New Application of Carbon Nanotubes. Migration Behavior of Sodium in Silicon Dioxide Films during Secondary lon Mass Spectrometry Analysis with a Sample Cooling System

Autor: Shun-ichi Hayashi, Masahiro Kudo, Reiko Saito

Publikováno v: Hyomen Kagaku. 21:584-589

The behavior of Na in SiO2 film during SIMS depth profiling was characterized by varying the sample temperature from 154 K to 303 K under the condition of self-compensation of charges. The depth distributions of the defects in the films were analyzed

Selective depletion of neutrophils by a monoclonal antibody, RP-3, suppresses dextran sulphate sodium-induced colitis in rats

Autor: Hideaki Takizawa, Hitoshi Asakura, Rintaro Narisawa, Katsutoshi Kawasaki, Keiichi Seki, Masaaki Natsui, Kazuhito Sugimura, Yasunobu Matsuda, Fujiro Sendo, Shun-ichi Hayashi

Publikováno v: Journal of Gastroenterology and Hepatology. 12:801-808

Administration of dextran sulphate sodium to animals induces acute colitis characterized by infiltration of large numbers of neutrophils into the colonic mucosa, which histologically resembles human active ulcerative colitis. It has been reported tha

Photoirradiation‐charge compensation for secondary ion mass spectrometers analysis of semiconductors

Autor: Yoshihiro Hashiguchi, Shun-ichi Hayashi

Publikováno v: Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films. 11:2610-2613

For secondary ion mass spectrometry (SIMS) analysis a photoirradiation‐charge compensation technique has proven to be very effective and useful in the analysis of semiconductor samples. The mechanism of charge compensation was also studied. Monochr

What is an appropriate indication for endoscopic papillary balloon dilation?

Autor: Keiichi Seki, Hitoshi Asakura, Hiroto Wakabayashi, Hirotaka Motoyama, Shinichi Itoh, Masaaki Natsui, Shun-ichi Hayashi, Rintaro Narisawa

Publikováno v: European journal of gastroenterologyhepatology. 14(6)

There are a number of views on the indication for endoscopic papillary balloon dilation (EPBD) in the management of bile duct stones. In this study, we have evaluated the efficacy and safety of EPBD compared with endoscopic sphincterotomy (EST).Prosp
