  1. 26. Regional oxygenation in cardiac surgery. Influence of temperature, pump flow and insulin

    Författare :Lena Lindholm; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiopulmonary bypass; cardiac surgery; regional oxygenation; venous oxygenation; splanchnic oxygenation; insulin; vasodilation; temperature; pump flow;

    Sammanfattning : Surgical trauma triggers neural, endocrine and inflammatory reactions with subsequent alterations in systemic and regional blood flow, blood pressure and metabolism. These changes are detectable after all major surgical procedures but are often more pronounced after cardiac surgery, probably because of blood exposure to artificial surfaces of the heart lung machine, temperature modulation (e.

  3. 27. Stress system function in abdominal obesity. The hypothalamic-pituitary-adrenal axis and the sympathetic nervous system in middle-aged men

    Författare :Thomas Ljung; Göteborgs universitet; []
    Nyckelord :Abdominal obesity; stress; HPA axis; cortisol; glucocorticoid receptors; sympathetic nervous system; catecholamines; depression; SSRI;

    Sammanfattning : Background: There is a strong relationship between central (abdominal, visceral) obesity, impaired glucose tolerance, insulin resistance, dyslipidemia and elevated blood pressure. These abnormalities are included in the term Metabolic Syndrome, and indicate an elevated risk for cardiovascular disease and diabetes type 2. LÄS MER

  4. 28. On ischemia/reperfusion injury and rejection in concordant xenotransplantation to the rat

    Författare :Daniel Jan Lukes; Göteborgs universitet; []
    Nyckelord :Concordant; xenotransplantation; rat; hamster; mouse; rejection; necrosis; PCr; ß-ATP; ROS; SOE light; I RP; IPC;

    Sammanfattning : Studies in concordant (without preformed antibodies) rodent xenotransplantation (transplantation between species) models have focused, to date, on immunological disparities. In allotransplantation (transplantation within species), there is evidence suggesting that early ischemic events may contribute to later rejection episodes and to the development of chronicrejection features.

  5. 29. Lipoprotein(a) in cardiovascular disease

    Författare :Ulf Lundstam; Göteborgs universitet; []
    Nyckelord :atherosclerosis; Lipoprotein a ; LDL; extracellular matrix; women;

    Sammanfattning : The atherosclerotic process is continuous and starts early in life. Risk factors for atherosclerosis include hyperlipidemia, hypertension, smoking and diabetes mellitus. Fatty streaks characterised by lipid-laden macrophages are early signs of atherosclerosis. LÄS MER

  7. 30. Assessment of venous insufficiency in patients with chronic venous leg ulcers.Venous hemodynamics before and after surgery

    Författare :Marie Magnusson; Göteborgs universitet; []
    Nyckelord :Colour Doppler Ultrasound; leg ulcer; varicose vein surgery; recurrent leg ulcers;

    Sammanfattning : Venous insufficiency in the legs is a common disease, which may be complicated by chronic leg ulcers in 1% among the population. Venous ulcer duration is often long compared to other aetiologies and for the patient it involves long periods of pain, discomfort and reduced quality of life. LÄS MER
