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)
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 paper, we present a method to initialize at a feasible point and unfailingly solve a non-convex optimization problem in which a set-point motion is planned for a multi-link manipulator under state and control constraints. We construct an initial feasible solution by analyzing the final time effect for feasibility problems of flatness based motion(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)
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)
A 75-year-old woman was referred to our hospital for further examination of gastric antral abnormal endoscopic findings. Endoscopic study of the stomach revealed a depressed lesion in the gastric antrum. Atrophic findings were not recognized in the background gastric mucosa, and Helicobacter pylori infection was not detected by histology, an urea breath(More)
