The nodal-related genes are well known for their fundamental roles during vertebrate development, including mesoderm induction, neural induction, and left-right axis formation, as several nodal-related genes show left-sided expression in mesodermal lineages. We have isolated the first non-vertebrate nodal-related gene, HrNodal, from the ascidian Halocynthia(More)
Background. Breast carcinoma and precancer are thought to start in the lining of the milk duct or lobule. While ductography has been advocated as the main procedure in patients with nipple discharge, fiberoptic ductoscopy (FDS) is an emerging technique allowing direct visual access to the ductal system of the breast through nipple orifice exploration.(More)
A case of malignant hemangioendothelioma (MH) of the small intestine in a 27-year-old woman is reported herein. The patient developed acute abdominal symptoms during investigations for anemia, weight loss, anorexia, and recurrent gastrointestinal bleeding. An emergency laparotomy revealed perforation of a jejumal tumor. The results of a histopathological(More)
A case of a solitary fibrous tumor (SFT) of the perianal region in a 62-year-old man is reported herein. The patient had undergone an abdominoperineal excision of the rectum for an anorectal tumor 13 years previously, and had been referred to our hospital for a perineal mass. Computerized tomography and angiography revealed a markedly hypervascular tumor(More)
A 56-year-old man who underwent a tooth extraction in the previous year presented with weakness of the right upper extremity. Brain CT and MRI scans showed subcortical hemorrhage in the left frontal lobe. His body temperature was 37.5°C. Blood examination revealed anemia, elevated levels of C-reactive protein, and a positive result for PR3-ANCA.(More)
Automatic layout algorithms, placement and routing, for function blocks of CMOS gate arrays are presented. The placement algorithm assigns transistors to basic cells so as to minimize the number of cells used and to minimize the number of interconnections crossing cut-lines. The former objective is achieved by finding a maximum matching and the latter is(More)
BACKGROUND Whether clinical characteristics and outcomes in patients suffering acute heart failure (AHF) vary according to the timing of hospital arrival is unclear. We aimed to evaluate differences between subjects presenting in the daytime and nighttime. METHODS A total of 679 patients with AHF were examined, classified into the two groups from the(More)
