Interlead variability of the QT interval in surface electrocardiogram (ECG), i.e., QT dispersion, reflects regional differences in ventricular recovery time, and it has been linked to the occurrence of malignant arrhythmias in different cardiac diseases. The purpose of the study was to assess the effect of hemodialysis on QT and corrected QT (QTc) interval(More)
In addition to their cytotoxic nature, reactive oxygen species (ROS) are also signal molecules in diverse cellular processes in eukaryotic organisms. Linking genome-wide transcriptional changes to cellular physiology in oxidative stress-exposed Aspergillus nidulans cultures provides the opportunity to estimate the sizes of peroxide (O22-), superoxide (O2•-)(More)
BACKGROUND Diplopia identifies patients with eye muscle involvement in Graves' ophthalmopathy (GO). OBJECTIVE To identify clinical parameters that could eliminate the need for magnetic resonance imaging (MRI) to assess the activity of inflammation in the eye muscles of GO patients with diplopia. METHODS In 43 patients with GO with recently developed(More)
Carbon starvation is a common stress for micro-organisms both in nature and in industry. The carbon starvation stress response (CSSR) involves the regulation of several important processes including programmed cell death and reproduction of fungi, secondary metabolite production and extracellular hydrolase formation. To gain insight into the physiological(More)
Under long-term oxidative stress caused by menadione sodium bisulfite, genome-wide transcriptional and proteome-wide translational changes were compared in Aspergillus nidulans vegetative cells. The comparison of proteomic and DNA microarray expression data demonstrated that global gene expression changes recorded with either flip-flop or dendrimer cDNA(More)
Stress-response proteins of Aspergillus nidulans, Aspergillus clavatus, Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Aspergillus oryzae, Aspergillus terreus and Neosartorya fischeri (3908 in total) were annotated and grouped according to stress types (http://193.6.155.82/AspergillusStress/). All genomes harboured elements of the(More)
BACKGROUND The presence of anti-cyclic citrullinated peptide autoantibody is highly specific for rheumatoid arthritis. Certain HLA-DR4 (HLA-DRB1*04) alleles, also known as the "shared epitope," are associated with increased susceptibility to RA. In addition, these alleles may also have relevance for disease outcome. Anti-CCP antibody positivity has been(More)
OBJECTIVE To assess the iodine nutritional status and the prevalence of goitre during pregnancy in a region of Hungary that appeared to be iodine sufficient in previous studies. DESIGN A cross-sectional voluntary screening study was organized in which 313 pregnant women participated. METHODS Urine iodine concentration and the volume of the thyroid gland(More)
UNLABELLED Correlation of the plasma levels of insulin-sensitizing, anti-inflammatory and anti-atherosclerotic adiponectin with HDL has been demonstrated. However, its relation to HDL-bound paraoxonase 1 (PON1) has not been clarified. The association of serum PON1 activity with findings of metabolic syndrome was investigated in three age and sex-matched(More)
The pseudotrisaccharide allosamidin, a potent inhibitor of chitinases, retarded the fragmentation of hyphae but did not affect the fungal growth and cephalosporin-C production in Acremonium chrysogenum. In vitro inhibition of A. chrysogenum cell-bound chitinase(s) by allosamidin revealed that about 47% of the soluble intracellular chitinase activity was(More)
