  1. 1. Non-enhanced single-energy computed tomography of urinary stones

    Författare :Johan Jendeberg; Mats Lidén; Per Thunberg; Anders Magnusson; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostic; CT; urinary stone; kidney stone; urolithiasis; phlebolith; uric acid; spontaneous passage; CNN; artificial intelligence;

    Sammanfattning : Computed tomography (CT) is the mainstay imaging method for urinary stones.The aim of this thesis was to optimize the information obtained from the initial CT scan to allow a well-founded diagnosis and prognosis, and to guide the clinician as early and as far as possible in the further treatment of urinary stone disease.

  3. 2. Dynamics of the Bacterial Genome : Rates and Mechanisms of Mutation

    Författare :Sanna Koskiniemi; Dan Andersson; Diarmaid Hughes; Ivan Matic; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteria; bacterial evolution; genome reduction; gene loss; serial passage; DNA homology; tranlesion DNA polymerase; stress; Microbiology; Mikrobiologi; Bacteriology; Bakteriologi; Evolutionary Genetics; Evolutionär genetik; Mikrobiologi; Microbiology;

    Sammanfattning : Bacterial chromosomes are highly dynamic, continuously changing with respect to gene content and size via a number of processes, including deletions that result in gene loss. How deletions form and at what rates has been the focus of this thesis. In paper II we investigated how chromosomal location affects chromosomal deletion rates in S. LÄS MER

  4. 3. Intestinal permeability : a parameter of mucosal dysfunction

    Författare :Pål Lundin; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Peptide; N-acetylcysteine; Medium-chain glyceride; Mannitol; Macromolecules; Lipid; Kinetics; In vivo; In vitro; In situ; Intestine; Injury; Inflammation; HLA-B27; HCl; Epithelium; Enhancer; dDAVP; 51Cr-EDTA; BSA; Absorption; Albumin; Permeability; Animal physiology; Djurfysiologi;

    Sammanfattning : The gastrointestinal tract has two opposing functions; to absorb nutrients and electrolytes, and to act as a barrier towards hazardous and non-nutritional substances. In the present thesis the barrier function of the gastrointestinal tract was studied in animal models in vivo, in situ and in vitro. LÄS MER

  5. 4. The stack mode review of volumetric datasets : applications for urinary stone disease

    Författare :Mats Lidén; Håkan Geijer; Torbjörn Andersson; Anders Magnusson; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stack mode display; image visualization; image perception; computed tomography; urinary stones; urolithiasis; PACS; Medicine; Medicin;

    Sammanfattning : During the last decades the acquisition and visualization of radiological images have rapidly evolved. The increasing amounts of volumetric image data particularly from modern CT systems necessitate a constant evolution of the radiological visualization techniques. LÄS MER

  7. 5. Airway protection and coordination of breathing and swallowing : in health and anesthesia

    Författare :Anna I. Hårdemark Cedborg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :pharynx;

    Sammanfattning : Swallowing and breathing is coordinated to ensure that the airway is protected from aspiration. During the pharyngeal phase of swallowing, breathing is interrupted to allow safe passage of bolus. However, details on the complex coordination of breathing and swallowing and their precise temporal relationship are not fully understood. LÄS MER
