The placenta serves, in part, as a barrier to exclude noxious substances from the fetus. In humans, a single-layered syncytium of polarized trophoblast cells and the fetal capillary endothelium separate the maternal and fetal circulations. P-glycoprotein is present in the syncytiotrophoblast throughout gestation, consistent with a protective role that(More)
Nitric oxide synthase (NOS) is responsible for the biological production of nitric oxide (NO) in several organs. NOS activity has also been localized in the reproductive tract, although direct evidence for its presence in the human or bovine oviduct is still lacking. In the present study, four different techniques were used to identify the presence of NOS(More)
Opiate addiction has been widely documented to have negative impact on pregnancy course and outcome. Unfavorable psychosocial situation of addicted women predispose for poor processing of the physiological and psychological demands of pregnancy. Thus aim of our study was to investigate the psychological mood state of opiate addicts during pregnancy and(More)
OBJECTIVE To study the effect of elective Cesarean section and zidovudine prophylaxis on vertical HIV transmission. DESIGN Prospective study. SETTING Obstetric and paediatric clinics in Switzerland. PARTICIPANTS Children of mothers with HIV infection identified before or at delivery. INTERVENTIONS Routine use of elective Cesarean section for(More)
There is a heterogeneous population of young women with cardiovascular disease contemplating pregnancy. Many of the conditions are rare and require teams with expertise in the management of such patients. A specific congenital or acquired cardiovascular anomaly and its physiology must be understood. The nature of prior surgical procedures and the residua(More)
In bovine oviduct cells 17beta-oestradiol can induce the synthesis of leukaemia inhibitory factor (LIF), a glycoprotein essential for embryo implantation. Therefore substances which are structurally similar to 17beta-oestradiol and possess oestrogenic activity may also modulate LIF synthesis and influence the reproductive process. We used primary cultures(More)
BACKGROUND Although methadone maintenance is the standard treatment of opiate addiction in pregnancy, opinion as to its utility is divided. The aim of this study was to analyze polydrug abuse, pregnancy outcome and fetomaternal complications among pregnant women in a major Swiss methadone maintenance program. METHODS Prospective data collection of all(More)
We evaluated the impact of maternal drug abuse at term on human placental cytochrome P450 (CYP)-mediated (Phase I) xenobiotic and steroid-metabolizing activities [aromatase, 7-ethoxyresorufin O-deethylase (EROD), 7-ethoxycoumarin O-deethylase (ECOD), pyrene 1-hydroxylase (P1OH), and testosterone hydroxylase], and androstenedione-forming isomerase, NADPH(More)
BACKGROUND Maternal cocaine abuse in pregnancy is associated with complications such as intrauterine growth retardation, abruptio placentae, and preterm delivery. CASE We report what is, to our knowledge, the first published observation of fetal bilateral renal agenesis associated with a vascular disruption syndrome comprising upper limb reduction defect(More)
