Prenatal diagnosis of haemophilia in Sweden now more commonly used for psychological preparation than termination of pregnancy.

The aims of the study were to define the frequency, outcome and reasons for prenatal diagnosis (PND) in Sweden during a 30-year period in order to study trends and changes. The study population, from the Swedish nationwide registry of PND of haemophilia, consisted of 54 women, compromising >95% of all, who underwent PND (n = 90) of haemophilia during 1977-2013. PND was performed by amniocentesis (

Tapasin Facilitation of Natural HLA-A and -B Allomorphs Is Strongly Influenced by Peptide Length, Depends on Stability, and Separates Closely Related Allomorphs.

Despite an abundance of peptides inside a cell, only a small fraction is ultimately presented by HLA-I on the cell surface. The presented peptides have HLA-I allomorph-specific motifs and are restricted in length. So far, detailed length studies have been limited to few allomorphs. Peptide-HLA-I (pHLA-I) complexes of different allomorphs are qualitatively and quantitatively influenced by tapasin t

A method for climate and vegetation reconstruction through the inversion of a dynamic vegetation model

Climate reconstructions from data sensitive to past climates provide estimates of what these climates were like. Comparing these reconstructions with simulations from climate models allows to validate the models used for future climate prediction. It has been shown that for fossil pollen data, gaining estimates by inverting a vegetation model allows inclusion of past changes in carbon dioxide valu

A Supply Chain Perspective on Green Packaging Development -Theory Versus Practice

The purpose of this paper is to provide insight into how companies work during packaging development to reduce negative environmental impact along supply chains, and to compare their practical approaches with the theoretical concepts presented in the literature. The research approach is explorative and based on nine cases in the food and manufacturing industries in Sweden. Data were collected from

Continuous stand-alone controllable aerosol/cloud droplet dryer for atmospheric sampling

We describe a general-purpose dryer designed for continuous sampling of atmospheric aerosol, where a specified relative humidity (RH) of the sample flow (lower than the atmospheric humidity) is required. It is often prescribed to measure the properties of dried aerosol, for instance for monitoring networks. The specific purpose of our dryer is to dry cloud droplets (maximum diameter approximately

Knowledge creation and application in technology collaboration portfolio Two cases in China

Purpose - This study aims at developing a better understanding of the different mechanisms that affect technology collaboration portfolio management. How do firms manage their technology collaboration portfolio? Despite some thoughtful scholars have advanced the understanding of the phenomenon of technology collaboration portfolio, there is not much research that has been done in terms of understa

Hard fact or illusion? An investigation on momentum in female elite handball from a team perspective

Athletes constantly report experiences of momentum during athletic contests, and they consider momentum as being an important factor for the outcome of a competition. However, researchers trying to capture momentum with quantitative methods see themselves confronted with inconclusive results. To explain this gap between athletes’ belief and results from quantitative data, it is hypothesised that m

Musical marginalization processes: Problematizing the marginalization concept through an example from early 20th century American popular culture.

The author sets out to analyse a number of representations of the biblical Hagar figure in African American and white American culture. Spivak (1988) has problematized the marginalization concept with regard to the study of the third world subject, arguing that knowledge always expresses the interests of the knowledge producers, and that Western academic research is always colonial. The aim of the

Fluorescence diagnostics and kinetic studies in the head and neck region utilizing low-dose delta-aminolevulinic acid sensitization

Diagnostic measurements and pharmacokinetic studies were performed in 17 patients with various kinds of malignant, premalignant and benign lesions in the head and neck region by means of point monitoring laser-induced fluorescence. For marking different types of tissue, delta-aminolevulinic acid (ALA)-induced protoporphyrin IX (PpIX) was used. The ALA-induced PpIX synthesis was monitored at differ

Detecting speculations, contrasts and conditionals in consumer reviews

A support vector classifier was compared to a lexicon-based approach for the task of detecting the stance categories speculation, contrast and conditional in English consumer reviews. Around 3,000 training instances were required to achieve a stable performance of an F-score of 90 for speculation. This outperformed the lexicon-based approach, for which an Fscore of just above 80 was achieved. The

Search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in root s=8 TeV pp collisions with the ATLAS detector

The results of a search for top squark (stop) pair production in final states with one isolated lepton, jets, and missing transverse momentum are reported. The analysis is performed with proton-proton collision data at root s = 8 TeV collected with the ATLAS detector at the LHC in 2012 corresponding to an integrated luminosity of 20 fb(-1). The lightest supersymmetric particle (LSP) is taken to be

Pre-PCR processing in bioterrorism preparedness: improved diagnostic capabilities for laboratory response networks.

Diagnostic DNA analysis using polymerase chain reaction (PCR) has become a valuable tool for rapid detection of biothreat agents. However, analysis is often challenging because of the limited size, quality, and purity of the biological target. Pre-PCR processing is an integrated concept in which the issues of analytical limit of detection and simplicity for automation are addressed in all steps le

Trends in CO2 exchange in a high Arctic tundra heath, 2000-2010

We have measured the land-atmosphere CO2 exchange using the eddy covariance technique in a high Arctic tundra heath in northeast Greenland (Zackenberg). On the basis of 11 years of measurements (2000-2010), it was found that snow cover dynamics was important for the CO2 exchange. The start of CO2 uptake period correlated significantly with timing of snowmelt. Furthermore, for years with deep and l

Key factors determining the efficacy of gene therapy for continuous DOPA delivery in the Parkinsonian brain

L-DOPA is currently the standard treatment for alleviating the motor symptoms in Parkinson's disease. The therapeutic efficacy, however, diminishes as the disease progresses. It has been suggested that the beneficial effect of L-DOPA could be reestablished by changing the mode of administration. Indeed, continuous delivery of L-DOPA has been shown to be an effective way to circumvent many of the s

Shrunken Pore Syndrome is associated with a sharp rise in mortality in patients undergoing elective coronary artery bypass grafting.

Shrunken Pore Syndrome was recently suggested for the pathophysiologic state in patients characterized by an estimation of their glomerular filtration rate (GFR) based upon cystatin C, which is lower or equal to 60% of their estimated GFR based upon creatinine, i.e. when eGFRcystatin C ≤ 60% of eGFRcreatinine. Not only the cystatin C level, but also the levels of other low molecular mass proteins

Sampling frequency affects the processing of ActiGraph raw acceleration data to activity counts.

ActiGraph acceleration data are processed through several steps (including bandpass filtering to attenuate unwanted signal frequencies) to generate the activity counts commonly used in physical activity research. We performed three experiments to investigate the effect of sampling frequency on the generation of activity counts. Ideal acceleration signals were produced in the MATLAB software. There

Does an active sun exposure habit lower the risk of venous thrombotic events? A D-lightful hypothesis

Background: Venous and arterial thrombotic complications exhibit a seasonal variation, with risk peaking in winter and dropping to a nadir in summer. We sought a possible correlation between sun exposure habits and venous thromboembolism (VTE) events. Methods: This was a cohort study comprising 40 000 women (1000 per year of age from 25 to 64 years) who were drawn from the southern Swedish populat
