A specific, highly enriching and "green" method for hollow fiber liquid phase microextraction of ionizable pharmaceuticals from fish tissue

Ionizable pharmaceuticals are a class of emerging contaminants that pose a challenge to analytical chemistry due to their low environmental concentrations. To measure such low concentrations in organism tissue, e.g. fish muscle, specific extraction techniques minimizing co-extraction and interference alongside providing high enrichment of the compounds are needed. In this study we present a techni

Rhetorical Meta-language to Promote the Development of Students’ Writing Skills and Subject Matter Understanding

Background: Feedback is one of the most significant factors for students’ development of writing skills. For feedback to be successful, however, students and teachers need a common language – a meta-language – for discussing texts. Not least because in science education such a meta-language might contribute to improve writing training and feedback-giving. Purpose: The aim of this study was to exp

Monitoring of dabigatran anticoagulation and its reversal in vitro by thrombelastography.

Dabigatran etexilate, a pro-drug of a direct thrombin inhibitor, was approved a few years ago for non-valvular atrial fibrillation and deep venous thrombosis. Rapid monitoring of the dabigatran level is essential in trauma and bleeding patients but the traditional plasma-based assays may not sufficiently display the effect. Furthermore, no antidote exists and reversal of the anticoagulant effect i

A comparison of outcomes and dislocation rates using dual articulation cups and THA for intracapsular femoral neck fractures

Total hip arthroplasty for intracapsular femoral neck fractures (FNF) is associated with a greater risk of dislocation. Dual articulation systems in this group of patients may provide better implant stability and a reduced dislocation rate. The aim of our study was to investigate FNF patients treated with dual articulation cups (DAC) and conventional THA and compare their clinical results at four

First molecular identification of Babesia gibsoni in dogs from Slovakia, central Europe.

Canine babesiosis is a severe and potentially life threatening infection. In Europe, Babesia canis is considered to be the most common species responsible for the disease. We report two cases of babesiosis caused by Babesia gibsoni. The polymerase chain reaction, restriction fragment length polymorphism analysis and further sequencing of 18S rRNA gene fragments from blood samples of both dogs reve

Devising a best practice approach to prophylaxis in boys with severe haemophilia: evaluation of current treatment strategies

Data from prospective studies clearly demonstrate the efficacy of prophylactic treatment of haemophilia in reducing joint- or life-threatening bleeding and the associated consequences for quality of life. Debate remains, however, regarding the optimal implementation of prophylaxis. Our aim in this review was to identify a best practice approach to factor replacement prophylaxis in boys with haemop

Circulating CD1c(+) DCs are superior at activating Th2 responses upon Phl p stimulation compared with basophils and pDCs.

The contributing role of circulating human dendritic cell (DC) populations and basophils in the presentation and augmentation of Th2 responses remains to be determined. The present study aimed at elucidating the functional role of CD1c(+) myeloid DCs (mDCs), CD123(+) plasmacytoid DCs (pDCs), monocyte-derived DCs and basophils in allergen presentation and Th2 activation. By coculturing Phleum prate

The Phylogenetic Distribution and Evolution of Enzymes Within the Thymidine Kinase 2-like Gene Family in Metazoa

Deoxyribonucleoside kinases (dNKs) carry out the rate-determining step in the nucleoside salvage pathway within all domains of life where the pathway is present, and, hence, are an indication on whether or not a species/genus retains the ability to salvage deoxyribonucleosides. Here, a phylogenetic tree is constructed for the thymidine kinase 2-like dNK gene family in metazoa. Each enzyme class (d

Ecology: Save the Baltic Sea.

Abstract in Undetermined Comment: Geoengineering efforts to bring oxygen into the deep Baltic should be abandoned, says Daniel J. Conley

CO2 surface fluxes at grid point scale estimated from a global 21 year reanalysis of atmospheric measurements

This paper documents a global Bayesian variational inversion of CO2 surface fluxes during the period 1988-2008. Weekly fluxes are estimated on a 3.75 degrees x 2.5 degrees (longitude-latitude) grid throughout the 21 years. The assimilated observations include 128 station records from three large data sets of surface CO2 mixing ratio measurements. A Monte Carlo approach rigorously quantifies the th

Unraveling the nature of coherent beatings in chlorosomes.

Coherent two-dimensional (2D) spectroscopy at 80 K was used to study chlorosomes isolated from green sulfur bacterium Chlorobaculum tepidum. Two distinct processes in the evolution of the 2D spectrum are observed. The first being exciton diffusion, seen in the change of the spectral shape occurring on a 100-fs timescale, and the second being vibrational coherences, realized through coherent beatin

Risk of irritable bowel syndrome in first-degree, second-degree and thirddegree relatives of affected individuals: a nationwide family study in Sweden.

IBS aggregates in families, but the familial risk of IBS has only been determined in first-degree relatives and spouses. This nationwide study aimed to determine the familial risk of IBS in first-degree, second-degree, and third-degree relatives and spouses of affected individuals in order to estimate the relative influences of genes and shared family environment.

Imaging Islamic Identity: Negotiated Norms of Representation in Euro-Muslim Picture Books

The article analyzes the recent genre of Islamic children’s picture books, originally produced as a means of religious socialization for the British Muslim communities, but marked on a global Islamic market. Particular attention is devoted to the visual norms of the books produced by one of the pioneering publishers of Islamic children’s literature, the Islamic Foundation. With one foot in the ped

MOLCAS-a software for multiconfigurational quantum chemistry calculations

At variance, with most of the quantum chemistry software presently available, MOLCAS is a package that is specialized in multiconfigurational wave function theory (MC-WFT) rather than density functional theory (DFT). Given the much higher algorithmic complexity of MC-WFT versus DFT, an extraordinary effort needs to be made from the programming point of view to achieve state-of-the-art performance

Search for New Phenomena in t(t)overbar Events with Large Missing Transverse Momentum in Proton-Proton Collisions at root s=7 TeV with the ATLAS Detector

A search for new phenomena in t (t) over bar events with large missing transverse momentum in proton-proton collisions at a center-of-mass energy of 7 TeV is presented. The measurement is based on 1: 04 fb(-1) of data collected with the ATLAS detector at the LHC. Contributions to this final state may arise from a number of standard model extensions. The results are interpreted in terms of a model

Therapeutic work with the present moment: A comparative conversation analysis of existential and cognitive therapies

Therapeutic work with the client’s present moment experience in existential therapy was studied by means of conversation analysis. Using publicly available video recordings of therapy sessions as data, an existential therapist’s practice of guiding a client into immediacy, or refocusing the talk on a client’s immediate experience, was described and compared with a therapist’s corresponding action

Influence of laser irradiated spot size on energetic electron injection and proton acceleration in foil targets

The influence of irradiated spot size on laser energy coupling to electrons, and subsequently to protons, in the interaction of intense laser pulses with foil targets is investigated experimentally. Proton acceleration is characterized for laser intensities ranging from 2 x 10(18) - 6 x 10(20) W/cm(2), by (1) variation of the laser energy for a fixed irradiated spot size, and (2) by variation of t

Asymptotic Integration Of Second-Order Nonlinear Difference Equations

In this work we analyse a nonlinear, second-order difference equation on an unbounded interval. We present new conditions under which the problem admits a unique solution that is of a particular linear asymptotic form. The results concern the general behaviour of solutions to the initial-value problem, as well as solutions with a given asymptote. Our methods involve establishing suitable complete

Performance of the ATLAS detector using first collision data

More than half a million minimum-bias events of LHC collision data were collected by the ATLAS experiment in December 2009 at centre-of-mass energies of 0.9 TeV and 2.36 TeV. This paper reports on studies of the initial performance of the ATLAS detector from these data. Comparisons between data and Monte Carlo predictions are shown for distributions of several track- and calorimeter-based quantiti
