A deformable mirror device comprises a plurality of groups of colored mirrors responsive to electronic signals. Each group of mirrors is coated with a mixture of resist and dye thereby reflecting specified wavelengths of visible light.
摘要:
A deformable mirror device comprises a plurality of groups of colored mirrors responsive to electronic signals. Each group of mirrors is coated with a mixture of resist and dye thereby reflecting specified wavelengths of visible light. A process for manufacturing such a color deformable mirror device ("DMD") includes forming a layer of material on the DMD comprising a resist and a dye and selectively removing portions of the layer of material from the DMD.
摘要:
Compositions and methods are provided for treating joint conditions, such as osteoarthritis and/or the pain associated therewith. The compositions and methods utilize a first component, namely hyaluronic acid (“HA”), in combination with at least one stabilizer. The composition can include a stabilizer that increases the stability and shelf-life of the HA. In another embodiment, the compositions and methods can also include an additional component, such as one or more glycosaminoglycans (“GAG”) or GAG precursors. Examples of GAGs or GAG precursors can include chondroitin sulfate (“CS”), dermatan sulfate, heparin, heparan sulfate, keratan sulfate, and glucosamine (“GlcN”).
摘要:
Devices and methods for delivering a therapeutic agent produced via a genetically-altered chondrocyte are provided. More specifically, the device includes a housing which defines a cell chamber configured to retain a large volume of chondrocytes while selectively releasing therapeutic agents produced via these entrapped cells. In an exemplary embodiment, the cell chamber can be configured such that a portion of cells can be positioned at least about 1.5 mm from an external wall of the device (i.e., about 1.5 mm away from an external nutrient supply). For example, the cell chamber can have a tubular configuration having a length and a diameter wherein each of these dimensions is at least about 3 mm (thereby the central core to the chamber is at least about 1.5 mm from the outer wall of the device).
摘要:
Methods and compositions for producing therapeutic agents using chondrocytes are provided. The genetically engineered chondrocytes can be used to express the therapeutic agent in a subject, including in an environment typically associated with chondrocytes and in an environment not typically associated with chondrocytes.

A dental implant that reduces the potential for stress shielding. The dental implant utilizes an implant body that includes a metallic core and a shell disposed about the metallic core. The shell is made from a material that has a lower modulus of elasticity than the metallic core. The metallic core also is connected to a mounting end to which a prosthetic tooth may ultimately be attached.
