OBJECTIVE: To determine the relationships between serum leptin levels in the umbilical
vein (UV) and artery (UA) and the anthropometry of mothers and neonates. STUDY DESIGN …

OBJECTIVE: We investigated the site of leptin production in the fetoplacental circulation.
STUDY DESIGN: We simultaneously determined plasma leptin levels in cord vessels and …

To investigate the physiological significance of umbilical plasma leptin in the fetal growth
and its possible origin of production during pregnancy, plasma leptin concentrations in …

The mechanisms by which maternal and fetal weight are regulated during pregnancy are
poorly understood. The ob protein, termed leptin, is produced by adipocytes. It is involved in …

Sir: The ob protein, termed leptin, is produced by adipocytes and is thought to act as an
afferent satiety signal regulating appetite and weight both in humans and rodents [1-3]. The …

Objective To investigate the relationship between umbilical venous leptin concentration and
gender in 20 pairs of newborns matched 1: 1 for birth weight and gestational age at …

Maternal leptin levels in serum and urine, their relations to maternal weight and body mass
index, were examined in 9 healthy pregnant women from the 12th week of gestation until …

To investigate the effect of leptin on fetal growth, serum leptin concentrations in venous cord
blood were measured in 82 newborns (male= 43, female= 39, gestational age 36–42 weeks …

Objective TO determine whether there is a difference in maternal leptin concentration and
cord blood concentration, consistent with the hypothesis of a noncommunicating, two …

The relationship between in utero fetal growth and fetal leptin concentrations was
investigated between 19 and 41 wk in 40 normal (appropriate for gestational age, AGA) …
