  1. 11. Cytokine responses in metal-induced allergic contact dermatitis : Relationship to in vivo responses and implication for in vitro diagnosis

    Författare :Jacob Minang; Marita Troye-Blomberg; Niklas Ahlborg; Rik Scheper; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metal allergy; Contact dermatitis; cytokines; ELISA; ELISpot; Flow cytometry; Immunology; Immunologi;

    Sammanfattning : Transition metals such as nickel (Ni), cobalt (Co), palladium (Pd), chromium (Cr) and gold (Au) are widely used as alloys in jewelry and biomaterials such as orthodontic and orthopaedic appliances. These metals also cause cell-mediated allergic contact dermatitis (ACD) reactions in a significant proportion of the population upon prolonged direct exposure. LÄS MER

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electromagnetic fields; exposure assessment; magnetic resonance imaging; switched gradient fields; radiofrequency fields; exposure metrics; radiofysik; radiation physics;

    Sammanfattning : Magnetic resonance imaging (MRI) has become one of the most common imaging modalities available in modern medicine, and it is an indispensable diagnostic tool thanks to the unparalleled soft-tissue contrast and high image resolution. It is also a unique exposure environment consisting of a complex mix of magnetic fields. LÄS MER

  5. 14. Toll-like receptors in airway inflammation in vitro and in vivo

    Författare :Ida von Schéele; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : During evolution a variety of solutions has been developed by different living organisms in order to protect itself from invading potential pathogens and particles. Protection of the host is essential for its survival and involves efficient recognition and elimination of potential pathogens. LÄS MER

  7. 15. Urinary tract infections in pregnancy : studies in vivo and in vitro

    Författare :Musa Sekikubo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The risk of urinary tract infection (UTI) in pregnant women is increased and predisposes them to acute pyelonephritis together with poor pregnancy outcomes. Increased frequency of micturition, nocturia and lower abdominal discomfort are common non-specific complaints during pregnancy, which render clinical diagnosis of UTI inaccurate. LÄS MER
