The goal of this study was to evaluate the effect of olanzapine or risperidone treatment on beta-cell function in healthy volunteers. Subjects were randomly assigned to single-blind therapy with olanzapine (10 mg/d; n = 17), risperidone (4 mg/d; n = 13), or placebo (n = 18) for 15-17 d. Insulin secretion was quantitatively assessed at baseline and the end(More)
The human proton-dependent dipeptide transporter (PEPT1, gene SLC15A1) is important for intestinal absorption of di- and tripeptides and a variety of peptidomimetic compounds. Using a DNA polymorphism discovery panel of 44 ethnically diverse individuals, nine nonsynonymous and four synonymous coding-region single-nucleotide polymorphisms (SNPs) were(More)

The primary objective of this study was to evaluate insulin sensitivity in healthy subjects treated with olanzapine or risperidone. Subjects were randomly assigned to single-blind therapy with olanzapine (10 mg/d), risperidone (4 mg/d), or placebo for approximately 3 wk. Insulin sensitivity was assessed pre- and posttreatment using a 2-step,(More)
AIMS In this retrospective analysis, we assessed the short-term risk of treatment-emergent diabetes (TED) among patients with schizophrenia during clinical trials of antipsychotic medications. METHOD From a non-diabetic cohort of patients with schizophrenia (n=5013), the relationship between baseline non-fasting glucose measurement, presence at baseline(More)
Using the simulated data set from Genetic Analysis Workshop 13, we explored the advantages of using longitudinal data in genetic analyses. The weighted average of the longitudinal data for each of seven quantitative phenotypes were computed and analyzed. Genome screen results were then compared for these longitudinal phenotypes and the results obtained(More)
Forty-eight children with untreated acute lymphocytic leukemia were evaluated with regard to their clinical presentation and the surface membrane characteristics, mitogen responsiveness, and cytochemical staining features of their lymphoblasts. The presence at diagnosis of 20% or more bone marrow lymphoblasts possessing T-cell surface markers was associated(More)
Fluctuations in the percentages and absolute numbers of T and B lymphocytes were observed in the peripheral blood of a patient with severe combined immunodeficiency maintained in a gnotobiotic environment. Up to 24 months of age, 72-86% of the lymphocytes had surface membrane immunoglobulin (SMIg), 37-47% bore a receptor for C3(EAC-RFC), and 3-12.5% formed(More)
