Abstract: Disclosed are compositions and kits useful for bone repair and reconstruction of bone defects such as bone voids and fractures. The compositions can include two reactive components that when mixed together form a polythiourethane that cures to a hard solid. Also disclosed are methods of making and using the compositions.

Abstract: A talking greeting card has a front display panel and overlapping rear panels adapted to lie substantially flat in one configuration. The front panel may be bowed in convex shape and held in such second configuration by tabs which secure the rear panels together in tension. A flexible sound record strip extends through a slot in the bowed front panel and has a surface prepared to produce sounds when a sliding element, such as the thumb nail of a user, moves along the surface. The sound is amplified by the bowed front wall and overlapping rear walls which act as a sound amplifier.
