Faculty and Student Publications

This study aimed to explore the phytoconstituents of Agonis flexuosa, F. Myrtaceae and its biological activity. A thorough phytochemical investigation of its leaves led to the isolation of one new stilbene glycoside; (Z)-2,3-dihydroxystilbene-5-O-β-D-glucoside (1), and fifteen known compounds identified as two stilbenes: (Z)-pinosylvin mono methyl ether (2) and (Z)-pinosylvin-3-O-β-D-glucoside (3); six flavanones: (2S)-pinostrobin (4), (2S)-strobopinin (5), (2S)-cryptostobin (6), (2S)-pinocembrin (7), (2S)-dimethylpinocembrin (8) and (2S)-dimethylstrobopinin (9); four flavonoids: quercetin (10), kaempferol-7-O-β-D-glucoside (11), quercetin-3-O-α-D-rhamnoside (12) and quercetin-3-O-β-D-glucoside (13), α-terpineol (14), β-sitosterol (15) and gallic acid (16). The structures of the isolated metabolites were elucidated based upon the interpretation of their 1D and …

Comparative Performance Of Reduced-Risk Fungicides And Biorational Products In Management Of Postharvest Botrytis Blight On Bigleaf Hydrangea Cut Flowers, Ravi Bika, Cristi Palmer, Lisa Alexander, Fulya Baysal-Gurel

Agricultural and Environmental Sciences Faculty Research

Botrytis cinerea is one of the problematic and notorious postharvest pathogens of bigleaf hydrangea (Hydrangea macrophylla) cut flowers. It causes flower blight, leaf blight, and stem rot, reducing the ornamental value (such as longevity, color, and texture) of flowers, ultimately making them unsalable. The objective of this study was to identify effective conventional fungicides and biorational products for botrytis blight management on bigleaf hydrangea cut flowers that can be easily and readily adopted by growers of ornamentals. Preventive preharvest whole-plant spray and postharvest dip treatment applications were used in this study. For the whole-plant spray applications, bigleaf hydrangea …

A Mendelian Randomization Study Of Telomere Length And Blood-Cell Traits, Charleen D. Adams, Brian B. Boutwell

Faculty and Student Publications

© 2020, The Author(s). Whether telomere attrition reducing proliferative reserve in blood-cell progenitors is causal has important public-health implications. Mendelian randomization (MR) is an analytic technique using germline genetic variants as instrumental variables. If certain assumptions are met, estimates from MR should be free from most environmental sources of confounding and reverse causation. Here, two-sample MR is performed to test whether longer telomeres cause changes to hematological traits. Summary statistics for genetic variants strongly associated with telomere length were extracted from a genome-wide association (GWA) study for telomere length in individuals of European ancestry (n = 9190) and from GWA …

From International Borders To The Honeycombing Of Internal Borders: Response To Covid-19 Pandemic, David E. Toohey

International Journal of Peace Studies

This article looks at borders during the Covid-19 crisis. In particular, it looks at how internal borders have arisen following xenophobic and national responses to Covid-19. This rise of internal borders is referred to as the honeycombing of borders. This article takes a genealogical approach to understand how borders have arisen—despite not always favorable opinions about them. Therefore, this looks at Rancière’s (1999; 2004) concept of the “police order” in the imposition of the sensible through Foucault’s genealogical approach, both to show the temporary, haphazard nature of these borders and how they revert to less desirable things. This is situated …

Nutrition Faculty Publications

Within the away-from-home food environment there is a need to account for individual exposure (e.g., frequency of visitation) to that environment. The present study examined the consumer environment in both proximal and visited restaurants and their association with childrens’ diet quality and anthropometrics. A cross-sectional analysis used baseline data from the Neighborhood Impact on Kids (NIK) study (2007–2009). Participants were 6–12-year-olds living in King County, WA and San Diego County, CA. This analysis (conducted 2019–2020) examined relationships between nearby restaurant count, Nutrition Environment Measures Survey in Restaurants (NEMS-R) within the child’s block group, and weighted NEMS-R scores based on the …

Legal Terms Of Use And Public Genealogy Websites, Jorge L. Contreras, Kyle Schultz, Craig Teerlink, Tim Maness, Laurence Meyer, Lisa Cannon-Albright

Utah Law Faculty Scholarship

Public genealogy websites, to which individuals upload family history, genealogy, and sometimes individual genetic data, have been used in an increasing number of public health, epidemiological, and genetic studies. Yet there is little awareness among researchers of the legal rules that govern the use of these online resources. We analyzed the online Terms of Use (TOU) applicable to 17 popular genealogy websites and found that none of them expressly permit scientific research, while at least 13 contain restrictions that may limit or prohibit scientific research using data obtained from those sites. In order to ensure that researchers who use genealogy …

Delimiting Cryptic Morphological Variation Among Human Malaria Vector Species Using Convolutional Neural Networks, Jannelle Couret, Danilo C. Moreira, Davin Bernier, Aria Mia Mia Loberti, Ellen M. Dotson, Marco Alvarez

Computer Science and Statistics Faculty Publications

Deep learning is a powerful approach for distinguishing classes of images, and there is a growing interest in applying these methods to delimit species, particularly in the identification of mosquito vectors. Visual identification of mosquito species is the foundation of mosquito-borne disease surveillance and management, but can be hindered by cryptic morphological variation in mosquito vector species complexes such as the malaria-transmitting Anopheles gambiae complex. We sought to apply Convolutional Neural Networks (CNNs) to images of mosquitoes as a proof-of-concept to determine the feasibility of automatic classification of mosquito sex, genus, species, and strains using whole-body, 2D images of mosquitoes. …

Degradation Of Mind Oscillator Complexes By Escherichia Coli Clpxp, Christopher J. Labreck, Catherine E. Trebino, Colby N. Ferreira, Josiah Morrison, Eric C. Dibiasio, Joseph Conti, Jodi L. Camberg

Cell and Molecular Biology Faculty Publications

MinD is a cell division ATPase in Escherichia coli that os- cillates from pole to pole and regulates the spatial position of the cell division machinery. Together with MinC and MinE, the Min system restricts assembly of the FtsZ-ring to midcell, oscillating between the opposite ends of the cell and preventing FtsZ-ring misassembly at the poles. Here, we show that the ATP-dependent bacterial proteasome complex ClpXP degrades MinD in reconstituted degradation reactions in vitro and in vivo through direct recognition of the MinD N-terminal region. MinD degradation is enhanced during stationary phase, suggesting that ClpXP regulates levels of MinD in …

A Library Of Low Molecular Weight Fluorescent Probes For The Detection Of Cu(Ii) And Fe(Iii) Ions, Ashley Johnson

Dissertations

This dissertation reports the synthesis and photophysical properties of a family of rhodamine dyes (compounds 3.9-3.13 and 4.6). The rhodamine dyes are prepared in two steps, and fully characterized by ESI-MS (Low and High resolution), X-Ray crystallography, NMR spectroscopy, and FT-IR spectroscopy. The coordination environment of the low molecular weight fluorescent probes (LMFPs) was systematically changed to investigate the thermodynamic behavior between the LMFPs and an array of metal ions (Cu²⁺, Fe²⁺, and Hg²⁺ ions) in protic and aprotic solvent systems. Upon coordinating to metal ions, the π-conjugation of the LMFPs changed, resulting in …

A Focus Group Study Of Adult American Males On Hemodialysis As Captured Through Photovoice, Donna Sanders

Dissertations

Chronic diseases pose a significant burden on the United States (U.S.) healthcare system (Centers for Medicare & Medicaid Services [CMS], 2019). The Center for Disease Control and Prevention (CDC) projects that chronic diseases will affect an estimated 164 million Americans by the year 2025, which accounts for approximately half of the nation’s population (CDC, 2017). Nearly 90% of the nation’s $3.5 trillion in annual healthcare expenditures are for individuals with chronic and mental health conditions (Buttorff et al., 2017; CMS, 2017).

The purpose of this qualitative study was to investigate the lived experiences of adult African American males on hemodialysis …

Hemodynamic Response During Sedentary Behavior In Black/African American And White Males, Raymond Jones

Dissertations

Emerging evidence suggests that uninterrupted sitting has a deleterious impact on hemodynamics, namely a reduction in blood-flow induced shear stress in peripheral vessels, which leads to vascular dysfunction and increased arterial stiffness. Few studies have examined the cerebrovascular response, and no studies have discerned potential racial differences on the hemodynamic response to uninterrupted sitting. Purpose: To examine racial differences in the hemodynamic response during an acute period (1-hour) of uninterrupted sitting between Black/African American and White males. Methods: Twenty-four adult males (50% Black/African American) between the ages of 18 and 35 years and relatively healthy (i.e., free of …

Transformers: The Relationship Between Instructor And Course Persistence Among Community College Students, Jairus L. Johnson

Dissertations

U.S. community colleges play a unique role in providing higher education opportunities for members of society and are often viewed as the gateway to a post-secondary education (Savi, 2011). Two-year colleges foster a robust mission that is supported by a variety of curricular functions that tailor to a diverse student population. Furthermore, through an open-door policy, admittance only requires a high school diploma or equivalent. The aforementioned factors have created inherent challenges associated with student persistence, institutional retention, program completion, and graduation rates among community colleges. As compared to universities, community colleges have lower graduation and retention rates.

An Examination Of The Influence Of Multi-Scale Processes And Connectivity On The Population And Assemblage Dynamics Of Headwater Fishes, Josh P. Hubbell

Dissertations

Typified by their branching pattern, headwaters are numerically abundant as the density of these habitats increases with increasing distance from the base of a dendritic river system. Connectivity among headwaters is complex, resulting in the spatial isolation of populations. Headwater specialists have evolved a suite of traits that permit these species to permanently reside within these habitats. The spatial configuration and connectivity of headwaters has repercussions for metapopulations and meta-assemblages. I investigated how multi-scale processes and connectivity influenced the patch occupancy, coexistence, movement ecology, population structure, and gene flow of headwater specialists. In chapter two, I used occupancy modeling to …

Plasma iGH was measured pre-exercise, immediately-post …

Productivity Loss Associated With Functional Disability In A Contemporary Small-Scale Subsistence Population, Jonathan Stieglitz, Paul L. Hooper, Benjamin C. Trumble, Hillard Kaplan, Michael D. Gurven

ESI Publications

In comparative cross-species perspective, humans experience unique physical impairments with potentially large consequences. Quantifying the burden of impairment in subsistence populations is critical for understanding selection pressures underlying strategies that minimize risk of production deficits. We examine among forager-horticulturalists whether compromised bone strength (indicated by fracture and lower bone mineral density, BMD) is associated with subsistence task cessation. We also estimate the magnitude of productivity losses associated with compromised bone strength. Fracture is associated with cessation of hunting, tree chopping, and walking long distances, but not tool manufacture. Age-specific productivity losses from hunting cessation associated with fracture and lower BMD …

Just-In-Time Teaching Adds Motivation But Is Less Efficient, Vladik Kreinovich, Olga Kosheleva, Christian Servin

Departmental Technical Reports (CS)

For each major, in addition to directly major-related topics, students also need to learn auxiliary topics –- e.g., math topics –- which are needed to understand more direct major-related ones. To learn these auxiliary topics, students are required to take some prerequisite math class. The problem is that when the students take these classes, they do not fully understand how these classes are related to their major. As a result, they often lack motivations, do not study well, and this hinders their performance in the follow-up major-related classes. One way to enhance the students' motivation is to use just-in-time teaching, …

The Circadian Clock—A Molecular Tool For Survival In Cyanobacteria, Pyonghwa Kim, Manpreet Kaur, Hye-In Jang, Yongick Kim

Chemistry Faculty Research

Cyanobacteria are photosynthetic organisms that are known to be responsible for oxygenating Earth’s early atmosphere. Having evolved to ensure optimal survival in the periodic light/dark cycle on this planet, their genetic codes are packed with various tools, including a sophisticated biological timekeeping system. Among the cyanobacteria is Synechococcus elongatus PCC 7942, the simplest clock-harboring organism with a powerful genetic tool that enabled the identification of its intricate timekeeping mechanism. The three central oscillator proteins—KaiA, KaiB, and KaiC—drive the 24 h cyclic gene expression rhythm of cyanobacteria, and the “ticking” of the oscillator can be reconstituted inside a test tube just …
