  • Patent number: 12213860
    Abstract: Provided are a method for separating mammalian sperm, by which even a large amount of sperm can be separated in a short time and decrease in motility of the separated sperm can be prevented; and an artificial insemination method, and an in vitro fertilization method. The method for separating mammalian sperm includes incubating the sperm in a medium containing a TLR7 ligand, and separating them into sperm floating in the upper layer and sperm sinking in the lower layer of the medium. The artificial insemination and in vitro fertilization methods include artificial insemination or in vitro fertilization for a non-human mammal using sperm of the non-human mammal separated by the method for separating mammalian sperm.

  • Patent number: 12084835
    Abstract: A remote operation device and a remote operation system that can reduce or eliminate deviation of the position of an indicator image of a working unit such as a line image in an image with respect to the position of the working unit in a real space. In some case, because of a cause such as a communication failure, a position posture coordinate value of a working unit corresponding to captured image data in a work environment image deviates from a position posture coordinate value of the working unit estimated according to an operation form of a remote operation mechanism. In this case, a semitransparent indicator image Img2(?2) simulating a bucket is superimposed on a work environment image Img1(?2) in a position where the bucket is estimated to be originally present and deviating from an image region representing the bucket.

  • Patent number: 11788076
    Abstract: The present disclosure provides a technique whereby the influence of an endogenous TCR is eliminated in TCR gene transfer. A TCR gene is edited using a genome editing enzyme, said genome editing enzyme having one characteristic that amino acids at two specific positions in DNA-binding modules contained in a DNA-binding domain thereof show repeating patterns which differ from one module to another among the four DNA-binding modules. Thus, a lowering in the expression efficiency of the transferred TCR caused by mispairing with an endogenous TCR and the occurrence of a self-reactive TCR are avoided.
