A Gene Expression Profile Associated With Successful Cns Axon Regeneration In Xenopus Laevis, Jamie L. Belrose

Legacy Theses & Dissertations (2009 - 2024)

Background: The South African claw-toed frog, Xenopus laevis, is uniquely suited for studying differences between regenerative and non-regenerative responses to CNS injury within the same organism, because some CNS neurons (e.g., retinal ganglion cells after optic nerve crush (ONC)) regenerate axons throughout life, whereas others (e.g., hindbrain neurons after spinal cord injury (SCI)) lose this capacity as tadpoles metamorphose into frogs. Tissues from these CNS regions (frog ONC eye, tadpole SCI hindbrain, frog SCI hindbrain) were used in a three-way RNA-seq study of axotomized CNS axons to identify potential core gene expression programs for successful CNS axon regeneration.

The Relationship Between Group Identification And Perceived Control Under Stressful Conditions, Fanshu Jin

Legacy Theses & Dissertations (2009 - 2024)

Group identification provides important psychological resources. One potential benefit is that it may relieve individuals’ strain in stressful situation by increasing their perceived personal control. The current research explores the different roles that group identification plays in reaction to stressful performance situations. In particular, it investigates the extent to which group identification impacts perceived control in performance contexts. It was hypothesized that activating group identification prior to performing a challenging task will bolster perceptions of personal control, thereby sustaining or improving performance. An experimental study was conducted that manipulated salience of group identification, either before or after exposure to a …

Missing In Action: Locating The Body In Interdisciplinary Studies, Ann Lenore Moradian

Master's Theses

This research project relied on the use of interdisciplinary literature, surveys and interviews to explore the prevalence of the human body and its movement across a variety of disciplines other than movement-based practices, and also to explore perspectives of movement experts regarding the knowledge, skills, and capacities they believed might be related to their practice-based work. In other words, what do movement practitioners and movement experts know, and who cares? The materials gathered were analyzed with the aim of understanding the range of possibilities for future work, and identifying areas of potential discourse, engagement, or collaboration across disciplines. The outcomes …

Low-Intensity Vibration Restores Nuclear Yap Levels And Acute Yap Nuclear Shuttling In Mesenchymal Stem Cells Subjected To Simulated Microgravity, Matthew Thompson, Kali Woods, Joshua Newberg, Julia Thom Oxford, Gunes Uzer

Mechanical and Biomedical Engineering Faculty Publications and Presentations

Reducing the musculoskeletal deterioration that astronauts experience in microgravity requires countermeasures that can improve the effectiveness of otherwise rigorous and time-expensive exercise regimens in space. The ability of low-intensity vibrations (LIV) to activate force-responsive signaling pathways in cells suggests LIV as a potential countermeasure to improve cell responsiveness to subsequent mechanical challenge. Mechanoresponse of mesenchymal stem cells (MSC), which maintain bone-making osteoblasts, is in part controlled by the “mechanotransducer” protein YAP (Yes-associated protein), which is shuttled into the nucleus in response to cyto-mechanical forces. Here, using YAP nuclear shuttling as a measurement outcome, we tested the effect of 72 h …

Shedding Of Marburg Virus In Naturally Infected Egyptian Rousette Bats, South Africa, 2017, Janusz T. Pawęska, Nadia Storm, Wanda Markotter, Nicholas Di Paola, Michael R. Wiley, Gustavo Palacios, Petrus Jansen Van Vuren

University of Nebraska's National Strategic Research Institute: Publications

We detected Marburg virus RNA in rectal swab samples from Egyptian rousette bats in South Africa in 2017. This finding signifies that fecal contamination of natural bat habitats is a potential source of infection for humans. Identified genetic sequences are closely related to Ravn virus, implying wider distribution of Marburg virus in Africa.

The genus Marburgvirus, family Filoviridae, comprises 1 species, Marburg marburgvirus, which comprises 2 marburgviruses, Marburg virus (MARV) and Ravn virus (RAVV) (1). Marburgviruses cause sporadic but often fatal MARV disease in humans and nonhuman primates (2). The Egyptian rousette bat (Rousettus aegyptiacus) …

Positive Information Facilitates Response Inhibition In Older Adults Only When Emotion Is Task-Relevant, Samantha E Williams, Eric J Lenze, Jill D Waring

Open Access Publications

Emotional information is integral to everyday life and impacts a variety of cognitive abilities including response inhibition, a critical skill for maintaining appropriate and flexible behaviour. However, reported effects of emotion on response inhibition are inconsistent in younger adults, and very limited in older adults. Effects of aging are especially relevant because emotion regulation improves with aging despite declining inhibitory control over neutral information. Across three studies, we assessed the impact of emotional facial expressions on response inhibition in younger and older adults while manipulating attention to task stimuli. Emotional faces (versus neutral faces) altered response inhibition only when task …

Harvester Ants Reduce Seed Survivorship In Slickspot Peppergrass, A Rare Mustard Endemic To Idaho, Jennifer A. Brown, Ian C. Robertson

Biology Faculty Publications and Presentations

Seed predation can significantly reduce the reproductive success of individual plants and their populations. The consequences of seed predation often are most pronounced for rare plant species, in which loss of seeds can have a disproportionate effect on populations. The present study examined the effects of seed predation by Owyhee harvester ants (Pogonomyrmex salinus) on seed survivorship in slickspot peppergrass (Lepidium papilliferum), a rare mustard endemic to sagebrush-steppe habitat in southwestern Idaho. Within sagebrush-steppe, L. papilliferum is restricted to microsites known as “slick spots”—shallow depressions of soil characterized by distinct clay layers and surface water retention …

Naming The Cook Islands: Articulation Theory And ‘Akapapa‘Anga, Emma Ngakuraevaru Powell

Pacific Studies

The Cook Islands has existed as a formal polity for roughly one hundred years. There is no antecedent Māori name for this nation. Referencing the explorer Captain James Cook, it has been the nation’s primary identifier since the late nineteenth century despite the nation comprising fifteen islands and various and distinct cultural genealogies prior to European arrival. In this article, I ask how might we effectively describe the formation of the Cook Islands’ national identity and understand its name given its underlying genealogical and cultural diversity. In asking this question, I consider the utility of cultural studies’ articulation theory for …

Faculty Publications

Glucolipotocixity induces IL-1 β secretion which impairs pancreatic β-cell insulin secretion. Ellagic acid and urolithin A have strong anti-inflammatory effect on cells. Muscadine and amla are very good sources of ellagic acid. The present study examined the effect of ellagic acid, ellagic acid-rich muscadine or amla extract, or urolothin A on inflammation in β cells under glucolipotoxic conditions. Rat NIT-1 β cells were incubated in glucolipotoxic conditions (33.3 mM glucose, 250 μM palmitic acid or 33.3 mM glucose + 250 μM palmitic acid with or without ellagic acid, ellagic acid-rich muscadine or amla extracts standardized to its ellagic acid content, …

Implications Of Lysine Acetylation On The Enzymes Of The Tca Cycle, Sumana Venkat

Graduate Theses and Dissertations

The tricarboxylic acid (TCA) cycle is a central route for the energy production via oxidative phosphorylation and is ubiquitous throughout nature. Apart from playing a major role in energy provision, it is also essential for a wide range of physiological functions in any organism. Although an increasing emphasis is laid on the interlinking role of the cycle, its regulation and control are less very less understood. As the field progresses, the consequences of TCA cycle anomalies are shown to be tied to various cancers and other disorders. The matter becomes more complex when considering the varying functions of the isozymes …

The Use Of Inorganic And Organic Acids As Short Duration Antimicrobial Dips On Mitigating Pathogens Present On Commercial Chicken During Peri-Harvest, Dana Kristen Dittoe

Graduate Theses and Dissertations

With poultry being the most consumed meat in the United States, poultry processors must provide consumers with safe, wholesome products. As a consequence, poultry processors are faced with the challenge of reducing the presence of foodborne pathogens such as Salmonella spp. and Campylobacter jejuni among raw poultry products. Though multi-hurdle approaches using antimicrobials are placed throughout processing to reduce these pathogens, Salmonella and C. jejuni still persist among raw poultry. Thus, it was the objective of the current dissertation to investigate various antimicrobials, organic and inorganic acids, as short duration dips and sprays as means to reduce common pathogens (Salmonella, …

Organic Cation Transporter 3 And The Dopamine Transporter Differentially Regulate Catecholamine Uptake In The Basolateral Amygdala And Nucleus Accumbens, Katherine M. Holleran, Jamie H. Rose, Steven C. Fordahl, Kelsey C. Benton, Kayla E. Rohr, Paul J. Gasser, Sara R. Jones

Biomedical Sciences Faculty Research and Publications

Regional alterations in kinetics of catecholamine uptake are due in part to variations in clearance mechanisms. The rate of clearance is a critical determinant of the strength of catecholamine signaling. Catecholamine transmission in the nucleus accumbens core (NAcc) and basolateral amygdala (BLA) is of particular interest due to involvement of these regions in cognition and motivation. Previous work has shown that catecholamine clearance in the NAcc is largely mediated by the dopamine transporter (DAT), but clearance in the BLA is less DAT‐dependent. A growing body of literature suggests that organic cation transporter 3 (OCT3) also contributes to catecholamine clearance in …

No Longer, Not Yet: Retrofuture Hauntings On The Jetsons, Stefano Morello

Publications and Research

From Back to the Future to The Wonder Years, from Peggy Sue Got Married to The Stray Cats’ records – 1980s youth culture abounds with what Michael D. Dwyer has called “pop nostalgia,” a set of critical affective responses to representations of previous eras used to remake the present or to imagine corrective alternatives to it. Longings for the Fifties, Dwyer observes, were especially key to America’s self-fashioning during the Reagan era (2015).

Moving from these premises, I turn to anachronisms, aesthetic resonances, and intertextual references that point to, as Mark Fisher would have it, both a lost past …

History Uprooted: Georgia Applies Apportionment To Strict Liability Claims, Carey Sartain

Mercer Law Review

Adrienne Johns had experience riding motorcycles for over 20 years when in 2013, total failure of the front brake on his 2006 Suzuki GSX-R1000 caused him to hit a curb, throwing him from his bike and knocking him unconscious. The accident resulted in Johns being hospitalized for over two months following spinal fusion surgery and surgery to repair his hand. Subsequent to the accident, he discovered that there had been a recall notice from Suzuki related to his bike model’s front brake. At trial, Johns proved that a design defect in the front brake had ultimately caused the brake to …

Incidence Of Antibiotic Resistance And Plasmid Content In Freshwater Beach Sand And Water And Clinical Urinary Tract Infection Escherichia Coli Isolates, Robert F. White

Biology Theses

Antibiotic-resistant (AR) bacteria have been found in environmental ecosystems including beach sand and water, and pose a serious threat to the mitigation of human and animal disease. The presence of antibiotic residues in the environment, fueled by wastewater effluent and agricultural runoff, may produce selective pressure on introduced microbes such as Escherichia coli, leading to the production of AR populations. This study characterized and compared the antibiotic resistance patterns and plasmid content of E. coli isolated from a freshwater beach and clinical urinary tract infection (UTI) samples. A higher level of antibiotic resistance was expected in clinical (UTI) Escherichia coli …

Making It To The Phd: Gender And Student Performance In Sub-Saharan Africa, Monica Fisher, Violet Nyabaro, Ruth Mendum, Moses Osiru

All Peer-Reviewed Publications

Women's underrepresentation in science, technology, engineering, and mathematics (STEM) impedes progress in solving Africa's complex development problems. As in other regions, women's participation in STEM drops progressively moving up the education and career ladder, with women currently constituting 30% of Africa's STEM researchers. This study elucidates gender-based differences in PhD performance using new survey data from 227 alumni of STEM PhD programs in 17 African countries. We find that, compared to their male counterparts, sampled women had about one less paper accepted for publication during their doctoral studies and took about half a year longer to finish their PhD training. …

Shared Volatile Organic Compounds Between Camel Metabolic Products Elicits Strong Stomoxys Calcitrans Attraction, Merid Negash Getahun, Peter Ahuya, John Ngiela, Abel Orone, Daniel Masiga, Baldwyn Torto

All Peer-Reviewed Publications

The sources of animal odours are highly diverse, yet their ecological importance, in host–vector communication, remains unexplored. Here, using the camel (host)–Stomoxys calcitrans (vector) interaction, we collected and analyzed the Volatile Organic Compounds (VOCs) of camels from four of its different odour sources: breath, body (skin), urine, and dung. On non-metric model multivariate analyses of VOCs we show that substantial chemo-diversity exists between metabolic products associated with an individual camel. VOCs from the four metabolic products were distinct and widely segregated. Next, we show electrophysiologically, that VOCs shared between metabolic products activated more Olfactory Sensory Neurons (OSNs) and elicited strong …

The Effect Of In-Situ Activated Carbon On Biodegradation Of Tce, Sreedhar Harigovind

All Theses

Contaminants pose a serious concern due to their relative ease of transport through groundwater, where they can accumulate and become a plume (i.e. dissolved contaminants that move with groundwater flow). Chlorinated solvents are contaminants of concern due to their potential for causing cancer, organ disease, and other ailments. Due to improper storage and disposal, these solvents find themselves in groundwater reserves, and thus warrant the need for finding treatment options to remove them from the water. In-situ biodegradation of TCE is a respiratory process consisting of electron donors, acceptors, and microorganisms that are either native or introduced into the system. …
