   Sammanfattning : Dopamine (DA) has been shown to act as an intrarenal natriuretic hormone and defects in the renal DA system have been associated with some forms of hypertension. How the DA activity is upregulated durin- increased sodium intake is, however, unknown. LÄS MER

4. 3. On the association between panic disorder and autonomic regulation – With special focus on the roles of respiration and on the catechol-O-methyltransferase gene

   Författare :Kristina Annerbrink; Göteborgs universitet; []
   Nyckelord :panic disorder; serotonin; respiration; polymorphism; COMT Val158Met; HCRTR2 G1246A; blood pressure; anthropometry;

   Sammanfattning : Background and aims: Panic disorder is a psychiatric disorder characterized by sudden attacks of intense anxiety. It displays a lot of features suggesting that it may be associated with an underlying aberration in the autonomic regulation of heart activity and respiration: i) the attacks are often characterized by respiratory symptoms and symptoms from the heart, ii) the attacks can be elicited by respiratory stimulants, iii) between attacks, patients with panic disorder often display enhanced respiratory variability and reduced heart rate variability, and iv) patients with panic disorder display enhanced prevalence of respiratory disorders and enhanced mortality in cardiovascular disease.

5. 4. COMT Genotype, sex steroids, and bone phenotype in mice and men

   Författare :Anna-Lena Eriksson; Göteborgs universitet; []
   Nyckelord :estrogens; SNP; bone; fracture; growth;

   Sammanfattning : COMT GENOTYPE, SEX STEROIDS AND BONE PHENOTYPE IN MAN AND MICE Anna-Lena Eriksson Institute of Medicine, University of Gothenburg, Göteborg, Sweden, 2008 ABSTRACT Sex steroids are of profound importance for several physiological processes including reproduction, growth, and maintenance of skeletal integrity. Serum levels of sex steroids are associated with bone mineral density (BMD) and have been shown to be predictive of fracture risk in older people. LÄS MER

7. 5. The emotional motor system and gastrointestinal symptoms

   Sammanfattning : There is a significant comorbidity between anxiety/depression and functional gastrointestinal syndromes, such as irritable bowel syndrome (IBS) and functional dyspepsia. The pathophysiological link between emotions and the gut is not known. LÄS MER
