Catestatin-A Potential New Therapeutic Target for Women with Preeclampsia? An Analysis of Maternal Serum Catestatin Levels in Preeclamptic Pregnancies.

Background: Catestatin has been identified as an important factor in blood pressure control in non-pregnant adults. A possible impact on the development of hypertensive disorders of pregnancy has been indicated. Data on catestatin levels in pregnancy are scarce.

Generation of extracellular fluids from first-trimester decidual tissues and their validation by detecting tissue-specific secreted proteins.

The human placenta comes in direct contact with maternal cells and blood at two interfaces. The syncytiotrophoblast layer is surrounded by maternal blood at the intervillous space, and extravillous trophoblasts breach the vascular endothelial cells layer upon spiral artery remodeling and invasion of decidual veins. However, little knowledge exists about EVT-derived secreted factors, which may serve as predictive markers for obstetrical syndromes or shape the local environment at the maternal-fetal interface.

The human placenta shapes the phenotype of decidual macrophages.

During human pregnancy, placenta-derived extravillous trophoblasts (EVTs) invade the decidua and communicate with maternal immune cells. The decidua distinguishes into basalis (decB) and parietalis (decP). The latter remains unaffected by EVT invasion.

Discrimination of coherent and incoherent cathodoluminescence using temporal photon correlations.

We present a method to separate coherent and incoherent contributions of cathodoluminescence (CL) by using a time-resolved coincidence detection scheme. For a proof-of-concept experiment, we generate CL by irradiating an optical multimode fiber with relativistic electrons in a transmission electron microscope. A temporal analysis of the CL reveals a large peak in coincidence counts for small time delays, also known as photon bunching.
