  • Patent number: 10702354
    Abstract: An object of the present invention is to provide an emission marker for being indwelled in a lumen, the emission marker having: a base part; a coil wound around the base part; an emission part electrically connected to the coil; and a cover part for covering at least the base part and the coil, wherein the emission part has a light source that emits visible light. Additionally, the present invention relates to a detector for detecting, from outside of a lumen, an emission marker indwelled in the lumen, the detector having a detection unit having an antenna that acts with a coil of the emission marker.

  • Patent number: 8841125
    Abstract: Disclosed is a novel cell mass derived from a cancer tissue, which can reflect the in vivo behavior of a cancer cell correctly. Also disclosed is a process for preparing the cell mass. Specifically disclosed is a cell mass derived from a cancer tissue, which is an separated product that is isolated from a cancer tissue obtained from an individual as a mass containing at least three cancer cells or a cultured product of the separated product and which can retain a proliferation ability in vitro. The cell mass derived from a cancer tissue is produced by, for example, a preparation process comprising the steps of: treating a pulverized product of a cancer tissue removed from a living body with an enzyme; and selecting and collecting a mass containing at least three cancer cells among from an enzymatic treatment product.
