BACKGROUND AND METHODS The plasma cholesteryl-ester transfer protein (CETP) catalyzes the transfer of cholesteryl esters from high-density lipoprotein (HDL) to other lipoproteins. We recently described a Japanese family with increased HDL levels and CETP deficiency due to a splicing defect of the CETP gene. To assess the frequency and phenotype of this(More)
We describe a new low density lipoprotein (LDL) apheresis system using dextran sulfate cellulose column in an automated column regenerating unit (LDL continuous apheresis). Two columns containing 150 ml of dextran sulfate cellulose were used, and the whole extracorporeal circulation was about 400 ml in volume. After 600 ml of plasma was adsorbed into the(More)
Plasma high density lipoproteins (HDL) are a negative risk factor for atherosclerosis. Increased HDL is sometimes clustered in families, but a genetic basis has never been clearly documented. The plasma cholesteryl ester transfer protein (CETP) catalyses the transfer of cholesteryl ester from HDL to other lipoproteins and therefore might influence HDL(More)
OBJECTIVES We compared, on a site by site basis, the morphologic features of coronary calcifications determined by electron beam computed tomography (EBCT) and angiographically defined coronary atherosclerosis. BACKGROUND Quantification of coronary calcification using EBCT is clinically useful for the prediction of coronary stenosis. However, the relation(More)
Lipoprotein patterns and cholesteryl ester transfer activity (CETA) were examined in 2 patients with familial hyperalphalipoproteinaemia (FHALP). The proband was a healthy 58-year-old Japanese male who had an HDL cholesterol of 7.83 mmol/l (301 mg/dl). His sister's HDL cholesterol was 4.52 mmol/l (174 mg/dl), which suggested that both were homozygous(More)
Study of two families containing individuals with nephrogenic diabetes insipidus (NDI) indicated different types of 21.3 kb and 26.3 kb deletions involving the AVPR2 and ARHGAP4 (RhoGAP C1) genes. In the case of the 21.3 kb deletion, the deletion consensus motif (5'-TGAAGG-3') and polypurine runs, known as the arrest site of polymerase alpha, were detected(More)
To determine the prevalence of metabolic syndrome in the Japanese general population, we analyzed data from a nationwide survey conducted in 2000. According to the Japanese new diagnostic criteria for metabolic syndrome in 2005, we analyzed 3,264 people aged from 20 to 79 (men, 1,917; women, 1,347) from the total participants. The incidence of metabolic(More)
BACKGROUND There has not been a comparison of the electrocardiographic (ECG) finding of ST-segment elevation in the precordial leads in patients with takotsubo cardiomyopathy (TC) and those with anterior acute myocardial infarction (AMI), with regard to the location of the culprit lesion. METHODS AND RESULTS The present study evaluated 18 patients with(More)
The long-term efficacy and safety of HMG-CoA reductase inhibitors (statins) have been established in large multicenter trials. Inhibition of this enzyme, however, results in decreased synthesis of cholesterol and other products downstream of mevalonate, such as CoQ10 or dolichol. This was a randomized double-blind, placebo-controlled study that examined the(More)
