The data from the Visible Human Project (VHP) and the Chinese Visible Human (CVH), which are the serially sectioned images of the entire cadaver, are being used to produce three-dimensional (3D) images and software. The purpose of our research, the Visible Korean Human (VKH), is to produce an enhanced version of the serially sectioned images of an entire(More)
The purpose of this research is to enable users to semiautomatically segment the anatomical structures in magnetic resonance images (MRIs), computerized tomographs (CTs), and other medical images on a personal computer. The segmented images are used for making 3D images, which are helpful to medical education and research. To achieve this purpose, the(More)

High resolution electron microscopy (HREM) coupled with energy dispersive X-ray microanalysis were used to investigate the morphogenesis of calcification in 28 explanted porcine bioprosthetic heart valves. Different morphology and compositions of calcific deposits were consistently observed in various valvular structures of all explanted porcine(More)

High-resolution scanning electron microscopy (HR-SEM) combined with scanning tunneling microscopy (STM) was used to investigate the calcification mechanism occurring in the porcine bioprostheses implanted into the human heart. Eleven explanted porcine heart valves obtained during open heat surgery were prepared for HR-SEM and STM observations. HR-SEM(More)
Two methods have been developed for the detection of DNA immobilized on the surface of microtiter wells. An intercalating dye, 3,6-diaminoacridine, is used in stain and rinse solutions, so that measured absorbance values (450 nm) reflect the sum of DNA-bound and free dye. With diaminoacridine, signal increases of 0.056 +/- 0.010 were achieved on(More)
