In the North Sea, Tripos and Dinophysis are commonly occurring mixotrophic planktonic dinoflagellate genera. In order to understand their bloom dynamics, an occurring bloom dominated by T. furca and D. norvegica was followed for several days. High cell abundances of these species were located to estimate: in situ growth rates from cell cycle analyses, depth distributions, growth rates sustained by
Background: OBQ11 was developed in a Swedish context. To evaluate occupational balance, accurate self-rating instruments in the native language are needed. Aim: The aim was to investigate the measurement properties of the Danish version of OBQ11, using the Rasch analysis. Method: Data for the analysis of the Danish version of OBQ11 (OBQ11-DK) was gathered online, and all full data records (n 366)
Background: Multiple sclerosis (MS) is the most common chronic demyelinating disease of the central nervous system and the major non-traumatic cause of permanent disability in young adults. Several migration studies have been performed over the years suggesting a pattern of higher disease disability in certain ethnic groups. To our knowledge, differences in disease progression in immigrants have n
Background: The registry-based randomized VALIDATE-SWEDEHEART trial (NCT02311231) compared bivalirudin vs. heparin in patients undergoing percutaneous coronary intervention (PCI) for myocardial infarction (MI). It showed no difference in the composite primary endpoint of death, MI, or major bleeding at 180 days. Here, we report outcomes at two years. Methods: Analysis of primary and secondary endp
BACKGROUND: Pain is common in individuals with cerebral palsy (CP) and the most reported pain site is the foot/lower leg. We analyzed the prevalence of pain in the foot/lower leg and the associations with age, sex, gross motor function, and clinical findings in individuals with CP.METHOD: This was a cross-sectional register-study, based on data reported to the Swedish Cerebral Palsy Follow-up Prog
Objective: Individuals with psychiatric illness suffer from poorer physical health compared with the general population and have a higher risk of developing cardiovascular and metabolic diseases. This cross-sectional study aims to describe the prevalence of lifestyle and cardiovascular risk factors and the association with self-reported psychiatric symptoms in a population of 40-year-old individua
This thesis documents the design and fabrication of ceramic loudspeaker horns using slip casting and digital fabrication tools, and evaluates their acoustic performance against geometrically equivalent 3D printed PLA reference horns. Two horn profiles were developed and realised through a workflow combining mathematical profile generation, CAD modelling, 3D printing, and slip casting. The acousti
This study investigates the relationship between students’ perceived confidence in handling phishing emails and their responses to simulated phishing attempts, with a particular focus on differences between IT and non-IT students. Using a primarily quantitative survey consisting of seven simulated email scenarios, the study examines how students distinguish between legitimate and potentially malic
Background: Students can practice learning in an interprofessional environment during their education in order to enable a well-functioning cooperation between healthcare professions. The aim of interprofessional learning (IPL) is for all students to contribute with their expertise and work in teams under supervision, which has been shown to improve their understanding of their own and each other’
he purpose of the present study was to empirically test the suggestion that experiential avoidance in an emotion regulation context is best understood as an emotion regulatory function of topographically distinct strategies. To do this we examined whether a measure of experiential avoidance could statistically account for the effects of emotion regulation strategies intervening at different points
Ecosystem phenology plays an important role in carbon exchange processes and can be derived from continuous records of carbon dioxide (CO2) exchange data. In this study we examined the potential use of phenological indices for characterizing cumulative annual CO2 exchange in four contrasting northern peatland ecosystems. We used the approach of Jonsson and Eklundh (2004) to derive a set of phenolo
The development of inhibitory antibodies to factor VIII (FVIII) or factor IX (FIX) in patients with haemophilia is a serious complication of treatment with coagulation factor concentrates. Antibodies develop in 10-15% of haemophilia A and in up to 5% of haemophilia B patients. Several strategies have been developed over the years to facilitate the eradication of inhibitors and reduce the cost. The
A senescent phenotype in endothelial cells is associated with increased apoptosis, reduced endothelial nitric oxide synthase (eNOS) and inflammation, which are implicated in arterial dysfunction and disease in humans. We tested the hypothesis that changes in microRNAs are associated with a senescent phenotype in human aortic endothelial cells (HAEC). Compared with early-passage HAEC, late-passage
Objective - Degradation of extracellular matrix plays an important role in growth and destabilization of atherosclerotic plaques. Cystatin C, inhibitor of the collagen- and elastin-degrading cysteine proteases of the cathepsin family, is produced by virtually all cell types. It is present in the normal artery wall but severely reduced in human atherosclerotic lesions. Methods and Results - To dete
Background & Aims: In the stomach, Helicobacter pylori is found both in the mucus layer and adhering to the gastric epithelium. The aim of this study is to characterize the binding of H. pylori to human gastric mucins. Methods:H. pylori strains that bind the Lewisb (Leb) structure (via the BabA adhesin) and/or sialylated structures, along with isogenic adhesion deletion mutants, were used to i
Extraskeletal myxoid chondrosarcoma (EMC) is a soft-tissue neoplasm cytogenetically characterized by the translocations t(9;22)(q22;q11-12) or t(9;17)(q22;q11), generating EWS/CHN or RBP56/CHN fusion genes, respectively. In the present study, 18 EMCs were studied both cytogenetically and at the molecular level. Chromosomal aberrations were detected in 16 samples: 13 with involvement of 9q22 and 22
BACKGROUND: Different P-wave morphologies during sinus rhythm as displayed on standard ECGs have been postulated to correspond to differences in interatrial conduction. OBJECTIVE: The purpose of this study was to evaluate the hypothesis by comparing P-wave morphologies using left atrial activation maps. METHODS: Twenty-eight patients (mean age 49 +/- 9 years) admitted for ablation of paroxysmal at
The sintering of alumina-supported nickel particles has been studied after heat-treatment in ammonia + hydrogen at 523 K and 250 bar. The investigated samples were nickel supported on gamma-alumina, transalumina and alpha-alumina, and co-precipitated nickel oxide-alumina. The sintering process was mainly followed by hydrogen chemisorption. The samples were also characterised by specific surface ar
The progress of enzymatic peptide synthesis catalyzed by α-chymotrypsin and subtilisin from Bacillus subtilis strain 72 (subtilisin 72) in low-water systems was studied. The initial reaction mixture consisted of the solvent, the acyl-group donor (MalAlaAlaPheOMe or ZAlaAlaPheOMe, Mal, maleyl, Z, benzyloxycarbonyl), the nucleophile XaaNH2 (Xaa = Phe, Leu or Ala), and the enzyme adsorbed on porous s
