BACKGROUND A lectin-like oxidized low-density lipoprotein (LDL) receptor-1 (LOX-1) is the major receptor of oxidized LDL in endothelial cells. The expression of LOX-1 was shown to be upregulated in atherosclerotic lesions. Recently, LOX-1 gene polymorphism (G501C) was reported to be associated with myocardial infarction (MI). HYPOTHESIS Our study was(More)
Dietary flavonoid intake has been reported to be inversely associated with the incidence of coronary artery disease. To clarify the possible role of tea flavonoids in the prevention of atherosclerosis, we investigated the effects of tea flavonoids on the susceptibility of low-density lipoprotein (LDL) to oxidative modification. In an in vitro study,(More)
OBJECTIVE The acute effects of olive oil, milk fat and safflower oil on postprandial lipemia and remnant lipoprotein metabolism were investigated. METHODS Eight Healthy male volunteers randomly underwent three types of oral fat-vitamin A loading tests. The test drink was a mixture of retinyl palmitate (RP)(50,000 IU of aqueous vitamin A/m2 body surface(More)
Mutation frequencies in the beta 3-adrenergic receptor gene were measured in 83 CAD patients and 107 controls (all Japanese nationals) and the mutation incidence in the two groups was compared. The relationship between characteristics of lipid and glucose metabolism and presence or absence of the mutation was examined in CAD patients. The frequency of this(More)
OBJECTIVE The ATP-binding cassette transporter-A1 (ABCA1) regulates cholesterol efflux from cells and is involved in high-density lipoprotein metabolism and atherogenesis. The objective of this study was to investigate the effect of dexamethasone (Dex) and other glucocorticoid receptor (GR) ligands on apolipoprotein AI-mediated cholesterol efflux from(More)
OBJECTIVES We sought to elucidate the effects of 20-mg versus 5-mg atorvastatin on thoracic and abdominal aortic plaques. BACKGROUND Regression of thoracic aortic plaques by simvastatin was demonstrated using magnetic resonance imaging (MRI). However, the effects of different doses of statin have not been assessed. METHODS Using MRI, we investigated the(More)
To elucidate the effects of soybean protein and casein on postprandial lipemia, oral fat load tests were performed before and 3 weeks after the administration of soy protein isolate (SPI) and casein supplement to normolipidemic men. Eleven normolipidemic male subjects on otherwise identical controlled diets were assigned to either a 20 g/d soy protein(More)
LDL subclass pattern B, reported to have a higher prevalence in hypertriglyceridemics (HTGs), is considered to be associated with an increased risk for coronary artery disease, and the small dense LDL characteristic of this pattern is susceptible to oxidative modification. Alcohol is considered one of the most frequent causes of increases in plasma(More)
BACKGROUND Vascular endothelial growth factor (VEGF) has been implicated in both angiogenesis and ischemia. However, the relationship between plasma VEGF level and coronary artery disease remains unknown. HYPOTHESIS Plasma VEGF level may be associated with severe coronary artery disease and other cardiovascular risk factors. METHODS We examined plasma(More)
Prospective studies showed plasma high sensitivity C-reactive protein (hsCRP) levels to be a powerful predictor of cardiac events. However, the association between hsCRP levels and the extent of coronary stenosis in patients with coronary artery disease (CAD) remains controversial. We investigated the association between hsCRP levels and the extent of(More)
