The great polymorphism observed in the major histocompatibility complex (MHC) genes is thought to be maintained by pathogen-mediated selection possibly combined with MHC-disassortative mating, guided by MHC-determined olfactory cues. Here, we partly characterize the MHC class I and II B of the blue petrel, Halobaena caerulea (Procellariiformes), a bird with significant olfactory abilities that liv

Orange is a tropical fruit used in the juice industry, yielding important quantities of by products. The objective of this work was to obtain a dietary fiber-rich orange bagasse product (DFROBP), evaluate its chemical composition and its use in the preparation of a bakery product (muffin). Muffins containing two different levels of DFROBP were studied regarding chemical composition, in vitro starc

Despite its remarkable receptivity to immigrants entering the country, Sweden has one of the worst track records in Europe in terms of employing immigrants. However, although there are various studies devoted to integration issues, little scholarly attention has been directed toward public employment officers and their role as professional mediators in the integration process. By investigating the

Inelastic neutron scattering was used to study the effect of 5 and 40 mol% cholesterol on the lateral nanoscale dynamics of phospholipid membranes. By measuring the excitation spectrum at several lateral q (||) values (up to q (||) = 3 (-1)), complete dispersion curves were determined of gel, fluid and liquid-ordered phase bilayers. The inclusion of cholesterol had a distinct effect on the collect

Popular Abstract in Swedish Omkring 16% av alla cancerfall i världen beräknas vara orsakade av infektioner och omkring 5% av dessa orsakas av humant papillomvirus (HPV). HPV har etablerats som orsak till livmoderhalscancer och kondylom (könsvårtor). HPV-typer som förekommer på hud har förknippats med icke-melanom hudcancer såsom skivepitelcancer (SCC) men också ofarliga hudhudförändringar som aktiAround 5% of all cancer cases worldwide are caused by human papillomavirus (HPV) which has been established as the cause of cervical cancer and genital warts (condylomas). Cutaneous HPV types have been weakly associated with non-melanoma skin lesions such as squamous cell carcinoma (SCC) and actinic keratosis (AK). We have analyzed skin and genital lesions for presence of HPV-DNA in order to searc

We sought to determine the influence of single-nucleotide polymorphisms (SNPs) in RANKL, RANK, and OPG on volumetric bone mineral density (vBMD) and bone geometry at the radius in men. Pairwise tag SNPs (r (2) a parts per thousand yen 0.8) for RANKL (n = 8), RANK (n = 44), and OPG (n = 22) and five SNPs near RANKL and OPG strongly associated with areal BMD in genomewide association studies were pr

An overview of the integration of the Skåne provinces into the Swedish state after 1658, showing that it was done in a way typical of the 17th century European conglomerate states.

The micro-mechanisms of fracture in a laminate composed of an aluminium foil and a polymer film are considered in this study. The laminates as well as the individual layers, with and without premade centre-cracks, were tensile tested. Visual inspection of the broken cross-sections shows that failure occurs through localised plasticity. This leads to a decreasing and eventually vanishing cross-sect

In a previous research project, carried out during the years 2006-2008, the possibility to manufacture wet glued laminated beams using ungraded laminations of Norway spruce side boards was investigated with very promising results.In the project presented in this report, the performance of the wet glued beams has been further investigated and developed as regards grading of side board laminations,

Understanding the genetics of a polymorphic trait is important to predict its likely evolution. In Collinsia heterophylla, the upper petal lip colour can be either be white or white with a purple band, while the lower petal lip colour is invariably purple. Because the corolla is only partly polymorphic, the polymorphism can not have evolved due to a mutation where a pigment was lost in the entire

Det finns många situationer där data är hierarkiskt uppbyggda och där flernivåanalyser kan komma i fråga. Metoderna måste dock anpassas till frågeställningen, och modellerna måste kontrolleras mot data.

The chondroitin/dermatan sulfate proteoglycans (CS/DSPGs), biglycan, decorin, and versican play several important roles in extracellular matrix influencing matrix organization, cell proliferation, and recruitment. Moreover, they bind and regulate growth factors in the extracellular matrix. We have previously shown that cultured human lung fibroblasts treated with transforming growth factor-beta (T

Popular Abstract in Swedish En hjärtinfarkt definieras som celldöd i hjärtmuskeln, och om celldöden är omfattande, orsakar den en oåterkallelig nedsättning i hjärtats pumpfunktion. Pumpfunktionen kan även vara långvarigt nedsatt p.g.a. att hjärtat inte får tillräckligt med blod. Man kan då förbättra pumpfunktionen genom att återställa blodtillförseln med en operation. För att kunna hitta områden iThe assessment of ischemic heart disease (IHD) often focuses on the detection of dysfunctional but viable myocardium which may improve in function following revascularization. Dysfunctional but viable myocardium is identified by distinct characteristics with regards to function, perfusion and viability. Therefore, in Paper I we developed a method for quantitative polar representation of left ventr

The libels written against queen Christina of Sweden are analyzed,and compared to the libels against cardinal Mazarin. Christina is accused of sexual misbehaviour, Mazarin is not. The rules governing the female conduct is clearly different from the rules governing male conduct.

Popular AbstractI den här avhandlingen behandlas dels hur själva organiseringens processer kan gestalta sig, dels innehållet i några av de studerade processerna. Det empiriska materialet i studien har hämtats från fyra industriföretag som alla under 1990-talets första år genomförde försök att utveckla en mera processorienterad arbetsorganisation. Tre av företagen ingår i globala koncerner. Det fjäThe focus of this dissertation is on organizational change in four industrial corporations. A special emphasisis placed upon the symbolic and rhetorical aspects when changing organizations. Main concepts in the study are symbolic management and management of meaning. Two main areas are discussed in the dissertation. Firstly, how the new organizational meaning is constructed or produced. Secondly,

Calmodulin is a Ca2+-dependent regulatory protein in eukaryotic cells involved in a variety of intracellular activities. Many responses to abiotic stresses involve signaling by Ca2+ and Ca2+/calmodulin regulation, including water and salinity stress. To investigate how calmodulin affects germination on media with high concentrations of NaCl, transgenic tobacco plants expressing heterologous calmod

Background & aims Patients with a hip fracture often have a poor nutritional status that is associated with increased risk of complications, morbidity and mortality. The aim of this study was to investigate the effects of an improved care intervention in relation to nutritional status and pressure ulcers. An intervention of best practices for patients with hip fracture was introduced, using t
