  1. 16. Endometrial receptivity and regeneration in health and disease : molecular, cellular and clinical perspectives

    Författare :Carolina von Grothusen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Each month, the endometrium regenerates under the influence of the ovarian hormones and builds up to a receptive state in preparation for embryo implantation. In the absence of pregnancy, it sheds during menses and the regenerative cycle starts again. LÄS MER

  3. 17. Numerical studies of receptivity, stability and transition of wing and turbine blade boundary layers

    Författare :Luca De Vincentiis; Ardeshir Hanifi; Dan S. Henningson; Stefania Cherubini; KTH; []
    Nyckelord :Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : In the present thesis, receptivity, stability and laminar-turbulent transition of different boundary-layer flows are addressed and investigated by means of direct numerical simulations. In particular, flows over a wing and a low-pressure-turbine (LPT) blade have been the main focus. LÄS MER

  4. 18. Sexual conflict and selection on pistil and pollen traits

    Författare :Josefin Madjidian; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antagonistic trait; Collinsia heterophylla; delayed stigma receptivity; direct cost; first-donor advantage; gender bias; heritability; indirect benefit; mate choice; mixed-mating system; paternal diversity; pollen competition; pollen deposition; pollen load size; pollen tube growth rate; self-compatibility; semantics; sexual conflict; sexual selection; sexually antagonistic co-evolution;

    Sammanfattning : The incidence of sexual selection in plants is today acknowledged, however, just as in animals, evolution and maintenance of mate choice is gravely underexplored. Moreover, the potential for sexual conflicts to occur in plants has only been assessed empirically to a very limited degree. LÄS MER

  5. 19. Levonorgestrel emergency contraception : effects on endometrial development and embryo implantation

    Författare :Chun-Xia Meng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Emergency contraception; levonorgestrel; endometrial receptivity markers; embryo implantation; first-trimester tissues;

    Sammanfattning : Background: The dialog between the developing embryo and receptive endometrium is under the control of ovarian steroids and numerous biomolecules, some of which have been suggested as markers of endometrial receptivity. Unintended pregnancies are common. The standard treatment with levonorgestrel (LNG, 1. LÄS MER

  7. 20. Effects of mifepristone on the human endometrium and the fallopian tube during the luteal phase

    Författare :Xiaoxi Sun; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Mifepristone; endometrial receptivity; emergency contraception; PR-B; eNOS; IGFBP-1; PRL; HB-EGF; HB-EGF receptors HER1 and HER4;

    Sammanfattning : Mifepristone given postovulatory has been shown effective for contraception, but the precise mechanism of action is still poorly understood. A better understanding of the mechanisms of action of mifepristone, when used for contraception, is important for further development and optimizing the regimen of use. LÄS MER
