A population-based serosurvey of Human Herpesvirus type 8 (HHV8) in Vasterbotten county, an area of Northern Sweden with high incidence of Kaposi's Sarcoma, was conducted. Serum samples from an age- and sex-stratified random sample of 520 subjects (260 men and 260 women) participating in a population-based biobanking project were tested for antibodies against HHV8, using a sensitive indirect immun
Aim: To analyse morbidity and mortality in healthy newborn infants in relation to various routines of post-natal follow-up. Design: cross-sectional study. Setting: maternity care in Sweden. Population: healthy infants born at term between 1999 and 2002 (n = 197 898). Methods: Assessment of post-natal follow-up routines after uncomplicated childbirth in 48 hospitals and data collected from the Swed
The pine sawfly Neodiprion sertifer (Geoffroy) uses the acetate or propionate of (2S,3S,7S)-3,7-dimethyl-2-pentadecanol (diprionol) as pheromone components, with the (2S,3R,7R)-isomer being antagonistic, synergistic, or inactive according to the population tested. In this study, we tested the attraction of males to the acetates of three analogs of diprionol, each missing one methyl group, viz. (2S
Massive MIMO can greatly increase both spectral and transmit-energy efficiency. This is achieved by allowing the number of antennas and RF chains to grow very large. However, the challenges include high system complexity and hardware energy consumption. Here we investigate the possibilities to reduce the required number of RF chains, by performing antenna selection. While this approach is not a ve
Quantum memories are used for storing the quantum mechanical states of photons and release identical photons at a later time. This has many applications within the field of quantum computing and is also essential in order to achieve long range quantum communication and cryptography. In this thesis Atomic frequency comb (AFC) quantum memories were investigated. In particular, three-level memory sch
The extent of today's land degradation and desertification in the arid, semi-arid. and sub humid regions of China is a serious threat to the social and economic development in these areas. A national programme for monitoring and classification of drylands has been implemented by the Chinese Academy of Science. Areas are classified into degrees of desertification on the basis of vegetation cove
Patienter som vårdas på intensivvårdsavdelningen (IVA) är kritiskt sjuka. Inter-nationella samt nationella studier visar på att många patienter kan efter att ha vårdats på IVA, få psykiska besvär så som ångest, depression och posttraumatisk stress (PTSD). En bidragande faktor för att utveckla dessa besvär har visat sig vara obehagliga och traumatiska minnen. Syftet med studien var att beskriva pat
Popular Abstract in Swedish Extracellulär matrix är namnet på det molekylära nätverk vilket finns mellan celler i flercelliga organismer. Det består av socker och proteiner organiserade i olika vävnadsspecifika nätverk. Två huvudformer finns, basalmembran och interstitiell extracellulär matrix. Basalmembran ligger som en tunn filt under epitel- och endotelceller, runt fettväv, muskler och periferaBasement membranes are sheet like structures underlying epithelial, endothelial, adipocytes, muscle and peripheral nerve cells. Laminins are an important family of basement membrane proteins implicated in various biological functions through their interactions with cell surface receptors. Laminins are trimers composed of a, b and g chains. Integrins, dystroglycan and other transmembrane glycoprote
Popular Abstract in English There is a natural tendency to take advantage of the most convenient energy source available. In this usage, convenient may mean most abundant, easiest to harvest or simplest to handle. Convenient will also correspond to cheapest in many instances. However, some consider it a responsibility to think of the long term costs of the energy we use. No form of energy is free The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. The burner was operated using methane and three s
Scope: Lingonberries have been shown to reduce the detrimental effects of high-fat diet (HFD) on weight gain, plasma glucose, and inflammation. However, the extent of effects was recently shown to vary between different batches of berries. Here, we examine the metabolic response to two independent batches of lingonberries. Methods and results: Alterations in the phenotype and circulating metabolom
We recently reported that differential gene expression and DNA methylation profiles in blood leukocytes of apparently healthy smokers predicts with remarkable efficiency diseases and conditions known to be causally associated with smoking, suggesting that blood-based omic profiling of human populations may be useful for linking environmental exposures to potential health effects. Here we report on
Reduced fibrinolytic capacity due to increased plasminogen activator inhibitor-1 (PAI-1) activity in plasma is a common finding in patients with coronary heart disease or venous thromboembolism, although its clinical significance is debated. Recently, a dimorphism in the PAI-1 promoter (4G-5G) has been reported and homozygosity for the 4G allele is associated with increased transcription and highe
All-polymer blends are promising materials for organic electronics. Their performance critically depends on the quality of mixing of the electron donor and acceptor polymers and on the local chain organization. We investigated spatially resolved photoluminescence properties of as-prepared and annealed blends of poly[2,3-bis(3-octyloxyphenyl)quinoxaline-5,8-diyl-alt-thiophene-2,5-diyl] (TQ1) and po
When new buildings are constructed the indoor climate for the first period may differ from the one after some years due to various factors, for example may the emissions from the building materials be higher, possibly affecting the air quality, and the balancing of the technical systems; the mechanical supply and exhaust system and heating may not be completely finished. The perceived indoor clima
STUDY QUESTION Does an intensive weight reduction programme prior to IVF increase live birth rates for infertile obese women? SUMMARY ANSWER An intensive weight reduction programme resulted in a large weight loss but did not substantially affect live birth rates in obese women scheduled for IVF. WHAT IS ALREADY KNOWN Among obese women, fertility and obstetric outcomes are influenced negatively wit
The metabolic effects associated with intake of different dietary protein sources are not well characterized. We aimed to elucidate how two diets that varied in main protein sources affected the fasting and postprandial serum metabolites and lipid species. In a randomized controlled trial with crossover design, healthy adults (n = 20) underwent a 4-week intervention with two balanced diets that va
Understanding the relationships between snow and vegetation is important for interpretation of the responses of alpine ecosystems to climate changes. The Qinghai-Tibetan Plateau is regarded as an ideal area due to its undisturbed features with low population and relatively high snow cover. We used 500 m Moderate Resolution Imaging Spectroradiometer (MODIS) datasets during 2001–2010 to examine the
Removal of cyprinid fish is a widely used biomanipulation tool to transform turbid shallow eutrophic lakes in north temperate regions into a clear water state. We here evaluate the removal of cyprinids from streams as a supplement to lake fishing. Since cyprinids often aggregate in high densities in lake inlet/outlet streams during winter migration, removal of fish in this space-confined habitat m
