Preoperative evaluation of submucosal invasive colorectal cancer using a 15-MHz ultrasound miniprobe.

• Naoshige Harada, Shigeyuki Hamada, +7 authors Hiroshi Nawata
• Endoscopy
• 2001

BACKGROUND AND STUDY AIMS Recently, it was reported that focal submucosal invasive colorectal cancer could be treated by polypectomy or endoscopic mucosal resection (EMR) because of the rarity of… (More)

Pre-operative staging of ampullary tumours by endoscopic ultrasound.

• H. Kubo, Yoshiro Chijiiwa, Keiichi Akahoshi, Shigeyuki Hamada, Naotaka Matsui, Hiroshi Nawata
• The British journal of radiology
• 1999

Ampullary carcinomas have a significantly higher resectability rate and better prognosis than other periampullary carcinomas, although the prognosis is poor with advanced disease. Accurate tumour… (More)

Two endothelin receptors (ETA and ETB) expressed on circular smooth muscle cells of guinea pig cecum.

• Haruumi Okabe, Yoshiro Chijiiwa, +4 authors Hiroshi Nawata
• Gastroenterology
• 1995

BACKGROUND/AIMS The functional receptors for endothelin (ET) in colonic smooth muscle are still unknown. This study investigated the expression of ET receptors in isolated circular smooth muscle… (More)

CD146 attenuation in cancer-associated fibroblasts promotes pancreatic cancer progression.

• Biao Zheng, Kenoki Ohuchida, +10 authors Masao Tanaka
• Molecular carcinogenesis
• 2016

Cancer-associated fibroblasts (CAFs) are heterogeneous cell populations that influence tumor initiation and progression. CD146 is a cell membrane protein whose expression has been implicated in… (More)

Direct contractile effect of endothelin-1 on isolated circular smooth muscle cells of guinea pig caecum.

• Haruumi Okabe, Yoshiro Chijiiwa, Mitsuhiro Yoshinaga, Tomoko Misawa, Teppei Kabemura, Hiroshi Nawata
• Digestion
• 1995

Smooth muscle cells isolated from the circular muscle layers of the guinea pig caecum were used to determine whether endothelin-1 (ET-1) can cause contraction by exerting a direct action on smooth… (More)

Preoperative evaluation of gastric cancer by endoscopic ultrasound.

• Keiichi Akahoshi, Tomoko Misawa, +4 authors Hiroshi Nawata
• Gut
• 1991

The preoperative use of endoscopic ultrasound was evaluated in 74 patients with confirmed gastric cancer. It was used in diagnosing the depth of invasion in the gastric wall, the infiltration to the… (More)
