Several small case-control studies have investigated whether factor V Leiden (FVL) is a risk factor for retinal vein occlusion (RVO) and generated conflicting data. To clarify this question we performed a large two-centre case-control study and a meta-analysis of published studies. Two hundred seven consecutive patients with RVO and a control group of 150(More)
INTRODUCTION The issues related to aspirin [acetylsalicylic acid (ASA)] resistance are still under debate. Depending on the method of assessment and studied patients, the prevalence of ASA resistance is rather heterogeneous, ranging from 5% to 45%. The method most commonly used for assessing platelet function is their aggregation. ASA irreversibly inhibits(More)

OBJECTIVE The role of thrombophilia in the etiology of retinal vein occlusion (rVO) has not been adequately clarified. The aim of this study was to examine the prevalence of thrombophilia among RVO patients with and without systemic risk factors and among patients younger and older than 50 years. DESIGN Prospective case-control study. PARTICIPANTS One(More)
Kinetic properties of novel amine oxidases isolated from a mold Aspergillus niger AKU 3302 were compared to those of typical plant amine oxidase from pea seedling (EC 1.4.3.6). Pea amine oxidase showed highest affinity with diamines, such as putrescine and cadaverine, while fungal enzymes oxidized preferably n-hexylamine and tyramine. All enzymes were(More)
OBJECTIVE To assess and compare the frequency of selected gene mutations of thrombophilic markers (FV Leiden, FII prothrombin G20210A and MTHFR C677T) in patients with primary and secondary infertility. DESIGN Retrospective study. SETTING Institute of normal anatomy, Faculty of Medicine and Dentistry, Palacky University Olomouc. METHODS The study(More)
Aims: To determine the systemic thrombogenic effect of radiofrequency catheter isolation of the pulmonary veins (PVI) in the treatment of atrial fibrillation. Methods and Results: We studied endothelial damage marker (von Willebrand factor [vWf]), fibrinolysis markers (tissue plasminogen activator [t-PA], plasminogen activator inhibitor-1 [PAI-1]) and(More)
OBJECTIVE There is a growing view that inherited or acquired thrombophilia may predispose a woman towards an adverse pregnancy outcome. The aim of this study was to investigate whether risk factors for placental abruption because of such thrombophilias (such as carriership of factor V Leiden (FVL), prothrombin G20210A gene mutation and homozygous MTHFR(More)
INTRODUCTION The aim of this study was to evaluate the plasma levels of endothelial haemostatic markers - von Willebrand factor (vWF), plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen activator (t-PA) and soluble thrombomodulin (sTM) - in asymptomatic, nonsmoking members of families with familial combined hyperlipidemia (FCH). We investigated(More)
METHODS The studied group comprises 124 patients with acute myocardial infarction on dual antiplatelet therapy with acetylsalicylic acid (ASA) and thienopyridines. Antiplatelet therapy was monitored by platelet-rich plasma light transmittance aggregometry (LTA) using the APACT 4004 analyzer (Helena Laboratories) and by whole blood impedance aggregometry(More)
