Abstract: There is provided a method for producing a carbon material, including a carbon generation step of causing carbon dioxide to react with a reducing agent to generate carbon, in which, as the reducing agent, an oxygen-deficient iron oxide represented by Fe3O4-? (where ? is 1 or more and less than 4), which is obtained by reducing magnetite while maintaining a crystal structure, or an oxygen-completely deficient iron (?=4) which is obtained by completely reducing magnetite is used.

Abstract: An object of the present invention is to provide a biomarker that enables selection of an embryo having a high rate of implantation and pregnancy, that is, an embryo having high fertility, from embryos obtained through embryo culture after in vitro fertilization in infertility treatment, and a criterion therefor. Provided is a criterion that enables identification of an ovum suitable for implantation and pregnancy based on measurement of the concentration of soluble CD163 which is present in follicular fluid collected at the same time as an ovum in ovum pick up in infertility treatment, or which is present in serum immediately before the ovum pick up.

Abstract: The present invention provides methods in the context of Kawasaki disease including measuring the level of at least one of lipopolysaccharide binding protein, leucine-rich alpha-2-glycoprotein, angiotensinogen and retinol binding protein 4 in a sample derived from a subject.

Abstract: A gel electrolyte secondary battery includes a positive electrode, a negative electrode containing a binder-containing negative electrode mixture and a gel non-aqueous electrolyte, wherein the binder contains polyvinylidene fluoride and polyacrylonitrile or a styrene-butadiene rubber.
