Abstract: A GLP-1 secretion promotion agent that includes a GPR84 agonist as an active ingredient.

Abstract: To provide a method and kit for measurement of a target substance with high detection sensitivity, provided is a method of measuring at least any one of the presence or absence, and a concentration, of a target substance in a sample liquid, the method including the steps of: (a) preparing a first particle that specifically binds to the target substance and contains a rare earth complex, and a second particle that has a larger average particle diameter than that of the first particle and specifically binds to the target substance; (b) mixing the sample liquid, the first particle, and the second particle to provide a mixed liquid; and (c) determining at least any one of the presence or absence, and the concentration, of the target substance from polarization anisotropy of the mixed liquid obtained in the step (b).

Abstract: Provided is a particle having high detection sensitivity in the detection of a substance to be measured, such as an antigen or an antibody, from a body. The particle includes a rare earth complex, wherein the particle has a particle size distribution of 0.1 or less in terms of polydispersity index (pdi) measured by dynamic light scattering, and wherein the particle has a hydrophilic polymer on a surface thereof.

Abstract: An oil-based release agent of the present invention contains a petroleum-based hydrocarbon solvent (a) and a high temperature adhesive (b), is applied to a metal die used for die casting or casting, has high adhesion and high lubricity even with respect to a metal die at a high temperature particularly of 300° C. or higher, and can prevent seizure. In addition, the present invention provides a method for applying the oil-based release agent of the present invention by controlling an adhesion amount thereof by micronization and speed-control thereof with respect to a metal die at a high temperature, and an electrostatic application method.

Abstract: A method for rust-proofing a mold, which is capable of reducing the time and the cost required for rust-proofing the mold. The method includes an iron hydroxide-forming step for forming iron hydroxide on a predetermined part of the surface of the mold, and a surface-treating step for forming a film covering the molding surface of the mold, and for changing the iron hydroxide formed on the mold into black rust, by heating the mold, under an oxygen-deficiency atmosphere, on which the iron hydroxide is formed in the iron hydroxide-forming step.

Abstract: A mold releasability evaluating apparatus includes a forming die that includes a bottom portion having a main surface, and a wall surface portion that is connected to the main surface of the bottom portion and has a wall surface in which an angle formed with the main surface of the bottom portion is an obtuse angle; an extrusion pin capable of protruding out from the main surface of the bottom portion in a direction that separates a compact from the main surface of the bottom; and a measuring device configured to measure a load applied to the extrusion pin when the extrusion pin pushes the compact away from the main surface of the bottom portion, after one surface of the compact is formed by the main surface of the bottom portion.
