The secretion pattern of ApN in normal and complicated pregnancies strongly suggests an involvement of ApN in insulin resistance during gestation, while resistin seems to have a minor role. Moreover, the detection of high levels of resistin and ApN in cord blood during gestation is consistent with a regulatory action of these adipokines on tissue differentiation and foetal growth.

In human pregnancy, the fetal glucose concentration is a function of both gestational age and the maternal glucose concentration. In FGR pregnancies, as an accommodation of the fetus to a restricted placental size and placental glucose transport capacity, the maternal-fetal glucose concentration difference is increased, and this increase is a function of the clinical severity.

The present section describes an algorithm for the digital signal processing aimed at the detection of maternal and fetal QRS complexes from the abdominal ECG lead.The research described in here is connected to an extensive clinical experience of fetal QRS morphology studies described in [16]. 20 healthy pregnant women after the 25th week of gestation were considered in clinostatic, resting condition at the Department of Obstetrics and Gynecology "L. then stored on a DEC-VAX 750 computer for which all processing and graphic programs have been developed. 2. a(t) is then filtered with a derivative and low-pass FIR digital filter (128 coefficients, Weber-Cappellini window, 20 Hz cutoff frequency). Such a filter accentuates the occurrence of MQRS's, whose maxima are singled out on a(t).
