  • Publication number: 20220022851
    Abstract: 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 expres

  • Publication number: 20210393159
    Abstract: A medical support system includes a first transmitting antenna attached to a body surface that transmits a first transmitting wave, and a reflector that is present in the body and reflects the first transmitting wave transmitted from the first transmitting antenna. A first receiving antenna attached to the body surface receives the first transmitting wave transmitted from the first transmitting antenna and a reflected wave reflected by the reflector, and a location estimation device estimates the passage of the reflector in the body based on changes in the respective phases of the first transmitting wave received by the first receiving antenna and the reflected wave, at time t and time t+?t.
