Patent number: 10828378Abstract: The present invention provides a nucleic acid construct for expressing an oxidative stress indicator comprising: a nucleic acid sequence encoding an Nrf2 protein-derived partial protein that comprises at least an Neh2 domain sequence and substantially lacks or is functionally deficient in an Neh1 domain sequence or an Neh1-Neh3 domain sequence; a stress-inducible promoter sequence positioned upstream of the nucleic acid sequence encoding an Nrf2 protein-derived partial protein; and a nucleic acid sequence encoding a protein capable of generating a detectable signal, the nucleic acid sequence being positioned downstream of the nucleic acid sequence encoding an Nrf2 protein-derived partial protein. The present invention also provides a method for measuring oxidative stress and a method for screening for an anti-oxidative stress agent, using the nucleic acid construct.Type: GrantFiled: January 20, 2012Date of Patent: November 10, 2020Assignee: RikenInventors: Takao Iwawaki, Daisuke Oikawa

Patent number: 9314726Abstract: In a case structure for a fluid pressure device, a filter that constitutes part of a fluid pressure unit is equipped with a first body, a case unit connected to a lower portion of the first body, and a filter unit accommodated in the interior of the case unit. The case unit is made up from an outer case, which is formed as a bottomed cylinder from a light-permeable transparent material, and an inner case inserted into the interior of the outer case. Additionally, by insertion of the case unit into an installation hole that opens on a lower portion of the first body and rotating the case unit, projections and retaining walls provided on an outer circumferential surface of the case unit engage with support members provided in the installation hole, thus placing the case unit in a connected state.Type: GrantFiled: July 21, 2011Date of Patent: April 19, 2016Assignee: SMC KABUSHIKI KAISHAInventors: Norihide Yamase, Daisuke Oikawa
