    Sammanfattning : Postpartum depression is a psychiatric disorder affecting a substantial proportion of newly delivered women, and remains a significant cause of childbirth-related morbidity. The aim of the present thesis was to examine psychological, endocrine and genetic aspects of postpartum depression in a large, population-based sample of women in Uppsala, Sweden. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phenotypic plasticity; inducible defences; stress physiology; cortisol; immune function; trade-offs; sexual dimorphism; crucian carp; visual ecology; predator-prey interactions; POMC pro-opiomelanocortin ; colour change; eco-immunology; Anti-predator defences; Inducible morphological defence; Phenotypic plasticity; Stress physiology; Cortisol; Immune function; Crucian carp; Predator-prey interactions; Trade-offs; Sexual dimorphism; POMC; Pro-opiomelanocortin; Visual ecology; Eye evolution; Melanin; Eco-immunology; Pace-of-life; Behavioural plasticity;

    Sammanfattning : Almost all species face some degree of predation risk, and, hence, evolution has produced a plethora of anti-predator defences. However, anti-predator strategies require resources, and the prevailing risk of becoming prey is influenced by many factors and rarely constant across time and space. LÄS MER

  5. 4. Psycho-physiological reactions to violent video gaming : Experimental studies of heart rate variability, cortisol, sleep and emotional reactions in teenage boys

    Författare :Malena Ivarsson; Lennart Högman; Frank Lindblad; Staffan Janson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; video gaming; media violence; autonomic nervous system; heart rate variability; HPA axis; cortisol; sleep quality; emotional reactions; desensitization; teenagers; Psychology; psykologi;

    Sammanfattning : Playing violent video games may provoke aggression. Psycho-physiological methods may provide knowledge about the underlying psychological processes. Most previous studies have been performed in laboratory settings at daytime with adults. LÄS MER

  7. 5. 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
