Drug transfer and metabolism by the human placenta
MR Syme, JW Paxton, JA Keelan - Clinical pharmacokinetics, 2004 - Springer
The major function of the placenta is to transfer nutrients and oxygen from the mother to the
foetus and to assist in the removal of waste products from the foetus to the mother. In addition…

[HTML][HTML] The not-so-sterile womb: evidence that the human fetus is exposed to bacteria prior to birth
The human microbiome includes trillions of bacteria, many of which play a vital role in host
physiology. Numerous studies have now detected bacterial DNA in first-pass meconium and …

Independent regulation of apical and basolateral drug transporter expression and function in placental trophoblasts by cytokines, steroids, and growth factors
DA Evseenko, JW Paxton, JA Keelan - Drug Metabolism and Disposition, 2007 - ASPET
Placental ATP binding cassette (ABC) transporters protect placental and fetal tissues by
effluxing xenobiotics and endogenous metabolites. We have investigated the effects of cytokines …

[HTML][HTML] A critical review of the bacterial baptism hypothesis and the impact of cesarean delivery on the infant microbiome
Numerous studies suggest that infants delivered by cesarean section are at a greater risk of
non-communicable diseases than their vaginal counterparts. In particular, epidemiological …

Prenatal testosterone exposure is related to sexually dimorphic facial morphology in adulthood
Prenatal testosterone may have a powerful masculinizing effect on postnatal physical
characteristics. However, no study has directly tested this hypothesis. Here, we report a 20-year …

Planting the seed: origins, composition, and postnatal health significance of the fetal gastrointestinal microbiota
It has long been assumed that establishment of the fetal microbiome commences with the
birthing process. However, recent studies have found bacterial DNA in umbilical cord blood, …

[HTML][HTML] Strategies to prevent preterm birth
After several decades of research, we now have evidence that at least six interventions are
suitable for immediate use in contemporary clinical practice within high-resource settings and …

Intrauterine inflammatory activation, functional progesterone withdrawal, and the timing of term and preterm birth
JA Keelan - Journal of Reproductive Immunology, 2018 - Elsevier
The central role of inflammatory processes in labour and delivery is now well-recognised.
However, the biomolecular, immunological and endocrine mechanisms involved in the labour …
