  1. 31. Oocyte maturation in a contaminated environment : effects of perfluoroalkyl substances on bovine early embryo development in vitro

    Författare :Ida Hallberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The content of this thesis is dedicated to female fertility, and more specifically the maturing oocyte. The aim was to investigate chemicals present in the direct environment of the oocyte and more specifically to investigate the sensitivity of the oocyte to perfluoroalkyl substances (PFASs) using a bovine in vitro embryo production model.

    Sammanfattning : This thesis aims to study the effects of endogenous and exogenous hormones and mammographic breast density (BD) on cellular markers in non-cancerous female breast tissue. Women on the waiting list for breast reduction plastic surgery were recruited (n = 79), and randomized to 2 months of hormone therapy or no therapy before surgery. LÄS MER

  4. 33. Allopregnanolone effects in women : clinical studies in relation to the menstrual cycle, premenstrual dysphoric disorder and oral contraceptive use

    Författare :Erika Timby; Marie Bixo; Torbjörn Bäckström; Anna-Carin N Wihlbäck; C Neill Epperson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allopregnanolone; GABAA receptor; menstrual cycle; premenstrual dysphoric disorder; saccadic eye velocity; oral contraceptives; hypothalamic amenorrhea;

    Sammanfattning : Background: Premenstrual dysphoric disorder (PMDD) affects 3–8% of women in fertile ages. Combined oral contraceptives (OCs) are widely used and some users experience adverse mood effects. The cyclicity of PMDD symptoms coincides with increased endogenous levels of allopregnanolone after ovulation. LÄS MER

  5. 34. Intraovarian regulators of the ovulatory process. Studies in the rat and human

    Författare :Marita E. Pall; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : LH stimulation of the preovulatory follicle results in extensive biochemical and morphological changes which lead to follicle rupture. Many redundant and parallel functioning mediator systems are involved in this process. LÄS MER
