Human adipose-derived stem cells (ASCs) have the capacity to regenerate and the potential to differentiate into multiple lineages of mesenchymal cells. The aim of this study was to investigate the possibility of using honeycomb collagen scaffold to culture ASCs in bone tissue engineering. The osteogenic capacity of ASCs in vitro, was confirmed by histology(More)
Age is a well-established risk factor for cardiovascular disease. Recent trials using intravascular ultrasound (IVUS) have shown that lipid-lowering therapy with statins halts the progression or induces the regression of coronary artery plaques. However, impacts of age on coronary atherosclerosis and vascular response to statin therapy have not been fully(More)
Thin-cap fibroatheroma (TCFA) is the most common type of vulnerable plaque and is the precursor of plaque rupture. However, rupture of a TCFA is not the only mechanism underlying thrombus formation or acute coronary syndrome. Although statin therapy changes the composition of coronary artery plaques, the effects of statins, particularly different types of(More)
A low ratio of n-3 to n-6 polyunsaturated fatty acids has been associated with cardiovascular events. However, the effects of this ratio on coronary atherosclerosis have not been fully examined. The purpose of the present study was to evaluate the correlations between the n-3 to n-6 polyunsaturated fatty acid ratio and coronary atherosclerosis. Coronary(More)
BACKGROUND Systemic therapy with statin has been shown to lower the risk of coronary events; however, the in vivo effects of statin therapy on plaque volume and composition are less understood. METHODS We conducted a prospective, open-labeled, randomized, multicenter study in 11 centers in Japan. A total of 164 patients were randomized to receive either 4(More)
A low n-3 to n-6 polyunsaturated fatty acid (PUFA) ratio is associated with cardiovascular events. However, the effects of this ratio on coronary atherosclerosis have not been fully examined, particularly in patients treated with different types of statins. This study compared the effects of n-3 to n-6 PUFA ratios on coronary atherosclerosis in patients(More)
BACKGROUND Patients with diabetes mellitus (DM) have a markedly increased incidence of adverse cardiovascular events, but the mechanisms have not been well-characterized. METHODS AND RESULTS The TRUTH study evaluated the effects of 8-month statin therapy on coronary artery plaque composition using virtual histology intravascular ultrasound (IVUS).(More)
A rotation-invariant neocognitron, which has been recently proposed by authors, is trained by using handwritten numerical patterns provided by ETL-1 database. A new learning algorithm, " auto-generating algorithm " , is proposed and the learning time is reduced. The model can recognize realistic handwritten patterns. It is also shown that the model is(More)
