  1. 1. Experimental Vitreous Substitution

    Författare :Henrik Barth; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinal Detachment; Vitreous Body : surgery; Retina cytology metabolism surgery; Retina: Function; Retina: Inflammation; Retinal Detachment; Vitreous Body : surgery; Vitreous substitute; Vitrectomy;

    Sammanfattning : Blindness and visual disability are common following vitreoretinal pathologies such as open globe injury, proliferative diabetic retinopathy, and rhegmatogenous retinal detachment (RRD). These conditions often necessitate surgical intervention using vitrectomy with a tamponading vitreous substitute. LÄS MER

  3. 2. Postmortem analyses of vitreous fluid

    Författare :Brita Zilg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The identification of various various medical conditions postmortem is often difficult. Results from analysis of postmortem blood and urine samples are not as appropriate as in living subjects, due to bacterial contamination and postmortem cell degradation. LÄS MER

  4. 3. On Complications to Cataract Surgery

    Författare :Gunnar Jakobsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cataract surgery; pseudophakia; capsular rupture; retinal detachment; IOL dislocation; glaucoma; vitreous; immune mediators; immunoassay; cytokines;

    Sammanfattning : Cataract surgery, meaning exchange of the opaque lens in the eye with an artificial lens, is nowadays one of the most successful surgical procedures ever known. It is also the most frequent surgery performed in the Western world. In Sweden alone, more than 100,000 cataract operations are performed annually. LÄS MER

  5. 4. Intraocular Microdialysis

    Författare :Janina Waga; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; pharmacokinetics; drug adminstration; vitreous body; Microdialysis; eye; Oftalmologi;

    Sammanfattning : The method of microdialysis has been adapted for ocular use. It is a technique for monitoring concentrations of different molecules in a tissue in vivo. It is based on the principle of diffusion through a semipermeable membrane. The membrane is mounted on a soft plastic shaft, connected to an inlet and an outlet tube. LÄS MER

  7. 5. Transport in Oxides Studied by Gas Phase Analysis

    Författare :Qian Dong; Gunnar Hultquist; W.J. Quadakkers; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas Phase Analysis; metal; oxide; platinum; vitreous silica; yttria stabilized zirconia; diatomic gas; oxidation; dissociation; permeation; uptake release.; Chemical engineering; Kemiteknik;

    Sammanfattning : The transport in oxides is studied by the use of gas phase analysis (GPA). An experimental method to identify transported species of gases and their contribution to the overall transport of gases in oxides and an experimental method to evaluate the parameters diffusivity, concentration, permeability of gases in oxides and effective pore size in oxides are developed, respectively.
