The flow and transport of solute molecules in the intricate structure placenta make organ a fetal life-support system.

It was demonstrated that second- and third-trimester therapeutic termination of pregnancy (TOP) is feasible in cases with placenta previa. We report a 34-year-old woman with complex fetal malformations associated with placenta previa. An ultrasound examination at 21 weeks of gestation revealed fetal growth restriction (FGR) and complex fetal malformations associated with a placenta previa. Afte...

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 ...

Adverse influences during fetal life alter the structure and function of distinct cells, organ systems or homoeostatic pathways, thereby 'programming' the individual for an increased risk of developing cardiovascular disease and diabetes in adult life. Fetal programming can be caused by a number of different perturbations in the maternal compartment, such as altered maternal nutrition and reduc...

Throughout in utero development, the placenta plays a key role in controlling growth and development. The placenta acts not only as a gatekeeper of nutrient and waste exchange between mother and developing fetus, but also as a regulator of the intrauterine environment. Its functions can be influenced by the environment encountered throughout pregnancy, thereby altering the appropriate genetic p...

The environment in which the fetus develops is critical for its survival and long-term health. The regulation of normal human fetal growth involves many multidirectional interactions between the mother, placenta, and fetus. The mother supplies nutrients and oxygen to the fetus via the placenta. The fetus influences the provision of maternal nutrients via the placental production of hormones tha...

The foundation for adult health is laid in utero and requires a healthy placenta. A common manifestation of abnormal placental development is impaired fetal growth. While placental pathology is the final common denominator in many cases of fetal growth restriction, a variety of discreet lesions have been described involving both the maternal and fetal circulations at their confluence in the pla...

Vasa previa (VP) is defined as fetal vessels unsupported by either placenta or umbilical cord coursing within the membranes in close proximity to the internal cervical os [1]. The membranous fetal vessels can either lead from the placenta to a velamentous cord insertion (type 1) or connect the main bulk of the placenta to a succenturiate lobe (type 2) [2]. The localization of the membranous fet...

Broken cell preparations of rat and human placentas contain an inner (tyrosyl)-ring iodothyronine deiodinase enzyme with greatest activity when the substrate is 3,5,3'-triiodothyronine (T3). This report describes the deiodination of T3 in the intact placenta and the effect of sodium iopanoate (IA) and propylthiouracil (PTU) on T3 deiodination. Under nembutal anesthesia, the placenta of 60-65-d-...
