Raccoon () biomarker and rabies antibody response to varying oral rabies vaccine bait densities in northwestern Pennsylvania.

Distribution of oral rabies vaccine baits has been used as a strategy for managing rabies in the United States since the 1990s. Since that time, efforts have been made to improve baiting strategies with a focus on bait density to maximize both efficiency and cost effectiveness. An optimal rabies management strategy includes a vaccine bait preferred by the target species that is distributed at the minimal density needed to achieve population immunity to prevent rabies spread.

Predicting Electrophoretic Mobility of Protein-Ligand Complexes for Ligands from DNA-Encoded Libraries of Small Molecules.

Selection of target-binding ligands from DNA-encoded libraries of small molecules (DELSMs) is a rapidly developing approach in drug-lead discovery. Methods of kinetic capillary electrophoresis (KCE) may facilitate highly efficient homogeneous selection of ligands from DELSMs. However, KCE methods require accurate prediction of electrophoretic mobilities of protein-ligand complexes.

Prediction of protein-DNA complex mobility in gel-free capillary electrophoresis.

Selection of protein binders from highly diverse combinatorial libraries of DNA-encoded small molecules is a highly promising approach for discovery of small-molecule drug leads. Methods of kinetic capillary electrophoresis provide the high efficiency of partitioning required for such selection but require the knowledge of electrophoretic mobility of the protein-ligand complex. Here we present a theoretical approach for an accurate estimate of the electrophoretic mobility of such complexes.

Influence of oral rabies vaccine bait density on rabies seroprevalence in wild raccoons.

The effect of different oral rabies vaccine (ORV) bait densities (75, 150, and 300 baits/km(2)) on the seroprevalence of rabies virus neutralizing antibodies (RVNAs) in raccoons (Procyon lotor) was assessed at a 15% seroprevalence difference threshold in rural areas of northeast Ohio. Results (n=588 raccoons) indicated that seropositivity for RVNAs was associated with both bait density and bait campaign frequency. Associations were not detected for raccoon gender, age, or macro-habitat.

Skunk rabies in California (1992-2003)--implications for oral rabies vaccination.

Skunk-variant rabies is endemic in California (United States), and the development of oral vaccines and baits to vaccinate skunks is in progress. In 2003, the California Department of Public Health (CDPH) began to quantify the impacts of skunk-variant rabies and to assess the feasibility of using oral rabies vaccination (ORV) as a containment measure. The CDPH rabies case data for skunks were spatially depicted and analyzed using a geographic information system.

Tridimensional personality traits of college student marijuana users.

The present study examined the possibility that marijuana use among college students might be associated with particular personality traits. College student volunteers (N = 176) were administered the Tridimensional Personality Questionnaire and a drug-use questionnaire. Analysis of variance showed that the mean score on Novelty Seeking was significantly higher and on Persistence significantly lower among lifetime marijuana users than among nonmarijuana using peers.

Sex differences in the acquisition of a radial maze task in the CD-1 mouse.

The purpose of the present study was to investigate spatial processing performance in male and female CD-1 mice. A substantial literature supports the existence of significant sex differences in both human and rodent models of learning and memory. The nature of these differences is dependent upon the parameters of the task, species and strain of animal.
