1. 1. Cell Identification from Microscopy Images using Deep Learning on Automatically Labeled Data

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Fredrik Salomon-Sörensen; [2023]
   Keywords : Deep Learning; Cell Identification; Image Segmentation; Nuclei Segmentation; Convolutional Neural Networks; UNet; Image Analysis; Microscopy; Noisy Labels; Phase-Contrast; Automatic Labeling; Technology and Engineering;

   Abstract : In biology, cell counting provides a fundamental metric for live-cell experiments. Unfortunately, most researchers are constrained to using tedious and invasive methods for counting cells. Automatic identification of cells in microscopy images would therefore be a valuable tool for such researchers. READ MORE

3. 2. Generative Modelling and Probabilistic Inference of Growth Patterns of Individual Microbes

   University essay from Linköpings universitet/Statistik och maskininlärning

   Author : Shashi Nagarajan; [2022]
   Keywords : Generative modelling; probabilistic inference; Nuisance Variable Elimination; Variational Inference; microfluidic single cell cultivations;

   Abstract : The fundamental question of how cells maintain their characteristic size remains open. Cell size measurements made through microscopic time-lapse imaging of microfluidic single cell cultivations have posed serious challenges to classical cell growth models and are supporting the development of newer, nuanced models that explain empirical findings better.

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

   University essay from KTH/Tillämpad fysik

   Author : Emil Sorcini; [2022]
   Keywords : 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;

   Abstract : 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. READ MORE

5. 4. In-vivo imaging of root growth in response to localized mechanical stress

   University essay from SLU/Dept. of Soil and Environment

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

   Abstract : 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. READ MORE

6. 5. Investigation on Cell-Cell Junctions by Inhibition of Na,K-ATPase Activity

   University essay from KTH/Tillämpad fysik

   Author : Caroline Boström; [2021]
   Keywords : 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;

   Abstract : 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. READ MORE
