The prediction of impurity peaking in future fusion devices such as ITER necessitates the study of the dependence on Z of the impurity transport in present devices. In this paper we describe a novel technique to determine the transport of impurities with different atomic numbers independently. A technique has been developed that allows simultaneously the measurement of the transport of Ne and Ar i
It is plausible that polymorph isms in the estrogen receptor alpha and beta genes (ESR1 and ESR2) may modulate the association between enterolactone and breast cancer. Seven polymorph isms in ESR1 (rs827422, rs1709184, rs2347867, rs3020328, rs72207, rs2982896, and rs2234693) and 5 polymorphisms in ESR2 (rs915057, rs1269056, rs1256033, rs3020450, and rs3020443) were selected. The risk of breast can
A selective and sensitive method is presented for biogenic amines (BA) determination. The novelty consists in coupling a highly selective electrochemical biosensor to a weak acid cation-exchange column for online detection of amines. A bienzyme design, based on a recently isolated amine oxidase from grass pea and commercial horseradish peroxidase, was used for the biosensor construction. The enzym
A continuous supermacroporous monolithic chromatographic matrix has been characterized using a capillary model, experimental breakthrough curves, and pressure drop experiments. The model describes the convective flow and its dispersive mixing effects, mass transfer resistance, pore size distribution, and the adsorption behavior of the monolithic matrix. It is possible to determine an effective por
Hordeins from H. vulgare, H. murinum, H. pusillum, H. bulbosum, and H. brevisubulatum were probed with five monoclonal antibodies raised against different hordein polypeptides from Hordeum vulgare cv. ‘Bomi’. The response pattern differed widely among species. One of the antibodies, CMpBChorl, was found to react with hordein from every tested species, and all of the antibodies reacted with at leas
Genetic diversity in eight populations of Sphagnum capillfolium from different Bulgarian mountains was investigated by means of isozyme electrophoresis. High levels of allelic diversity were found (H-s = 0.119), comparable to earlier estimates for northern European populations (H-s = 0.116). Strong differentiation among populations and a low number of widespread genotypes suggest a high degree of
Allergic contact dermatitis to rubber is caused by residues of chemicals used in manufacturing a rubber product. Several different additives are used to achieve a final product of the desired characteristics. Accelerators such as thiurams, dithiocarbamates, and mercaptobenzothiazoles are often among the additives responsible for allergic reactions recognized by dermatologists. The chemistry of the
Two experiments examined the realism in the confidence of 8-9-year-olds,12-13-year-olds and adults in their free recall and answers to focused questions after viewing a short videoclip. A different videoclip was shown in each experiment and the focused questions differed in difficulty. In both experiments the youngest age group, in contrast to the two other age groups, showed no overconfidence in
Effectors of the innate immune system, the anti-bacterial peptides, have pivotal roles in preventing infection at epithelial surfaces. Here we show that proteinases of the significant human pathogens Pseudomonas aeruginosa, Enterococcus faecalis, Proteus mirabilis and Streptococcus pyogenes, degrade the antibacterial peptide LL-37. Analysis by mass spectrometry of fragments generated by P. aerugin
The first identification of a sex pheromone of a pine sawfly (Hymenoptera, Diprionidae) dates back almost thirty years. Since then, female-produced pheromones of over twenty diprionid species have been investigated by solvent extraction followed by separation and identification. However, no study has shown what the females actually release. Collection of airborne compounds using absorbtion on char
Mutations in type 3 repeats of cartilage oligomeric matrix protein (COMP) cause two skeletal dysplasias, pseudoachondroplasia (PSACH) and multiple epiphyseal dysplasia (MED). We expressed recombinant wild-type COMP that showed structural and functional properties identical to COMP isolated from cartilage. A fragment encompassing the eight type 3 repeats binds 14 calcium ions with moderate affinity
Of patients with in-hospital cardiac arrest, those with pulseless electrical activity ( PEA) have the worst outcome. Especially in these patients effective chest compressions according to the guidelines may be the key strategy to improve survival. Recently, a novel automatic mechanical chest compression device (LUCAS-CPR) has been shown to ensure effective continuous compressions without interrupt
Aims: The airways of patients with asthma are characterized by chronic inflammatory changes comprising mainly T-cells and eosinophils, and airway remodelling with goblet cell metaplasia and submucosal gland hyperplasia. Mucus hypersecretion is often a marked feature, particularly in status asthmaticus. The matrix of airway sputum consists of high molecular glycoproteins and mucins. In this study,
Bridge-splitting of trans-[PtCl2(eta(2)-CH2=CH2)](2), 1, by L in dichloromethane yields trans-[PtCl2(eta(2)-CH2=CH2)(L)] (L = THF, 2, or MeCN, 3) with bridge-splitting equilibrium constants of 0.0289 +/- 0.0007 and 3601 +/- 215 mol(-1) dm(3), respectively, as determined by UV/Vis measurements. The reaction of 3 in MeCN with Cl- is essentially quantitative. The crystal structure of trans-[PtCl2(eta
c-jun activation has been implicated not only in neuronal apoptosis, but also in survival and regeneration. This Janus facet of c-Jun activation could be related to neuronal cell type or to the developmental stage of the neuron. We investigated c-Jun activation in E18 sensory neurons. Cultures of rat dorsal root ganglia neurons were maintained with or without the addition of nerve growth factor or
