  1. 1. The Entheses of the Medial Meniscns and Ligaments of the Knee Joint : Descriptive and Experimental Studies

    Författare :Jizong Gao; Michael Benjamin; Linköpings universitet; []
    Nyckelord :knee joint; meniscus; ligaments; insertion; enthesis; quantitative morphology; fibrocartilage; cement line; collagens; proteoglycans; nerve fibres; tensile strength; failure mode; transection; refixation; repair; healing; osteoarthrosis; histology; immunohistochemistry; biomechanics; rabbit model; MEDICINE; MEDICIN;

    Sammanfattning : Meniscal injuries are common in sports. Surgical removal of the meniscus to relieve symptoms is associated with a high risk for late knee joint osteoarthrosis and pain. Meniscal repair or replacement has therefore been advocated. LÄS MER

  3. 2. Basement membrane collagens in pancreatic cancer : novel stroma-derived tumor markers and regulators of cancer cell growth

    Författare :Daniel Öhlund; Malin Sund; Peter Naredi; Matthias Löhr; Umeå universitet; []
    Nyckelord :Pancreatic cancer; tumor marker; basement membrane; type IV collagen; type XVIII collagen; matrix metalloproteinase; integrin; autocrine loop; tumor stroma; kirurgi; Surgery;

    Sammanfattning : Background: Among the common malignancies, pancreatic cancer has the shortest long-term survival. The aggressive, rapid, and infiltrative growth pattern of pancreatic cancer, together with the lack of specific symptoms, often leads to late diagnosis. LÄS MER

  4. 3. Stromal collagens in colorectal cancer and in colorectal liver metastases : tumour biological implications and a source for novel tumour markers

    Författare :Hanna Nyström; Malin Sund; Peter Naredi; Per Sandström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; colorectal liver metastases; tumour marker; stroma; type IV collagen; metastatic growth pattern; kirurgi; Surgery;

    Sammanfattning : Background: Colorectal cancer (CRC) remains one of the leading causes of cancer-related mortality. About 50 % of patients with CRC will develop subsequent liver metastases (CLM). The survival for untreated CLM is only a few months and liver resection provides the only chance for a lasting cure. LÄS MER

  5. 4. Human ovulation. Studies on collagens, gelatinases and tissue inhibitors of metalloproteinases

    Författare :Anna Karin Lind; Göteborgs universitet; []
    Nyckelord :ovulation; ovary; human; follicle; collagen; MMP and TIMP;

    Sammanfattning : Ovulation is a highly regulated process, which involves the degradation and rupture of healthy tissue of the ovarian follicle and the extrusion of a fertilizable oocyte. This unique biological process is initiated by the LH-surge, which induces major vascular changes and remodelling of the extracellular matrix (ECM) in and around the follicle. LÄS MER

  7. 5. Gene expression during hard tissue formation

    Författare :Catharina Ellerström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :bone; dentin; mRNA; fibrillar collagens; osteonectin; fibronectin; development; rat;

    Sammanfattning : The purpose of this thesis was to study the formation of the extracellular matrix (ECM) of bone and dentin during development. Molecular techniques, such as in situ hybridization and RT-PCR, were used to investigate the occurrence of specific gene products in formative cells. LÄS MER
