The Price Of Surviving On Adrenaline: Developmental Programming Responses To Chronic Fetal Hypercatecholaminemia Contribute To Poor Muscle Growth Capacity And Metabolic Dysfunction In Iugr-Born Offspring, Rachel L. Gibbs, Dustin T. Yates Dec 2021

The Price Of Surviving On Adrenaline: Developmental Programming Responses To Chronic Fetal Hypercatecholaminemia Contribute To Poor Muscle Growth Capacity And Metabolic Dysfunction In Iugr-Born Offspring, Rachel L. Gibbs, Dustin T. Yates

Department of Animal Science: Faculty Publications

Maternofetal stress induces fetal programming that restricts skeletal muscle growth capacity and metabolic function, resulting in intrauterine growth restriction (IUGR) of the fetus. This thrifty phenotype aids fetal survival but also yields reduced muscle mass and metabolic dysfunction after birth. Consequently, IUGR-born individuals are at greater lifelong risk for metabolic disorders that reduce quality of life. In livestock, IUGR-born animals exhibit poor growth efficiency and body composition, making these animals more costly and less valuable. Specifically, IUGR-associated programming causes a greater propensity for fat deposition and a reduced capacity for muscle accretion. This, combined with metabolic inefficiency, means that these …

Element Contamination In Port Everglades – Preparing For Ecological Impacts, Laura White

All HCAS Student Capstones, Theses, and Dissertations

Port dredging is of economic importance worldwide but its impacts to the marine environment through the remobilization of elemental contaminants are not well understood. A massive deepening and widening of Port Everglades, Florida, will begin in 2023. Contaminated sediment disturbed during the dredging process could be released and prove to be harmful to three coral reef tracks located beginning 1.5 miles away from the port. This study focused on identifying and quantifying 14 different trace elements: arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), mercury (Hg), lead (Pb), manganese (Mn), molybdenum (Mo), nickel (Ni), selenium (Se), tin (Sn), …

Atherosclerosis is a lipid-driven chronic inflammatory disease that leads to the formation of plaques in the inner lining of arteries. Plaques form over a range of phenotypes, the most severe of which is vulnerable to rupture and causes most of the clinically significant events. In this study, we evaluated the efficacy of nanoparticles (NPs) to differentiate between two plaque phenotypes based on accumulation kinetics in a mouse model of atherosclerosis. This model uses a perivascular cuff to induce two regions of disturbed wall shear stress (WSS) on the inner lining of the instrumented artery, low (upstream) and multidirectional (downstream), which, …

The Scoop On Composting: A Comprehensive Literature Review On Composting With A Focus On Grand Valley State University, Alexandria Snabes Dec 2021

The Scoop On Composting: A Comprehensive Literature Review On Composting With A Focus On Grand Valley State University, Alexandria Snabes

Honors Projects

This comprehensive review discusses the main microbial processes, methods, efficiency strategies, benefits, and drawbacks related to composting. Specifically, anaerobic, aerobic, and intermediate, or cold composting, decomposition processes are defined and assessed. This leads into a discussion of some common methods of composting, both large- and small-scale, which utilize these microbial processes to result in differing advantages and disadvantages. The efficiency of these methods can be increased using strategies that monitor oxygen levels, moisture levels, temperate levels, and overall size. Some benefits of composting discussed include diverting waste from landfills, improving soil nutrition and quality long-term, and increasing plant growth and …

Functional Differentiation In The Language Network Revealed By Lesion-Dymptom Mapping, William Matchin, Alexandra Basilakos, Dirk B. Den Ouden, Brielle C. Stark, Gregory Hickok, Julius Fridriksson Dec 2021

Functional Differentiation In The Language Network Revealed By Lesion-Dymptom Mapping, William Matchin, Alexandra Basilakos, Dirk B. Den Ouden, Brielle C. Stark, Gregory Hickok, Julius Fridriksson

Communication Sciences and Disorders Faculty Articles and Research

Theories of language organization in the brain commonly posit that different regions underlie distinct linguistic mechanisms. However, such theories have been criticized on the grounds that many neuroimaging studies of language processing find similar effects across regions. Moreover, condition by region interaction effects, which provide the strongest evidence of functional differentiation between regions, have rarely been offered in support of these theories. Here we address this by using lesion-symptom mapping in three large, partially-overlapping groups of aphasia patients with left hemisphere brain damage due to stroke (N = 121, N = 92, N = 218). We identified multiple measure by …

Exploring The Impact Of Social Influence Mechanisms And Network Density On Societal Polarization, Justin Mittereder Dec 2021

Exploring The Impact Of Social Influence Mechanisms And Network Density On Societal Polarization, Justin Mittereder

Departmental Honors & Graduate Capstone Projects

I present an agent-based model, inspired by the opinion dynamics
(OD) literature, to explore the underlying behaviors that may induce
societal polarization. My agents interact on a social network, in which
adjacent nodes can influence each other, and each agent holds an array
of continuous opinion values (on a 0-1 scale) on a number of separate
issues. I use three measures as a proxy for the virtual society’s “po-
larization:” the average assortativity of the graph with respect to the
agents’ opinions, the number of non-uniform issues, and the number
of distinct opinion buckets in which agents have the same …

Enhancing Situational Awareness For Rotorcraft Pilots Using Virtual And Augmented Reality, Ardit Pranvoku Dec 2021

Enhancing Situational Awareness For Rotorcraft Pilots Using Virtual And Augmented Reality, Ardit Pranvoku

Theses and Dissertations

Rotorcraft pilots often face the challenge of processing a multitude of data, integrating it with prior experience and making informed decisions in complex, rapidly changing multisensory environments. Virtual Reality (VR), and more recently Augmented Reality (AR) technologies have been applied for providing users with immersive, interactive and navigable experiences. The research work described in this thesis demonstrates that VR/AR are particularly effective in providing real-time information without detracting from the pilot's mission in both civilian and military engagements. The immersion of the pilot inside of the VR model provides enhanced realism. Interaction with the VR environment allows pilots to practice …

C. S. Lewis And His Later Respondents: Letting In Fresh Air, Preventing Questions, And Reimagining A Preface To Paradise Lost, David V. Urban Dec 2021

C. S. Lewis And His Later Respondents: Letting In Fresh Air, Preventing Questions, And Reimagining A Preface To Paradise Lost, David V. Urban

University Faculty Publications and Creative Works

This essay chronicles significant responses to C. S. Lewis’s A Preface to Paradise Lost (1942) that occurred from the 1960s into the twenty-first century. Important responses include those of William Empson, Stanley Fish, Stuart Curran, John Rumrich, Peter C. Herman, Michael Bryson, and Joseph Wittreich. All of these scholars challenged Lewis on various points—most commonly concerning matters of Lewis’s analysis of Milton’s Satan, his alleged oversimplification of Milton’s theologically complex epic, the supposed similarities between A Preface and Fish’s Surprised by Sin, and his assumed hegemonic prevention of new avenues of critical inquiry into Milton’s epic. This essay contends …

Evidence Of Myomir Regulation Of The Pentose Phosphate Pathway During Mechanical Load-Induced Hypertrophy, Taylor Valentino, Vandre C. Figueiredo, C. Brooks Mobley, John J. Mccarthy, Ivan J. Vechetti Jr.

Physiology Faculty Publications

Many of the molecular and cellular mechanisms discovered to regulate skeletal muscle hypertrophy were first identified using the rodent synergist ablation model. This model reveals the intrinsic capability and necessary pathways of skeletal muscle growth in response to mechanical overload (MOV). Reminiscent of the rapid cellular growth observed with cancer, we hypothesized that in response to MOV, skeletal muscle would undergo metabolic programming to sustain increased demands to support hypertrophy. To test this hypothesis, we analyzed the gene expression of specific metabolic pathways taken from transcriptomic microarray data of a MOV time course. We found an upregulation of genes involved …

Future rice systems must produce more grain while minimizing the negative environmental impacts. A key question is how to orient agricultural research & development (R&D) programs at national to global scales to maximize the return on investment. Here we assess yield gap and resource-use efficiency (including water, pesticides, nitrogen, labor, energy, and associated global warming potential) across 32 rice cropping systems covering half of global rice harvested area. We show that achieving high yields and high resource-use efficiencies are not conflicting goals. Most cropping systems have room for increasing yield, resource-use efficiency, or both. In aggregate, current total rice production …

Faculty Publications

Anorexia nervosa (AN) is characterised by disrupted and restrictive eating patterns. Recent investigations and meta-analyses have found altered concentrations of inflammatory markers in people with current AN. We aimed to assess nutrient intake in participants with current or recovered AN, as compared to healthy individuals, and explore group differences in dietary inflammatory potential as a possible explanation for the observed alterations in inflammatory markers. We recruited participants with current AN (n = 51), those recovered from AN (n = 23), and healthy controls (n = 49). We used the Food Frequency Questionnaire (FFQ), to calculate a Dietary …

Spatiotemporal Variation Of An Eastern Tropical Pacific Pelagic Community Assessed With Free-Drifting Bruvs, Tyler Stephen Plum Dec 2021

Spatiotemporal Variation Of An Eastern Tropical Pacific Pelagic Community Assessed With Free-Drifting Bruvs, Tyler Stephen Plum

All HCAS Student Capstones, Theses, and Dissertations

Information about pelagic community diversity and ecology generally lags far behind that of coastal communities, and largely derives from fisheries data that do not reflect small and non-target species. We describe spatiotemporal vertebrate species diversity and variability over a 3,486 km2 area of highly productive pelagic marine ecosystem in Pacific Panama using drifting baited remote underwater video stations (BRUVS), a non-invasive fishery-independent sampling technique. We observed 26 taxa from 17 families, including 1 mammal, 3 reptile, 5 elasmobranch, and 17 teleost species. Community assemblages differed on and off the continental shelf and between wet (April – December) and dry …

Elevated serum urate levels, a complex trait and major risk factor for incident gout, are correlated with cardiometabolic traits via incompletely understood mechanisms. DNA methylation in whole blood captures genetic and environmental influences and is assessed in transethnic meta-analysis of epigenome-wide association studies (EWAS) of serum urate (discovery, n = 12,474, replication, n = 5522). The 100 replicated, epigenome-wide significant (p < 1.1E-7) CpGs explain 11.6% of the serum urate variance. At SLC2A9, the serum urate locus with the largest effect in genome-wide association studies (GWAS), five CpGs are associated with SLC2A9 gene expression. Four CpGs at SLC2A9 have significant causal effects on serum urate levels and/or gout, and two of these partly mediate the effects of urate-associated GWAS variants. In other genes, including SLC7A11 and PHGDH, 17 urate-associated CpGs are associated with conditions defining metabolic syndrome, suggesting that these CpGs may represent a blood DNA methylation signature of cardiometabolic risk factors. This study demonstrates that EWAS can provide new insights into GWAS loci and the correlation of serum urate with other complex traits.

Open Access Publications

Hedgehog (HH) morphogen signalling, crucial for cell growth and tissue patterning in animals, is initiated by the binding of dually lipidated HH ligands to cell surface receptors. Hedgehog-Interacting Protein (HHIP), the only reported secreted inhibitor of Sonic Hedgehog (SHH) signalling, binds directly to SHH with high nanomolar affinity, sequestering SHH. Here, we report the structure of the HHIP N-terminal domain (HHIP-N) in complex with a glycosaminoglycan (GAG). HHIP-N displays a unique bipartite fold with a GAG-binding domain alongside a Cysteine Rich Domain (CRD). We show that HHIP-N is required to convey full HHIP inhibitory function, likely by interacting with the …

Open Access Publications

During ontogeny, macrophage populations emerge in the Yolk Sac (YS) via two distinct progenitor waves, prior to hematopoietic stem cell development. Macrophage progenitors from the primitive/"early EMP" and transient-definitive/"late EMP" waves both contribute to various resident primitive macrophage populations in the developing embryonic organs. Identifying factors that modulates early stages of macrophage progenitor development may lead to a better understanding of defective function of specific resident macrophage subsets. Here we show that YS primitive macrophage progenitors express Lyl-1, a bHLH transcription factor related to SCL/Tal-1. Transcriptomic analysis of YS macrophage progenitors indicate that primitive macrophage progenitors present at embryonic day …

Investigating The Influence Of Available Drinking Water On Wildlife In Utah's West Desert, Danielle K. Finlayson Dec 2021

Investigating The Influence Of Available Drinking Water On Wildlife In Utah's West Desert, Danielle K. Finlayson

Theses and Dissertations

The availability of water is a limiting resource for many wildlife species in arid and semi- arid environments. Free water is essential for critical life stages for numerous species, including migration, reproduction, survival, and habitat selection. Riparian areas in the desert occur relatively infrequently, but support a disproportionally large percentage of plant and wildlife species found in arid environments. Our study covered two aspects of water use in the west desert of Utah. The first was assessing the impacts of nonnative ungulates (specifically feral horses and cattle) on natural springs, and how they influenced water quality, vegetation, and wildlife diversity …

An Assessment Of The Diverse Freshwater Turtle Fauna Of Mississippi, Lucas Haralson Dec 2021

An Assessment Of The Diverse Freshwater Turtle Fauna Of Mississippi, Lucas Haralson

Master's Theses

Nestled within the Southeastern United States Turtle Priority Area, Mississippi boasts impressive freshwater turtle diversity and is home to 8.6% of extant turtle species. Despite this impressive richness, few studies have assessed freshwater turtle assemblages in this hotspot of aquatic diversity. This research aimed to elucidate the distributions and abundances of freshwater turtle species through a statewide investigation of all major river drainages of the state. Using baited hoop nets (90 cm and 120 cm diameter), turtles were collected, identified to species and sex, and measured, before being released. Turtle assemblages were assessed in both lotic and lentic environments from …

Artifact, Durotimi A. Akinkugbe

Theses

Artifact is a 3D animated short film following the journey of a mysterious metal, altered by time and human interaction across several millennia. The titular artifact first arrives on a barren prehistoric Earth as the remains of a meteorite impact, a rock glistening with metallic ore. The epoch passes as the natural world comes to life, vegetation growing at the site of the crater. The ore-rock, having remained untouched all these years, is finally found by an early human. It is attached to a stick, forming a primitive hammer. After some use, the hammer breaks, and the ore is smelted, …

Aquaporin Expression And Cholesterol Content In Eel Swimbladder Tissue, Victoria Drechsel, Gabriel Schneebauer, Birgit Fiechtner, Christopher P. Cutler, Bernd Pelster

Biology: Faculty Publications

Leakiness of the swimbladder wall of teleost fishes must be prevented to avoid diffusional loss of gases out of the swimbladder. Guanine incrustation as well as high concentrations of cholesterol in swimbladder membranes in midwater and deep-sea fish has been connected to a reduced gas permeability of the swimbladder wall. On the contrary, the swimbladder is filled by diffusion of gases, mainly oxygen and CO2, from the blood and the gas gland cells into the swimbladder lumen. In swimbladder tissue of the zebrafish and the Japanese eel, aquaporin mRNA has been detected, and the aquaporin protein has been considered important …

Spring Regrowth And Steer Performance On Tifton 85 And Coastal Bermudagrass Pastures Following Sod-Seeding With Ryegrass, G. M. Hill, R. N. Gates Dec 2021

Spring Regrowth And Steer Performance On Tifton 85 And Coastal Bermudagrass Pastures Following Sod-Seeding With Ryegrass, G. M. Hill, R. N. Gates

IGC Proceedings (1977-2023)

Effects of autumn sod-seeded ryegrass (Lolium multiflorum; cv. Passerel; 37.7 kg/ha) in bermudagrass pastures (Cynodon spp.; cv. Coastal and cv. Tifton 85) on grazing steer performance were determined. Ryegrass was sod-seeded in three of six .81 ha pastures of each bermudagrass. Forage height was adjusted to10 cm during spring. Stocking rates were unaffected by ryegrass in Tifton 85 pastures, but they were higher (P < .05) for Tifton 85 than Coastal. Ryegrass increased tester steer average daily gains by 34% (.86 vs .64 kg/day; P < .01), and gain/ha by 26% (387 vs 306 kg/ha; P < .05). Higher stocking rates resulted in 22% more grazing days (515 vs 421 days/ha; P < .01), and 30% higher gain/ha (391 vs 301 kg/ha; P < .05) for Tifton 85 than Coastal pastures. Ryegrass did not affect stocking rates or steer performance on Tifton 85, but it depressed both on Coastal pastures.

Intensive Grazing Systems For Beef Cattle Production, F. P. Fontenot, V. G. Allen, M. A. Cochran, N. B. Frank

IGC Proceedings (1977-2023)

The objective of this study was to compare grazing systems that used rotational and continuous stocking for beef cows-calves and stocker cattle grazing fescue (Festuca arundinacea) and clover (Trifolium repens). For each system seven cows/calves and seven stocker steers were used within each of two replicates. The cows and stockers grazed stockpiled forage and were fed hay in winter, and grazed growing forage during spring and summer. Cows in the rotational system gained at a faster rate (P< . 05) from October to April than those in the continuous system. Daily gains of calves were higher (P< . 05) for the continuous system. Rate of gain during the last 28 days was higher (P< . 05) for the stockers in the rotational system. Average hay yields were not different for the two stocking systems, but more (P< . 05) hay was fed to the cattle in the continuous system. The system that used continuous stocking was more easily managed and required less labor and facilities.
