  1. 11. Myocardial infarction and cardiac regulation in relation to vibration exposure

    Författare :Bodil Björ; Per Gustavsson; Umeå universitet; []
    Nyckelord :vibration exposure; myocardial infarction; cardiac regulation; exposure assessment; occupational exposure; epidemiology; cohort study; case-control study; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : The purpose of this thesis was to assess the possible risk of myocardial infarction in work entailing exposure to vibration, and to study whether there is any relation between short-term exposure to vibration and cardiac regulation. Epidemiological methods were applied to investigate a possible association between occupational exposure to vibration and myocardial infarction. LÄS MER

  3. 12. On the Evolution of the Avian Transcriptome

    Författare :Severin Uebbing; Hans Ellegren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; evolution; gene expression; regulation; RNA-seq; transcriptomics; proteomics; sex chromosome; dosage compensation; divergence; ASE; birds; Ficedula; flycatcher; chicken; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Change in gene expression is a powerful tool for evolution, because seemingly small expression changes can contribute important steps towards adaptation without necessarily affecting the whole organism. There is still much to learn about how gene expression evolves on genome- and population-wide levels, especially in non-model organisms. LÄS MER

  4. 13. En dyster parentes – opiatregeln i svensk LARO-behandling 2010–2016

    Författare :Bodil Monwell; Arne Gerdner; Björn Johnson; Per Bülow; Thomas Clausen; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; opiates; opioids; opioid maintenance treatment; methadone; buprenorphine; regulation; National Board of Health and Welfare; opiater; opioider; opioidberoende; buprenorfin; metadon; läkemedelsassisterad behandling; föreskrift; Socialstyrelsen;

    Sammanfattning : Opioids are well documented to arouse euphoria, relieve pain, and to have a high dependency potential. Opioid dependence is a serious chronic condition with a high risk of extensive worsened health, relapse and premature death.Opioid maintenance treatment (OMT) is well researched and has strong scientific support.

  5. 14. Survival patterns and density-dependent processes in breeding mallards Anas platyrhynchos

    Författare :Gunnar Gunnarsson; Kjell Sjöberg; Johan Elmberg; Per Lundberg; Robert Clark; Högskolan Kristianstad; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; broods; dabbling ducks; density dependence; ducklings; experiments; models; mortality; nest predation; regulation; survival; Terrestrial ecology; Terrestrisk ekologi;

    Sammanfattning : Measuring and assessing vital rates such as births and deaths are prerequisites for understanding population dynamics. Vital rates may be affected by the density of individuals, even though the importance of density dependence on population dynamics has been debated for a long time. LÄS MER

  7. 15. Moments of meaning – Towards an assessment of protective and risk factors for existential vulnerability among young women with mental ill-health concerns : A mixed methods project in clinical psychology of religion and existential health

    Författare :Christina Lloyd; Valerie DeMarinis; Britt af Klinteberg; Wolfgang Rutz; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Clinical population; depression; anxiety; existential anxiety; internalized symptoms; crisis of meaning; inhibition of aggression; identity; meaning-making; emotion regulation; sense of coherence; self-concept; disruption and repair; high affective moments; existential worldview function; ontological security; belonging; loneliness; sacredness; death; Religionspsykologi; Psychology of Religion;

    Sammanfattning : The present sequential mixed-methods project was conducted in the area of clinical psychology of religion and existential health. The central aim of the project was to investigate clinically relevant areas for an assessment of protective and risk factors for existential vulnerability and dysfunctional existential meaning-making in a clinical sample of young women with mental ill-health concerns.
