Pathological placentation (placenta previa and placenta accreta) is one of the main problems in modern obstetrics, which negatively affects maternal perinatal mortality rates. The use technologies for timely diagnosis this pregnancy complication correct route patient allow to reduce blood loss significantly, save not only life mother child, but also uterus some cases.The objective: evaluate dia...
Invasion of trophoblasts into maternal uterine tissue is essential for establishing mature feto-maternal circulation. The trophoblast invasion associated with placentation is similar to tumor invasion. In this study, we investigated the role of KAI1, an antimetastasis factor, at the maternal-fetal interface during placentation. Mouse embryos were obtained from gestational days 5.5 (E5.5) to E13...
Natural killer (NK) cells are recruited into the uterine stroma during establishment of the hemochorial placenta and are proposed regulators of uterine spiral artery remodeling. Failures in uterine spiral artery remodeling are linked to diseases of pregnancy. This prompted an investigation of the involvement of NK cells in placentation. NK cell depletion decreased the delivery of proangiogenic ...
Defective placentation and subsequent placental insufficiency lead to maternal and fetal adverse pregnancy outcome, but their pathologic mechanisms are unclear, and treatment remains elusive. The mildly hypertensive BPH/5 mouse recapitulates many features of human adverse pregnancy outcome, with pregnancies characterized by fetal loss, growth restriction, abnormal placental development, and def...
Objective is to evaluate the effectiveness of developed method preventing pregnancy complications with low placentation from early gestation.Material and methods. We have examined 119 pregnant women placentation. This diagnosis was made at 6-7 weeks gestation on basis echographic research. The main group consisted 64 chorionic location who underwent prevention in by complex medicines us a contr...
Workshops are an important part of the IFPA annual meeting. At the IFPA meeting 2008 diverse topics were discussed in 12 themed workshops. Topics covered included: immunology of placentation; galectins and trophoblast invasion; signaling in implantation and invasion; markers to identify trophoblast subpopulations; placental pathology; placental toxicology; stereology; placental transport of fat...
Left Truncation Bias as a Potential Explanation for the Protective Effect of Smoking on Preeclampsia
BACKGROUND We carried out a study to examine whether left truncation bias could explain the negative association between smoking and preeclampsia. METHODS Monte Carlo and other simulation models were used to determine the effect of differential rates of early pregnancy loss among smokers on the relation between smoking and preeclampsia at ≥20 weeks' gestation. Assumptions included no associat...
Objective of the Review: To study impact endometriosis on course and outcomes pregnancy; to propose methods for prevention obstetrics complications in pregnant women with endometriosis. Key Points. Pregnant are at a high risk miscarriage, preterm delivery, preeclampsia, placental disorders, intranatal postnatal bleeding, still birth, rates caesarean section; acute from endometriosis, e.g., spon...
