    Abstract: Dry cross-linked gelatin compositions are prepared that rapidly re-hydrate to produce gelatin hydrogels suitable as hemostatic sealants. Gelatin is cross-linked in the presence of certain re-hydration aids, such as polyethylene glycol, polyvinylprovidone, and dextran, in order to produce a dry cross-linked gelatin powder. The use of the re-hydration aids has been found to substantially increase the re-hydration rate in the presence of an aqueous re-hydration medium, typically thrombin-containing saline.

  • Publication number: 20080248098
    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.

  • Publication number: 20080199531
    Abstract: This invention is predicated on the present applicants' discovery that nanostructures comprising discrete regions of different composition can be used to deliver to a biological cell a desired combination of molecules in close proximity. Different molecules can be selectively bonded to discrete regions of different composition in sufficiently close physical relationship to enhance delivery or effectiveness within the cell. The preferred nanostructures are multicomponent nanorods. Important applications include delivery of missing DNA sequences for gene therapy and delivery of antigens or DNA encoding antigens for vaccination.

  • Publication number: 20080193547
    Abstract: The present invention relates to biocompatible and biodegradable, stimuli sensitive, polymeric nanoparticles, which are formed by ion-ion interaction in aqueous media. Synthetic and biological macromolecules with ionizable functional groups are capable of forming nanoparticles whose size and surface properties are sensitive to environmental factors such as pH, temperature and salt concentration. Nanodevices made from these nanoparticles are designed for therapeutic applications included but not limited to use as drug carriers and/or used as contrast agents in MRI diagnosis and the like. The adjustable size of the nanodevices and their stimuli sensitivity allows specific delivery applications. Thus, these nanosystems are potential carrier tools for delivery of active ingredients such as drugs, as well as DNA, RNA, siRNA for cosmetics, pharmaceutical applications, etc.

  • Publication number: 20080175904
    Abstract: The present invention relates to a particulate material and a solid dosage form notably tablets comprising a regularly shaped calcium-containing compound such as a calcium salt as a therapeutically and/or prophylactically active substance and a pharmaceutically acceptable sugar alcohol such as, e.g., sorbitol and/or isomalt that has a micro structure as evidenced by SEM. The invention also relates to a process for the preparation of the particulate material and solid dosage form. The process involves agglomeration of the calcium-containing compound and the pharmaceutically acceptable sugar alcohol by means of roller compaction. The particulate material obtained by roller compaction is suitable for use in the further processing of the particulate material into e.g. tablets such as chewing tablets.
