Abstract: Provided is an orthopedic implant comprising a surface with a coating on the surface wherein the coating comprises a copolymer defined by Formula I: Aw-Bx-Cy-Dz wherein: A comprises an epoxy group; B comprises a hydrophobic group; C is an optional cross-linker; D of Formula I comprises a hydrophilic group; w is at least 0.1 to no more than 0.9 with the proviso that at least one of x or z is not zero; x is up to 0.9; y is up to 0.3; and z is up to 0.9.

Abstract: This invention is directed to the application of a previously unknown property of nanomaterials—its ability to enhance protein activity and stability at high temperatures, in organic solvents, and in polymer composites. Nanomaterials such as single-walled carbon nanotubes (SWNTs) can significantly enhance enzyme function and stability in strongly denaturing environments. Experimental results and theoretical analysis reveal that the enhancement in stability is a result of the curvature of these nanoscale materials, which suppresses unfavorable protein-protein interactions.

Abstract: Disclosed is a process for extracting an antioxidant cocktail (containing a number of antioxidative molecules including but not limited to superoxide dismutase (SOD), catalase, glutathione, glutathione peroxidase) from animal sources (i.e., blood or liver) so that it can be used as a food and feed preservative in a non-purified state to prevent rancidity. The antioxidant can also be used in other products such as oils, paint, caulking, plastics, or any other product exposed to oxidation. The disclosed antioxidant cocktail can be used in an unpurified state, yet can still function as a potent antioxidant without having to undergo purification via complex, expensive methods such as chromatography or gel filtration.

Abstract: Disclosed are devices as may be used to deliver a fibrinolytic agent such as functional tPA to targeted sites. Disclosed devices include micro or nanosized particles as carriers of a fibrinolytic agent and a targeting polypeptide such as antifibrin antibody that specifically binds a component of a blood clot. A plurality of protein molecules can be bound to a single particle. In addition, the total number of protein molecules attached to each particle can be controlled as can the proportion of each different compound bound to a single particle. Disclosed devices can be utilized, for example, to deliver tPA to blood clots, for instance in postmyocardial infarction or ischemic stroke treatment, and can minimize systemic plasminemia compared to the use of free tPA.

Abstract: Thermally stable transitional alumina particulates retaining high specific surface area after calcination at 1000° C. suitable for the use as catalysts or catalysts supports are produced by treating an aqueous solution containing Al3+ and optionally a doping amount of La3+ (e.g., 0.3 mol. %) with an anion-exchange resin to give a stable hydroxide sol followed by freeze drying of the sol and further thermal dehydration. The resultant stabilized transitional alumina retains high specific surface area at 1000° C., and additionally stabilization is achieved at very low levels of added La.
