Abstract: The invention features a transgenic mammal encoding a chimeric ornithine decarboxylase gene, which transgenic mammal exhibits phenotypic abnormalities. The invention also includes a chimeric transgene comprising ornithine decarboxylase.

Abstract: A printed sheet product comprises a thin core having a pair of opposing major planar sides. A plurality of sets of variable data fields are printed on at least a first side of the core. One or more of the variable data fields of each set may be printed on the opposing second side of the core. Each set of printed variable data fields includes at least a first data field printed with a numeric code, the numeric code of each variable data field set being different from that of each other set printed on the first side of the core. Each set of variable data fields further includes a second data field printed with either a name and mailing address uniquely associated with a numeric code or with another representation of the numeric code. Where printed, the name and address of each variable data set differs from that of each other variable data set printed on the first side of the core.

Abstract: The present invention provides a sealed battery having a large capacity by using a thin safety valve device so as to increase a volume of a cell element. The sealed battery has a high safety owing to the thin safety valve device having an elastic valve element comprising an ethylene-propylene elastomer and thermoplastic resin particles dispersed in the ethylene-propylene elastomer. The elastic valve element is produced by mixing thermoplastic resin particles with an ethylene-propylene elastomer material, molding the mixture into a predetermined shape and, at the same time, crosslinking the ethylene-propylene elastomer material.
