    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

  3. 2. Autonomous cortisol secretion – Mortality, morbidity and diagnostics

    Författare :Albin Kjellbom; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenal incidentaloma AI ; Adrenal adenoma; Cortisol; autonomous cortisol secretion ACS ; Mortality;

    Sammanfattning : ContextUp to half of patients with adrenal adenomas found as incidentalomas show biochemical signs of subtle cortisol hypersecretion without having clinical signs or symptoms of Cushing’s syndrome. A condition called autonomous cortisol secretion (ACS). Previous studies have indicated that ACS might be associated with increased mortality. LÄS MER

  4. 3. ADHD and stress : Diurnal cortisol levels, early psychosocial adversity and perceived stress

    Författare :Johan Isaksson; Frank Lindblad; Kent W Nilsson; Per Gustafsson; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ADHD; HPA-axis; cortisol; hypocortisolism; diurnal rhythm; trauma; adversity; medication; perceived stress; gender differences; Child and Youth Psychiatry; Barn- och ungdomspsykiatri;

    Sammanfattning : The Hypothalamus-Pituitary-Adrenal axis (HPA-axis) with its end product cortisol mediates the physiological response to stress thereby promoting mobilization of energy. The cortisol levels follow a diurnal rhythm with a distinct awakening response. LÄS MER

  5. 4. Work stress and overtime work - effects on cortisol, sleep, sleepiness and health

    Författare :Anna Dahlgren; Torbjörn Åkerstedt; Göran Kecklund; Mikael Sallinen; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; work stress; overtime work; cortisol; sleep; sleepiness; fatigue; individual differences; within-subjects design; field study; Psychology; Psykologi;

    Sammanfattning : In Sweden the National Bureau of Statistics has reported an increase in stress-related disorders and sleep problems since the mid-1990’s. They also report that the number of hours of overtime worked has increased. LÄS MER

  7. 5. Irritable Bowel Syndrome : Diagnostic Symptom Criteria and Impact of Rectal Distensions on Cortisol and Electrodermal Activity

    Författare :Susanna Walter; Olof Hallböök; Göran Bodemar; Magnus Simrén; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Irritable Bowel Syndrome IBS ; diarrhoea- and constipation-predominant; stress; nervous; cortisol; Gastroenterology; Gastroenterologi;

    Sammanfattning : In a population prevalence questionnaire study we demonstrated that constipation and fecal incontinence are common problems in the general Swedish population with a similar magnitude as in other Western countries. 95.6% of the population had between three bowel movements per day and three per week.
