CONTEXT Three fourths of US men older than 50 years have been screened with prostate-specific antigen (PSA) for prostate cancer. OBJECTIVE To estimate the receiver operating characteristic (ROC) curve for PSA. DESIGN, SETTING, AND PARTICIPANTS Calculation of PSA ROC curves in the placebo group of the Prostate Cancer Prevention Trial, a randomized,(More)
CONTEXT Findings that protein kinase C (PKC) activity may be altered in mania, and that both lithium carbonate and valproate sodium inhibit PKC-associated signaling in brain tissue, encourage development of PKC inhibitors as candidate antimanic agents. OBJECTIVE To perform a controlled test of antimanic efficacy of the centrally active PKC inhibitor(More)
To determine whether gene expression profiling could improve risk classification and outcome prediction in older acute myeloid leukemia (AML) patients, expression profiles were obtained in pretreatment leukemic samples from 170 patients whose median age was 65 years. Unsupervised clustering methods were used to classify patients into 6 cluster groups(More)
BACKGROUND Frost is an important abiotic stress that limits cereal production in the temperate zone. As the most frost tolerant small grain cereal, rye (Secale cereale L.) is an ideal cereal model for investigating the genetic basis of frost tolerance (FT), a complex trait with polygenic inheritance. Using 201 genotypes from five Eastern and Middle European(More)
Phenology ranks among the best ecosystem processes for fingerprinting climate change since temperature explains a high percentage of the interannual or spatial variation in phenological onset dates. However, roles of other environmental variables, such as foliar nutrient concentrations, are far from adequately understood. This observational study examined(More)
OBJECTIVE To perform systematic analysis of current proton magnetic resonance spectroscopy ((1)H MRS) findings in bipolar disorder (BD). METHOD We grouped the (1)H MRS studies documenting data on the metabolites of N-acetylaspartate (NAA), Choline (Cho), myo-inositol (mI), Glutamate (Glu)/Glutamine (Gln) and Creatine (Cr) separately, for each of the(More)
In a review of the current literature, we identified (1)H MRS studies of major depressive disorder (MDD) that examined the metabolites N-acetylaspartate (NAA), choline (Cho), myo-inositol (mI), glutamate/glutamine/gamma-aminobutyric acid-GABA (Glx), and creatine (Cr). Separate meta-analyses comparing adult and pediatric MDD patients with healthy controls(More)
BACKGROUND In the Prostate Cancer Prevention Trial (PCPT), men receiving finasteride had a 24.8% lower risk of prostate cancer than men receiving placebo but a higher risk of high-grade cancer. We examined the impact of finasteride on the sensitivity and area under the receiver operating characteristic curve (AUC) of prostate-specific antigen (PSA) for(More)
BACKGROUND Cryopreservation of PBMC and/or overnight shipping of samples are required for many clinical trials, despite their potentially adverse effects upon immune monitoring assays such as MHC-peptide tetramer staining, cytokine flow cytometry (CFC), and ELISPOT. In this study, we compared the performance of these assays on leukapheresed PBMC shipped(More)
BACKGROUND The purpose of this investigation was to examine the association of obesity and the adipokines leptin, adiponectin, and interleukin-6 (IL-6) with prostate cancer risk and aggressiveness. METHODS One hundred twenty-five incident prostate cancer cases and 125 age-matched controls were sampled from among participants in the original San Antonio(More)
