  • Publication number: 20100061986
    Abstract: The present inventors assessed the effect of anti-IL-6 receptor antibodies in suppressing chronic rejection reaction. They assessed the effect of anti-mouse IL-6 receptor antibody (MR16-1) administration in suppressing the chronic rejection reaction using a mouse model for post-heart-transplantation chronic rejection. The result of histopathological analysis of transplanted hearts extirpated 60 days after transplantation revealed that fibrosis of myocardium and vascular stenotic lesions, which are pathological conditions characteristic of the chronic rejection reaction, were significantly suppressed in the MR16-1-treated group as compared to the control group. Thus, MR16-1 administration was demonstrated to have the effect of suppressing chronic rejection reaction. Specifically, the present inventors discovered for the first time that the rejection reaction in the chronic phase after organ transplantation was suppressed by administering an anti-IL-6 receptor antibody.

  • Publication number: 20100001791
    Abstract: A current amplifying element that operates at a higher speed than conventional semiconductor devices is provided. An input current flows through an input current path 60 in a direction X, and a magnetic field generated from a magnet 90 is applied in a direction Z which is perpendicular to the direction X. An output current path 70 is formed under the input current path 60 with an insulator 80 interposed therebetween. Since the direction in which an output current flows is perpendicular to both the input current and the magnetic field, the current is amplified by the galvanomagnetic effects produced by the input current and the magnetic field.

  • Publication number: 20090303613
    Abstract: A variable focal length lens having a simple structure and capable of being used for applications requiring small size is provided, as well as a focal length adjusting device and an imaging device using the same. A variable focal length lens 10 has a lens 11, a positive electrode 13, and a negative electrode 14. A second layer 11b and a first layer 11a constituting the lens 11 are formed from polyvinyl chloride with which a plasticizer has been mixed. The hardness of these layers is adjusted by adjusting the mixing quantity, plasticizer type, or etc. The second layer 11b is formed so as so cover at least a light transmission region of the first layer 11a. When a voltage is applied between the positive electrode 13 and the negative electrode 14, the second layer 11 b and first layer 11 a are deformed to be pulled to the positive electrode 13, and thereby the curvature of the variable focal length lens 10 is varied to vary the focal length.
