Preeclampsia is associated with oxidative stress, which is suspected to play a role in hypertension, placental ischemia, and fetal demise associated with the disease. Various cellular sources of oxidative stress, such as neutrophils, monocytes, and CD4(+) T cells have been suggested as culprits in the pathophysiology of preeclampsia. The objective of this study was to examine a role of circulat...

introduction: this study was performed to establish a complementary method to the diagnosis of complete hydatidiform mole and its differentiation from the other cases of gestational trophoblastic disease by measuring the total (alp) and placental alkaline phosphatase (plap) specific activity. materials and methods: serum and tissue extracts from 13 patients, 13 normal non-pregnant and 30 pregna...

Cyclic adenosine 3’,S’-monophosphate (cAMP) has been implicated in the control of placental function. The present investigation was designed to evaluate the actions of cAMP analogues on the control of rat placental development. Two model systems were used to assess the actions of cAMP in the placenta: 1) a rat placental cell line and 2) rat labyrinth placental explants. Elevation of intracellul...

This paper reviews bovine placental development, anatomy (microscopic and gross), nomenclature and classification. The paper focuses on the biology of those specialized cells that arise from the outermost layer of very early embryos, the trophoblast cells, and on placental macrophages, cells that play a key role in fetal/placental defense. Data is presented from an immunohistochemical quantitat...

The presence of immune cells in the placental bed is important for both mother and child. Although various immune cells can be found in the placental bed, such as regulatory T cells and dendritic cells, uterine NK cells and macrophages are the most prominent immune cells in the placental bed in early pregnancy. uNK cell and macrophage numbers in the placental bed decrease in the third trimester...

Background: Adrenomedullin (ADM) is a vasoactive peptide hormone found in adrenal medulla, central nervous system, immune cells, and muscle, expressed the uterus placenta. ADM plays important roles angiogenesis, vasodilation, inflammation. Altered levels of have been implicated adverse pregnancy outcomes like fetal growth restriction pre-eclampsia. Animal models can be useful tools for examinin...

BACKGROUND Placental Plasmodium falciparum malaria can trigger intervillositis, a local inflammatory response more strongly associated with low birthweight than placental malaria infection alone. Fetal growth (and therefore birthweight) is dependent on placental amino acid transport, which is impaired in placental malaria-associated intervillositis. Here, we tested the hypothesis that mechanist...

In this study, the effectiveness of vasoprotective Diosmin for prevention pre-eclampsia in pregnant women high-risk group with severe forms placental insufficiency was evaluated. The choice prophylactic agent clinical is justified by close pathogenetic relationship between and on one hand, proved fetoprotective action case other hand. It shown that a normalizing effect uterine-placental- fetal ...

Intrauterine growth restriction (IUGR) and pregnancy hypertensive disorders such as preeclampsia (PE) associated with IUGR share a common placental phenotype called "placental insufficiency", originating in early gestation when high availability of energy is required. Here, we assess mitochondrial content and the expression and activity of respiratory chain complexes (RCC) in placental cells of...

During placental malaria, Plasmodium falciparum infected erythrocytes sequester in the placenta, causing health problems for both the mother and fetus. The specific adherence is mediated by the VAR2CSA protein, which binds to placental chondroitin sulfate (CS) on chondroitin sulfate proteoglycans (CSPGs) in the placental syncytium. However, the identity of the CSPG core protein and the cellular...
