    Sammanfattning : A balanced tear film is essential for a healthy ocular surface. Insufficient tear production may result in dry eye, a common disorder in the elderly population. Dry eye causes significant discomfort in the patients and may lead to visual impairment and ocular infections. LÄS MER

  5. 24. Design and engineering of human transferrin receptor 1 and its binding proteins

    Författare :Dick J. Sjöström; Sinisa Bjelic; John Löfblom; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transferrin receptor; Machupo virus; protein engineering; Rosetta; flow cytometry; directed evolution; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : The human transferrin receptor 1 (TfR) is central in maintaining adequate cellular iron levels with the iron carrier proteins transferrin (Tf) and ferritin (Ft). Known to bind TfR is also HFE, another iron regulatory protein, competing with Tf for receptor binding. LÄS MER

  7. 25. Advancing Upconversion Emissions for Biomedical Imaging

    Författare :Haichun Liu; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; upconverting nanoparticles; luminescence; fluorescence; inverse problem; biomedical optics; biomedical imaging; photon migration; upconversion; tomography; saturation; Fysicumarkivet A:2014:Liu;

    Sammanfattning : During the past decade, upconverting nanoparticles (UCNPs) doped with rare earth ions have become an important class of fluorescence contrast agents for molecular imaging, due to their unique properties. Their property of anti-Stokes luminescence, with both the excitation and emission wavelengths close to the optimal for biomedical imaging, has been extensively explored in various biomedical applications.
