Drug-related stimuli, through conditioning, are thought to acquire incentive motivational properties that code possible reward availability and elicit an attentional bias, possibly through increased "bottom-up" neural processing. The processes underlying this attentional bias are considered important in the maintenance of addiction, and crucially, in(More)
The present work uses alpha-conotoxin ImI (CTx ImI) to probe the neurotransmitter binding site of neuronal alpha7 acetylcholine receptors. We identify key residues in alpha7 that contribute to CTx ImI affinity, and use mutant cycles analysis to identify pairs of residues that stabilize the receptor-conotoxin complex. We first mutated key residues in the(More)
In this paper we investigate the role blogs played within the context of the Egyptian revolution of early 2011 using blog data authored between 2004-2011. We conducted topic modeling analysis to gain a longitudinal view of the interaction of societal, personal and revolutionary blog topics over this period. Furthermore, a qualitative analysis of blog posts(More)
Much data available from on-line databases is self-reported. Because of this the quality and consistency of web available data is often suspect. This paper presents Supply Chain Diversifier, a service directory that collects and presents data from the Small Business Administration website and a number of web based subscription registries of minority(More)
Both metabolic syndrome (MetS) and elevated LDL cholesterol (LDL-C) increase the risk for cardiovascular disease (CVD). We hypothesized that low HDL cholesterol (HDL-C) would further increase CVD risk in women having both conditions. To assess this, we recruited 89 women with MetS (25-72 y) and LDL-C ≥ 2.6 mmol/L. To determine whether plasma HDL-C(More)
BACKGROUND Administrative and survey data are two key data sources for population-based research about chronic disease. The objectives of this methodological paper are to: (1) estimate agreement between the two data sources for irritable bowel syndrome (IBS) and compare the results to those for inflammatory bowel disease (IBD); (2) compare the frequency of(More)
Integration and analysis of clinical data collected in multiple data sources over a long period of time is a major challenge even when data warehouses and metadata registries are used. Since most metadata registries focus on describing data elements to establish domain consistent data definition and providing item libraries, hierarchical and temporal(More)
