Metformin passes the placenta. Fetal serum levels are comparable with maternal values.
Identifying the genetic input for fetal growth will help to understand common, serious complications of pregnancy such as fetal growth restriction. Genomic imprinting is an epigenetic process that silences one parental allele, resulting in monoallelic expression. Imprinted genes are important in mammalian fetal growth and development. Evidence has emerged showing that genes that are paternally ...
To investigate the expressions of Fas and Fas ligand (FasL) in human placenta, we studied the expressions of Fas and FasL in placenta with RT-PCR, immunoblotting and immunostaining. We observed amplified products of Fas and FasL transcripts, the band of Fas (52 kDa) and multiple bands of FasL (42-52 kDa) in placenta. Fas and FasL localized mainly on fetal vessels and on syncytiotrophoblasts res...
A technique is described for studying the respiratory function of the placenta using carbon monoxide, a gas whose exchange across the placenta between the maternal and fetal circulations is limited by diffusion rather than blood flow. During the steady state before the introduction of CO, the normal concentration of carboxyhemoglobin in the ewe, [COHb](M), is approximately 0.90%, and that in th...
The placental adhesive disorders such as placenta accreta and placenta percreta are the rare causes of serious obstetric hemorrhages. They are associated with high maternal morbidity and mortality. Placenta percreta is usually diagnosed in the third trimester of pregnancy as a massive postpartum hemorrhage when an attempt to remove the placenta reveals lack of a cleavage plane. Here we report a...
Insufficient oxygen leads to the cessation of growth in favor of cellular survival. Our unique model of high-altitude human pregnancy indicates that hypoxia-induced reductions in fetal growth occur at higher levels of oxygen than previously described. Fetal PO(2) is surprisingly high and fetal oxygen consumption unaffected by high altitude, whereas fetal glucose delivery and consumption decreas...
BACKGROUND Long chain polyunsaturated fatty acids (LCPUFAs) are biologically active fatty acids which regulate placental angiogenesis, inflammation, and oxidative stress. Abnormalities in these aspects have been associated with preeclampsia (PE). Further, placenta has a heterogeneous structure with differential vascularization across different regions. We therefore hypothesize that the distribu...
Objectives: To analyze major image features of ultrasonography and magnetic resonance imaging (MRI), as well as the agreement between the two methods for the diagnosis of placenta accreta. Methods: A retrospective analysis was performed on 378 highly suspected cases of placenta accreta in Obstetrics and Gynaecology Hospital of Fudan University, by comparing ultrasound and MRI results with postp...
OBJECTIVE To demonstrate the safety of fetal delivery through placental incision in a placenta previa pregnancy. METHODS We examined the medical records of 80 women with singleton pregnancy diagnosed with placenta previa who underwent cesarean section between May 2010 and May 2015 at the Department of Obstetrics and Gynecology, Chungbuk National University Hospital. Among the women with place...
These studies were performed to characterize the contribution of the uridine diphosphate glucuronosyltransferase (UGT) enzymes to the clearance of 3'-azido-3'-deoxythymidine (AZT) in vivo and to assess the regulation of UGT activity [including the disposition of the cofactor uridine diphosphate glucuronic acid (UDPGA)] in the placenta. Transport of AZT and the cofactor UDPGA across the human pl...
