INTRODUCTION Available data on fibrin clot properties and fibrinolysis in hyperthyroidism and hypothyroidism are inconsistent. Our objective was to assess the impact of effective treatment of hyper- and hypothyroidism on fibrin clot characteristics. MATERIAL AND METHODS In a case-control study, ex vivo plasma fibrin clot permeability (Ks) and efficiency(More)
Pulmonary embolectomy is a treatment option in selected patients with high-risk pulmonary embolism (PE). Efficiency of thrombus degradation in PE largely depends on the architecture of its fibrin network, however little is known about its determinants. We present the case of a 56-year-old woman with high-risk PE and proximal deep-vein thrombosis, whose(More)
Little is known about architecture of intraluminal thrombus (ILT) in abdominal aortic aneurysm (AAA). We present a 74-year-old woman with AAA and high cardiovascular risk. Scanning electron microscopy of ILT removed during surgery showed that its luminal layer is relatively rich in fibrin fibers forming irregular compact structure with low amounts of(More)
We describe a new technique for random surface texturing of a gallium nitride (GaN) light-emitting diode wafer through a mask-less dry etch process. This involves depositing a sub-monolayer film of silica nanospheres (typical diameter of 200 nm) and then subjecting the coated wafer to a dry etch process with enhanced physical bombardment. The silica spheres(More)
This paper presents the idea of convergence of the IT and telecommunication worlds, based on an example application. The program has been developed in Microsoft Visual Web Developer 2008 environment. As one of the aims the possibilities of convergence are being described. The example application allows users to communicate by video conference using soft(More)
The traditional approach to cavoatrial thrombus excision requires median sternotomy, cardiopulmonary bypass with or without hypothermia and circulatory arrest and is associated with significant morbidity and mortality. We describe a transoesophageal echocardiography guided balloon catheter assisted technique for cavoatrial thrombectomy that avoids(More)
OBJECTIVES Elevated asymmetric dimethylarginine (ADMA) is associated with an increased risk of coronary artery disease. A prognostic value of ADMA following coronary artery bypass grafting (CABG) is unknown. The aim of the current study was to assess the effect of CABG on ADMA and oxidative stress and determine their associations with postoperative(More)
Aortic stenosis (AS), the most prevalent acquired valvular disease in the adults that requires invasive treatment, coexists with coagulopathy, resulting in bleeding in approximately 20% of patients. In the current review, we summarize the available knowledge on the mechanisms underlying the bleeding tendency observed in AS, and discuss potential(More)
This article presents methodology of simple model building for risk stratification of sudden cardiac death based on an original ECG signal analysis platform. The method includes the analysis of the ECG signal, extraction of selected parameters and model optimization for predicting sudden cardiac death.
