OBJECTIVE: Previously, decoy receptor 3 (DcR3) was found to be a potential angiogenetic factor, while the relationship of DcR3 with coronary collateral circulation formation has not been investigated. In this study, we aimed to investigate whether plasma decoy receptor 3 levels was associated with CCC formation and evaluate its predictive power for CCC status in patients with coronary artery disease. METHODS: Among patients who underwent coronary angiography with coronary artery disease and had a stenosis of ≥90% were included in our study...

It has been suggested that hepatobiliary carcinomas are less frequent in Wilson's disease (WD) than in liver diseases of other etiology. However, the protective role of copper against malignancies is debated. Only a few cases of cholangiocarcinoma (CCC) in WD have been published. Here we report on a case of a 47-year-old male H1069Q homozygous, Kayser-Fleischer ring positive WD patient with a low ceruloplasmin level who was followed up and treated with chelating agents throughout nine years. The patient presented with neurological symptoms and liver cirrhosis at diagnosis...

Reliable models describing Pb transfer from soils to food crops are useful in the improvement of soil protection guidelines. This study provides mechanistic insights from in-situ soil solution measurement on the Pb uptake in the root tissues (RF) of radish, grown in 25 representative Pb-contaminated agricultural soils. Lead speciation and regression analysis indicate that >88.6% of the variation in RF Pb is attributable to free Pb(2+) activity (aPb(2+)) in the soil solution, which is predominantly controlled by pH and DOC...

Following endocytosis into the endosomal network, integral membrane proteins undergo sorting for lysosomal degradation or are retrieved and recycled back to the cell surface. Here we describe the discovery of an ancient and conserved multiprotein complex that orchestrates cargo retrieval and recycling and, importantly, is biochemically and functionally distinct from the established retromer pathway. We have called this complex 'retriever'; it is a heterotrimer composed of DSCR3, C16orf62 and VPS29, and bears striking similarity to retromer...

UltraLink was functionalized with a triazolium cyclodextrin click cluster (CCC) which provides a well-oriented, multivalent, positively charged binding site for PtdIns(3,4,5)P3. MALDI TOF MS and LC ESI MS/MS MRM analysis of spiked PtdIns(3,4,5)P3 in lipid extract suggest that triazolium CCC-UltraLink conjugate can be used as an enrichment material for PtdIns(3,4,5)P3.

BACKGROUND: Language problems may negatively affect children's behaviour and have detrimental effects on the development of peer-relations. AIMS: We investigated and compared emotional and behavioural profiles in children with SLI and in children with ASD aged 6-15 years and explored to what extent pragmatic language problems contributed to the emotional and behavioural needs (EBN) in these clinical groups. METHODS AND PROCEDURES: The ASD group consisted of 23 children (19 boys; 4 girls) and the SLI group consisted of 20 children (18 boys; 2 girls)...

BACKGROUND: Radiomic analyses of CT images provide prognostic information that can potentially be used for personalized treatment. However, heterogeneity of acquisition- and reconstruction protocols influences robustness of radiomic analyses. The aim of this study was to investigate the influence of different CT-scanners, slice thicknesses, exposures and gray-level discretization on radiomic feature values and their stability. MATERIAL AND METHODS: A texture phantom with ten different inserts was scanned on nine different CT-scanners with varying tube currents...

We investigated the relationship between gonadotropin-releasing hormone receptor (GnRHR) gene polymorphisms and outcome of patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization and embryo transfer (IVF-ET). PCOS patients undergoing IVF-ET were selected, and infertile patients due to dysfunctional oviducts served as controls. GnRHR gene polymorphisms were detected using the polymerase chain reaction-restriction fragment length polymorphism assay. Gene-gene interaction and linkage disequilibrium tests were performed using the SHEsis software...

We have studied how simultaneously elevated temperature and CO2 levels [climate change-related conditions (CCC) of 30°C, 970 parts-per-million (ppm) of CO2 vs. standard conditions (SC) of 25°C, ~ 405ppm CO2] affect physiochemical properties of Nicotiana benthamiana leaves, and also its infection by several positive-sense RNA viruses. In previous works we had studied effects of elevated temperature, CO2 levels separately. Under CCC, leaves of healthy plants almost doubled their area relative to SC but contained less protein/unit-of-area, similarly to what we had found under conditions of elevated CO2 alone...

Knee osteoarthritis (KOA) is the most common osteoarthritis in lower limbs, and gait measurement is important to evaluate walking function of KOA patients before and after treatment. The third generation Intelligent Device for Energy Expenditure and Activity (IDEEA3) is a portable gait analysis system to evaluate gaits. This study is to evaluate the accuracy and reliability of IDEEA3 for gait measurement of KOA patients. Meanwhile, gait differences between KOA patients and healthy subjects are examined. Twelve healthy volunteers were recruited for measurement comparison of gait cycle (GC), cadence, step length, velocity and step counts between a motion analysis system and a high-speed camera (GoPro Hero3)...

Pickering emulsions stabilized by nanoparticles have recently received great attention for their remarkable stability, in part a consequence of irreversible adsorption. In this study, we generate Pickering oil-in-water emulsions stabilized by ethyl cellulose (EC) nanoparticles without the addition of surfactants. Over a range of ionic strength and EC nanoparticle concentrations, a series of dynamic interfacial tension (IFT) measurements complemented by extended-DLVO theoretical computations are conducted to quantitatively describe the behaviour of EC nanoparticles at the interface of water with different alkanes...

Stable tissue integrity during embryonic development relies on the function of the cadherin-catenin complex (CCC). The C. elegans CCC is a useful paradigm for analyzing in vivo requirements for specific interactions among the core components of the CCC, and provides a unique opportunity to examine evolutionarily conserved mechanisms that govern the interaction between α- and β-catenin. HMP-1, unlike its mammalian homolog α-catenin, is constitutively monomeric and its binding affinity for HMP-2/βcatenin is higher than that of α-catenin for β-catenin...
