Abstract: A camera can perform two different photographing operations with a lens at different positions without vignetting while preventing entry of light and dust. A camera includes a frame including a film compartment to contain a photographic film and a barrel extending from the film compartment in an optical axis direction, and a lens barrel movable in the barrel in X-direction. The lens barrel includes cylinders movable frontward relative to the barrel, and a cylinder movable frontward relative to the cylinder. The camera includes a rear bellows connecting the frame and the cylinder, and a front bellows connecting the cylinder and the cylinder. In a first photographing state in which the cylinders extend frontward relative to the barrel and the cylinder is accommodated inside the cylinder, the rear bellows is expanded and the front bellows is partially contracted. In a second photographing state, the cylinder extends frontward relative to the cylinder.

Abstract: A control device defines, for three-dimensional blood vessel data of a blood vessel corresponding to a branched center line, a cylindrical coordinate system, thereby converting this into blood vessel data in an orthogonal coordinate system. The control device uses a coordinate value of the coordinate axis in a radial direction at a first coordinate value of the coordinate axis in a center line direction and a coordinate value of the coordinate axis in the radial direction at a second coordinate value of the coordinate axis in the center line direction, thereby interpolating a coordinate value of the coordinate axis in the radial direction between the first coordinate value and the second coordinate value. The control device converts, after interpolation, the blood vessel data into blood vessel data in the cylindrical coordinate system.

Abstract: A stent (1) comprising a hoselike body obtained by braiding a multiplicity of thin wires (2) of superelastic metal into plaited form. In the longitudinal intermediate portion of the hoselike body, mutually neighboring individual thins wires (2) of superelastic metal are in contact with each other or close to each other with a minute interspace and are formed into a thin wire densely braided hose portion (3) with a length needed to block any opening of blood vessel dilation. At both side portions thereof, mutually neighboring individual thin wires (2) of superelastic metal are formed into a thin wire coarsely braided hose portion (4) provided with an interstice allowing passage of blood flow. The hoselike body when pulled in the longitudinal direction causes the individual thin wires (2) of superelastic metal to stretch into fine gathering, and when released from pulling can make resilient restoration to the original hoselike body.

Abstract: A method for efficiently amplifying abnormal prion protein (PrPSc) derived from bovine spongiform encephalopathy (BSE) is provided. Ultimately, the invention aims at eradicating the transmission of a prion disease by detecting a BSE-infected cow early and developing a method for inactivating prions and permitting early examination of prion inactivation. Provided is a method for efficiently amplifying PrPSc derived from BSE, wherein the method is based on a PMCA (protein misfolding cyclic amplification) method in which normal prion protein (PrPC) is used as a source and PrPSc is used as a seed, and PrPSc derived from BSE is amplified by stir-mixing, incubating, and sonicating both the PrPC and the PrPSc repeatedly, and wherein the method includes performing stir-mixing-incubation-sonication in the presence of a polysaccharide sulfate.
