Frequency Measures in AF. Introduction: Frequency analysis of fibrillation (FAF) and time-frequency analysis (TFA) were developed recently in order to quantify atrial electrical remodeling in atrial fibrillation (AF) from the surface ECG. This article describes the experience with these two different frequency analysis techniques in consecutive AF patients and discusses possible applications in AF
Popular Abstract in Swedish Hemicellulosa är en fantastisk källa av förnyelsebar råvara, vars användning har potental att bli kraftigt utökad i framtiden. Hemicellulosor är tillsammans, med lignin och cellulosa bland de mest förekommande klasserna av ämnen i växtcellernas väggar. Dessa tre beståndsdelar är tätt sammanlänkade, vilket gör det svårt att separera dem från varandra. Hemicellulosor är kHemicelluloses are tremendous sources of renewable raw materials, which utilisation have the potential to be highly increased in the future. Hemicelluloses are among the major groups of compounds in plant cell walls, together with cellulose and lignin. These three components are closely associated, making them difficult to separate from each other. Hemicelluloses are complex polysaccharides and tw
Popular Abstract in Swedish Hur man studerar kommunikation hos tallsteklar Totalt finns det cirka 125 beskrivna tallstekelarter i världen. De tillhör gruppen växtsteklar, och deras larver lever vanligen av tallbarr. Larvernas härjningar kan medföra att träden växer sämre eller rent av dör. Den färdiga stekeln äter inget, utan är helt inriktad på att para sig under sitt 10 –15 dagar korta liv i skPine sawflies (Hymenoptera: Diprionidae) are severe pine defoliators. This thesis investigated sawfly behaviour related to the use of pheromones in integrated pest management, including monitoring with pheromone traps and mating disruption. Neodiprion sertiferr females were placed on pine twigs in the field and 11–30 % of the females that remained on their twig after the first mating re-mated. Onl
Protein phosphorylation in the subcompartments of plant mitochondria was investigated by labelling with [gamma-32P]ATP and by SDS-PAGE/autoradiography. About 20 proteins in inside-out inner mitochondrial membranes from potato tubers were phosphorylated by endogenous protein kinases when incubated with [gamma-32P]ATP. None of the phosphorylated proteins were labelled when using [alpha-32P]ATP as a
Fatty acids (FA) have crucial functions in animals, affecting e.g. inflammatory responses, thermoregulation, and cell membrane fluidity. Diet and ambient temperature affect animals’ FA composition, which, in turn, may influence these physiological processes. Great tit (Parus major) −common in both urban and rural habitats− are mainly granivorous during winter and insectivorous during summer. These
BACKGROUND: Aggregates formed between leukocytes and platelets in the circulation lead to release of tissue factor (TF)-bearing microparticles contributing to a prothrombotic state. As enterohemorrhagic Escherichia coli (EHEC) may cause hemolytic uremic syndrome (HUS), in which microthrombi cause tissue damage, this study investigated whether the interaction between blood cells and EHEC virulence
Biotic and abiotic elicitors induce biosynthesis of secondary metabolites (phytoalexins) as a defense against pathogenic organisms in plants. The use of cell suspension cultures in combination with elicitors offer excellent experimental model systems for studies on various elicitor-induced responses of plant tissues. Various elicitors were added to cell suspension culture of Eschscholtzia californ
Background: Mutations in the PRSS1 gene explain most occurrences of hereditary pancreatitis (HP) but many HP families have no PRSS1 mutation. Recently, an association between the mutation N34S in the pancreatic secretary trypsin inhibitor (SPINK1 or PSTI) gene and idiopathic chronic pancreatitis (ICP) was reported. It is unclear whether the N34S mutation is a cause of pancreatitis per se, whether
Popular Abstract in Swedish I denna avhandling studeras den akuta inflammatoriska reaktionen i huden. Akut inflammation beskrevs redan under romersk tid av Aulus Cornelius Celsus. Han karakteriserade denna reaktion med rodnad, svullnad, värme och smärta. Fysiologiskt består akut inflammation av vidgning av små blodkärl (vasodilatation) som ger upphov till rodnad samt av läckage av plasmaproteiner This thesis examines the microvascular inflammatory response in the skin. The microvascular response includes vasodilatation and plasma exudation. In the first three studies, the combined response was measured in guinea pig skin with a technique based on detection of radiolabelled protein. Transferrin was labelled in vivo by injection of 113mIn and the conversion electrons detected over the skin u
Commercial decabromodiphenyl ether (DecaBDE) is commonly used as a flame retardant in different electrical and textile applications. It is also used in the production of flame-retarded rubber compound. DecaBDE is the major technical polybrominated diphenyl ether (PBDE) in use today and consists mainly of decabromodiphenyl ether(BDE209). PBDEs, including BDE-209, are well-known environmental pollut
Objective To study, in a large cohort, the association between the use of anti-asthmatic drugs during pregnancy and pregnancy complications. Methods Using the Swedish Medical Birth Register, we identified 24,369 women who reported the use of anti-asthmatic drugs in early pregnancy and 7778 women who were prescribed such drugs later during pregnancy by antenatal care system centres, during the peri
The phase behavior of a thermoseparating cationic hydrophobically modified ethylene oxide polymer (HM-EO) containing tertiary amines has been investigated at different pH, salt and sodium dodecyl sulfate (SDS) concentrations, in order to find a water/HM-EO two-phase, system suitable for protein partitioning. The used polymer forms micellar aggregates that can be charged. By changing pH and SDS con
Purpose: The beneficial effects of antimuscarinics on detrusor overactivity and overactive bladder syndrome are exerted during bladder filling, when there is no parasympathetic outflow from the spinal cord. We tested the hypothesis that, if tolterodine exerts some of its effects on afferent nerves, the functional elimination of C-fiber afferents should affect the actions of the drug on urodynamic
Popular Abstract in Swedish Nervrotskompression i nacken - effekter av kirurgi, sjukgymnastik och halskrage. Under de senaste decennierna har besvär från halsrygg och axlar ökat hos befolkningen, medan besvär från ländrygg minskat. En orsak kan vara att tunga lyft i arbetet har minskat, medan sittande arbete med upprepade monotona armrörelser och arbete med framåtböjd nacke t.ex. framför datorskäThe efficacy of surgery, physiotherapy or a cervical collar in the treatment of chronic cervicobrachial pain of radicular origin was evaluated in a prospective, randomised study comprising 81 patients of both sexes, 28-64 years of age, referred for possible neurosurgical treatment. After neurological and radiological examination and giving their informed consent, they were randomised to one of the
Genom reformen en modernare rättegång gjordes möjligheten för parter att närvara vid domstolssammanträden via ljud- och/eller bildöverföring permanent. Användningen av sådana lösningar har ökat under de senaste åren och accelererades av covid-19-pandemin. I experimentell miljö har det återkommande observerats att vittnens och målsägandes utsagor uppfattas som mindre tillförlitliga om de presenterThrough the reform en modernare rättegång [a more modern trial] the possibility for parties to attend court hearings via video and/or audio was made permanent. The use of such solutions has increased over the last years and was accelerated by the covid-19 pandemic. In experimental settings it has repeatedly been observed that witnesses’ and complainants’ testimonies are perceived as less credibl
Beginning in the late 20th century, public libraries in Sweden have been offering its patrons the opportunity to check out films just as they would books. Taking place over the last decade, however, the methods by which we predominantly consume films have gone through major changes – mainly caused by our increased digital presence and, more importantly, the extensive development of popular streami
Background Technological advancements over the last decades have resulted in an increased degree of digitalisation within as well as in between companies around the world. As a result, requirements on companies in general are growing and global competition is steadily increasing. One area for which this is highly relevant, and for which there is still a lot of potential for improvement, is industr
The purpose of this thesis is to answer the question: is it possible to outperform the OMXS30 index by using an investment strategy based on the Black Swan theory? With increased globalization and technological development, the world has become more and more complex and economic models and theories cannot capture all the sources to risk. There are also several limitations to the human mind which m
The traditional art market is currently experiencing a digital transformation and multi-sided platforms (MSPs) for trading art are a major part of this. Much research has been done in the area of MSPs, however, there is a lack of studies in the field of starting such platforms for art. Therefore, this study aims to determine the critical success factors (CSFs) for starting an online art platform (
In August 2007 we went to New Zealand for a placement at Child Youth and Family Services. There our interest in Family Group Conferences (FGC) took off. FGC is not near as common in Sweden as in New Zealand. Therefore the purpose of this study was to examine how the Social Services in Helsingborg and Höör in Sweden and Belfast in Northern Ireland work with FGC. We had the privilege to go to Belfas
