  1. 1. Progesterone metabolites learning, tolerance, antagonism & metabolism

    Detta är en avhandling från Umeå : Umeå university

    Författare :Charlotte Öfverman; Umeå universitet.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allopregnanolone; isoallopregnanolone; THDOC; learning; tolerance; antagonism; inhibition; patch clamp; Morris water maze; metabolism; epimerization; MEDICINE Surgery Obstetrics and women s diseases Obstetrics and gynaecology; MEDICIN Kirurgi Obstetrik och kvinnosjukdomar Obstetrik och gynekologi; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Progesterone metabolites as allopregnanolone, isoallopregnanolone and tetrahydrodeoxy-corticosterone (THDOC) are increased in the luteal phase of the menstrual cycle, throughout pregnancy and during stress. Allopregnanolone and THDOC are neurosteroids with 3α-hydroxy, 5α-configurations and positive modulating effect on the GABAA receptor. LÄS MER

  2. 2. The role of progesterone in the regulation of ciliary activity in the fallopian tube

    Detta är en avhandling från Umeå : Umeå university

    Författare :Magdalena Nutu; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; progesterone; progesterone receptor; non-genomic progesterone receptor; ciliated cells; fallopian tube; gamete transport; ciliary activity; ciliary beat frequency; reproduction; fertility;

    Sammanfattning : The overall aim of this thesis was to investigate the distribution and regulation of membrane progesterone receptors (mPRs) that may be involved in regulating ciliary activity in the fallopian tube. The fallopian tube serves to transport the egg and spermatozoa to achieve fertilization. LÄS MER

  3. 3. Progesterone in human parturition : progesterone and 5α-pregnane-3,20-dione in relation to human myometrial activity

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Mats Löfgren; Umeå universitet.; [1991]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : This study was undertaken to evaluate the relationship of progesterone and 5α-pregnane-3,20-dione (5αDHP), a major progesterone metabolite, to human parturition. The serum concentrations of 5αDHP prior to, during and following parturition were to be established, as well as its maternal and fetal concentration in different modes of delivery. LÄS MER

  4. 4. Allopregnanolone and mood studies of postmenopausal women during treatment with progesterone

    Detta är en avhandling från Umeå : Klinisk vetenskap

    Författare :Lotta Andréen; Umeå universitet.; [2006]
    Nyckelord :Obstetrics and gynaecology; Progesterone; Allopregnanolone; GABA; mood; bimodal; Obstetrik och kvinnosjukdomar;

    Sammanfattning : Introduction. Allopregnanolone and pregnanolone (neuroactive metabolites of progesterone) act as positive modulators of the GABAA receptor system which is the major inhibitory system in CNS. Contradictory results on the effect of GABAA receptor modulators are reported. LÄS MER

  5. 5. Granulosa cell apoptosis: Transcriptional regulation by the nuclear progesterone receptor

    Detta är en avhandling från Umeå : Klinisk vetenskap

    Författare :P. Anders Friberg; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ovary; granulosa cells; ovulation; luteinization; progesterone; apoptosis; cholesterol synthesis; isoprenylation;

    Sammanfattning : Ovarian follicle atresia caused by granulosa cell apoptosis is a central process in normal female physiology. Progesterone has been reported to be a survival factor in granulosa cells at several developmental stages. LÄS MER
