Placental invasiveness-the number of maternal tissue layers separating fetal tissues from maternal blood-is variable across mammalian species. Although this diversity is likely to be functionally important, variation in placental invasiveness remains unexplained. Here we test the hypothesis that increased risk of transplacental transmission of pathogens from the mother to the fetus promotes the...

OBJECTIVES To investigate whether the addition of maternal serum placental growth factor (PlGF) measured at 11-13 weeks' gestation improves the performance of screening for stillbirths that is achieved by a combination of maternal factors and first-trimester biomarkers such as maternal serum pregnancy-associated plasma protein-A (PAPP-A), fetal ductus venosus pulsatility index for veins (DV-PIV...

Implantation and placentation are critical steps for successful pregnancy. The pig has a non-invasive placenta and the uterine luminal epithelium is intact throughout pregnancy. To better understand the regulation mechanisms in functions of endometrium at three certain gestational stages that are critical for embryo/fetal loss in pigs, we characterized microRNA (miRNA) expression profiles in th...

Introduction: Cette étude dont le but était d'évaluer la contribution de l'électroencéphalogramme (EEG) en neurologie pédiatrique et de déterminer les indications pertinentes chez l'enfant de 0 à 15ans. Méthodes: Il s'agit d'une étude rétrospective et descriptive réalisée au laboratoire d'électroencéphalographie de l'Hôpital Gynéco-Obstétrique et Pédiatrique de Yaoundé du 1er novembre 2011 au 1...

Poor placentation, which manifests as pre-eclampsia and fetal growth restriction, is a major pregnancy complication. The underlying cause is a deficiency in normal trophoblast invasion of the spiral arteries, associated with placental inflammation, oxidative stress, and an antiangiogenic state. Peripartum therapies, such as prenatal maternal corticosteroids and magnesium sulphate, can prevent s...

BACKGROUND The physiopathology of Preeclampsia (PE) is characterized by a deficiency in the process of placentation, systemic endothelial dysfunction and Central Nervous System (CNS) hyperflow. From a clinical point of view, it would be interesting to determine the occurrence of these phenomena before the onset of clinical manifestations of the disease, raising the possibility of new methods fo...
