    摘要: An object of the present invention is to provide a sustained drug release system useful for treating eye diseases. There is provided a device for sustained release of an ophthalmic drug, comprising a drug enclosing part and an intraocular retention gas enclosing part adjacent to the drug enclosing part, the enclosing parts being provided in a hollow container having at least one opening part, wherein the drug enclosing part is isolated from the opening part by the intervention of the intraocular retention gas enclosing part.

    摘要: This invention provides a composition and a method for treating or preventing a subject having a tumor that more highly expresses a TUG1 gene than in normal tissues (e.g., brain tumor, breast cancer, colon cancer, prostate cancer, liver cancer, lung cancer, leukemia, or lymphoma), which composition comprises, as an active ingredient, a nucleic acid that inhibits the high expression of the TUG1 gene in tumor stem cells.

    摘要: It becomes possible to stably deliver an inhaled particulate medicine to a targeted part for administration while reducing burdens on a patient. When supplying the particulate medicine into a body by an airflow, a multi-layer flow composed of a core airflow (A) and a clad airflow (B) outside the core airflow is used as the airflow. The medicine is dispersed in the core airflow (A) and velocity of the clad airflow (B) is set higher than that of the core airflow (A). The medicine dispersed in the core airflow (A) reaches the targeted part for administration while the medicine is protected by the clad airflow (B) without contacting a larynx and the like. A cross-sectional area of the airflow is set smaller than that of the larynx. The airflow is supplied to an upper side of the larynx.

    摘要: Provided is a process for producing colloidal crystals from which a large single crystal reduced in lattice defects and unevenness can be easily produced at low cost without fail. The process for colloidal crystal production comprises: preparing a colloidal polycrystal dispersion in which colloidal crystals precipitate at a given temperature (preparation step); introducing into a vessel The colloidal polycrystal dispersion in the state of containing fine colloidal polycrystals precipitated (introduction step); and melting the colloidal polycrystals and then recrystallizing the molten polycrystals (recrystallization step). The crystals thus obtained have fewer lattice defects and less unevenness than the original polycrystals.
