Abstract:
PROBLEM TO BE SOLVED: To properly specify an area of a desired cell constituent element and to display the presence or absence of expression of a desired target molecule on this cell constituent element with a good visibility. SOLUTION: In the microscope system 1, a high resolution image acquisition processing unit 453 acquires a VS image of a target specimen S stained with a staining dye containing a dye for cell component identification and a molecule target dye. A dye amount calculation unit 457 calculates, for each pixel of the VS image, a dye amount of each staining dye that stains corresponding positions on the specimen. A cell component identification processing unit 458 identifies a cell component based on the dye amount of the dye for cell component identification. An extraction condition setting unit 459 sets the presence or absence of a target molecule in the area of the cell component as an extraction condition. A target portion extraction unit 460 extracts an area of a target portion in the target specimen S that satisfies the extraction condition. A display image generator 462 generates a display image of the VS image representing the area of the target portion. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a platelet aggregation inhibitor taking Aggrus as a target and having 3-phenoxychromone compound as an active ingredient, and a pharmaceutical composition containing such platelet aggregation inhibitor, used for inhibiting platelet aggregation and for the prevention and/or treatment of cancerous tumor.SOLUTION: By screening low molecular weight compounds inhibiting the Aggrus-dependent platelet aggregation and also bonding with the Aggrus and inhibiting the interaction with CLEC-2, the 3-phenoxychromone compounds, especially a 3-phenoxychromone compound having carboxyalkyleneoxy group at the 7 position is found to have an excellent behavior. Also provided are the platelet aggregation inhibitor containing the compound as the active ingredient and the pharmaceutical composition containing such platelet aggregation inhibitor, used for inhibiting the platelet aggregation and for the prevention and/or treatment of the cancerous tumor.
Abstract:
PROBLEM TO BE SOLVED: To provide a new anticancer agent and a new method of screening an anticancer agent.SOLUTION: This method of screening the anticancer agent includes: a process of bringing a cancer cell manifesting TACC3 protein and a candidate substance into contact with each other; a process of measuring the percentage of a mitotic cell for the cell brought into contact with the substance; and a process of measuring the manifestation or function of the TACC3 protein in the cell brought into contact with the substance. An anticancer agent to at least one selected from a group including lymphoma, angiosarcoma, non-small cell lung cancer, breast cancer, digestive tract tumor and ovarian cancer contains shRNA or siRNA to the TACC3 taking at least one array selected from a group including specific arrays as a target.

PROBLEM TO BE SOLVED: To provide an image processing apparatus, an image processing method and programs for accurately detecting any notable cellular tissue area on pathological images.SOLUTION: The image processing method includes the step S11 to compute luminance difference characteristic of each pixel in a low resolution pathological image, and categorize low resolution pathological images into cellular tissue area and anything else based on the computed luminance difference characteristic; the step S12 to expand the cellular tissue area; the step S13 to separately-label each cellular tissue area (with expansion process completed); the step S14 to compute star part level score SA of each cellular tissue area and then determine each area as a star or a non-star; and the step S15 to establish rectangular area (rectangle cellular tissue area) to be inscribed with the cellular tissue area determined as a star. This invention is applicable to analysis of pathological images.
