  • Patent number: 11332527
    Abstract: A subject of the present invention is to provide an anti AQP3 antibody specifically recognizing the extracellular domain of aquaporin 3 (AQP3), which is one type of a water channel protein. By selecting a monoclonal antibody which specifically binds to an oligopeptide included in loop C as one of the extracellular domains of AQP3, an anti AQP3 antibody that is desired in the present invention is provided. An anti AQP3 monoclonal antibody of the present invention can directly bind, from the outside of a cell, to AQP3 present in a cell membrane. Furthermore, as an anti AQP3 monoclonal antibody of the present invention can have an inhibitory activity, the function of permeating a low molecular weight molecule or the like, which is carried by AQP3, can be suppressed.

  • Publication number: 20220134542
    Abstract: A position/force controller performs a first conversion for distributing control energy to at least one of velocity or position energy and force energy, in accordance with a function to be realized, based on velocity (or position) and force information, which correspond to information relating to a position based on an operation of an actuator, and information serving as reference of control. The position/force controller calculates at least one of a velocity or position control amount and a force control amount based on at least one of the energies obtained through the distribution. The position/force controller integrates the calculated control amounts, performs a second conversion, and determines input to the actuator. The position/force controller performs a process, corresponding to increasing or decreasing performed on at least one of the velocity or position energy and the force energy together or independently, with satisfaction of a condition set for the control energy.
