  1. 1. Vitamin D status in psoriasis patients treated with UVB therapy

    Författare :Amra Osmancevic; Göteborgs universitet; []
    Nyckelord :Vitamin D; PTH; psoriasis; bone mineral density; ultraviolet UVB;

    Sammanfattning : Vitamin D status in psoriasis patients treated with UVB therapy Amra Osmancevic Department of Dermatology and Venereology, Institute of Clinical Sciences at Sahlgrenska Academy, University of Gothenburg, Göteborg, Sweden Abstract The thesis deals with the effect of ultraviolet B (UVB) 280-320 nm on vitamin D production in psoriasis patients during treatment with phototherapy. Background: Psoriasis is a chronic, inflammatory disease affecting the skin and potentially the joints. LÄS MER

  3. 2. Studies related to bone mass in patients with cystic fibrosis

    Författare :Eva Gronowitz; Göteborgs universitet; []
    Nyckelord :DXA; infection; lung function; parathyroid hormone; physical activity; vitamin D; ; pQCT; UVB;

    Sammanfattning : Cystic fibrosis is the most common genetic disease that causes respiratory failure and earlydeath. The lifespan of these patients has gradually increased due to improved generaltreatment, but concurrent with this, new complications have emerged, and changes in bonemineral density (BMD) have been stressed as a major problem.

  4. 3. Thin-film ultraviolet light-emitting diodes realized by electrochemical etching of AlGaN

    Författare :Michael Alexander Bergmann; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thin-film flip-chip; light-emitting diodes; UVB; AlGaN; thermocompression bonding; substrate removal; ultraviolet light; electrochemical etching; heterogeneous integration; LEDs;

    Sammanfattning : Ultraviolet (UV) light sources have a direct impact on everyone’s life. They are used to sterilize surfaces as well as for water purification. In addition, they are used in green houses to enhance health-promoting substances in plants, for phototherapy to treat skin diseases, for sensing and material curing. LÄS MER

  5. 4. Future stratospheric ozone depletion will affect a subarctic dwarf shrub ecosystem

    Författare :Ulf Johanson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vaccinium; UVB; subarctic; shoot growth; ozone depletion; leaf thickness; irradiation system; heath ecosystem; Empetrum; dwarf shrubs; Calamagrostis; decomposition; Physiological biophysics; Växtfysiologi;

    Sammanfattning : The stratospheric ozone depletion and the concomitant increase in ultraviolet-B (UV-B, 280-320 nm) radiation is of global concern due to the effects of UV-B on living organisms. To investigate the effects of increased levels of UV-B, a field irradiation system was established at a subarctic dwarf shrub heath in Northern Sweden (68 °N). LÄS MER

  7. 5. Towards a Translational Pain Model - Techniques and developments

    Författare :Leila Etemadi; Neuronano Research Center (NRC); []
    Nyckelord :UVB irradiation; Pain; Neuropeptides; Inflammation; Contralateral; Lateral spinal nucleus; Micro-array electrodes; Pan-neuronal markers; immunohistochemistry;

    Sammanfattning : Pain is a major health issue for each affected individual and has a large impact on health costs. Most of our knowledge about this defensive system rely on data from different animal experiments. There is an obvious need for a translational pain model allowing comparisons between experimental animals and humans. LÄS MER
