Leukocytapheresis (LCAP), performed with a leukocyte removal filter, was administered five times, at 1-week intervals, for 5 weeks of intensive therapy and five times, at approximately 1-month intervals, for approximately 5 months of maintenance therapy, to 13 patients with inflammatory bowel disease (IBD) diagnosed as ulcerative colitis (UC) in 8 and(More)
A 58-year-old man with subacute fulminant onset of autoimmune hepatitis (AIH) was treated by leukocytapheresis (LCAP) and bilirubin adsorption therapy (BAT), rather than by administration of highdose corticosteroids as he had mild glucose intolerance, and a definitive diagnosis of AIH was not obtained on admission; further, there was a risk of viral(More)
The developing heart and great vessels undergo drastic morphogenetic changes during the embryonic period. To analyze the normal and abnormal development of these organs, it is essential to visualize their structures in three and four dimensions, including the changes occurring with time. We have reconstructed the luminal structure of the hearts and great(More)
We present a computer-oriented method of producing pictures of Bers embeddings of the Teichmüller space of once-punctured tori. The coordinate plane is chosen in such a way that the accessory parameter is hidden in the relative position of the origin. Our algorithm consists of two steps. To each point in the coordinate plane, we first compute the(More)
The twisted Alexander polynomial was introduced by Lin [9] and Wada [18] independently. Lin defined it for a knot by using a regular Seifert surface and Wada defined it for a finitely presentable group by using Fox’s free differential calculus. More generally, Jiang and Wang [3] studied twisted topological invariants for a 3–manifold by using(More)
We propose a method of extracting scallop areas from gravel seabed images to assess fish resources, and developed an automatic system that measures their quantities, sizes, and states. Scallops feature different colors, fluted patterns and forms. The present study is described our method of extracting these features, and presented the results and its(More)
