  • Publication number: 20240082196
    Abstract: An object of the present disclosure is to provide a more effective therapeutic method in cancer therapy using the tumor immune mechanism. An object of the present disclosure is to provide a drug that enhances the production of antitumor, inflammatory, and anti-inflammatory cytokines as the more effective tumor immune therapy. Alternatively, an object of the present disclosure is to provide a drug that increases tumor-infiltrating lymphocytes as the more effective tumor immune therapy. An antitumor agent to be administered in combination with an anti-PD-1 antibody, an anti-PD-L1 antibody, and/or an anti-CTLA-4 antibody, which are immune checkpoint inhibitors (ICIs), comprising: ubenimex as an active ingredient. The combination therapy of ubenimex and an ICI improves the tumor immune function as compared with the use of each of these alone, and brings many benefits to the treatment of malignant tumors.

  • Publication number: 20200190101
    Abstract: Provided is a pharmaceutical preparation that is suitable for more effectively exhibiting the efficacy of a glutamic acid derivative, which is a GGT-recognizable prodrug, by producing a composition including a glutamic acid derivative capable of rapidly releasing a physiologically active substance by being recognized by GGT, or a pharmacologically acceptable salt thereof; and a block copolymer in which a polyethylene glycol segment is linked to a polyamino acid segment with a hydrophobic group. Particularly, the composition based on a glutamic acid derivative that uses an antitumor compound as a physiologically active substance is capable of effectively accumulating the glutamic acid derivative at a tumor affected area, exhibits a superior effect against tumors, and is capable of suppressing the release of a physiologically active substance in bone marrow tissue where the expression ratio of GGT is low.

  • Patent number: 8993100
    Abstract: An infrared ray reflection pattern-printed transparent sheet is provided which can be applied to a data input system of a type of handwriting directly on a screen of a display device and provides a coordinate detect means and which is lightweight, low in a cost, readily increased in an area, possible in mass production and excellent in a read performance. It is an infrared ray reflection pattern-printed transparent sheet in which infrared ray reflective transparent patterns are printed on a surface of a transparent substrate and which is disposed oppositely to a front face of a display device. A cross section obtained by cutting the infrared ray reflective transparent patterns printed on the above transparent substrate in a face orthogonal to the above transparent substrate is formed so that it assumes a multilayer structure comprising a fixed repeating cycle when observed under a scanning electron microscope.

  • Patent number: 8523237
    Abstract: Provided is a reflected pattern-printed transparent sheet in which a high reflection intensity of a non-visible light is obtained and in which a transparency in a visible light region is high. The above transparent sheet is a reflected pattern-printed transparent sheet in which non-visible light reflective transparent patterns are printed on a surface of a transparent substrate and which is mounted oppositely to a front face of a medium capable of displaying images, wherein an ink forming the transparent patterns described above contains a non-visible light reflection material; the non-visible light reflection material is a material having a wavelength selection reflectivity to a wavelength in a non-visible light region; and a thickness of the above transparent patterns is 6 to 20 ?m.

  • Publication number: 20060176533
    Abstract: The invention provides a hologram plate which is used with the double-focus replication process, and which is integrated with a spacer to impart marring resistance thereto, and is integrated with a light absorbing layer to allow zero-order light and first-order light to have substantially the same intensity. This hologram plate 42 comprises an array of collective element holograms for diffracting parallel light incident thereon at a specific wavelength and a specific incident angle in such a way that the light is converged onto a specific focal length position. The hologram plate 42 is a multilayer structure made up of a first transparent substrate 31, a hologram layer 32, an adhesive layer 33 and a second transparent substrate 41. The second transparent substrate 42 defines a surface in contact with a hologram photosensitive material 53 during hologram replication.
