Biodegradable polymeric microparticle compositions containing one or more active agents, especially those useful for treating or preventing or one or more diseases or disorders of the eye, and methods of making and using thereof, are described. The microsphere compositions release an effective amount of the one or more active agents for a period greater than 14 days in vivo, preferably greater than 60 days in vivo, more preferably up to 73 days in vivo, more preferably greater than 90 days in vivo, even more preferably over 100 days in vivo, and most preferably greater than 107 days in vivo. In a preferred embodiment, the microparticle compositions contain one or more active agents such as AG1478 to induce nerve regeneration, specifically regeneration of the optic nerve useful for managing elevated intraocular pressure (TOP) in the eye.

A hybrid optoelectronic device and method of producing the hybrid device in which the hybrid device includes a substrate with an input region configured to accept input light, a sol-gel glass multimode interference region coupled to and contiguous with the input region and configured to accept and replicate the input light as multiple self-images, and a sol-gel glass output region contiguous with the multimode region and configured to accept and to output the multiple self-images. Alternatively, the hybrid optoelectronic device includes a substrate with a photoelectronic device, a surface resonator including a light-emitting part of the photelectronic device and configured to resonate light from the photoelectronic device to produce a laser light, and a grating outcoupler contiguous with the surface resonator and configured to diffract the laser light outward from the grating outcoupler and to electrically vary an index of refraction of the outcoupler and change a direction of the diffracted laser light.

Biodegradable polymeric microparticle compositions containing one or more active agents, especially those useful for treating or preventing or one or more diseases or disorders of the eye, and methods of making and using thereof, are described. The microsphere compositions release an effective amount of the one or more active agents for a period greater than 14 days in vivo, preferably greater than 60 days in vivo, more preferably up to 73 days in vivo, more preferably greater than 90 days in vivo, even more preferably over 100 days in vivo, and most preferably greater than 107 days in vivo. In a preferred embodiment, the microparticle compositions contain one or more active agents useful for managing elevated intraocular pressure (TOP) in the eye. In one embodiment, the microspheres are formed from polylactide-co-glycolide (“PLGA”); in another embodiment, the microspheres are formed from a blend PLGA and poly lactic acid (“PLA”). Relatively hydrophilic, and preferably carboxylated, polymeric materials such as PLGA are used for a drug such as timolol maleate, which is relatively water soluble, to increase drug loading. Higher molecular weight polymers, as well as the ratio of LA (which has a longer degradation time, up to one to two years) to GA (which has a short degradation time, as short as a few days to a week), are used to provide release over a longer period of time. The combination of drug loading and release rate, as well as the minimization of initial burst release, result in prolonged release of a higher amount of drug.

A system, including a particulate matter analyzer and collecting filter, provides a method of analyzing and collecting samples from fluids, such as collecting particulate matter from air. A mass measuring unit and composition analyzing unit can be provided for either simultaneous or immediately consecutive measurements within a single instrument. The filter material can have an antistatic electricity characteristic and can be impregnated with reference material to enable calibration of the composition analyzing unit.

An elongate batten (1) adapted for positioning intermediate an inner wall framing member (2) and an outer wall cladding sheet (3) to facilitate dispersion and evaporation of moisture from a wall cavity. The batten includes at least one channel to facilitate migration and drainage of moisture between the batten and the framing member.

An imaging tube (12) includes a cathode (30) that emits an electron beam (32) and an anode (38). The anode (38) includes multiple target surfaces (36). Each of the target surfaces (36) has a focal spot that receives the electron beam (32). The target surfaces (36) generate multiple x-ray beams (42) in response to the electron beam (32). Each x-ray beam (42) is associated with one of the target surfaces (36). An x-ray imaging system (10) includes the cathode (30) and the anode (38). A controller (28) is electrically coupled to the cathode (30) and adjusts emission of the electron beam (32) on the anode (38).

The present invention provides a method of minimizing absorption of visible light in an ink composition comprising an IR-absorbing macrocyclic cyanine dye, comprising preselecting said dye such that it includes at least one moiety for reducing intermolecular interactions between adjacent dye molecules.

R¹, R² and R⁵ are H or CH₃, R³ and R⁴ are H or OH, and X is a tertiary alkyl group having an adamantane structure. A resist composition comprising the inventive polymer has a sensitivity to high-energy radiation, improved resolution and minimized proximity bias and lends itself to micropatterning with electron beams or deep UV for VLSI fabrication.

A panel light source device comprises a light source, a U-shaped reflector surrounding the light source, a light guide, and a plurality of metal grid wires. The light guide has an incoming surface facing the light source and an outgoing surface. The light is transmitted into the light guide from the incoming surface and then transmitted out of the light guide from the outgoing surface. The metal grid wires are disposed between the incoming surface and the light source for transmitting the light with a predetermined polarization therethrough and reflecting the rest light therefrom.
