  1. 16. Mosses as mediators of climate change : implications for tree seedling establishment in the tundra

    Författare :Signe Lett; Ellen Dorrepaal; David Wardle; Marie-Charlotte Nilsson; Vigdis Vandvik; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; arctic; alpine; B. pubescens; bryophytes; competition; facilitation; mosses; P. sylvestris; precipitation changes; seedlings; traits; tree line; warming;

    Sammanfattning : Alpine and arctic tree line expansion depends on the establishment of tree seedlings above the current tree line, which is expected to occur with climate warming. However, tree lines often fail to respond to higher temperatures. Other environmental factors are therefore likely important for tree seedling establishment. LÄS MER

  3. 17. Effects of inflammatory mediators on human osteoblasts

    Författare :Anders Frost; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

    Sammanfattning : Inflammatory mediators produced in or adjacent to bone have implications on bone and may induce both osteolysis and/or osteosclerosis. Inflammatory cytokines mediate these effects by acting either directly or indirectly on the bone cells. LÄS MER

  4. 18. Intrafollicular pressure and biochemical mediators in ovulation

    Författare :Markus Matousek; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ovulation; protein tyrosine kinase; ovulation; leukotriene B4; intrafollicular pressure; contractions and smooth muscle cell.;

    Sammanfattning : Ovulation is the process whereby the preovulatory follicle ruptures to enable a fertilisable ovum to escape from the interior of the ovary to the oviduct. During the ovulatory process, from he onset of the preovulatory LH-surge to the follicular rupture, marked biochemical and structural changes in follicles to enable it to rupture. LÄS MER

  5. 19. Effects of Inflammatory Mediators on Pulmonary Airways

    Författare :Ofir Bachar; Klinisk och experimentell allergiforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electric ?eld stimulation; bradykinin; airway; tumor necrosis factor a; Respiratory system; nitric oxide; Andningsorganen; Toll-like receptor; prostaglandin E2; neurotrophin; allergy;

    Sammanfattning : Chronic inflammation is together with excessive contraction of the airways key features of asthma. The aims of the thesis were to analyze the effect of inflammatory mediators on airway smooth muscle, using an in vitro model of cultured murine airways. LÄS MER

  7. 20. Identification of galectins as novel inflammatory mediators

    Författare :Jenny Almkvist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human neutrophils; NADPH-oxidase; Galectin-1; Galectin-3; priming; degranulation;

    Sammanfattning : The human neutrophils play important roles in the host defence against invading microorganisms. To eliminate bacteria or other invaders the neutrophils have to leave the bloodstream and cross the endothelium, migrate through the extracellular matrix towards the site of infection and phagocytose the prey to ultimately kill it.
