Journal ArticleDOI
Reconsideration of Postoperative Oral Intake Tolerance After Pancreaticoduodenectomy: Prospective Consecutive Analysis of Delayed Gastric Emptying According to the ISGPS Definition and the Amount of Dietary Intake
Emi Akizuki,Yasutoshi Kimura,Takayuki Nobuoka,Masafumi Imamura,Minoru Nagayama,Tomoko Sonoda,Koichi Hirata +6 more
TL;DR: The ISGPS definition of DGE seemed feasible for patient management, and TDI values provided additional information for analyzing postoperative oral intake tolerance, especially when describing the differences among non-DGE patients.
Journal ArticleDOI
Detection of anti-livin antibody in gastrointestinal cancer patients.
Atsuhito Yagihashi,Koichi Asanuma,Naoki Tsuji,Toshihiko Torigoe,Noriyuki Sato,Koichi Hirata,Naoki Watanabe +6 more
TL;DR: Livin mRNA expression in gastrointestinal cancer cell lines and the prevalence of antibody responses against livin in patients with various gastrointestinal cancers are examined.
Journal ArticleDOI

TL;DR: Judging whether it is gallstone-induced or not is most urgent and crucial for deciding treatment policy including the assessment of whether endoscopic papillary treatment should be conducted or not.
Journal ArticleDOI
Clinical and immunological evaluation of anti-apoptosis protein, survivin-derived peptide vaccine in phase I clinical study for patients with advanced or recurrent breast cancer
Tetsuhiro Tsuruma,Yuji Iwayama,Tosei Ohmura,Tadashi Katsuramaki,Fumitake Hata,Tomohisa Furuhata,Koji Yamaguchi,Yasutoshi Kimura,Toshihiko Torigoe,Nobuhiko Toyota,Atsuhito Yagihashi,Yoshihiko Hirohashi,Hiroko Asanuma,Kumiko Shimozawa,Minoru Okazaki,Yasuhiro Mizushima,Naohiro Nomura,Noriyuki Sato,Koichi Hirata +18 more
TL;DR: The vaccination with survivin-2B peptide mixed with IFA increased the frequency of peptide-specific CTL more effectively than vaccination with the peptide alone, although neither vaccination could induce efficient clinical responses.
Journal ArticleDOI
Gene expression analysis identifies over-expression of CXCL1, SPARC, SPP1, and SULF1 in gastric cancer.
Siina Junnila,Arto Kokkola,Toru Mizuguchi,Koichi Hirata,Marja-Liisa Karjalainen-Lindsberg,Pauli Puolakkainen,Pauli Puolakkainen,Outi Monni +7 more
TL;DR: Comparative analysis between Finnish and Japanese datasets identified 58 common genes that were differentially expressed between cancerous and non‐neoplastic gastric tissues, including CXCL1, SPARC, SPP1, and SULF, which represent potential biomarkers for gastric cancer.
