   Sammanfattning : The aims of this thesis were to explore nurses' experiences of stress in the ICU (I), to analyze experiences of moral concerns in intensive care nursing from the perspective of relational ethics (II), to describe the synthesis of the concept of moral stress and to identify preconditions for moral stress (III) and to analyse and describe lived experiences of support in situations characterized by critical care situations and moral stress in intensive care (IV).The design was exploratory and descriptive.

3. 2. Roles of Arginine-Vasotocin and Corticotropin-Releasing Hormone in Stress Responses and Agonistic Behaviour of Rainbow Trout

   Författare :Tobias Backström; Svante Winberg; Lynne Sneddon; Uppsala universitet; []
   Nyckelord :Zoophysiology; arginine-vasotocin AVT ; corticotropin releasing hormone CRH ; stress; stress coping; behaviour; rainbow trout; Zoofysiologi;

   Sammanfattning : The neuropeptides arginine-vasotocin (AVT) and corticotropin-releasing hormone (CRH) are involved in the hypothalamic-pituitary-interrenal (HPI) axis. During stress, the HPI axis is activated and cortisol is released into the blood. In addition to their role in the HPI axis, AVT and CRH also have behavioural effects. LÄS MER

4. 3. Effect of Dietary Antioxidants on Oxidative Stress, Inflammation and Metabolic Factors : Studies in Subjects with Overweight and with Type 2 Diabetes

   Författare :Elisabet Rytter; Samar Basu; Bengt Vessby; Anders Sjödin; Helmut Sies; Uppsala universitet; []
   Nyckelord :Antioxidants; supplementation; fruit and vegetables; oxidative stress; isoprostanes; lipid peroxidation; oxidative damage to DNA; glycaemic control; inflammation; overweight; type 2 diabetes; MEDICINE; MEDICIN; Nutrition; Nutrition;

   Sammanfattning : Observational studies have indicated that fruit and vegetables, and dietary antioxidants may play an important role in reducing the risk of chronic diseases, potentially by affecting pathogenic mechanisms such as oxidative stress and inflammation. Clinical trials investigating the effects of supplementation with single or a few antioxidants in high doses have, however, shown inconsistent results and thus have not been able to support the observational findings.

5. 4. Abused Women : Health, Somatization, and Posttraumatic Stress

   Författare :Charlotta Samelius; Klaas Wijma; Barbro Wijma; Gun Wingren; Elisabet Sundbom; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Abuse; Prevalence; Psychological health; Somatization; Posttraumatic stress; Psychology; Psykologi;

   Sammanfattning : The aims of this thesis were to estimate the lifetime prevalence of physical, sexual, and psychological abuse in a random population-based sample of women aged 18-60 years; to estimate current suffering thereof; and to investigate associations between abuse and health problems, more specifically to study abuse related variables associated with somatization and PTSD, respectively.The studies had a cross-sectional design.

7. 5. Neuroendocrinology of agonostic interaction and social signalling in Artic charr (Salvelinus alpinus) : Studies on the neuroendocrine regulation of aggressive behaviour, stress responses and skin colour

   Författare :Erik Höglund; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Brain monoamines; social signalling; POMC; skin colour; stress; Salmonid; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; limnologi; Limnology;

   Sammanfattning : This thesis shows that socially subordinate Arctic charr (Salvelinus alpinus) display elevated brain serotonergic (5-HT) and norepinephric activity along with a chronic activation of the hypothalamic-pituitary-interrenal (HPI) axis, including elevated plasma concentrations of á-MSH. Furthermore, subordinate fish showed an inhibition of aggressive behaviour and darker body coloration, skin darkness being positively correlated with plasma á-MSH. LÄS MER
