Inflammatory bowel diseases (IBD) are likely driven by aberrant immune responses directed against the resident microbiota. Although IBD is commonly associated with a dysbiotic microbiota enriched in putative pathobionts, the etiological agents of IBD remain unknown. Using a pathobiont-induced intestinal inflammation model and a defined bacterial community, we provide new insights into the immune-microbiota interactions during disease. In this model system, the pathobiont Helicobacter bilis instigates disease following sub-pathological dextran sulfate sodium treatment. We show that H. bilis causes mild inflammation in mono-associated mice, but severe disease in the presence of a microbiota, demonstrating synergy between the pathobiont and microbiota …

Impacts Of Active School Design On Schooltime Sedentary Behavior And Physical Activity: A Pilot Natural Experiment, Jeri Brittin, Leah Frerichs, John R. Sirard, Nancy M. Wells, Beth M. Myers, Jeanette Garcia, Dina Sorensen, Matthew J. Trowbridge, Terry Huang

Interior Design Program: Faculty Scholarly and Creative Activity

Background Children spend a significant portion of their days in sedentary behavior (SB) and on average fail to engage in adequate physical activity (PA). The school built environment may influence SB and PA, but research is limited. This natural experiment evaluated whether an elementary school designed to promote movement impacted students' school-time SB and PA.

Methods Accelerometers measured SB and PA at pre and post time-points in an intervention group who moved to the new school (n = 21) and in a comparison group experiencing no school environmental change (n = 20). Difference-in-difference (DD) analysis examined SB and PA outcomes …

The Pul37 Tegument Protein Guides Alphaherpesvirus Retrograde Axonal Transport To Promote Neuroinvasion, Alexsia L. Richards, Patricia J. Sollars, Jared D. Pitts, Austin M. Stults, Ekaterina E. Heldwein, Gary E. Pickard, Gregory A. Smith

School of Veterinary and Biomedical Sciences: Faculty Publications

A hallmark property of the neurotropic alpha-herpesvirinae is the dissemination of infection to sensory and autonomic ganglia of the peripheral nervous system following an initial exposure at mucosal surfaces. The peripheral ganglia serve as the latent virus reservoir and the source of recurrent infections such as cold sores (herpes simplex virus type I) and shingles (varicella zoster virus). However, the means by which these viruses routinely invade the nervous system is not fully understood. We report that an internal virion component, the pUL37 tegument protein, has a surface region that is an essential neuroinvasion effector. Mutation of this region rendered …

Zika Virus Encoding Nonglycosylated Envelope Protein Is Attenuated And Defective In Neuroinvasion, Arun Saravanakumar Annamalai, Aryamav Pattnaik, Bikash R.

School of Veterinary and Biomedical Sciences: Faculty Publications

ABSTRACT Zika virus (ZIKV), a mosquito-transmitted flavivirus responsible for sporadic outbreaks of mild and febrile illness in Africa and Asia, reemerged in the last decade causing serious human diseases, including microcephaly, congenital malformations, and Guillain-Barré syndrome. Although genomic and phylogenetic analyses suggest that genetic evolution may have led to the enhanced virulence of ZIKV, experimental evidence supporting the role of specific genetic changes in virulence is currently lacking. One sequence motif, VNDT, containing an N-linked glycosylation site in the envelope (E) protein, is polymorphic; it is absent in many of the African isolates but present in all isolates from the …

Effects Of Vagotomy And Fenugreek On Hyperlipidemia And Insulin Resistance, Rituraj Khound

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Hyperlipidemia is the impairment of lipid metabolism marked by abnormally high levels of lipid in circulation. This has been implicated in a number of metabolic diseases including diabetes, cardiovascular diseases, and nonalcoholic fatty liver disease. Insulin resistance is the impairment of insulin action, which leads to several diseases such as obesity and type 2 diabetes. New clinical and therapeutic approaches are warranted for the prevention and treatment of hyperlipidemia and insulin resistance. In our study, we investigated the mechanism underlying the effect of complete disruption of the sub-diaphragmatic vagus nerve (vagotomy) on hyperlipidemia and insulin sensitivity. We observed that vagotomy …

Whole Grain Processing And Effects On Carbohydrate Digestion And Fermentation, Sandrayee Brahma

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Whole grains are a major source of dietary fibers in the human diet that provide specific nutrients to the gut microbiota and thereby plays a major role in modulating microbiota composition and increasing diversity of the gut ecosystem. A common approach of consuming whole grains is in the form of ready-to-eat extruded breakfast cereals. Studies reported herein established that extrusion conditions not only affected the physicochemical properties but also in vitro starch digestibility, β-glucan extractability and in vitro fermentation characteristics of whole grain oats. Moderate screw speed (300 rpm) led to higher slowly digestible starch (SDS) with an accompanying decrease …

Development Of A Broadly Protective Modified-Live Virus Vaccine Candidate Against Porcine Reproductive And Respiratory Syndrome Virus, Haiyan Sun, Aspen Workman, Fernando A. Osorio, David J. Steffen, Hiep L.X. Vu

Nebraska Center for Virology: Faculty Publications

Modified-live virus (MLV) vaccines are widely used to protect pigs against porcine reproductive and respiratory syndrome virus (PRRSV). However, current MLV vaccines do not confer adequate levels of heterologous protection, presumably due to the substantial genetic diversity of PRRSV isolates circulating in the field. To overcome this genetic variation challenge, we recently generated a synthetic PRRSV strain containing a consensus genomic sequence of PRRSV-2. We demonstrated that our synthetic PRRSV strain confers unprecedented levels of heterologous protection. However, the synthetic PRRSV strain at passage 1 (hereafter designated CON-P1) is highly virulent and therefore, is not suitable to be used as …

Preliminary Evidence For The Impact Of Combat Experiences On Gray Matter Volume Of The Posterior Insula, Ashley N. Clausen, Sandra A. Billinger, Jason-Flor V. Sisante, Hideo Suzuki, Robin L. Aupperle

Department of Educational Psychology: Faculty Publications

Background: Combat-exposed veteran populations are at an increased risk for developing cardiovascular disease. The anterior cingulate cortex (ACC) and insula have been implicated in both autonomic arousal to emotional stressors and homeostatic processes, which may contribute to cardiovascular dysfunction in combat veteran populations. The aim of the present study was to explore the intersecting relationships of combat experiences, rostral ACC and posterior insula volume, and cardiovascular health in a sample of combat veterans.

Method: Twenty-four male combat veterans completed clinical assessment of combat experiences and posttraumatic stress symptoms. Subjects completed a magnetic resonance imaging scan and autosegmentation using FreeSurfer was …

Efficacy Of An Adenoviral Vectored Multivalent Centralized Influenza Vaccine, Amy Lingel, Brianna L. Bullard, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Mice were immunized with Adenovirus expressing the H1-con, H2-con, H3-con and H5-con HA consensus genes in combination (multivalent) and compared to mice immunized with the traditional 2010–2011 FluZone and FluMist seasonal vaccines. Immunized mice were challenged with 10–100 MLD50 of H1N1, H3N1, H3N2 and H5N1 influenza viruses. The traditional vaccines induced robust levels of HA inhibition (HI) titers, but failed to protect against five different heterologous lethal influenza challenges. Conversely, the multivalent consensus vaccine (1 × 1010 virus particles (vp)/mouse) induced protective HI titers of ≥40 against 8 of 10 influenza viruses that represent a wide degree of divergence within …

Conclusion

By many different measures, rural Nebraskans are positive about their community. Many rural Nebraskans rate their community favorably on its social dimensions: as friendly, trusting and supportive. Most rural Nebraskans say it would be difficult to leave their community and have a positive attachment to their community. And, most rural Nebraskans disagree that their community is powerless to control its future.

Across all years of this study, rural Nebraskans’ views about the change in their community have generally been positive. The proportion believing their community has changed for the better during the past year has usually been greater than …

Effectiveness Of Composting As A Biosecure Disposal Method For Porcine Epidemic Diarrhea Virus (Pedv)-Infected Pig Carcasses, Sarah Vitosh-Sillman, John Dustin Loy, Bruce Brodersen, Clayton Kelling, Kent M. Eskridge, Amy Millmier Schmidt

School of Veterinary and Biomedical Sciences: Faculty Publications

Porcine epidemic diarrhea virus (PEDV) is an enteric disease of swine that has emerged as a worldwide threat to swine herd health and production. Substantial research has been conducted to assess viability of the virus on surfaces of vehicles and equipment, in feed and water, and on production building surfaces, but little is known about the persistence in PEDV-infected carcasses and effective disposal methods thereof. This study was conducted to quantify the persistence of PEDV RNA via quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) at various time-temperature combinations and in infected piglet carcasses subjected to composting. Although this method …

Spitzer, Terry L. Sharp, Kooresh I. Shoghi, Genevieve C. Sparagna, Eva A. Rog-Zielinska, Peter Kohl, Oleh Khalimonchuk, Jean E. Schaffer, E. Dale Abel

Department of Biochemistry: Faculty Publications

Rationale: Cardiac lipotoxicity, characterized by increased uptake, oxidation and accumulation of lipid intermediates, contributes to cardiac dysfunction in obesity and diabetes. However, mechanisms linking lipid overload and mitochondrial dysfunction are incompletely understood.

Objective: To elucidate the mechanisms for mitochondrial adaptations to lipid overload in postnatal hearts in vivo.

Methods and Results: Using a transgenic mouse model of cardiac lipotoxicity overexpressing long-chain acyl-CoA synthetase 1 in cardiomyocytes, we show that modestly increased myocardial fatty acid uptake leads to mitochondrial structural remodeling with significant reduction in minimum diameter. This is associated with increased palmitoyl-carnitine oxidation and increased reactive oxygen species (ROS) generation …

Reliability And Concurrent Validity Of Select C3 Logix Test Components, Madeline Simon, Arthur C. Maerlender, Katelyn Metzger, Laura Decoster, Amy Hollingworth, Tamara Valovich Mcleod

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

We sought to investigate the one-week and within-session reliability of the instrumented balance error scoring system test and the concurrent validity/one-week reliability of two neurocognitive assessments available through C3 Logix. (n = 37) Participants completed two balance error scoring system tests separated by the Trails A, Trails B, and Symbol Digit Modality test available through C3 Logix, and with paper and pencil. We found that the instrumented balance error scoring system test demonstrated strong one-week reliability and that neuropsychological tests available through C3 Logix show acceptable concurrent validity with standard (comparable) paper and pencil measures.

Responding To Infertility: Lessons From A Growing Body Of Research And Suggested Guidelines For Practice, Karina M. Shreffler, Arthur L. Greil, Julia Mcquillan

Department of Sociology: Faculty Publications

Infertility is a common, yet often misunderstood, experience. Infertility is an important topic for family scientists because of its effects on families; its relevance to research in related areas, such as fertility trends and reproductive health; and its implications for practitioners who work with individuals and couples experiencing infertility. In this review, we focus on common misperceptions in knowledge and treatment of infertility and highlight insights from recent research that includes men, couples, and people with infertility who are not in treatment. The meaning of parenthood, childlessness, awareness of a fertility problem, and access to resources are particularly relevant for …

Examining The Relationship Between Home Literacy Environment And Neural Correlates Of Phonological Processing In Beginning Readers With And Without A Familial Risk For Dyslexia: An Fmri Study, Sara J. Powers, Yingying Wang, Sara D. Beach, Georgios D. Sideridis, Nadine Gaab

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Developmental dyslexia is a language-based learning disability characterized by persistent difficulty in learning to read. While an understanding of genetic contributions is emerging, the ways the environment affects brain functioning in children with developmental dyslexia are poorly understood. A relationship between the home literacy environment (HLE) and neural correlates of reading has been identified in typically developing children, yet it remains unclear whether similar effects are observable in children with a genetic predisposition for dyslexia. Understanding environmental contributions is important given that we do not understand why some genetically at-risk children do not develop dyslexia. Here we investigate for the …

Brain Encoding Of Saltatory Velocity Through A Pulsed Pneumotactile Array In The Lower Face, Rebecca Custead, Hyuntaek Oh, Yingying Wang, Steven M. Barlow

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Processing dynamic tactile inputs is a primary function of the somatosensory system. Spatial velocity encoding mechanisms by the nervous system are important for skilled movement production and may play a role in recovery of sensorimotor function following neurological insult. Little is known about tactile velocity encoding in mechanosensory trigeminal networks required for speech, suck, mastication, and facial gesture.

High resolution functional magnetic resonance imaging (fMRI) was used to investigate the neural substrates of velocity encoding in the human orofacial somatosensory system during unilateral saltatory pneumotactile stimulation of perioral and buccal hairy skin in 20 neurotypical adults. A custom multichannel, scalable …

Prevalence Of Kaposi’S Sarcoma-Associated Herpesvirus In Uygur And Han Populations From The Urumqi And Kashgar Regions Of Xinjiang, China, Jun Zheng, Yang Yang, Meng Cui, Zhan-Jun Shu, Li-Li Han, Zhen-Qiu Liu, Charles Wood, Tiejun Zhang, Yan Zeng

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma-associated herpesvirus (KSHV) is the infectious etiologic agent associated with Kaposi’s sarcoma (KS), primary effusion lymphoma, and multicentric Castleman disease. It has been shown that high KSHV prevalence and high incidence of both classic KS and AIDSassociated KS are found mostly among people of Uygur ethnicity in Xinjiang, while people of Han ethnicity in Xinjiang have a higher KSHV seroprevalence than those of other Han populations in mainland China. However, it is still unclear why there is such geographical and population variation in KSHV distribution in China. In this work, we focused on the populations in the Kashgar region …

The Interaction Of Temporal And Spectral Acoustic Information With Word Predictability On Speech Intelligibility, Bahar Somayeh Shahsavarani

Department of Communication Studies: Dissertations, Theses, and Student Research

High-level, top-down information such as linguistic knowledge is a salient cortical resource that influences speech perception under most listening conditions. But, are all listeners able to exploit these resources for speech facilitation to the same extent? It was found that children with cochlear implants showed different patterns of benefit from contextual information in speech perception compared with their normal-haring peers. Previous studies have discussed the role of non-acoustic factors such as linguistic and cognitive capabilities to account for this discrepancy. Given the fact that the amount of acoustic information encoded and processed by auditory nerves of listeners with cochlear implants …

Cross-Reactive Immunity To Porcine Reproductive And Respiratory Syndrome Virus And Its Contribution To Protection, Ignacio Correas

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Due to the vast geographical distribution and significant economic losses generated, porcine reproductive and respiratory syndrome virus (PRRSV) can be considered the most important swine pathogen of contemporary times. Current control and eradication strategies against PRRSV have difficulty succeeding because of their complex nature and the absence of an effective vaccine. A major obstacle for PRRSV vaccine development is the broad heterogeneity of the virus, both at the genetic and antigenic level, its rapid evolution, and an incomplete knowledge of the immune responses responsible for clearing the virus from the host. Specifically, how known correlates of protection against PRRSV—neutralizing antibodies …

Swallowing Mechanics Associated With Artificial Airways, Bolus Properties, And Penetration–Aspiration Status In Trauma Patients, Angela M. Dietsch, Christopher B. Rowley, Nancy Pearl Solomon, William G. Pearson Jr.

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: Artificial airway procedures such as intubation and tracheotomy are common in the treatment of traumatic injuries, and bolus modifications may be implemented to help manage swallowing disorders. This study assessed artificial airway status, bolus properties (volume and viscosity), and the occurrence of laryngeal penetration and/or aspiration in relation to mechanical features of swallowing.

Method: Coordinates of anatomical landmarks were extracted at minimum and maximum hyolaryngeal excursion from 228 videofluoroscopic swallowing studies representing 69 traumatically injured U.S. military service members with dysphagia. Morphometric canonical variate and regression analyses examined associations between swallowing mechanics and bolus properties based on artificial airway …

Multiple Origins Of Endosymbionts In Chlorellaceae With No Reductive Effects On The Plastid Or Mitochondrial Genomes, Weishu Fan, Wenhu Guo, James L. Van Etten, Jeffrey P. Mower

James Van Etten Publications

Ancient endosymbiotic relationships have led to extreme genomic reduction in many bacterial and eukaryotic algal endosymbionts. Endosymbionts in more recent and/or facultative relationships can also experience genomic reduction to a lesser extent, but little is known about the effects of the endosymbiotic transition on the organellar genomes of eukaryotes. To understand how the endosymbiotic lifestyle has affected the organellar genomes of photosynthetic green algae, we generated the complete plastid genome (plastome) and mitochondrial genome (mitogenome) sequences from three green algal endosymbionts (Chlorella heliozoae, Chlorella variabilis and Micractinium conductrix). The mitogenomes and plastomes of the three newly sequenced endosymbionts …

Current Prospects Of Type Ii Interferon Γ Signaling & Autoimmunity, Daniel S. Green, Howard A. Young, Julio C. Valencia

Public Health Resources

Interferon γ (IFNγ) is a pleiotropic protein secreted by immune cells. IFNγ signals through the IFNγ receptor, a protein complex that mediates downstream signaling events. Studies into IFNγ signaling have provided insight into the general concepts of receptor signaling, receptor internalization, regulation of distinct signaling pathways, and transcriptional regulation. Although IFNγ is the central mediator of the adaptive immune response to pathogens, it has been shown to be involved in several non-infectious physiological processes. This review will provide an introduction into IFNγ signaling biology and the functional roles of IFNγ in the autoimmune response.

Rural Futures Institute: Publications

Conclusion

Rural Nebraskans purchase their food from a variety of stores. Almost four in ten buy most of their food from a supercenter (like Wal-Mart or Costco). Just over three in ten typically shop at a supermarket and just under three in ten buy most of their food at a small grocery store. Differences in the type of store most utilized occur by community size. Persons living in or near larger communities are more likely than persons living in or near smaller communities to purchase the majority of their food from either a supermarket or supercenter.

Persons living in or …

Structure-Based Design Of Hepatitis C Virus Vaccines That Elicit Neutralizing Antibody Responses To A Conserved Epitope, Brian G. Pierce, Elisabeth N. Boucher, Kurt H. Piepenbrink, Monir Ejemal, Chelsea A. Rapp, William D. Thomas Jr, Eric J. Sundberg, Zhiping Weng, Yang Wang

Food for Health: Publications

Despite recent advances in therapeutic options, hepatitis C virus (HCV) remains a severe global disease burden, and a vaccine can substantially reduce its incidence. Due to its extremely high sequence variability, HCV can readily escape the immune response; thus, an effective vaccine must target conserved, functionally important epitopes. Using the structure of a broadly neutralizing antibody in complex with a conserved linear epitope from the HCV E2 envelope glycoprotein (residues 412 to 423; epitope I), we performed structure-based design of immunogens to induce antibody responses to this epitope. This resulted in epitope-based immunogens based on a cyclic defensin protein, as …
