  3. 7. Partnership Relation Quality modulates the effects of Work-stress on health

    Författare :Ann-Christine Andersson Arntén; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; work-related stress; partnership relation; health; stress; positive affect; negative affect;

    Sammanfattning : The present studies included 884 participants in total, in five different studies referred to in the four articles. All five studies observed participants from different types of occupation in order to obtain a distribution and a diversified group of individuals. LÄS MER

  4. 8. The conserved methionines in the chloroplast small heat shock protein - Role in chaperone-substrate interactions and effects of methionine sulfoxidation on chaperone activity

    Författare :Niklas Gustavsson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biochemistry; oxidative stress; thermostability; temperature stress; stress tolerance; sHsp; protein aggregation; molecular chaperone; Heat stress; methionine sulfoxidation; Biokemi; metabolism; Plant biochemistry; Växtbiokemi;

    Sammanfattning : The chloroplast-localized small heat shock protein (sHsp) Hsp21 belongs to the family of alpha-crystallin like sHsps which form large oligomeric structures and protect partly unfolded aggregation-prone proteins against aggregation. The main focus for this thesis has been on the highly conserved methionines in Hsp21. LÄS MER

    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

  7. 10. The effects of stress on atherosclerosis in mice

    Författare :Evelina Bernberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Psychosocial stress; Social isolation; Stressors; Social disruption stress; Atherosclerosis; Cytokines; Corticosterone; Metoprolol;

    Sammanfattning : Psychosocial stress has been recognized as an independent risk factor for cardiovascular disease and atherosclerosis. However, little is known about the mechanisms converting this psychosocial load into physical disease. LÄS MER
