  1. 1. Endothelin and the regulation of peripheral and uteroplacental vascular tone during pregnancy

    Författare :Gunilla Ajne; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Endothelin; pregnancy; uteroplacental blood flow; peripheral resistance; endothelin receptors;

    Sammanfattning : The mechanism behind the vascular adaptation during pregnancy is poorly understood. The fall in peripheral resistance, particularly in the uterine vasculature, is crucial for sufficient increase in uteroplacental blood flow and thereby for normal fetal growth and development.

  3. 2. Regulation of vascular tone in myometrial resistance arteries in normal pregnancy and preeclampsia

    Författare :Karolina Kublickiene; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Atrial natriuretic peptide; Blood vessels; Endothelin-l; Endothelin receptors; Myogenic tone; Myometrial Arteries; Preeclampsia; Pregnancy; Nitric oxide; Shear stress; Vascular endothelium; Vascular smooth muscle .;

    Sammanfattning : Background: Normal pregnancy is characterized by the occurrence of substantial vasodilatation. Pressure responsiveness and vascular reactivity to administered vasoconstrictors undergo considerable attenuation. These circulatory changes are essential to maintain adequate oxygen and nutrient delivery to the placenta and thus to the fetus. LÄS MER

  4. 3. Endothelin and nitric oxide in the fetoplacental circulation

    Författare :Anna Sand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Fetoplacental circulation; placental arteries; endothelin-1; nitric oxide; potassium channels; M-CSF; endothelin receptors; BKCa; ETA; ETB;

    Sammanfattning : Background: Normal fetal growth and development depend on a satisfactory uteroplacental and fetoplacental blood flow. This will ensure an adequate gaseous exchange and nutritional supply to the fetus. LÄS MER

  5. 4. Small artery dysfunction : focus on preeclampsia and end-stage renal disease

    Författare :Natallia Luksha; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :resistance arteries;

    Sammanfattning : Background: End-stage renal disease (ESRD) and preeclampsia (PE) are associated with high risk of cardiovascular events and characterized by endothelial dysfunction. Resistance arteries are actively involved in the control of blood pressure and blood flow to the target organs. LÄS MER

  7. 5. Vascular mechanical properties and endothelial function with special reference to pregnancy and hormonal influences

    Författare :Jana Brodszki; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gynaecology; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; Obstetrics; systemic lupus erythematosus; hormone therapy; preeclampsia; pregnancy; endothelial function; arterial stiffness; vessels; ultrasound; cardiovascular disease;

    Sammanfattning : Cardiovascular disease (CVD) is one of the leading causes of mortality and morbidity. Early recognition of vascular changes, both structural and functional, may help to identify individuals at risk for CVD. LÄS MER
