Fabrication of 1 T Bi-2223 Superconducting Magnet with 92 mm Bore Diameter at 77 K

A Bi-2223 superconducting magnet for practical use in liquid nitrogen is designed and fabricated. Bi-2223 tapesprepared by ConTrolled Over Pressure (CT-OP) process are used for the winding, and the critical current at 77.3 K and self-field is in the range of 174–185 A. 28 double-pancake coils are resistively connected in series by copper terminals. Highcritical current tape is used for top and bottom double-pancake coils, since the magnetic field normal to the tape surface ishighest at the top and bottom of the magnet. Two iron plates at top and bottom of the magnet are used for reduction of thenormal component of magnetic field to the Bi-2223 tape, since the total performance of the magnet is determined by theminimum critical current at maximum normal magnetic field component to the tape. The inner bore diameter of the magnetis 92 mm. And the homogeneity of magnetic field of long-axis direction in 50 mmφ × 100 mm length is within 3%. Themaximum magnetic field at the center of the bore is over 1.0 T at 77.3 K.Proceedings of the Cryogenic Engineering Conference (2013) , June 17–21, 2013, Anchorage, Alaska, US

Lethal Bleeding from a Duodenal Cancerous Ulcer Communicating with the Superior Mesenteric Artery in a Patient with Pancreatic Head Cancer

Pancreatic cancer often invades the duodenum and causes obstruction, but rarely causes massive duodenal bleeding. A 68-year-old male was admitted to our hospital because of vomiting. Enhanced abdominal CT showed a hypovascular tumor with air bubbles in the uncinate process of the pancreas. The tumor invaded the duodenum and metastasized to the liver and peritoneum. The main trunk of the superior mesenteric artery (SMA) was circumferentially involved. After admission, he had hematemesis and melena. Emergency gastroduodenoscopy revealed pulsating vessels in the third portion of the duodenum and he eventually experienced hemorrhagic shock. Severe bleeding occurred from his mouth and anus like a catastrophic flood. It was difficult to sustain blood pressure even with massive blood transfusion with pumping. After insertion of an intra-aortic balloon occlusion catheter, the massive bleeding was eventually stopped. Although we attempted interventional radiography, aortography revealed direct communication between the main SMA trunk and the duodenal lumen. The tumor was considered anatomically and oncologically unresectable. Thus, we did not perform further intervention. The patient died 2 h after angiography. Herein, we report the case of pancreatic head cancer causing lethal bleeding associated with tumor-involved SMA. Duodenal bleeding associated with pancreatic cancer invasion should be considered as an oncogenic emergency

The Japanese Clinical Practice Guideline for acute kidney injury 2016

Acute kidney injury (AKI) is a syndrome which has a broad range of etiologic factors depending on different clinical settings. Because AKI has significant impacts on prognosis in any clinical settings, early detection and intervention are necessary to improve the outcomes of AKI patients. This clinical guideline for AKI was developed by a multidisciplinary approach with nephrology, intensive care medicine, blood purification, and pediatrics. Of note, clinical practice for AKI management which was widely performed in Japan was also evaluated with comprehensive literature search
