BACKGROUND/AIM To preserve pancreatic function, segmental pancreatectomy has been proposed for benign or low-malignancy tumors in the pancreatic body. Indications for the procedure, however, are still controversial. METHODS In this study, we investigated the advantages and disadvantages of segmental pancreatectomy compared with distal pancreatectomy and(More)
OBJECTIVE To investigate the role of Nrf2 in the pathogenesis of hepatic ischemia-reperfusion (I/R) injury. BACKGROUND Hepatic I/R injury is a serious complication that leads to liver failure after liver surgery. NF-E2-related factor 2 (Nrf2) is a transcription factor that plays a critical role in protecting cells against oxidative stress. Therefore, it(More)
BACKGROUND Whether hepatic resection is indicated for elderly patients with hepatocellular carcinoma (HCC) remains controversial. METHODS This retrospective study evaluated surgical outcomes and prognostic factors in elderly patients with HCC who underwent hepatectomy. Overall survival rates and disease-free survival rates after hepatectomy were compared(More)
We used positron emission tomography with 2-deoxy-2-[(18)F]fluoro- d-glucose (FDG-PET) in the diagnosis of two cases of malignant intraductal papillary mucinous tumor (IPMT) of the pancreas. A 56-year-old man and a 72-year-old man, both with tumors in the pancreatic head, were referred to Akita University Medical Center. Computed tomography revealed tumors(More)
BACKGROUND Sarcomatous intrahepatic cholangiocarcinoma (ICC) is a rare histological variant of ICC. The prognosis of sarcomatous ICC is poorly understood. METHODS We analyzed the prognosis of sarcomatous ICC by reviewing the previous reports and our own case. RESULTS Only 15 cases of sarcomatous ICC have been reported in the English-language literature(More)
This 10-b 50-MSamples/s SAR analog-to-digital converter (ADC) features on-chip digital calibration techniques, comparator offset cancellation, a capacitor digital-to-analog converter (CDAC) linearity calibration, and internal clock control to compensate for PVT variations. A split-CDAC reduces the exponential increase in the number of unit capacitors needed(More)
Toxins in shellfish, which are responsible for paralytic poisonings, undergo reductive transformation when incubated with the homogenate of various portions of the scallop, Placopecten magellanicus. The transformation includes the reductive elimination of O-sulfate groups, a change that is most evident in the locomotor tissue homogenates. The commercially(More)
OBJECTIVES Smokers with acute myocardial infarction have lower mortality rates than non-smokers despite increased risk for coronary artery disease. This study assessed the effects of smoking on complications and outcomes after acute myocardial infarction, and investigated the relationship between the clinical factors and the paradoxical effects of smoking(More)
We describe a patient with a ruptured and rapidly enlarging secondary tumor of the liver metastasized from an alpha-fetoprotein (AFP)-producing gastric cancer. The ruptured liver metastasis was successfully treated by transarterial embolization (TAE) followed by hepatic resection. A 65-year-old woman was admitted to our hospital with residual gastric(More)
