  • Patent number: 8437823
    Abstract: An easily wearable noninvasive living body measurement apparatus is provided. The noninvasive living body measurement apparatus (1) is composed of an apparatus body (3) and a wristband (40). The apparatus body (3) is composed of a body section (31) and a body section retention member (4). The body section (31) is retained by the wristband (40) via the body section retention member (4). By allowing the wristband (40) to be attached to a position in the vicinity of a wrist of a forearm of a human, the apparatus body (3) is attached to a human body. An imaging section (5) is retained at a position protruding outside from a width D of the wristband (40). This allows, when the wristband (40) is worn around the arm, the imaging section (5) to be located at a position at which the imaging by the imaging section (5) can be performed.

  • Patent number: 8160821
    Abstract: A method of supporting a diagnosis of an effect of a treatment by using anthracycline anticancer drugs is disclosed. The method provides a new value for judging an effect, a judgment score, which is calculated based on expression levels and activity values of two cyclin dependent kinases (CDKs). The effect of the treatment by using anthracycline anticancer drugs is judged by comparing the judgment score with a predetermined threshold level.

  • Publication number: 20050170353
    Abstract: To provide a gene examination method for predicting the onset risk of glaucoma based on the relation between a glaucoma-associated gene and the onset of glaucoma, the onset of glaucoma in future is predicted by using as an indication mutations in the gene region involving the code region and/or the upstream region of a glaucoma-associated gene. In the base sequence represented by SEQ ID NO:1, mutation(s) in at least one of the following positions are detected, i.e., the 194-, 199-, 324-, 1051-, 1084-, 1627-, 1685-, 1756-, 1853-, 2830-, 3371-, 4037- and 4364-positions.

  • Patent number: 6349227
    Abstract: A non-invasive living body measuring apparatus includes an image capturing section for capturing an image of the irradiated portion of the living body. When the image capturing section captures first and subsequent images of a portion of a living body at different times and the data processing section extracts characteristic patterns from the images, and sets an analysis region in the first image, the data processing section sets an analysis region in subsequent images based on a relative shift amount between the characteristic patterns of the first and subsequent image requisite for matching the characteristic patterns to each other.

  • Patent number: 6181319
    Abstract: A method of displaying a scattergram includes measuring a plurality of particles with a particle measuring apparatus and preparing distribution data representing a frequency distribution of the particles on a two-dimensional coordinate plane based on a pair of parameters obtained from each of the particles. Thereafter, a scattergram is displayed based on the distribution data on a color display device by allowing the coordinates of a particle to correspond to a pixel, each of the pixels being made of three fundamental color luminescent components. A luminance of each of the three fundamental color luminescent components corresponds to a frequency of the particles on the scattergram. As such, the frequencies of the particles are displayed in different colors.
