OBJECTIVES The purpose of this study was to examine whether echolucent carotid plaques predict future coronary events in patients with clinically stable coronary artery disease (CAD). BACKGROUND Although rupture of coronary plaques is considered a major cause of acute coronary syndromes (ACS), the clinical estimation of coronary vulnerability still remains inconclusive. Ultrasound evaluation ...
OBJECTIVES The study aimed to evaluate the risk of pleural plaques according to the degree of past exposure to asbestos, type of amphibole asbestos, and smoking, as well as to estimate the aetiologic fraction of asbestos as a cause of plaques among urban men. METHODS The occurrence and extent of pleural plaques were recorded at necropsies of 288 urban men aged 33 to 69 years. The pulmonary co...
OBJECTIVES This study was carried out to detect vulnerable coronary plaques by color fluorescent angioscopy. BACKGROUND Collagen fibers (CFs) mainly provide mechanical support to coronary plaques. Oxidized low-density lipoprotein (Ox-LDL) induces macrophage proliferation, which in turn destroy CFs while accumulating lipids. As such, demonstration of the absence of CFs, deposition of lipids, a...
OBJECTIVES We investigated the relationship between ultrasonographic features of the carotid artery and the angiographic features of coronary plaques in acute coronary syndrome (ACS). BACKGROUND The carotid intima-media thickness (IMT) may be a marker of advanced coronary artery disease. METHODS Consecutive ACS patients (N = 125) underwent B-mode ultrasonography within one week of the acute...
BACKGROUND AND OBJECTIVES Chronic kidney disease (CKD) is a risk factor of cardiovascular disease. The number of yellow plaques is a predictor of future cardiovascular events. We assumed that CKD might raise the risk of cardiovascular events by increasing the number of yellow plaques. Therefore, we compared the number of yellow plaques between patients with and without CKD. DESIGN, SETTING, P...
Postmortem analyses of senile plaques reveal numerous dystrophic processes in their vicinity. We used in vivo multiphoton microscopy of a transgenic model of Alzheimer disease (AD) to simultaneously image senile plaques and nearby neuronal processes. Plaques were labeled by immunofluorescent staining or thioflavine-S and neuronal processes were labeled with a fluorescent dextran conjugate. Imag...
