متن کاملUterine artery Doppler velocimetry , calcium and lipids in pregnant women of advanced age
Women of advanced maternal age are considered to be at a substantially increased risk of spontaneous abortion. The increased spontaneous abortion rate in older women rnight be associated with a defective vascular response to placentation, which rnight lead to fetal ischaemia and fetal dead. Doppler velocirnetry of the uterine artery allows non-invasive assessment of uteroplacental hemodynamics....
متن کاملDifferent changes in resistance index between uterine artery and uterine radial artery during early pregnancy.
BACKGROUND Changes in blood flow impedance of the uterine artery (UA) and uterine radial artery (RA) which is in the lower-extremity of the UA were examined during early pregnancy. METHODS Blood flow impedance was assessed by transvaginal color-pulsed-Doppler-ultrasonography in 72 women from weeks 4-16 of pregnancy and expressed as a resistance index (RI). RESULTS RA-RI remained at the late...
متن کاملHeme oxygenase-1 is critically involved in placentation, spiral artery remodeling, and blood pressure regulation during murine pregnancy
The onset of pregnancy implies the appearance of a new organ, the placenta. One main function of the placenta is to supply oxygen to the fetus via hemoproteins. In this review, we highlight the importance of the enzyme heme oxygenase-1 (HO-1) for pregnancy to be established and maintained. HO-1 expression is pivotal to promote placental function and fetal development, thus determining the succe...
متن کاملNon-invasive placentation in the marsupials Macropus eugenii (Macropodidae) and Trichosurus vulpecula (Phalangeridae) involves redistribution of uterine Desmoglein-2.
In mammalian pregnancy, the uterus is remodeled to become receptive to embryonic implantation. Since non-invasive placentation in marsupials is likely derived from invasive placentation, and is underpinned by intra-uterine conflict between mother and embryo, species with non-invasive placentation may employ a variety of molecular mechanisms to maintain an intact uterine epithelium and to preven...
