BACKGROUND Previous studies have shown that morphine consumption during pregnancy may delay embryo development or cause abnormal nervous system function. OBJECTIVE The present study focused on the effect of maternal morphine consumption on development of placenta and blood corticosteron concentration in addictive pregnant mothers. MATERIALS AND METHODS 24 female rats, 170-200g weight, were ...

Automobile crashes are the largest cause of death for pregnant females and the leading cause of traumatic fetal injury mortality in the United States. Computational models, a useful tool to evaluate the risk of fetal loss in motor vehicle crashes, are limited to quasi-static material properties of the placenta. This study presents a total of 8 dynamic uniaxial tension tests on the full thicknes...

because of an unknown factor, the frequency of complicated pregnancy with placenta previa has been raised during past decade. this study was designed to deepen our understanding of risk factors and outcomes of placenta previa in our country. this study investigated 694 cases of placenta previa comparing with 600 healthy pregnant women with not overlie placenta in two referral and tertiary obste...

Background: Though it is well established that maternal blood-borne signals influence highly the growth of the placenta, the mechanisms are not known. In vitro trophoblast culture models are limited by an inability to reconstruct the polarised bilayer of the human hemochorial placenta. We have used a first trimester villous tissue explant system to investigate how growth factors interact with p...

background: due to increase in pregnancy complications in advanced age, this study was conducted to assess the relationship between advanced maternal age and the pregnancy complications. methods: pregnant women who admitted to the motazedi hospital in kermanshah were included in this analytic–cross sectional study. the study group was 1178 cases that divided into two sub-groups; 35-40 year-old ...

Thyroid hormones (THs) must pass from mother to fetus for normal fetal development and require the expression of placental TH transporters. We investigate the compensatory effect of placental organic anion transporting polypeptide 1c1 (Oatp1c1) and monocarboxylate transporter 8 (Mct8) on maternal thyroid dysfunction. We describe the expressions of these two transporters in placental barriers an...

s: Background: In fluorosis endemic area, the amount of fluoride transferred to the fetus is significant in determining the early onset of fluorosis. The role played by placenta in transporting fluoride and other ions which are present in high concentrations in the local drinking water is studied. Aims & Objectives: The aim of the present study is to decipher the role of placenta in transport o...

Infection with Listeria monocytogenes is a significant health problem during pregnancy. This study evaluates the role of trafficking between maternal organs and placenta in a pregnant guinea pig model of listeriosis. After intravenous inoculation of guinea pigs, the initial ratio of bacteria in maternal organs to placenta was 10(3)-10(4):1. Rapid increase of bacteria in the placenta changed the...
