INTRODUCTION Depressive disorders have been identified as independent risk factors for coronary heart disease. The present study (i) compared platelet function of depressed patients with that of healthy controls, (ii) analysed possible aggregability changes during 3 months of treatment with antidepressants, and (iii) sought to assess different effects of(More)
Chronic obstructive pulmonary disease (COPD) is a leading cause of death worldwide, with a continually rising mortality rate. As COPD is driven by abnormal pulmonary and systemic inflammation, Toll-like receptors (TLRs) seem to be important. TLRs play a key role in innate response, and in particular TLR2 gene polymorphisms Arg677Trp and Arg753Gln have been(More)
OBJECTIVE Obstructive sleep apnoea (OSA) has been implicated as a risk factor for atherosclerosis. The aim of our study was to examine the effects of chronic intermittent hypoxia in apoE-/- mice serving as model of OSA on endothelial dysfunction and oxidative stress and to evaluate the reversibility of hypoxia-induced changes under anti-inflammatory(More)
Intermittent hypoxia seems to be a major pathomechanism of obstructive sleep apnea-associated progression of atherosclerosis. The goal of the present study was to assess the influence of hypoxia on endothelial function depending on the initial stage of vasculopathy. We used 16 ApoE-/- mice were exposed to a 6-week-intermittent hypoxia either immediately(More)
STUDY OBJECTIVE The pathogenesis of chronic obstructive pulmonary disease (COPD) is characterized by an interaction of environmental influences, particularly cigarette smoking, and genetic determinants. Given the global increase in COPD, research on the genomic variants that affect susceptibility to this complex disorder is reviving. In the present study,(More)
AIMS We assessed aortic valves from patients with non-rheumatic aortic valve stenosis (AS) and with degenerative aortic valve bioprostheses (BP) for the presence of progenitor cell and leukocyte subtype-specific markers. METHODS AND RESULTS Diseased valve probes from a total of 87 patients (60 AS and 27 BP) were studied. We assessed presence and(More)
BACKGROUND Increasing evidence supports a link between serological evidence of pathogen burden (PB) and the risk for future cardiovascular events. Our study evaluates the intimal presence of 4 pathogens in atheroma, clinically associated with acute coronary syndromes (ACS) and stable angina (SA), and the effect on the expression of intimal C-reactive(More)
BACKGROUND AND AIM OF THE STUDY The presence of five pathogens was assessed, together with a possible correlation of the total pathogen burden on inflammation and (auto)immunity in aortic stenosis (AS) and degenerative aortic valve bioprosthesis (BP). METHODS Diseased valve specimens from a total of 68 patients (52 with AS, 16 with BP) were studied. The(More)
BACKGROUND Increased proliferation, mitigated apoptosis, and recruitment of primarily extravascular cells to injured vessels are important processes during neointima formation. Therefore, the goal of this study was to assess the spatiotemporal balance between proliferation and apoptosis and the influence of apoptosis on the survival of primarily(More)
STUDY OBJECTIVE The etiology of chronic obstructive lung disease (COPD) is unclear. It is supposed to be the product of an exogenous antigenic stimulus, such as tobacco smoke, and an endogenous genetic susceptibility. The angiotensin-converting enzyme (ACE) gene contains a polymorphism based on the presence (insertion [I]) or absence (deletion [D]) of a(More)
