Odour-mediated nectar foraging in the silver Y moth, Autographa gamma
It is well established that floral odours play a significant role in the nectar foraging behaviour in Lepidoptera and other insect orders. Floral odour may elicit searching, alighting and feeding behaviours alone or in concert with visual stimuli. The goal of the present project was to investigate attractiveness of different species of flowers to the silver Y moth, to identify constituents of vola
Isolation of caveolae using affinity two-phase partitioning
Popular Abstract in Swedish Målsättningen för detta arbete var att isolera caveolae för att kunna studera deras struktur och funktion. Caveolae är omegaformade inbuktningar i cellmembranet, ungefär 50-150 nm i diameter. Caveolae finns i många typer of celler, men inte i röda och vita blodkroppar eller nervceller. Man tror att de har flera viktiga funktioner. Exempelvis kan caveolae transportera moThe intention of this work was to establish alternative purification methods to obtain highly purified caveolae from various tissues. In order to isolate caveolae, sufficiently pure plasma membranes are needed. A method is presented for the isolation of plasma membranes from lung tissue using a combination of conventional polyethylene glycol/dextran two-phase partitioning and affinity partitioning

Physical activity and regional bone mass
Popular Abstract in Swedish Under de senaste decennierna har osteoporos (benskörhet) erhållit allt större uppmärksamhet eftersom allt fler individer drabbas av åkomman. Osteoporos är en sjukdom som ökar med stigande ålder och framför allt drabbar kvinnor. Sjukdomen leder till ökad risk för fraktur (benbrott) och antalet osteoporosrelaterade frakturer har ökat markant under senaste halvan av 1900-tThis thesis considers the effect of physical activity on bone mass in weight-loaded and unloaded regions of the skeleton. Bone mass was measured by Dual X-ray Absorptiometry (DXA) and by Quantitative Ultrasound (QUS). In a cross-sectional study 67 male soccer-players, on different levels of the Swedish national league, were compared with 24 male controls. No differences were demonstrated between s

Magnetic relaxation studies of self-associating and membrane proteins
Popular Abstract in Swedish Kärnmagnetisk resonans (NMR) har använts för att studera proteiner i vattenlösning. Metoden studerar hur signalen från vatten återgår till jämvikt efter att ha störts från jämvikt med antingen en radiofrekvent puls eller genom en kraftig ändring av magnetfält. Återgången kallas på fackspråk för relaxation och hänger samman med molekylernas rörelse. Kopplingen till molekMagnetic relaxation dispersion measurements have been performed on aqueous protein solutions to study the dynamics of waters in the proton transport channel of bacteriorhodopsin and the self-association of the proteins BPTI, lysozyme and beta-lactoglobulin. The measurements have focused on the bulk relaxation rates, R1 and R2, of three water nuclei 1H, 2H and 17O that are coupled to the protein en
Development and Characterisation of a Laser-Based Hard X-Ray Source
Popular Abstract in Swedish I denna avhandling presenteras en ny typ av röntgenkälla baserad på ett laser-producerat plasma. Röntgenstrålning alstras genom att fokusera laserpulser på ett strålmål. Energin i de enskilda laserpulserna blott är cirka 150 mJ, men tack vare den extremt korta pulstiden 100 fs (10E-13 s), blir laserns toppeffekt mer än 1 TW (10E12 W). Den extremt intensiva laserstrålninA laser-produced plasma was generated by focusing 100 fs laser pulses, with an energy of 150 mJ, onto metal targets. The laser intensity was expected to reach 10E17 W/cm2. Radiation was emitted from the created plasma, with photon energies extending up to the MeV regime. The laser-based X-ray source was optimised, with the purpose of making it a realistic source of hard X-rays (>10 keV). Dedicated
