Preventive Medicine and Environmental Health Faculty Publications

Public health systems and services research (PHSSR) is defined as "a field of study that examines the organization, financing, and delivery of public health services within communities and the impact of those services." PHSSR is a relatively young field and suffers from a paucity of research resources. In this article, we describe the development and utility of a data resource, housed on the Health Services and Sciences Research Resources website maintained by the National Library of Medicine, which provides easy access to instruments, indices, and datasets that are relevant to PHSSR researchers. We also investigate efforts to promote the use …

The North American Transportation Security Center – Technology Prototype Gap Analysis, Steven Douglas Kreis, Michael M. Barclay

Kentucky Transportation Center Research Report

Executive Summary

There are over 800,000 hazardous materials (hazmat) shipments over the nation’s roads each day. According to the U.S. Department of Homeland Security (DHS), terrorist activity related to the transportation of hazardous materials represents a significant threat to public safety and the nation’s critical infrastructure. Specifically, the federal government has identified the government’s inability to track hazmat shipments on a real-time basis as a significant security vulnerability.

In 2004, the U.S. Federal Motor Carrier Safety Administration (FMCSA) completed a study to determine if “smart truck” technology such as GPS tracking, wireless modems, panic buttons, and onboard computers could be …

Two-dimensional (2D) videoconferencing has been explored widely in the past 15–20 years to support collaboration in healthcare. Two issues that arise in most evaluations of 2D videoconferencing in telemedicine are the difficulty obtaining optimal camera views and poor depth perception. To address these problems, we are exploring the use of a small array of cameras to reconstruct dynamic three-dimensional (3D) views of a remote environment and of events taking place within. The 3D views could be sent across wired or wireless networks to remote healthcare professionals equipped with fixed displays or with mobile devices such as personal digital assistants (PDAs). …

The Significance Of The Shift Toward As-Applied Challenges In Election Law, Joshua A. Douglas

Law Faculty Scholarly Articles

Election law is experiencing immense change. The Supreme Court’s recent approach to election law cases has significant implications for the scope of the right to vote and the meaning of political participation and self-governance. This Article examines the importance of the Court’s recent pronouncement that plaintiffs can bring election law challenges only as applied to a particular political actor for a particular situation, instead of challenging a law in its entirety. The “as-applied only” rule may seem like simply a procedural method for construing election laws or a mere semantic distinction, but, as I show, in reality the Court’s decisions …

Drug Abuse Treatment Beyond Prison Walls, Carl Leukefeld, Carrie B. Oser, Jennifer Havens, Michele Staton Tindall, Jennifer Mooney, Jamieson B. Duvall, Hannah Knudsen

Behavioral Science Faculty Publications

The period surrounding release from prison is a critical time for parolees, bearing the potential for a drug-free and crime-free life in the community but also high risks for recidivism and relapse to drugs. The authors describe two projects. The first illustrates the use of a formal Delphi process to elicit and combine the expertise of treatment providers, researchers, corrections personnel, and other stakeholders in a set of statewide guidelines for facilitating re-entry. The second project is a six-session intervention to enable women to protect themselves against acquiring or transmitting HIV in their intimate relationships.

Borrelia Burgdorferi Ebfc Defines A Newly-Identified, Widespread Family Of Bacterial Dna-Binding Proteins, Sean P. Riley, Tomasz Bykowski, Anne E. Cooley, Logan H. Burns, Kelly Babb, Catherine A. Brissette, Amy Bowman, Matthew L. Rotondi, M. Clarke Miller, Edward Demoll, Kap Lim, Michael G. Fried, Brian Stevenson

Microbiology, Immunology, and Molecular Genetics Faculty Publications

The Lyme disease spirochete, Borrelia burgdorferi, encodes a novel type of DNA-binding protein named EbfC. Orthologs of EbfC are encoded by a wide range of bacterial species, so characterization of the borrelial protein has implications that span the eubacterial kingdom. The present work defines the DNA sequence required for high-affinity binding by EbfC to be the 4 bp broken palindrome GTnAC, where ‘n’ can be any nucleotide. Two high-affinity EbfC-binding sites are located immediately 5′ of B. burgdorferi erp transcriptional promoters, and binding of EbfC was found to alter the conformation of erp promoter DNA. Consensus EbfC-binding …

Polyglutamine Disruption Of The Huntingtin Exon 1 N Terminus Triggers A Complex Aggregation Mechanism, Ashwani K. Thakur, Murali Jayaraman, Rakesh Mishra, Monika Thakur, Veronique M.

Simple polyglutamine (polyQ) peptides aggregate in vitro via a nucleated growth pathway directly yielding amyloid-like aggregates. We show here that the 17-amino-acid flanking sequence (HTT^NT) N-terminal to the polyQ in the toxic huntingtin exon 1 fragment imparts onto this peptide a complex alternative aggregation mechanism. In isolation, the HTT^NT peptide is a compact coil that resists aggregation. When polyQ is fused to this sequence, it induces in HTT^NT, in a repeat-length dependent fashion, a more extended conformation that greatly enhances its aggregation into globular oligomers with HTT^NT cores and exposed polyQ. In a second …

Evaluation Of The Use Of Snowplowable Raised Pavement Markers, Kenneth R. Agent, Eric R. Green

Kentucky Transportation Center Research Report

The objective of this study was to evaluate the effectiveness and durability of snowplowable raised pavement markers (RPM) installed on the RPM system in Kentucky. The durability evaluation dealt with the marker housing.

The data show that continued use of the currently approved snowplowable RPM can be justified if the castings are properly installed on new pavements with a commitment that the pavement will be maintained. An evaluation of centerline rumble strips installations showed that they should be considered on rural, two-lane roads with 12-foot lane widths (having new pavements) and paved shoulders.

Detection Of Cwd Prions In Urine And Saliva Of Deer By Transgenic Mouse Bioassay, Nicholas J. Haley, Davis M. Seelig, Mark D. Zabel, Glenn C. Telling, Edward A. Hoover

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Chronic wasting disease (CWD) is a prion disease affecting captive and free-ranging cervids (e.g. deer, elk, and moose). The mechanisms of CWD transmission are poorly understood, though bodily fluids are thought to play an important role. Here we report the presence of infectious prions in the urine and saliva of deer with chronic wasting disease (CWD). Prion infectivity was detected by bioassay of concentrated, dialyzed urine and saliva in transgenic mice expressing the cervid PrP gene (Tg[CerPrP] mice). In addition, PrP(CWD) was detected in pooled and concentrated urine by protein misfolding cyclic amplification (PMCA). The concentration of abnormal prion protein …

A Discontinuous Rna Platform Mediates Rna Virus Replication: Building An Integrated Model For Rna-Based Regulation Of Viral Processes, Baodong Wu, Judit Pogany, Hong Na, Beth L. Nicholson, Peter D. Nagy, K. Andrew White

Plant Pathology Faculty Publications

Plus-strand RNA viruses contain RNA elements within their genomes that mediate a variety of fundamental viral processes. The traditional view of these elements is that of local RNA structures. This perspective, however, is changing due to increasing discoveries of functional viral RNA elements that are formed by long-range RNA-RNA interactions, often spanning thousands of nucleotides. The plus-strand RNA genomes of tombusviruses exemplify this concept by possessing different long-range RNA-RNA interactions that regulate both viral translation and transcription. Here we report that a third fundamental tombusvirus process, viral genome replication, requires a long-range RNA-based interaction spanning approximately 3000 nts. In vivo …

Biosystems and Agricultural Engineering Faculty Publications

Biologically catalyzed reactions often produce enantiomers of the product; however, only one configuration is desired. Reaction conditions are known to affect enantiomer ratios and reaction kinetics, but little is known regarding the effect of processing conditions on whole-cell biocatalysis. Saccharomyces cerevisiae cells were grown in batch on glucose at pH = 4, 5, and 7, and then immobilized on Celite beads or in calcium alginate beads and used as the biocatalyst for the conversion of acetophenone in hexane to (S)-1-phenylethanol at water activities of 0.37, 0.61, and 0.80. S. cerevisiae was used as a model microorganism for the whole-cell catalyzed …
