Abstract: A method for differentiating a human differentiated cell-derived pluripotent stem cell into a neural stem cell is provided, which includes the steps of: making an embryoid body from the human differentiated cell-derived pluripotent stem cell; and culturing the embryoid body in a medium containing LIF to differentiate into a neural stem cell, so that, when the neural stem cell is allowed to differentiate in vitro after multiple subculturing of the neural stem cell, it differentiate mainly into neurons but substantially not into glial cells.
Abstract: A genetic marker is provided that can determine whether or not a cancer tissue contains a heterogeneous cancer cell population, the genetic marker being selected from the group consisting of CALML3, BGN, CLCA2, CSTA, ALDH1A1, NGFR, S100A8, ELN, SNURF, and LGALS7.
Abstract: Provided is a technique for using an optical microscope image of an area on a sample to collect area-specific information characterizing each kind of biological tissue from imaging mass analysis data. On an optical image of a two-dimensional target area on a sample, a difference is examined in the kind of tissue or other features and areas are specified, each regarded as the same kind of tissue. When data processing is initiated, peak information is extracted, for each specified area, from mass spectrum data of all the measurement points. A peak method is applied to each area to extract peak information. Then, when a command to compare a set of areas is given, the peak information of those areas is collected. By comparing the peak information of different areas by a machine learning algorithm or similar judging technique, area-specific peak information is obtained, and this information is stored in memory.

Abstract: An object of the present invention is to provide, as a simple method, a surface nitriding treatment method of a titanium material, forming a hardened nitrided layer excellent in abrasion resistance on the surface of a titanium material in a shorter time. In order to achieve the object, the present invention adopts a surface nitriding treatment method of a titanium material, wherein a hardened nitrided layer is formed on the surface of the titanium material, by blowing nitrogen gas at a flow rate of 10 L/min or more to the surface of the titanium material while the titanium material is being heated to 800° C. to 1000° C. in an inert gas atmosphere.
Abstract: An image acquisition unit (2020) acquires an analysis image. The analysis image is an image in which a plurality of cell nuclei in a lesion of a target person are captured. A feature-value calculation unit (2040) calculates the feature-value relating to the cell nuclei from the analysis image. An evaluation function acquisition unit (2060) acquires an evaluation function from an evaluation function storage unit (10). The evaluation function is a function with which prediction information is calculated based on the feature-value. The prediction information generation unit (2080) generates prediction information relating to a target person based on a feature-value, which has been calculated from an analysis image, and an evaluation function which has been acquired by the evaluation function acquisition unit (2060). The prediction information is information indicating a prediction of a prognosis of a disease of the target person or a prediction of malignancy of a disease of the target person.

Abstract: A golf swing analysis device includes a joint force calculation section and a torque extraction section. The joint force calculation section generates a double pendulum model that includes a first link that corresponds to an upper part of a body of a golfer, a second link that corresponds to a golf club, and a joint that links the first link and the second link, and calculates a joint force applied to the joint along with a swing motion using an acceleration measured by an inertial sensor attached to the golf club. The torque extraction section extracts a torque that causes the second link to make a rotational motion around a first axis from the joint force.
