  1. 1. Placental Function : An Epidemiological and Magnetic Resonance Study

    Författare :Sara Sohlberg; Anna-Karin Wikstrom; Matts Olovsson; Ajlana Mulic-Lutvica; Johan Wikström; Karel Marsal; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; body height; body mass index; early preeclampsia; late preeclampsia; magnetic resonance imaging; placenta; perfusion; IVIM; risk factors; energy metabolism; magnetic resonance spectroscopy; 31P-MRS; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Placental function is central for normal pregnancy and in many of the major pregnancy disorders. We used magnetic resonance imaging techniques to investigate placental function in normal pregnancy, in early and late preeclampsia and in intrauterine growth restriction. LÄS MER

  3. 2. Epidemiological Studies of Preeclampsia : Maternal & Offspring Perspectives 

    Författare :Jóhanna Gunnarsdóttir; Anna-Karin Wikström; Sven Cnattingius; Ulf Högberg; Alexander Smárason; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Placental dysfunction; blood pressure; small-for-gestational-age; fetal growth restriction; intrauterine; prenatal exposure; postnatal height gain; linear growth;

    Sammanfattning : Preeclampsia is a placental-related disorder characterized by generalized endothelial activation. Vascular predisposition is associated with the occurrence of preeclampsia and the recurrence risk is substantial. LÄS MER

  4. 3. Experimental and Clinical Studies of Oxidative Stress in Pre-Eclampsia

    Författare :Peppi Nash; Ulf Eriksson; Matts Olovsson; Leif Jansson; Lucilla Poston; Uppsala universitet; []
    Nyckelord :Obstetrics and gynaecology; Pre-eclampsia; Oxidative stress; Diabetes; Placenta; Rat; Antioxidants; Suramin; Vitamin E; Vitamin C; PAI-1; PAI-2; Obstetrik och kvinnosjukdomar;

    Sammanfattning : Impaired placentation and oxidative stress are proposed to play major roles in the pathogenesis of pre-eclampsia (PE). It has recently been pointed out that PE might be more than one disease and may have several different pathogeneses. LÄS MER

  5. 4. Investigating the source of free fetal hemoglobin in preeclampsia. The role of the placenta and the fetus

    Författare :Zahra Masoumi; Lund Obstetrik och gynekologi; []
    Nyckelord :Preeclampsia pregnancy; Placenta; Umbilical cord blood; Fetal erythropoiesis; Non-erythroid globin;

    Sammanfattning : Preeclampsia (PE) is an important pregnancy complication that affects 3-8% of women worldwide and is a leading cause of maternal and fetal morbidity and mortality. It is known that PE is associated with placental dysfunction, resulting in hypoxia, oxidative stress, altered metabolism and production of inflammatory cytokines. LÄS MER

  7. 5. Hypercoagulation in preeclampsia : implications for maternal health and fetal growth

    Författare :Shu He; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Preeclampsia (PE) is a serious complication of pregnancy characterized by hypertension, proteinuria, oedema and hypercoagulation. Damage in organs, such as the liver and kidney, is harmful to the maternal health. Impairments in placental function cause intrauterine growth retardation (IUGR). LÄS MER
