Genetic Variation And Possible Mechanisms Driving The Evolution Of Worldwide Fig Mosaic Virus Isolates, Jeewan Jyot Walia, Anouk Willemsen, Eminur Elci, Kadriye Caglayan, Bryce W. Falk, Luis Rubio

Nebraska Center for Virology: Faculty Publications

Fig mosaic virus (FMV) is a multipartite negative-sense RNA virus infecting fig trees worldwide. FMV is transmitted by vegetative propagation and grafting of plant materials, and by the eriophyid mite Aceria ficus. In this work, the genetic variation and evolutionary mechanisms shaping FMV populations were characterized. Nucleotide sequences from four genomic regions (each within the genomic RNAs 1, 2, 3, and 4) from FMV isolates from different countries were determined and analyzed. FMV genetic variation was low, as is seen for many other plant viruses. Phylogenetic analysis showed some geographically distant FMV isolates which clustered together, suggesting long-distance migration. …

Turnip Crinkle Virus Coat Protein Inhibits The Basal Immune Response To Virus Invasion In Arabidopsis By Binding To The Nac Transcription Factor Tip, Teresa Donze, Feng Qu, Paul Twigg, T. Jack Morris

Nebraska Center for Virology: Faculty Publications

Turnip crinkle virus (TCV) has been shown to interact with a NAC transcription factor, TIP, of Arabidopsis thaliana, via its coat protein (CP). This interaction correlates with the resistance response manifested in TCV-resistant Arabidopsis ecotype Di-17. We report that failure of a mutated CP to interact with TIP triggered the corresponding TCV mutant (R6A) to cause more severe symptoms in the TCV-susceptible ecotype Col-0. We hypothesized that TCV regulates antiviral basal immunity through TIP-CP interaction. Consistent with this hypothesis, we found that the rate of accumulation of R6A was measurably slower than wild-type TCV over the course of an …

The Law Of Native American Hunting, Fishing And Gathering Outside Of Reservation Boundaries In The United States And Canada, Guy Charlton

Canada-United States Law Journal

This article examines and compares the law of Native American/Aboriginal hunting, fishing and gathering rights in those areas which are located outside of reserved land area in Canada and the United States. The article argues that despite the differing statutory and constitutional traditions, both states' law and policy towards the Native American continues to reflect the underlying premises of the colonial project. While indigenous peoples have significant use rights, national, state and provincial power remains the primary locus of regulatory authority.

“It Is Laced With Faults”: American Indians, Public Participation And The Politics Of Siting A High-Level Nuclear Waste Repository, Jesse P. Van Gerven

Societies Without Borders

In this article I analyze American Indian claims made during the siting process for a high-level nuclear waste repository at Yucca Mountain, Nevada. By utilizing the concepts of distribution and recognition (Fraser 2003) to analyze American Indian claims for financial compensation, cultural artifact/resource protection, and environmental justice I reveal the existence and extent of both objective and intersubjective obstacles preventing greater public participation in environmental decision-making. Through a textual/discourse analysis of public documents associated with the Yucca Mountain Project, my analysis demonstrates how distributive and recognitional injustices impede democratic participation in environmental decision-making, which contributes to the continuation of environmental …

The Rise Of Human Rights Education: Opportunities, Challenges, And Future Possibilities, Lindsey N. Kingston

Societies Without Borders

Human rights education (HRE) has gained increasing support as a tool for promoting social responsibility and global respect for international human rights standards. Many schools and universities include HRE in their curricula in an attempt to foster a sense of global citizenship among students, yet educators still grapple with how to most effectively include human rights in undergraduate programs. In an attempt to provide resources and to promote effective HRE, this article examines the rise of human rights education and analyzes its potential for positive change. In particular, high impact learning practices (such as community partnerships and short-term study abroad …

If They Cut Off Both Of My Hands, I Will Write Music Anyway: Dmitri Shostakovich’S Interpretation Of The Poetic Voice In Opus 143 And Opus 146, Erich Barganier

Theses & ETDs

Dmitiri Shostakovich developed an intimate relationship with the literature that surrounded him. In his musical adaptations of Russian poetry, he reinterpreted original authorial visions for a contemporary audience, which served to satirize and critique the social conditions of the Soviet Union. “Six Poems of Marina Tsvetaeva” and “Four Poems of Captain Lebyadkin” mix musical technique and lyrical meaning to critically asses the relationship between society and the artist. Shostakovich combines the original author’s voice with his musical interpretation of the work, creating a dialogue between voices from the past and the present. The multiple levels of interpretation that manifest through …

Cultivating Blossoming And Healing Ecologies Via Radical Virtue Ethics Con Cariño: Encouraging Learning, Care And Restorative Justice, Andrea Alejandra Ortiz Sotelo

Theses & ETDs

Our boundaries and responsibilities evolve as our communities and ecologies change. We generate value (and capital) from our active and creative connections but we often fail to recognize how our collective prosperity is proportional to our capacity to care for/about each other. All of us can blossom, but we need to learn how to help each other to flourish. If we care about our lives, (which we should/must learn to do) our becoming must be resourceful and resilient. We are all vulnerable because we are living creatures, although some of us experience more environmental injustices than others. It is necessary …

Sorting Through The Muc: A Characterization Of Muc1 In Acquired Chemo-Resistance In Non-Small Cell Lung Cancer, Alexandria Wells

Theses & ETDs

Mucin 1 (MUC1) is a glycoprotein expressed on the apical surface of epithelial cells in organs such as the lung. Typically upregulated during cases of acute inflammation, an overexpression of MUC1 has been observed in cases of acquired resistance to Tumor Necrosis Factor-Related Apoptosis Inducing Ligand (TRAIL) in non-small cell lung cancer. The ability of cancer cells to gain resistance to chemotherapy treatments has been attributed to their ability to evade apoptosis initiated by ligands like TRAIL through the dysregulation of otherwise harmless proteins, such as MUC1. A decrease in catalase expression, coupled by an increase in the presence of …

El Manuscrito De 'La Casa De Asterion': Mosaico De Un Proceso De Escritura, Maria Laura Bocaz-Leiva

Modern Languages & Literatures Articles

Los materiales preredaccionales del escritor Jorge Luis Borges son escasos y de dificil acceso. Daniel Balderston, en "Los manuscritos de Borges: imaginar una realidad más compleja", comenta las múltiples dificultades que puede enfrentar el investigador que se decida a estudiar el proceso de escritura de algún texto: dispersos en diferentes depósitos, celosamente guardados por coleccionistas o particulares, ocasionalmente a la venta por sumas extravagantes, a veces sólo disponibles a través de una edición facsimilar; siguen siendo en deñnjtiva una fuente de estudio anhelada y esquiva, una "terra incognita."

Designs And Techniques That Improve The Pullout Strength Of Pedicle Screws In Osteoporotic Vertebrae: Current Status, Thomas M. Shea, Jake Laun, Sabrina A. Gonzalez-Blohm, James J. Doulgeris, William E. Lee, Kamran Aghayev, Frank D. Vrionis

Chemical, Biological and Materials Engineering Faculty Publications

Osteoporosis is a medical condition affecting men and women of different age groups and populations. The compromised bone quality caused by this disease represents an important challenge when a surgical procedure (e.g., spinal fusion) is needed after failure of conservative treatments. Different pedicle screw designs and instrumentation techniques have been explored to enhance spinal device fixation in bone of compromised quality. These include alterations of screw thread design, optimization of pilot hole size for non-self-tapping screws, modification of the implant’s trajectory, and bone cement augmentation. While the true benefits and limitations of any procedure may not be realized until they …

Diet Of The Antillean Manatee (Trichechus Manatus Manatus) In Belize, Central America, Aarin Conrad Allen

HCNSO Student Theses and Dissertations

Belize has been identified as an important location for Antillean manatees (Trichechus manatus manatus), harboring the highest known population density of this subspecies. Information about their dietary habit is important in determining habitat requirements and aiding in conservation efforts. The main objective of this study was to identify the key plant species consumed by manatees in Belize and to establish differences in diet based on location, sex, size classification, and season. Samples were collected from two different locations within Belize where manatees are known to aggregate: Southern Lagoon and the Drowned Cayes off of Belize City. The contents …

Time To Competitive Exclusion, Andrew M. Kramer, John M. Drake

Integrative Biology Faculty and Staff Publications

A predictive theory of population extinction for natural populations requires integrating the effects of stochasticity with the interactions engaged in with populations of other species. The theory of competitive exclusion predicts that inferior competitors for a limiting resource will be driven to extinction, but the effects of resource competition on time to extinction have not been examined. We studied a stochastic version of Tilman's resource competition model to examine two species competition-driven extinction. Simulations showed that competitive imbalance, population size and demographic rates of the “inferior” competitor were the most important determinants of mean extinction time, while factors including resource …

Sharing, Subsistence, And Social Norms In Northern Siberia, John Ziker

Anthropology Faculty Publications and Presentations

The majority of families in Ust’-Avam in northern Siberia are dependent on subsistence hunting, fishing, and trapping and have been part of a vertically integrated industrial economy in a remote area of the former Soviet Union. Thus, the results from behavioral games conducted there in 2003—the dictator game (DG), the ultimatum game (UG), and the third-party punishment game (TPG)—lend themselves to comparison with other indigenous hunter-gatherers, as well as with working communities in other nation-states.

The Prevalence Of Antibodies Against Wheat And Milk Proteins In Blood Donors And Their Contribution To Neuroimmune Reactivities, Aristo Vojdani, Datis Kharrazian, Partha Sarathi Mukherjee

Mathematics Faculty Publications and Presentations

The aim of this study was to look for the presence of IgG, IgM, and IgA antibodies against two widely consumed foods, wheat and milk, in a relatively large number of specimens. As wheat, milk, and their antigens have been found to be involved in neuroimmune disorders, we measured the co-occurrence of their antibodies against various neural antigens. We assessed the reactivity of sera from 400 donors to wheat and milk proteins, GAD-65, cerebellar, MBP, and MOG. Statistical analysis showed significant clustering when certain wheat and milk protein antibodies were cross-referenced with neural antibodies. Approximately half of the sera with …

The “Female Fertility–Social Stratification–Hypergyny” Hypothesis Of Male Homosexual Preference: Factual, Conceptual And Methodological Errors In Barthes Et Al. [Commentary], Doug P. Vanderlaan, Zachary H. Garfield, Melissa J. Garfield, Jean-Baptiste Leca, Paul L. Vasey, Raymond B. Hames

Department of Anthropology: Faculty Publications

Barthes, Godelle, and Raymond (2013, Evolution and Human Behavior, 34, 155–163) proposed a hypothesis to (1) identify the process by which genes influencing male homosexual preference (MHP) are passed on over evolutionary time, and (2) account for why life-course persistent MHP is restricted to humans. According to their hypothesis, certain genes lower reproductive success in male carriers by causing MHP, but these same genes promote fertility in female carriers (i.e., sexual antagonism). Barthes et al. proposed that the female carriers of genes for MHP have physical cues of fertility (i.e., beauty) that help them marry up the social class …

High-Sulfur In Beef Cattle Diets: A Review, M. E. Drewnoski, D. J. Pogge, S. L. Hansen

Department of Animal Science: Faculty Publications

While many cattle feeding areas in the United States have long dealt with high sulfate water, increased feeding of ethanol co-products such as distillers grains with solubles to beef cattle has led to a corresponding increase in dietary sulfur. As a result, sulfur metabolism in the ruminant has been the focus of many research studies over the past ten years, and advances in our knowledge have been made. Excessive sulfur in cattle diets may have implications on trace mineral absorption, dry matter intake, and overall cattle growth. This review will focus on what we have learned about the metabolism of …

Neibergs, E. John Pollak, Robert D. Schnabel, Christopher M. Seabury, Daniel W. Shike, W. M. Snelling, Matthew L. Spangler, Robert L. Weaber, D. J. Garrick, Jeremy F. Taylor

Department of Animal Science: Faculty Publications

Background: The identification of genetic markers associated with complex traits that are expensive to record such as feed intake or feed efficiency would allow these traits to be included in selection programs. To identify large-effect QTL, we performed a series of genome-wide association studies and functional analyses using 50 K and 770 K SNP genotypes scored in 5,133 animals from 4 independent beef cattle populations (Cycle VII, Angus, Hereford and Simmental × Angus) with phenotypes for average daily gain, dry matter intake, metabolic mid-test body weight and residual feed intake.

Results: A total of 5, 6, 11 and 10 significant …

Background: Porcine circovirus 2 is the primary agent responsible for inducing a group of associated diseases known as Porcine Circovirus Associated Diseases (PCVAD), which can have detrimental effects on production efficiency as well as causing significant mortality. The objective of this study was to evaluate variation in viral replication, immune response and growth across pigs (n = 974) from different crossbred lines. The approach used in this study was experimental infection with a PCV2b strain of pigs at an average of 43 days of age.

Results: The sequence of the PCV2b isolate used in the challenge was similar with a …

Quantitative Trait Loci For Energy Balance Traits In An Advanced Intercross Line Derived From Mice Divergently Selected For Heat Loss, Larry J. Leamy, Kari Elo, Merlyn K. Nielsen, Stephanie R. Thorn, William Valdar, Daniel Pomp

Department of Animal Science: Faculty Publications

Obesity in human populations, currently a serious health concern, is considered to be the consequence of an energy imbalance in which more energy in calories is consumed than is expended. We used interval mapping techniques to investigate the genetic basis of a number of energy balance traits in an F₁₁ advanced intercross population of mice created from an original intercross of lines selected for increased and decreased heat loss. We uncovered a total of 137 quantitative trait loci (QTLs) for these traits at 41 unique sites on 18 of the 20 chromosomes in the mouse genome, with X-linked QTLs …

Effects Of Grazing On Nebraska Sandhills Meadow Forage Nutrient Content, Jared V. Judy, Jacki A. Musgrave, L. Aaron Stalker Stalker, Karla H. Jenkins, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Nebraska Sandhills subirrigated meadow pastures were utilized to measure the effects of grazing on forage nutrient content in summer pastures. Pre-grazed pastures had greater protein and in vitro dry matter digestibility levelsand lower neutral detergent fiber levels compared with post-grazed pastures early in the grazing season. By late July, post-grazed vs. pre-grazed pastures did not differ in in vitro dry matter digestibility and neutral detergent fiber levels. Observed results indicate the greatest differences in nutrient content between post-grazed and pre-grazed pastures occur early in the grazing season.
