Perches As Cooling Devices For Reducing Heat Stress In Caged Laying Hens: A Review, Jiaying Hu, Yijie Xiong

Department of Animal Science: Faculty Publications

Heat stress is one of the most detrimental environmental challenges affecting the biological process and the related production performance of farm animals, especially in poultry. Commercial laying hens have been bred (selected) for high egg production, resulting in increased sensitivity to heat stress due to breeding-linked metabolic heat production. In addition, laying hens are prone to heat stress due to their inadequate species-specific cooling mechanisms resulting in low heat tolerance. In addition, hens have no sweat glands and feathering covers almost their entire body to minimize body heat loss. The poultry industry and scientists are developing cooling methods to prevent …

Inheritance Of A Mutation Causing Neuropathy With Splayed Forelimbs In Jersey Cattle, A. Al-Khudhair, D. J. Null, J. B. Cole, C. W. Wolfe, David J. Steffen, P. M. Vanraden

School of Veterinary and Biomedical Sciences: Faculty Publications

A new undesirable genetic factor, neuropathy with splayed forelimbs (JNS), has been identified recently in the Jersey breed. Calves affected with JNS are unable to stand on splayed forelimbs that exhibit significant extensor rigidity and excessive lateral abduction at birth. Affected calves generally are alert at birth but exhibit neurologic symptoms, including spasticity of head and neck and convulsive behavior. Other symptoms reported include dislocated shoulders, congenital craniofacial anomalies, and degenerative myelopathy. Inheritance of an undesirable genetic factor was determined from a study of 16 affected calves reported by Jersey breeders across the United States. All of their pedigrees traced …

Domarchive: A Century Of Published Dominance Data, Eli D. Strauss, Alex R. Decasien, Gabriela Galindo, Elizabeth A. Hobson, Daizaburo Shizuka, James P. Curley

School of Biological Sciences: Faculty Publications

Dominance behaviours have been collected for many groups of animals since 1922 and serve as a foundation for research on social behaviour and social structure. Despite a wealth of data from the last century of research on dominance hierarchies, these data are only rarely used for comparative insight. Here, we aim to facilitate comparative studies of the structure and function of dominance hierarchies by compiling published dominance interaction datasets from the last 100 years of work. This compiled archive includes 436 datasets from 190 studies of 367 unique groups (mean group size 13.8, s.d. = 13.4) of 135 different species, …

The Legacy Book In America, 1664–1792, Roxanne Harde, Lindsay Yakimyshyn

Zea E-Books Collection

Legacy books in colonial America were instruments for the transmission of cultural values between generations: the dying mother (usually) instructing and advising children on the path to salvation and heavenly reunions. They were a popular and influential form of women’s discourse that distilled the ideologies of the religious establishment into practical and emotional lessons for lay persons, especially the young.

This collection draws together legacy texts written by colonial American women and girls: five mother’s legacy books and two legacies by children, organized here chronologically. These legacies were writ­ten in anticipation of dying, making awareness of death central to the …

Exploring The Association Between Anticipated And Actual Responses To Disclosures Of Intimate Partner Violence And Sexual Assault, Emily A. Waterman, Emily R. Dworkin, Christina M. Dardis, Sarah E. Ullman, Katie M. Edwards, Lindsey M. Rodriguez

Department of Educational Psychology: Faculty Publications

Victims of intimate partner violence (IPV) and sexual assault (SA) commonly disclose their experiences to friends or family members, or within other personal relationships. Disclosure recipients’ responses to these disclosures are associated with victims’ mental health. Previous research has separately measured both actual responses to IPV/SA and anticipated responses to IPV/SA (e.g., response to a hypothetical scenario) from the perspective of disclosure recipients. Yet, little research has described the association between disclosure recipients’ anticipated and actual responses. The aim of the current paper was to use a prospective design to examine the association between disclosure recipients’ anticipated and actual responses …

Profile Of Producers And Production Of Dry-Aged Beef In Brazil, Jonatã Henrique Rezende-De-Souza, Flavio Andre Bolini Cardello, Ana Paula Moraes De Paula, Felipe A. Ribeiro, Chase C. Calkins, Sérgio Bertelli Pflanzer

Department of Animal Science: Faculty Publications

No information is currently available on the profile of producers and production process of dry-aged beef in Brazil, to the best of the authors’ knowledge. We surveyed 37 Brazilian companies that were producing dry-aged beef in 2020 to investigate this market. The absolute and relative frequency of responses was calculated to obtain the sum, average, minimum, and maximum values. From the respondents, dry-aged beef was first produced in 2009, and most producers are located in big cities. Most respondents control and monitor chamber temperature; however, humidity and air velocity only are monitored. The aging period (mostly between 22 to 60 …

Fu brick tea (FBT) is one of the major brands of dark tea. Microbial fermentation is considered the key step in the development of the special characteristics of FBT. The systemic corelationship of the microbiome and metabolomics during manufacture of Fu brick tea is not fully understood. In this study, we comprehensively explored the microbiome and metabolite dynamic evolution during the FBT manufacturing processes, and revealed decisive factors for the quality and safety of FBT based on the grouped methods of metabolomics combined with biochemical measurements, microbiome sequencing combined with quantitative polymerase chain reaction (PCR), and multiplex analysis. Both the …

A Survey Of Researchers’ Needs And Priorities For Data Sharing, Iain Hrynaszkiewicz, James Harney, Lauren Cadwallader

Copyright, Fair Use, Scholarly Communication, etc.

One of the ways in which the publisher PLOS supports open science is via a stringent data availability policy established in 2014. Despite this policy, and more data sharing policies being introduced by other organizations, best practices for data sharing are adopted by a minority of researchers in their publications. Problems with effective research data sharing persist and these problems have been quantified by previous research as a lack of time, resources, incentives, and/or skills to share data.

In this study we built on this research by investigating the importance of tasks associated with data sharing, and researchers’ satisfaction with …

Localization Of Kisspeptin, Nkb, And Nk3r In The Hypothalamus Of Gilts Treated With The Progestin Altrenogest, Ashley N. Lindo, Jennifer F. Thorson, Michelle N. Bedenbaugh, Richard B. Mccosh, Justin A. Lopez, Samantha A. Young, Lanny J. Meadows, Elizabeth C. Bowdridge, Chrysanthi Fergani, Bradley A. Freking, Michael N. Lehman, Stanley M. Hileman, Clay A. Lents

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

Mechanisms in the brain controlling secretion of gonadotropin hormones in pigs, particularly luteinizing hormone (LH), are poorly understood. Kisspeptin is a potent LH stimulant that is essential for fertility in many species, including pigs. Neurokinin B (NKB) acting through neurokinin 3 receptor (NK3R) is involved in kisspeptin-stimulated LH release, but organization of NKB and NK3R within the porcine hypothalamus is unknown. Hypothalamic tissue from ovariectomized (OVX) gilts was used to determine the distribution of immunoreactive kisspeptin, NKB, and NK3R cells in the arcuate nucleus (ARC). Almost all kisspeptin neurons coexpressed NKB in the porcine ARC. Immunostaining for NK3R was distributed …

Impact Of Feeding Syngenta Enogen® Feed Corn Compared To Control Corn In Different Diet Scenarios To Finishing Beef Cattle, Stacia M. Volk, Hannah H. Wilson, Kathryn J. Hanford, James C. Macdonald, Galen E. Erickson

Department of Animal Science: Faculty Publications

The objective of this pooled statistical analysis was to evaluate Syngenta Enogen® Feed Corn (EFC) versus conventional corn (CON) when fed as either dry-rolled corn (DRC) or highmoisture corn (HMC) for effects on finishing beef cattle performance and carcass characteristics. Corns were evaluated in diets with byproduct inclusion rates of 0, 15, 18, 20, and 30% distiller grains or 25 and 35% Sweet Bran® (a commercial corn gluten feed product). Seven trials (n = 1856) consisting of 200 pen means comparing 26 diet treatments were analyzed using regression in a pooled analysis. When EFC was processed as DRC, the gain …

Output Consistency Scale To Standardize Ostomate Output Description In Clinical Practice And Studies, Lisa Whisenhunt, Linda Xu, Fan Yang, Jacques Izard

Food for Health: Publications

Stool descriptors have become popular due to the large diffusion of the Bristol Stool Form Scale (BSFS) via clinical studies, clinical trials, and social media. The applications have been numerous and centered around standardization of terminology that can be used by health care professionals and patients alike, as well as individuals interested in their wellness and the associated partners in the wellness industry. For a portion of the population, the digestive content is rerouted to an external manufactured pouch or bag, making the use of the BSFS visual descriptors of stool difficult. From day one post-resection surgery, ostomates are challenged …

Assemblages Of Acari In Shallow Burials: Mites As Markers Of The Burial Environment, Of The Stage Of Decay And Of Body‑Cadaver Regions, Jas K. Rai, Brian J. Pickles, M. Alejandra Perotti

Harold W. Manter Laboratory of Parasitology: Library Materials

The burial of a cadaver results in reduced arthropod activity and disruptions in colonisation patterns. Here, the distribution and diversity of mite taxa was studied across decomposition stages of shallowly buried pig carcasses (Sus scrofa domesticus). In total 300 mites (88 species) were collected from three pig shallow graves compared to 129 mites (46 species) from control (bare) soil samples at the same depth. A successional pattern of Acari higher taxa and families was observed, and species richness and biodiversity fluctuated throughout decomposition, whereas active decay showed the greatest biodiversity. Mesostigmata mites were the most abundant in ‘cadaver …

Time Management, Megan Paul

Umbrella Summaries

What is time management?

The definition of time management varies across disciplines, researchers, and practitioners. In the context of workplace research, one suggested definition is “behaviours that aim at achieving an effective use of time while performing certain goal-directed activities” (Claessens et al., 2007, p. 262). Another is “a form of decision making used by individuals to structure, protect, and adapt their time to changing conditions” (Aeon & Aguinis, 2017, p. 311). Most research on time management has used self-report measures; diaries and ratings by others (e.g., supervisors) are used much less frequently. Of the self-report measures, no one measure …

The Novel Orfv Protein Orfv113 Activates Lpa-P38 Signaling, Sushil Khatiwad, Gustavo Delho, Sabal Chaulagai, Daniel L. Rock

School of Veterinary and Biomedical Sciences: Faculty Publications

Viruses have evolved mechanisms to subvert critical cellular signaling pathways that regulate a wide range of cellular functions, including cell differentiation, proliferation and chemotaxis, and innate immune responses. Here, we describe a novel ORFV protein, ORFV113, that interacts with the G protein-coupled receptor Lysophosphatidic acid receptor 1 (LPA₁). Consistent with its interaction with LPA₁, ORFV113 enhances p38 kinase phosphorylation in ORFV infected cells in vitro and in vivo, and in cells transiently expressing ORFV113 or treated with soluble ORFV113. Infection of cells with virus lacking ORFV113 (OVIA82Δ113) significantly decreased p38 phosphorylation and viral plaque size. …

Department of Biochemistry: Faculty Publications

ATP:cob(I)alamin adenosyltransferase (EutT) of Salmonella enterica was overproduced and enriched to ~70% homogeneity, and its basic kinetic parameters were determined. Abundant amounts of EutT protein were produced, but all of it remained insoluble. Soluble active EutT protein (~70% homogeneous) was obtained after treatment with detergent. Under conditions in which cobalamin (Cbl) was saturating, K_m(ATP) = 10 μM, k_cat = 0.03 s^–1, and V_max = 54.5 nM min^–1. Similarly, under conditions in which MgATPwas saturating,K_m(Cbl)= 4.1μM, k_cat = 0.06 s^–1, andV_{max …}

Multiracial Individuals And Educational Testing, Karen Alexander

The Nebraska Educator: A Student-Led Journal

A literature review focused on quantitative measures and methods regarding multiracial individuals and educational testing revealed that multiracial individuals are uniquely different than monoracial individuals in terms of their racial identity and these unique identities interact with test scores. Until recently, this uniqueness has been ignored by institutions and within the field of educational testing. The uniqueness of multiracial identity should be taken into consideration when using test measures to make decisions for selection and when comparing group outcomes. The review provides a brief picture regarding the history of categorization of multiracial individuals and current research which connects the multiracial …

Assessing The Vegetation Condition Impacts Of The 2011 Drought Across The U.S. Southern Great Plains Using The Vegetation Drought Response Index (Vegdri), Tsegaye Tadesse, Brian D. Wardlow, Jesslyn F. Brown, Mark D. Svoboda, Michael J. Hayes, Brian Fuchs, Denise Gutzmer

National Drought Mitigation Center: Faculty Publications

The vegetation drought response index (VegDRI), which combines traditional climate- and satellite-based approaches for assessing vegetation conditions, offers new insights into assessing the impacts of drought from local to regional scales. In 2011, the U.S. southern Great Plains, which includes Texas, Oklahoma, and New Mexico, was plagued by moderate to extreme drought that was intensified by an extended period of recordbreaking heat. The 2011 drought presented an ideal case study to evaluate the performance of VegDRI in characterizing developing drought conditions. Assessment of the spatiotemporal drought patterns represented in the VegDRI maps showed that the severity and patterns of the …

Defining The Innate Immune Responses For Sars-Cov-2-Human Macrophage Interactions, Mai M. Abdelmoaty, Pravin Yeapuri, Jatin Machhi, Katherine E. Olson, Farah Shahjin, Vikas Kumar, You Zhou, Jingjing Liang, Kabita Pandey, Arpan Acharya, Siddappa N. Byrareddy, R. Lee Mosley, Howard E. Gendelman

Nebraska Center for Biotechnology: Faculty and Staff Publications

Host innate immune response follows severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and it is the driver of the acute respiratory distress syndrome (ARDS) amongst other inflammatory end-organ morbidities. Such life-threatening coronavirus disease 2019 (COVID-19) is heralded by virus-induced activation of mononuclear phagocytes (MPs; monocytes, macrophages, and dendritic cells). MPs play substantial roles in aberrant immune secretory activities affecting profound systemic inflammation and end-organ malfunctions. All follow the presence of persistent viral components and virions without evidence of viral replication. To elucidate SARS-CoV- 2-MP interactions we investigated transcriptomic and proteomic profiles of human monocyte-derived macrophages. While expression of the …

Faculty Versus Student Repeatability On Evaluating Translucency Of The Anterior Dentition, James L. Sheets, David B. Marx, Nina Ariani, Valentim A. R. Barão, Alvin G. Wee

Department of Statistics: Faculty Publications

The objective was to compare the repeatability between dental faculty, whose clinical practice was primarily restorative dentistry, and final year dental students in categorizing the inherent translucency of images selected at random using either a 3- or 7-point scale (translucent to opaque). Digital images of anterior dentition were randomly selected based on inherent translucency. Thirty images (five were repeated) were randomized and categorized by 20 dental students and 20 faculty on their inherent translucency. Statistical analysis was performed using an F test for analysis of variance at 95% confidence interval. A covariance parameter estimate (CPE) was accomplished to compare the …

Association Between Aqueous Atrazine And Pediatric Cancer In Nebraska, Jagadeesh Puvvula, Shannon L. Bartelt-Hunt, Balkiss S. Ouattara, Alan S. Kolok, Jesse E. Bell, Eleanor G. Rogan

Department of Civil and Environmental Engineering: Faculty Publications

Agrichemicals, chemicals used to maximize crop and animal production, can lead to water quality concerns when these chemicals run off into surface and groundwater after precipitation events. In Nebraska, one such chemical is atrazine, a suspected carcinogen. This study evaluated the association between atrazine in surface and groundwater, in relation to the incidence of pediatric cancer in Nebraska watersheds over 30 years (1 January 1987 to 31 December 2016). The watersheds were grouped into four categories based on the average atrazine concentration over the study period, using quantile classification. The associations between atrazine (ground/surface) and pediatric cancer after adjusting for …

Relationship Of Molecular Breeding Value For Beef Tenderness With Heifer Traits Through Weaning Of Their First Calf, Robert A. Cushman, Gary L. Bennett, Richard G. Tait, Anthony K. Mcneel, Eduardo Casas, Timothy P.L. Smith, Harvey C. Freetly

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

Polymorphisms in μ-calpain (CAPN1) that beneficially associate with beef tenderness are reported to antagonistically associate with calving day in beef heifers and post-partum interval to estrus in beef cows. We, therefore, hypothesized that a molecular breeding value for slice shear force, calculated based on CAPN1 and calpastatin (CAST) genotypes, would demonstrate an antagonistic relationship between genomically predicted slice shear force and ordinal calving date in replacement beef heifers. A secondary objective of this study was to evaluate the association of a polymorphism in diacylglycerol O-acyltransferase (DGAT1) with reproductive traits in beef heifers. One hundred eighty-seven MARC III heifers (¼ Angus, …

Advocacy Opportunities From Academic- Community Partnerships: Three Examples From Trans Collaborations, Debra A. Hope, Nathan Woodruff, Richard Mocarski

Trans Collaborations Academic Papers

For a number of years, much of what we know about marginalized communities from psychological research, even most social science work, came from the perspective of “research on” a particular marginalized group, with the majority group as the “healthy” reference sample (Awad et al., 2016). In part, this occurred because very few researchers are themselves members of these communities. In addition, researchers would come into a community, collect their data, and leave, with little ongoing benefit to the community itself. Over time, this exploitation led to communities becoming more suspicious of researchers (e.g., Christopher et al., 2008). Recognizing the problem, …

Validation Of High-Resolution Melting Assays For The Detection Of Virulent Strains Of Escherichia Coli O26 And O111 In Beef And Pork Enrichment Broths, Frank J. Velez, Joseph M. Bosilevac, Prashant Singh

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

Extensive validation of diagnostic assays using widely collected surveillance samples is critical for developing pathogen detection assays. The detection of potentially virulent E. coli strains is critical to the red meat industry. We previously developed two high-resolution melting (HRM) assays for detecting potentially virulent and avirulent E. coli O26 and O111 strains. Assays were validated using enriched beef (n = 36) and pork (n = 36) samples collected as part of a U.S. federal regulatory surveillance program. Data from this study showed more than 90% sensitivity and specificity for both the HRM assays, demonstrating suitability for the red meat industry …
