  1. 1. Ultraviolet radiation cataract

    Författare :Konstantin Galichanin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :lens;

    Sammanfattning : Cataract is the leading cause of blindness in the world. Epidemiological and experimental evidence supports a link between mid-range ultraviolet radiation (UVR-B) exposure and the development of cataract. LÄS MER

  3. 2. Cataract from ultraviolet radiation

    Författare :Stefan Löfgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cataract; ultraviolet radiation; lens; rat; transmittance; pigment; age; pupil size.;

    Sammanfattning : Cataract is the major cause of low vision and blindness in the world. Epidemiological and experimental studies link cataract to (solar) ultraviolet radiation (UVR) exposure. Current safety limits of UVR exposure are based on animal experiments, but many factors are less well known in UVR cataractogenesis. LÄS MER

  4. 3. Ultraviolet radiation and cornea

    Författare :Alexander Podskochy; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cornea; UVR; keratocytes; apoptosis; Fas ligand; hyaluronan; biglycan; rabbit; wound healing.;

    Sammanfattning : Background: Acute exposure of the mammalian eye to UVR results in development of photokeratitis after a period of a few hours. Chronic exposure to UVR is associated with an increased risk of several corneal disorders, including pterygium, climatic droplet keratopathy, and climatic proteoglycan stromal keratopathy. LÄS MER

  5. 4. Multiparametric MRI for evaluation of tumour treatment response : Studies of 177Lu-octreotate therapy of neuroendocrine tumour

    Författare :Mikael Montelius; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; Functional imaging; IVIM; MRI; DWI; DCE; histology; 177Lu-octreotate; small intestine neuroendocrine tumour; NET; diffusion; perfusion; semi-quantitative; proteomics; ionizing radiation; biology; imaging biomarker;

    Sammanfattning : Clinical assessment of tumour response to treatment largely relies on estimates of tumour size by, e.g., measuring the largest tumour diameters on magnetic resonance (MR) or computed tomography (CT) images, weeks or months after treatment. LÄS MER

  7. 5. Radiation-induced vascular inflammation : translational studies

    Författare :Tinna Christersdottir Björklund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Radiotherapy has been shown to increase the risk for localized cardiovascular disease in a growing population of cancer survivors. However, irradiation, as a risk factor for vascular complications in free flap surgery, has been debated. LÄS MER
