BACKGROUNDUnderstanding the physiology of pregnancy enables effective management of pregnancy complications that could otherwise be life threatening for both mother and fetus. A functional uterus (i) retains the fetus in utero during pregnancy without initiating stretch-induced contractions and (ii) is able to dilate the cervix and contract the myometrium at ...

Preeclampsia is an important complication in pregnancy, characterized by hypertension and proteinuria in the second half of pregnancy. Generalized activation of the inflammatory response is thought to play a role in the pathogenesis of pre-eclampsia. Monocytes may play a central role in this inflammatory response. Monocytes are short lived cells ...

Abstract Luteinizing hormone (LH) and human chorionic gonadotropin (hCG) are integral components of the hypothalamic-pituitary-gonadal axis, which controls sexual maturation and functionality. In the absence of signaling through their shared receptor, fetal sexual differentiation and post-natal development cannot proceed normally. Although they share a high degree of homology, the physiologic ...

Although erythropoietin plays a significant role in human metabolism, relatively little attention has been devoted in scientific literature to its role and mechanisms regulating its secretion in pregnancy. The authors of this article discussed the following issues: - construction, biological role and regulation of erythropoietin secretion, - its extra-hematologic effect, ...

Preeclampsia is associated with hypertension and increased infant and maternal morbidity and mortality. The underlying cause of preeclampsia is largely unknown, but it is clear that an immunological component plays a key pathophysiological role. This review will highlight immunological key players in the pathology of preeclampsia and discuss their role ...

Nitric oxide (NO) regulates placental blood flow and actively participates in trophoblast invasion and placental development. Asymmetric dimethylarginine (ADMA) can inhibit NO synthase, which generates NO. ADMA has been associated with uterine artery flow disturbances such as preeclampsia. Substantial experimental evidence has reliably supported the hypothesis that an adverse in ...

Pregnancy success is determined by a complex progress that includes trophoblast invasion and placentation. Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) are metal-dependent endopeptidases capable of degrading extracellular matrix, and appear to play a critical role in trophoblast invasion. This article reviews in detail the role of MMPs, ...

Pregnancy-associated glycoproteins (PAGs) are powerful pregnancy markers in domestic cattle. These proteins are expressed in mono- and binucleate trophoblast cells from the first days of gestation until calving. Different molecules were identified as being expressed at various stages of pregnancy. However, up to date, their functions and activities during pregnancy ...

The physiological states pregnancy and parturition are undoubtedly associated with clinical changes of most of the autoimmune diseases. An altered Th1/Th2 balance has been proposed as an underlying mechanism. A pregnancy has protective effect on Th1-mediated autoimmune diseases, and a deteriorative effect on Th2-mediated autoimmune diseases. Numerous studies, both experimental ...
