  1. 1. Studies on Prostanoid Production in the Umbilicoplacental Circulation

    Författare :Pia Saldeen; Malmö Reproduktionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gynaecology; Obstetrics; Umbilical; Thromboxane; Pulsatility Index; Prostacyclin; Pregnancy; Placenta; Peroxidation; Growth restriction; Endoperoxides; Endothelium; Doppler; Diabetes; sexualitet; reproduktion; andrologi; gynekologi; andrology; reproduction; sexuality; Obstetrik;

    Sammanfattning : The fetoplacental circulation is a low pressure system with a high vascular prostacyclin to thromboxane (Pc/Tx)synthesis ratio. In intrauterin growth restriction (IUGR) and diabetes the prostanoid balance may be altered. LÄS MER

  3. 2. Studies on Human Endogenous Retroviruses (HERVs) with Special Focus on ERV3

    Författare :Ann-Catrin Andersson; Bengt Widegren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; human endogenous retroviruses; HERV; ERV3; expression; in situ hybridisation; real-time PCR; U-937; retinoic acid.; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : Human endogenous retroviruses (HERVs) represent approximately 7% of the human genome. This investigation was focused on one particular HERV, ERV3, with the main purpose of characterising its gene expression patterns and genomic distribution of ERV3-like sequences. LÄS MER

  4. 3. Placental pathology regarding inflammation and a new classification of stillbirth

    Författare :Ingela Hulthén Varli; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: The incidence of stillbirth has remained almost constant during the last 2-3 decades despite obvious improvements in obstetric care. To achieve a reduction of stillbirth, better understanding of the etiology is imperative. Relevant test protocols and audit work is reported to reduce the number of unexplained cases. LÄS MER

  5. 4. Placental histopathology in preeclampsia and outcome of the offspring

    Författare :Marie-Therese Vinnars; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Preeclampsia (PE) is a major cause of maternal and fetal morbidity and mortality. The maternal symptoms are diverse and the neonates are often born premature and growth-restricted. Today the survival of premature infants has increased, but the neonatal complications including morbidity and long-term developmental deficits are still common. LÄS MER

  7. 5. Molecular Mechanisms Underlying Abnormal Placentation in the Mouse

    Författare :Yang Yu; Reinald H. Fundele; Rolf Ohlsson; J. GRAHAM BURTON; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; IUGR; Placental phenotype; Placental hyperplasia; Diabetes; IHPD; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : Placental development can be disturbed by various factors, such as mutation of specific genes or maternal diabetes. Our previous work on interspecies hybrid placental dysplasia (IHPD) and two additional models of placental hyperplasia, cloned mice and Esx1 mutants, showed that many genes are deregulated in placental dysplasia.
