Displaying And Delivering Viral Membrane Antigens Via Ww Domain–Activated Extracellular Vesicles, Sengjin Choi, Zhiping Yang, Qiyu Wang, Zhi Qiao, Maoyun Sun, Joshua Wiggins, Shi-Hua Xiang, Quan Lu

Nebraska Center for Virology: Faculty Publications

Membrane proteins expressed on the surface of enveloped viruses are conformational antigens readily recognized by B cells of the immune system. An effective vaccine would require the synthesis and delivery of these native conformational antigens in lipid membranes that preserve specific epitope structures. We have created an extracellular vesicle–based technology that allows viral membrane antigens to be selectively recruited onto the surface of WW domain–activated extracellular vesicles (WAEVs). Budding of WAEVs requires secretory carrier-associated membrane protein 3, which through its proline-proline-alanine-tyrosine motif interacts with WW domains to recruit fused viral membrane antigens onto WAEVs. Immunization with influenza and HIV viral …

Vaccines Against Group B Coxsackieviruses And Their Importance, Kiruthiga Mone, Ninaad Lasrado, Meghna Sur, Jay Reddy

School of Veterinary and Biomedical Sciences: Faculty Publications

The group B coxsackieviruses (CVBs) exist in six serotypes (CVB1 to CVB6). Disease associations have been reported for most serotypes, and multiple serotypes can cause similar diseases. For example, CVB1, CVB3, and CVB5 are generally implicated in the causation of myocarditis, whereas CVB1 and CVB4 could accelerate the development of type 1 diabetes (T1D). Yet, no vaccines against these viruses are currently available. In this review, we have analyzed the attributes of experimentally tested vaccines and discussed their merits and demerits or limitations, as well as their impact in preventing infections, most importantly myocarditis and T1D.

Soil Microbial Legacies Influence Freeze–Thaw Responses Of Soil, Melissa A. Pastore, Aimee T. Classen, Marie E. English, Serita D. Frey, Melissa A. Knorr, Karin Rand, E. Carol Adair

Faculty Publications

Warmer winters with less snowfall are increasing the frequency of soil freeze–thaw cycles across temperate regions. Soil microbial responses to freeze–thaw cycles vary and some of this variation may be explained by microbial conditioning to prior winter conditions, yet such linkages remain largely unexplored. We investigated how differences in temperature history influenced microbial community composition and activity in response to freeze–thaw cycles.

We collected soil microbial communities that developed under colder (high elevation) and warmer (low elevation) temperature regimes in spruce-fir forests, then added each of these soil microbial communities to a sterile bulk-soil in a laboratory microcosm experiment. The …

Living As A Dying Child: A Gadamerian Analysis Of The Poetry Of Mattie J. T. Stepanek, Corinne A. Settecase-Wu

Dissertations

Yearly, approximately 500,000 children live with life-limiting conditions in the United States; 50,000 die. Yet, details regarding children's days of living as dying are unknown. The aim of this qualitative hermeneutic study is to gain understanding of the phenomenon of living as a dying child. A Gadamerian-inspired approach was implemented to underpin the study, and to analyze poetic text to address the research question: What is it to be living as a dying child? The text sample included 499 poems written by Mattie J. T. Stepanek, a dying child. The Settecase-Wu Conceptual Guide was developed and implemented to ensure …

Washoe Cty. Human Servs. V. Dist. Ct., 138 Nev. Adv. Op. 87 (Dec. 29, 2022), Rachel Blum

Nevada Supreme Court Summaries

The Nevada Supreme Court considered this writ of mandamus as it held substantial precedential value and was a matter of first impression. Although the controversy was moot, they decided to hear the issue, as the duration of the challenges action is relatively short and a similar issue is likely to arise in the future. Further, the Court found the matter to be important, because the issue related to the protection of Nevada children. The Court held that NRS 432B.393(3)(c) is constitutional, as it does not infringe on the due process rights of parents concerning the altering or termination of custody …

Inhibition Of Colorectal Cancer Tumorigenesis By Ursolic Acid And Doxorubicin Is Mediated By Targeting The Akt Signaling Pathway And Activating The Hippo Signaling Pathway, Dan Hu, Ruo Yu Meng, Thi Van Nguyen, Ok Hee Chai, Byung Hyun Park, Ju-Seog Lee, Soo Mi Kim

Faculty, Staff and Student Publications

Colorectal cancer (CRC) is one of the deadliest malignant tumors worldwide and its prevalence is increasing in South Korea. The efficacy of combined treatment with natural product‑derived and chemotherapy agents including curcumin combined with 5‑fluorouracil, resveratrol combined with cisplatin and epigallocatechin‑3‑gallate (EGCG) combined with cisplatin in preventing cancer progression and killing cancer cells has emerged. The Akt and Hippo signaling pathways serve a key role in colorectal tumor growth; however, the exact role of the crosstalk between Akt and Hippo signaling pathways in CRC remains poorly elucidated. The combined effect of UA and DOX on the cell proliferation, apoptosis, migration …

Faculty, Staff and Student Publications

Globally, dental caries is one of the most common non-communicable diseases for patients of all ages; Streptococcus mutans (S. mutans) is its principal pathogen. Lactobacillus paracasei (L. paracasei) shows excellent anti-pathogens and immune-regulation functions in the host. The aim of this study is to evaluate the effects of L. paracasei ET-22 on the formation of S. mutans biofilms. The living bacteria, heat-killed bacteria, and secretions of L. paracasei ET-22 were prepared using the same number of bacteria. In vitro, they were added into artificial-saliva medium, and used to coculture with the S. mutans. Results showed …

Harmful Speech And The Covid-19 Penumbra, Kenneth Grad, Amanda Turnbull

Canadian Journal of Law and Technology

We make two central claims in this essay. First, the themes of malinformation have remained remarkably consistent across pandemics. What has changed is only the manner of their spread through evolving technologies and globalization. Thus, as with pandemic preparedness more generally, our failure to take proactive measures reflects a failure to heed the lessons of the past. Second, we argue that the COVID-19 pandemic presents a unique opportunity to tackle online falsehoods and mitigate their impact in the future.

We proceed in three parts. Part one addresses the harmful speech that inevitably follows in pandemic’s wake. We illustrate this through …

Monitoring Fluid Migration Using In-Situ Nuclear Magnetic Resonance Core Flooding System Integrated With Fiber Optic Sensors: A Proof Of Concept, Bruno Da Silva Falcão, Lionel Esteban, Ausama Giwelli, Yevhen Kovalyshen, Stephen Banks, Ahmed Al-Yaseri, Alireza Keshavarz, Stefan Iglauer

Research outputs 2022 to 2026

In-situ nuclear magnetic resonance (NMR) core flooding system has enabled researchers to monitor several rock properties such as porosity, pore size distribution, and fluid saturation along the tested samples with high resolutions and under reservoir conditions. However, spatially resolved rock strength/mechanical property alteration coupled to fluid migration/substitution remains poorly characterized. To this end, Fiber Bragg Grating (FBG) multiplex sensors were integrated with NMR core flooding system to monitor rock strength changes, or generally speaking, to observe hydro-mechanical-chemical coupling mechanisms during core flooding tests. In this study, we present a novel approach on how to conduct core flooding experiments, while simultaneously …

Drug Specificity And Affinity Are Encoded In The Probability Of Cryptic Pocket Opening In Myosin Motor Domains, Artur Meller, Jeffrey M Lotthammer, Louis G Smith, Borna Novak, Lindsey A Lee, Catherine C Kuhn, Lina Greenberg, Leslie A Leinwand, Michael J Greenberg, Gregory R Bowman

2020-Current year OA Pubs

The design of compounds that can discriminate between closely related target proteins remains a central challenge in drug discovery. Specific therapeutics targeting the highly conserved myosin motor family are urgently needed as mutations in at least six of its members cause numerous diseases. Allosteric modulators, like the myosin-II inhibitor blebbistatin, are a promising means to achieve specificity. However, it remains unclear why blebbistatin inhibits myosin-II motors with different potencies given that it binds at a highly conserved pocket that is always closed in blebbistatin-free experimental structures. We hypothesized that the probability of pocket opening is an important determinant of the …

Gold Nanoparticle-Enhanced X-Ray Microtomography Of The Rodent Reveals Region-Specific Cerebrospinal Fluid Circulation In The Brain, Shelei Pan, Peter H Yang, Dakota Defreitas, Sruthi Ramagiri, Peter O Bayguinov, Carl D Hacker, Abraham Z Snyder, Jackson Wilborn, Hengbo Huang, Gretchen M Koller, Dhvanii K Raval, Grace L Halupnik, Sanja Sviben, Rui Tang, Gabriel Haller, James D Quirk, James A J Fitzpatrick, Prabagaran Esakky, Jennifer M Strahle, Et Al.

Cerebrospinal fluid (CSF) is essential for the development and function of the central nervous system (CNS). However, the brain and its interstitium have largely been thought of as a single entity through which CSF circulates, and it is not known whether specific cell populations within the CNS preferentially interact with the CSF. Here, we develop a technique for CSF tracking, gold nanoparticle-enhanced X-ray microtomography, to achieve micrometer-scale resolution visualization of CSF circulation patterns during development. Using this method and subsequent histological analysis in rodents, we identify previously uncharacterized CSF pathways from the subarachnoid space (particularly the basal cisterns) that mediate …

Seeing In The Dark: A Review Of The Use Of Side-Scan Sonar To Detect And Study Manatees, With An Emphasis On Latin America, Daniel Gonzalez-Socoloske, León David Olivera-Gómez

Faculty Publications

Manatees are aquatic mammals that live in a variety of environments. Many of those shallow water environments have murky water, making detection using traditional visual surveys very challenging. Side-scan sonar was first proposed as a tool to detect and study manatees in these complicated habitats in 2005. Here, we summarize the use of this tool from 2005 to 2022 by searching the available literature. Our literature search revealed that this tool is being widely used in more than 20 locations and over 15 countries. All three manatee species are being studied with side-scan sonar. It is most useful in murky …

Safety Of Adenosine For The Treatment Of Supraventricular Tachycardia In Hospitalized Patients With Covid-19 Pneumonia, T. Zivan, Ramon L Ruiz, Alexandre Martinez, Behzad B. Pavri

Department of Medicine Faculty Papers

Coronavirus disease 2019 (COVID-19) is associated with pulmonary involvement and cardiac arrhythmias, including supraventricular tachycardia (SVT). Adenosine is commonly used to treat SVT and is generally safe, but is rarely associated with bronchospasm. There are no data regarding the safety of adenosine use in patients with COVID-19 pneumonia and physicians may hesitate to use it in such patients. We surveyed resident physicians and cardiology attendings regarding their level of comfort in administering adenosine to hospitalized COVID-19 patients. We compared a study group of 42 COVID-19 hospitalized patients who received adenosine for SVT to a matched (for age, sex, and co-morbidities) …

“Do Not Ever Refer To My Lord Jesus Christ With Pronouns”: Considering Controversies Over Religiously Motivated Discrimination On The Basis Of Gender Identity, Linda C. Mcclain

Faculty Scholarship

In the by-now familiar framing “religious freedom versus LGBT+ rights,” perhaps the most visible conflicts today in the United States, and elsewhere, concern the “T”—transgender or gender identity rights. This issue of the Journal of Law and Religion includes a conversation in print between Patrick Parkinson, Laura Portuondo and Claudia Haupt, and Shannon Gilreath on this timely topic, and their contrasting perspectives mirror dimensions of the larger public controversies. Although tweets like those quoted above (by unsuccessful Republican congressional candidate Lavern Spicer) asserting that neither the Bible nor Jesus had pronouns sparked both factual corrections and comical retorts, ³ the …

Dosimetric Impact Of Lesion Number, Size, And Volume On Mean Brain Dose With Stereotactic Radiosurgery For Multiple Brain Metastases, Alonso La Rosa De Los Rios, D Jay Wieczorek, Ranjini Tolakanahalli, Cecilia Lee, Tugce Kutuk, Matthew Hall, Michael Mcdermott, Minesh Mehta, Alonso Gutierrez, Rupesh Kotecha

We evaluated the effect of lesion number and volume for brain metastasis treated with SRS using GammaKnife® ICON™ (GK) and CyberKnife® M6™ (CK). Four sets of lesion sizes (<5 mm, 5-10 mm, >10-15 mm, and >15 mm) were contoured and prescribed a dose of 20 Gy/1 fraction. The number of lesions was increased until a threshold mean brain dose of 8 Gy was reached; then individually optimized to achieve maximum conformity. Across GK plans, mean brain dose was linearly proportional to the number of lesions and total GTV for all sizes. The numbers of lesions needed to reach this threshold for GK were …

Integration Of Transcriptome-Wide Association Study With Neuronal Dysfunction Assays Provides Functional Genomics Evidence For Parkinson’S Disease Genes, Jiayang Li, Bismark Kojo Amoh, Emma Mccormick, Akash Tarkunde, Katy Fan Zhu, Alma Perez, Megan Mair, Justin Moore, Joshua M Shulman, Ismael Al-Ramahi, Juan Botas

Faculty, Staff and Students Publications

Genome-wide association studies (GWAS) have markedly advanced our understanding of the genetics of Parkinson's disease (PD), but they currently do not account for the full heritability of PD. In many cases it is difficult to unambiguously identify a specific gene within each locus because GWAS does not provide functional information on the identified candidate loci. Here we present an integrative approach that combines transcriptome-wide association study (TWAS) with high-throughput neuronal dysfunction analyses in Drosophila to discover and validate candidate PD genes. We identified 160 candidate genes whose misexpression is associated with PD risk via TWAS. Candidates were validated using orthogonal …

A Pilot Study On Cannabidiol (Cbd) And Eccentric Exercise: Impact On Inflammation, Performance, And Pain, Whitley J. Stone, Danilo Tolusso, Guillermo Pacheco, Shea M. Brgoch, Van T. Nguyen

International Journal of Exercise Science

International Journal of Exercise Science 16(2): 109-117, 2023. Cannabidiol (CBD) is a non-psychoactive cannabinoid purported to reduce symptoms of discomfort. Individuals are now using CBD to treat symptoms of multiple sclerosis, seizures, and chronic pain. Animal models indicate that CBD may be effective at reducing inflammation post fatiguing exercise. However, little evidence is available to evaluate these findings in humans. Therefore, the purpose of this investigation was to evaluate the impact of two doses of CBD oil on inflammation (IL-6), performance, and pain after an eccentric loading protocol. Participants (n = 4) participated in three conditions (placebo, low dose, …

School of Natural Resources: Faculty Publications

Using samples spanning 10-degrees of latitude in Alaska, we provide the first comparative assessment of avian haemosporidia distribution of Arctic Alaska with subarctic host populations for four species of grouse and three species of ptarmigan (Galliformes). We found a high overall prevalence for at least one haemospordian genus (88%; N = 351/400), with spruce grouse (Canachites canadensis) showing the highest prevalence (100%; N = 54/ 54). Haemoproteus and Plasmodium lineages were only observed within grouse, while Leucocytozoon species were found within both grouse and ptarmigan. Further, different Leucocytozoon lineages were obtained from blood and tissue samples from the …
