  1. 1. Chemotactic factors in the human follicle at ovulation

    Författare :Eva Runesson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chemokine; follicle; gonadotropin; human; ovary; ovulation;

    Sammanfattning : Ovulation is initiated by the midcycle gonadotropin surge, which leads to a controlled degradation of the follicle wall ending in follicular rupture and oocyte extrusion. The gonadotropins triggers several biochemical and biophysical changes such as vascular alterations, increased proteolytic enzyme activity and leukocyte extravasation, within the preovulatory follicle.

  3. 2. 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

  4. 3. Blood flow and metabolism in the corpus luteum of the rat : in vivo and in vitro studies on the ovarian luteal and follicular compartment of the rat

    Författare :Mats Gåfvels; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ovary; follicle; corpus luteum; blood flow; metabolism; luteinizing hormone; noradrenaline; antidiuretic hormone;

    Sammanfattning : The ovary undergoes cyclic changes in follicular growth and luteogenesis due to the action of gonadotropins and steroids. The ovary and especially the corpus luteum has an exteremely high blood flow. There is a gap in our knowledge about the physiological role of the high blood flow of the corpus luteum. LÄS MER

  5. 4. The Ovulatory Process. Studies in the human and the rabbit

    Författare :Pernilla Dahm-Kähler; Göteborgs universitet; []
    Nyckelord :ovulation; ovary; rabbit; human; follicle; MCP-1; intrafollicular pressure;

    Sammanfattning : Background and general summary: Ovulation is the cascade of events ending with follicular rupture and oocyte extrusion. This ovulatory process is triggered by the LH surge, which induces biochemical and biophysical alterations within the preovulatory follicle. LÄS MER

  7. 5. Barrier function of the Follicle-Associated Epithelium in Stress and Crohn's disease

    Författare :Åsa Keita; Johan D. Söderholm; Ann-Charlott Ericson; Björn Weström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Corticotropin-releasing hormone; Crohn’s disease; 51Cr- EDTA; Escherichia coli; follicle-associated epithelium; horseradish peroxidase; human; ileum; inflammatory bowel disease; intestinal mucosa; mast cell; M cell; permeability; Peyer’s patches; rat; Ussing chamber; vasoactive intestinal peptide; villus epithelium; Surgery; Kirurgi;

    Sammanfattning : Crohns sjukdom är en kronisk inflammatorisk tarmsjukdom av okänd orsak. Det tidigaste tecknet på Crohns sjukdom är mikroskopiska sår i det s.k. follikelassocierade epitelet (FAE) som täcker ansamlingar av immunceller i tarmen. LÄS MER
