Diffuse large B-cell lymphoma (DLBCL), the most common subtype of non-Hodgkin's lymphoma, is clinically heterogeneous: 40% of patients respond well to current therapy and have prolonged survival, whereas the remainder succumb to the disease. We proposed that this variability in natural history reflects unrecognized molecular heterogeneity in the tumours.(More)
The temporal program of gene expression during a model physiological response of human cells, the response of fibroblasts to serum, was explored with a complementary DNA microarray representing about 8600 different human genes. Genes could be clustered into groups on the basis of their temporal patterns of expression in this program. Many features of the(More)
In April 2008, the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the American College of Obstetricians and Gynecologists, and the Society for Maternal-Fetal Medicine partnered to sponsor a 2-day workshop to revisit nomenclature, interpretation, and research recommendations for intrapartum electronic fetal heart rate(More)
The human alpha7 neuronal nicotinic acetylcholine receptor gene (HGMW-approved symbol CHRNA7) has been characterized from genomic clones. The gene is similar in structure to the chick alpha7 gene with 10 exons and conserved splice junction positions. The size of the human gene is estimated to be larger than 75 kb. A putative promoter 5' of the translation(More)
Acardiac twinning affects 1 in 100 monozygotic twin pregnancies and 1 in 35,000 pregnancies overall. The presence of an acadiac twin requires the normal (or "pump") twin to provide circulation for itself, as well as the acardiac sibling. In many cases the acardiac twin is almost equal to the normal twin. The principal perinatal problems associated with(More)
OBJECTIVES To investigate negative pressure wound therapy (NPWT) to prevent wound dehiscence and infection after high-risk lower extremity trauma. DESIGN Prospective randomized multicenter clinical trial. SETTING Four Level I trauma centers. PATIENTS/PARTICIPANTS Blunt trauma patients with one of three high-risk fracture types (tibial plateau, pilon,(More)
Fetal death is a tragedy for mother, family, and obstetrician. Recent reviews of fetal death indicate that nearly half occur in pregnancies that are not candidates for traditional antepartum testing. We conducted a prospective evaluation of the effectiveness of a fetal movement screening program in reducing the fetal mortality rate. During a 7-month control(More)
The four-quadrant sum of amniotic fluid pockets (amniotic fluid index) was studied prospectively in 791 normal pregnancies. Interobserver and intraobserver variation was 3.1% and 6.7%, respectively. Logarithmic transformations were used to establish the mean and 90% confidence intervals for the amniotic fluid index at each week of gestation. In term(More)
Effords to identify cDNA clones encoding chloroplastic envelope membrane proteins of Pisum sativum L. led to the isolation of a clone encoding a 92 kDa protein found in both the inner envelope membrane and the soluble fraction of chloroplasts. Sequential transcription and translation from the insert of this clone yielded a 102 kDa protein that could be(More)
If trade barriers are managed by ine cient institutions, trade liberalization can lead to greater-than-expected gains. We examine Chinese textile and clothing exports before and after the elimination of externally imposed export quotas. Both the surge in export volume and the decline in export prices following quota removal are driven by net entry. This(More)
