I t is recognized that women with gesta-tional diabetes mellitus (GDM) who have significantly elevated fasting blood glucose levels are at increased risk for fetal macrosomia and perinatal morbidity if treatment is not provided (1,2). The association of milder forms of GDM with perinatal morbidity and mortality remains unclear, primarily because the(More)
In order to characterize the variability of the expressed human T-cell receptor (TCR) beta-chain repertoire and contrast this variability to the known murine beta-chain repertoire, 15 independent complementary DNA (cDNA) clones containing TCR beta-chain variable region (V beta) genes were isolated from a human tonsil cDNA library. The nucleotide and derived(More)
To characterize the T cell receptor repertoire in an immune response in which the Ia and nominal antigenic determinants are defined and limited, we have cloned and sequenced the expressed receptors from four independent, beef insulin-specific T cell lines from C57BL mice. Each of these lines responded to beef but not to the pork insulin, thus defining the(More)
We have isolated and characterized the gene coding for the mouse Fc receptor that is termed Fc gamma RIIa. The gene contains five exons and spans approximately 9 kilobases. Unlike most members of the immunoglobulin gene superfamily, this gene utilizes multiple exons to encode its leader peptide. The first exon encodes the hydrophobic region of the signal(More)
OBJECTIVE The purpose of this study was to determine whether supine hypotensive syndrome is caused by a decreased baroreflex gain that results in inadequate compensatory responses to restore cardiac output. STUDY DESIGN Ten third-trimester gravid women with symptoms that were suggestive of supine hypotensive syndrome and 10 control subjects without(More)
Terminal deoxynucleotidyl transferase (TdT) is a nuclear enzyme found in early lymphocytes which is thought to increase junctional diversity of TCR and Ig genes by the addition of N regions. TdT is normally found only in immature lymphoid cells and is turned off in both mature B and T cells. To investigate the regulation of TdT gene expression, pre-B and(More)
