  1. 1. Risk factors for development of neurocognitive disorders

    Detta är en avhandling från Lund University, Faculty of Medicine

    Författare :Anna-Märta Gustavsson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vascular risk factors; dementia; Alzheimer’s disease; ß-amyloid; white matter hyperintensities; cerebral small vessel disease;

    Sammanfattning : AbstractVascular risk factors are believed to be involved in dementia development by increasing risk of the most common dementia types, Alzheimer’s disease (AD) and vascular dementia. The aim of this thesis was to study if risk factorsaffect key brain pathology directly, by using biomarkers for dementia in preclinical stages, and to assess previous findings in a large population-based setting.

  2. 2. Effects of invasin and YopH of Yersinia pseudotuberculosis on host cell signaling

    Detta är en avhandling från Umeå : Molekylärbiologi (Teknisk-naturvetenskaplig fakultet)

    Författare :Anna Gustavsson; Umeå universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; β1-integrin; Yersinia pseudotuberculosis; Invasin; YopH; Cell-Matrix Adhesion; Filopodia; Cell Spreading; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Integrins are a large family of membrane-spanning heterodimeric (αβ) receptors that bind to ligands on other cells or to extracellular matrix (ECM) proteins. These receptors mediate bidirectional signaling over the cell membrane to induce signaling cascades mediating functions as cell adhesion, spreading and migration. LÄS MER

  3. 3. A mapping of the interactions between a moth sex pheromone component and its receptor

    Detta är en avhandling från Organic Chemistry, Lund University

    Författare :Anna-Lena Gustavsson; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; chiral recognition; bioactive conformation; structure-activity; Agrotis segetum; Z -5-decenyl acetate; pheromone analogues; single-cell electrophysiology; molecular mechanics; ab initio; MM3; quantum mechanical calculations; 3D-QSAR; bioisosteres; Organisk kemi;

    Sammanfattning : Popular Abstract in Swedish Insekter kommunicerar med dofter. De artspecifika kemiska substanser som används mellan individer kallas feromoner. Hos sädesbroddflyet, Agrotis segetum, producerar honan en "parfym", ett sexualferomon som består av flera komponenter, för att locka till sig en hane. LÄS MER

  4. 4. Glycolytic oscillations in individual yeast cells

    Detta är en avhandling från Organic Chemistry, Lund University

    Författare :Anna-Karin Gustavsson; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical manipulation; Microfluidics; Fluorescence microscopy; Single cell analysis; Saccharomyces cerevisiae; Glycolysis; Oscillations; NADH; Heterogeneity; Synchronization; Robustness; Universality;

    Sammanfattning : Oscillations in the concentration of yeast glycolytic intermediates have been intensively studied since the 1950s, but these studies have so far been limited to observations of average oscillatory behavior in synchronized cultures. Hence, it has remained unknown whether the onset of oscillations is a collective property of the population which requires a high cell density, or if individual cells can oscillate also in isolation.

  5. 5. Single Cell Studies of Glycolytic Oscillations Using Microfluidics and Optical Tweezers

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Anna-Karin Gustavsson; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Optical manipulation; microfluidics; fluorescence microscopy; single cell imaging; Saccharomyces cerevisiae; glycolysis; oscillations; NADH;

    Sammanfattning : The complex set of reactions in metabolism has been extensively studied in populations with millions of cells, but much information can still be gained by studying the heterogeneous metabolic behaviour in individual cells. The first part of energy metabolism is called glycolysis and is very similar in mammalian cells, such as human cells, and in yeast cells. LÄS MER
