OBJECTIVE The aim of this study was to assess fetal urinary production rates (FUPR) in twin gestations using 3D ultrasonography with VOCAL® (virtual organ computer-aided analysis) and to develop a curve of normal values for the target population. METHODS A cross-sectional study was performed in 30 normal twin pregnancies with gestational ages ranging from 20 to 34 weeks. FUPR was measured usi...

OBJECTIVE The purpose of the study was to characterize changes in apoptosis and the renin-angiotensin system (RAS) in fetal growth restriction (FGR). MATERIALS AND METHOD Fetuses were collected from patients who visited our hospital to either terminate or abort their pregnancy. Kidneys of fetuses which suffered with FGR, (n=11) at gestational age of 33.4±0.5 weeks and those from non-FGR (n=12...

Using a mid- to late-gestation ovine model of intrauterine growth restriction (IUGR), we examined uteroplacental blood flow and fetal growth during melatonin supplementation as a 2 × 2 factorial design. At day 50 of gestation, 32 ewes were supplemented with 5 mg of melatonin (MEL) or no melatonin (CON) and were allocated to receive 100% [adequate; (ADQ)] or 60% [restricted (RES)] of nutrient re...

OBJECTIVES To present the fetal measurements in relation to the foot length at 10-16 weeks gestation on antenatal ultrasound. MATERIALS AND METHODS We reviewed the fetal measurements in 47 scans performed at 10-16 weeks gestation in women attending routine antenatal care. The fetal measurements and measurement ratios were examined in relation to the foot length. RESULTS The fetal biparietal...
