Thrombin is a serine protease that potently activates platelets and catalyzes the conversion of fibrinogen to fibrin. Thrombin also exerts direct effects on vascular cells, such as smooth muscle cells, via interactions with members of the protease-activated receptor family. Evidence in several animal models implicates thrombin-mediated signaling events in(More)
AIM High-density lipoproteins (HDLs) have several potentially protective vascular effects. Most clinical studies of therapies targeting HDL have failed to show benefits vs. placebo. OBJECTIVE To investigate the effects of an HDL-mimetic agent on atherosclerosis by intravascular ultrasonography (IVUS) and quantitative coronary angiography (QCA). DESIGN(More)
BACKGROUND Strong epidemiologic evidence correlates tobacco use with a variety of serious adverse health effects, but the biological mechanisms that produce these effects remain elusive. RESULTS We analyzed gene transcription data to identify expression spectra related to tobacco use in circulating leukocytes of 67 Caucasian male subjects. Levels of(More)
BACKGROUND Individuals of African descent in the United States suffer disproportionately from diseases with a metabolic etiology (obesity, metabolic syndrome, and diabetes), and from the pathological consequences of these disorders (hypertension and cardiovascular disease). METHODOLOGY/PRINCIPAL FINDINGS Using a combination of genetic/genomic and(More)
BACKGROUND Major advances have been made in the treatment of ST-elevation myocardial infarction (STEMI) in outpatients. In contrast, little is known about outcomes in STEMI that occur in patients hospitalized for a noncardiac condition. METHODS AND RESULTS This was a retrospective, single-center study of inpatient STEMIs from January 1, 2007, to July 31,(More)
BACKGROUND Chronic unilateral renal artery stenosis (RAS) causes accelerated atherosclerosis in apolipoprotein E-deficient (ApoE(-/-)) mice, but effects of restoration of renal blood flow on aortic atherosclerosis are unknown. METHODS AND RESULTS Male ApoE(-/-) mice underwent sham surgery (n=16) or had partial ligation of the right renal artery (n=41)(More)
BACKGROUND The use of abciximab (c7E3 Fab) or eptifibatide improves clinical outcomes in diabetics undergoing percutaneous coronary intervention. These beta3 integrin inhibitors antagonize fibrinogen binding to alphaIIbbeta3 integrins on platelets and ligand binding to alphavbeta3 integrins on vascular cells. alphavbeta3 integrins influence responses to(More)
