1. 16. Cardiovascular effects of growth hormone. Studies in genetically engineered mice

   Författare :Irene Andersson; Göteborgs universitet; []
   Nyckelord :acromegaly; autonomic nervous system; cardiovascular disease; cardiac function; vascular function; growth hormone; heart rate variability; hypertension; insulin-like growth factor-1; transgenic mice;

   Sammanfattning : The general aim of this thesis was to enhance the understanding on the relationships between growth hormone (GH) and cardiovascular disease using genetically engineered mice. More specifically the effects of GH on blood pressure (BP), vascular and cardiac function, atherosclerosis and autonomic control of heart rate were studied. LÄS MER

3. 17. Heart Rate Variability in Stress-related Fatigue, Adolescent Anxiety and Depression and its Connection to Lifestyle

   Författare :Erik Olsson; Lennart Melin; Ulf Lundberg; Uppsala universitet; []
   Nyckelord :heart rate variability; autonomic nervous system; vagal tone; allostatic load; stress; fatigue; anxiety; depression; continuous performance; attention; cardiovascular risk; lifestyle; physical activity;

   Sammanfattning : Heart rate varies constantly as a consequence of activity in the sympathetic and parasympathetic autonomic nervous systems (SNS and PNS). In short-term recordings, heart rate variability (HRV) is mostly related to the inhibitory activity of the vagal nerves, which are part of the PNS. LÄS MER

4. 18. Accidental hypothermia and local cold injury : physiological and epidemiological studies on risk

   Författare :Helge Brändström; Michael Haney; Urban Wiklund; Anders Eriksson; Karl-Axel Ängquist; Ola Winsö; Sigridur Kalman; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cold-related injuries; hypothermia; frostbite; cold adaptation; rewarming; autonomic nervous system; heart rate variability;

   Sammanfattning : Background: (Papers I and II) The objectives were to first determine incidence and contributing factors to cold-related injuries in northern Sweden, both those that led to hospitalization and those that led to fatality.  (Papers III and IV) A further aim was to assess post-cooling hand-rewarming responses and effects of training in a cold environment, both on fingertip rewarming and on function of the autonomic nervous system, to evaluate if there was adaptation related to prolonged occupational cold exposure.

5. 19. Hypertrophic cardiomyopathy in Northern Sweden : with special emphasis on molecular genetics

   Författare :Stellan Mörner; Åke Hjalmarson; Umeå universitet; []
   Nyckelord :Hypertrophic cardiomyopathy; genetics; autonomic nervous system; familial amyloid polyneuropathy; echocardiography; Epidemiology; epidemiologi;

   Sammanfattning : Hypertrophic cardiomyopathy (HCM) is a heterogeneous, often familial disease, characterized by cardiac hypertrophy, predominantly affecting the interventricular septum. To date, no study has systematically analysed the genetic and phenotypic aspects of the disease in a Swedish population. LÄS MER

7. 20. Adipose tissue as an active organ : blood flow regulation and tissue-specific glucocorticoid metabolism

   Författare :Jonas Andersson; Tommy Olsson; Stefan Söderberg; Sverker Jern; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 11β-hydroxysteroid dehydrogenase type 1; adipose tissue; autonomic nervous system; blood flow; cortisol; nitric oxide; weight loss.; medicin; Medicine;

   Sammanfattning : Background: Despite advances in the treatment of atherosclerosis, cardiovascular disease is the leading cause of death worldwide. With the population getting older and more obese, the burden of cardiovascular disease may further increase. LÄS MER
