  1. 6. Immunopathogenic mechanisms in primary Sjögren’s syndrome

    Författare :Albin Björk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Primary Sjögren’s syndrome is a systemic autoimmune disease primarily affecting salivary and lacrimal glands, but patients may also have other organ involvement. Development of Sjögren’s syndrome has been associated with genetic polymorphisms and aberrances in innate and adaptive immunity, which include abnormal B cell functions with autoantibody production, and increased activity of the interferon (IFN) system.

  3. 7. Learning from primary immunodeficiencies to treat cancer

    Författare :Mariana M S Oliveira; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The immune system is a fine-tuned network of cells, tissues, organs and biological processes working together in order to protect our body. Immunodeficiency disorders occur when the body’s immune system is reduced or absent and can be characterized as primary, if the cause of disease is genetic; or secondary, if the cause of disease are extrinsic factors.

  4. 8. Physical control of primary production in a sub-arctic reservoir

    Författare :Jörgen Sahlberg; Lars Rahm; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The first paper (Paper I) in this thesis treats autumn cooling in the Swedish lake Väsman. The water temperature is simulated using a one-dimensional lake model where the vertical mixing is calculated by a k - ɛ turbulence model. The heat exchange between the atmosphere and the lake is formulated in terms of heat fluxes. LÄS MER

  5. 9. Biophysical and Human Controls of Land Productivity under Global Change : Development and Demonstration of Parsimonious Modelling Techniques

    Författare :Florian Sallaba; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecosystem Modelling; Meta-modelling; Net Primary Production; Global Change; Model coupling;

    Sammanfattning : Net primary production (NPP) serves as an indicator for plant-based resources such as food, timber and biofuel for human appropriation. It is defined by the annual production of plant matter and is mainly controlled by climate and human activities. Climate change in combination with human activities is altering NPP. LÄS MER

  7. 10. Brain structure and function in primary adrenal insufficiency

    Författare :Annelies van't Westeinde; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Individuals with primary adrenal insufficiency (PAI), i.e., congenital adrenal hyperplasia (CAH) and autoimmune Addison’s disease (AAD), suffer from impaired production of the adrenal gland hormones cortisol and aldosterone, and in the case of AAD, also androgens. LÄS MER
