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 …

BACKGROUND AND AIMS Leptin, the ob gene product, plays a key role in the regulation of
body fat mass and weight in adult life. The mechanisms by which maternal 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 …

Objective: To evaluate leptin values in placental cord blood of newborns with normal
intrauterine growth after 30–42 weeks of gestation. Design: Leptin, a protein encoded by the …

To investigate leptin and to which factors it is related during the perinatal period, we
measured serum leptin levels of 46 mothers at delivery, umbilical cord blood and infants on …

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 …

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 …

The aim of this study was to investigate the ontogeny of serum leptin concentrations during
the second half of gestation and at birth in small for gestational age and normal fetuses and …

Sex-based differences in serum leptin concentrations have been reported in adolescence
and adulthood. To discover when such differences were generated, serum leptin …

BACKGROUND: Leptin is secreted from adipose tissue and plays an important role in
obesity. Recent studies have shown that the relationship between leptin and body fat mass …
