  1. 16. Reproductive aspects of the protein C system in women

    Författare :Margareta Wramsby; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Hypercoagulation; Factor V Leiden; APC resistance; Protein C inhibitor; Recurrent abortions; Menstrual cycle; Pregnancy; Controlled ovarian hyperstimulation.;

    Sammanfattning : Of great importance to the reproductive system in women are the activating and inhibiting factors which maintain haemostatic balance. These play a prominent role in the prevention of abnormal bleeding, at ovulation as well as during menstruation, pregnancy and delivery. The coagulation cascade is primarily down regulated by the protein C system. LÄS MER

  2. 17. Endometrial receptivity and development of new contraceptive methods

    Författare :Lena Marions; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Mifepristone; levonorgestrel; endometrial receptivity; emergency contraception; blastocyst implantation; integrins; cyclooxygenase;

    Sammanfattning : Ovulation and endometrial development as well as contraceptive efficacy was studied after treatment with the antiprogestin mifepristone. Mechanism of action after treatment with the gestagen levonorgestrel or mifepristone in doses effective for emergency contraception was also evaluated. LÄS MER

  3. 18. Acupuncture in reproductive medicine. Applications in human assisted reproduction and aspects of clinical and experimental neuroendocrinology

    Författare :Elisabet Stener-Victorin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electro-acupuncture; blood flow impedance; circulation; uterine artery; in-vitro fertilization; oocyte aspiration; polycystic ovary syndrome; experimentally induced PCO; anovulation; gonadotropins; steroids; neuropeptides; b-endorphin; nerve growth factor; corticotropin-releasing factor.;

    Sammanfattning : The use of acupuncture in the area of reproductive medicine is relatively new, and it has been rather poorly investigated in the past. When muscle afferents are stimulated by acupuncture in somatic segments related to the innervation of the ovaries and the uterus, functional changes occur in the neural substrate that may influence reproductive function and result in peripheral, segmental and central effects.

  4. 19. Reproductive physiology of the female three-spined stickleback, Gasterosteus aculeatus

    Författare :Chrysoula Roufidou; Bertil Borg; Geir Lasse Taranger; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; overripening of eggs; spawning cycle; brain-pituitary-gonad BPG axis; vitellogenin; ovarian fluid; sex steroids; reproduction; three-spined stickleback; Gasterosteus aculeatus; fish; funktionell zoomorfologi; Functional Zoomorphology;

    Sammanfattning : Reproduction in vertebrates, including fishes, is under control of the brain-pituitary-gonad (BPG) axis. The female three-spined stickleback, Gasterosteus aculeatus, produces egg clutches at intervals of a few days and spawns them in a nest built by male. LÄS MER

  5. 20. Expression, regulation and fuction of small ubiquitin-related modifier-1. Interaction with nuclear proteins in vivo

    Författare :Linus Ruijin Shao; Göteborgs universitet; []
    Nyckelord :SUMO-1; LH receptor; PR isoforms; caspase-3; DNA fragmentation; apoptosis; granulosa cells; HIF-1alpha; hypoxia; brain and heart;

    Sammanfattning : The small ubiquitin-related modifier-1 (SUMO-1) is a 101-amino acid, ~12 kDa protein that is 18% identical to ubiquitin. Posttranslational covalent tagging of proteins with SUMO-1 (SUMOylation) serves many functions. For example, regulation of protein stability and modulation of transcriptional activation. LÄS MER
