BACKGROUND Down syndrome (DS) is caused by trisomy 21 (+21), but the aberrations in gene expression resulting from this chromosomal aneuploidy are not yet completely understood. METHODS We used oligonucleotide microarrays to survey mRNA expression in early- and late-passage control and +21 fibroblasts and mid-gestation fetal hearts. We supplemented this… (More)
BACKGROUND CYP19 and PPARgamma are two genes expressed in the placental trophoblast that are important to placental function and are disrupted by phthalate exposure in other cell types. Measurement of the mRNA of these two genes in human placental tissue by quantitative real-time polymerase chain reaction (qPCR) offers a source of potential biomarkers for… (More)
Fetomaternal hemorrhage (FMH) can be associated with significant perinatal mortality. Our review of the literature did not identify any cases of FMH following placement of an intrauterine pressure catheter (IUPC). In our case, an IUPC was inserted in a patient undergoing induction of labor at term. Fetal bradycardia ensued shortly after placement,… (More)
Array comparative hybridization has been used successfully to identify genomic alterations in stillbirth material; however, high DNA quantity and quality requirements may limit its utility in some fetal samples. Molecular inversion probe (MIP) array analysis of FFPE stillbirth autopsy samples circumvents the challenges associated with karyotype and… (More)
Individuals from the following institutions collaborated with the Center's faculty and staff in the research reports included in this year's publication (for individual attributions see specific reports): Introduction This introduction is primarily designed to provide a brief overview of the life and times of the Center in the past year, especially to give… (More)
