Roman L. Hruska U.S. Meat Animal Research Center: Reports

Microbiome studies in animal science using 16S rRNA gene sequencing have become increasingly common in recent years as sequencing costs continue to fall and bioinformatic tools become more powerful and user-friendly. The combination of molecular biology, microbiology, microbial ecology, computer science, and bioinformatics—in addition to the traditional considerations when conducting an animal science study—makes microbiome studies sometimes intimidating due to the intersection of different fields. The objective of this review is to serve as a jumping-off point for those animal scientists less familiar with 16S rRNA gene sequencing and analyses and to bring up common issues and concerns that arise …

Twenty-Four-Month Longitudinal Study Suggests Little To No Horizontal Gene Transfer In Situ Between Third-Generation Cephalosporin-Resistant Salmonella And Third-Generation Cephalosporin-Resistant Escherichia Coli In A Beef Cattle Feedyard, John W. Schmidt, Sarah A. Murray, Aaron M. Dickey, Tommy L. Wheeler, Dayna M. Harhay, Terrance M. Arthur

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Third-generation cephalosporins (3GCs) are preferred treatments for serious human Salmonella enterica infections. Beef cattle are suspected to contribute to human 3GC-resistant Salmonella infections. Commensal 3GC-resistant Escherichia coli are thought to act as reservoirs of 3GC resistance because these strains are isolated more frequently than are 3GC-resistant Salmonella strains at beef cattle feedyards. During each of 24 consecutive months, four samples of pen surface material were obtained from five pens (N = 480) at a Nebraska feedyard to determine to the contribution of 3GC-resistant E. coli to the occurrence of 3GC-resistant Salmonella. Illumina whole genome sequencing was performed, and …

Department of Earth and Atmospheric Sciences: Faculty Publications

A composite 11.82 m-long (9876e-67 cal yr BP) sediment record from Yellowstone Lake, Wyoming was analyzed using a robust set of biological and geochemical proxies to investigate the paleoenvironmental evolution of the lake and its catchment in response to long-term climate forcing. Oxygen isotopes from diatom frustules were analyzed to reconstruct Holocene climate changes, and pollen, charcoal, diatom assemblages, and biogenic silica provided information on terrestrial and limnological responses. The long-term trends recorded in the terrestrial and limnic ecosystems over the last 9800 years reflect the influence of changes in the amplification of the seasonal cycle of insolation on regional …

Revisiting The Tri-Partite Relationship Between An Insurance Carrier, A Policyholder, And An Insurance Defense Attorney, Ross Pesek, Alejandra Ayotitla Cortez

Nebraska Law Bulletin (Selected Issues)

The tripartite relationship between the insured, insurer, and appointed defense counsel poses inherent conflicts of interest and ethical dilemmas. All parties are affected by the problems arising out of the relationship. The insured is in a vulnerable position when they are denied loyal representation and are threatened with financial ruin. Special attention must be placed on the insurer’s obligations to its insured, including completing a reasonable and proper investigation of the claim, providing a defense if the potential for liability exists, timely effecting a reasonable settlement, and giving equal consideration to the insured’s interest.

On the defense counsel’s side, the …

Evidence Of Myomir Regulation Of The Pentose Phosphate Pathway During Mechanical Load-Induced Hypertrophy, Taylor Valentino, Vandre C. Figueiredo, C. Brooks Mobley, John J. Mccarthy, Ivan Jose Vechetti Jr

Department of Nutrition and Health Sciences: Faculty Publications

Many of the molecular and cellular mechanisms discovered to regulate skeletal muscle hypertrophy were first identified using the rodent synergist ablation model. This model reveals the intrinsic capability and necessary pathways of skeletal muscle growth in response to mechanical overload (MOV). Reminiscent of the rapid cellular growth observed with cancer, we hypothesized that in response to MOV, skeletal muscle would undergo metabolic programming to sustain increased demands to support hypertrophy. To test this hypothesis, we analyzed the gene expression of specific metabolic pathways taken from transcriptomic microarray data of a MOV time course. We found an upregulation of genes involved …

Mt10-Cvb3 Vaccine Virus Protects Against Cvb4 Infection By Inducing Cross-Reactive, Antigen-Specific Immune Responses, Ninaad Lasrado, Rajkumar Arumugam, Mahima T. Rasquinha, Meghna Sur, David Steffen, Jay Reddy

School of Veterinary and Biomedical Sciences: Faculty Publications

Group B coxsackieviruses (CVB) containing six serotypes, B1–B6, affect various organs, and multiple serotypes can induce similar diseases such as myocarditis and pancreatitis. Yet, no vaccines are currently available to prevent these infections. Translationally, the derivation of vaccines that offer protection against multiple serotypes is highly desired. In that direction, we recently reported the generation of an attenuated strain of CVB3, termed Mt10, which completely protects against both myocarditis and pancreatitis induced by the homologous wild-type CVB3 strain. Here, we report that the Mt10 vaccine can induce cross-protection against multiple CVB serotypes as demonstrated with CVB4. We note that the …

Global Distribution And Richness Of Armillaria And Related Species Inferred From Public Databases And Amplicon Sequencing Datasets, Rachel A. Koch, Joshua Herr

Department of Plant Pathology: Faculty Publications

Armillaria is a globally distributed fungal genus most notably composed of economically important plant pathogens that are found predominantly in forest and agronomic systems. The genus sensulato has more recently received attention for its role in woody plant decomposition and in mycorrhizal symbiosis with specific plants. Previous phylogenetic analyses suggest that around 50 species are recognized globally. Despite this previous work, no studies have analyzed the global species richness and distribution of the genus using data derived from fungal community sequencing datasets or barcoding initiatives. To assess the global diversity and species richness of Armillaria, we mined publicly available sequencing …

Exposure Of Predatory And Scavenging Birds To Anticoagulant Rodenticides In France: Exploration Of Data From French Surveillance Programs, Meg-Anne Moriceau, Sébastien Lefebvre, Isabelle Fourel, Etienne Benoit, Florence Buronfosse-Roque, Pascal Orabi, Barnett A. Rattner, Virginie Lattard

United States Geological Survey: Staff Publications

Wild raptors are widely used to assess exposure to different environmental contaminants, including anticoagulant rodenticides (ARs). ARs are used on a global scale for rodent control, and act by disruption of the vitamin K cycle that results in haemorrhage usually accompanied by death within days. Some ARs are highly persistent and bioaccumulative, which can cause significant exposure of non-target species.We characterized AR exposure in a heterogeneous sample of dead raptors collected over 12 years (2008–2019) in south-eastern France. Residue analysis of 156 liver samples through LC-MS/MS revealed that 50% (78/156) were positive for ARs, with 13.5% (21/156) having summed second-generation …

Issue Of False Amphetamine Field Test Positives Caused By Sugar: Use Of Baeyer Test As A Secondary Test Solution, Reed A. Knutson, Jennah Duncan, Kara Peightal, Samuel Thomas

Department of Chemistry: Dissertations, Theses, and Student Research

The Marquis reagent is a well-established and widely used chemical presumptive test for 3,4-Methylenedioxymethamphetamine (MDMA) and methamphetamine. It is composed of concentrated sulfuric acid and 40% formaldehyde, which act upon alkaloids causing them to complex into larger molecules. This complexation causes a color change that can be visually interpreted as a positive or negative result. Almost any sugar molecule can be complexed in this way as well, due to their many OH groups. Experimentally it was found that the sugar molecules did complex with one another when the Marquis test was administered. The color produced by this reaction was brownish-red. …

Higher Sound Levels In K-12 Classrooms Correlate To Lower Math Achievement Scores, Laura Caroline Brill, Lily M. Wang

Durham School of Architectural Engineering and Construction: Faculty Publications

Sound levels from occupied classrooms have been gathered from 220 classrooms across four grade levels (3, 5, 8 and 11) over six school days each and processed with k-means clustering into speech and non-speech clusters. Three metrics describing the classroom acoustics, including the average daily A-weighted equivalent level for non-speech, the average daily difference between the A-weighted equivalent levels for speech and nonspeech (a signal to noise ratio), and the mid-frequency averaged reverberation time, were analyzed against classroom-aggregated standardized reading and math achievement test scores, while controlling for classroom demographics including socioeconomic status. Interactions between the metrics and demographics were …

Vascular Endothelial Growth Factor A 165 Rescues Steroids, Inflammation And Follicle Arrest In High Androstenedione Cows, Mohamed A. Abedal-Majed, Shelby A. Springman, Courtney M. Sutton, Alexandria P. Snider, Brooke E. Bell, Mariah Hart, Scott G. Kurz, Jeffrey Bergman, Adam F. Summers, Renee M. Mcfee, John S. Davis, Jennifer R. Wood, Andrea S. Cupp

Department of Animal Science: Faculty Publications

A population of cows with excess androstenedione (A4; High A4) in follicular fluid, with follicular arrest, granulosa cell dysfunction, and a 17% reduction in calving rate was previously identified. We hypothesized that excess A4 in the ovarian microenvironment caused the follicular arrest in High A4 cows and that vascular endothelial growth factor A would rescue the High A4 phenotype. In trial 1, prior to culture, High A4 ovarian cortex (n=9) had greater numbers of early stage follicles (primordial) and fewer later-stage follicles compared to controls (n=11). Culture for 7 days did not relieve this follicular arrest; …

Adaptive Selection Signatures In River Buffalo With Emphasis On Immune And Major Histocompatibility Complex Genes, Yan Ren, Callum Macphillamy, Thu Hien To, Timothy P. L. Smith, John L. Williams, Wai Yee Low

Roman L. Hruska U.S. Meat Animal Research Center: Reports

River buffalo is an agriculturally important species with many traits, such as disease tolerance, which promote its use worldwide. Highly contiguous genome assemblies of the river buffalo, goat, pig, human and two cattle subspecies were aligned to study gene gains and losses and signs of positive selection. The gene families that have changed significantly in river buffalo since divergence from cattle play important roles in protein degradation, the olfactory receptor system, detoxification and the immune system. We used the branch site model in PAML to analyse single-copy orthologs to identify positively selected genes that may be involved in skin differentiation, …

Salient Experiences In Student Development: Impact Of An Undergraduate Stem Teacher Preparation Program, Amie S. Sommers, Kelly Gomez Johnson, Paula Jakopovic, Julio Rivera, Neal Grandgenett, John A. Conrad, William E. Tapprich, Christine E. Cutucache

School of Natural Resources: Faculty Publications

The need for a comprehensive, high-quality pipeline for the development of undergraduate pre-service teachers, especially those that represent a diverse student body, within STEM disciplines is acute. Here, we studied the NoyceSCIENCE program to determine the most impactful experiences offered to undergraduates through the lens of student development theory. We used qualitative coding to analyze data collected from journals (n = 29) written by students of varying backgrounds, and at varying levels within the program (i.e., the Scholar and Intern level) over a 3-year program running period. We observed that faculty mentorship, the ability of undergraduates to mentor others, volunteer …

Evaluating Large Spontaneous Deletions In A Bovine Cell Line Selected For Bovine Viral Diarrhea Virus Resistance, Aspen M. Workman, Michael P. Heaton, Dennis A. Webster, Gregory P. Harhay, Theodore S. Kalbfleisch, Timothy P.L. Smith, Shollie M. Falkenberg, Daniel F. Carlson, Tad S. Sonstegard

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Bovine viral diarrhea virus’s (BVDV) entry into bovine cells involves attachment of virions to cellular receptors, internalization, and pH-dependent fusion with endosomal membranes. The primary host receptor for BVDV is CD46; however, the complete set of host factors required for virus entry is unknown. The Madin-Darby bovine kidney (MDBK) cell line is susceptible to BVDV infection, while a derivative cell line (CRIB) is resistant at the level of virus entry. We performed complete genome sequencing of each to identify genomic variation underlying the resistant phenotype with the aim of identifying host factors essential for BVDV entry. Three large compound deletions …

Information Extraction And Classification On Journal Papers, Lei Yu

School of Computing: Dissertations, Theses, and Student Research

The importance of journals for diffusing the results of scientific research has increased considerably. In the digital era, Portable Document Format (PDF) became the established format of electronic journal articles. This structured form, combined with a regular and wide dissemination, spread scientific advancements easily and quickly. However, the rapidly increasing numbers of published scientific articles requires more time and effort on systematic literature reviews, searches and screens. The comprehension and extraction of useful information from the digital documents is also a challenging task, due to the complex structure of PDF.

Investigation Of The Prevalence Of Faults In The Heating, Ventilation, And Air-Conditioning Systems Of Commercial Buildings, Amir Ebrahimifakhar

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

This dissertation describes a large-scale investigation of heating, ventilation, and air-conditioning (HVAC) fault prevalence in commercial buildings in the United States. A multi-year dataset with 36,556 pieces of HVAC equipment including air handling units (AHUs), air terminal units (ATUs), and packaged rooftop units (RTUs) was analyzed to determine values for several HVAC fault prevalence metrics. The primary source of data for this study comes from three commercial fault detection and diagnostics (FDD) providers. Since each FDD provider uses different terms to refer to the same fault in an HVAC system, a mapping function was created for each FDD provider’s dataset, …

Cognitive Effects Of Alcohol Use And Sleep Disruption In College Students, Taylor English

Department of Psychology: Dissertations, Theses, and Student Research

Alcohol use and sleep disruption are highly prevalent amongst college students, yet their combined effects on cognitive functioning and subsequent classroom performance have not been fully examined. Alcohol use has been shown to negatively impact cognitive functioning, especially in college students without fully matured brain regions. This has led to decreases in academic functioning and increases in college dropout. Disruptions in sleep functioning can lead to both lapses in attention and an overall decrease in attention, which can negatively impact learning in a classroom environment.

Participants were 96 undergraduate students who were invited to participate based on responses from a …

Assessing Deep Convection Initiation In A Mountain-Valley System Using Unoccupied Aircraft System Observations, Alexander Erwin

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Forecasts of the timing and location of deep convection are inadequate, as are scientists’ understanding of the dominant controlling mechanisms. The Lower Atmosphere Process Studies at Elevation, a Remotely-piloted Aircraft Team Experiment (LAPSE-RATE) field campaign, which took place in the San Luis Valley (SLV) of Colorado during July 2018, aimed to use in-situ observations to develop a deeper understanding of the processes relevant to deep convection initiation (DCI). The campaign resulted in a unique dataset, collected by a network of unoccupied aircraft systems (UAS) in a unique geographic setting, which can be used to examine the impact of terrain and …

Open Data Practices Among Users Of Primary Biodiversity Data, Caitlin P. Mandeville

Harold W. Manter Laboratory of Parasitology: Library Materials

Presence-only biodiversity data are increasingly relied on in biodiversity, ecology, and conservation research, driven by growing digital infrastructures that support open data sharing and reuse. Recent reviews of open biodiversity data have clearly documented the value of data sharing, but the extent to which the biodiversity research community has adopted open data practices remains unclear. We address this question by reviewing applications of presence-only primary biodiversity data, drawn from a variety of sources beyond open databases, in the indexed literature. We characterize how frequently researchers access open data relative to data from other sources, how often they share newly generated …

Rooting Out Genetic Structure Of Invasive Wild Pigs In Texas, Anna M. Mangan, Antoinette J. Piaggio, Michael J. Bodenchuk, Courtney F. Pierce, Timothy J. Smyser

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive wild pigs (Sus scrofa), also called feral swine or wild hogs, are recognized as among the most destructive invasive species in the world. Throughout the United States, invasive wild pigs have expanded rapidly over the past 40 years with populations now established in 38 states. Of the estimated 6.9 million wild pigs distributed throughout the United States, Texas supports approximately 40% of the population and similarly bears disproportionate ecological and economic costs. Genetic analyses are an effective tool for understanding invasion pathways and tracking dispersal of invasive species such as wild pigs and have been used recently …

Soil Hydrologic Grouping Guide Which Soil And Weather Properties Best Estimate Corn Nitrogen Need, Gregory Mac Bean, Curtis J. Ransom, Newell R. Kitchen, Peter C. Scharf, Kristen S. Veum, James J. Camberato, Richard B. Ferguson, Fabián G. Fernández, David W. Franzen, Carrie A.M. Laboski, Emerson D. Nafziger, John E. Sawyer, Robert L. Nielsen

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Nitrogen fertilizer recommendations in corn (Zea mays L.) that match the economically optimal nitrogen fertilizer rate (EONR) are imperative for profitability and minimizing environmental degradation. However, the amount of soil N available for the crop depends on soil and weather factors, making it difficult to know the EONR from year-to-year and from field-to-field. Our objective was to explore, within the framework of hydrologic soil groups and drainage classifications (HGDC), which site-specific soil and weather properties best estimated corn N needs (i.e., EONR) for two application timings (at-planting and side-dress). Included in this investigation was a validation step using an independent …

Wildlife Responses To Livestock Guard Dogs And Domestic Sheep On Open Range, Daniel Kinka, Jeffrey T. Schultz, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Domestic sheep (Ovis aries) are an attractant to carnivores; however, sheep are often accompanied by humans and livestock guardian dogs (LGDs; Canis familiaris), which defend sheep from depredation. Sheep also compete directly with wildlife for grazing resources. Although practiced for millennia in much of the world outside North America, the effect that transhumance has on wildlife is poorly understood. To test the effect of sheep bands (sheep, humans, and LGDs) on wildlife, we modeled the detection probability of wild mammals relative to the presence of sheep bands in the Northwestern United States. Sheep band presence was associated …

Two New Species Of Hermeuptychia From North America And Three Neotype Designations (Nymphalidae: Satyrinae), Qian Cong, Eduardo P. Barbosa, Mario A. Marín, André V. L. Freitas, Gerardo Lamas, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Abstract

Two new species of Hermeuptychia Forster, 1964 are described. Hermeuptychia sinuosa Grishin, sp. n. (type locality Guatemala: El Progreso, Morazán) is an isolated member of the genus that does not readily fit into known species groups, as suggested by its distinct male and female genitalia and COI DNA barcode sequences. It is distinguished from its congeners by prominently wavy submarginal lines, rounder wings and distinctive genitalia, and can typically be identified by a white dot, instead of an eyespot, near the ventral hindwing apex. Hermeuptychia occidentalis Grishin, sp. n. (type locality Mexico: Guerrero, Acapulco) belongs to the Hermeuptychia sosybius …
