Computational approaches are essential to study the effects of inborn and somatic variations. Results from such studies contribute to better diagnosis and therapies. Primary immunodeficiencies (PIDs) are rare inborn defects of key immune response genes. Somatic variations are main drivers of most cancers. Large and diverse data on PID genes and proteins can enable systems biology studies on their

The emulsion stabilization functionality of surfactants and biopolymers can be replaced by solid particles adsorbed at the interface, where they create a category of emulsions known as Pickering emulsions. Recently, health and environmental concerns have led to new market demand for natural, biodegradable and renewable sources of ingredients. Starch granules meet these ingredient requirements and

Dextrose syrups are produced from starch by liquefaction combined with saccharification. In the conventional production process, rotary vacuum filters (RVFs) with a diatomaceous earth (kieselguhr) coating as filter aid are often used for removal of the so-called mud phase after the liquefaction and saccharification step. This mud phase consists of insoluble impurities and suspended solids such as

Stopovers play a crucial role for the success of migrating animals and are key to optimal migration theory. Variation in refuelling rates, stopover duration and departure decisions among individuals has been related to several external factors. The physiological mechanisms shaping stopover ecology are, however, less well understood. Here, we explore how immune function and blood parasite infection

Subsidiarity was one important issue in the snuff discussion within the Community during the first years of the 90s. The purpose was to allow Swedes to continue their age-old habit of putting moist tobacco under the upper lip.6 The snuff debate touched upon Community concepts which will again be of relevance in the lGC 1996. The legality, subsidiarity and proportionality principles were all referr

This dissertation is a study of the Christian thematics in the novels of Christine Falkenland. It has two basic aims. First, to demonstrate how Christine Falkenland writes herself into, and becomes a distinct voice in, a Christian literary tradition, while simultaneously breaking with this tradition by staging and portraying modern people’s questioning of the Christian worldview. Second, to uncove

The paper is an analysis of Klas Östergren's book, Gentlemen, from a sociological perspective.As a sociologist when I read Gentlemen, Östergren’s voice in the book rapidly became associated with Karl Manheim’s concept of the free-floating intelligentsia (Ideology and Utopia, 1954). Östergren uses the tension between distance and closeness, integrating different perspectives, to present himself as

Popular Abstract in Swedish I samband med en kärlskada startar en kaskad av reaktioner som leder fram till bildandet av ett blodkoagel. Det är viktigt att bildandet av blodkoagel begränsas till det skadade området. Blodkoagulationen är därför reglerad av antal antikoagulanta system av vilka det viktigaste är protein C systemet. I detta system samverkar aktivt protein C (APC) tillsammans med ett anProtein S functions as a cofactor to activated protein C (APC) in the degradation of factors Va and VIIIa. In plasma protein S circulates in two forms; 30-40 % circulates as free protein S molecules while the remaining 60-70 % exists in a 1:1 complex with C4b-binding protein (C4BP). Only the free form of protein S functions as a cofactor to APC. Protein S is a mosaic protein composed of four discr

Objective: To determine factors associated with higher degree of meniscal body extrusion in overweight and obese women at high risk of knee osteoarthritis (OA). Design: We used baseline data of the PRevention of knee Osteoarthritis in Overweight Females (PROOF) study, Netherlands, comprising overweight or obese women aged 50-60 years, free of clinical knee OA. All subjects completed a questionnair

Introduction: We wanted to determine vitamin D status after gestational diabetes mellitus (GDM) and to evaluate whether levels of 25-hydroxyvitamin D3 (25OHD3) are associated with beta cell function, insulin resistance or a diagnosis of diabetes after GDM. Material and methods: Glucose homeostasis was assessed during a 75-g oral glucose tolerance test one to two years after delivery in 376 women w

Popular Abstract in Swedish Fysiologiska och kliniska aspekter på förändrad kapillärpermeabilitet Graden av genomsläpplighet (permeabilitet) i de minsta blodkärlen (kapillärerna), där utbytet av näringsämnen och slaggprodukter sker, är avgörande för att kroppens celler skall fungera. I den svåraste fasen av sjukdomar såsom blodförgiftning (sepsis) och efter trauma är permeabiliteten ökad varvid plMicrovascular permeability is important for exchange of fluids and proteins in health and in disease. Permeability increases in critical illness, such as during sepsis/SIRS and after trauma, and may be affected by drugs. Increased permeability causes oedema and hypovolaemia. Hypovolaemia is treated with fluids, and their efficacy is determined by their intravascular retention, also influenced by t

This book has come out of the work of the European ‘ATHENA’ Thematic Network, which is a network of higher education institutions involved in feminist research and in delivering Women’s Studies and Gender Studies programmes. Women’s Studies have developed a particular pedagogic focus that values both recognition of the ‘personal’ and critical reflective thinking in learning communities. Feminist

Popular Abstract in Swedish Huvudsyftet med avhandlingen är att formulera en teoretiskt och empiriskt förankrad konsultationsmodell för psykologer i skolsammanhang. Idéer och handlingsstrategier tydliggörs så att de kan tillämpas, värderas och vidareutvecklas av andra yrkesutövare. De tänks även kunna utgöra en referensram för psykologers, specialpedagogers och andra specialisters teamarbete. VidaThe primary aim of this thesis is to formulate a theoretically and empirically based consultation model for psychologists in school contexts. Ideas and strategies are clarified so that they can be applied, evaluated, and further developed by other professionals. The model has been constructed with an interactional approach, with the stress on patterns of interaction between grown-ups and children

Acquired brain injuries can lead to cognitive, emotional as well as behavioural sequelae and can have a great impact on the affected person and his or her family. Over the last decade, pharmacological treatment has become an important part of brain injury rehabilitation. There is increasing clinical experience of the use of various drugs affecting neurotransmitters and cerebral function, but the s

Popular Abstract in Swedish ”Behandlingen av trafikflöde vid trafiksäkerhetsanalyser - ett icke-parametriskt angreppssätt applicerat på oskyddade trafikanter” Det finns en lång tradition av att beakta trafikflöden inom trafiksäkerhetsområdet. Inverkan av flödet har dock ofta betraktats som så självklart att det använts utan eftertanke. I denna avhandling kan jag däremot visa att relationen mellaThe treatment of flow in the area of traffic safety has a long tradition. The influence flow has on the number of accidents is, however, often considered so obvious that it tends to be trivial. In this thesis I can show that the relation between flow and accidents holds interesting information. In order to compare countermeasures, or conduct other types of traffic safety comparisons where the flo

Purpose: Retigabine is a novel anticonvulsant drug that not only augments gamma-aminobutyric acid mechanisms, but also opens voltage gated K+ channels (KCNQ). In this study we investigated the effects of retigabine on detrusor activity in rats. Materials and Methods: To conscious, female Sprague-Dawley rats undergoing continuous cystometry retigabine was given intravenously (0.5, 1 and 5 mg/kg(-1)

Mixtures of ethyl (hydroxyethyl)cellulose (EHEC) and sodium dodecanoate (SDoD) were investigated using surface tension, conductivity and transmittance measurements. The parameters of the surfactant to polymer association processes such as the critical aggregation concentration (cac) and saturation of the polymer by SDoD (psp) were determined from the plots of surface tension and specific conductiv

Endotoxin was measured in air and dust samples collected during four commercial aircraft flights. Samples were analyzed for endotoxin biological activity using the Limulus assay. 3-hydroxy fatty acids (3-OH FA) of carbon chain lengths C10:0-C18:0 were determined in dust by gas chromatography-ion trap tandem mass spectrometry. The geometric mean (geometric standard deviation) endotoxin air level wa
