We have used Heidenhain-pouch dogs to investigate the effects of (+/-)-5-methoxy-2-{[(4-methoxy-3,5-dimethylpyrid-2-yl)methyl]sulph inyl}-1H-imidazo[4,5-b]pyridine (TU-199), an imidazopyridine derivative, on gastric acid secretion stimulated by histamine, carbachol and tetragastrin. We have also investigated the duration of the antisecretory effect of(More)
OBJECTIVES This study was conducted to examine the relationship between provoked coronary spasm and clinical course in patients with acute myocardial infarction (AMI). BACKGROUND Coronary spasm has a pathogenetic role in the occurrence of AMI and progressive atherosclerosis. There is no report that focused on the prognostic significance of provoked(More)
—This study proposes a method for detecting the position of an object indoors using visible light communication and dead reckoning. More specifically, we first obtain positional information using visible light communication and then use dead reckoning. At the start point, where a visible light signal can be received, we detect the absolute position of the(More)
OBJECTIVE Significant Q-wave is sometimes invisible in the patients with triple vessel disease (TVD) even though TVD is a serious coronary heart disease. We offer the preliminary method to analyze the time-frequency profile of QRS in TVD patients. METHODS Electrocardiograms (ECG) band-pass filtered through 50 to 300Hz were recorded from the persons(More)
BACKGROUND The distribution of frequency power (DFP) within the QRS complex (QRS) is unclear. This study aimed to investigate the DFP within the QRS in ischemic cardiomyopathy (ICM) with lethal ventricular arrhythmias (L-VA). A computer simulation was performed to explore the mechanism of abnormal frequency power. METHODS The study included 31 ICM(More)
