The Primary Immune Deficiency Treatment Consortium (PIDTC) is a network of 33 centers in North America that study the treatment of rare and severe primary immunodeficiency diseases. Current protocols address the natural history of patients treated for severe combined immunodeficiency (SCID), Wiskott-Aldrich syndrome, and chronic granulomatous disease(More)
5-enolPyruvylshikimate-3-phosphate synthase (EPSP synthase; 3-phosphoshikimate 1-carboxyvinyl-transferase; EC 2.5.1.19) is a chloroplast-localized enzyme of the shikimate pathway in plants. This enzyme is the target for the nonselective herbicide glyphosate (N-phosphonomethylglycine). We have previously isolated a full-length cDNA clone of EPSP synthase(More)
A deletion variant of human interleukin-3, hIL-3(15-125), was produced in the periplasmic space of Escherichia coli and had full activity in an AML193.1.3 cell proliferation assay. Libraries of random single-amino acid substitutions were constructed at each of 105 positions in the gene for hIL-3(15-125). Approximately eight single-site substitutions at each(More)
Children with autism spectrum disorders (ASD) have unique developmental and behavioral phenotypes, and they have specific challenges with communication, social skills, and repetitive behaviors. At this time, no single etiology for ASD has been identified. However, evidence from family studies and linkage analyses suggests that genetic factors play a pivotal(More)
Enhancing Developmentally Oriented Primary Care (EDOPC) is a formal didactic curriculum based on Healthy Steps materials that is designed to improve practicing pediatricians’ knowledge and confidence in developmental screening within the medical home. We modified the EDOPC program to provide a formal curriculum to pediatric residents serving children in(More)
Hydrogen peroxide (H(2)O(2)) is commonly formed in microbial habitats by either chemical oxidation processes or host defense responses. H(2)O(2) can penetrate membranes and damage key intracellular biomolecules, including DNA and iron-dependent enzymes. Bacteria defend themselves against this H(2)O(2) by inducing a regulon that engages multiple defensive(More)
A combinatorial mutagenesis strategy was used to create a collection of nearly 500 variants of human interleukin 3 (IL-3), each with four to nine amino acid substitutions clustered within four linear, nonoverlapping regions of the polypeptide. The variants were secreted into the periplasm of Escherichia coli and supernatants were assayed for IL-3(More)
CONTEXT Utilization of primary care settings offers a promising approach to enhance parenting practices that are critical for promoting early childhood development. Determining the impact of existing primary care interventions on key parenting behaviors will aid providers and policy makers as they seek strategies to improve early child outcomes. OBJECTIVE(More)
Chemical modification of Escherichia coli 5-enolpyruvylshikimate-3-phosphate synthase, a target for the nonselective herbicide glyphosate (N-phosphonomethylglycine), with pyridoxal 5'-phosphate suggested that Lys-22 (equivalent to Lys-23 of the Petunia hybrida enzyme) is a potential active site residue (Huynh, Q. K., Kishore, G. M., and Bild, G. S. (1988)(More)
OBJECTIVE To assess the utility of a telephone-based interview system in providing ongoing monitoring of the developmental and functional status of children with both positive newborn screens for Krabbe disease and low galactocerebrosidase activity on confirmatory testing, and to determine whether this approach provides improved compliance with follow-up(More)
