BACKGROUND Several studies have demonstrated that uremic patients who have preserved left ventricular ejection fraction (LVEF) could still have the potential for systolic dysfunction. The aim of this study was to assess the differences between the left ventricular (LV) myocardial function in hemodialysis and nondialysis uremic patients based on(More)
Mucin overproduction is a hallmark of nontypeable Haemophilus influenzae (NTHi) infections. The molecular mechanisms underlying up-regulation of mucin in NTHi infections especially during the initial phase remain unknown. Here we show that P6, a 16-kDa outer membrane lipoprotein well conserved in NTHi, up-regulates MUC5AC mucin gene transcription in vitro(More)
Replication protein A (RPA), the major single-stranded DNA-binding protein in eukaryotic cells, is required for processing of single-stranded DNA (ssDNA) intermediates found in replication, repair, and recombination. Recent studies have shown that RPA binding to ssDNA is highly dynamic and that more than high-affinity binding is needed for function.(More)
The polysialic acid (PSA) production in Escherichia coli (E. coli) K1 was studied using three different cultivation strategies. A batch cultivation, a fed-batch cultivation at a constant specific growth rate of 0.25 h(-1) and a fed-batch cultivation at a constant glucose concentration of 50 mg l(-1) was performed. PSA formation kinetics under different(More)
Vibrio parahaemolyticus is an important halophilous pathogen that can cause not only a broad range of disease in aquatic animals but also serious seafood-borne illness in humans as a result of the consumption of seafood. To avoid the use of antibiotics, it is critical to identify protective antigens for developing highly effective vaccines against this(More)
With the advancement of nanotoxicology and nanomedicine, it has been realized that nanoparticles (NPs) interact readily with biomolecular species and other chemical and organic matter to result in biocorona formation. The field of the environmental health and safety of nanotechnology, or NanoEHS, is currently lacking significant molecular-resolution data,(More)
Aflatoxins are a group of secondary metabolites produced by Aspergillus flavus and Aspergillus parasiticus with carcinogenicity, teratogenicity, and mutagenicity. Aflatoxins may be found in a wide range of agri-products, especially in grains, oilseeds, corns, and peanuts. In this study, the conditions for detoxifying peanuts by ozonation were optimised.(More)
Regression testing which is part of the software life cycle costs much time in the whole process of testing, especially in GUI (Graphical User Interface) testing. Thus aiming at the object-oriented software, we propose a method called function-diagram based regression testing. GUI is described by function-diagram; regression testing cases are selected by(More)
Ixodid ticks are well known for spreading transmitted tick-borne pathogens while being attached to their hosts for almost 1-2 weeks to obtain blood meals. Thus, they must secrete many immunosuppressant factors to combat the hosts' immune system. In the present work, we investigated an immunosuppressant peptide of the hard tick Amblyomma variegatum. This(More)
