In this paper, we present a computer-assisted automatic diagnostic system for lung cancer that detects nodule candidates at an early stage from helical CT images of the thorax. Our diagnostic system consists of analytical and diagnostic procedures. In the analytical procedure, first we extract the lung and the pulmonary blood vessel regions using the fuzzy(More)
A chimera based on the chicken alpha4 nicotinic acetylcholine receptor (nAChR) subunit containing an insert from loop B to the N-terminus of the Drosophila melanogaster Dalpha2 (=SAD) subunit was constructed and co-expressed with the chicken beta2 nAChR subunit in Xenopus laevis oocytes. The actions of the neonicotinoid insecticide imidacloprid were(More)
To achieve the complete three-dimensional (3-D) data retrieval of the shape of dentition, dental casts were measured from four directions; occlusal, right, left, and labial sides using a line laser scanner. Reconstruction of the entire shape, including undercuts and tooth crowding area, was attempted by applying a perceptual grouping algorithm, which is one(More)
The Cell Broadband Engine Architecture (CBEA) is a novel microprocessor architecture designed to provide power-efficient and cost-effective high-performance processing for some of the world's most demanding applications, including next generation game consoles. Applications that show special promise of benefiting from CBEA are medical imaging, security and(More)
Rats with dwarfism accompanied by skeletal abnormalities, such as shortness of the limbs, tail, and body (dwarf rats), emerged in a Jcl-derived Sprague-Dawley rat colony maintained at the Institute for Animal Experimentation, St. Marianna University Graduate School of Medicine. Since the dwarfism was assumed to be due to a genetic mutation based on its(More)
