Background: Preeclampsia is a heterogeneous disorder affecting different body systems and frequently associated with morbidity and mortality. Early preeclampsia prediction will reduce this associated morbidity and mortality as it will give the chance for frequent maternal and fetal surveillance and application of prophylactic procedures. Objective: The aim of this work is to evaluate the role of mean pulsatility index (PI) of the uterine arteries and maternal serum concentrations of pregnancy-associated plasma protein A (PAPP-A) and placental growth factor (PlGF) in early preeclampsia prediction in primigravida...

OBJECTIVE: Soluble Fms-like tyrosine kinase-1 (sFlt-1) is thought to be causative in the pathogenesis of preeclampsia (PE) and specific removal of sFlt-1 via dextran sulfate cellulose (DSC)-apheresis was suggested as cure to allow prolongation of pregnancy in preterm PE. However, in addition a deranged lipoprotein metabolism may impact endothelial and placental function in PE. Lipoprotein-apheresis by heparin-mediated extracorporeal LDL-precipitation (H.E.L.P.) was previously applied and has been shown to alleviate symptoms in PE...

BACKGROUND: At-risk small-for-gestational age (SGA) pregnancies in New Zealand are identified using Doppler ultrasound; fetuses with Doppler abnormalities are considered growth restricted (FGR). Low maternal placental growth factor (PlGF) has also been associated with late-onset FGR. AIMS: To investigate whether low PlGF at diagnosis of late-onset SGA identifies the same fetuses classified FGR by detailed Doppler studies, and the association between low PlGF and adverse pregnancy outcomes...

In the western world, pre-eclampsia, diagnosed in 3-5% of pregnant women, is a major cause of maternal and fetal morbidity and mortality. Once pre-eclampsia is diagnosed, the only effective treatment is delivery. There are known historical risk factors for the development of pre-eclampsia, however only 30% of the women who will develop pre-eclampsia are identified based on their presence. Recently, new first trimester algorithms for the prediction of pre-eclampsia were developed, based on the observation that pregnant women who develop pre-eclampsia have imbalanced placental angiogenic factors and that failure of the trophoblastic migration may change the flow in the uterine arteries...

Pericyte desorption from retinal blood vessels and subsequent vascular abnormalities are the pathogenesis of diabetic retinopathy (DR). Although the involvement of abnormal signals including platelet-derived growth factor receptor-β (PDGFRβ) and vascular endothelial growth factor-A (VEGF-A) have been hypothesized in DR, the mechanisms that underlie this processes are largely unknown. Here, novel retinopathy mouse model (N-PRβ-KO) was developed with conditional Pdgfrb gene deletion by Nestin promoter-driven Cre recombinase (Nestin-Cre) consistently reproduced through early non-proliferative to late proliferative DR pathologies...

Preeclampsia is reported in pregnant women around the world and often causes maternal/fetal mortality and morbidity. In the current study, we assessed the efficacy of celastrol on a rat preeclampsia model induced by Nω -nitro-L-arginine methyl ester hydrochloride (L-NAME). Pregnant rats were administered L-NAME to establish preeclampsia. A total of 48 animals were randomly assigned into 4 groups (n = 12 each): control, control plus celastrol treatment (control+celastrol), preeclampsia, and preeclampsia plus celastrol...

Preeclampsia has been shown to be associated with changes in cerebral structure and cognitive function later in life. Nf (neurofilaments) are specific scaffolding proteins of neurons, and their quantification in serum has been proposed as a biomarker for neuroaxonal injury. We performed a prospective, longitudinal, single-center study at the University Hospital of Basel to determine serum Nf concentrations in pregnant women with singleton pregnancies and with high risk of preeclampsia or with early signs of preeclampsia...
