The purpose of this study is to evaluate the accuracy of mammography, ultrasonography, and contrast-enhanced magnetic resonance imaging for the diagnosis of intraductal spread of breast cancer following preoperative neoadjuvant chemotherapy. We evaluated a total of 168 areas of normal breast tissue outside the mass in 42 consecutive female patients with(More)
Between August 1989 and September 1999, breast-conservation treatment (BCT) was performed in 250 of 256 breast cancer patients. Five of the 250 patients had bilateral breast cancer, and 4 with synchronous bilateral breast cancer of the 5 were concomitantly treated by chemo-endocrine therapy before simultaneous breast-conservation surgery for bilateral(More)
An elderly patient with breast cancer received toremifene monotherapy for one year, and about 60% tumor remission rate was obtained. Since viability of the residual tumor was suspected on ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI), lumpectomy was performed under local anesthesia. The histopathological diagnosis was(More)
We have been developing a novel human-friendly/cooperative work support robot. This system named PaDY (in-time Parts/tools Delivery to You robot) supports worker by delivering parts and tools to worker based on statistical analysis of the worker's work in an automobile assembly line to reduce the worker's physical workload and improve work efficiency. So(More)
We demonstrate an oral scientific simulation and its visualization based on E-science. This oral scientific application will become an essential key component for medical and dental clinic in the near future because Bio-Medical simulations will provide a clinical index considering a prognostic of a disease. In this case, it was shown that the physical(More)
This paper presents a phase retrieval method for digital holography with two high-speed cameras in particle measurement. The conditions for recording two holograms are derived theoretically. We focus in particular on the distance between the two holograms. The relative misalignment of the two holograms is also evaluated by numerical simulations. Finally, we(More)
When 50 mg CS-518, a novel thromboxane (TX) A2 synthase inhibitor, was orally administered to healthy male volunteers, the plasma concentration of CS-518 peaked after 0.5 h and then decreased with a half-life of 0.44 h. There was no significant change in the plasma concentration of circulating TXB2, whereas that of circulating 11-dehydrothromboxane B2(More)
