  1. 11. Therapeutic aspects of oral and pharyngeal swallowing dysfunction. Videoradiographic and videomanometric analyses of adult healthy volunteers and dysphagic patients

    Författare :Margareta Bülow; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; tomography; radiology; Clinical physics; Therapy; Videoradiography; Videomanometry; Dysphagia; Dysfunction; Swallowing; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : In this study simultaneous videoradiography and intraluminal manometry (videomanometry) have been used in combination in three studies to analyze how different therapeutic strategies affect the physiology of swallowing in healthy volunteers and in patients with pharyngeal dysfunction. Analyses of healthy volunteers showed few significant measurable effects on the pharyngeal swallow. LÄS MER

  3. 12. Experimental studies of the regulations of synthesis and release of tissue-type plasminogen activator from vascular endothelium

    Författare :Lena Selin Sjögren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tissue-type plasminogen activator; endothelium; fluid mechanical forces; shear stress; pressure; immunohistochemistry; gene expression;

    Sammanfattning : The fibrinolytic system has several important functions and one crucial function is the prevention and removal of fibrin deposits in blood vessels. Tissue-type plasminogen activator (t-PA) plays a key role in this process, and in vitro data suggest that an acute release of t-PA is induced as a thromboprotective response whenever clotting mechanisms are initiated.

  4. 13. Assessment of tubal infertility with radionuclide-labelled particles and falloscopy

    Författare :Steffan Lundberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :fallopian tube; falloposcopy; hysterosalpingography; radionuclide hysteropingography; tubal infertility; tubal investigation; tubal transport;

    Sammanfattning : The fallopian tubes are of central importance for human reproduction in vivo. Damage to the tubal internal mucosa can result in disturbance of sperm and ovum transport. About 40% of infertile women have tubal disease as their main cause of infertility. LÄS MER

  5. 14. Local regulation of the endogenous fibrinolytic system in man

    Författare :Thordis Hrafnkelsdottir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tissue-type plasminogen activator; plasminogen activator inhibitor type-1; endothelium; extracellular nucleotides; hypertension; chronic renal failure;

    Sammanfattning : The physiologically most important activator of intravascular fibrinolysis is tissue-type plasminogen activator (tPA). The endothelium synthesises and stores tPA and regulated release of the enzyme is an important mechanism for removal of fibrin from blood vessels. Plasminogen activator inhibitor type-1 (PAI-1) is the main inhibitor of tPA. LÄS MER

  7. 15. Mechanisms of stretch-induced growth and contractile differentiation in vascular smooth muscle

    Författare :Asad Zeidan; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; SM22a; ERK1 2; caveolae; stretch; Smooth muscle; differentiation;

    Sammanfattning : Vascular smooth muscle can adapt to increased intraluminal pressure by remodelling and hypertrophy, as seen in hypertension. The molecular mechanisms responsible for this are still incompletely characterized. LÄS MER
