One key problem in modern medical imaging is linking measured data and actual physiological quantities. In this article we derive such a link between the electrical bioimpedance of lung parenchyma, which can be measured by electrical impedance tomography (EIT), and the magnitude of regional ventilation, a key to understanding lung mechanics and developing(More)
BACKGROUND Human-activated protein C (APC) is a serine protease with anticoagulant, anti-inflammatory and cytoprotective functions. This feature renders APC to be a promising vascular-inflammatory biomarker. OBJECTIVE The aim of the present study was the development and validation of a technique that allows the measurement of APC plasma levels under(More)
Levels of C-reactive protein (CRP), uric acid (UA), and total bilirubin (TB) are associated with coronary artery disease and major adverse cardiac events (MACEs) in patients with ST-segment elevation myocardial infarction (STEMI). We retrospectively included 1167 patients with STEMI who underwent percutaneous coronary intervention and routine blood(More)
A pharmacological concentration of glucagon-like peptide-1 (GLP-1) in the insulin-deficient state clearly decreases the blood glucose level. Therefore, this study was designed to evaluate a putatively relevant effect of the gastrointestinal peptide as an adjuvant to insulin replacement therapy. GLP-1 (GLP-1(7-36) amide 10 pmol x kg(-1) x min(-1)) was(More)
To establish potential effects of glucagon-like peptide I (GLP-I) on blood glucose control in insulin-deficient states, GLP-I [GLP-I(7-36) amide; 10 pmol x kg(-1) x min(-1)] was infused intravenously in six fasting, canine C-peptide-negative, chronically diabetic dogs for 8 h. Blood samples were saved for the analysis of hormones, metabolites, and turnover(More)
INTRODUCTION Patients with acute respiratory distress syndrome (ARDS) typically show a high degree of ventilation inhomogeneity, which is associated with morbidity and unfavorable outcomes. Electrical impedance tomography (EIT) is able to detect ventilation inhomogeneity, but it is unclear which method for defining the region of interest (ROI) should be(More)
OBJECTIVE Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy (SCM) resembles a reversible cardiomyopathy that is characterized by localized wall motion abnormalities in the absence of stenotic coronary vascular disease. Patients typically present with apical ballooning of the left ventricle (LV), however the right ventricle (RV) is also(More)
BACKGROUND While coronary artery bypass grafting remains the standard treatment of complex multivessel coronary artery disease, the advent of peripheral ventricular assist devices has enhanced the safety of percutaneous coronary intervention. We therefore evaluated the safety in terms of inhospital outcome comparing protected high-risk percutaneous coronary(More)
INTRODUCTION Lung-protective ventilation aims at using low tidal volumes (VT) at optimum positive end-expiratory pressures (PEEP). Optimum PEEP should recruit atelectatic lung regions and avoid tidal recruitment and end-inspiratory overinflation. We examined the effect of VT and PEEP on ventilation distribution, regional respiratory system compliance(More)
