  1. 1. The Renin Angiotensin System in the Human Esophageal Mucosa − expression, actions and potential involvement in reflux disease

    Författare :Eleonora Björkman; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endoscopic biopsies; epithelial electrical current; epithelial electrical resistance; esophageal mucosae; gastroesophageal reflux disease; mucosal barrier integrity; renin angiotensin system;

    Sammanfattning : The renin angiotensin system (RAS) is a classical endocrine system, regulating body fluid balance and blood circulation. Recent research has shown that the system is being also locally expressed and active in several organs and tissues. LÄS MER

  2. 2. Methods for measurement of vocal fold vibration and viscoelasticity

    Författare :Hans Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; High-speed video imaging; kymography; acoustic analysis; vocal fold vibration; glottal edge; glottal area; laser; mucosal wave; triangulation; vocal fold; vocal fold length; vocal fold width; vocal fold strain; non-invasive; vocal fold scarring; air pulse stimulation;

    Sammanfattning : The overall aim of the thesis was to develop new methods for analysis of vocal fold vibrations and viscoelasticity and to test them in human subjects. In Study I the onset of vibration and irregular vocal fold vibration was examined with laryngoscopy using a high-speed camera at a frame rate of about 2000 images/sec. LÄS MER
