There is accumulating evidence that soluble amyloid-beta (Abeta) oligomers, rather than amyloid fibrils, are the principal pathogenic species in Alzheimer disease (AD). Here, we have developed a novel enzyme-linked immunosorbent assay (ELISA) specific for high-molecular-weight (HMW) Abeta oligomers. Analysis of Abeta oligomers derived from synthetic Abeta(More)
This study used matrix-assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI-TOF MS) to identify all lipid classes in human serum lipoproteins. After the major lipoproteins classes were isolated from serum by ultracentrifugation, the lipids were extracted and mixed with 2,5-dihydroxybenzoic acid (2,5-DHB) dissolved in Folch's(More)
BACKGROUND The present study was designed to test the hypothesis that fluvastatin might improve arterial stiffness, as assessed with pulse wave velocity (PWV), in patients with coronary artery disease (CAD) and hyperlipidemia over the long term. METHODS AND RESULTS Ninety-three patients were randomly assigned to either fluvastatin (group A, n=50) or(More)
Apolipoprotein (apo) J, abundant in cerebrospinal fluid (CSF), is known to play a role in the pathogenesis of Alzheimer's disease (AD); however, the mechanism remains obscure. To characterize the apoJ-containing lipoproteins in CSF, we compared the distribution of apoJ in CSF lipoprotein partides with those of apoE and apoAI. CSF lipoproteins (fractionated(More)
BACKGROUND The present study was designed to examine whether serum uric acid (SUA) levels were associated with cardiometabolic risk factors and to determine optimal cut-offs for SUA to identify multiple risk factors among Japanese junior high school students. METHODS AND RESULTS A total of 958 students (518 boys and 440 girls, aged 12.1-15.0 years) who(More)
BACKGROUND The treatment effects of rosuvastatin on arterial stiffness were assessed and compared to those of fluvastatin in high-risk Japanese patients with dyslipidemia in a primary prevention group. METHODS AND RESULTS Patients were randomly assigned to either 2.5-5 mg/day of rosuvastatin (Group A) or 20-40 mg/day of fluvastatin (Group B) and followed(More)
BACKGROUND Cysteine-bound transthyretin (TTR) in serum is believed to be associated with deposition of amyloid in familial amyloidotic polyneuropathy (FAP). We examined the binding of cysteine and homocysteine with TTR, and the effect of such binding on TTR structure. METHODS The concentration of serum cysteine and homocysteine was measured using HPLC and(More)
BACKGROUND An increase in plasma low-density lipoprotein (LDL) is a well-known risk factor in the development of atherosclerosis. Dairy consumption may lower the risk of atherosclerosis; however, studies on the effects of milk on cardiovascular risk factors are still scarce. We were interested in investigating whether the intake of milk improves the(More)
Investigation of the interactions of nerve cells with human apolipoprotein E (apoE), beta-amyloid (Abeta), and their complex, which are known to be included in senile plaques, is necessary to clarify the functional role of apoE in the pathogenesis of Alzheimer's disease. Using flow cytometric analysis, we investigated the isoform-specific effects of apoE on(More)
