A method for obtaining electrocardiographic potential through thin cloth inserted between the measuring electrodes and the skin of a subject's dorsal surface when lying supine has been proposed. The method is based on capacitive coupling involving the electrode, the cloth, and the skin. Examination of a pilot device which employed the method revealed the(More)
Laparoscopic surgeons require extended experience of cases to overcome the lack of depth perception on a two-dimensional (2D) display. Although a three-dimensional (3D) display was reported to be useful over two decades ago, 3D systems have not been widely used. Recently, we developed a novel 3D dome-shaped display (3DD) system, CyberDome. In the present(More)
Aerial and land-based sighting surveys were conducted to clarify the distribution of Steller sea lions during winter in the northern Sea of Japan, along the west coast of Hokkaido, from 2001 to 2003. Aerial surveys revealed that sea lions gathered around the Rishiri-Rebun Islands in March 2002 and 2003, and between Iwanai and Cape Obana in February 2003.(More)
Modification and reuse of digital contents, particularly web data, has become easy due to advancement in computer technology. The work created by a person (or a group of persons) can be reused by another person (or group) for different purpose. Thus, there can be multiple copyright holders for the same information. In such scenario, it is important to(More)
We examined the effects of FK506, an immunosuppressive agent, on the genesis of water immersion stress-induced gastric lesions in rats. Using high-performance liquid chromatography, four kinds of prostaglandins, ie, 6-keto-prostaglandin F1α, prostaglandin F2α, prostaglandin E2, and prostaglandin D2, were detected, and no leukotrienes were detected in(More)
Pseudoaneurysm of the cystic artery is a cause of hemobilia, and is extremely rare, with only eight cases having been reported in the world literature. We report a case of pseudoaneurysm of the cystic artery in a 72-year-old Japanese man. The patient experienced epigastric pain and melena, and was found to have jaundice and liver dysfunction. Repeated(More)
Currently, there is no effective pharmacotherapy against exaggerated mobilisation of neutrophils in human airway diseases such as chronic obstructive pulmonary disease and asthma. We evaluated the effect of two synthetic vasoactive intestinal peptide (VIP)-like analogues on cytokine-induced neutrophil recruitment in airways in vivo. Recombinant interleukin(More)
The measurement of plasma concentrations of monoamine metabolites is a useful method for inferring the dynamics of monoamine metabolites in the brain. To clarify effects of age and sex on plasma monoamine metabolites levels, we used high-performance liquid chromatography to measure plasma levels of homovanillic acid (HVA), free and total(More)
We report two cirrhotic patients with gastric antral vascular ectasia (GAVE) in whom chronic blood loss presented a major problem. Case 1, a 69-year-old man, had alcoholic liver cirrhosis, and case 2, a 75-year-old woman, had liver cirrhosis associated with hepatitis C virus. The patients required repeated blood transfusions but still exhibited persistent(More)
A new system has been developed for obtaining electrographic potential through thin underwear inserted between the measuring electrodes and the skin of a neonate or an infant when lying supine. The system is based on capacitive coupling involving the electrode, the underwear, and the skin. Validation of the system revealed the following: (1) the signal(More)
