Melatonin and vitamin C increase umbilical blood flow via nitric oxide-dependent mechanisms
(2010)
Inadequate umbilical blood flow leads to intrauterine growth restriction, a major killer in perinatal medicine today. Nitric oxide (NO) is important in the maintenance of umbilical blood flow, and antioxidants increase NO ...
Reverse flow in the umbilical vein in a case of trisomy 9
(Blackwell Science Ltd, 2000-11-01)
This report describes a case of reverse flow in the umbilical vein and ductus venosus during atrial contraction of a fetus at 12 weeks of gestation with increased nuchal translucency (9.1 mm). in addition, Doppler velocimetry ...

Effects of clamping umbilical cord on the neonatal viability of puppies delivered by cesarean section
(2020-01-01)
In human neonates, when the umbilical cord is kept intact postpartum, blood continues to flow to the neonate, but this procedure might be difficult in dogs owing to a shorter umbilical cord and several neonates in a litter. ...
Dopplervelocimetria no Rastreamento de Aneuploidias no Primeiro Trimestre da Gestação
(Federação Brasileira das Sociedades de Ginecologia e Obstetrícia, 2001-06-01)
Objective: to study the value of Doppler velocimetry of the ductus venosus and of the umbilical artery and vein, in the screening for chromosomal abnormalities at 10-14 weeks of gestation. Patients and Methods: a total of ...
Avaliação imunofenotípica de subpopulações linfocitárias no sangue do cordão umbilical e periférico de suínos neonatos (Sus scrofa)
(Colégio Brasileiro de Patologia Animal - CBPA, 2014-04-01)
Considering the importance of umbilical cord blood as a potential source of stem cell and, on the other hand, the use of the domestic swine (Sus scrofa) as a useful model for biomedical research in regenerative medicine ...
Fetal venous Doppler in pregnancies with placental dysfunction and correlation with pH at birth
(INFORMA HEALTHCARELONDON, 2013-08-02)
Objectives: To determine the correlation between ph at birth and venous Doppler parameters in pregnancies with placental dysfunction. Methods: This was a prospective cohort study of 58 pregnancies with the diagnosis of ...
Umbilical artery half peak systolic velocity deceleration time throughout pregnancy and its role in fetuses with bradycardia
(John Wiley, 2007)
Objectives To describe a new technique for Doppler
waveform quantification of the fetal umbilical artery,
the half peak systolic velocity (h-PSV) deceleration time,
which measures the time that it takes a single flow ...
Transient fetal blood redistribution associated with maternal supine position
(Walter De Gruyter Gmbh, 2017)
Objective: To investigate whether fetal blood circulation is influenced by the maternal supine position. Methods: The inclusion criteria were good health, a singleton pregnancy, maternal age between 18 and 40 years, ...
