Recently, a novel method for detection of DNA synthesis has been developed based on the incorporation of 5-ethynyl-2'-deoxyuridine (EdU), a thymidine analogue, into cellular DNA and the subsequent reaction of EdU with a fluorescent azide in a copper-catalyzed [3+2] cycloaddition ("Click" reaction). In the present study, we evaluated this method for studying(More)
4-(Dimethylamino)-N-(4-(4-(2-methoxyphenyl)piperazin-1-yl)butyl)benzamide (WC-10), a N-phenyl piperazine analog, has been shown to have high affinity and selectivity for dopamine D(3) receptors versus dopamine D(2) receptors (Chu et al. [2005] Bioorg Med Chem 13:77-87). In this study, WC-10 was radiolabeled with tritium (specific activity = 80 Ci/mmol) and(More)
Combined psychosocial and nutrition interventions improve the development of infants. However, there is a paucity of studies examining the effectiveness of such interventions in humanitarian settings. This article examines the impact of combining a group-based psychosocial intervention with an existing emergency feeding program for internally displaced(More)
4-(Dimethylamino)-N-(4-(4-(2-methoxyphenyl)piperazin-1-yl)butyl)benzamide (WC-10), a N-phenyl piperazine analog, displays high affinity and moderate selectivity for dopamine D(3) receptors versus dopamine D(2) receptors (Chu et al. [2005] Bioorg Med Chem 13:77-87). In this study, WC-10 was radiolabeled with tritium (specific activity = 80 Ci/mmol), and(More)
A series of microPET imaging studies were conducted in anesthetized rhesus monkeys using the dopamine D2-selective partial agonist, [(11)C]SV-III-130. There was a high uptake in regions of brain known to express a high density of D2 receptors under baseline conditions. Rapid displacement in the caudate and putamen, but not in the cerebellum, was observed(More)
BACKGROUND Resistance to modern adjuvant treatment is in part due to the failure of programmed cell death. Therefore the molecules that execute the apoptotic program are potential targets for the development of anti-cancer therapeutics. The sigma-2 receptor has been found to be over-expressed in some types of malignant tumors, and, recently, small molecule(More)
OBJECTIVES Emotional processing has rarely been investigated in those "at risk" of developing an eating disorder. This study investigated the processing of six basic emotions depicted on faces in an "at risk" group, compared to a control group. DESIGN Participants were women with high (N=29) and low (N=23) levels of eating disorder symptoms who were not(More)
Papaverine, 1-(3,4-dimethoxybenzyl)-6,7-dimethoxyisoquinoline, a specific inhibitor of phosphodiesterase (PDE) 10A with IC(50) values of 36 nM for PDE10A, 1,300 nM for PDE3A and 320 nM for PDE4D, has served as a useful pharmaceutical tool to study the physiological role of PDE10A. Here, we report the radiosynthesis of [(11)C]papaverine and the in vitro and(More)
A series of microPET imaging studies were conducted in anesthetized rhesus monkeys using the dopamine D₃-selective partial agonist, [¹⁸F]5. There was variable uptake in regions of brain known to express a high density of D₃ receptors under baseline conditions. Pretreatment with lorazepam (1 mg/kg, i.v. 30 min) to reduce endogenous dopamine activity before(More)
