OBJECTIVES A diagnostic technique to objectively determine coronary in-stent stenosis was developed with multi(16)-slice computed tomography (MSCT), and it was compared with coronary angiography (CAG) in clinical cases. BACKGROUND MSCT is expected to replace coronary angiography as a new non-invasive examination. Evaluation of highly calcified or in-stent(More)
BACKGROUND Although oxidative stress by accumulation of reactive oxygen species (ROS) in diabetes has become evident, it remains unclear what genes, involved in redox balance, would determine susceptibility for development of atherosclerosis in diabetes. This study evaluated the effect of genetic polymorphism of enzymes producing or responsible for reducing(More)
Filling defects of the left atrial appendage (LAA) on multidetector computed tomography (MDCT) are known to occur, not only due to LAA thrombi formation, but also due to the disturbance of blood flow in the LAA of patients with atrial fibrillation (AF). The purpose of this study was to evaluate the impact of the maintenance of sinus rhythm via ablation on(More)
BACKGROUND Late gadolinium enhancement (LGE) of cardiac magnetic resonance imaging (MRI) represents myocardial fibrosis and may be related to the clinical outcome of various heart diseases. This study evaluated the relationship between LGE and cardiac events in hypertrophic cardiomyopathy (HCM) using a new scoring method. METHODS AND RESULTS This study(More)
Despite attempts in a number of studies to utilize muscle tissue and cells as microactuators, all of the biohybrid microdevices have been operable only in the culture medium and none have worked in air due to the dry environment. This paper demonstrates an atmospheric-operable bioactuator (AOB) fabricated by packaging an insect dorsal vessel (DV) tissue(More)
We propose a novel method for measuring the total radiated power (TRP) of small radio terminals, such as mobile phones, active RFID tags, and UWB devices, using a spheroidal cavity coupler in which an equipment under test (EUT) and a receiving antenna are displaced symmetrically around the focal points of the spheroid. The proposed method provides a(More)
Remakable progress has recently been made in the gastr ic punch biopsy under direct vis ion through the fiberscope, however, some tequnical problems are confronted today so far as usage of the forceps punch biotom. F i r s t difficulty to be solved is the mechanical l imitat ions due to the b io tom; good speciemens can only be obtained when the gast r ic(More)
