Reframing Communication About Zika And Mosquitoes To Increase Disease Prevention Behavior, Amanda E. Sorensen, Rebecca C. Jordan, Shannon Ladeau

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Emergence of invasive vector species and the diseases they carry present a clear danger to the public as well as a challenge for scientists and experts to control effectively. Given the urgent need to address this phenomenon, we suggest that desired public action toward these invasive vectors can be motivated through intentional framing in science communication. In this paper, we sought to evaluate the effect of framing about ZIKV (Zika virus) on reported willingness to comply with mosquito prevention action. Post framing intervention, we found a significant increase (N = 26, p < 0.001) in individuals willing to take preventative action against mosquitoes. By methodically investigating best communication practices, this study and others can help practitioners mobilize communities to address large-scale ecological problems. Additionally, the principles outlined here may be transferrable to other communication efforts about ecological issues outside of ZIKV and mosquitoes.

The Aerosphere As A Network Connector Of Organisms And Their Diseases, Jeremy D. Ross, Eli S. Bridge, Diann J. Prosser, John Y. Takekawa

United States Geological Survey: Staff Publications

Aeroecological processes, especially powered flight of animals, can rapidly connect biological communities across the globe. This can have profound consequences for evolutionary diversification, energy and nutrient transfers, and the spread of infectious diseases. The latter is of particular consequence for human populations, since migratory birds are known to host diseases which have a history of transmission into domestic poultry or even jumping to human hosts. In this chapter, we present a scenario under which a highly pathogenic avian influenza (HPAI) strain enters North America from East Asia via postmolting waterfowl migration. We use an agent-based model (ABM) to simulate the …

Detoxification Of Mitochondrial Oxidants And Apoptotic Signaling Are Facilitated By Thioredoxin-2 And Peroxiredoxin-3 During Hyperoxic Injury, Benjamin J. Forred, Darwin R. Daugaard, Brianna K. Titus, Ryan R. Wood, Miranda J. Floen, Michelle L. Booze, Peter F. Vitiello

School of Veterinary and Biomedical Sciences: Faculty Publications

Mitochondria play a fundamental role in the regulation of cell death during accumulation of oxidants. High concentrations of atmospheric oxygen (hyperoxia), used clinically to treat tissue hypoxia in premature newborns, is known to elicit oxidative stress and mitochondrial injury to pulmonary epithelial cells. A consequence of oxidative stress in mitochondria is the accumulation of peroxides which are detoxified by the dedicated mitochondrial thioredoxin system. This system is comprised of the oxidoreductase activities of peroxiredoxin-3 (Prx3), thioredoxin-2 (Trx2), and thioredoxin reductase-2 (TrxR2). The goal of this study was to understand the role of the mitochondrial thioredoxin system and mitochondrial injuries during …

Maternal Inflammation At Mid-Gestation In Pregnant Rats Impairs Fetal Muscle Growth And Development At Term, C. N. Cadaret, K. A. Beede, E. M. Merrick, T. L. Barnes, J. D. Loy, D. T. Yates

School of Veterinary and Biomedical Sciences: Faculty Publications

Intrauterine growth restriction (IUGR) is a leading cause of perinatal morbidity and mortality. Low birth weight resulting from preterm birth and/or IUGR is an underlying factor in 60–80% of perinatal death worldwide, and is particularly common in developing countries (UNICEF, 2008). Furthermore, studies have linked IUGR and the associated fetal malnutrition to increased incidence of metabolic syndrome in adult life (Barker et al., 1993; Godfrey and Barker, 2000). The “thrifty phenotype hypothesis” developed by David Barker (Hales et al., 1991) states that IUGR-associated fetal malnutrition forces the fetus to spare nutrients by altering tissue-specific metabolism in order to survive. In …

A Parapoxviral Virion Protein Targets The Retinoblastoma Protein To Inhibit Nf-Κb Signaling, Ponnuraj Nagendraprabhu, Sushil Khatiwada, Sabal Chaulagain, Gustavo A. Delhon, Daniel L. Rock

School of Veterinary and Biomedical Sciences: Faculty Publications

Poxviruses have evolved multiple strategies to subvert signaling by Nuclear Factor κB (NF-κB), a crucial regulator of host innate immune responses. Here, we describe an orf virus (ORFV) virion-associated protein, ORFV119, which inhibits NF-κB signaling very early in infection (≤30 min post infection). ORFV119 NF-κB inhibitory activity was found unimpaired upon translation inhibition, suggesting that virion ORFV119 alone is responsible for early interference in signaling. A C-terminal LxCxE motif in ORFV119 enabled the protein to interact with the retinoblastoma protein (pRb) a multifunctional protein best known for its tumor suppressor activity. Notably, experiments using a recombinant virus containing an ORFV119 …

A previous report indicated that prototype chlorovirus PBCV-1 replicated in two Chlorella variabilis algal strains, NC64A and Syngen 2-3, that are ex-endosymbionts isolated from the protozoan Paramecium bursaria. Surprisingly, plaque-forming viruses on Syngen 2-3 lawns were often higher than on NC64A lawns from indigenous water samples. These differences led to the discovery of viruses that exclusively replicate in Syngen 2-3 cells, named Only Syngen (OSy) viruses. OSy-NE5, the prototype virus for the proposed new species, had a linear dsDNA genome of 327 kb with 44-nucleotide-long, incompletely base-paired, covalently closed hairpin ends. Each hairpin structure was followed by an identical …

The genomes of OT strains AFSC4 and AFSC7 were similarly sequenced by HTS Since strains AFSC4 (GenBank Accession #: NZ_LYMT00000000.1, https://www.ncbi.nlm.nih.gov/nuccore/1035784408) and AFSC7 (GenBank Accession #: NZ_LYMB00000000.1, https://www.ncbi.nlm.nih.gov/nuccore/1035854767) were more resistant to antibiotics than strain Karp, we conducted comparative analysis of the three draft genomes annotated by RAST server aimed to identify possible genetic bases of difference in microbial antibiotic sensitivity. Intraspecies comparative genomics analysis of the three OT …

Clonal Distribution And Associated Characteristics Of Escherichia Coli Clinical And Surveillance Isolates From A Military Medical Center, Amee R. Manges, Katrin Mende, Clinton K. Murray, Brian D. Johnson, Evgeni V. Sokurenko, Veronika Tchesnokova, James R. Johnson

Uniformed Services University of the Health Sciences

Antimicrobial-resistant Escherichia coli are a concern for military health services. We studied 100 extended-spectrum beta-lactamase (ESBL)-producing and non-producing E. coli clinical and surveillance isolates from military personnel and civilians at Brooke Army Medical Center (2007–2011). Major E. coli lineages, most prominently ST10 (24%), ST131 (16%), and ST648 (8%), were distributed much as reported for other North American populations. ST131, represented mainly by its resistance-associated ST131-H30 clonal subset,was uniquely associated with a clinical origin, regardless of ESBL status. Thus, clonal background predicted resistance phenotype and clinical versus surveillance origin, and these findings could assist military clinicians and epidemiologists.

Best Practice For Screening Adult Patients With Psoriasis For Polyautoimmunity: Celiac Disease, Rheumatoid Arthritis And Crohn’S Disease, Susan Danielle Ashbaugh

Theses and Dissertations

The purpose of this quality improvement project was to determine if screening primary care patients with psoriasis will improve early detection of celiac disease (CD), rheumatoid arthritis, and Crohn’s disease (CrD). The aim of this project is to assess the utility of early screening in patients with psoriasis in order to facilitate earlier diagnosis of CD, RA and CrD, which would consequently initiate earlier treatment and improve long-term patient outcomes. Genetic and population-based studies suggest that individuals with psoriasis have a greater risk of also having CrD, CD or RA, than do individuals without psoriasis. The literature also suggests that …
