In auction services such as eBay or yahoo, bidders can select interesting items from among many different items. It takes a long time, however, to investigate various items’ attributes, such as the price, the bids, and the time left. On the other hand, it is possible to circulate large quantities of rich content such as image data by using broadband(More)
PURPOSE AND EXPERIMENTAL DESIGN CDC25 genes are cell cycle-activating phosphatases that positively regulate the activity of cyclin-dependent kinase. CDC25A and CDC25B, being oncogenes, are overexpressed in a variety of human malignancies. To investigate the potential roles of CDC25s in hepatocellular carcinoma (HCC), expression of CDC25A and CDC25B was(More)
Hepatic resection has gained acceptance as the most effective therapy for liver metastases from colorectal cancer. Microwave coagulation therapy (MCT) and radiofrequency ablation as well as resection are also reported as effective therapies. We analyzed the prognosis of 52 patients with liver metastases from colorectal cancer treated with MCT as the first(More)
To evaluate the efficacy of microwave coagulation therapy (MCT) for liver metastases from colorectal cancer, we analyzed the survival and the disease-free survival rate. From 1990 to 2001, 18 patients with liver metastases measuring < or = 3 cm in diameter and number of metastases < or = 3 were treated with MCT. The 3- and 5-year survival rates were 62% and(More)
BACKGROUND The diminutive, flat depressed colorectal lesion is a possible precursor of early stage carcinoma. However, the significance of this lesion in colon carcinogenesis remains unclear. METHODS Eighty-one diminutive flat lesions (<5 mm diameter) with a central depression (DPdep) were resected colonoscopically and their molecular characteristics were(More)
BACKGROUND/PURPOSE The efficacy of intraoperative celiac plexus block was compared with that of pharmacological therapy in the treatment of pain caused by unresectable pancreatic cancer. METHODS Twenty-one patients were included in the study: 15 patients underwent intraoperative celiac plexus block (group 1) and 6 received pharmacological therapy (group(More)

The system extracts keywords from the content of the web page currently being viewed and retrieves the context of past web browsing related tothe keywords. We define the context as a sequence of web browsing when many web pages related to the keyword were(More)
The study subjects were 49 patients with hepatocellular carcinoma. Twenty-nine patients underwent hepatic arterial blood flow block via thrombosis of the cancer-bearing area with a gelatin sponge, while the other 20 patients underwent a combination of hepatic arterial block and partial blood flow block of the portal vein with a hepatic venous balloon.(More)
UNLABELLED We analyzed the clinicopathological factors in two cases of local recurrence after a disease-free interval (DFI) of more than 12 months following microwave coagulation therapy (MCT) for liver metastases from colorectal cancer. Case 1: A local recurrence was diagnosed at 14 months after MCT for a liver metastasis of 20 mm in diameter from rectal(More)
