Abstract: Compositions and methods related to powdered hemostats that crosslink during and/or after application to a bleeding site are described. The compositions may comprise a first component comprising a multifunctionalized polymeric composition (e.g., multifunctionalized polyethylene glycol) functionalized with electrophilic reactive groups, and a second component that comprises a protein such as albumin. The compositions may in certain applications act as hemostats when applied in dry powder form to a bleeding wound, whereupon the first component and the second component of the composition crosslink to form a hydrogel.

Abstract: Methods, compositions, and kits for adhering polymers and other materials to another material, and in particular to bone or bone-like structures or surfaces. A composition of matter includes a urethane dimethacrylate-methyl methacrylate copolymer with a plurality of first polymer regions based on urethane dimethacrylate and a plurality of second polymer regions based on methyl methacrylate. The method includes placing an orthopedic joint implant having an attachment surface in a joint space, applying a first non-urethane-containing precursor, a second urethane-containing precursor, and a initiator to the attachment surface; contacting the first and second precursors and the initiator with the joint surface; and copolymerizing the first and second precursors and forming an adhesive copolymer and attaching the implant to the joint.

Abstract: Provided are a method for producing a cellulose complex capable of substantially uniformly dispersing cellulose in a resin without adding a compatibilizer (dispersant) while maintaining the properties of cellulose, a method for producing a cellulose complex/resin composition, a cellulose complex, and a cellulose complex/resin composition. The method for producing a cellulose complex includes a mixing step of mixing cellulose having a hydroxy group with a polymer having a reactive group capable of reacting with the hydroxy group and including a nonpolar polymer as a molecular chain, and a step of bonding the hydroxy group and the reactive group.
