Assessing Genomic Literacy In Advanced Practice Nursing Students Before And After An Intervention, Guiselle Palomera

Doctor of Nursing Practice Final Manuscripts

Introduction

The purpose of this evidence-based Doctor of Nursing Practice (DNP) project was to examine genetics and genomics literacy in advanced practice nursing students before and after an intervention.

Background

As genomics continue to play an emerging role in healthcare, and advancements are introduced into clinical practice, it is critical that nurses be competent in genetics and genomics concepts. There is a fundamental need to incorporate genomics education into nursing school curriculum. However, studies have shown that the majority of faculty across nursing schools in the United States are ill-equipped to teach genetics and genomics concepts. Furthermore, many interventions to …

Identification And Initial Characterization Of Hfq-Associated Srnas In Histophilus Somni Strain 2336, Bindu Subhadra, Dianjun Cao, Roderick Jensen, Clayton Caswell, Thomas J. Inzana

Faculty Publications - Biological Sciences

Small RNAs (sRNA), in association with the global chaperone regulator Hfq, positively or negatively regulate gene expression in bacteria. For this study, Histophilus somni sRNAs that bind to Hfq were identified and then partially characterized. The Hfq-associated sRNAs in H. somni were isolated and identified by co-immunoprecipitation using anti-Hfq antibody, followed by sRNA sequencing. Sequence analysis of the sRNA samples identified 100 putative sRNAs, out of which 16 were present in pathogenic strain 2336, but not in non-pathogenic strain 129Pt. Bioinformatic analyses suggested that the sRNAs HS9, HS79, and HS97 could bind to many genes putatively involved in virulence/biofilm formation. …

Serological Prevalence Of Crimean–Congo Hemorrhagic Fever Virus Infection In Small Ruminants And Cattle In The Gambia, Jerusha Matthews, Arss Secka, David Scott Mcvey, Kimberly A. Dodd, Bonto Faburay

School of Veterinary and Biomedical Sciences: Faculty Publications

Crimean–Congo hemorrhagic fever virus (CCHFV) is a widely distributed tickborne zoonotic agent that infects a variety of host species. There is a lack of information on the true geographic distribution of the prevalence and risk of CCHFV in West Africa. A countrywide cross-sectional study involving 1413 extensively managed indigenous small ruminants and cattle at livestock sales markets and in village herds, respectively, was carried out in The Gambia. In sheep, an overall anti-CCHFV antibody prevalence of 18.9% (95% CI: 15.5–22.8%), goats 9.0% (95% CI: 6.7–11.7%), and cattle 59.9% (95% CI: 54.9–64.7%) was detected. Significant variation (p < 0.05) in the prevalence of anti-CCHFV antibodies at sites in the five administrative regions (sheep: 4.8–25.9%; goats: 1.8–17.1%) and three agroecological zones (sheep: 8.9–32.9%; goats: 4.1–18.0%) was also observed. Comparatively, higher anti-CCHFV antibody prevalence was detected in cattle (33.3–84.0%) compared to small ruminants (1.8–8.1%). This study represents the first countrywide investigation of the seroprevalence of CCHFV in The Gambia, and the results suggest potential circulation and endemicity of the virus in the country. These data provide critical information vital to the development of informed policies for the surveillance, diagnosis, and control of CCFHV infection in The Gambia and the region.

The Role Of Complement In Stroke And Traumatic Brain Injury, Christine Couch

MUSC Theses and Dissertations

Brain and neural injury are a non-specific disease category that includes traumatic brain injury (TBI) and stroke. Both TBI and stroke are common, costly, and leading causes of severe disability in adults. Both stroke and TBI are responsible for substantial disability in working age adults, with stroke being the second leading cause of death worldwide [1] and TBI a major cause of disability in people younger than their 40's [2]. The immune response after brain injury is multifactorial and involves both local and systemic events at the cellular and molecular level. The complement system is a component of both the …

Agricultural and Environmental Sciences Faculty Research

Global food security is a worldwide concern. Food insecurity is a significant threat to poverty and hunger eradication goals. Agriculture is one of the focal points in the global policy agenda. Increases in agricultural productivity through the incorporation of technological advances or expansion of cultivable land areas have been pushed forward. However, production growth has slowed in many parts of the world due to various endemic challenges, such as decreased investment in agricultural research, lack of infrastructure in rural areas, and increasing water scarcity. Climate change adversities in agriculture and food security are increasing. Recently, the COVID-19 pandemic has severely …

Demystifying The Mind-Body Connection: The Neuroscience Behind How Thoughts Impact Physical Health, Sofia Pantis

Undergraduate Honors Theses

The beliefs, emotions, and experiences that constitute a mindset shape numerous aspects of one’s reality, but in particular, health. Health is defined by not only the physical state of one’s body, but also the content of one’s mind. The integration of the mind and body is often associated with naturopathic medicines or pseudoscience, and thus is usually left out of Western medicinal practices. This review aims to demystify the mind-body connection in health and wellness by introducing it within an empirical, neuroscientific landscape. This research supports the hypothesis that mind over matter rings true even at the biochemical level. Activation …

Influenza C virus (ICV) is increasingly associated with community-acquired pneumonia (CAP) in children and its disease severity is worse than the influenza B virus, but similar to influenza A virus associated CAP. Despite the ubiquitous infection landscape of ICV in humans, little is known about its replication and pathobiology in animals. The goal of this study was to understand the replication kinetics, tissue tropism, and pathogenesis of human ICV (huICV) in comparison to the swine influenza D virus (swIDV) in guinea pigs. Intranasal inoculation of both viruses did not cause clinical signs, however, the infected animals shed virus in nasal …

Adenoviral-Vectored Epigraph Vaccine Elicits Robust, Durable, And Protective Immunity Against H3 Influenza A Virus In Swine, Erika M. Petro-Turnquist, Matthew J. Pekarek, Nicholas Jeanjaquet, Cedric Wooledge, David J. Steffen, Hiep Vu, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Current methods of vaccination against swine Influenza A Virus (IAV-S) in pigs are infrequently updated, induce strain-specific responses, and have a limited duration of protection. Here, we characterize the onset and duration of adaptive immune responses after vaccination with an adenoviral-vectored Epigraph vaccine. In this longitudinal study we observed robust and durable antibody responses that remained above protective titers six months after vaccination. We further identified stable levels of antigen-specific T cell responses that remained detectable in the absence of antigen stimulation. Antibody isotyping revealed robust class switching from IgM to IgG induced by Epigraph vaccination, while the commercial comparator …

The Influence Of The Gut Microbiota On Asthma In School-Aged Children And Adults, Naomi Grace Wilson

Arts & Sciences Graduate Student Theses and Dissertations

Asthma is a common respiratory disease with a highly heterogeneous pathophysiology. The human gut microbiota, comprising of all the microorganisms that inhabit the gastrointestinal tract, is linked to the development of asthma and can alter airway inflammation in animal models. The idea that the gut microbiota can have bidirectional cross-talk with the lung, such as gut dysbiosis affecting lung disease, is termed the gut-lung axis. While the gut microbiota of early life has been an area of particular interest for asthma pathogenesis research, the effect of its taxonomic and functional composition after asthma diagnosis is less clear. This dissertation employs …

Evaluating The Impact Of Temperature And Artificial Light At Night On The Growth, Swimming Performance, And Corticosterone Levels Of Southern Leopard Frog (Lithobates Sphenocephalus) Tadpoles, Skylar Alexander

Honors Theses

Anthropogenic activities caused by urbanization have considerably altered our world’s ecosystems which has led to a global amphibian population decline. Encroaching and unyielding urbanization by humans has contributed to a rise in artificial light at night due to light pollution as well as increased temperature due to climate change. Both rising temperatures and artificial light at night (ALAN) have been shown to individually have negative effects on amphibian physiology such as increased stress and decreased behavior. However, due to the drastic nature of human imposition, amphibians typically encounter these anthropogenic stressors in combination. Therefore, it is important to understand how …

The induction of partial tolerance toward pancreatic autoantigens in the treatment of type 1 diabetes mellitus (T1DM) can be attained by autologous hematopoietic stem cell transplantation (HSCT). However, most patients treated by autologous HSCT eventually relapse. Furthermore, allogeneic HSCT which could potentially provide a durable non-autoimmune T-cell receptor (TCR) repertoire is associated with a substantial risk for transplant-related mortality. We have previously demonstrated an effective approach for attaining engraftment without graft versus host disease (GVHD) of allogeneic T-cell depleted HSCT, following non-myeloablative conditioning, using donor-derived anti-3rd party central memory CD8 veto T cells (Tcm). In the present study, we investigated …

BACKGROUND: Assessment for risks associated with acute stable COVID-19 is important to optimize clinical trial enrollment and target patients for scarce therapeutics. To assess whether healthcare system engagement location is an independent predictor of outcomes we performed a secondary analysis of the ACTIV-4B Outpatient Thrombosis Prevention trial.

METHODS: A secondary analysis of the ACTIV-4B trial that was conducted at 52 US sites between September 2020 and August 2021. Participants were enrolled through acute unscheduled episodic care (AUEC) enrollment location (emergency department, or urgent care clinic visit) compared to minimal contact (MC) enrollment (electronic contact from test center lists of positive …

Individual And Social Influences On Cigarette Smoking During Pregnancy, Alexandra Noel Houston-Ludlam

Arts & Sciences Graduate Student Theses and Dissertations

Population-level trends on sociodemographic risk factors for cigarette smoking during pregnancy (SDP) and outcomes for offspring exposed to maternal SDP are well established. However, the more complex task of understanding individual risk-prediction, including differences by maternal race/ethnicity, and its clinical application, remains incomplete. Characterizing the relative influence of environmental and individual characteristics as risk or protective factors for continued SDP is a necessary next step for informing individual- and public health-level interventions to produce successful smoking cessation prior to pregnancy, substantially reducing smoking-related mortality in child-bearing people. In this dissertation, I wanted to explore how multiple levels of influence, from …

The Microbes Within: Pathogen In-Host Adaptation And The Gut Microbiome During Persistent Colonization And Recurrent Infection, Joohee Choi

Arts & Sciences Graduate Student Theses and Dissertations

Microbes not just surround us; they are inside of us. The gut microbiome has emerged in recent years as an important modulator of health and is thought to have co-evolved with us throughout evolutionary history. On the other hand, our immune systems are constantly surveilling and battling infection by external pathogens— some of which still manage to evade our immune response and colonize our bodies long-term. In this Thesis, I investigated microbes inhabiting our bodies in various contexts to understand their impact on human health.In Chapter 2, I discuss the effects of fecal microbiome transplant (FMT) study drug RBX2660 on …

Identifying Molecular Targets Of Adar1 Dependency In Breast Cancer, Sua Ryu

Arts & Sciences Graduate Student Theses and Dissertations

Innate immunity is a fundamental defense mechanism against non-self. Similar to its role in pathogenic infections, innate immunity is capable of eliminating cancerous cells by activating cytotoxic inflammatory signaling. Adenosine deaminase acting on RNA 1 (ADAR1) is a key regulator of cell-intrinsic innate immunity. ADAR1 converts adenosines to inosines on double-stranded RNAs (dsRNAs), altering dsRNA structure and its interactive properties. This suppresses cytoplasmic sensing of immunogenic dsRNA and activation of the type I interferon (IFN) signaling pathway. Frequently, suppressing endogenous dsRNA from triggering cytotoxic inflammatory signaling is essential for cancer cell survival. This is known as ADAR1 dependency, which has …

Influence Of Environmental Gradients On Genomic Variation In Pediatric Commensals And Pathogens, Sanjam Sawhney

Arts & Sciences Graduate Student Theses and Dissertations

Microbes interact with humans in a myriad of ways. They come together in the human gut to form complex communities that collectively transform and individually evolve in response to changing environmental conditions. Individual microbes can also cause human infection and escape antibiotic clearance through acquisition and development of novel resistance mechanisms. In this thesis, I chronicle the relationships between microbes and humans across two axes: from complex communities to single isolates, and from targeted studies of pediatric populations vulnerable to microbiome perturbations and pathogen challenge, to broader human and animal cohorts spanning colonizing and diagnostic environments.In Chapter 2, I extensively …

The Effects Of Aloe Vera On The Human Gut Microbiome, Samantha Leon

Honors Theses

The human gut microbiome is a diverse community of bacteria influenced by multiple factors including host age, geographical location, and diet. This study observed the effects of aloe vera juice on the human gut microbiome. Fecal samples were taken every two weeks over a period of one year; the subject consumed aloe vera juice in alternating cycles of consumption “on” and abstaining “off” with each cycle lasting for eight weeks. The bacterial community in each sample was characterized using 16S rRNA gene sequencing. Sequences were identified and their relative abundances were used to look for patterns distinguishing “on” and “off” …

The Development Of A Primer Payload With Microparticles For Uti Pathogen Identification Using Polythymidine- Modified Lamp Primers In Droplet Lamp, Jonas Otoo

KGI Theses and Dissertations

Nucleic acid amplification tests (NAATs) are among the diagnostic tests with the highest sensitivity and specificity. However, they are more complex to develop than other diagnostic tests such as biochemical tests and lateral flow immunoassay tests. Polymerase chain reaction (PCR) is the gold standard for NAATs. PCR requires thermal cycling to achieve clonal amplification of the target pathogen DNA for diagnosis. Thermal cycling poses a challenge in the development of PCR diagnostics for point-of-care (POC) settings. Loop-mediated isothermal amplification (LAMP) offers an isothermal method for NAATs diagnostics. The advancement of the microfluidics field significantly enhances the development of LAMP diagnostics …

Neuroinflammatory And Metabolomic Temporal Dynamics From Inhaled Wildfire Smoke With Attenuation Via Pharmacological Intervention, David Scieszka

Biomedical Sciences ETDs

Wildfire smoke is a global issue affecting nearly all humans on the surface of this Earth. Smoke dispersion from wildfires can span continents and cross oceans with amazing ease. Furthermore, total acres of land burned per year in the United States has roughly doubled since 1980, meaning this issue will persist for an indeterminate amount of time. Exposure to wildfire smoke is hazardous and promotes aging-associated events in the cardiopulmonary systems. Yet long- and short-term effects on the brain remain relatively unknown. From these, it is critically important to understand the neurological impacts from wildfire smoke exposure; to compare these …

Effects Of Sampling Methodologies On Mycoplasma Gallisepticum Tissue Populations In Commercial Layer Pullets, Sethulakshmi Kattupparayil Sasidharan

Theses and Dissertations

Mycoplasma gallisepticum (MG) can cause chronic respiratory disease in chickens and infectious sinusitis in turkeys. Impacts of MG infections can include increased morbidity and mortality, decreased egg production, hatchability and feed efficiency. Biosecurity and bio-surveillance remain the primary means of deterrence as the current means of control are not wholly effective. Further applications towards the characterization of MG-related disease control requires proper understanding of the characteristics of MG infections with accurate and efficient quantification of in vivo MG populations. To this end, study was conducted to determine the in vivo MG populations in infected pullets and to determine impact of …

Host-Acquired Virus Genes Support An Ancient Antiviral Role Of The Pirna Pathway In Dipterans, Rebecca Christian

Theses and Dissertations

Endogenous viral elements (EVEs) have been recently investigated as a source of transgenerational immune memory. These “viral fossils” are abundant in Aedes mosquitoes and partner with the host’s primary antiviral defense system, the RNA interference (RNAi) pathways. This partnership appears unique to mosquitoes, which encode an expansion of the Piwi endoribonucleases. To interrogate EVE-Piwi partnerships and their role in antiviral defense, I performed a comparative small RNA analysis of two naturally occurring EVE-virus pairs – one in the mosquito Aedes albopictus, and one in the midge Chaoborus americanus. Both express an EVE related to the nucleoprotein of their …

Identifying Barriers To Data Use On U.S. Beef Cow-Calf Operations And Developing Solutions To Improve Cow-Calf Record-Keeping, William Isaac Jumper

Theses and Dissertations

Cattle health and production records (CHPR) are data collected by cattle producers and veterinarians in the form of measurements, observations, counts of events over time, and physiologic attributes that describe individual and group-level health and production. These data are useful to both veterinarians and cattle producers for making evidence-based decisions on cow-calf operations. Currently, there are no uniform, industry-wide methods of capturing and recording CHPR in the U.S. cow-calf industry. Although many cow-calf producers in the U.S. are thought to collect some form of CHPR, it is believed that relatively few are doing so in an electronic manner that facilitates …
