Acute aortic dissection is a cardiovascular emergency and can quickly lead to death, therefore it requires prompt diagnosis and treatment. Exact knowledge of the true and false lumen and dissection membrane topology is vital for treatment planning. Up to now for the diagnosis of an aortic dissection multiplanar reformatting, maximum intensity projection,(More)
The majority of lung cancers (LC) belong to the non-small cell lung carcinoma (NSCLC) type. The two main NSCLC sub-types, namely adenocarcinoma (AC) and squamous cell carcinoma (SCC), respond differently to therapy. Whereas the link between cigarette smoke and lung cancer risk is well established, the relevance of non-canonical Wnt pathway up-regulation(More)
Acute aortic dissection is a life-threatening condition and must be diagnosed and treated promptly. For treatment planning the reliable identification of the true and false lumen is crucial. However, a fully automatic Computer Aided Diagnosis system capable to display the different lumens in an easily comprehensible and timely manner is still not available.(More)
The purpose of this study was to investigate Fragile X Syndrome (FXS)-related mechanisms in schizophrenia, including CGG triplet expansion, FMR1 mRNA, and fragile X mental retardation protein (FMRP) levels in lymphocytes. We investigated 36 patients with schizophrenia and 30 healthy controls using Southern blot analysis, mRNA assay, and enzyme-linked(More)
Spermatogenesis is a transitionary process in which the diploid spermatogonia transform into haploid mature spermatozoa. Actin and myosin have been implicated in various aspects during spermatogenesis. Actin is present in the form of monomer, oligomer and polymer within cells, the latter is called microfilament. There are five actin-containing structures(More)
We set out to investigate the time-dependent colon motility and inflammatory changes in a rodent model of 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis in order to estimate the efficacy of N-methyl-D-aspartate (NMDA) receptor antagonist therapy administered 6 day after the acute inflammatory event. Anaesthetized Sprague-Dawley rats were(More)
In the aging lung, the lung capacity decreases even in the absence of diseases. The progenitor cells of the distal lung, the alveolar type II cells (ATII), are essential for the repair of the gas-exchange surface. Surfactant protein production and survival of ATII cells are supported by lipofibroblasts that are peroxisome proliferator-activated receptor(More)
We discuss the physical picture of thick vortices as the mechanism responsible for confinement at arbitrarily weak coupling in SU(2) gauge theory. By introducing appropriate variables on the lattice we distinguish between thin, thick and ‘hybrid’ vortices, the latter involving Z(2) monopole loop boundaries. We present numerical lattice simulation results(More)
In the first part of the present paper, a novel communication scheme of an autonomous robot team via Bluetooth radio is investigated. In the presented solution, an autonomous unit is equipped with two independent Bluetooth radios and so a relatively fast communication is possible in the team in a static (i.e. no ad-hoc) networking topology. The performance(More)
