A pharmaceutically acceptable composition comprising trehalose and a pharmaceutically acceptable excipient and methods of delivering autophagy stimulating trehalose to a patient in need thereof.

Formulations for the delivery of autophagy stimulating trehalose

A light modulating device such as a liquid crystal display or polarizer is fabricated using optically biaxial plastic material as a substrate. The plastic biaxial material replaces the glass substrate of the LCD, or the cellulose acetate butyrate (CAB) of the polarizer. The biaxial material is a type of stretched plastic, which is more flexible than glass, and much thinner in typical display applications. Typical plastic biaxial materials are chemically stable with liquid crystals and much more stable than isotropic plastics (CAB). The material is optically anistropic, but optical axes of the material are chosen to be outside the field of view over which the device will be observed.

Biaxial substrates in light modulating devices

A twisted nematic liquid crystal material is sandwiched between two electrode carrying polymer film or sheet substrates in a liquid crystal display assembly. The substrate material preferably is a semi-crystalline aromatic heterochain polymer characterized by a glass transition point (T.sub.g) of at least 90.degree. C. and devoid of secondary transitions in the -50.degree. C. to +80.degree. C. range. The crystallinity of the polymer material is controlled so that the crystallite size in the polymer material is substantially smaller than the wave length of visible light (350-750 micrometers). In a preferred embodiment, an optically isotropic top substrate is formed by a sheet of amorphous cast thermosetting acrylic resin and the lower substrate is formed by a flexible sheet of semi-crystalline aromatic heterochain polymer.
