  2. 11. Host-microbe interactions : gut microbiota and its effects on developmental programming of the brain, placenta and testis

    Author : Maha Al-Asmakh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Reproduction of a mammalian organism involves inherited genetic programming and environmental factors that collectively shape organ development and function in the new offspring. One such factor are the indigenous microbiota and their interactions with the host. READ MORE

  4. 12. Immune regulation during pregnancy in relation to allergy and in women undergoing in vitro fertilization

    Author : Marie Persson; Maria Jenmalm; Göran Berg; Christina Ekerfelt; Lucia Mincheva-Nilsson; Linköpings universitet; []
    Keywords : ;

    Abstract : During pregnancy, the fetus expresses both maternal and paternal antigens. To the mother, the paternal antigens are foreign, providing her immune system with an interesting challenge. The fact that the fetus is not normally attacked and rejected implies that mechanisms of tolerance must exist. READ MORE

  5. 13. Reproductive physiology of the female three-spined stickleback, Gasterosteus aculeatus

    Author : Chrysoula Roufidou; Bertil Borg; Geir Lasse Taranger; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 15. Fewer kids not always by choice : the link between endocrine-disrupting chemicals and female reproductive health

    Author : Richelle Duque Björvang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Fertility rates are declining from five children per woman in the 1950s to less than three children per woman in 2019. While this is partly due to women choosing to have fewer kids, there are growing evidence that endocrine-disrupting chemicals (EDCs) in the environment may play a role in this phenomenon. READ MORE
