  • Publication number: 20210271062
    Abstract: An observation device includes a microscope. The microscope includes an illumination light beam source, an illumination optical system, and an observation optical system forming an optical image of an observation target from reflected light beams obtained by reflection of illumination light beams by the observation target. The observation optical system includes a phase plate changing the phase of directly reflected light beams reflected on a reflection surface among the reflected light beams. Both the illumination optical system and the observation optical system are arranged under the observation target. The observation device includes an image pickup device photoelectrically converting the optical image obtained by the observation optical system to create image data of the observation target and a display device displaying the image data. The illumination light beam emitted from the illumination optical system is a collimated light beam.

  • Publication number: 20190227067
    Abstract: [Problem] The present invention addresses the problem of providing a novel biomarker which makes it possible to find the prognosis of glioma, the risk of distant recurrence of glioma, the invasion ability of glioma cells and the like and also makes it possible to detect the prognosis, the risk, the invasion ability or the like in an earlier stage of a therapy of glioma. [Solution] The present invention relates to a method for evaluating the prognosis of glioma, said method comprising the steps of: detecting ACTC1 protein and/or mRNA encoding the protein in a glioma-containing sample collected from a patient; and determining that the prognosis of the glioma is poor when the ACTC1 protein and/or the mRNA encoding the protein is detected in the aforementioned step. According to the present invention, the prognosis of glioma, the risk of distant recurrence of glioma, the invasion ability and the like can be evaluated using a novel biomarker, i.e., ACTC1 protein and/or mRNA encoding the protein.
