Congenital Web-like Tracheal Stenosis Cured Surgically in Adult
A 60-year-old, Japanese woman, with congenital web-like tracheal stenosis surgically treated. Successful relief from tracheal stenosis was obstained. Detection in adulthood and chance of the treatment for congenital tracheal stenosis is very rare. As far as this case is concerned, delay in detection and treatment is discussed of congenital tracheal stenosis
Assessment of contamination using an ATP bioluminescence assay on doorknobs in a university-affiliated hospital in Japan
An automated three-dimensional internal structure observation system based on high-speed serial sectioning of steel materials
For three-dimensional observation of the internal structure of hard materials, we developed an automated system based on serial sectioning with precision cutting and optical microscopy. The elliptical vibration cutting device in the system created mirrored surfaces suitable for optical microscopy during the serial sectioning of steel materials. In this study, high-speed sectioning with several micron thickness and repeated precise machining to depths of up to around 1 mm were achieved with a flat-edge cutting tool. For a 3 x 3 mm area of bearing steel, a mirrored surface could be created in about 1 minute, and 400 serial sectioning images were obtained within 7 hours without additional machining processes such as cleaning or changing of tools. The three-dimensional shapes and positions of continuously distributed inclusions found deep within the bearing steels, as well as cracks originating from these inclusions, could be detected with resolutions as high as 80 x 80 nm and in a wide field of view using this system
