Photobiomodulation Of Bovine Oocytes During Maturation Increases Atp Content And Enhances Subsequent Embryonic Development, Kendall Richey

All Theses

Bovine in-vitro production(IVP) of embryos is a growing field for producing offspring with desirable genetics in the cattle industries. While IVP is effective, oocyte cytoplasmic maturation is compromised, and bovine oocytes matured in-vitro have reduced metabolic activity than those matured in-vivo. Mitochondria are the central unit of oocyte metabolism, producing ATP through OXPHOS. Photobiomodulation is a light treatment reported to improve metabolic activity. In five experiments, we measured the effects of photobiomodulation treatment with red LED at 16-(L-16) and 20 h(L-20) of bovine oocyte in-vitro maturation on subsequent embryonic development, mitochondrial activity and nuclear progression. Bovine COCs were aspirated …

An In Vitro Investigation Of Urothelial Cell Function In Response To Hypoxia And Pressure In Relation To Bladder Outlet Obstruction, Britney Hudson

All Dissertations

Bladder outlet obstruction (BOO) is a prevalent urological condition and can be characterized by the presence of lower urinary tract symptoms (LUTS), such as hesitancy, weak stream, and nocturia. The main cause of BOO is a partial blockage of the urethra, which results in elevated voiding pressure, high storage pressure, and tissue ischemia, which are thought to be the triggers of bladder inflammation and subsequent fibrosis. Often patients do not seek treatment until the conditions get severe. Thus, it would be ideal to have an early diagnostic tool to detect changes in the bladder due to BOO. Extracellular vesicles (EVs) …

Toxicokinetics And Toxicodynamics Of Radium-226 In An Estuarine Sentinel Species Geukensia Demissa, Sarah Donaher

All Dissertations

The historical use of radioluminescent objects, most notably those containing radium-226 (²²⁶Ra)-based paint, has contributed to contemporary environmental contamination of radioactive material, often near naval installations or other military-associated coastal sites. The risk to both human and environmental health from this small-scale, discrete radioactive material is challenging to predict due to large uncertainties in the source terms, bioavailability, and toxicity of these objects. The objective of this study was to provide information on the accumulation and toxicity of acute ²²⁶Ra exposure in a sentinel species to improve risk assessments for small-scale, coastal radiological contamination. The sentinel species …

A Rhetorical-Sociological Understanding Of Emotion, Amy Boone

All Dissertations

This project presents a rhetorical-sociological understanding of emotion while foregrounding the place and role of language. Born from Sara Ahmed’s work in The Cultural Politics of Emotion, it presents a simplified equation (contact + orientation = emotion) as both a prescriptive and descriptive formula for making sense of human emotional experience. Starting with an exploration of the difficult-to-understand affect system, this dissertation identifies both rhetoric and affect as energies which cannot be understood apart from their traces, the things they move, produce, and become. As a way to get at these often-invisible forces, two trace studies are conducted which explore …

Additive Manufacturing With Bioresorbable Polymers: Process-Structure-Property Relationships For Biomimetic Tissue Scaffolds, Clayton Joseph Culbreath

All Dissertations

Tissue engineering has a base requirement of scaffold structures to support cell growth, proliferation, and regeneration. However, attempts to use artificial scaffold structures have often fallen short of clinical needs to justify the change away from the established, biologic-based current standard of care. Based on the limited number of successful tissue scaffolds produced by material extrusion modes of additive manufacturing, fused filament 3d printing and electrospinning, critical design specifications for a tissue scaffold are six minimum requirements: 1) biocompatibility, 2) porosity, 3) mechanical properties, 4) bioresorbable medical grade materials, 5) bioactivity, and 6) appropriately scaled production methods compliant with medical …

Despite this expanding number of MHealth apps, few demonstrate a foundation in empirical research. One design factor that may influence usability and effectiveness is the inclusion of virtual agents. Three studies were conducted to investigate users’ preferences for a variety of characteristics associated with virtual agents. In Experiment 1, users completed a single-session, three-stage CBT-based interaction with virtual characters and …

Evolution And Biogeography Of High Appalachian Rove Beetles (Staphylinidae), Adam Haberski

All Dissertations

The southern Appalachian Mountains are a region of great species richness and a center of endemism in many taxa, including flightless arthropods. High elevation refugia have facilitated the persistence of ancient lineages (paleoendemism) and in situ speciation (neoendemism), but their ubiquity, timing, and relative importance is unknown. Congruent patterns among co-distributed, but independent taxa might illuminate common drivers of Appalachian endemism. In this dissertation, I investigated the influence of allopatric speciation, geography, and paleoclimate events on the diversification of endemic species in two genera of rove beetles (Coleoptera, Staphylinidae), Lathrobium Gravenhorst and Ischnosoma Stephens, using an integrative morphological and molecular …

Inviting The Public Into Wildlife Research: Does Participation In Research Projects That Facilitate Interactions With Local Species Change Feelings Of Connection?, Seth Gibbons

All Dissertations

For many reasons, humans are less connected to nature. Research shows that people who feel more connected to nature are more likely to have pro-environmental intentions. One possible way to strengthen the human-nature connection is to involve the public in wildlife research, exposing them to local wildlife in a way that highlights science. This dissertation investigates two such projects, the 2019 Clemson Barred Owl Project and the Trout in the Classroom (TIC) program, to understand the effects of interacting with local species through wildlife research.

Interviews were conducted with participants and the lead researcher of the Clemson Barred Owl Project …

Mesenchymal Stromal Cell Response To Degenerated Intervertebral Disc-Like Ph, Kyle Cannon

All Dissertations

Intervertebral disc degeneration (IVDD) has become increasingly prevalent and is a common contributing factor to low back pain. There are currently no clinical treatment options for IVDD that alleviate the symptoms of IVDD while simultaneously promoting repair of IVD tissue. One treatment option being explored is intradiscal administration of mesenchymal stromal cells (MSCs). However, the microenvironment of the degenerating IVD places significant stress on both native IVD cells and implanted cells. There are several questions that need to be addressed which may help further inform the development of efficacious intradiscal MSC therapies for IVDD. These questions include: 1) Do MSCs …

Novel Nucleus Pulposus Biomaterial Development And Low Field Mri Assessment For Intervertebral Disc Degeneration, Mario Krussig

Intervertebral disc degeneration (IVDD) is a prominent pathology in the modern world that causes debilitating pain for many patients. The onset of IVDD occurs in the nucleus pulposus (NP). NP biomaterials will play a vital role in mitigating the progression of IVDD. Within this work, we sought to synthesize a solubilized extracellular matrix (ECM)-based NP biomaterial. Utilizing pepsin or urea extraction, bovine NP ECM was successfully solubilized (SBNPs). SBNP formulations were characterized biochemically, evaluated for cytotoxicity, and down-selected for front-running formulations. Leading candidate SBNPs were incorporated into an alginate bead biomaterial model to determine the potential bioactivity with human adipose-derived …

Optimizing Laying Hen Behavior, Bone Health, And Welfare Through Environmental And Nutritional Enrichments, Mallory Anderson

All Dissertations

The objective of this dissertation was to evaluate the impact of environmental and nutritional enrichments on the behavior, bone health, and welfare of Hy-line brown and Hy-line W-36 laying hens. Laying hens are prone to experiencing a progressive increase in bone fragility due to the ongoing mobilization of calcium from the bones for eggshell formation. Over time, this increases their susceptibility for bone fracture, which is a welfare concern. Prior research suggests that exercise, especially during the developmental stage, can aid in minimizing bone fractures by strengthening muscles and increasing bone mass. Furthermore, nutrition plays an integral role in laying …

Publications

This study draws on the practice of digital storytelling (DST) to address the limited use of technology in middle school multilingual classrooms. Through critical and multiliteracy frameworks, DST can help create a more engaging and inclusive learning environment that supports the literacy development of multilingual learners (MLs). After reviewing and synthesizing empirical studies on DST as it applies to the middle school years, we provide a crosswalk focusing on four core areas: content, context, communication and language, and student identity. The crosswalk reveals how DST integrates Web 2.0 technology and promotes language and literacy development among middle school MLs.
