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 …

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 Dec 2020

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 …

A Dogged Resolve: The Doctrine And Decline Of Mormon Plural Marriage, 1841-1890, Jaclyn Thornock Gadd Dec 2020

A Dogged Resolve: The Doctrine And Decline Of Mormon Plural Marriage, 1841-1890, Jaclyn Thornock Gadd

Graduate Masters Theses

A Dogged Resolve is an analytical micro-history of the theology and marital practices among members of The Church of Jesus Christ of Latter-day Saints from 1841 to 1890. In the spring of 1841, Joseph Smith, Church founder and leader, took another wife; an act which launched a long and controversial practice of polygamy by a small minority within the community. After the Latter-day Saints migrated west, the isolation of the Rocky Mountains fostered a period where plural families could thrive and the first generation endeavored to establish marital norms. However, with advancements in technology and transportation, the younger generations adopted …

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 …


Stability Of Group Four Monochalcogenides In Water And Air, William Shattuck Dec 2020

Stability Of Group Four Monochalcogenides In Water And Air, William Shattuck

Graduate Theses and Dissertations

Previously published works have simulated the behavior of monolayer group IV monochalcogenides and predicted them to have very useful electronic properties. These simulations have also predicted that monolayers of group IV monochalcogenides will degrade quickly when exposed to water, even in extremely low concentrations. We hypothesize that thin samples of these materials will show signs of degradation if left in air and in water for an extended period of time.

Samples of each of the four monochalcogenides (GeS, GeSe, SnS and SnSe) were exfoliated onto clean oxidized silicon substrates. Chemical analysis showed the SnSe samples were contaminated, so they were …

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, …


Design Of Hfgf1 Variant(S) With Increased Stability And Enhanced Bioactivity, Shilpi P. Agrawal Dec 2020

Design Of Hfgf1 Variant(S) With Increased Stability And Enhanced Bioactivity, Shilpi P. Agrawal

Graduate Theses and Dissertations

Fibroblast growth factors (FGFs) are involved in various cellular processes such as cell growth,proliferation, differentiation, migration, angiogenesis, wound healing and embryonic development. Human acidic fibroblast growth factor (hFGF1) binds non-selectively to all the four FGF-receptors and is therefore considered as a powerful mitogen with broadest specificity. However, pharmacological applications of hFGF1 are restricted due to the low thermal stability of the growth factor. hFGF1 has low thermodynamic stability under physiological temperatures which leads to impairment of cellular signaling process thereby preventing its potential mitogenic properties. hFGF1 has a heparin binding pocket at the C-terminus which comprises of positively charges residues. …


Disordered Eating Among Nonbinary Individuals, Marilyn Chung Dec 2020

Disordered Eating Among Nonbinary Individuals, Marilyn Chung

Dissertations

Research on influences of eating disorders have informed diagnosis and treatment of eating disorders, particularly for White cisgender women. A Perfect Biopsychosocial Storm is a theory of influences of disordered eating development: sociocultural influences of rigid body shape and size ideals, high rates of trauma and violence, experiences of objectification and sexualization, and biological changes (Maine & Bunnell, 2010). For transgender individuals, recent findings suggest disparities and negative mental health outcomes such as elevated prevalence of disordered eating, body image concerns, and self-reported disordered eating. For transgender men and women, researchers found that disordered eating may be related to attempts …

Dynamic Dissolved Organic Matter Response To Increases Of Energy Availability In Forested Headwater Streams, Katherine Xiomara Perez-Rivera Dec 2020

Dynamic Dissolved Organic Matter Response To Increases Of Energy Availability In Forested Headwater Streams, Katherine Xiomara Perez-Rivera

Master's Theses and Capstones

Forested headwater streams receive inputs of dissolved organic matter (DOM) that can be transformed by biota as they are transported downstream. Biotic uptake of ambient DOM is difficult to assess through direct experimentation, as the fate of a specific organic compound added to a stream is unlikely to mirror that of the ambient DOM pool. Here we examined the dynamics of DOM by using a hybrid approach that combines uptake metrics of a simple organic compound with a direct assessment of the effects of adding this presumably labile organic carbon source (acetate) on the ambient DOM pool. We proposed that …
