  • Patent number: 11371982
    Abstract: The purpose of the present invention is to provide a method for accurately predicting a cancer patient prognosis based on a count of desired cells for which expression of a leukocyte marker and an epithelial marker is hardly exhibited by detecting those cells. Provided is a method for diagnosing an overall survival prognosis for a patient suffering from cancer, the method including: a step of obtaining a concentrated solution containing desired cells by pre-treating a biological sample obtained from the patient; a step of optically detecting the concentrated cells; and a step of detecting the desired cells from the detected image, wherein an association is made with the overall survival prognosis diagnosis by counting the detected desired cells, and wherein the desired cells are cells confirmed by the existence of a cell nucleus and in which expression of a leukocyte marker and an epithelial marker is hardly exhibited.

  • Publication number: 20050239067
    Abstract: The present invention simply, rapidly and accurately detects, quantitatively determines and types genes of protein groups [which refer to TDH (Thermostable direct hemolysin), TRH (TDH-related hemolysin) and other analogous hemolysin proteins, hereinafter referred to as TDH-related toxins] of thermostable hemolysin groups produced by pathogenic bacteria of the genus Vibrio. Present Invention provides a method which enables detection and quantitative determination of actual TDH-related toxin-producing bacteria, which are important in food hygiene control. Using a primer pair which contains gene sequences encoding common amino acid sequences of TDH and TRH, TDH-related toxin genes are comprehensively detected and determined, thereby TDH-related toxin-producing bacteria themselves are detected and quantitative determined.
