1. 1. Light-Sheet Imaging of Collagen in Renal Tissue in Aqueous and Anhydrous Conditions

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Felicia Näsman; [2023]
   Nyckelord :Kidney disease; Renal fibrosis; Light-sheet Microscopy; Collagen; Fast Green; Kronisk njursjukdom; Njurfibros; ”Light sheet”-mikroskopi; Kollagen; Fast Green;

   Sammanfattning : Chronic kidney disease is a progressive kidney disease that affects approximately one tenth of the world population. In almost all cases of progressive, end-stage kidney disease, fibrosis is seen. Renal fibrosis is a condition of the kidneys in which collagens and other proteins accumulate in the extracellular matrix of the kidneys. LÄS MER

3. 2. Feedback imaging of cellular dynamics with fluorescence microscopy

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Emil Sorcini; [2022]
   Nyckelord :Tracking; Segmentation; Fluorescence microscopy; Lattice light-sheet; Cell migration; NK cells; ZEN; OAD; Experiment Feedback; Spårning; Segmentering; Fluorescensmikroskopi; Lattice light-sheet; Cellmigration; NK celler; ZEN; OAD; Experiment Feedback;

   Sammanfattning : In biology, it is common to study cultured cells (in vitro) with fluorescence time-lapse microscopy. The cells are recorded for longer period of time and can later be viewed at an accelerated speed. During the acquisition some live cells tend to migrate. LÄS MER

4. 3. The Influence of 3D Cell Organization in Tumor Spheroid on Natural Killer Cell Infiltration and Migration

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Luigi Morrone; [2020]
   Nyckelord :Natural Killer Cells; Tumor Spheroids; Fluorescence Microscopy; Infiltration; Migration; Killing;

   Sammanfattning : Natural Killer cells are a type of lymphocyte belonging to the innate immune system and they operate cell-mediated cytotoxicity and release of pro-inflammatory cytokines against cancerous cells. However, in vivo testings have shown a reduced activity of NK cells against solid tumors probably due to the negative influence of the immunosuppressive tumor microenvironment. LÄS MER

5. 4. Evaluation of Amyloid Fibrils as Templates for Photon Upconversion by Sensitized Triplet-Triplet Annihilation

   Kandidat-uppsats, KTH/Skolan för kemivetenskap (CHE)

   Författare :Sharon Berkowicz; Helena Olsson; Henrik Broberg; [2017]
   Nyckelord :photon upconversion; sensitized triplet-triplet annihilation; anti-stokes emission; amyloid fibrils; whey protein;

   Sammanfattning : In the face of global warming and shrinking resources of fossil fuels the interest in solar energy has increased in recent years. However, the low energy and cost efficiency of current solar cells has up to this date hindered solar energy from playing a major role on the energy market. LÄS MER

7. 5. Selective Plane Illumination Microscopy Using Non-spreading Airy Beams

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Författare :Aleksandrs Leitis; [2016]
   Nyckelord :Microscopy; Selective Plane Illumination Microscopy; Light Sheet Microscopy; Physics and Astronomy;

   Sammanfattning : Recently a new field of microscopy has emerged, known as selective plane illumination microscopy (SPIM). Using a SPIM setup the sample is illuminated with a thin light sheet from the side. The selective plane illumination overcomes many problems that conventional microscopes have. LÄS MER
