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 …

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: 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 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 …

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 …

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 …

To investigate the physiological changes of leptin levels and whether placenta is linked to its
production during pregnancy, plasma of 65 pregnant women at various gestational weeks …

The present study was carried out to investigate leptin levels in arterial and venous cord
serum and in amniotic fluid in full-term infants at birth and on the 5th postnatal day to define …

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 …

AIMS: To verify if plasma leptin concentrations of newborns at birth differ significantly
between sexes; and to investigate the potential interactions between plasma leptin and …
