Publication number: 20220022851Abstract: The present invention provides a method for determining the likelihood of colorectal cancer development in a human ulcerative colitis patient, the method including: a measurement step of measuring methylation rates of one or more CpG sites present in specific differentially methylated regions in DNA recovered from a biological sample collected from the human ulcerative colitis patient; and a determination step of determining the likelihood of colorectal cancer development in the human ulcerative colitis patient based on average methylation rates of the differentially methylated regions which are calculated based on the methylation rates measured in the measurement step and a preset reference value or a preset multivariate discrimination expression, in which the reference value is a value for identifying a cancerous ulcerative colitis patient and a non-cancerous ulcerative colitis patient, which is set for the methylation rate of each differentially methylated region, and the multivariate discrimination expresType: ApplicationFiled: October 13, 2021Publication date: January 27, 2022Applicants: Hanumat Co., Ltd., EA Pharma Co., Ltd.Inventors: Masato KUSUNOKI, Yuji TOIYAMA, Koji TANAKA, Toshimitsu ARAKI, Akira MITSUI, Kenji TAKEHANA, Tsutomu UMEZAWA

Patent number: 11140318Abstract: The present invention is provided with an imaging unit (10) that has an imaging head (11) to be inserted into the digestive tract (112) and images a living body by applying a laser to the digestive tract (112) via the imaging head (11); a control unit (50) for controlling the imaging head (11) to move inside the digestive tract (112); and an image processing unit (70) for processing an image captured by the imaging unit (10). The imaging unit (10) captures a plurality of imaging regions (P) to be imaged along with the movement of the imaging head (11) such that a portion of adjacent imaging regions (P1, P2) overlap, and the image processing unit (70) overlaps regions (Pa) in which the plurality of imaging regions (P1, P2) are overlapped to generate a composite image.Type: GrantFiled: February 23, 2017Date of Patent: October 5, 2021Assignee: Mie UniversityInventors: Akira Mizoguchi, Koji Tanaka, Yuji Toiyama, Kyosuke Tanaka, Shujie Wang, Aika Kaito, Kousyoku Sai, Kazushi Kimura
