1. 6. 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

3. 7. In-vivo imaging of root growth in response to localized mechanical stress

   Master-uppsats, SLU/Dept. of Soil and Environment

   Författare :Leah Eitelberg; [2022]
   Nyckelord :kinematics analysis; time-lapse imaging; root growth rate; root curvature; soil heterogenety; local mechanical stress;

   Sammanfattning : By taking up nutrients and water, root growth has an important influence on plant growth and productivity. Thereby, root growth is influenced by its surrounding soil conditions, which vary spatially even on a small scale. Hence, different parts of the root system are exposed to different penetration resistances in the soil. LÄS MER

4. 8. Investigation on Cell-Cell Junctions by Inhibition of Na,K-ATPase Activity

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Caroline Boström; [2021]
   Nyckelord :NaK-ATPase; Ouabain; Cell junctions; ECadherin; Occludin; Claudin7; Western Blot; Fluorescent Imaging; Tight junctions; Adherens Junctions; Immunocytochemistry; Ouabain; NaK-ATPase; ECadherin; Occludin; Claudin7; Western Blot; Immunocytokemi; Cellkontakter; Fluorescernsmikroskopi;

   Sammanfattning : This thesis report investigates the effect on cellcell junction proteins when the Na,K-ATPase (NKA) is inhibited. The main goal is to develop an understanding of how the NKA activity regulates the cell junction proteins. The investigated proteins are the adherens junction protein ECadherin, and the tight junction proteins Occludin and Claudin7. LÄS MER

5. 9. Multi-method based characterization of calving events at Sálajiegna Glacier - Lake Sulitelma, Northern Sweden

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Martin Schulthess; [2021]
   Nyckelord :Glaciology; Glacier; Glaciers; Calving; calving front; detection algorithm; Acoustic; Acoustics; Photogrammetry; ice-ocean interactions; UAV; drone; time-lapse; Salajiegna;

   Sammanfattning : Sea level rise concerns millions of people in coastal areas across the globe. One of the largest uncertainties to project future sea level rise is the frontal ablation (accounting for calving and submarine melt) at marine ice margins, around the Greenland and Antarctic Ice Sheet.

7. 10. Antibiotic combination therapies against carbapenamse producing Klebsiella pneumoniae

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Thomas Söderhäll; [2021]
   Nyckelord :Klebsiella pneumoniae; carbapenem resistance; carbapenemase; combination therapy; meropenem; colistin; avibactam; constucts; porins;

   Sammanfattning : The treatment options for multidrug resistant bacteria are dwindling and it is an important issue of research in medicine to solve. One of the more problematic bacterial species is Klebsiella pneumoniae, it can cause infections with high morbidity that are difficult to treat. LÄS MER
