  1. 1. Experimental Injury to the Visual System : Molecular Studies of the Retina

    Författare :Ulrika Lönngren; Finn Hallböök; Fredrik Ghosh; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; retina; injury; ischemia; gene expression; brimonidine; alpha-2-adrenergic agonist; neuroprotection; growth factors; apoptosis; Müller cells; Neuroscience; Neurovetenskap;

    Sammanfattning : Retinal ganglion cells play a crucial role in the relay of visual signals from the eye to the brain. This cell type is affected and eventually lost in the eye disease glaucoma, resulting in progressive and irreversible loss of vision. LÄS MER

    Författare :Malin Åman; Karin Larsén; Magnus Forssblad; Jerker Sandelin; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; permanent medical impairment; severe injuries; knee injury; dental; eye injury; football; handball; ice hockey; floorball; basketball; motorcycle; automobile sports; incidence of acute injury; invaliditet; allvarliga skador; idrottsskada; försäkringsdata; knäskada; prevention; fotboll; innebandy; handboll; ishockey; basket; motorcykel; bilsport; tandskada; ögonskada; Medicin Teknik; Medicine Technology;

    Sammanfattning : Physical activity is an essential component of a healthy life, e.g. to prevent obesity, cardiovascular disease and premature death, of which sports can be an important part. Unfortunately, sports activities increase the risk of both overuse and acute injuries. LÄS MER

  4. 3. Vehicle-related injuries : with emphasis on fatality prevention

    Författare :Mats Öström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fatalities; injury; prevention; traffic; disease; alcohol; helmet; airbag;

    Sammanfattning : According to WHO, Sweden should aim to reduce unintentional fatalities, particularly vehicle-related injuries, by 25% by the year 2000. The aim of this thesis was to analyze vehicle-related injuries and injury events, especially the contributory effects of alcohol and disease and the injury reducing capacity of helmets and airbags in order to point out some preventive measures.

  5. 4. Clinical investigations of fixation stability and reading eye movements

    Författare :Fredrik Källmark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Scanning Laser Ophthalmoscope SLO ; Tobii Eye-tracker; reading speed; reading eye movements; fixation; regression; saccades; AMD; Lucentis.;

    Sammanfattning : Reading and writing plays a fundamental role in our culture. Compared with, e.g. speech, written language has an immense impact as it offers the possibility to share information over unprecedented distance in time and space. LÄS MER

  7. 5. Modulation of retinal progenitors : A bird’s-eye view of retinal regeneration and disease

    Författare :Dardan Konjusha; Finn Hallböök; Rusty Lansford; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Developmental neurobiology; Retinoblastoma; MYCN; Cone photoreceptor; Nolz1; Endothelin; Müller cells;

    Sammanfattning : The cell populations of the retina and their intricate organization provide us with one of the most important senses – vision. All retinal cell populations are derived from a common progenitor pool as a result of tight regulation of proliferation, differentiation, dedifferentiation, and programmed cell death. LÄS MER
