Avian Host-Selection By Culex Pipiens In Experimental Trials, Jennifer E. Simpson, Corrine M. Folsom-O’Keefe, James E. Childs, Leah E. Simons, Theodore G. Andreadis, Maria A. Diuk-Wasser

Zoonotics and Wildlife Disease: Publications

Evidence from field studies suggests that Culex pipiens, the primary mosquito vector of West Nile virus (WNV) in the northeastern and north central United States, feeds preferentially on American robins (Turdus migratorius). To determine the contribution of innate preferences to observed preference patterns in the field, we conducted host preference trials with a known number of adult female C. pipiens in outdoor cages comparing the relative attractiveness of American robins with two common sympatric bird species, European starling, Sternus vulgaris and house sparrow, Passer domesticus. Host seeking C. pipiens were three times more likely to enter robin-baited …

Antemortem Detection Of PrpCwd In Preclinical, Ranch-Raised Rocky Mountain Elk (Cervus Elaphus Nelsoni) By Biopsy Of The Rectal Mucosa, Terry R. Spraker, Kurt C. Vercauteren, Thomas Gidlewski, David A. Schneider, Randy Munger, Aru Balachandran, Katherine I. O'Rourke

Zoonotics and Wildlife Disease: Publications

Antemortem biopsy of the rectal mucosa was evaluated as a method for the preclinical diagnosis of chronic wasting disease (CWD) in a herd of ranch-raised Rocky Mountain elk (Cervus elaphus nelsoni) quarantined because of exposure to CWD. Biopsy samples were obtained from 41 elk during the winter of 2005–2006 and from 26 elk from that herd still alive and available for testing during the winter of 2006–2007. Samples were examined for PrP^CWD, the protein marker for CWD infection, by immunohistochemistry. PrP^CWD was detected in follicles of the rectoanal mucosa-associated lymphoid tissue in biopsy samples from …

Ksiazek, William R. White, Michael T. Mcintosh

Zoonotics and Wildlife Disease: Publications

Since the discovery of the Marburg and Ebola species of filovirus, seemingly random, sporadic fatal outbreaks of disease in humans and nonhuman primates have given impetus to identification of host tropisms and potential reservoirs. Domestic swine in the Philippines, experiencing unusually severe outbreaks of porcine reproductive and respiratory disease syndrome, have now been discovered to host Reston ebolavirus (REBOV). Although REBOV is the only member of Filoviridae that has not been associated with disease in humans, its emergence in the human food chain is of concern. REBOV isolates were found to be more divergent from each other than from the …

Superhalogen Properties Of Cufn Clusters, Q. Wang, Q. Sun, P. Jena

Physics Publications

A first-principles calculation based on gradient corrected density functional theory reveals unusual properties of a Cu atom interacting with F. Up to six F atoms are bound to a single Cu atom with electron affinities steadily rising as successive F atoms are attached, reaching a peak value of 7.2 eV in CuF5. The large energy gaps between the highest occupied and lowest unoccupied molecular orbitals, both in neutral and anionic form, provide further evidence of their stability. These unusual properties brought about by involvement of inner shell 3d-electrons not only allow CuFn to belong to the class of superhalogens but …

Proteomic And Network Analysis Characterize Stage-Specific Metabolism In Trypanosoma Cruzi, Seth B. Roberts, Jennifer L. Robicahux, Arvind K. Chavali, Patricio A. Manque, Vladimir Lee, Ana M. Laura, Jason A. Papin, Gregory A. Buck

Study of Biological Complexity Publications

Background

Trypanosoma cruzi is a Kinetoplastid parasite of humans and is the cause of Chagas disease, a potentially lethal condition affecting the cardiovascular, gastrointestinal, and nervous systems of the human host. Constraint-based modeling has emerged in the last decade as a useful approach to integrating genomic and other high-throughput data sets with more traditional, experimental data acquired through decades of research and published in the literature.

Results

We present a validated, constraint-based model of the core metabolism of Trypanosoma cruzistrain CL Brener. The model includes four compartments (extracellular space, cytosol, mitochondrion, glycosome), 51 transport reactions, and 93 metabolic reactions …

Disparities In Adl And Iadl Disabilities Among Elders Of Hispanic Subgroups In The United States: Results From The National Health Interview Survey 2001-2003, Alberto Coustasse, Sejong Bae, Cody Arvidson, Karan P. Singh, Fernando Trevino

Management Faculty Research

The authors compared disability and functional limitation among elder Hispanic subgroups by using data from the 2001-2003 National Health Interview Survey (National Center for Health Statistics 2008a). The authors applied chi-square analysis for bivariate comparisons and used multiple logistic regression analyses for making comparisons, estimating odds ratios, and predicting disabilities. Results revealed a 21.4% rate of disability of any type in Hispanics. Puerto Ricans reported the highest rates of Activity of Daily Living (ADL) and Instrumental Activity of Daily Living (IADL) disabilities compared with other Hispanic subgroups (Mexicans, Cubans, Central and South Americans) and reported a higher rate than did …

Disparities In Disability Among Non-Hispanic Black Elders: Results From The National Interview Survey 2001–2003, Alberto Coustasse, Dennis Emmett, Nimisha Patel, Alicia Pekar

Management Faculty Research

A drastically increasing elderly population and disparity among disability poses a concern for the US health care industry. This retrospective cross-sectional study analyzed whether ADL and IADL disabilities were different among non-Hispanic white (NHW) and non-Hispanic black (NHB) populations age 65 and over. Data was retrieved from the 2001–2003 National Health Interview Survey (NHIS) for comparing NHBs and NHWs using chi-square analysis for bivariate comparisons. For both elderly NHBs and elderly NHWs, increased rates of disability were reported for being over 75, female, single, and having lower education. NHBs reported statistically higher disability rates for ADL, IADL, and for any …

Development Of The Innate Immune Response In Nestlingtree Swallows (Tachycineta Bicolor), T.R. Stambaugh

McNair Scholars Journal

The innate immune system provides an immediate, short term, first line of defense from pathogens; its appearance early in development in vertebrates is evidence of its critical importance. Even so, few studies have investigated the development of the immune response as juveniles transition into adults. Ultimately, the ability to respond to pathogens confers fitness benefits in terms of health, survival, and reproductive success, and it follows that functions such as rapid growth cannot be fully met simultaneously since energy is a limiting resource. As a result, defense mechanisms are compromised at an early age due to energy allocation to rapid …

A Comparison Of Cationic Surfactant Immobilized Ion Exchange Membranes In Their Application For Use In Extraction Of 4-Nitophenol, Robert Derrek Brown

Mahurin Honors College Capstone Experience/Thesis Projects

Solid Phase Extraction has replaced distillation and liquid-liquid extraction as the most widely used method for extraction from solution. Though traditional SPE has seen great success, its downfalls are that it requires meticulous preparation procedures requiring funtionalized silanes and silica or polymerization courses. An alternative is ion exchange membranes to which long carbon chain ionic surfactants have been attached. The S1000 membrane ion exchange capacity was measured to be approximately 110 micro-equil/disc while the P81 membrane was 150 micro-equil/disc. Octadecyltri-methylammonium surfactant was immobilized on the membrane surface, qualitated through the use of ATR-FTIR, and quantified through elemental analysis. Kinetic adsorption …

Remote Sensing For Prediction Of 1-Year Post-Fire Ecosystem Condition, Leigh B. Lentile, Alistair M.S. Smith, Andrew T. Hudak, Penelope Morgan, Michael J. Bobbitt, Sarah A. Lewis, Pete Robichaud

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Appropriate use of satellite data in predicting >1 year post-fire effects requires remote measurement of surface properties that can be mechanistically related to ground measures of post-fire condition. The present study of burned ponderosa pine (Pinus ponderosa) forests in the Black Hills of South Dakota evaluates whether immediate fractional cover estimates of char, green vegetation and brown (non-photosynthetic) vegetation within a pixel are improved predictors of 1-year post-fire field measures, when compared with single-date and differenced Normalized Burn Ratio (NBR and dNBR) indices. The modeled estimate of immediate char fraction either equaled or outperformed all other immediate metrics …

Water Availability Directly Determines Per Capita Consumption At Two Trophic Levels, Kevin E. Mccluney, John L. Sabo

Biological Sciences Faculty Publications

Community ecology has long focused on energy and nutrients as currencies of species interactions. Evidence from physiological ecology and recent studies suggest that in terrestrial systems, water may influence animal behavior and global patterns of species richness. Despite these observations, water has received little attention as a currency directly influencing animal species interactions. Here, we show that the per capita interaction strength between predatory wolf spiders and their primary prey, field crickets, is strong (0.266) when predators and prey are maintained in ambient dry conditions, but is near zero (0.001) when water is provided ad libitum. Moreover, crickets consume 31-fold …

Ethical Considerations Of Genetic Presymptomatic Testing For Huntington's Disease, Alberto Coustasse, Alicia Pekar, Andrew Sikula Sr., Sue Lurie

Management Faculty Research

The aim of this literature review was to determine if there is adequate ethical justification for presymptomatic genetic testing on potential Huntington's disease patients. Huntington's disease is a neurological genetic disorder characterized by midlife onset which consists of cognitive, physical, and emotional deterioration. Although genetic testing has traditionally been guided by the principle of autonomy, severe psychological consequences such as depression, anxiety, survival guilt, and suicide have complicated the ethical issue of providing a presymptomatic yet definitive diagnosis for an incurable disease. An analysis of available articles yielded inconclusive findings, namely due to insufficient evidence, self-selection bias of test participants, …

Structured Decision Making As A Conceptual Framework To Identify Thresholds For Conservation And Management, Julien Martin, Michael C. Runge, James D. Nichols, Bruce C. Lubow, William L. Kendall

United States Geological Survey: Staff Publications

Thresholds and their relevance to conservation have become a major topic of discussion in the ecological literature. Unfortunately, in many cases the lack of a clear conceptual framework for thinking about thresholds may have led to confusion in attempts to apply the concept of thresholds to conservation decisions. Here, we advocate a framework for thinking about thresholds in terms of a structured decision making process. The purpose of this framework is to promote a logical and transparent process for making informed decisions for conservation.

Specification of such a framework leads naturally to consideration of definitions and roles of different kinds …

Isolation Of Fungi From Lake Vostok Accretion Ice, Scott O. Rogers, Tom D'Elia, Ram Veerapaneni, Vincent Theraisnathan

Biological Sciences Faculty Publications

Here we report the characterization of fungi from 10 accretion ice sections (3300-5100 y old) as well as two deep glacial ice sections that are close to the bottom of the glacier (1 000 000-2 000 000 y old) from the Vostok, Antarctica, 5G ice core. Fungi were characterized by fluorescence microscopy culturing and sequence analyses of ribosomal DNA internal transcribed spacers. A total of 270 fungal colonies were cultured from the accretion ice of subglacial Lake Vostok and an additional 14 from the glacial ice immediately above the accretion ice. Mean concentrations were 0-4.42 cells mL-1 ice meltwater of …
