    Sammanfattning : During pregnancy, 4 - 7% of women suffer from major depressive disorder. When antidepressive treatment is needed, selective serotonin reuptake inhibitors (SSRIs) are the most commonly used. Although severe complications from SSRI treatment are rare, association with a number of adverse pregnancy and fetal outcomes has been found. LÄS MER

  3. 2. Spatiotemporal Profiling of Human Development Using Multiplexed Imaging

    Författare :Sanem Sariyar; Emma Käller Lundberg; Burcu Ayoglu; Gunilla Westergren-Thorsson; KTH; []

    Sammanfattning : Human development is complex and intricate, where the positions of cells, expression of key markers, and cell-cell interactions contribute to the development of various organs from different germ layers and the establishment of the body axis. Therefore, understanding human development within spatial and temporal aspects is crucial. LÄS MER

  4. 3. Studies on in vitro fertilised human preembryos. Morphological and chromosomal aspects

    Författare :Thorir Hardarson; Göteborgs universitet; []
    Nyckelord :IVF; oocyte; embryo; blastocyst; human; FISH; aneuploidy;

    Sammanfattning : The success rate of in vitro fertilisation (IVF) has gradually increased due to basic research in preembryonic biology and the introduction of new methods, both technical and medical. However, further research is needed to establish which preembryos are developmentally most competent in order to be able to maintain the pregnancy rate while only a single preembryo is being transferred.

  5. 4. The Histidine-rich Glycoprotein in Reproduction

    Författare :Karin E Lindgren; Inger Sundström-Poromaa; Helena Åkerud; Eva Wiberg-Itzel; Lalit Kumar Parameswaran Grace; Uppsala universitet; []

    Sammanfattning : Infertility affects 15% of reproductive-aged couples. The milieu surrounding the growing embryo is of outmost importance, and should be optimised during in vitro fertilisation (IVF). Many biological processes, such as angiogenesis, coagulation, and immune processes need to be well regulated for a pregnancy to occur and progress normally. LÄS MER

  7. 5. Genetic Sex Differences in Early Human Neuronal Development : An Investigation in Embryo Tissue and Embryonic Stem Cells

    Författare :Philipp Pottmeier; Elena Jazin; Armin Raznahan; Uppsala universitet; []

    Sammanfattning : Sex differences in the human body affect many different organs and tissues, some of them have an effect on the human brain and its development. In the developing nervous system, sex differences can bias the number or functionality of neurons, glial cells or synapses. As a result, neural networks might develop with a sex-specific bias. LÄS MER
