Abstract: A crosslinked rubber composition for a brake hose includes ethylene ?-olefin diene rubber and carbon black. The ethylene ?-olefin diene rubber contains ethylene propylene diene rubber (EPDM) and ethylene butene diene rubber (EBDM), and the mass ratio of EPDM/EBDM is 30/70 to 80/20. The carbon black contains only specific carbon black exhibiting an iodine adsorption amount of 15 to 33 mg/g and a DBP absorption amount of 50 to 155 cm3/100 g. The crosslinked rubber composition exhibits a T10 of ?50° C. or less as determined by a Gehman torsion test and a volume specific resistance of 1.5×105 ?·cm or more.

Abstract: The present invention provides a polypeptide consisting of any of the following amino acid sequences and useful for determining Alzheimer's disease: (1) the amino acid sequence shown in SEQ ID NO: 1; and (2) an amino acid sequence resulting from substitution, deletion, addition or insertion of one to several amino acids in the amino acid sequence shown in SEQ ID NO: 1.

Abstract: The invention is to permit a bushing main body of rubber elastomer to be adhered to a bar member while retaining a necessary contact pressure for adhering and after adhering, to permit a further compressive force to be imparted. The bushing main body (10) having a bore (11), through which the bar member (B) passes, and a bracket (20) holding the former are longitudinally split into two, respectively, the resulting split rubber bodies (10a)(10b) are vulcanization bonded to inner peripheral surfaces of the resulting half bracket members (20a)(20b). The inside diameter (D1) of both split rubber bodies as molded is made smaller than the outside diameter (D2) of the bar member, and inner peripheral surfaces (11a)(11b) at the bore are formed to be eccentric on mutually opposite sides.
