  • Publication number: 20230172527
    Abstract: There are provided a system, an apparatus, a program, and a method for enabling objective evaluation of a three-dimensional cognitive ability through quantification. A three-dimensional cognitive ability of a measurement target person is evaluated by acquiring a position of a moving object, the position enabling identification of a distance between the moving object and the measurement target person, by receiving input of an active response of the measurement target person taken in response to a three-dimensional position of the object recognized by the measurement target person, and by determining whether the position of the object that is acquired and the response that is input correctly match.

  • Publication number: 20230094773
    Abstract: The RI-labeled anti-MUC5AC humanized antibody of the present invention is a conjugate of a chelating agent chelated with a radionuclide and an antibody (the radionuclide is a metal nuclide that emits ? particle or positron, and the antibody is a humanized antibody specifically binding to MUC5AC), and is superior in specificity for MUC5AC and accumulation in tumor. Therefore, it is extremely useful for the treatment and/or diagnosis of diseases in which MUC5AC is overexpressed, particularly cancer.

  • Publication number: 20210338170
    Abstract: Provided is a method for assessing a correlation degree and an influence degree between a health degree in a health domain of concern and each preventive interventional action, based on biological information acquired in a time-series manner. The method comprises: acquiring biological information of an individual in a time-series manner; performing, based on the acquired biological information, an assessment of a health degree of the individual in a time-series manner; acquiring an intervention amount of each of one or more preventive interventional actions in a time-series manner; deriving a correlation degree and an influence degree between the time-series intervention amount of each of the one or more preventive interventional actions and the time-series health degree of the individual; and determining, as a relevant preventive interventional action, a preventive interventional action whose correlation degree is a given value or more, among the one or more preventive interventional actions.

  • Publication number: 20190145970
    Abstract: A problem to be solved by the present invention is to provide a method of inhibiting nonspecific reaction unique to feces in an immunochromatographic detection method in which a fecal sample is developed in an insoluble membrane to detect an analyte in the sample. It was found that nonspecific reaction caused by a fecal sample can be inhibited to accurately detect an analyte in the fecal sample by using a compound having in the molecule two or more carboxy groups. Particularly, it was found that nonspecific reaction unable to be inhibited by conventional methods can be inhibited for fecal samples of infants by using the sample diluent containing a compound having in the molecule two or more carboxy groups for the present invention, and the present invention was thereby completed.
