DIAGNOSTIC AGENT AND THERAPEUTIC AGENT FOR DISEASE ASSOCIATED WITH HEPATOCYTE GROWTH FACTOR RECEPTOR
Publication number: 20090169473Abstract: Disclosed is a diagnostic agent which is useful for imaging the site of application at which the highest therapeutic effect is expected (i.e., the site where an HGF receptor is expressed) in the therapy of an ischemic disease with an HGF plasmid for the purpose of promoting the angiogenesis with good efficiency. The diagnostic agent is for a disease associated with a hepatocyte growth factor receptor. wherein the drug includes: a labeled product of a partial polypeptide of hepatocyte growth factor containing a heparin-binding domain; or a labeled product of a polypeptide which consisting of an amino acid sequence in which one or several amino acid residues are substituted, deleted or added to the amino acid sequence of the partial polypeptide and having a heparin-binding activity.Type: ApplicationFiled: October 24, 2006Publication date: July 2, 2009Applicant: FUJIFILM RI PHARMA CO., LTD.Inventors: Tsunehiko Nishimura, Akio Nagano -
Patent number: 4136611Abstract: This invention provides for an improved high speed printer using electrostatic means. The paper used is ordinary paper that is first dried to increase its electrical resistance. The electrostatic image is produced directly on the ordinary paper and then the electrostatic image is developed and fixed thereon. The invention includes details of the heating means.Type: GrantFiled: June 22, 1977Date of Patent: January 30, 1979Assignee: Oki Electric Industry Co., Ltd.Inventors: Akinori Watanabe, Akio Nagano, Katsuhide Tanoshima

Patent number: 3967143Abstract: The ultrasonic wave generator of the present invention always drives a transducer with the resonant frequency f.sub.o of the transducer. Although the resonant frequency f.sub.o changes due to the temperature change etc., the driving frequency automatically follows the change of the resonant frequency f.sub.o. The control of the driving frequency is performed by means of a feed-back loop including a voltage controlled oscillator and means for applying a control signal to said voltage controlled oscillator according to the amplitude and/or phase of the driving signal of the transducer.Type: GrantFiled: October 10, 1974Date of Patent: June 29, 1976Assignee: Oki Electric Industry Company, Ltd.Inventors: Akinori Watanabe, Katsuhide Tanoshima, Takao Ando, Akira Tohama, Akio Nagano
