Identification Of Simplified Microbial Communities That Inhibit Clostridioides Difficile Infection Through Dilution/Extinction, Jennifer M. Auchtung, Eva C. Preisner, James Collins, Armando I. Lerma, Robert A. Britton

Department of Food Science and Technology: Faculty Publications

The gastrointestinal microbiome plays an important role in limiting susceptibility to infection with Clostridioides difficile. To better understand the ecology of bacteria important for C. difficile colonization resistance, we developed an experimental platform to simplify complex communities of fecal bacteria through dilution and rapidly screen for their ability to resist C. difficile colonization after challenge, as measured by 􏰀100-fold reduction in levels of C. difficile in challenged communities. We screened 76 simplified communities diluted from cultures of six fecal donors and identified 24 simplified communities that inhibited C. difficile colonization in vitro. Sequencing revealed that simplified communities were composed of …

Fecal Short-Chain Fatty Acid Concentrations Increase In Newly Paired Male Marmosets (Callithrix Jacchus), Lifeng Zhu, Mallory J. Suhr Van Haute, Haley R. Hassenstab, Caroline Smith, Devin J. Rose, Aaryn C. Must, Andrew K. Benson, Jeffrey A. French

Department of Food Science and Technology: Faculty Publications

The role by which the gut microbiome influences host health (e.g., energy equilibrium and immune system) may be partly mediated by short-chain fatty acids, which are bacterial fermentation products from the dietary fibers. However, little is known about longitudinal changes in gut microbiome metabolites during cohabitation alongside social contact. In common marmosets (Callithrix jacchus), the gut microbiome community is influenced by social contact, as newly paired males and females develop convergent microbial profiles. Here, we monitored the dynamics of short-chain fatty acid concentrations in common marmoset feces from the prepairing (PRE) to postpairing (POST) stages. In males, we observed that …

Acrfinder: Genome Mining Anti-Crispr Operons In Prokaryotes And Their Viruses, Haidong Yi, Le Huang, Bowen Yang, Javi Gomez, Han Zhang, Yanbin Yin

Department of Food Science and Technology: Faculty Publications

Anti-CRISPR (Acr) proteins encoded by (pro)phages/(pro)viruses have a great potential to enable a more controllable genome editing. However, genome mining new Acr proteins is challenging due to the lack of a conserved functional domain and the low sequence similarity among experimentally char- acterized Acr proteins. We introduce here AcrFinder, a web server (http://bcb.unl.edu/AcrFinder) that combines three well-accepted ideas used by pre- vious experimental studies to pre-screen genomic data for Acr candidates. These ideas include ho- mology search, guilt-by-association (GBA), and CRISPR-Cas self-targeting spacers. Compared to existing bioinformatics tools, AcrFinder has the following unique functions: (i) it is the first online …

Wild Primate Microbiomes Prevent Weight Gain In Germ-Free Mice, Dimitrios N. Sidiropoulos, Gabriel A. Al-Ghalith, Robin R. Shields-Cutler, Tonya L. Ward, Abigail J. Johnson, Pajau Vangay, Dan Knights, Purna C. Kashyap, Yibo Xian, Amanda E. Ramer-Tait, Jonathan B. Clayton

Department of Food Science and Technology: Faculty Publications

Background: The gut microbiome harbors trillions of bacteria that play a major role in dietary nutrient extraction and host metabolism. Metabolic diseases such as obesity and diabetes are associated with shifts in microbiome composition and have been on the rise in Westernized or highly industrialized countries. At the same time, Westernized diets low in dietary fiber have been shown to cause loss of gut microbial diversity. However, the link between microbiome composition, loss of dietary fiber, and obesity has not been well defined.

Results: To study the interactions between gut microbiota, dietary fiber, and weight gain, we transplanted captive and …

The International Scientific Association For Probiotics And Prebiotics (Isapp) Consensus Statement On The Definition And Scope Of Synbiotics, Kelly S. Swanson, Glenn R. Gibson, Robert W. Hutkins, Raylene A. Reimer, Gregor Reid, Kristin Verbeke, Karen P. Scott, Hannah D. Holscher, Meghan B. Azad, Nathalie M. Delzenne, Mary Ellen Sanders

Department of Food Science and Technology: Faculty Publications

In May 2019, the International Scientific Association for Probiotics and Prebiotics (ISAPP) convened a panel of nutritionists, physiologists and microbiologists to review the definition and scope of synbiotics. The panel updated the definition of a synbiotic to “a mixture comprising live microorganisms and substrate(s) selectively utilized by host microorganisms that confers a health benefit on the host”. The panel concluded that defining synbiotics as simply a mixture of probiotics and prebiotics could suppress the innovation of synbiotics that are designed to function cooperatively. Requiring that each component must meet the evidence and dose requirements for probiotics and prebiotics individually could …

Benson, Tom Elmo Clemente, Amanda E. Ramer-Tait

Department of Food Science and Technology: Faculty Publications

Scope: Previous studies have suggested that diets rich in omega-3 and low in omega-6 long- longchain polyunsaturated fatty acids (PUFAs) can limit the development of metabolic syndrome (MetS). Transgenic soybeans yielding oils enriched for omega-3 PUFAs represent a new and readily-available option for incorporating omega-3 PUFAs into diets to provide health benefits. Methods and Results: Transgenic soybean oils, enriched for either stearidonic acid (SDA) or eicosapentaenoic acid (EPA), are incorporated into diets to test their effects on limiting the development of MetS in a mouse model of diet-induced obesity. Supplementation with SDA- but not EPA-enriched oils improved features …

Polyphenolic Fractions Isolated From Red Raspberry Whole Fruit, Pulp, And Seed Differentially Alter The Gut Microbiota Of Mice With Diet-Induced Obesity, Yibo Xian, Rong Fan, Jing Shao, Ashley Mulcahy Toney, Soonkyu Chung, Amanda E. Ramer-Tait

Department of Food Science and Technology: Faculty Publications

Polyphenol extracts from red raspberry (RR) whole fruit or pulp, but not seed, attenuate high-fat (HF) dietinduced obesity in mice. Because host metabolism is linked to the microbiota, we investigated the effects of polyphenols from RR fruit, pulp, and seed on the microbiome. RR polyphenols significantly decreased the abundance of specific taxa that were increased during HF feeding relative to a low-fat diet, including Ruminococcus and an unclassified genus from Clostridiales. Compared to a HF diet, pulp and seed polyphenols increased Roseburia abundance and decreased levels of an unclassified genus from Mogibacteriaceae. RR seed polyphenols uniquely increased Bifidobacterium compared …

Targeting Homologous Recombination Addicted Tumors: Challenges And Opportunities, Talia Golan, Jonathan Brody, Md

Kimmel Cancer Center Faculty Papers

Recent advances in next generation sequencing (NGS) and molecular subtyping of tumors have opened the door to clinically available targeted therapies. Although the treatment of many solid tumors still rely on a steady regimen of non-targeted chemotherapeutic agents, it is becoming increasingly more apparent that certain tumors with defects in DNA damage repair (DDR) genes may be exquisitely sensitive to DNA damaging agents or therapies targeting key elements of this pathway such PARP1, ATR, or ATM. Still, for tumors with DDR defects the challenges are multi-fold including: (I) identifying these tumors in patients in time for a window of opportunity …

Mothers’ And Fathers’ Self-Regulation Capacity, Dysfunctional Attributions And Hostile Parenting During Early Adolescence: A Process-Oriented Approach, Melissa L. Sturge-Apple, Zhi Li, Meredith Martin, Hannah R. Jones-Gordils, Patrick T. Davies

Department of Educational Psychology: Faculty Publications

The parent-child relationship undergoes substantial reorganization over the transition to adolescence. Navigating this change is a challenge for parents because teens desire more behavioral autonomy as well as input in decision-making processes. Although it has been demonstrated that changes in parental socialization approaches facilitates adolescent adjustment, very little work has been devoted to understanding the underlying mechanisms supporting parents’ abilities to adjust caregiving during this period. Guided by self-regulation models of parenting, the present study examined how parental physiological and cognitive regulatory capacities were associated with hostile and insensitive parent conflict behavior over time. From a process-oriented perspective, we tested …

Electrospun Thymosin Beta-4 Loaded Plga/Pla Nanofiber/ Microfiber Hybrid Yarns For Tendon Tissue Engineering Application, Shaohua Wu, Rong Zhou, Fang Zhou, Philipp N. Streubel, Shaojuan Chen, Bin Duan

Department of Mechanical and Materials Engineering: Faculty Publications

Microfiber yarns (MY) have been widely employed to construct tendon tissue grafts. However, suboptimal ultrastructure and inappropriate environments for cell interactions limit their clinical application. Herein, we designed a modified electrospinning device to coat poly(lactic-co-glycolic acid) PLGA nanofibers onto polylactic acid (PLA) MY to generate PLGA/PLA hybrid yarns (HY), which had a well-aligned nanofibrous structure, resembling the ultrastructure of native tendon tissues and showed enhanced failure load compared to PLA MY. PLGA/PLA HY significantly improved the growth, proliferation, and tendon-specific gene expressions of human adipose derived mesenchymal stem cells (HADMSC) compared to PLA MY. Moreover, thymosin beta-4 (Tβ4) loaded PLGA/PLA …

Additive Manufacturing Of Magnesium Alloys, Rakeshkumar Karunakaran, Sam Ortgies, Ali Tamayol, Florin Bobaru, Michael P. Sealy

Department of Mechanical and Materials Engineering: Faculty Publications

Magnesium alloys are a promising new class of degradable biomaterials that have a similar stiffness to bone, which minimizes the harmful effects of stress shielding. Use of biodegradable magnesium implants eliminates the need for a second surgery for repair or removal. There is a growing interest to capitalize on additive manufacturing's unique design capabilities to advance the frontiers of medicine. However, magnesium alloys are difficult to 3D print due to the high chemical reactivity that poses a combustion risk. Furthermore, the low vaporization temperature of magnesium and common biocompatible alloying elements further increases the difficulty to print fully dense structures …

3d Printing Of Multilayered Scaffolds For Rotator Cuff Tendon Regeneration, Xiping Jiang, Shaohua Wu, Mitchell Kuss, Yunfan Kong, Wen Shi, Philipp N. Streubel, Tieshi Li, Bin Duan

Department of Mechanical and Materials Engineering: Faculty Publications

Repairing massive rotator cuff tendon defects remains a challenge due to the high retear rate after surgical intervention. 3D printing has emerged as a promising technique that enables the fabrication of engineered tissues with heterogeneous structures and mechanical properties, as well as controllable microenvironments for tendon regeneration. In this study, we developed a new strategy for rotator cuff tendon repair by combining a 3D printed scaffold of polylactic-co-glycolic acid (PLGA) with cell-laden collagen-fibrin hydrogels. We designed and fabricated two types of scaffolds: one featuring a separate layer-by-layer structure and another with a tri-layered structure as a whole. Uniaxial tensile tests …

Energy Development And Production In The Great Plains: Implications And Mitigation Opportunities, Jacqueline P. Ott, Bruce B. Hanberry, Mona Khalil, Mark W. Paschke, Max Post Van Der Burg, A.J. Prenni

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Energy is an integral part of society. The major US energy sources of fossil fuels (coal, oil, natural gas); biofuels (ethanol); and wind are concentrated in grassland ecosystems of the Great Plains. As energy de- mand continues to increase, mounting pressures will be placed on North American grassland systems. In this review, we present the ecological effects of energy development and production on grassland sys- tems. We then identify opportunities to mitigate these effects during the planning, construction, and pro- duction phases by using informed methodology and improved technology. Primary effects during energy development include small- and large-scale soil disturbance …

King, Joshua Wiese, David M. Baasch, Greg D. Wright, Mary Harner, Aaron T. Pearse, Matt Raabe, Dana Varner, Brice Krohn, Nicole Arcilla, Kirk D. Schroeder, Kenneth F. Dinan

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Over 80% of the Mid-Continent Sandhill Crane (Antigone canadensis) Population (MCP), estimated at over 660,000 individuals, stops in the Central Platte River Valley (CPRV) during spring migration from mid-February through mid-April. Research suggests that the MCP may be shifting its distribution spatially and temporally within the CPRV. From 2002 to 2017, we conducted weekly aerial surveys of Sandhill Cranes staging in the CPRV to examine temporal and spatial trends in their abundance and distribution. Then, we used winter temperature and drought severity measures from key wintering and early migratory stopover locations to assess the impacts of weather patterns …

The Kaposi’S Sarcoma-Associated Herpesvirus (Kshv) Gh/Gl Complex Is The Predominant Neutralizing Antigenic Determinant In Kshv-Infected Individuals, Yasaman Mortazavi, Salum J. Lidenge, Tara Tran, John T. West, Charles Wood, For Yue Tso

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma-associated herpesvirus (KSHV) is the etiological agent of Kaposi’s sarcoma (KS), one of the most prevalent cancers of people living with HIV/AIDS in sub-Saharan Africa. The seroprevalence for KSHV is high in the region, and no prophylactic vaccine against the virus is available. In this study, we characterized the antigenic targets of KSHV-specific neutralizing antibodies (nAbs) in asymptomatic KSHV-infected individuals and KS patients with high nAbs titers. We quantified the extent to which various KSHV envelope glycoproteins (gB, ORF28, ORF68, gH, gL, gM, gN and gpK8.1) adsorbed/removed KSHV-specific nAbs from the plasma of infected individuals. Our study revealed that …

Epstein Barr Virus-Immortalizedｂlymphocytes Exacerbate Experimental Autoimmune Encephalomyelitis In Xenograft Mice, Pascal Polepole, Alison Bartenslager, Yutong Liu, Thomas M. Petro, Samodha C. Fernando, Luwen Zhang

Nebraska Center for Virology: Faculty Publications

Multiple sclerosis (MS) is the most common autoimmune disorder affecting the central nervous system. Epstein-Barr virus (EBV) is a causative agent for infectious mononucleosis (IM) that is associated with MS pathogenesis. However, the exact mechanism by which EBV, specifically in IM, increases the risk for MS remains unknown. EBV immortalizes primary B lymphocytes in vitro and causes excessive B lymphocyte proliferation in IM in vivo. In asymptomatic carriers, EBV-infected B lymphocytes still proliferate to certain degrees, the process of which is tightly controlled by the host immune systems. Experimental autoimmune encephalomyelitis (EAE) mimics key features of MS in humans and …

Recommendations For Measuring Hiv Reservoir Size In Cure- Directed Clinical Trials., Luis J. Montaner, Qingsheng Li

Nebraska Center for Virology: Faculty Publications

Therapeutic strategies are being clinically tested either to eradicate the latent HIV reservoir or to achieve virologic control in the absence of antiretroviral therapy (ART). Attaining this goal will require a consensus on how best to measure the levels of persistently-infected cells with the potential to cause viral rebound upon ART cessation to assess the results of cure-directed strategies in vivo. Current measurements assess different aspects of the HIV provirus and its functionality, and produce divergent results. Here, we provide the collective insight and position from the BEAT-HIV Martin Delaney Collaboratory on which viral measurements to prioritize in HIV cure-directed …

Developing A Computer-Controlled Treat Dispenser For Canine Operant Conditioning, Walker Arce, Jeffrey R. Stevens

Jeffrey Stevens Publications

When performing canine operant conditioning studies, the delivery of the reward can be a limiting factor of the study. While there are a few commercially available options for automatically delivering rewards, they generally require manual input, such as using a remote control, in accordance with the experiment script. This means that human reaction times and transmission distances can cause interruptions to the flow of the experiment. The potential for development of non-supervised conditioning studies is limited by this same factor. To remedy this, we retrofitted an off-the-shelf treat dispenser with new electronics that allow it to be remotely controllable as …

Variation Profile Of The Orthotospovirus Genome, Deepti Nigam, Hernan Garcia Ruiz

Department of Plant Pathology: Faculty Publications

Orthotospoviruses are plant-infecting members of the family Tospoviridae (order Bunyavirales), have a broad host range and are vectored by polyphagous thrips in a circulative- propagative manner. Because diverse hosts and vectors impose heterogeneous selection constraints on viral genomes, the evolutionary arms races between hosts and their pathogens might be manifested as selection for rapid changes in key genes. These observations suggest that orthotospoviruses contain key genetic components that rapidly mutate to mediate host adaptation and vector transmission. Using complete genome sequences, we profiled genomic variation in orthotospoviruses. Results show that the three genomic segments contain hypervariable areas at homologous locations …

Uterine Torsion Dystocia Complicated By Perosomus Elumbis In An Angus Calf Associated With A Consanguineous Mating, Alyssa B. Helms, Riley E. Thompson, Sam Lawton, Jessica L. Petersen, Allison Watson, Mee-Ja Sula, David J. Steffen, Brian K. Whitlock

School of Veterinary and Biomedical Sciences: Faculty Publications

A six-year-old multiparous Angus cow was presented for dystocia. Vaginal and rectal examinations revealed an approximately 360° counterclockwise uterine torsion. The torsion was corrected by rolling the cow counterclockwise (three episodes) with the aid of a plank coupled with manual detorsion via the vagina. The placement of obstetric chains followed by manual traction ultimately delivered a stillborn male calf with evidence of vertebral aplasia, arthrogryposis, and abdominal organ herniation. Patient history and subsequent parentage verification revealed that the calf was the result of a consanguineous (mother to son) mating. Tissue samples from the affected calf and blood samples from the …

Identification Of Immunogenic Epitopes That Permit The Detection Of Antigen-Specific T Cell Responses In Multiple Serotypes Of Group B Coxsackievirus Infections, Ninaad Lasrado, Arunakumar Gangaplara, Rajkumar Arumugam, Chandirasegara Massilamany, Sayli Pokal, Yuzhen Zhou, Shi-Hua Xiang, David Steffen, Jay Reddy

School of Veterinary and Biomedical Sciences: Faculty Publications

Coxsackievirus group B (CVB) contains six serotypes that can affect various organs. Some of these organ-specific diseases such as myocarditis and pancreatitis can be caused by more than one serotype. Thus, development of immunological tools common to multiple serotypes is desired. This is especially critical for analyzing antigen-specific T cell responses at a single cell level. To this end, we made efforts to identify the immunogenic epitopes of CVB3 leading us to localize three T cell epitopes within the viral protein 1 (VP1) namely, VP1 681–700, VP1 721–740 and VP1 771–790. First, we confirmed their immunogenicity in the immunization settings. …

Recent Advances In The Diagnosis Of Classical Swine Fever And Future Perspectives, Lihua Wang, Rachel Madera, Yuzhen Li, D. Scott Mcvey, Jishu Shi

School of Veterinary and Biomedical Sciences: Faculty Publications

Classical swine fever (CSF) is a highly contagious viral disease of pigs, including wild boar. It is regarded as one of the major problems in the pig industry as it is still endemic in many regions of the world and has the potential to cause devastating epidemics, particularly in countries free of the disease. Rapid and reliable diagnosis is of utmost importance in the control of CSF. Since clinical presentations of CSF are highly variable and may be confused with other viral diseases in pigs, laboratory diagnosis is indispensable for an unambiguous diagnosis. On an international level, well-established diagnostic tests …
