The shortage of nurses in large hospitals of developed countries has become a major problem. Especially, the shortage of scrub nurses, who assist operating surgeons exchange surgical instruments, has been chronically severe. To compensate for this shortage, we have been proposing the scrub nurse robot (SNR) system that is capable of functioning as a skilled(More)
Recently, there have been reports of postnatal vasculogenesis in cases of ischaemia models. The aim of the present study is to provide evidence of postnatal vasculogenesis in breast-cancer-bearing mice. Based on cell surface antigen expression, we isolated endothelial precursor cells from bone marrow, peripheral blood and tumour-infiltrating cells from mice(More)
We recently established a new human inflammatory breast cancer (IBC) xenograft (WIBC-9) originating from a patient with IBC. The original tumor and WIBC-9 revealed invasive ductal carcinoma with a hypervascular structure of solid nests and marked lymphatic permeation in the overlying dermis. In the central part of the solid nests, vasculogenic mimicry,(More)
BACKGROUND Matrix metalloproteinase-9 (MMP-9) is one of the MMPs that play an important role in cancer invasion and metastasis. Increased levels of MMP-9 in tumor tissue have been found to correlate with advanced stages of colorectal cancer. However, the clinical significance of determining the levels of MMP-9 in blood samples from patients with colorectal(More)
INTRODUCTION Liver hemangiomas are the most common benign liver tumors, usually small in size and requiring no treatment. Giant hemangiomas complicated with consumptive coagulopathy (Kasabach-Merritt syndrome) or causing severe incapacitating symptoms, however, are generally considered an absolute indication for surgical resection. Here, we present the case(More)
INTRODUCTION Management of the biliary ducts during liver resection is one of the most important challenges for hepatobiliary surgeons. Here, we report the case of a left hepatic trisectionectomy for hilar cholangiocarcinoma with a rare aberrant biliary duct of segment 5, which, to the best of our knowledge, has never been reported in previous literature.(More)
To compensate for severe shortage of scrub nurses, we have been developing the Scrub Nurse Robot (SNR) system that is capable of functioning as a skilled human scrub nurse, who is able to accurately predict which surgical instrument a surgeon will request next and to give it to the surgeon without any delay. In order to achieve this accurate prediction, we(More)
