A haplotype in the inducible T-cell tyrosine kinase is a risk factor for seasonal allergic rhinitis

Background: Identification of disease-associated single nucleotide polymorphisms (SNPs) in seasonal allergic rhinitis (SAR) may be facilitated by focusing on genes in a disease-associated pathway. Objective: To search for SNPs in genes that belong to the T-cell receptor (TCR) pathway and that change in expression in allergen-challenged CD4+ cells from patients with SAR. Methods: CD4+ cells from pa

The Healthcare Voucher: Emergence, Formation and Dissemination

Market-inspired healthcare reforms have been introduced in Sweden: Freedom of Choice in Healthcare in 1989 and the National Healthcare Guarantee in 2005. After the general election 2006 the idea of the Healthcare Voucher has followed. Built on a theoretical framework composed of Foucault's concept of 'discursive formation' supported by Butler's concept of the ‘performativity of discourse’ the purp

A Short Period of Ventilation without Perfusion Seems to Reduce Atelectasis without Harming the Lungs during Ex Vivo Lung Perfusion.

To evaluate the lung function of donors after circulatory deaths (DCDs), ex vivo lung perfusion (EVLP) has been shown to be a valuable method. We present modified EVLP where lung atelectasis is removed, while the lung perfusion is temporarily shut down. Twelve pigs were randomized into two groups: modified EVLP and conventional EVLP. When the lungs had reached 37°C in the EVLP circuit, lung perfus

Influence of bark on fuel ethanol production from steam-pretreated spruce.

Bark and bark-containing forest residues have the potential for utilization as raw material for lignocellulosic ethanol production due to their abundance and low cost. However, the different physical properties and chemical composition of bark compared to the conventionally used wood chips may influence the spruce-to-ethanol bioconversion process. This study assesses the impact of bark on the over

System analysis of a PV/T hybrid solar window

A building-integrated multifunctional PV/T solar window was suggested and developed by Andreas Fieber. The solar window is constructed of PV cells laminated on solar absorbers placed in a window behind the glazing. To reduce the costs of solar electricity, tiltable reflectors have been introduced in the construction to focus radiation onto the solar cells. The reflectors make it possible to contro

A First-in-Man Study of the Reitan Catheter Pump for Circulatory Support in Patients Undergoing High-Risk Percutaneous Coronary Intervention

Objectives: To investigate the safety of a novel percutaneous circulatory support device during high-risk percutaneous coronary intervention (PCI). Background: The Reitan catheter pump (RCP) consists of a catheter-mounted pump-head with a foldable propeller and surrounding cage. Positioned in the descending aorta the pump creates a pressure gradient, reducing afterload and enhancing organ perfusio

Total Zinc Intake May Modify the Glucose-Raising Effect of a Zinc Transporter (SLC30A8) Variant A 14-Cohort Meta-analysis

OBJECTIVE-Many genetic variants have been associated with glucose homeostasis and type 2 diabetes in genome-wide association studies. Zinc is an essential micronutrient that is important for beta-cell function and glucose homeostasis. We tested the hypothesis that zinc intake could influence the glucose-raising effect of specific variants. RESEARCH DESIGN AND METHODS-We conducted a 14-cohort meta-

Suzuki reaction catalysed by a PCsp3P pincer Pd(II) complex: Evidence for a mechanism involving molecular species

{Cis-1,3-bis[(di-tert-butylphosphino)methyl]cyclohexyl}palladium(II)trif luoroacetate (1) acts as a precatalyst for the Suzuki reaction of aryl halides with phenylboronic acid in the absence or presence of mercury to give the product in modest to reasonably good yields. The reaction was monitored by P-31- and H-1 NMR spectroscopy in a stepwise fashion, concluding that complex 1 reacts with activat

Blodplasma används som läkemedel. : Men nationella, evidensbaserade behandlingsriktlinjer saknas

There are great regional variations in the use of plasma products. Evidence-based guidelines for plasma treatment are lacking. The Swedish market offers a non-commercial plasma product, produced by the hospital-based transfusion departments. There is also the commercial, virus-inactivated “SD plasma”. This is more expensive than the non-commercial plasma, yet it has not been shown to reduce the ri

Family and School Psychosocial Environment (FSPE): Development of a brief questionnaire measuring perceived psychosocial environments in children/siblings

Persson, B. (2011). Family and School Psychosocial Environment (FSPE): Development of a brief questionnaire measuring perceived psychosocial environments in children/siblings. Scandinavian Journal of Psychology. The aim of the study was to develop a short Swedish standardized, factor analyzed and cross-validated, family and school psychosocial environment questionnaire (FSPE). The study was based

Engineering Cofactor Preference of Ketone Reducing Biocatalysts: A Mutagenesis Study on a γ-Diketone Reductase from the Yeast Saccharomyces cerevisiae Serving as an Example

The synthesis of pharmaceuticals and catalysts more and more relies on enantiopure chiral building blocks. These can be produced in an environmentally benign and efficient way via bioreduction of prochiral ketones catalyzed by dehydrogenases. A productive source of these biocatalysts is the yeast Saccharomyces cerevisiae, whose genome also encodes a reductase catalyzing the sequential reduction of

Människan och hunden under yngre stenålder : ett förändrat liv.....

New roles for dogs and humansBased on the archaeological finds during the Neolithic we interpret the relationship between humans and their dogs to have significantly changed. People gained an increased understanding of the dog's different, unique properties. The dogs were stimulated by the work and collaboration, and probably developed mentally. Maybe, dogs specialized in different tasks?The dogs

Prediction of endometrial malignancy in women with postmenopausal bleeding and sonographic endometrial thickness ≥ 4.5 mm.

OBJECTIVE: To build mathematical models to evaluate the individual risk of endometrial malignancy in women with postmenopausal bleeding and sonographic endometrial thickness ≥ 4.5 mm using clinical data, sonographic endometrial thickness and power Doppler ultrasound findings. METHODS: Of 729 consecutive patients with postmenopausal bleeding, 261 with sonographic endometrial thickness ≥ 4.5 mm and

Design of RF Properties for Vertical Nanowire MOSFETs

The RF performance of vertical nanowire metal-oxide-semiconductor field-effect transistors in realistic layouts has been calculated. The parasitic capacitances have been evaluated using full 3-D finite-element method calculations, combined with self-consistent Schrodinger-Poisson calculations for the intrinsic gate capacitances. It is shown that a performance comparable to planar FETs can be achie

Towards programmatic design research

The notion of design research entails research where design practice forms part of the knowledge production. Based on our characterization of the nature of design, we propose to conceptualize this kind of research as programmatic design research. Two ongoing PhD projects in interaction design are presented as examples of programmatic research processes, highlighting issues to do with the virtues a
