  1. 1. Jejunoileal bypass for morbid obesity : studies of the long-term effects

    Författare :Anders Sylvan; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Jejunoileal bypass; Obesity; Surgery; Liver biopsy; Fibrinolytic system; Colonoscopy; Flow cytometry; Cancer risk;

    Sammanfattning : This study was aimed at investigating adverse and beneficial long-term effects of jejunoileal bypass (JIB) sugery in obese patients. The JIB was the first widly used surgical procedure for treatment of morbid obesity. The weight loss was remarkable, but the procedure was declared not appropiate for obesity surgery in the late 1970's. LÄS MER

  3. 2. Numerical studies of spin chains and cold atoms in optical lattices

    Författare :Sara Bergkvist Sylvan; Anders Rosengren; Richard Scalettar; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Teoretisk Fysik; Kondenserade materiens teori; Condensed matter physics; Kondenserade materiens fysik;

    Sammanfattning : An important, but also difficult, research field in condensed matter physics is that of strongly correlated systems. This thesis considers two topics in this field. The first topic is disorder and frustration in spin models. The introduction of disorder into quantum spin chains creates a complex problem. LÄS MER

  4. 3. Trauma - logistics and stress response

    Författare :Camilla Brorsson; Silvana Naredi; Anders Sylvan; Per Dahlqvist; Mikael Bodelsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; multiple trauma; hydrocortisone; adrenal insufficiency; hypnotics and sedatives; citric acid; glycerol; saliva; liver; colorectal surgery;

    Sammanfattning : Background: Trauma is a major cause of death and disability. Adverse events, such as prolonged prehospital time, hypoxia, hypotension and/or hyperventilation have been reported to correlate to poor outcome.Adequate cortisol levels are essential for survival after major trauma.
