RATIONALE Myocardial infarction (MI) is a leading cause of death worldwide. Because endogenous cardiac repair mechanisms are not sufficient for meaningful tissue regeneration, MI results in loss of cardiac tissue and detrimental remodeling events. MicroRNAs (miRNAs) are small, noncoding RNAs that regulate gene expression in a sequence dependent manner. Our(More)
BACKGROUND Diastolic dysfunction in response to hypertrophy is a major clinical syndrome with few therapeutic options. MicroRNAs act as negative regulators of gene expression by inhibiting translation or promoting degradation of target mRNAs. Previously, we reported that genetic deletion of the cardiac-specific miR-208a prevents pathological cardiac(More)
AIMS Recent studies have shown that microRNAs (miRNAs), besides being potent regulators of gene expression, can additionally serve as circulating biomarkers of disease. The aim of this study is to determine if plasma miRNAs can be used as indicators of disease progression or therapeutic efficacy in hypertension-induced heart disease. METHODS AND RESULTS(More)
We wished to determine, using a novel specific antagonist of BK2, HOE 140, (a) if the angiotensin-converting enzyme (ACE) inhibitor, ramiprilat, reduces myocardial infarct size in a well-established animal model of ischemia/reperfusion with minimal coronary collateralization, and (b) if the reduction in myocardial infarct size occurred through a(More)
The angiotensin-converting enzyme inhibitor ramiprilat, the angiotensin II receptor antagonist losartan, angiotensin II, ramiprilat plus angiotensin II, or saline (N = 6 each group), were administered i.v. in anesthetized, open-chest rabbit preparations of acute myocardial ischemia. Animals were instrumented for measurement of systemic hemodynamics and left(More)
The objective of this investigation was to validate a transit-time ultrasound blood flow metering system in vivo. Implanted chronically and acutely on the ascending aorta of the dog, the transit-time flow probe determined varying flow rates simultaneously with measurements made by the electromagnetic flow metering method. The transit-time technique was also(More)
Leukotrienes and histamine are thought to play important roles in the development of dermatitis. This study evaluated the in vivo efficacy of 5-{4-[(aminocarbonyl)(hydroxy)amino]but-1-ynyl}-2-(2-{4-[(R)-(4-chlorophenyl)(phenyl)methyl]piperazin-1-yl}ethoxy)benzamide (ucb 35440), a dual function histamine H1 receptor antagonist/5-lipoxygenase enzyme(More)
The objective of this investigation was to determine the role of nitric oxide synthase in the action of the angiotensin-converting enzyme inhibitor, ramiprilat, to reduce myocardial ischemia/reperfusion injury. Ramiprilat, the nitric oxide synthase inhibitor NG-nitro-L-NAME (L-NAME), ramiprilat plus L-NAME, or saline (n = 8 each group), were administered(More)
OBJECTIVE Restenosis is a common problem which limits the effectiveness of percutaneous transluminal coronary angioplasty (PTCA). The cellular mechanisms of restenosis appear to involve smooth muscle cell (SMC) migration to the neointima in response to mitogens and growth factors, resulting in proliferation and deposition of cells in the lumen of the(More)
