1. 1. Stress in chickens : Effects of domestication and early experience on behaviour and welfare

   Författare :Maria Ericsson; Per Jensen; Linda Keeling; Bjarne Braastad; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The domestication is the process where animals have adapted to human conditions. A prerequisite for domestication is tame behaviour towards humans and subsequently, selection for other desirable traits took place which led to changes in several behavioural and physiological parameters.

3. 2. The Stress Hypothesis : Implications for the induction of diabetes-related autoimmunity in children?

   Författare :Anneli Sepa; Ann Frodi; Johnny Ludvigsson; Gunilla Bohlin; Linköpings universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Psychological stress; parenting stress; attachment security; serious life events; children; attitudes; Type I diabetes; beta-cell autoantibodies; prediction; etiology; Medicine; Medicin;

   Sammanfattning : Background: Second to Finland, Sweden has the world’s highest incidence of type 1 diabetes. Experiences of serious life events have retrospectively been shown to constitute a risk factor for the development of this disease, probably via the biological stress response. LÄS MER

4. 3. Stress, Drugs and Neuroscience : Neurobiological Effects of Social Stressors and Drug Exposure in Young and Adolescent Rats

   Författare :Linnea Granholm; Ingrid Nylander; Erika Roman; Anne-Lie Svensson; Maria Ellgren; Annika Thorsell; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescence; alcohol exposure; amphetamine; beta-endorphin; dopamine; dynorphin; early life; endogenous opioids; enkephalin; gene expression; high-speed chronoamperometry; nociceptin orphanin FQ; radioimmunoassay; self-administration; social stress; voluntary alcohol intake; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : Experiences early in life or during adolescence modulate neuronal networks in the immature brain and consequently lay the foundation for future susceptibility or resilience towards psychiatric disorders. The objective in this thesis is to understand, in part, how the surrounding environment shapes the brain of a young individual. LÄS MER

5. 4. Early life experiences and alcohol use in youth : An emerging role of the Vesicular Glutamate Transporters

   Författare :Maria Vrettou; Erika Comasco; Ingrid Nylander; Kent W. Nilsson; Åsa Wallén-Mackenzie; Roberto Ciccocioppo; Uppsala universitet; []
   Nyckelord :alcohol; early-life stress; brain; early adulthood; expression; DNA methylation; glutamate; Vesicular Glutamate Transporters;

   Sammanfattning : Initiation of alcohol consumption usually takes place during adolescence, a period characterized by a plethora of physical and emotional changes. Towards early adulthood, hazardous drinking patterns can emerge and potentially lead to the development of Alcohol Use Disorder (AUD). LÄS MER

7. 5. Adolescent behavior : Links to early-life stress and alcohol in male and female rats

   Författare :Stina Lundberg; Erika Roman; Ingrid Nylander; Heidi MB Lesscher; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescence; alcohol exposure; behavior; corticosterone; dynorphin; early life; endogenous opioid peptides; Met-enkephalin-Arg6Phe7 MEAP ; individual differences; multivariate concentric square field MCSF ; phenotyping; radioimmunoassay; selective breeding for alcohol consumption; voluntary alcohol intake; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : Adolescence is an important developmental phase with large changes in behavior, physiology and neurobiology, which transform an individual from immature child to independent adult. Due to these changes, adolescence is a sensitive period for exposure to environmental factors such as stress and drug exposure; it is also a common age of onset for alcohol consumption as well as several psychiatric disorders.
