Patent number: 8729464Abstract: This invention provides a method or device for determining the stage of chronic kidney disease. The present invention relates to a method for determining a stage of chronic kidney disease in a subject suffering from kidney disease, the method comprising the steps of: (A-1) measuring the content of at least one marker selected from the group consisting of markers (1) to (16) in a specimen from the subject, (B-1) determining the stage indicated by each marker by comparing the content of the at least one marker in the specimen from the subject, which has been measured in step (A-1), with a reference content range determined in each stage, and (C-1) determining that when each marker indicates the same stage, which has been determined in step (A-1), the chronic kidney disease in the subject is in that stage.Type: GrantFiled: May 30, 2011Date of Patent: May 20, 2014Inventors: Noriaki Tanaka, Masahiro Kohno, Emiko Sato, Kouichi Fujiwara

Patent number: 8501385Abstract: A positive-tone radiation-sensitive composition is used in a resist pattern-forming method as a first positive-tone radiation-sensitive composition. A positive-tone radiation-sensitive composition includes a polymer, a photoacid generator, and a solvent. The polymer includes an acid-labile group and a crosslinkable group. The resist pattern-forming method includes providing the first positive-tone radiation-sensitive composition on a substrate to form a first resist pattern on the substrate. The first resist pattern is made to be inactive to light or heat so that the first resist pattern is insoluble in a second positive-tone radiation-sensitive composition. The second positive-tone radiation-sensitive composition is provided on the substrate to form a second resist pattern on the substrate on which the first resist pattern is formed.Type: GrantFiled: January 13, 2011Date of Patent: August 6, 2013Assignee: JSR CorporationInventors: Yusuke Anno, Kouichi Fujiwara, Makoto Sugiura, Gouji Wakamatsu
