Popular Abstract in Swedish Kostfiber visar på gynnsamma effekter på blodsockersvar, inflammationsmarkörer och blodfetter utifrån tre humanstudier som genomfördes i detta arbete. I en av studierna analyserades blod och urin med metabolomik. Det är en metod där man analyserar alla små molekyler (metaboliter) som finns i provet med hjälp av vätskekromatografi kopplat till masspektrometri. Med hjälp It is well-known that dietary fibre can have a positive effect on the development of lifestyle-dependent diseases such as cardiovascular disease and type 2 diabetes. However, the effect may be different for different kinds of fibre and different sub-populations at risk. Therefore, the effects of three different kinds of fibre on postprandial and long-term response in healthy subjects were investig

Popular Abstract in Swedish Denna avhandling behandlar design, tillverkning, karakterisering och optimering av elektroniska komponenter alla baserade på kvantmekanisk tunnling. Tunnling är ett rent kvantmekaniskt fenomen utan någon klassisk motsvarighet, som först blir relevant då dimensionerna krymper ner i nanometerskala (en nanometer är en miljarddel's meter). Då kan elektroner ”tunnla” igenomThis thesis concerns different kinds of tunneling based devices all showing negative differential resistance. The thesis is divided in three parts, resonant tunneling transistors, Esaki diodes and coupled zero dimensional systems. The resonant tunneling transistors are GaAs-based vertical field effects transistors, based on a combination of overgrown tungsten gates and double barrier heterostruct

Popular Abstract in Swedish I alla flercelliga organismer behövs utbyte av information mellan cellerna, som bygger upp kroppen. För detta ändamål är cellerna försedda med små antenner, som kan ta emot signaler och kallas därför receptorer. Receptorer kan vara uppbyggda på olika sätt. De flesta receptorer slingrar sig sju gånger genom membranet och har ett gemensamt sätt att fortleda signaler till Seven-transmembrane, G-protein coupled receptors play a central role in physiology since they facilitate cell communication in multicellular organisms by recognition of a broad range of ligands. They also represent important drug targets. Unfortunately, for many of these receptors the endogenous ligands, and, hence, their physiological functions, remain to be identified. These receptors are usuall

Popular Abstract in Swedish Fågelflyttning omfattar några av de mest fascinerande beteendemässiga anpassningarna vi finner i naturen. Hos många fågelarter flyttar unga fåglar obereoende av erfarna vuxna individer och kräver således medfödd information om flyttningsvägar, rastning och övervintringsområden. Denna information har visat sig bestå av ett nedärvt program som innehåller flyttningsriktninIn many species of birds juveniles migrate independently of experienced adults and thus have to rely on innate information about migratory routes and wintering area. This information is encoded as a set of inherited migratory directions and a timing schedule that provides information on when and how far to migrate. Apart from these remarkable behavioral adaptations, migration also requires several

In northern Sweden, Empetrum hermaphroditum Hagerup dominates the ground layer vegetation in post fire successions by suppressing other plant species. Previous studies suggest that this negative effect by E. hermaphroditum may be explained, at least in part, by the release of phenolic compounds, particularly batatasin-III, from foliage to soil. In this pilot study, we evaluated the effect of batat

This dissertation considers two different aspects of health economics; (i) stated preference methods and (ii) empirical analyses of equity. The first essay deals with the issue of the choice of econometric models when analysing data from a closed-ended contingent valuation survey in health economics. The features of provision, either compulsory or voluntary, and the fact that certain individuals m

A gene encoding a lipolytic enzyme amplified from the alkaliphilic bacterium Bacillus halodurans LBB2 was cloned into the pPICZ alpha B vector and integrated into the genome of the protease deficient yeast strain Pichia pastoris SMD1168H. This previously undescribed enzyme was produced in active form, and cloning in frame with the Saccharomyces cerevisiae secretion signal (alpha-factor) enabled ex

Total antioxidant capacity (TAC), total phenolic compounds (TPH), total flavonoids (TF) and the amounts of individual phenolic compounds were assessed in Bolivian potato cultivars (various Solanum species) before, during and after the traditional freezing and sun-drying of potatoes known as chunos. The TAC of chunos ranged from 0.4 to 2.7 mu mol Trolox equivalents/g dry matter using 2,2'-azino-bis

This paper reports a method to produce a solvent-free extract from green tea leaves with high content of catechins and low content of caffeine, in two steps and using only "green" solvents. The method is based on the pressurized liquid extraction (PLE) of the green tea leaves using ethyl lactate as solvent, followed by a selective precipitation procedure using the supercritical carbon dioxide (SCC

A major bottleneck in high-throughput protein production is the validation step, which is why parallel and automated sample processing methods are highly desirable. Also, a miniaturized sample preparation format is preferred, as the reduction of reagent volumes significantly decreases the analysis cost per sample. We have developed an automated and miniaturized protein sequence verification protoc

Urinary tract infections (UTIs) are clustered in certain individuals but the molecular basis of disease susceptibility is not known. A single gene was shown to control the susceptibility to acute pyelonephritis and renal scarring in mice. The IL-8 receptor homologue (mIL-8Rh) controls neutrophil function during acute infection and the mIL-8Rh deletion causes tissue damage through neutrophil entrap

Popular Abstract in Swedish Polycykliska aromatiska kolväten (PAH) är en grupp organiska ämnen som kan vara giftiga men även starkt cancerframkallande. De bildas vid förbränning av organiskt material vid låg syretillförsel och återfinns i olika produkter som tjära och fossila bränslen. De källor som tillför störst mängd till miljön idag är bostadsuppvärmning med ved, kol och olja (i Sverige ca 2/3Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants of great environmental concern, due to their toxicity, carcinogenicity and long persistence in the environment. To determine the potential risk associated with PAHs released from contaminated soil or waste materials, knowledge is required on the leachable concentrations of PAHs and the amounts available for release. The obj

The kinetic response of an L-3 (sponge) phase formed in the C12E5-n-decane-brine system is studied using the Joule-heating temperature jump (JHTJ) technique. The equilibrium state of the spongelike membrane is instantaneously perturbed, and the kinetic response is monitored using a multi-angle light scattering setup. These measurements yield a time-dependent scattering intensity as a function of t

The concentration of soluble HLA class I (sHLA-I) was measured by ELISA in serum samples from 30 well-characterised SLE patients at high and low disease activity states and from 100 healthy controls. HLA-A allotypes in the patients were analysed by a PCR-based typing technique. A higher level of sHLA-I was found in SLE patient sera both at high and low disease activity than in controls (P< 0.001).

Ischemic heart disease is the leading cause of death in high-income parts of the world and is caused mainly by atherosclerosis in the coronary arteries. The rupture of an atherosclerotic plaque with subsequent platelet activation and clot formation can lead to myocardial infarction (MI). Atherosclerosis is a complex process, which involves the accumulation and oxidation of low-density lipoprotein

Bakgrund: Distanslöpare beskrivs som en grupp som utsätts för hög risk att drabbas av överbelastningsskador som till största del är lokaliserade i den nedre extremiteten. En svag abduktormuskulatur förmodas vara en bidragande faktor till att utveckla överbelastningsskador hos löpare. Det är i dagsläget vanligt med muskelstärkande träning för höftabduktorerna både som rehabiliteringsåtgärd samt i p

I svensk straffprocessrätt har omedelbarhetsprincipen haft stor betydelse sedan rättegångsbalken infördes år 1948. Den innebär att domstolen bara ska döma över det som har framkommit under huvudförhandlingen. Domstolen har inte innan huvudförhandlingen läst polisens utredning, utan parter och vittnen ska komma till domstolen och lämna sin berättelse direkt inför rätten. Den 1 januari 2022 infördeIn Swedish criminal procedure law, the principle of immediateness has been of great significance since the code of judicial procedure came into effect in 1948. This implies that the court should only judge and present verdicts based on what has appeared during the main hearing. Hence, the court will not have read the pre-trial investigation before the main hearing. Instead, the implicated parties

It is widely recognised that the two major challenges of the 21st century are climate change and poverty. The building sector is responsible for over a third of all global carbon dioxide emissions. At the same time, we see vastly overcrowded and rapidly growing informal settlements in developing countries, where people lack the basic right to decent shelter. This is simply not sustainable and forc
