Abstract: The invention provides a gold-supporting catalyst comprising gold nanoparticles and a carrier consisting of porous ceramic obtained by firing a mixture comprising an aluminum compound, a lime component, and a plastic clay containing 1% by mass or less of feldspars and quartz, wherein the gold nanoparticles are supported in an amount of 0.01 to 10 parts by mass on the carrier based on 100 parts by mass of the carrier.

Abstract: A resin composition having excellent dispersibility, discoloration resistance and antimicrobial properties by blending a resin (A) with an antimicrobial agent (B) in which at least one kind of metal ion selected from the group consisting of silver, copper, zinc and tin is supported on zeolite, and an antimicrobial agent (C) that includes a silver ion-containing phosphate as an active ingredient, or an antimicrobial agent (D) made of a soluble glass powder containing silver ion.

Abstract: Artificial hair having a look and feel that both are close in character to that of natural human hair, compared with artificial hair made from polyamide fibers, polyester fibers, acrylic fibers, etc., and which holds that character over time. By means of artificial hair composed of monofilaments containing poly(trimethylene terephthalate), in particular, by means of artificial hair composed of monofilaments containing poly(trimethylene terephthalate) having a denier of 22 to 333 dtex, a melting point of 225 to 235° C., a glass transition temperature of 45 to 80° C., the physical properties of elastic recovery, strength, stretch, and texture resemble natural human hair, and the occurrence of frizzes and gloss is kept under control.

Abstract: The present invention provides a resin composition having excellent dispersibility, discoloration resistance and antimicrobial properties by blending a resin (A) with an antimicrobial agent (B) in which at least one kind of metal ion selected from the group consisting of silver, copper, zinc, and tin is supported on zeolite, and an antimicrobial agent (C) that includes a silver ion-containing phosphate as an active ingredient, or an antimicrobial agent (D) made of a soluble glass powder containing silver ion.

Abstract: Compounds represented by the following general formula and salts thereof; Y-L-Tyr-Q-NR1—CH(R2)—CO—X, wherein R1 represents hydrogen or C1-6 alkyl; R2 represents optionally substituted benzyl; Q represents D- or L-Arg; Y represents two hydrogen atoms of N-terminal amino group of L-Tyr, or one or two functional groups substituting for the hydrogen atoms, for example, a C1-6 alkyl optionally having amino or carboxy; and X represents N-methyl-&bgr;-alanine and other. The compounds have analgesic effect and can be used for the treatment of cancer pain or the like.

Abstract: Novel compound of the following formula ##STR1## wherein X is a member selected from the group consisting of carboxy and carbalkoxy and each or R.sub.1, R.sub.2 and R.sub.3 is a member selected from the group consisting of hydrogen, alkyl, alkenyl, aryl, alkoxy, hydroxy, halo, amino, alkylamino, alkylmercapto, nitro, cyano, alkylsulfonyl, carboxy, carbalkoxy, hydroxyalkyl, aminoalkyl, hydroxyalkylamino, and acetoxyalkylamino, and pharmaceutically acceptable acid addition salts thereof.The above compound can be prepared by heating a 3-(substituted amino)-acridine to cyclize said compound, and if desired, hydrolyzing the resulting product and/or it with an acid.
