Miyashita A, Maekawa M, Shimoyama Y, Seko N, Kawasuso A, Umetsu R
J Phys Condens Matter . 2021 Oct; 34(4). PMID: 34695811
CoMnGa is a Weyl semimetal exhibiting giant anomalous Hall and Nernst effects. Using spin-polarized positron annihilation spectroscopy, we examined a Bridgman-grown CoMnGa single crystal with a nearly perfect2-ordered structure and...

Otsuka S, Ebata T, Yokoyama Y, Igami T, Mizuno T, Yamaguchi J, et al.
Br J Surg . 2019 Aug; 106(11):1504-1511. PMID: 31386198
Background: Differentiation between perihilar cholangiocarcinoma (PHCC) and benign strictures is frequently difficult. The aim of this study was to investigate the incidence and long-term outcome of patients with tumours resected...

Otsuka S, Ebata T, Yokoyama Y, Mizuno T, Tsukahara T, Shimoyama Y, et al.
Br J Surg . 2019 Mar; 106(6):774-782. PMID: 30889275
Background: Little is known about the effect of additional resection for a frozen-section-positive distal bile duct margin (DM) in perihilar cholangiocarcinoma. Methods: Patients who underwent surgical resection for perihilar cholangiocarcinoma...

Shinohara K, Ebata T, Shimoyama Y, Nakaguro M, Mizuno T, Matsuo K, et al.
Br J Surg . 2019 Jan; 106(4):427-435. PMID: 30675908
Background: The T system for distal cholangiocarcinoma has been revised from a layer-based to a depth-based approach in the current American Joint Committee on Cancer (AJCC) classification. In perihilar cholangiocarcinoma,...

Kasahara S, Yamashita T, Shi A, Kobayashi R, Shimoyama Y, Watashige T, et al.
Nat Commun . 2016 Oct; 7:12843. PMID: 27687782
The physics of the crossover between weak-coupling Bardeen-Cooper-Schrieffer (BCS) and strong-coupling Bose-Einstein condensate (BEC) limits gives a unified framework of quantum-bound (superfluid) states of interacting fermions. This crossover has been...

Tokiwa Y, Yamashita T, Udagawa M, Kittaka S, Sakakibara T, Terazawa D, et al.
Nat Commun . 2016 Feb; 7:10807. PMID: 26912080
The low-energy elementary excitations in frustrated quantum magnets have fascinated researchers for decades. In frustrated Ising magnets on a pyrochlore lattice possessing macroscopically degenerate spin-ice ground states, the excitations have...

Shimizu Y, Shimoyama Y, Kawada A, Kusano M, Hosomi Y, Sekiguchi M, et al.
J Biol Regul Homeost Agents . 2014 Oct; 28(3):433-42. PMID: 25316130
Pirfenidone is an antifibrotic agent for patients with pulmonary fibrosis, but this drug has adverse gastrointestinal (GI) effects. The first aim of this study was to assess GI symptoms due...

Kuribayashi S, Iwakiri K, Kawada A, Kawami N, Hoshino S, Takenouchi N, et al.
Neurogastroenterol Motil . 2014 Oct; 27(2):188-94. PMID: 25271562
Background: Recently reported normal values for esophageal motility obtained by high-resolution manometry (HRM) using a system with a Unisensor catheter were significantly different from those obtained by the ManoScan(®) ,...

Sumigama S, Sugiyama C, Kotani T, Hayakawa H, Inoue A, Mano Y, et al.
BJOG . 2014 Mar; 121(7):866-74. PMID: 24666658
Objective: To clarify the effects of uterine myometrial suture techniques at prior caesarean section on the incidence of pathologically diagnosed placenta accreta in placenta praevia with prior caesarean section (PPPC)....

Matsumoto N, Ebata T, Yokoyama Y, Igami T, Sugawara G, Shimoyama Y, et al.
Br J Surg . 2014 Jan; 101(3):261-8. PMID: 24399779
Background: Right-sided hepatectomy is often selected for perihilar cholangiocarcinoma because the extrahepatic portion of the left hepatic duct is longer than that of the right hepatic duct. However, the length...
