BACKGROUND Recent studies have reported development of neoatherosclerosis (NA) inside the stents several years after stent implantation. The aim of this study was to determine the predictors for NA using optical coherence tomography. METHODS AND RESULTS From a total of 1080 patients who underwent optical coherence tomography, we identified 179 stents in(More)
The p38 mitogen-activated protein kinase (MAPK) is activated during heart diseases that might be associated with myocardial damage and cardiac remodeling process. Diabetic cardiomyopathy is associated with increased oxidative stress and inflammation. The purpose of this study was to investigate the role of p38alpha MAPK after experimental diabetes by using(More)
The beet cyst nematode (Heterodera schachtii Schmidt) can be controlled biologically in highly infected soils of sugar beet rotations using resistant varieties of oil radish (Raphanus sativus L. ssp. oleiferus DC.) as a green crop. Resistant plants stimulate infective juveniles to invade roots, but prevent them after their penetration to complete the life(More)
Emerging evidence suggests that neointimal degenerative changes with development of neoatherosclerosis (NA) may represent an important mechanism for late stent failure. The aim of the present study was to investigate the relation between degree of neointimal hyperplasia and incidence and characteristics of NA using optical coherence tomography. We(More)
Cardiac hypertrophy is a common response to pressure overload and is associated with increased mortality. Mechanical stress in the heart can result in the integrin-mediated activation of focal adhesion kinase and the subsequent recruitment of the Grb2 adapter molecule. Grb2, in turn, can activate MAPK cascades via an interaction with the Ras guanine(More)
OBJECTIVES The aim of this study was to investigate the reliability of frequency domain optical coherence tomography (FD-OCT) for coronary measurements compared with quantitative coronary angiography (QCA) and intravascular ultrasound (IVUS). BACKGROUND Accurate luminal measurement is expected in FD-OCT because this technology offers high resolution and(More)
OBJECTIVES This study aimed to investigate the role of intraplaque neovascularisation (NV) in culprit lesions and non-culprit lesions of unstable angina pectoris (UAP) and in lesions of stable angina pectoris (SAP) using optical coherence tomography (OCT). DESIGN This study was a retrospective study. SETTING The significance of NV for culprit and(More)
Acute coronary occlusion results in ischemia-mediated death of cardiomyocytes. In the days and weeks following myocardial infarction (MI), left ventricular remodeling occurs that is characterized by persistent cardiomyocyte apoptosis, thinning and fibrosis at the site of infarction, ventricular chamber dilatation, and growth of remaining viable(More)
BACKGROUND Patients with acute coronary syndrome (ACS) have a higher incidence of recurrent ischemic events. The aim of this study was to compare the plaque characteristics of nonculprit lesions between ACS and non-ACS patients using optical coherence tomography (OCT) imaging. METHODS AND RESULTS Patients who had 3-vessel OCT imaging were selected from(More)
