1. Genetic and epidemiological aspects of implantation defects : Studies on recurrent miscarriage, preeclampsia and oocyte donation
Abstract : Implantation requires complex molecular and cellular events involving coagulation, angiogenesis and immunological processes that need to be well regulated for a pregnancy to establish and progress normally. The overall aim of this thesis was to study different models associated with atypical angiogenesis, impaired implantation and/or placentation, such as recurrent miscarriage (RM), oocyte donation (OD) and preeclampsia.

2. Molecular Mechanisms Underlying Abnormal Placentation in the Mouse
Abstract : Placental development can be disturbed by various factors, such as mutation of specific genes or maternal diabetes. Our previous work on interspecies hybrid placental dysplasia (IHPD) and two additional models of placental hyperplasia, cloned mice and Esx1 mutants, showed that many genes are deregulated in placental dysplasia.

3. Characterizing retained placenta : epidemiology and pathophysiology of a critical obstetric disorder
Abstract : Background: Retained placenta is associated with severe postpartum hemorrhage but its etiology and pathophysiology are largely unknown. Certain studies have suggested that retained placenta is associated to defective placentation disorders- pregnancy disorders with an initial defective placentation resulting in increased oxidative stress.

4. New Functions for Old Genes in the Mouse Placenta
Abstract : Different species are separated by pre-zygotic reproductive barriers which impede gene flow between them. Rarely, when pre-zygotic barriers break down, interspecific hybrids are produced that display abnormal phenotypes, collectively called hybrid dysgenesis effects. READ MORE

5. Cytokines and immune balance in preeclampsia : a survey of some immunological variables and methods in the study of preeclampsia
Abstract : Preeclampsia is one of the most feared pregnancy complications, with a risk of maternal and fetal death and with no ideal therapy readily available. The cause of this strictly pregnancyrelated disease is still unknown and is therefore a great challenge to all researchers in the field of pregnancy-related pathophysiology. READ MORE
