Abstract: The present invention relates to a glass composition formulated to provide the controlled release of certain transition metal ions to regulate the cellular hypoxia pathway and the use of these hypoxia-pathway regulating glasses in medicine and in biomedical research, including in the repair, restoration or regeneration of diseased or damaged tissue.

Abstract: A suspension ceiling panel that includes enhanced durability, sound absorption and increased fire safety qualities. The panel comprises a body substrate including a plurality of apertures. The body is further adapted to be connected to the ceiling grid members. The outer exposed surface of the body substrate is covered by a non-woven fibrous material. Apertures in the body substrate in combination with the non-woven fibrous material on the lower exposed surface of the panel provides the appearance of a traditional acoustical panel but provides desirable sound absorption and fire resistive qualities.
