A study to determine and compare the sensitivities and specificities of the comparative cervical tuberculin (CCT) and gamma-interferon (IFN-gamma) tests for the diagnosis of bovine tuberculosis was conducted on 30 zebu oxen. The results of the tests were compared with the presence of acid-fast bacilli found by bacteriological culturing and histopathological examinations. The sensitivity and specif
Palaeomagnetic data from the 337 Ma Mageroy dykes (northern Norway) are of exceptionally high quality, and a positive contact test along with an existing regional result from the Silurian Honningsvag Igneous Suite attests to a primary Early Carboniferous magnetic signature. The palaeomagnetic pole (S 14.8degrees, E320.1degrees, dp/dm = 4.4/8.6degrees) is the first Early Carboniferous pole from Bal
OBJECTIVE: To measure intracellular and tissue pH in periarticular soft tissue during different phases of antigen induced arthritis in the rat. METHODS: pH was calculated using the following values: (1) the distribution of [14C]-dimethyl-oxazolidinedione; (2) the total tissue water and the extracellular space water volume, which was measured as [14C]-sucrose distribution in nephrectomized rats. Ex
In northern Sweden, Empetrum hermaphroditum Hagerup dominates the ground layer vegetation in post fire successions by suppressing other plant species. Previous studies suggest that this negative effect by E. hermaphroditum may be explained, at least in part, by the release of phenolic compounds, particularly batatasin-III, from foliage to soil. In this pilot study, we evaluated the effect of batat
Eight cold-adapted, polygalacturonase-producing yeasts belonging to four species were isolated from frozen environmental samples in Iceland. They were identified as Cystofilobasidium lari-marini, Cystofilobasidium capitatum, Cryptococcus macerans and Cryptococcus aquaticus species by sequence analysis of rDNA regions. Growth behavior of the isolates was investigated. All strains could grow at 2°C.
Stable isotopes have been used to analyse food webs and (or) trace movements of animals for about 30 years. There has been some debate on the use of different tissues and treatments before isotope analysis, as well as on seasonal effects. We found different crayfish (Pacifastacus leniusculus) tissues (muscle, hepatopancreas, exoskeleton, gill, and whole body) to have different isotope values. Lipi
Near- and mid-infrared absorption spectra of pure water and aqueous 1.0 g/dL glucose solutions in the wavenumber range 8000-950 cm(-1) were measured in the temperature range 30-42 C in steps of 2 degreesC. Measurements were carried out with an FT-IR spectrometer and a variable pathlength transmission cell controlled within 0.02 degreesC. Pathlengths of 50 mum and 0.4 mm were used in the mid- and n
Since its development in the 1980s, spark ablation has been widely used to produce nanoparticles (NPs) in the aerosol phase, effectively eliminating surface contamination common in other generation methods (Schmitt-Ott, 2019). This is a significant advantage, as the surface of NPs plays a crucial role in applications such as sensing and catalysis. Additionally, spark ablation enables the productio
BACKGROUND: Prognostication of recovery in patients who are unconscious following cardiac arrest can be guided by concentrations of brain injury biomarkers in the blood. The optimal biomarker and cutoff concentrations for the prediction of outcome remain unknown. In this study, we aimed to evaluate which biomarker of brain injury is most accurate for predicting functional outcome after cardiac arr
Over the past two decades there has been increased interest in orphan drug development for rare diseases. However, hurdles to clinical trial design for these disorders remain. This phase 1a/1b study addressed several challenges, while evaluating the safety and tolerability of the novel oral molecule KL1333 in healthy volunteers and subjects with primary mitochondrial disease.KL1333 aims to normali
Informal carers in paid work are known as working carers (WKCs). This combination of care and work is particular to them, and their support needs may differ from other informal carers. This exploratory study describes the caregiving-related factors associated with experiencing caregiving as demanding and a decreased ability to work in WKCs. The Swedish National Carer Survey was conducted in a stra

Aims of the studies: To apply and compare MR imaging metal artifact reducing sequences (MARS) including subtraction imaging after contrast application in patients with metal-on-metal (MoM) hip prostheses, investigate the prevalence and characteristics of periprosthetic abnormalities, as well as their relation with pain and risk factors. [Paper I]. To evaluate the distortion and artifact area of me
Tasquinimod is an orally active antiangiogenic drug that is currently in phase III clinical trials for the treatment of castration-resistant prostate cancer. However, the target of this drug has remained unclear. In this study, we applied diverse strategies to identify the histone deacetylase HDAC4 as a target for the antiangiogenic activity of tasquinimod. Our comprehensive analysis revealed allo
The Lepidoptera fauna of the Danish island of Anholt is surveyed, and 1160 species are recorded. Anholt is situated in Kattegat 44 km from Denmark and 47 km from Sweden. The history and environment of the island are briefly discussed, with special focus on the flora, and earlier studies of the Lepidopterera fauna of Anholt are dealt with. The present study is in first hand based on material collec
We report our experience with surgery for femoral metastatic lesions, based on 216 patients who underwent a total of 245 operations for femoral metastatic lesions. The median age was 66 (30-94) years, and the most common diagnosis breast cancer, followed by prostate cancer. All patients had pain on weight bearing, 196 had pain at rest, 147 were unable to walk preoperatively, and 148 were confined
Aim: To determine if the use of alcohol-based hand-disinfection as a complement to regular hand washing at daycare centers (DCCs) can reduce the childhood rate of absenteeism. Methods: Children aged 0-6 years attending DCC were studied in a cluster randomized controlled trial during 30 weeks. Thirty matched pairs of DCCs were included in the study, where one of the DCCs was randomized to intervent
A calorimetric method to determine water activity covering the full range of the water activity scale is presented. A dry stream of nitrogen gas is passed either over the solution whose activity should be determined or left dry before it is saturated by bubbling through water in an isothermal calorimeter. The unknown activity is in principle determined by comparing the thermal power of vaporizatio
