    Abstract: An antipathogenic biomedical implant is formed throughout its structure of a matrix material comprising at least about 1 weight percent of a photocatalytically active filler which exhibits an antipathogenic effect upon irradiation with light. The photocatalytically active filler is arranged in the matrix material in the implant to receive light irradiated from an external light source. In another embodiment, an antipathogenic biomedical implant comprises at least about 1 weight percent of a photocatalytically active material which exhibits an antipathogenic effect upon irradiation with light, wherein the photocatalytically active material is arranged in the implant to receive light irradiated from an external light source. Methods for providing an antipathogenic biomedical implant, methods for reducing pathogens on a biomedical implant, methods for reducing the bioburden in a biomedical implant installation, and kits for providing an antipathogenic biomedical implant employ the antipathogenic biomedical implants.

    Abstract: Refrigerated hydraulic cement compositions comprise a mixture of (a) β-tricalcium phosphate powder, (b) monocalcium phosphate comprising monocalcium phosphate anhydrous (MCPA), monocalcium phosphate monohydrate (MCPM), or a combination thereof, wherein a 0.1 g/ml saturated aqueous solution of the monocalcium phosphate has a p H less than 3.0, (c) non-aqueous water-miscible liquid, and (d) an aqueous hydrating liquid. The aqueous hydrating liquid is included in an amount of about 1-50 volume percent, based on the combined volume of the non-aqueous water-miscible liquid and the aqueous hydration liquid, and the refrigerated hydraulic cement composition is storage stable for greater than one day, without setting. Methods of forming hardened cements in vivo and/or for forming implants for use in vivo employ the hydraulic cement compositions.

    Abstract: A meit-extruded substrate (e.g., fiim, nonwoven web, etc.) that contains a thermoplastic starch formed from a starch and plasticizer is provided. The starch and plasticizer are melt blended together in the presence of a weak organic acid (e.g., lactic acid, formic acid, acetic acid, etc.). By selectively controlling certain parameters of the melt blending process (e.g., extrusion temperature, content of the components, etc.), the present inventors have discovered that the starch may be hydrolyzed in a highly efficient manner to form compositions having a comparably lower weight average molecular weight, polydispersity index, and viscosity, which are particularly suitable for use in the formation of melt-extruded substrates.
