  • Publication number: 20180068760
    Abstract: In a compound type conductive wire structure 1, a plurality of wire-stranded portions 3 are provided to constitute main wire-twisted portions 5 embedded in an insulator matrix 2. Each of the wire-stranded portions 3 has a subsidiary wire-stranded portion 4 to serve as a diameter-reduced wire-twisted portion 8. Such is the structure that it enables to provide a flexibility, pliability and high strength with a diameter-increased wire-twisted portion 10, while securing a friction-resistant, vibration-resistant, impact-resistant and yet excellent bending capability. It is possible to prevent the main wire-twisted portions 5 from coming loose when removing a plastic layer coated over the main wire-twisted portion 5. The core wire 9 has a curved surface 9a which partly engages in surface-to-surface contact with the diameter-reduced wire-twisted portion 8. This makes it possible to evenly disperse stresses applied to the curved surface 9a of the core wire 9.

  • Patent number: 8110662
    Abstract: A cDNA fragment participating in the maintenance of smooth muscle differentiation was isolated using a culture system of chicken gizzard smooth muscle cells, the differential display method and the subtracted hybridization method. Using the obtained cDNA sequence as a query, cDNA sequences of Helix Research Institute (Japanese Patent Application No. 2000-118776) were retrieved, and thus, a novel gene “C-NT2RP3001495” was obtained. The protein encoded by this gene has two WW domains that participate in protein interactions in the N-terminal domain. Evidence suggests that this protein binds to other proteins, and thus regulates the intracellular signal transduction, gene expression, and so on, thereby participating in the maintenance of the differentiation of smooth muscle cells. This protein and compounds regulating the expression thereof are markedly useful in developing drugs for various diseases associated with abnormality in the maintenance of smooth muscle cell differentiation.

  • Publication number: 20080171353
    Abstract: The clone PLACE6002312 having a structure characteristic of G protein-coupled receptor was isolated from a human placental full-length cDNA library prepared by the oligo-capping method. Database search revealed that PLACE6002312 had the highest homology to HISTAMINE H2 RECEPTOR. Analysis for the expression of PLACE6002312 gene in human tissues revealed that the gene was expressed in various tissues, such as heart, liver, and ovary. In addition, histamine was found to be one of ligands for PLACE 6002312 by ligand-binding assay. Furthermore, a full-length cDNA for the mouse homolog of PLACE6002312 was isolated and the deduced amino acid sequence was revealed to comprise a structure characteristic of G protein-coupled receptor. PLACE6002312 can be used to screen for agonists and antagonists useful as pharmaceuticals and to diagnose various diseases caused by the abnormal activity or expression of the polypeptide.
