Plaque rupture and subsequent embolism as well as thrombosis are major causes of acute myocardial infarction and stroke secondary to atherosclerosis. Pai-1, t-PA, TF and ET-1 are thrombosis- and thrombolysis-related factors which play important roles in thrombosis formation and plaque rupture. Since acute myocardial infarction and stroke are more likely to occur between 6 a.m. and 12 p.m. than ...
in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...
BACKGROUND Plasminogen activator inhibitor-1 (PAI-1), the specific, fast-acting inhibitor of tissue-type plasminogen activator (t-PA), binds to fibrin and has been found in high concentrations within arterial thrombi. These findings suggest that the localization of PAI-1 to a thrombus protects that same thrombus from fibrinolysis. In this study, clot-bound PAI-1 was assessed for its ability to ...
The plasminogen (Plg)/plasminogen activator (PA) system plays a key role in cancer progression, presumably via mediating extracellular matrix degradation and tumor cell migration. Consequently, urokinase-type PA (uPA)/plasmin antagonists are currently being developed for suppression of tumor growth and angiogenesis. Paradoxically, however, high levels of PA inhibitor 1 (PAI-1) are predictive of...
The plasminogen-plasmin system has been found to modulate neoplastic spread and angiogenesis in tumors outside the central nervous system (CNS), but there have been no quantitative studies on the invasive and vascular tumors of the CNS. Quantitative zymography and enzyme-linked immunosorbent assay were used to determine the amounts of urokinase-type plasminogen activator (u-PA), tissue-type pla...
BACKGROUND/AIMS Viral infections are a major problem worldwide and many of them are complicated by virally induced glomerulonephritides. Progression of kidney disease to renal failure is mainly attributed to the development of renal fibrosis characterized by the accumulation of extracellular matrix components in the mesangial cell compartment and the glomerular basement membrane. Plasminogen ac...

Photoacoustic imaging (PA imaging or PAI) has shown great promise in the detection and monitoring of cancer. Although nanocarrier-based contrast agents have been studied for use in PAI, small molecule contrast agents are required due to their ease of preparation, costeffectiveness, and low toxicity. Here, we evaluated the usefulness of a novel cyanine dye IC7-1-Bu as a PAI contrast agent withou...
Evidence suggests that hepatocyte growth factor (HGF) ameliorates renal fibrosis in animal models of chronic renal disease by promoting extracellular matrix catabolism. This study examined the molecular mechanisms of HGF-induced alterations in matrix degradation both in vitro and in vivo. In vitro, HGF increased the collagen catabolizing activity of human proximal tubular epithelial cells (HKC)...
To assess the effects of pharmacological interruption of the renin-angiotensin system on the fibrinolysis, tissue plasminogen activator antigen (t-PA), plasminogen activator inhibitor-1 antigens (PAI-1) and neurohormones, such as plasma renin activity, norepinephrine, angiotensin II (AII) and IV (AIV) concentrations, were measured in 60 hypertensives. Among them, 48 patients were divided into t...
