SPARCL1 and NT‐proBNP as biomarkers of right ventricular‐to‐pulmonary artery uncoupling in pulmonary hypertension

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1416-1426, April 2025.
Abstract Aims SPARCL1 was recently identified as a biomarker of right ventricular (RV) maladaptation in patients with pulmonary hypertension (PH), and N‐terminal pro‐brain natriuretic protein (NT‐proBNP) is an established biomarker of RV failure in PH. The present study investigated whether NT‐proBNP and SPARCL1 concentrations are associated with load ...

Aberrant methylation of placental development genes in chorionic villi of spontaneous abortions with trisomy 16

open access: yesВавиловский журнал генетики и селекции
In humans, aneuploidy is incompatible with the birth of healthy children and mainly leads to the death of embryos in the early stages of development in the first trimester of pregnancy.

Vascular Remodeling and Extracellular Matrix Breakdown in the Uterine Spiral Arteries During Pregnancy

open access: yesReproductive Sciences, 2007
During pregnancy, trophoblasts invade and transform the maternal spiral arteries that supply blood to the placenta. Recent work has revealed that this process occurs in several stages, and details of the molecular and cellular mechanisms are beginning to emerge, including changes that precede or accompany trophoblastic colonization of the vascular ...

Laminins Regulate Placentation and Pre-eclampsia: Focus on Trophoblasts and Endothelial Cells

open access: yesFrontiers in Cell and Developmental Biology, 2020
Pre-eclampsia is a systemic vascular disease characterized by new-onset hypertension and/or proteinuria at ≥20 weeks of gestation and leads to high rates of maternal and perinatal morbidity and mortality.

Influence of relative NK-DC abundance on placentation and its relation to epigenetic programming in the offspring [PDF]

open access: yes, 2014
Normal placentation relies on an efficient maternal adaptation to pregnancy. Within the decidua, natural killer (NK) cells and dendritic cells (DC) have a critical role in modulating angiogenesis and decidualization associated with pregnancy.

Prevention of stillbirths associated with umbilical cord abnormalities: A clinico‐pathological overview

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Stillbirths affect millions of pregnancies every year worldwide, and obstruction of the umbilical cord blood flow is one of the main causes of fetal death. This review provides a clinico‐pathological overview of cord abnormalities potentially associated with antepartum stillbirth, describing the mechanism determining the death and addressing ...

Assessment of Maternal Vascular Remodeling During Pregnancy in the Mouse Uterus. [PDF]

open access: yes, 2015
The placenta mediates the exchange of factors such as gases and nutrients between mother and fetus and has specific demands for supply of blood from the maternal circulation.
