  1. 6. Hypoxia-inducible factors (HIFs) and biological responses, in hypoxia, inflammation and embryonic vascular development

    Författare :Maria Hägg; Göteborgs universitet; []
    Nyckelord :Embryonic stem cell; embryoid body; HIF-1a; hypoxia; VEGF; angiogenesis; vasculogenesis; peritoneal dialysis;

    Sammanfattning : ABSTRACT Low oxygen tension (hypoxia) is a major inducer of neovascularisation and evidence emerging has indicated that oxygen tension and hypoxia-inducible factors (HIFs), a family of oxygen-regulated heterodimeric transcription factors, may play important roles in vascular and hematopoietic development. This thesis has focused on studying molecular and cellular mechanisms, by which cells and organisms sense changes in oxygen tension, and how this signal is transduced by HIFs into downstream signalling.

  3. 7. Acute inflammation in peritoneal dialysis. Experimental studies in rats. Characterization of regulatory mechanisms

    Författare :Farhan Bazargani; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The predominant problems associated with peritoneal dialysis (PD) are ultrafiltration failure and peritonitis. PD maintains a state of intraperitoneal inflammation that affects the structure and function of the peritoneal membrane, potentially impairing ultrafiltration efficiency. LÄS MER

  4. 8. Invasion promoting factors in endometriotic and endometrial tissue

    Författare :Christina Bruse; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Endometriosis; endometrium; PF; tPA; uPA; uPAR; PAI-1; PAI-2; IL-1beta; IL-6; TNFalpha.;

    Sammanfattning : Endometriosis is a common gynaecologic disorder, affecting women of fertile age with pelvic pain and infertility, and is characterized by the presence of endometrial glands and stroma outside the uterine cavity. Retrograde shed endometrial fragments are presumed to adhere to pelvic structures and grow invasively, thereby creating endometriotic tissue. LÄS MER

  5. 9. Studies of SIRPα-mediated regulation of neutrophil functions

    Författare :Åsa Stenberg; Janove Sehlin; Karl-Eric Magnusson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; SIRPα; inflammation; adhesion; chemotaxis; apoptosis;

    Sammanfattning : Neutrophil granulocytes constitute the front line of defense in the innate immune response to invading microorganisms, but can also contribute to development of inflammatory disease and tissue destruction following e.g. myocardial infarction or stroke. LÄS MER

  7. 10. Tissue reactions to biomaterials

    Författare :Agneta Rosengren; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytochemistry; Histology; Macrophages; Cryosubstitution; Proteins; Immunohistochemistry; Titanium; Implants; PTFE; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

    Sammanfattning : The biological response to different implanted biomaterials vary. The relative importance of factors in the material and host for this variation are at present incompletely known. LÄS MER
