Provided is a vital stain inspection method for distinguishing between cancer cells and normal cells within a lumen, or on the serous membrane side of an organ, by means of laser irradiation after organ tissue has been stained by curcumin, Red #3 or Red #106, which are edible color dyes.

Detection method

A cancer test device () is provided with: an application unit () for applying a staining agent (), which can selectively stain a product of a cancer-relating gene in a living cell a chromatic color, onto a group of living cells; an imaging unit () for imaging the group of living cells having the staining agent () applied thereto; and a determination unit () for determining the level of malignancy of cancerization of the group of living cells on the basis of the state of the stained expression pattern of the cancer-relating gene in the group of living cells in an image obtained by the aforementioned imaging.

Cancer test device, cancer test method, and staining agent for use in cancer test

A vital stain for observation under multiphoton laser microscopy, the vital stain comprising one or more edible dye compounds.

Vital stain

The present invention is provided with an imaging unit () that has an imaging head () to be inserted into the digestive tract () and images a living body by applying a laser to the digestive tract () via the imaging head (); a control unit () for controlling the imaging head () to move inside the digestive tract (); and an image processing unit () for processing an image captured by the imaging unit (). The imaging unit () captures a plurality of imaging regions (P) to be imaged along with the movement of the imaging head () such that a portion of adjacent imaging regions (P, P) overlap, and the image processing unit () overlaps regions (Pa) in which the plurality of imaging regions (P, P) are overlapped to generate a composite image.

Laser endoscope device

The present invention aims to provide a sheet of microfiber assembly having a high filtering performance suitable as an oil-mist filter. A sheet of microfiber assemblycomprises microfiberseach having a fiber diameter of 3,000 nm or less and is formed of a mixture of water-insoluble but alcohol-soluble acetalized polyvinyl alcohol resin and water-insoluble but alcohol-soluble fluorine resin.

A highly antimicrobial composition having characteristics of a lactic acid polymer such as biodegradability is prepared by combining a lactic acid oligomer with a metal salt thereof.

Antimicrobial composition, process for preparing the same, and utilization thereof

A system for decomposing a liquid or gaseous organic compound comprises a ultraviolet decomposition unit and an intermediate product treatment apparatus. The ultraviolet decomposition unit decomposes an organic compound contained in polluted liquid or polluted gas by irradiating ultraviolet rays whose wavelength is less than 300 nm to the polluted liquid or the polluted gas containing the organic compound. An acid electrolytic water feed pipe and an alkali electrolytic water feed pipe are respectively connected to the intermediate product treatment apparatus through valves to neutralize an intermediate product, which results from decomposition of the organic compound, for decomposition by selectively adding strong alkali electrolytic water and strong acid electrolytic water to the polluted liquid or the polluted gas containing the intermediate product.

System for decomposing organic compound

An electrostatic filter includes a fibrous component including a mixture of wool and synthetic fibers and a resinous component including a perfluoroalkyl acrylate copolymer resin and a p-tert-butylphenol formaldehyde resin, which resinous component is adhering to the fibrous component, both of the fibrous substrate component and the resinous component being in electrostatically charged conditions.
