    Detta är en avhandling från Uppsala : Institutionen för arkeologi och antik historia

    Författare :Anne Ingvarsson-Sundström; Uppsala universitet.; [2003]
    Nyckelord :HUMANIORA; HUMANITIES; Classical archaeology and ancient history; children; archaeology; osteology; Asine; Lerna; Middle Helladic; skeletons; age; subadults; graves; growth; health; weaning; mortality; fetuses; infants; mortuary ritual; Bronze Age.; Antikens kultur och samhällsliv; HUMANITIES and RELIGION History and philosophy subjects Historical cultures Classical archaeology and ancient history; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Historiska kulturer Antikens kultur och samhälle; arkeologi; Archaeology;

    Sammanfattning : This study focusses on children’s living conditions during the Middle Helladic period in Greece. The primary material comprises disarticulated skeletal remains found in a stratigraphic context during the Swedish excavations of Asine in 1926: 4,583 fragments/complete bones. LÄS MER

  2. 2. Brain-sparing Circulation in Growth-restricted Human Fetuses

    Detta är en avhandling från Department of Obstetrics and Gynecology, Lund University

    Författare :Jing Fu; Lund University.; Lunds universitet.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics; gynaecology; andrology; reproduction; sexuality; Fetal growth-restriction.; Brain-sparing.; Oxytocin challenge test.; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Sammanfattning : The aim of the studies was to explore fetal circulatory changes relative to development of brain-sparing flow (BSF) in growth-restricted fetuses exposed to acute hypoxic stress, as provoked by uterine contractions during an oxytocin challenge test (OCT).(1) In fetuses with a normal cerebral circulation during basal conditions, signs of an acute hyperperfusion in both the arterial and venous cerebral vascular systems were demonstrated in response to acute hypoxic stress; (2) Fetuses with an already established BSF showed no further ability of brain-sparing during acute hypoxic stress; (3) In venous cerebral vessels of fetuses with established BSF, the flow responses to hypoxic stress were equivocal, indicating different reactions in areas drained by different veins, or a deranged physiological vascular response; (4) Blood flow changes occurred synchronized in the middle and anterior cerebral arteries when fetuses with an intact cerebral circulation were exposed to hypoxic stress; (5) When fetuses with an established BSF showed no further changes in the middle cerebral artery, no changes were found in the anterior cerebral artery either.

  3. 3. Ultrasound prediction of large fetuses. Epidemiological and clinical investigations

    Detta är en avhandling från Department of Obstetrics and Gynecology, Lund University

    Författare :Gun Lindell; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Two-dimensional ultrasound; three-dimensional ultrasound; fetus; intrauterine growth; maternal characteristic; large-for-gestational age; antenatal calculation; Bayesian theorem; fetal weight; estimation; post-term fetus; fetal macrosomia;

    Sammanfattning : The proportions of newborns with a birth weight (BW) >4,000 g and of macrosomic newborns (BW >4,500 g) have increased during the last two decades, parallel with an increasing maternal pre-pregnancy body mass index (BMI) and age at the time for pregnancy. Delivery of a large fetus, especially >4,500 g might cause perinatal complications for both the mother and her child. LÄS MER

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

    Detta är en avhandling från Department of Obstetrics and Gynecology, Lund University

    Författare :Edgar Hernandez-Andrade; Lund University.; Lunds universitet.; [2003]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 5. Ultrasound as predictor of perinatal outcome

    Detta är en avhandling från Department of Clinical Sciences, Lund University

    Författare :Gisela Ghosh; Lund University.; Lunds universitet.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Doppler; Ultrasound; fetus; amniotic fluid index; nuchal cord; uterine artery; umbilical vein; fetal growth restriction; umbilical artery; pulsation; pregnancy;

    Sammanfattning : The aim of the work described in this thesis was to evaluate the value of ultrasound examinations of the amniotic fluid, umbilical cord and blood flow velocity waveform of the fetal and placental vessels as predictors of the perinatal outcome. In the first study, the amniotic fluid index (AFI) measured on admission to the labour ward was evaluated in low-risk pregnancies. LÄS MER
