A large outbreak of enterohaemorrhagic Escherichia coli (EHEC) infections occured in southern Sweden during autumn 2002. A matched case-control study was performed and indicated an association between consumption of fermented sausage and EHEC infection (odds ratio 5.4, P<0.002). Pulsed-field gel electrophoresis analysis identified a strain of E. coli O157:H7 in clinical faecal isolates which was i
Transmembrane (TM) alpha-helical peptides with neutral flanking residues such as tryptophan form highly ordered striated domains when incorporated in gel-state 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) bilayers and inspected by atomic force microscopy (AFM) (1). In this study, we analyze the molecular organization of these striated domains using AFM, photo-cross-linking, fluorescence spec
One of the five largest mass extinctions of the past 600 million years occurred at the boundary of the Triassic and Jurassic periods, 201.6 million years ago. The loss of marine biodiversity at the time has been linked to extreme greenhouse warming, triggered by the release of carbon dioxide from flood basalt volcanism in the central Atlantic Ocean. In contrast, the biotic turnover in terrestrial
Cinnamoyl-CoA reductase (CCR), an enzyme central to the lignin biosynthetic pathway, represents a promising biotechnological target to reduce lignin levels and to improve the commercial viability of lignocellulosic biomass. However, silencing of the CCR gene results in considerable flux changes of the general and monolignol-specific lignin pathways, ultimately leading to the accumulation of variou
Although the main aim of clubfoot correction is to create a foot without limitations in daily activities and sport, studies on the walking capacity of children with corrected clubfeet are rare. In this cross-sectional study, the outcome of the six-minute walking test in 44 children with clubfeet (16 unilateral and 28 bilateral, mean age 8.57±2.45 years) was compared with the reference values of Ge
. The aim of this article is to provide an up-to-date overview on paediatric haemophilia care in the world, with emphasis on medical treatment, rehabilitation, and orthopaedic surgery. The reason these specific professions caregivers are included is that over 90% of bleeding episodes in people with haemophilia (PWH) occur within the musculoskeletal system; and of these 80% of bleedings occur in jo
The popliteal artery (PA) is, after aorta, the most common site for aneurysm formation. Why the PA is more susceptible than other peripheral muscular arteries is unknown. We hypothesized that the wall composition, which in turn affects wall properties, as well as the circumferential wall stress (WS) imposed on the arterial wall, might differ compared to other muscular arteries. The aim was to stud
Popular Abstract in Swedish Diabasgångar (eng. dolerite dykes) bildas när järn- och magnesiumrika (mafiska) smältor från manteln transporteras upp genom jordskorpan och så småningom kyls av och kristalliserar i sprickor på djupet. Gångarna kan bli hundratals meter breda och kan uppträda i stort antal och bilda s.k. gångsvärmar vilka är uttryck för perioder då jordskorpan har utsatts för extensioneDolerite dykes are formed when iron- and magnesium-rich (mafic) mantle-derived magmas ascend through the lithosphere (upper part of the mantle) and crystallize as ‘hydro-fractures’ within the crust. Dykes may exist in great numbers to form dyke swarms (linear or radiating), which can be linked to time periods of continental break-up, or attempted break-up events, associated with voluminous volcani
The influence of temperature, salts, pH, and various pre-treatments and cleaning on the nanofiltration (NF) performance of thin-film polyamide (PA) composite membranes has been investigated. The change in membrane performance was correlated to membrane swelling or/and electroviscous friction. Aspects of costs and energy demand while using NF at elevated temperatures were also evaluated. The increa
It is recommended that intervention thresholds should be based on absolute fracture risk, but there is a large variation in hip fracture incidence from different regions of the world. The aim of this study was to examine heterogeneity of hip fracture probability in different regions from recent estimates of hip fracture incidence and mortality to adjust intervention thresholds. Ten-year probabilit
This study examined human listeners’ ability to classify domestic cat vocalisations (meows) recorded in two different contexts; during feeding time (food related meows) and while waiting to visit a veterinarian (vet related meows). A pitch analysis showed a tendency for food related meows to have rising F0 contours, while vet related meows tended to have more falling F0 contours. 30 listeners judg
In many European universities, English is today used as a medium of instruction. One of the reasons is that it is believed that using English as a medium of instruction (EMI) can develop students’ subject-specific knowledge of English. This knowledge is seen as an asset in the workplace and often presented as providing a competitive advantage supporting professional success. The design of many edu
In this article, we analyze the nexus between political regimes and external voting rights. Using a global longitudinal dataset, we report that higher levels of inclusion and contestation bring higher probabilities that a state adopts and implements emigrant enfranchisement. Taking outliers from our quantitative assessment, we then further examine two liberal democracies, Ireland and Uruguay, and
In scenarios coined Maxwell's demon, information on microscopic degrees of freedom is used to seemingly violate the second law of thermodynamics. This has been studied in the classical as well as the quantum domain. In this paper, we study an implementation of Maxwell's demon that can operate in both domains. In particular, we investigate information-to-work conversion over the quantum-to-classica
Hypoxia hampers eutrophication reduction efforts by enabling high nutrient fluxes from sediment to bottom waters. Oxygenation of hypoxic water bodies is often proposed to reduce benthic ammonium and phosphate release. This study investigates the functional response of benthic nitrate-reducing processes to a long-term engineered oxygenation effort in a density-stratified fjord with euxinic bottom w
Att ha en religion, tro eller övertygelse är en absolut mänsklig rättighet och får inte begränsas på något vis. Friheten att utöva sin religion eller övertygelse är också en skyddad rättighet, dock behöver den begränsas för att inte kränka andra individers friheter och rättigheter. I vilken utsträckning en arbetsgivare kan begränsa en arbetstagares religiösa uttryck på arbetsplatsen är ett omdebat
The implementation of iris scan technology in the context of humanitarian financial assistance in UNHCR-run refugee camps raises an array of legal questions. While the collection and storage of biometrical data in other contexts is often accompanied by a critical discussion about data protection and privacy concerns, the use of such data in humanitarian settings is often left uncontested. The in-d
Geokronologi och paleomagnetiska studier är de viktigaste verktygen för paleogeografiska rekonstruktioner kring hur kontinenter fårhållit sig relativt till varandra under geologisk tid. Genom att jämföra s.k. polvandringskurvor och tidpunkter för storskaliga magmatiska händelser mellan olika krustala block (kontienter/kratoner) kan vi få en bättre förståelse av hur dessa block förhöll sig relativtRobust geochronology and well-constrained paleopoles are the main tools for paleogeographic reconstructions. Through the completion of so called barcode diagrams (matching of coeval events of mafic magmatism between blocks) and determination of the apparent polar wander paths, these studies provide a better understanding of the position of continents and supercontinents in the past. The robust U–P
