  1. 21. Toward a tissue engineered blood vessel. Cell cultivation, hemodynamic influences and matrix production

    Författare :Sepideh Heydarkhan-Hagvall; Göteborgs universitet; []
    Nyckelord :tissue engineered blood vessel; co-culture vascular cells; angiogenic factors; ; hemodynamic; extracellular matrix; stem cells;

    Sammanfattning : Cardiovascular diseases are the leading causes of mortality in the western world. Thereplacement or repair of diseased blood vessels with human autografts (vein or arteries) orsynthetic vascular grafts (ePTFE or Dacron) has become a routine treatment. Autologous graftsare not always available in all patients. LÄS MER

  2. 22. Laboratory Soft X-Ray Cryo Microscopy: Source, System and Bio Applications

    Författare :Emelie Fogelqvist; Hans Hertz; David Attwood; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; X-ray optics; Instrumentation; Laser plasma; Cryofixation; Tomography; Tomographic reconstruction; Autophagy; Immune synapse; Physics; Fysik; Physics;

    Sammanfattning : Soft x-ray microscopes routinely perform high-resolution 3D imaging of biological cells in their near-native environment with short exposure times at synchrotron radiation facilities. Some laboratory-sized microscopes are aiming to make this imaging technique more accessible to a wider scientific community. LÄS MER

  3. 23. Interactions between the stroma and thyroid epithelial cells of normal and malignant origin

    Författare :Thérèse Dahlman; Uppsala universitet; []
    Nyckelord :Medical sciences; Thyroid gland; carcinoma; collagen type I; EGF; TGF-b1; interaction; integrins; E-cadherin; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : Endocrine and locally produced factors as well as interactions between epithelial cells and the stroma important in the control of growth and function of the thyroid gland. In this study, the effects of, and mechanism(s) for, such cross-talk under some normal and pathological conditions were investigated. LÄS MER

  4. 24. Mechanistic studies on the role of extracellular vesicles in the tumor microenvironment

    Författare :Helena Christianson; Tumörmikromiljö; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microvesicle; exosome; Key words Extracellular vesicle; glioblastoma; hypoxia; angiogenesis; acidosis; proteoglycan; endocytosis; carbonic anhydrase IX; biomarker.;

    Sammanfattning : The transition from normal into malignant cells with acquired uncontrolled growth is a process where cancer cells viciously develop adaptive strategies to overcome microenvironmental and metabolic stress. Hypoxia, or deficient oxygen supply, is a common feature of the expanding tumor which alters cell metabolism and consecutively causes lowered intracellular pH. LÄS MER

  5. 25. Long non-coding RNAs and cellular interactions : investigating underlying mechanisms of oncogenesis

    Författare :Jason T Serviss; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cancer is a leading cause of death worldwide with one in 8 men and one in 11 women dying from the disease (World Health Organization, 2018). Despite vast improvements in cancer diagnosis and therapy, the global cancer burden continues to rise in unison with population growth and longevity. LÄS MER
