  2. 1. Fractional moving blood volume in fetal organs estimated using power Doppler ultrasound

    Author : Edgar Hernandez-Andrade; Lund Obstetrik och gynekologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; andrology; gynaecology; Obstetrics; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; fetal adrenal gland; fetal lung; radionuclear microspheres; fetal lamb; perfusion; fetus; Power Doppler ultrasound; fractional moving blood volume;

    Abstract : Power Doppler ultrasound (PDU) is a sensitive technique to detect slow blood movement. The aim of the present study was to develop a standardized method for quantification of the PDU signals recorded from a specific region of interest (ROI) within fetal organs. READ MORE

  4. 2. Fetal surveillance and outcome in postterm pregnancy

    Author : Margareta Kitlinski; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; reproduction; andrology; gynaecology; Obstetrics; Ultrasound.; Umbilical cord artery; Prolonged; Postterm; pH; Mortality; Morbidity; Gender; Fetal surveillance; Brain-sparing; Doppler; Blood gases; Acid-base;

    Abstract : To minimize the risk of short-term and long-term morbidity and mortality among children born postterm, studies were performed to evaluate the fetal surveillance program. (1) Male-fetus pregnancies were at an increased risk... READ MORE

  5. 3. Doppler Velocimetry in the Evaluation of Fetal Well-Being

    Author : Mariusz Dubiel; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics; perinatal outcome; physiology; fetus; Doppler velocimetry; Color Doppler Energy; gynaecology; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Abstract : Ultrasound Doppler velocimetry was used to predict fetal well-being. The uterine artery blood velocimetry seemed to be a good predictor of perinatal outcome in high-risk pregnancies and a complement to umbilical artery velocimetry. The fetal middle cerebral artery blood velocimetry might be an early sign of fetal hypoxia. READ MORE

  6. 4. Fetal Outcome in Experimental Diabetic Pregnancy

    Author : Sheller Zabihi; Ulf Eriksson; Michael Welsh; Elisabeth (Lisa) Persson; Uppsala universitet; []
    Keywords : Cell biology; Rat; Mouse; TG; KO; Diabetes in Pregnancy; Embryo; Folic acid; Superoxide dismutase; Catalase; Glutathione peroxidase; Vascular endothelial growth factor-A; Folate binding protein-1; Bax; Bcl-2; Caspase-3; P53; Pax-3; Blood flow; Cellbiologi;

    Abstract : Women with pregestational diabetes have a 2-5 fold increased risk of giving birth to malformed babies compared with non-diabetic women. Diabetes-induced oxidative stress in maternal and embryonic tissues has been implicated in the teratogenic process. READ MORE

  7. 5. Doppler evaluation of coronary blood flow and coronary flow reserve - Clinical and experimental studies

    Author : Gylfi Oskarsson; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Pediatri; Cardiovascular system; Kardiovaskulära systemet; fetal asphyxia; transposition of the great arteries; dilated cardiomyopathy; aortic stenosis; child; neonate; adenosine; coronary flow reserve; Doppler; coronary flow;

    Abstract : Heart diseases in children cause different combinations of myocardial hypertrophy, increased intra-ventricular pressures, volume overload and decreased oxygen saturation. This may affect basal coronary flow and the ability of the heart to maximally increase coronary flow. READ MORE
