  1. 1. DNA fragmentation in cultured cells exposed to high linear energy transfer radiation

    Författare :Erik Höglund; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Onkologi; Oncology; Onkologi; Biomedical Radiation Science; biomedicinsk strålningsvetenskap;

    Sammanfattning : The DNA double-strand break (DSB) is a critical lesion which, if not completely restored, can have serious biological consequences. The relative biological effectiveness (RBE) of many severe end-points are closely related to radiation quality, with increased effectiveness at elevated ionization density. LÄS MER

  4. 3. Neuroendocrinology of agonostic interaction and social signalling in Artic charr (Salvelinus alpinus) : Studies on the neuroendocrine regulation of aggressive behaviour, stress responses and skin colour

    Författare :Erik Höglund; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Brain monoamines; social signalling; POMC; skin colour; stress; Salmonid; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; limnologi; Limnology;

    Sammanfattning : This thesis shows that socially subordinate Arctic charr (Salvelinus alpinus) display elevated brain serotonergic (5-HT) and norepinephric activity along with a chronic activation of the hypothalamic-pituitary-interrenal (HPI) axis, including elevated plasma concentrations of á-MSH. Furthermore, subordinate fish showed an inhibition of aggressive behaviour and darker body coloration, skin darkness being positively correlated with plasma á-MSH. LÄS MER

  5. 4. Non-conveyance within the Swedish ambulance service : A prehospital patient safety study

    Författare :Erik Höglund; Agneta Schröder; Emma Ohlsson-Nevo; Margareta Möller; Magnus Andersson-Hagiwara; Eric Carlström; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ambulance; Ambulance nurse; Ambulance service; Emergency medical services; Non-conveyance; Non‐transport; Nurse; Patient; Patient assessment; Patient-safety;

    Sammanfattning : BackgroundThere is an increasing demand for ambulance services and more patients than before are requesting ambulance assistance for low acuity conditions. Ambulance services non-convey patients because they lack acute care needs. LÄS MER

  7. 5. Genetic and Ecological Consequences of Fish Releases : With Focus on Supportive Breeding of Brown Trout Salmo trutta and Translocation of European Eel Anguilla anguilla

    Författare :Johan Dannewitz; Jacob Höglund; Erik Petersson; Ian Fleming; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; conservation; fishery management; panmixia; genetic variation; effective population size; hatchery selection; Biologi; Biology; Biologi;

    Sammanfattning : Although the practice of releasing fish into the wild is common in the management and conservation of fish populations, the success of release programmes and the potential harmful genetic and ecological effects that may follow are rarely considered. This thesis focuses on genetic and ecological consequences of fish releases, exemplified by supportive breeding of brown trout (Salmo trutta) and translocation of European eel (Anguilla anguilla).
