  1. 1. Multiparameter flow cytometry : methodological aspects and applications to T cell activation

    Författare :Roger Festin; Uppsala universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : .... LÄS MER

  3. 2. Flow cytometry for bioprocess control

    Författare :Fredrik Wållberg; KTH; []
    Nyckelord :flow cytometry; partec pas; propidium iodide;

    Sammanfattning : During bio-technical processing it is important to monitorbiological parameters such as cell growth, viability andproduct formation. Many of the analyses traditionally used areslow to perform and provide only average data for thepopulation. LÄS MER

  4. 3. Telomere analysis of normal and neoplastic hematopoietic cells : studies focusing on fluorescence in situ hybridization and flow cytometry

    Författare :Magnus Hultdin; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicine; telomere; telomerase; fluorescence in situ hybridization; flow cytometry; flow-FISH; replication timing; chronic lymphocytic leukemia; immunoglobulin gene; prognosis; Biomedicin; Microbiology; Mikrobiologi; Medical Cell Biology; medicinsk cellbiologi;

    Sammanfattning : The telomeres are specialized structures at the end of the chromosomes composed of the repeated DNA sequence (TTAGGG)n and specific proteins bound to the DNA. The telomeres protect the chromosomes from degradation and end to end fusions. LÄS MER

  5. 4. Simulation of individual cells in flow

    Författare :Lailai Zhu; Luca Brandt; Michael Graham; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrodynamic interaction; swimming microorganisms; capsule; Stokes flow; finite element method; boundary integral method; general geometry Ewald method; spectral element method; viscoelastic fluid; cellular deformation; flow cytometry; cell sorting; microrheology; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : In this thesis, simulations are performed to study the motion ofindividual cells in flow, focusing on the hydrodynamics of actively swimming cells likethe self-propelling microorganisms, and of passively advected objects like the red bloodcells. In particular, we develop numerical tools to address the locomotion ofmicroswimmers in viscoelastic fluids and complex geometries, as well as the motion ofdeformable capsules in micro-fluidic flows.

  7. 5. Acoustic Forces in Cytometry and Biomedical Applications: Multidimensional Acoustophoresis

    Författare :Carl Grenvall; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Microfluidics; Ultrasound; Multinode; Cell Sorting; Particle Positioning; Cytometry; Lab-on-a-Chip; µTAS; Binary Separation; Acoustic Barriers; Acoustic Particle Manipulation; Acoustic Standing Waves; Blood Separation; Milk Analysis;

    Sammanfattning : Over the last decades the ongoing work in the fields of Lab-on-a-Chip and Micro-Total-Analysis-Systems has led to the discovery of new or improved ways to handle and analyse small volumes of biofluids and complex biosuspensions. The benefits of working on the microscale include: miniaturization of the analysis systems with less need for large sample volumes; temporal and spatial control of suspended particle/cell positions; low volume sheath flow lamination or mixing; novel separation techniques by using forces inherent to the microscale domain; precise regulation of sample temperatures and rapid analysis with less volumes needed to be processed.
