysaccharide glassy microparticles which are less than 10 ?um in diameter and contain structurally delicate agents, such as proteins, peptides, gene materials, vaccines, antibodies, viruses and liposomes using low-temperature aqueous-aqueous emulsification (free of polyelectrolytes) and freezing-induced phase separation. When delicate agents are added to a polysaccharide-PEG two phase system followed by homogenization (or other shear adding process), the agents partition into the polysaccharide dispersed phase preferentially. These processes help to avoid aggregation of proteins caused by interaction with charged polyelectrolytes used for stabilizing the polysaccharide dispersed phase in our previously reported aqueous-aqueous emulsion. When this system is frozen and lyophilized, glassy particles less than 10 ?m in diameter containing delicate agents can be formed.

  • Patent number: 8790702
    Abstract: The present application provides compositions comprising hyaluronic acid having low levels of functional group modification, mixtures formed by controlled reaction of such lightly modified hyaluronic acid with suitable difunctional or multi-functional crosslinkers, and hydrogel precursor compositions and the resulting hydrogels. The compositions are lightly cross-linked and possess low pro-inflammatory properties when injected in vivo, and can be used as, for example, medical devices, biomedical adhesives and sealants, and for localized delivery of bioactive agents, among other uses.

  • Patent number: 8790695
    Abstract: A medicinal carrier is provided. The medicinal carrier comprises a first component, which is a biocompatible polymer with an amino group (—NH2); a saccharide; and a second component which is a biocompatible material. The saccharide grafts to the first component via the amino group (—NH2) of the first component, and the first component bonds to the second component via an ionic bond. The medicinal carrier can protect the medicine from gastric acid and swell or decompose to release the medicine under a specific pH condition, thus, showing a good applicability.

  • Patent number: 8778399
    Abstract: Tablets and other objects are film coated by including in the tablet a film-forming polymer that is activated upon contact with an activating amount of liquid. The film-forming polymer, e.g., a cellulosic ether, is homogeneously mixed with the other ingredients of the tablet, shaped into any desirable form, loaded into a conventional coating apparatus, and sprayed or foamed with an activating amount of fluid, e.g., water, alcohol, etc., and dried. This coating process eliminates potential problems such as spray nozzle clogging, inappropriate coating fluid viscosity, and the inability to properly atomize the coating fluid. This coating process does not impart any appreciable weight or thickness gain to the tablet.

  • Patent number: 8778369
    Abstract: Long-lasting persistent, uniform, film-forming skin protecting compositions provide long-lasting persistent barrier films when applied to skin. The compositions have particular utility as barrier teat dips for protecting cows against mastitis and as wound care agents. A barrier film-forming agent is selected from pullulan, pullulan derivatives and combinations thereof. The barrier film-forming agent is stably solubilized in a solvent that dries to form the long-lasting, persistent, uniform film over the animal skin. The compositions may contain additives, such as antimicrobial agents that kill microorganisms.
