  • Publication number: 20080096981
    Abstract: A novel TH2 associated gene that is induced by IL-9 has been identified and isolated, thereby providing a therapeutic target for IL-9 mediated diseases such as atopic allergy and asthma-related disorders. The invention also includes methods for the identification and use of small molecule inhibitors of this gene and its products to treat these disorders, methods for diagnosing susceptibility to, and assessing treatment of atopic allergy or asthma-related disorders by measuring the level of gene expression in biologic samples using antibody specific for this protein. The use of this protein as a therapeutic agent for the treatment of autoimmune diseases is also indicated.

  • Patent number: 4305105
    Abstract: A linear actuator for a magnetic disc drive has shortened magnetic flux lines totally confined within the actuator housing whereby the actuator can be placed in closer proximity to a disc and thus reduce the size of the disc drive package. The actuator includes a generally cylindrical housing with magnets attached to the inside surface of the housing. A cylindrical bobbin having a voice coil wound on its periphery is positioned within the housing and linearly movable therein with the voice coil in close proximity to the magnets. An annular magnetic flux transmission means is attached to one face of the housing and a flux transmission plate is attached to the opposite face of the housing with the flux transmission means providing magnetic flux paths and preventing flux leakage from the housing.
