  • Patent number: 11946086
    Abstract: This invention is intended to identify a gene cluster involved in biosynthesis of a cyclic peptide compound produced by a filamentous fungus of the Curvularia species and to establish a system for synthesizing such cyclic peptide compound. The gene is composed of a first module to a tenth module and encodes a protein having activity of synthesizing a nonribosomal peptide constituting a basic peptide backbone of a cyclic peptide compound produced by a filamentous fungus of the Curvularia species.

  • Patent number: 11021725
    Abstract: Provided is a mutant filamentous fungus, which lacks expression of ?-1,3-glucan, and is deficient in at least part of a GAG biosynthetic cluster. Also provided is a method of producing a substance, including the steps of: culturing the filamentous fungus to allow the filamentous fungus to produce a substance; and collecting the resulting substance.

  • Publication number: 20150260729
    Abstract: The object is to provide a combination of biomarkers which allow highly accurate discrimination of schizophrenia, and a utilization thereof. A combination of schizophrenia marker set including a combination of two or more protein molecules selected from the group consisting of trifunctional purine biosynthetic protein adenosine-3, uroporphyrinogen decarboxylase, interferon-induced GTP-binding protein Mx1, glutaredoxin-3, microtubule-associated protein RP/EB family member 1, tubulin folding cofactor B, immunoglobulin mu chain C region, and heat shock 70 kDa protein 4L is provided. In addition, a method for examining schizophrenia using the level of the marker set in a specimen as an index is provided.

  • Publication number: 20060257760
    Abstract: The near-infrared ray absorption film of the present invention is a near-infrared ray absorption film in which a near-infrared ray absorption layer comprising a composition containing a near-infrared ray absorbing dye having maximum absorption at a wavelength of 800 to 1200 nm, and a resin is provided on a transparent substrate film, and is characterized that a surfactant having HLB of 2 to 12 is contained in the composition at 0.01 to 2.0% by mass. There can be provided a near-infrared ray absorption film excellent in coated film appearance which has the wide absorbing ability in the near-infrared ray absorbing region, has a high light transmittance in the visible light region, has little change in optical properties with time, and can respond to a higher luminance of a display, and higher-definition and higher image quality by Hi-Vision broadcasting in recent years.

  • Publication number: 20020106512
    Abstract: Magnetite particles having high electric charge, low stirring torque and low adsorbed moisture content as compared with conventional magnetite particles for magnetic toners are prepared. The process comprises slurrying wet-synthesized magnetite particles, then adjusting the pH successively with a given amount of a water-soluble aluminium salt and a given amount of colloidal silica. Optionally, the particles are further covered with a silicone oil and/or coupling agent. Then, filtration, washing and drying take place.

  • Patent number: 5959685
    Abstract: According to this character display apparatus, a limit of a frequency band of a character display signal is removed and small characters, etc., also can be displayed satisfactorily. A sync signal from a sync separating circuit (4) is supplied to a character generating circuit (8) in which a display signal of arbitrary characters or the like is formed by RGB three primary color signals in synchronism with predetermined dot clocks. The thus formed display signal is supplied to a line memory (9) and dot clocks are supplied to the line memory (9) and thereby the display signal is written in the line memory (9). Further, dot clocks are supplied to a multiplying circuit (10) and clock multiplied with an arbitrary multiplying ratio are supplied to the line memory (9) so that the written display signal is read out from the line memory (9).
