Four patients had the clinical features of 'ampulla cardiomyopathy', consisting of acute-onset transient left ventricular apical akinesis with basal normokinesis, normal coronary angiogram, ST-segment elevation and subsequent giant T wave inversion, which mimicked acute coronary syndrome, the onset of which occurred shortly after extreme mental stress.(More)
Chondroitin sulfate dipalmitoylphosphatidylethanolamine (CS-PE), when immobilized onto substratum, inhibited the adhesion of B16F10 mouse melanoma cells to fibronectin-coated dishes (anti-adhesion activity). CS-PE showed the most potent anti-adhesion activity for the melanoma cells among various GAG-PEs. CS-PE also inhibited the adhesion of B16F10 cells to(More)
We have shown previously that chondroitin sulfate, but not heparan sulfate/heparin, linked to either natural core proteins or serum albumin interferes with cell-to-substrate adhesion, provided that the external proteoglycans are topologically immobilized on plastic plates. In order to study the roles of glycosaminoglycan chains (GAGs) as recognition(More)
The possible involvement of lecithin-cholesterol acyltransferase (LCAT) in the metabolism of oxidized phosphatidylcholine (PC) in plasma was investigated. A variety of oxidized products are formed from PC following oxidation of low density lipoproteins (LDL). A significant increase in LDL oxidation levels in patients with familial LCAT deficiency (FLD) has(More)
