  • Patent number: 11760807
    Abstract: A method is provided for determining the efficacy of GPC3-targeting drug therapy for cancer in a patient before the start of GPC3-targeting drug therapy or for determining the continuation of GPC3-targeting drug therapy for a patient treated with GPC3-targeting therapy. The method includes determining the number of an immunocyte or an expression level of a molecule expressed on the immunocyte in a biological sample isolated from the patient before the start of GPC3-targeting drug therapy and/or the patient treated with the GPC3-targeting drug therapy, wherein when the number of the immunocyte or the expression level of the molecule expressed on the immunocyte is a predetermined value, the efficacy of the GPC3-targeting drug therapy is determined or the continuation of the GPC3-targeting drug therapy is determined. GPC3-targeting drugs and drug preparations for use according to the disclosed methods are also provided.

  • Patent number: 11376326
    Abstract: The present invention provides a method for determining the efficacy of a GPC3-targeting therapeutic agent for a liver cancer patient and a GPC3-targeting therapeutic agent or a preparation which is to be administered to a patient for whom it has been determined that the GPC3-targeting therapeutic agent is effective. The present invention provides, for example, a method for determining that a GPC3-targeting therapeutic agent is effective when the expression level of GPC3 per tumor cell is a predetermined value, and a GPC3-targeting therapeutic agent or a preparation which is to be administered to a patient for whom it has been determined that the GPC3-targeting therapeutic agent is effective.

  • Patent number: 4158380
    Abstract: A continuously casting machine is provided with structure for agitating under action of magnetic force the molten steel in a slab drawn from a mold. The agitating device comprises permanent magnet groups arranged on both surfaces of the longitudinal sides of the slab and extending from the part directly below the mold to the completely solidified part of the slab. Direct current is passed to the molten steel in the slab, thereby providing the agitating force under the mutual action of a stationary magnetic field and direct current to the molten steel.

  • Patent number: 3962794
    Abstract: In a continuous casting machine, displacement-electricity converters are mounted slidably longitudinally on a long guide having the same radius of curvature as that of the roller apron of the casting machine. The long guide is inserted between the rolls of the roller apron. The displacement of the roller apron with respect to each reference position is measured with the displacement-electricity converters.
