Soluble and cell-wall-bound phenolics in mycorrhizas of Larix decidua-Laccaria amethystea and in nonmycorrhizal fine roots of larch grown in sterile culture were analyzed by HPLC. The soluble phenolics p-hydroxybenzoylglucose, p-hydroxybenzoic acid glucoside, picein, catechin, and epicatechin were identified in nonmycorrhizal fine roots. The same phenolics also occurred in mycorrhizas, but only...

Several studies have shown that decidual tissue produces soluble factors which can mediate a variety of immunosuppressive activities. In order to assess whether prostaglandin E2 (PGE2) was present in supernatants produced by explant culture of 10 human specimens of first trimester decidua. The effect of the supernatants from the two different series (with and without indomethacin treatment) of ...

The human decidua is a specialized tissue characterized by embryo-receptive properties. It is formed during the secretory phase of menstrual cycle from uterine mucosa termed endometrium. The decidua is composed of glands, immune cells, blood and lymph vessels, and decidual stromal cells (DSCs). In the process of decidualization, which is controlled by oestrogen and progesterone, DSCs acquire sp...

Progesterone is central to many reproductive processes and is critical in regulating the menstrual cycle and maintaining pregnancy. We discuss here similarities in the molecular mechanisms that regulate the process of decidualisation in endometrial stromal cells and uterine quiescence in myometrial smooth muscle cells. We discuss recent evidence that the decidua may be an important mediator of ...

We studied the incidence of pathogenic bacteria and concurrent infections with human cytomegalovirus (CMV) and herpes simplex virus (HSV) type 1 and 2 in biopsy samples from the placenta and decidua of women with healthy pregnancies. By polymerase chain reaction analysis, we found that 38% of placental samples were positive for selected bacteria and viruses. CMV, HSV-1, and HSV-2 were detected ...

Disturbances in decidual and placental vascular development may play a role in the pathogenesis of pregnancy complications. This study focused on the role of angiogenic factors in the first trimester in the pathogenesis of preeclampsia (PE) and/or fetal growth restriction (FGR). First-trimester decidua was obtained during chorionic villous sampling.The expression of the angiogenic factors was d...
