Neurological disorders are the most unpredictable and feared complications after open surgery or endovascular aortic repair. Paraplegia because of spinal cord injury is well known after thoracoabdominal aortic surgery but not after valvular surgery.

The patient was a 76-year-old man with myasthenia gravis (MG). He suffered from a sudden back pain, and was diagnosed with Stanford type A acute aortic dissection. We performed emergency graft replacement of the ascending aorta under cardiopulmonary

Extravasation of prosthetic grafts is rare. Various anatomical problems after graft replacement might make standard endovascular treatment difficult. Use of a commercially available main body requires an adequate distance of the flow divider. An 86-y

A magnetic refrigerator that makes use of the magneto-caloric effect realizes a highly efficient cooling device. Since the cooling power of magnetic refrigerators depends largely on the strength of the magnetic field, the use of a superconducting mag

HoxEr1-xN (x=0.25, 0.5, 0.75) samples were synthesized by nitriding of HoxEr1-x alloy bars and their thermal conductivity κ were measured. The measured κ values were comparable to those of stainless steel and Er3Ni. Ho0.5Er0.5N showed the highest

A novel filling method of regenerator materials, which we name a co-axial layout , is experimentally investigated. The 2nd stage regenerator of a Gifford–McMahon cryocooler was packed with 50% by volume of the co-axial layout (low temperature side)

In order to improve the cooling power at 4.2 K, performance of a Gifford–McMahon cryocooler was investigated. We focus on regenerator materials and structure of 2nd stage regenerator. A ceramics regenerator of Gd 2 O 2 S (GOS) was used in the cold

Treatment of ischemic mitral regurgitation accompanied by strong tethering remains a challenge. Undersized ring annuloplasty is frequently associated with residual/recurrent mitral regurgitation caused by mitral-leaflet tethering. Although chordal cu
