  2. 1. Hyaluronan Based Biomaterials with Imaging Capacity for Tissue Engineering

    Author : Yu Zhang; Dmitri Ossipov; Carsten Werner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; hydrogel; scaffold; tissue engineering; imaging; interpenetrating network; MRI; fluorescence imaging; scaffold degradation;

    Abstract : This thesis presents the preparation of hyaluronan-based biomaterials with imaging capability and their application as scaffolds in tissue engineering. First, we have synthesized HA derivatives functionalized with different chemoselective groups. READ MORE

  4. 2. Imaging Living Cells with an X-ray Laser

    Author : Gijs van der Schot; Tomas Ekeberg; Janos Hajdu; Filipe Maia; Pierre Thibault; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Coherent diffractive X-ray imaging; flash X-ray imaging; lensless imaging; single particle imaging; cyanobacteria; phasing; image classification; substrate-free sample delivery; X-ray free-electron laser; XFEL; FEL; CDXI; CDI; CXI; FXI; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Abstract : Imaging living cells at a resolution higher than the resolution of optical microscopy is a significant challenge. Fluorescence microscopy can achieve a degree of super-resolution via labeling cellular components with a fluorescent dye. READ MORE

  5. 3. High-resolution imaging of kidney tissue samples

    Author : David Unnersjö-Jess; Hans Blom; Lena Scott; Hjalmar Brismar; Peter Hansell; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Super Resolution Microscopy; Kidney; Imaging; Fluorescence; Kidney development; Calcium; Biological Physics; Biologisk fysik;

    Abstract : The kidney is one of the most important and complex organs in the human body, filtering hundreds of litres of blood daily. Kidney disease is one of the fastest growing causes of death in the modern world, and this motivates extensive research for better understanding the function of the kidney in health and disease.

  6. 4. Optical spectroscopy and fluorescence imaging for cancer diagnostics

    Author : Pontus Svenmarker; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biomedical optics; Diffuse-reflection spectroscopy; Upconverting nanoparticles; Inverse problem; Fluorescence; Tomography; Imaging; Scattering media; Photon migration; Fysicumarkivet A:2012:Svenmarker;

    Abstract : This work presents optical methods for diagnosing cancer. A complementary method for diagnosing eye cancer was investigated using a technique developed within this work named transscleral optical spectroscopy (TOS). READ MORE

  7. 5. Theranostics in Neuroendocrine Tumors : Somatostatin Receptor Imaging and Therapy

    Author : Ezgi Ilan; Mark Lubberink; Peter Bernhardt; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 177Lu-DOTATATE; 68Ga-DOTATATE; 68Ga-DOTATOC; PRRT; Theranostics; PET CT; SPECT CT; Neuroendocrine tumors; Somatostatin receptors; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : Neuroendocrine tumors (NETs) are characterized by cellular overexpression of somatostatin receptors (SSTR), which allows for the use of radiolabeled somatostatin analogs (SSA) for both imaging and therapy. Because NETs often are diagnosed at a metastatic stage, curative surgery is not possible. READ MORE
