Abstract: A robot system includes a robot, and an information processing portion. The information processing portion is configured to obtain a learned model by learning first force information about a force applied by a worker to a workpiece, first position information about a position of a first portion of the worker, and first workpiece information about a state of the workpiece, and control the robot on a basis of output data of the learned model.

Abstract: The present invention provides a method of quickly and accurately detecting and/or assaying an antigen using fluorescence correlation spectroscopy (FCS), which involves a fluorescence-labeled antibody fragment and a non-fluorescence-labeled intact antibody that form a complex with the antigen. There is a significant difference in diffusion rate between the fluorescence-labeled antibody fragment not bonded to the antigen and the complex formed by the the fluorescence-labeled antibody fragment, the antigen, and the non-fluorescence-labeled intact antibody, and this diffusion rate can be determined using FCS. The antigen can be an antigenic protein, such as an abnormal prion or a harmful protein contained in a food material. According to this method, antigens over a wide scope can be assayed regardless of the shape or molecular weight.

Abstract: A monoclonal antibody which recognizes abnormal type prion protein alone is disclosed. By the present invention, an anti-abnormal type prion monoclonal antibody whose corresponding antigen is an abnormal type prion protein, and which does not substantially react with normal type prion protein was first provided. Since the corresponding antigen of the monoclonal antibody according to the present invention is the naturally occurring abnormal type prion protein, measurement of the abnormal type prion protein may be attained with high sensitivity.

Abstract: It is intended to provide a drug which is efficacious in treating a prion disease and has a high safety. A remedy for a prion disease which contains a mesenchymal stem cell as the active ingredient and a method of producing the same. A remedy for a prion disease which contains a mesenchymal stem cell, in particular, a mesenchymal stem cell having an anti-prion antibody gene transferred thereinto as the active ingredient and a method of producing the same. These remedies can not only prevent the progress of a prion disease but also contribute to the recovery of nerve dysfunction caused by the disease.
