  1. 1. Nutrient balance and salinity stress in arbuscular mycorrhizal fungi

    Författare :Edith Hammer; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inoculum; Glomalin; Fatty acids; Osmolyte; Organic matter; K; Na; Salinity; Symbiotic exchange; Phosphorus P; Carbon C; PIXE; Arbuscular mycorrhizal fungi; Rhizobium;

    Sammanfattning : Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. LÄS MER

  3. 2. Foreign molecules in biomembranes : Molecular effects on intact stratum corneum and model lipid systems

    Författare :Quoc Dat Pham; Fysikalisk kemi; []
    Nyckelord :stratum corneum; lipid; keratin filament; protein; DMPC; penetration enhancer; osmolyte; solvent; monoterpene; fatty acid; hydration; molecular mobility; fluidity; permeability; PT ssNMR; diffusion cell;

    Sammanfattning : This thesis mainly explores how the molecular mobility of lipid and protein components in the outermost layer of the skin, the stratum corneum (SC), varies with different conditions and upon adding foreign compounds. These studies require methods that makes it possible to detect and characterize the minor amount of fluid components in the highly ordered solid SC sample with resolved molecular information.

  4. 3. Methods for the Synthesis of PET Tracers and NMR Studies of Ribonuclease A

    Författare :Linda Samuelsson; Bengt Långström; Sharon Stone-Elander; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; [11C]methyl iodide; Stille reaction; palladium; Ribonuclease A; osmolytes; PFG-NMR; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis contains two parts.In the first part, general and versatile palladium-mediated 11C-C bond forming reactions for use in the production of radiotracers for Positron Emission Tomography (PET) were explored. LÄS MER

  5. 4. Preeclampsia and the Brain : Epidemiological and Magnetic Resonance Studies

    Författare :Maria Nelander; Johan Wikström; Anna-Karin Wikström; Inger Sundström Poromaa; Gerda Zeeman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preeclampsia; eclampsia; seizure; MRI; MRS; IVIM; dementia; cardiovascular disease; magnesium; cerebral organic osmolytes; perfusion; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Preeclampsia is a pregnancy specific syndrome that causes substantial maternal and fetal morbidity and mortality. One major contributor to maternal deaths is eclampsia, i.e. when seizures arise in the context of preeclampsia. LÄS MER

  7. 5. Establishing the mechanistic basis of sugar transport

    Författare :Abdul Aziz Qureshi; David Drew; Magnus Wolf-Watz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane transport; transport energetics; nucleotide-sugar transporters; glucose transporters; malaria; cancer; Biochemistry; biokemi;

    Sammanfattning : Sugar is a vital molecule required for cell viability and homeostasis. Sugar is important for metabolic energy, energy storage, signaling, structure and osmolyte regulation. Transport of sugar represents an important physiological process. LÄS MER
