Arson in Swedish Schools : A Societal Problem on the Rise

In 2007, Brandforsk – the Swedish Fire Research Board – initiated a research program to provide an overview of research needs coupled to ”arson” in Sweden. A total of six different Swedish universities and research institutes were involved in different projects in the research program. These projects involved both technical aspects fire detection and fire compartmentation as well as sociological i

Adjuvant Treatment of Graves' Disease with Diclofenac : Safety, Effects on Ophthalmopathy and Antibody Concentrations

BACKGROUND: Orbital morphological changes are often present in patients with Graves' disease (GD) already at diagnosis, and cyclooxygenase type 2 (COX-2) is overexpressed in active Graves' ophthalmopathy (GO).OBJECTIVE: To investigate if adjuvant treatment of GD with the COX inhibitor and peroxisome proliferator-activated receptor-γ (PPAR-γ) antagonist diclofenac decreases the development of ophth

A novel vitronectin-binding protein of Pseudomonas aeruginosa for effective infection of the airways

Objectives Pseudomonas aeruginosa is a Gram-negative species that causes chronic and acute infections of the lung, skin, urinary tract and eyes. Most P. aeruginosa isolates are highly resistant to antibiotics and difficult to eradicate due to biofilm formation. The bacterium is known to utilize host proteins by diverse strategies in order to enhance its virulence. Vitronectin is a glycoprotein tha

Vitronectin is produced in the lung upon infection by respiratory pathogens, and is utilized to evade the innate immunity

Bacterial extracellular vesicles (EVs) are shed during growth by the respiratory pathogens Pseudomonas aeruginosa and Haemophilus influenzae. Vesicles trigger release of antimicrobial compounds and proteins of the complement, which are partly regulated by vitronectin. We hypothesized that vitronectin is elevated in the lungs during pneumonia, that respiratory epithelial cells produce vitronectin u

Farmland conservation

This book is meant as a guide to the evidence available for different conservation interventions and as a starting point in assessing their effectiveness. The assessments are based on the available evidence for the target group of species for each intervention. The assessment may therefore refer to different species or habitat to the one(s) you are considering. Before making any decisions about im

Tumor-tracking radiotherapy of moving targets; verification using 3D polymer gel, 2D ion-chamber array and biplanar diode array

The aim of this study was to carry out a dosimetric verification of a dynamic multileaf collimator (DMLC)-based tumor-tracking delivery during respiratory-like motion. The advantage of tumor-tracking radiation delivery is the ability to allow a tighter margin around the target by continuously following and adapting the dose delivery to its motion. However, there are geometric and dosimetric uncert

Radiotherapy delivery during motion

This paper discusses the 3D dosimetric consequences of radiotherapy delivery during two kinds of motion, (i) the respiratory motion by the patient and (ii) the motion by the gantry while rotating around the patient. Respiratory motion primarily compromises treatments in the thorax and abdomen regions. Several strategies to reduce respiratory motion effects have been developed or are under developm

RapidArc treatment verification using polymer gel dosimetry

The aim of this study was to verify a novel volumetric arc therapy technique, RapidArc". Polymer gel dosimetry system was used to measure the advanced inhomogeneous 3D dose distribution produced using the technique RapidArc". A preclinical installation of the novel beam delivery approach was set up on a linear accelerator at Rigshospitalet in Copenhagen. A prostate treatment plan was delivered to

Reduced production and uptake of lactate are essential for the ability of WNT5A signaling to inhibit breast cancer cell migration and invasion

Here we investigated the impact of WNT5A signaling on aerobic glycolysis and evaluated its effects on breast cancer cell migration/invasion. WNT5A signaling reduced migration and lactate production and caused selective down-regulation of the glycolytic enzyme phosphofructokinase platelet-type (PFKP). These events occurred in parallel with a WNT5A-induced inhibition of β-catenin signaling. Support

Wild-goose chase, no predictable patient subgroups who benefit from meniscal surgery : patient-reported outcomes of 641 patients 1 year after surgery

BACKGROUND: Despite absence of evidence of a clinical benefit of arthroscopic partial meniscectomy (APM), many surgeons claim that subgroups of patients benefit from APM.OBJECTIVE: We developed a prognostic model predicting change in patient-reported outcome 1 year following arthroscopic meniscal surgery to identify such subgroups.METHODS: We included 641 patients (age 48.7 years (SD 13), 56% men)

Establishing outcome measures in early knee osteoarthritis

The classification and monitoring of individuals with early knee osteoarthritis (OA) are important considerations for the design and evaluation of therapeutic interventions and require the identification of appropriate outcome measures. Potential outcome domains to assess for early OA include patient-reported outcomes (such as pain, function and quality of life), features of clinical examination (

Malignancies In Giant Cell Arteritis : A Population-Based Cohort Study

OBJECTIVE: To investigate the risk of cancer in patients with biopsy-proven giant cell arteritis (GCA) from a defined population in southern Sweden.METHODS: The study cohort consisted of 830 patients (mean age at GCA diagnosis was 76.3 years, 74 % women) diagnosed with biopsy-proven GCA between 1997 and 2010. Temporal artery biopsy results were retrieved from a regional database and reviewed to as

Importance of the 3' untranslated region of ornithine decarboxylase mRNA in the translational regulation of the enzyme

Translational regulation of ornithine decarboxylase (ODC), which catalyses the first step in the biosynthesis of polyamines, appears to be an important mechanism in the strong feedback control as well as in the hypotonic induction of the enzyme. However, the exact mechanisms are not yet understood. The ODC mRNA has long 5' and 3' untranslated regions (UTRs) which may be involved in the translation

Kan föräldraförberedelse under graviditeten ge tryggare föräldrar efter förlossningen?

Svensk forskning visar att nyblivna föräldrar önskar att de varit mer förberedda på vad som kommer efter förlossningen men få studier har undersökt hur blivande föräldrar kan förberedas inför den första tiden efter förlossningen. Nu startar ett forskningsprojekt för att utveckla en modell för föräldraförberedelse som ska baseras på föräldrarnas behov.
