Abstract: The present invention provides a bispecific antibody and use thereof, and the bispecific antibody or an antigen-binding fragment of the present invention can bind to two or more antigens or two or more epitopes of a same antigen. The antibody or the antigen-binding fragment of the present invention can be used to treat a variety of diseases, such as inflammatory diseases, autoimmune diseases, cancers or spinal cord injury, and can also be used for diagnosis and prognosis of related diseases.

Abstract: The present invention is directed to a method and a device for long-term cryopreservation of a biological sample, including a vascularized tissue, an innervated tissue, or both, such, but not limited to a limb.

Abstract: A conveyor for an implant having at least one cavity, including a conveying handle, a conveying cable, and a core wire. The conveying cable is a tubular body, a proximal end of the core wire is connected to the conveying handle, and a distal end of the core wire penetrates a distal end of the conveying cable from a proximal end of the conveying cable; a first control is provided on the conveying handle, and when the implant is connected to the distal end of the conveying cable, the first control controls the distal end of the core wire to extend into the implant to straighten the curved implant, or the first control controls the core wire to withdraw from the implant to restore the implant to a preset shape. The conveyor can load and release the implant on the conveyor, and be used in the entire implanting process.

Abstract: Various embodiments of the present disclosure provide methods and apparatuses for asymmetric carrier bandwidth design. The method implemented at a network node comprising determining a message comprising a delta carrier center frequency shift parameter. The method implemented at a network node further comprises transmitting the message to at least one terminal device.
