  • Publication number: 20130012408
    Abstract: A method of determining the presence or the absence of a glaucoma risk by detecting in vitro an allele and/or a genotype of a single nucleotide polymorphism, comparing the allele and/or the genotype detected with at least one of an allele and/or a genotype with a high-risk allele, wherein the presence of a glaucoma risk is determined in a case where the allele detected is the high-risk allele, or the presence of a glaucoma risk is determined in a case where the genotype detected is a homozygote of the genotype comprising the high-risk allele or a heterozygote when the high-risk allele complies with a dominant genetic model, or the presence of a glaucoma risk is determined in a case where the genotype detected is a homozygote of the genotype comprising the high-risk allele when the high-risk allele complies with a recessive genetic model.

  • Publication number: 20040086511
    Abstract: Neuronal cell death, as modeled by removal of serum or NGF from growth medium, is characterized by many changes in gene expression. Gene expression was compared before and after withdrawal of serum or NGF. These results provide clues to underlying molecular processes occurring during neuronal and photoreceptor degeneration, and provide direction for future cell-based studies.

  • Patent number: 6597344
    Abstract: A key switch in which a pair of lever members which form a cross-link member are molded out of resin materials having different shrinkage coefficients. A shaft-receiving hole is formed in the lever member molded out of the resin material having a small shrinkage coefficient, while a linking shaft is formed on the lever member molded out of the resin material having a large shrinkage coefficient. When the key switch is structured in this way, after the lever member having the shaft-receiving hole has been molded, the resin material having a large shrinkage coefficient is hardened in a die in which the shaft-receiving hole forms a portion of a cavity in order to form the other lever member. By forming the other lever member, the linking shaft is formed in a pivotally mounted state in the shaft-receiving hole. Therefore, it is no longer necessary to link the pair of lever members by a manual operation.

  • Patent number: 6483050
    Abstract: A key switch includes an actuator for rotatably engaging the upper end of one of lever members, which constitute a cross-linked member, therewith and slidably engaging the upper end of the other lever member therewith. After the cross-linked member engaged with the actuator at its upper end is mounted on a membrane switch, the bottom of a key top is retained on the actuator by a simple means a as press fitting. This simplifies a molding die for the key top and facilitates an operation of attaching the key top.
