  • Publication number: 20240209108
    Abstract: An object of the present invention is to provide an anti-CLDN4/anti-CD137 bispecific antibody usable in treatment of cancer. An anti-CLDN4/anti-CD137 bispecific antibody produced using an anti-CLDN4 antibody binding to CLDN4 and an anti-CD137 antibody binding to CD137 had agonistic activity for CD137, promoted production of interferon ? by a T cell, and exhibited cytotoxic activity against a cancer cell expressing CLDN4 on a cell surface thereof. Besides, it was shown that the anti-CLDN4/anti-CD137 bispecific antibody can be safely administered to monkeys. Therefore, the anti-CLDN4/anti-CD137 bispecific antibody is usable in treatment of human cancer.

  • Publication number: 20240173773
    Abstract: A build apparatus builds a first structural layer by irradiating a first beam position, builds a first build object and irradiating the first build object, a second irradiation beam position builds a second build object. The build apparatus further builds a second structural layer by irradiating the first structural layer, a third irradiation beam position builds a third build object and by irradiating the third build object, a fourth irradiation beam position builds a fourth build object. At least one of a distance between first and second position and a distance between third and fourth position is shorter than a distance between second and third position. Thus, the build apparatus builds a structural object including the first and second structural objects and is inclined with respect to an optical axis direction.

  • Publication number: 20240166736
    Abstract: An objective of the present invention is to provide an anti-TSPAN8/anti-CD3 bispecific antibody and an anti-TSPAN8 antibody usable in treatment or prevention in human. A human monoclonal antibody producing mouse was immunized with a peritoneal disseminated cancer cell isolated from a patient, to obtain an antibody 16B11 and an antibody 16B12 that selectively bind to a peritoneal disseminated cancer cell. These antibodies were anti-TSPAN8 antibodies that bind to the region from amino acid positions 126 to 155 of TSPAN8 and exhibited strong binding activity to TSPAN8 expressed in the peritoneal disseminated cancer cell. Further, an anti-TSPAN8(16B11)-anti-CD3 bispecific antibody produced based on the sequence of 16B11 exhibited a cytotoxic activity against the TSPAN8-expressing cancer cell in vitro, exerted an anti-tumor action on TSPAN8-expressing cancer cell-bearing mice in vivo, and extended the lifetime of peritoneal dissemination model mice.

  • Patent number: 11736830
    Abstract: A solid-state imaging element includes a pixel and an image processing unit. The pixel has a common transistor, a charge accumulation unit, and a power supply. The common transistor has a first terminal and a second terminal. The common transistor maintains a voltage of the first terminal at a predetermined voltage with a voltage applied from the power supply and outputs a voltage corresponding to a change in a voltage of the charge accumulation unit from the second terminal, based on a condition that an element voltage is a ground voltage. The common transistor outputs a voltage corresponding to a change in a voltage of the charge accumulation unit from the first terminal, based on the element voltage is higher than the ground voltage. The image processing unit generates a luminance image according to a change in the voltage output from the second terminal of the common transistor.

  • Publication number: 20230195019
    Abstract: An image forming apparatus includes a stacking portion including a lifting portion, a feeding member feeding a sheet stacked on the lifting portion to a conveyance passage, a position detector detecting movement of the sheet stacked on to a feedable position to the conveyance passage, a driver including a motor and performing the lifting operation of the lifting portion, a rotation detector detecting rotation of the motor, and a controller. The controller determines a factor that the position detector does not detect the movement of the sheet stacked on the lifting portion to the feedable position within a predetermined time based on a detection result of the rotation detector while controlling the driver to lift up the lifting portion.
