The efficacy and safety of gemcitabine at a starting dose of 1,000 mg/m2 administrated once a week for 3 weeks with 1 week's rest was investigated in elderly 11 patients with unresectable pancreatic cancer. Objective response was not documented. However, pain intensity, analgesic consumption and Karnofsky Performance Status (KPS) were frequently improved.(More)
AIM   To follow up blood donors found with hepatitis C virus (HCV) infection, to improve the outcome by antiviral treatments. METHODS   Between 1991 and 2001, 3377 of the 1 925 860 donors (0.18%) were found to have HCV infection at the Hiroshima Red Cross Blood Center in Japan. Of them, 987 were able to be followed regularly over 9-18 years until 2009,(More)
In this article, we develop a distributed robotic system that can provide various services in a real environment using ad-hoc networked active radio frequency identifications (RFIDs). These services are derived from a large amount of data acquired from sensors connected to active RFIDs. The primary advantage of this method is that it facilitates the(More)
occurred already in 10 to 21 days in most cases and aggravation thereaf ter appeared to be extremely slow. On the other hand, no changes were seen in about one fourth of the cases. The reason for the rapid appearance of atrophy may be attributable to the circulatory disturbance of the mucosa due to surgery. No relationship was found between postoperative(More)
AIM To portray liver disease and project outcomes in carriers of hepatitis C virus (HCV) in the general population. METHODS Liver disease was evaluated in 1019 individuals who were found with HCV infection at blood donation, and they were followed for 5-10 years with or without receiving interferon (IFN). RESULTS At baseline, chronic hepatitis was(More)
We propose a path planning method to avoid moving obstacles only by steering. The method uses the tangent-arc-tangent-arc-tangent model to plan a path that satisfies two requirements: 1) the own vehicle modeled as a rigid body with a shape and direction doesn't collide with moving obstacles on the path (i.e., the path is collisionless); 2) the path takes(More)
In order to invest igate immune mechanism in pancreat i t is , following exper iments were tried. 1. Eleven ra ts were injected int raper i toneal ly 40 mg of dl-Ethionine every other day for 2 weeks. Serum amylase was elevated markedly and acinus of pancreas was fulled of zymogen granules. Latex agglutination tes t and double gel diffusion tes t were used(More)
