  1. 1. Flow cytometry for bioprocess control

    University dissertation from Stockholm : Bioteknologi

    Author : Fredrik Wållberg; KTH.; [2004]
    Keywords : flow cytometry; partec pas; propidium iodide;

    Abstract : 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. READ MORE

  3. 3. Studies of the physiological status of bacteria used for environmental applications

    University dissertation from Stockholm : Karolinska Institutet, Department of Laboratory Medicine

    Author : Ninwe Maraha; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Today, it is difficult to study the physiological status of inoculants in complex environments, such as soil. In this thesis, we describe the combined use of marker genes and viability stains to determine the physiological status of the bacterial cells in pure cultures and in soil. READ MORE

  4. 4. The role of the MAP- and SAP- kinase pathways in the survival, proliferation and death of Schwann cells of the injured sciatic nerve

    University dissertation from Department of Biology, Lund University

    Author : Lisa Mårtensson; Lund University.; Lunds universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis concerns alterations in signal transduction in Schwann cells as a response to nerve injury as well as their survival, proliferation and death. Enzymes and transcription factors belonging to the mitogen activated protein kinase (MAPK) and the stress activated protein kinase (SAPK) pathways were studied. READ MORE

  5. 5. Macrophage-material surface interactions

    University dissertation from Göteborg

    Author : Christina Gretzer; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apoptosis; biomaterials; cell-cell interactions; cell-material interactions; cytokines; differentiation; fibrinogen; hydrogen peroxide; LPS; monocytes; particles;

    Abstract : Material surface-stimulated activation of the macrophage and the release of mediators has been suggested to be an important factor for inflammation and tissue regeneration around biomedical implants. Macrophage interactions with particles released from implants as well as macophage-bacteria interactions are also involved in implant loosening processes. READ MORE
