  • Publication number: 20070164308
    Abstract: A light emitting apparatus has a light emitting element with an emission wavelength in the range of 360 to 550 nm and a rare-earth element doped oxide nitride phosphor or cerium ion doped lanthanum silicon nitride phosphor. Part of light radiated from the light emitting element is wavelength-converted by the phosphor. The light emitting apparatus radiates white light generated by a mixture of the wavelength-converted light and the other part of light radiated from the light emitting element.

  • Publication number: 20070122466
    Abstract: The present invention provides pharmaceutical compositions and methods for the instillation of lipid vehicles comprised of liposomes containing sphingomyelin or sphingomyelin metabolites to prevent, manage, ameliorate and/or treat disorders involving neuropathic pain and aberrant muscle contractions, such as what occurs in bladder hyperactivity disorders such as interstitial cystitis (IC) in animals or humans in need thereof. Also provided is a liposome-based delivery of drugs, e.g., antibiotics, pain treatments and anticancer agents, to the bladder, genitourinary tract, gastrointestinal system, pulmonary system and other organs or body systems. In particular, liposome-based delivery of vanilloid compounds, such as resiniferatoxin, capsaicin, or tinyatoxin and toxins, such as botulinum toxin is provided for the treatment of bladder conditions, including pain, inflammation, incontinence and voiding dysftunction.

  • Publication number: 20070003610
    Abstract: The present invention relates to compositions and methods for the administration of lipid-based vehicles to treat various disorders, including bladder inflammation, infection, dysfunction, and cancer. In various aspects, the compositions and methods of the invention are useful for prolonged delivery of drugs, e.g., antibiotics, pain treatments, and anticancer agents, to the bladder, genitourinary tract, gastrointestinal system, pulmonary system, and other organs or body systems. In particular, the present invention relates to liposome-based delivery of vanilloid compounds, such as resiniferatoxin, capsaicin, or tinyatoxin, and toxins, such as botulinum toxin, for the treatment of bladder conditions, including pain, inflammation, incontinence, and voiding dysfunction. Further related are methods of using these vehicles alone or in conjunction with antibodies, e.g., uroplakin antibodies, to improve duration of liposome attachment, and provide a long-term intravesical drug delivery platform.

  • Publication number: 20020114601
    Abstract: An optical fiber, a mixture solution of the photosetting resins polymerizing in two different polymerization types, and a transparent container are prepared. The photosetting resins are not copolymerized, and have different activation wavelengths of the photopolymerization initiators for hardening. Employing a combination in which the activation wavelength of a photopolymerization initiator for a photosetting resin with higher refractive index after hardening is longer than the activation wavelength of a photopolymerization initiator for a photosetting resin with lower refractive index after hardening, a core portion can be only formed by hardening the photosetting resin with higher refractive index due to a difference between two wavelengths. Thereafter, a clad portion can be formed by hardening two kinds of photosetting resins, where by an optical transmission device can be manufactured.

  • Patent number: 4322327
    Abstract: A novel slow-curing water-curable urethane prepolymer composition obtained by reacting (A) a hydrophilic urethane prepolymer which is a reaction product of a polyisocyanate and a hydrophilic polyol prepolymer and has at least two --NCO groups and (B) a blocking agent selected from a class consisting of heterocyclic compounds having an ##STR1## structure in the molecule thereof, hydroxypyridines and hydroxyquinolines in the proportion that the equivalent ratio of the .dbd.NH groups of the --OH groups in the blocking agent (B) to the --NCO groups in the hydrophilic urethane prepolymer (A), that is, --OH or .dbd.NH/--NCO ratio, is 0.05 to 2 is disclosed. This composition is remarkably useful as a grouting material, for forming hydrogel which is effective as a fixative or carrier of various materials, as a vehicle for coating materials, and as a stabilizer and thickener for aqueous resin emulsions.
