  1. 16. Effects of excess glucocorticoids on neural cell fate : long lasting consequences of adverse prenatal factors

    Författare :Mirko Conti; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The developing nervous system is particularly vulnerable to high level of glucocorticoids (GCs). Excess GCs is often associated with decreased birth weight in relation to gestational age, and to increased risk of psychiatric disorders, like depression, later in life. LÄS MER

  3. 17. Expression and regulation of water channels and ion transporters : ontogenic aspects

    Författare :Masato Yasui; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :water balance; developmental gene expression regulation; gene transcription; fetal lung fluid; urinary concentrating capacity; hormonal regulation;

    Sammanfattning : The content and distribution of body water changes dramatically during the perinatal period and in infancy. Transport of water across the cell membrane occurs via diffusion and via specific water channels. Transport via water channels is fast and may be hormonally regulated. LÄS MER

  4. 18. Temporal monitoring of intracellular Ca2+ signaling and origins of Ca2+ oscillations

    Författare :Dominic-Luc Webb; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis examined parameters influencing stimulated cytoplasmic free Ca2+ concentration ([Ca2+]i) oscillations in hepatocytes and pancreatic beta-cells. Hepatic glucose output is regulated in part by hormones such as vasopressin that act through [Ca 2+]i oscillations. LÄS MER

  5. 19. Pathophysiology of critically ill covid-19 patients

    Författare :Susanne Rysz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : With the onset of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, a new disease, COVID-19, challenged health care professionals and scientists. The angiotensin-converting enzyme type 2 (ACE2) was identified early in the pandemic as being the receptor used by SARS-CoV-2 for cell entrance. LÄS MER
