Background—Cardiac myosin–induced myocarditis is an experimental autoimmune myocarditis (EAM) model used to investigate autoimmunological mechanisms in inflammatory heart diseases and resembles fulminant myocarditis in humans. We investigated the therapeutic role of thioredoxin-1 (TRX-1), a redox-regulatory protein with antioxidant and antiinflammatory(More)
call this mechanism double-screw-drive (DSD) mechanism. DSD mechanism was applied to a robotic forceps manipulator for laparoscopic surgery. In the first prototype, by adding the third linkage to DSD mechanism and rotating this, opening and closing motions of a gripper was attained. In the second prototype, DSD forceps manipulator was enhanced so that its(More)
BACKGROUND & AIMS Gut dysbiosis is closely involved in the pathogenesis of inflammatory bowel disease (IBD). However, it remains unclear whether IBD-associated gut dysbiosis contributes to disease pathogenesis or is merely secondary to intestinal inflammation. We established a humanized gnotobiotic (hGB) mouse system to assess the functional role of gut(More)
When a load is added to the tip of a wire actuated robotic forceps, tracking accuracy of the forceps is degraded due to the elastic elongation of the wire. In this paper, for the wire actuated robotic forceps, a new algorithm that can estimate a reaction torque and an amount of elongation of the wire, is proposed. By compensating for amount of elongation of(More)
法政大学大学院理工学研究科機械工学専攻修士課程 In this paper, the identification of finger operation and control of the fingers of a myoelectric prosthetic hand are discussed. Finger operation is classified into the six types of motion. On the basis of integrated electromyography (IEMG), the identification of finger operation is performed using a support vector machine based(More)
