The problem of pregnancy loss has medico-social, scientific and practical significance. Almost 85% occur in the I trimester gestation (up to 13 weeks), 15% – II III trimesters. One causes bleeding is retrochorial hematoma (RCH) accumulation blood space due partial detachment chorionic plate from adjacent decidua a genetically normal embryo. article provides an analysis publications that highlig...

STUDY QUESTION Is there a relationship between decidualization and apoptosis of decidual stromal cells (DSC)? SUMMARY ANSWER Decidualization triggers the secretion of soluble factors that induce apoptosis in DSC. WHAT IS KNOWN ALREADY The differentiation and apoptosis of DSC during decidualization of the receptive decidua are crucial processes for the controlled invasion of trophoblasts in ...

The normal endometrium changes after implantation of an embryo. Decidua is the term for the endometrium during a pregnancy, which is formed under the influence of progesterone as the maternal part of the placenta. It has a histologically distinct appearance, displaying large polygonal decidual cells in the stroma. These are enlarged endometrial stromal cells, which resemble epithelium. Interact...

In the maternal decidua, natural killer (NK) cells, characterized by lack of CD16, are found in direct contact with the fetal extravillous trophoblasts (EVTs). It is yet unknown which factors contribute to the specific homing of this unique NK subset to the decidua. In this study we analyze the chemokine receptor repertoire on various NK populations derived from the peripheral blood and decidua...

BACKGROUND In normal pregnancy, predominant type 2 cytokines help maintain pregnancy, and a T-helper (Th)1 type response is associated with unexplained recurrent spontaneous abortion (RSA). However, Th2 and T-cytotoxic (Tc)2 cells have not been localized at the implantation site in RSA. METHODS Twenty-one cases with RSA were classified into RSA with normal chromosomal content (RSA-N, n = 10) ...

Diacylglycerol lipase activity has been demonstrated in human fetal membranes and decidua vera tissues. The specific activity of the enzyme is highest in the microsomal fraction of decidua vera tissue. The acylester bond at the sn-1 position of 1,2-diacyl-sn-glycerol is hydrolyzed followed by release of the fatty acid at the sn-2 position. The diacylglycerol lipase activity present in the micro...

The aim of this study was to determine whether expression of prostanoid receptor genes varied with gestational age or labour in the decidua and chorion of baboons. Tissues were obtained at the time of Caesarean hysterectomy in 15 baboons, 10 prior to the onset of labour in the last third of pregnancy and 5 in spontaneous labour at term. Expression of prostanoid receptor genes was determined usi...

We monitored dynamics of stem water deficit (ΔW) and needle water potential (Ψ) during two consecutive growing seasons (2011 and 2012) in a dry inner Alpine environment (750 m above sea level, Tyrol, Austria), where Pinus sylvestris, Picea abies and Larix decidua form mixed stands. ΔW was extracted from stem circumference variations, which were continuously recorded by electronic band dendromet...

The aim of the present study was to explore the levels of matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the maternal umbilical serum, placenta and decidua of patients with preeclampsia compared with those in normotensive pregnant females. A total of 73 pregnant females were recruited as the test subjects, including 43 inpatients with hypertensive dis...
