  2. 11. Time-Lapse Microscopy Imaging and Image Analysis for Cell Migration Studies

    Author : Johan Degerman; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cell image segmentation; computational imaging; cell migration modelling; Time-lapse microscopy;

    Abstract : This thesis considers a complete automatic system for in-vitro cell imaging and migration image analysis. The development of such can be divided into three main problems:The first considered problem concerns how to build a robust time-lapse sequence acquisition system, for imaging adult hippocampal cells in bright-field microscopy.

  4. 12. Microwell devices for single-cell analyses

    Author : Sara Lindström; Helene Andersson-Svahn; Mehmet Toner; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microwell; miniaturization; microfluidics; cell culture; single-cell; clone; imaging; stem cell; cancer; low volume; high-throughput; Molecular biology; Molekylärbiologi;

    Abstract : Powerful tools for detailed cellular studies are emerging, increasing the knowledge ofthe ultimate target of all drugs: the living cell. Today, cells are commonly analyzed inensembles, i.e. thousands of cells per sample, yielding results on the average responseof the cells. READ MORE

  5. 13. Motility of human polymorphonuclear leukocytes : An image processing approach

    Author : Mikael Gustafsson; Erik Gylfe; Linköpings universitet; []
    Keywords : Human polymorphonuclear leukocytes; locomotion; phagocytosis; Saccharomyces cerevisiae; membrane transport; intracellular free calcium; cellular pH; water influx; actin dynamics; digital video microscopy; image processing; fura-2; BCECF; DII; MEDICINE; MEDICIN;

    Abstract : Cell motility is essential for polymorphonuclear leukocyte (PMN) function in the defense against invading microorganisms and in inflammatory processes. Using digital video microscopy and image processing, individual cells were studied during random locomotion, chemotactic locomotion and phagocytosis. READ MORE

  6. 14. On boundary value problems for intracellular subdiffusion and signaling pathways, and for geometric flows

    Author : Tobias Gebäck; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; boundary value problems; diffusion-reaction equations; signaling pathways; anomalous diffusion; pseudo-differential equations; fluorescence correlation spectroscopy; immersed interface method; Boolean grids; mean curvature flow; pseudo-differential equations; boundary value problams; flourescence correlation spectroscopy;

    Abstract : The main part of this thesis concerns mathematical models for diffusion of proteins inside cells, including reactions between the proteins. Initially, such models are applied to describe signaling pathways in yeast cells, and the properties of the model are studied, especially in relation to models that do not include diffusion.

  7. 15. Numerical Study of Fluid-Structure Interaction with Application to Oscillating Cylinders

    Author : Mikhail Lazarkov; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lock-in.; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; synchronization; flow-induced vibration; LES; Volume of Solid method; Virtual Boundary method; vortex-shedding; confined cylinder; Fluid-structure interaction; wake;

    Abstract : The problem of fluid-structure interaction, occurring in many industrial and engineering applications, are of great importance, since interaction of a flow and a structure in it can lead to serious damages of the structure. The fluid-structure interaction gives rise to a variety of different physical phenomena such as flow-induced vibration, noise generation, etc. READ MORE
