Understanding Religious Tolerance In Yongchang, China, Liming Gao

Honors Program: Senior Projects (Public)

The formation of China is a process of national integration and a fusion of different beliefs. However, under Chairman Mao (1949-1976) and specifically during the Cultural Revolution (1966-1976), people were reeducated to focus on Communism and expel remnants of traditional Chinese culture including the various religions. Although, after the Cultural Revolution, China reinstated its policy of religious freedom, there were still strict laws against religion. Despite such circumstances, Chinese people still practice their religious beliefs. The Yongchang area, located in Gansu Province in the northwest of China is a typical region of Chinese culture. At the same time, compared to …

Methods: We used data from the 2017-18 Bangladesh Demographic and Health (BDHS) Survey. Logistic regression technique was used to investigate how toilet sharing practices, water source locations, and different sociodemographic factors were associated with observed handwashing places without soap. Results: …

Social Media, Populism, And Covid-19: Weibo Users’ Reactions To Anti-Chinese Discourse, Theresa Catalano, Peiwen Wang

Department of Teaching, Learning, and Teacher Education: Faculty Publications

US government communication about the COVID-19 pandemic, particularly the ‘Chinese virus’ discourse adopted by Donald Trump and his administration, has led to real-world violence and triggered heated discussions across social media sites, including Sina Weibo (aka Chinese Twitter). The current study explores the relationship between populism and social media by examining how Sina Weibo users respond to Trump’s communication on the virus. Employing multimodal critical discourse analysis, we examine both visual and verbal strategies used to build counter-discourses that challenge the use of terms such as ‘Chinese virus’. Findings demonstrate the potential of Weibo as a platform of resistance and …

Micrornas As Biomarkers For Early Diagnosis, Prognosis, And Therapeutic Targeting Of Ovarian Cancer, Yegane Mirahmadi, Reza Nabavi, Fourough Taheri, Mohammad Mahdi Samadian, Zari Naderi Ghale-Noie, Mahsa Farjami, Abbas Samadi-Khouzani, Meysam Yousefi, Sara Azhdari, Arash Salmaninejad, Amirhossein Sahebkar

Department of Animal Science: Faculty Publications

Ovarian cancer is the major cause of gynecologic cancer-related mortality. Regardless of outstanding advances, which have been made for improving the prognosis, diagnosis, and treatment of ovarian cancer, the majority of the patients will die of the disease. Late-stage diagnosis and the occurrence of recurrent cancer after treatment are the most important causes of the high mortality rate observed in ovarian cancer patients. Unraveling the molecular mechanisms involved in the pathogenesis of ovarian cancer may help find new biomarkers and therapeutic targets for ovarian cancer. MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression, mostly at the posttranscriptional stage, …

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, …

Natterer In Neotropical Nematoda: Species Described By Rudolphi, Diesing, And Molin, Ricardo Guerrero

MANTER: Journal of Parasite Biodiversity

Between 1817 and 1835 Johann Natterer collected 1,729 samples of endoparasitic helminths in Brazil and southern Venezuela. Of the 323 names that were assigned to the collected nematode specimens, 163 are still valid and accepted species, 84 are still doubtful, and 76 must be rejected. In this work, each name is analyzed and correlated to the literature to clarify its taxonomic status.

The purpose of this review of the material collected by Natterer is to establish a complete list of all described species; their current status; and whether they are valid species, synonyms, or nomen nudum as well as to …

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 …

Importance Of Woodland Patches As Hibernacula For Gartersnakes In A Prairie River Floodplain Of Central Nebraska, Tony Bridger, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Gartersnakes are common inhabitants along prairie rivers in the Great Plains, but little information is known about hibernacula among diverse floodplain habitats. We radio-tracked Common Gartersnakes (Thamnophis sirtalis) and Plains Gartersnakes (Thamnophis radix) to hibernacula on islands in a braided river system subject to frequent environmental changes along the Platte River in central Nebraska. We further examined capture rates of gartersnakes in floodplain woodland patches from June to November to examine seasonal use of this habitat. In early and mid-September, movements of snakes with transmitters were in grasslands. From late September to mid-October, the farthest movements …

Transcriptomics Reveals The Putative Mycoparasitic Strategy Of The Mushroom Entoloma Abortivum On Species Of The Mushroom Genus Armillaria, Rachel A. Koch, Joshua Herr

Department of Plant Pathology: Faculty Publications

During mycoparasitism, a fungus—the host—is parasitized by another fungus—the mycoparasite. The genetic underpinnings of these relationships have been best characterized in ascomycete fungi. However, within basidiomycete fungi, there are rare instances of mushroom-forming species parasitizing the reproductive structures, or sporocarps, of other mushroom-forming species, which have been rarely investigated on a genetic level. One of the most enigmatic of these occurs between Entoloma abortivum and species of Armillaria, where hyphae of E. abortivum are hypothesized to disrupt the development of Armillaria sporocarps, resulting in the formation of carpophoroids. However, it remains unknown whether carpophoroids are the direct result of a …

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 …

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 …

These tetrabothriids are characterized, among 44 species of Tetrabothrius in avian hosts, by attributes of the scolex, male and female organ systems, structure and dimensions of the vitelline gland, numbers of testes, configuration of the genital atrium, genital papillae and the male and female atrial …

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. …

A Dedicated Flavin-Dependent Monooxygenase Catalyzes The Hydroxylation Of Demethoxyubiquinone Into Ubiquinone (Coenzyme Q) In Arabidopsis, Scott Latimer, Shea A. Keene, Lauren R. Stutts, Antoine Berger, Ann C. Bernert, Eric Soubeyrand, Janet D. Wright, Catherine F. Clarke, Anna K. Block, Thomas A. Colquhoun, Christian Elowsky, Alan C. Christensen, Mark A. Wilson, Gilles J. Basset

Department of Biochemistry: Faculty Publications

Ubiquinone (Coenzyme Q) is a vital respiratory cofactor and liposoluble antioxidant. In plants, it is not known how the C-6 hydroxylation of demethoxyubiquinone, the penultimate step in ubiquinone biosynthesis, is catalyzed. The combination of cross-species gene network modeling along with mining of embryo-defective mutant databases of Arabidopsis thaliana identified the embryo lethal locus EMB2421 (At1g24340) as a top candidate for the missing plant demethoxyubiquinone hydroxylase. In marked contrast with prototypical eukaryotic demethoxyubiquinone hydroxylases, the catalytic mechanism of which depends on a carboxylatebridged di-iron domain, At1g24340 is homologous to FADdependent oxidoreductases that instead use NAD(P)H as an electron donor. …

Evolving Protein Demand And Income Elasticity, Timothy Meyer

Cornhusker Economics

Teaching large classes in the Ag Econ department has some unique benefits. One of them is that I have a pulse on the attitudes of a large cross-section of producers. One concern that has been gradually gaining momentum is the threat that plant protein poses against traditional animal protein, namely beef.

Trends in protein demand do not support this specific fear. In general, consumers’ appetite for animal protein continues to grow. This article explains the concept of income elasticity, along with the changing income elasticities of specific meats.

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, …

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 …
