  • Publication number: 20210116445
    Abstract: An object of the present invention is to provide a method for detecting the presence or absence of a disease, the risk of developing a disease, the degree of progression of a disease and/or the degree of progression of aging, in a subject. The present invention achieves the above described object by a method including the following steps (a) to (c): (a) adding a solution containing an antibody obtained from a subject to a column filled with an insoluble carrier on which an Fc-binding protein is immobilized, to allow the antibody to be adsorbed on the carrier; (b) eluting the antibody adsorbed on the carrier using an eluent, to obtain data of a separation pattern of the antibody; and (c) detecting the presence or absence of a disease, the risk of developing a disease, the degree of progression of a disease and/or the degree of progression of aging, in the subject, using the data as an indicator.

  • Patent number: 9084985
    Abstract: Provided is a method for producing an alicyclic carboxylic acid by hydrogenating an aromatic ring of an aromatic carboxylic acid, which comprises using a catalyst containing ruthenium and palladium as a catalyst, and also provided is a co-supported ruthenium-palladium catalyst in which ruthenium and palladium are present in a form of particles containing both the ruthenium and palladium on a surface of a support. A catalyst has been developed which uses a relatively inexpensive noble metal, ruthenium, which has an activity equivalent to that of a rhodium catalyst, and which does not undergo decrease in activity as observed in a rhodium catalyst, and thereby an industrially simple method for producing an alicyclic carboxylic acid has been established.

  • Patent number: 8163189
    Abstract: Nanoporous substrate with fine pores having a diameter from 3 to 40 nm arranged with less than 60 nm periodicity is prepared by a method comprising the steps of coating amphipathic block copolymer on a substrate, forming a film containing hydrophilic cylinders aligned perpendicularly to the surface of the film on a substrate, and immersing the substrate into a solution containing an etchant.
