The histogenesis of carcinosarcomas (malignant mullerian mixed tumors) of the female genital tract is still not completely understood. In the present study, several different molecular pathologic techniques were applied to determine the histogenesis of 15 uterine and ovarian carcinosarcomas. The patterns of X-chromosome inactivation and the presence of p53(More)
A 32-year-old pregnant female was admitted to our hospital at 32 week gestation and was scheduled for emergent cesarean section because of fetal distress. She had been suffering hydrodipsia and dry mouth, and had lost 4 kg in 2 weeks. Hypernatremia, hyperchloremia, and lower urinary specific gravity were preoperatively noted. Her electrolyte imbalance was(More)
As embedded systems have increasingly become multifunctional, it has become necessary to clarify what sorts of experiences the user can have through these functions. It is the system's user interface (UI) that leads this user experience, therefore, UI design has increased in importance. However, conventional development processes, often set the UI design(More)
In this paper, we propose a new version of noise reduction technique for speech degraded by environmental noise. The proposed method combines SPAC with spectral subtraction. Experiments are accomplished using continuous speech with several kinds of additive noise (white Gaussian, computer room and crowded hall). The output speech of the proposed method is(More)
An 82-year-old woman with severe tetanus was admitted to our ICU. Anti-convulsive treatment was started by continuous intravenous administration of midazolam followed by thiamylal. On day 15, thiamylal became insufficient to manage the spastic convulsion without frequent intravenous administration of other sedative and muscle relaxants. On day 16,(More)
We report abdominal bleeding caused by arteriovenous malformations (AVM) of the posterior gastric artery. A 38-year-old man visited our hospital complaining of epigastralgia. Enhanced abdominal CT revealed a high density spot in a huge low density mass. Angiographic study showed AVM of the posterior gastric artery. Transcatheter arterial embolization was(More)
We report a rare case of an intraductal papillary mucinous neoplasm (IPMN) with a pancreatobiliary-type carcinoma in situ (CIS) that originated around a mural nodule formed in a gastric-type adenoma. A 64-year-old man was admitted to our hospital in December 2001 for dilation of the main pancreatic duct, detected on abdominal ultrasonography.(More)
We experienced an internal jugular vein cannulation of a terminal life stage patient suffering from serious peritonitis carcinomatosa with severely edematous limbs. He could not lie down on a bed because of dyspnea due to high abdominal pressure caused by massive ascites. We examined his internal jugular vein with ultrasound device, and found that it kept(More)
