Galactolipids: digalactosyldiglyceride (DGalDG), monogalactosyldiglyceride (MGalDG) and sulfoquinovosyldiglyceride (SQDG) are the major lipid components in thylakoid membranes of chloroplasts i.e. the site of photosynthesis in plants. They are the most abundant membrane lipids in nature, and thus important sources of essential fatty acids for herbivores and omnivores. This thesis investigates the
Vasopressin and oxytocin seem to have pivotal roles in the pathophysiology of primary dysmenorrhoea and preterm labour. Prostaglandins are also involved in the regulation of uterine activity with different receptors mediating both stimulation and relaxation. We explored different aspects of synthesis, release and receptor pharmacology of vasopressin and oxytocin. We also tested a vasopressin and o
This thesis deals with the expression, localization and regulation of neuropeptide Y (NPY) in the pancreatic islets of Langerhans under normal and experimental conditions. NPY is widely distributed in the mammalian nervous system and belongs to a family of closely related petides also comprising peptide YY (PYY) and pancreatic polypeptide (PP). NPY exerts a variety of biological effects, such as s
Bone morphogenic proteins, BMPs, are a group endogenous proteins that are highly conserved through evolution. The amino acid sequences of about 15 different BMPs are now known and recombinant human BMPs are commercially available. Implantation of an individual BMP protein is sufficient to induce bone formation even at a subcutaneous site. Our initial studies discovered inhibition of bone formation
This thesis presents a three-year prospective study on metabolic characteristics of impaired glucose tolerance (IGT) and the regulation of insulin sensitivity versus islet function in relation to changes in glucose tolerance. 108 non-diabetic women aged 57-58 years were randomly selected from a population of women born in 1935 with a high prevalence of IGT. At baseline and follow-up, glucose toler
In the last decade, powerful communication and information technology in the form of the mobile phone has been put into the hands of more than 50% of the global population. In stark contrast, a lack of access to medical diagnostic technology with which to diagnose both communicable and non-communicable diseases will mean that many of these people will die of easily treatable conditions. Small, por
ABSTRACT Calcareous sandy grasslands are among the most threatened habitats in Europe, primarily because of abandonment, acidification, eutrophication and fragmentation. Much of the biodiversity found in calcareous sandy grasslands depend on the availability of calcareous sand in the topsoil layer. As this sand is naturally depleted of CaCO3 heavy disturbances such as erosion or use of military
Älvar och vattendrag i Västra Sverige utsätts för konstant erosion när ytvattnet från sjöar och mark tappas ut i havet. Den geologiska sammansättningen i älvarna under högsta kustlinjen består av glaciala och postglaciala finkorniga sediment som är avsatta i marin miljö. De känsliga lerlagrens struktur har efter urlakning blivit mer instabila och vid störning kan utlösa skred. Effekten av klimatfö
In recent years radical right parties have gained electoral strength across Europe, while the vote share of social democratic parties has declined. Using regional data and two fixed effect models this study investigates the impact of manufacturing employment and a range of other economic and demographic variables on the vote share of these parties in both national and European parliament elections
Lagrådet har en central roll i att granska nya lagförslag från riksdagen och regeringen. Denna granskning går främst ut på att säkerställa så att lagarna är lättförståeliga och förenliga med redan rådande lagstiftning. Under senare tid har allt större vikt från Lagrådets sida lagts på att kontrollera att nya lagförslag inte inskränker enskildas grundlagsskyddade fri- och rättigheter samt att de st
Enligt Trafikverkets siffror ökade utsläppen av växthusgaser från transportsektorn med 0,5 % under 2018 samtidigt som de måste minska med 8 för att nå de uppsatta målen. Ökningen berodde främst på en ökad lastbilstrafik. Det krävs flera lösningar för att nå detta mål. Detta arbete har undersökt om batterielektriska lastbilar kan vara en god lösning för emissionsfria transporter redan idag inom vis
The purpose of this essay is to show how the Vinnova financed pilot project Internet of Things (IoT) can be regarded as an expression of the marketing of places as a management of control measure. The so-called Place marketing is a theory referring to the development of brands and identities in geographic regions as an instrument for political orientation as well as a transitional process. The stu
