p < 0.05). Among TNM stage III patients, a significant difference in survival was observed between surgical bypass associated with IORT and bypass alone ( p < 0.05); the median survival time of the IORT group was 10 months, whereas that of the control group was 5 months. In addition, HFS of 3 months or longer was achieved in 83.3% of patients who underwent… (More)

The patient was a 68-year-old woman who had cecal cancer with para-aortic lymph node metastases. Ileocecal resection was performed palliatively. Since metastasis to cervical vertebrae was detected after the operation, she received radiation therapy of 14 Gy to improve neck pain. Chemotherapy with TS-1 (80 mg/day) was started on an outpatient basis (4 weeks… (More)

On the assumption that the ulcerogenesis in Crohn's disease is closely linked with intestinal ischemia, we studied the pattern of vascular reaction of resected specimen using the technic of histometry. The atrophy of media in peripheral arterioles, indicating the presence of ischemia was notable not only in Crohn's disease but also in other benign bowel… (More)

For an algebraically closed field K with ch(K) = 2, let OM (1, SO(n, K)) denote the moduli space of holomorphic bundles on P 2 with the structure group SO(n, K) and half the first Pon-tryagin index being equal to 1, each of which is trivial on a fixed line l ∞ and has a fixed holomorphic trivialization there. In this paper we determine the Chow ring of OM… (More)

Let RX l k,n be the space consisting of all (n + 1)–tuples (p 0 (z),. .. , p n (z)) of monic polynomials over R of degree k and such that there are at most l roots common to all p i (z). In this paper, we prove a stable splitting of RX l k,n .

The purpose of this article is to (1) define M (t, k) the t-fold center of mass arrangement for k points in the plane, (2) give elementary properties of M (t, k) and (3) give consequences concerning the space M (2, k) of k distinct points in the plane, no four of which are the vertices of a parallelogram. The main result proven in this article is that the… (More)

The homology of spaces of polynomials with roots of bounded multiplicity YASUHIKO KAMIYAMA Let P l k,n be the space consisting of monic complex polynomials f (z) of degree k and such that the number of n–fold roots of f (z) is at most l. In this paper, we determine the integral homology groups of P l k,n .
