We developed a new laparoscopic manipulator to substitute for the human assistant, which utilizes the property of oblique viewing laparoscopes. Instead of panning around the fulcrum to move the laparoscopic field of view to left/right in the case of the "straight-viewing" laparoscope, only the scope cylinder of the "oblique-viewing" laparoscope attached to(More)
Clinical studies have shown that oxaliplatin, a novel platinum derivative, is a potent chemotherapeutic agent for colorectal cancer when combined with 5-fluorouracil and leucovorin. Although the toxic activity is based on covalent adducts between platinum and DNA, its actual biological behavior is mostly unknown. In an effort to explore the mechanism of(More)
The structures of glycosphingolipids from highly purified colorectal cancer cells and normal colorectal epithelial cells of 16 patients have been analyzed in fine detail (Misonou Y, Shida K, Korekane H, Seki Y, Noura S, Ohue M, Miyamoto Y. 2009. Comprehensive Clinico-Glycomic Study of 16 Colorectal Cancer Specimens: Elucidation of aberrant glycosylation and(More)
This paper describes the development of a novel wearable laparoscope manipulator which is put on the surface of the patient's hypogastric region, using the artificial muscles. The manipulator was composed of a Stewart-Gough Platform with six degrees of freedom. This manipulator is compact and very lightweight. Its weight is 364g. This manipulator can be(More)
This paper describes a new proposal on the flexible authorization function based on the organizational hierarchy. We apply the function to a network monitoring system, which we have installed. Today's organization for the network administration at an institute has the hierarchical nature of a tree structure according to the inheriting responsibility of the(More)
BACKGROUND We herein report a case of a bronchogenic cyst arising from the esophagogastric junction treated by laparoscopic full-thickness extirpation. The full-thickness defect was closed by hand sewing a T-shaped line over the gastroendoscope as a bougie to prevent postoperative deformity or stenosis. Partial fundoplication (Toupet fundoplication) was(More)
We add flexibility to the authorization with Shibboleth by featuring a system managing additional attributes. The system offers an interface and a database to privileged administrators. When any temporary groups or projects are created, a proper set of users are assigned to them without modifying the IdP backends.
