Abstract: An injection for injecting at least one material into human keratinous materials that includes at least one treatment unit defining at least one cavity and at least one micro-implant made of said at least one material received in said cavity of the unit and having at least one portion having a same shape as the cavity; an injection device configured for applying a pressure to the at least one micro-implant to expel the latter out of the unit into the keratinous materials.

Abstract: The present invention is directed to a cell delivery system for the delivery of materials including nucleic acids across a biological barrier and methods of use thereof. The cell delivery system of the invention comprises a microprotrusion array composed of a swellable and/or dissolvable polymer composition for use in the transport of a material across a biological barrier, wherein the material comprises nanoparticles formed from a nucleic acid complexed with an amphipathic cell penetrating peptide and wherein the microprotrusion array is loaded with the nanoparticles.

Abstract: The invention relates to peptides which, in some embodiments, bind to human FcRn and inhibit binding of the Fc portion of an IgG to an FcRn, thereby modulating serum IgG levels. The disclosed compositions and methods may be used in some embodiments, for example, in treating autoimmune diseases and inflammatory disorders. The invention also relates, in further embodiments, to methods of using and methods of making the peptides of the invention.

Abstract: Polymers with improved bioadhesive properties and methods for improving bioadhesion of polymers have been developed. A compound containing an aromatic group which contains one or more hydroxyl groups is grafted onto a polymer or coupled to individual monomers. In one embodiment, the polymer is a biodegradable polymer. In another embodiment, the monomers may be polymerized to form any type of polymer, including biodegradable and non-biodegradable polymers. In some embodiments, the polymer is a hydrophobic polymer. In the preferred embodiment, the aromatic compound is catechol or a derivative thereof and the polymer contains reactive functional groups. In the most preferred embodiment, the polymer is a polyanhydride and the aromatic compound is the catechol derivative, DOPA. These materials display bioadhesive properties superior to conventional bioadhesives used in therapeutic and diagnostic applications.
