  1. 21. Nucleic acid tools for detection and characterization of biological systems

    Författare :Ioanna Smyrlaki; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nucleic acids, DNA and RNA, are naturally occurring biopolymers synthetized by cells to store and propagate genetic information. They can be found in eukaryotic cells, bacteria, archaea and viruses and, thanks to the development of synthetic chemistry techniques, they can be synthetized with relative ease on demand in the laboratory.

  3. 22. Studies of transforming growth factor alpha in normal and abnormal growth

    Författare :Anna-Lotta Hallbeck; Åke Wasteson; Thomas Walz; Annelie Lindström; Carl-Henric Heldin; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-alpha; HER; EGFR; synovia; synovial sarcoma; RA; synovitis; Medical cell biology; Medicinsk cellbiologi;

    Sammanfattning : Regulation of growth is of fundamental importance for development of the organism and to maintain health. The induction of cell proliferation and matrix production are influenced by several different signaling systems, most importantly by growth factors. LÄS MER

  4. 23. Follicular lymphoma : clinical and biological factors associated with response to therapy and overall prognosis

    Författare :Sandra Johanna Young Lockmer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Follicular lymphoma (FL) is a heterogeneous group of malignancies within the adaptive immune system. The clinical course is highly variable. Treatment includes different chemotherapy regimens as well as the anti-CD20 monoclonal antibody rituximab which has significantly improved the prognosis for patients with all types of B cell lymphomas.

  5. 24. Modeling Biophysical Mechanisms underlying Cellular Homeostasis

    Författare :Padideh Kamali-Zare; Hjalmar Brismar; Charles Nicholson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biological physics; Biologisk fysik;

    Sammanfattning : Cellular homeostasis is the effort of all living cells to maintain their intracellular content when facing physiological change(s) in the extracellular environment. To date, cellular homeostasis is known to be regulated mainly by time-consuming active mechanisms and via multiple signaling pathways within the cells. LÄS MER

  7. 25. Biological interface of bone graft substitute materials : experimental studies on interactions between biomaterials and bone cells

    Författare :Zivko Mladenovic; Maria Ransjö; Joost D de Brujin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Bone graft substitute materials are becoming more common as alternative therapy strategies when bone defects in patients need to be treated. The interaction between bone cells and biomaterials occur at the surface of the materials. A great deal is known about the importance of surface topography and physic-chemical properties of biomaterials. LÄS MER
