  2. 16. 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

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

    Abstract : 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. READ MORE

  4. 17. Molecular pathways mediating the development of female germ cells

    Author : Sanjiv Risal; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ovary; primordial follicles; primordial germ cells; Oogonial stem cells;

    Abstract : In mice, primordial germ cells (PGCs) dramatically increase in their number from 200 cells at 9.5 dpc to 10 000 cells at 12.5 dpc with doubling time of 12.6 hours. READ MORE

  5. 18. Structure and function of the HDL receptor SR-BI : scavenger receptor class B type I

    Author : Magnus S.C. Johnson; Göteborgs universitet; []
    Keywords : SR-BI; HDL; Cholesterol; Scavenger receptor; Apoptosis; Ovary; Gallbladder; Peroxisome;

    Abstract : Low plasma levels of high-density lipoprotein (HDL) and high levels of low-density lipoprotein (LDL) are well-recognized risk factors for cardiovascular disease. The uptake and degradation of LDL cholesterol have been characterized in detail at the molecular level. Less is known about the metabolism and cellular uptake of HDL cholesterol. READ MORE

  6. 19. Human ovulation. Studies on collagens, gelatinases and tissue inhibitors of metalloproteinases

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

    Abstract : 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. READ MORE

  7. 20. Signaling pathways in the development of female germ cells

    Author : Deepak Adhikari; Kui Liu; Elisabet Stener-Victorin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ovary; primordial follicle; activation; mTORC₁; PI₃K; oocyte maturation; MPF; Cdk₁; medicinsk biokemi; Medical Biochemistry;

    Abstract : Primordial follicles are the first small follicles to appear in the mammalian ovary. Women are born with a fixed number of primordial follicles in the ovaries. Once formed, the pool of primordial follicles serves as a source of developing follicles and oocytes. READ MORE
