Abstract: A bone graft composition comprising a viable, osteogenic cellular material combined with a viscous cryoprotectant that includes a penetrating cryoprotective agent and a non-penetrating cryoprotective agent. The viscosity of the cryoprotectant is such that the composition is malleable, cohesive and capable of being formed into desired shapes.

Abstract: The present invention relates to methods of making and using composites and scaffolds as implantable devices useful for tissue repair, guided tissue regeneration, and tissue engineering. In particular, the present invention relates to methods of making and using compression molded resorbable thermoplastic polymer composites which can be subsequently processed with non-organic solvents to create porous, resorbable thermoplastic polymer scaffolds or composite scaffold with interconnected porosity. Furthermore, these composites or scaffolds can be coated with an organic and/or inorganic material.

Abstract: This invention relates, first, to the discovery of IL-17RL, a receptor for members of the IL-17 cytokine family, particularly IL-17B. IL-17RL is naturally expressed from a 19-exon gene as a 720 amino acid protein and as any of 11 splice variants created from differential splicing of the 19 exons. The invention further relates to the discovery that IL-17B is involved in catabolic degradation of bone and cartilage and that bone and cartilage disorders can be ameliorated by pharmacological manipulation of IL-17B by antibodies or by using IL-17RL as a decoy to reduce IL-17B related catabolic activity. Methods for diagnosing cartilage disorders, and pharmaceutical compositions for slowing or ameliorating bone and cartilage pathologies are also provided.

Abstract: The selectivity of response of resistive gas sensors to specific gases or vapors is improved by the selection of specified gas-sensitive materials which are not previously known for the applications described, which include detection of hydrocarbons in the presence of CO, H.sub.2 S, SO.sub.2, chlorine, NO.sub.2, CO.sub.2 (especially in low concentrations), CFC's, ammonia, free oxygen by determination of partial pressures, and numerous organic gases and vapors.

Abstract: A resistive gas sensor having a WO.sub.3 sensing element is especially useful for detection of low concentrations (1 ppm or less) of ozone in air. The WO.sub.3 element is a porous layer with a 30-60% porosity and less than 50 micrometer thick, having in general a sufficiently open porous microstructure and high surface area to give satisfactory response to ozone. The sensor is used for detection of low ozone concentrations at a working temperature in the range from ambient to 600.degree. C.
