The purpose of this single-arm, non-randomized, mixed-methods feasibility trial was to examine the feasibility and acceptability of the Virtual Reality Training Protocol for Sport (VRTPS), which was designed …

Beyond The Byproduct: Exploring Approaches For The Sustainable Valorization Of Underutilized Food Streams, Ian Phillip Israelsen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Commercial food processing creates side-streams that are often underutilized yet hold significant potential for valorization into value-added products for consumer use. This study investigated and compared potential protein recovery and lipid removal potential from buckwheat (BW; Fagopyrum esculentum Moench), brewer’s spent grain (BSG), and coffee silverskin (CSS) using a one-step solvent defatting and a pH-shift protein extraction method. The extraction efficiency yields of extracted protein from CSS were significantly lower than all other samples (p < 0.05). The defatted BW had the highest extracted protein content of all samples (p < 0.05). The sizes of the proteins in the starting materials were observed using LDS-PAGE. These sizes were consistent with published values and were mostly unchanged by defatting or the pH-shift process. The presence of 13S globulins and 2S albumins was confirmed under reducing conditions. Protein extracted from all native samples had lower total free essential amino acids than the starting materials. Native CSS and extracted protein followed this trend, but in defatted CSS and respective extracted protein samples, the extracted proteins had higher free essential amino acid content than the starting materials, sometimes of twofold or greater (p < 0.05). After defatting, the percentage of lipids recovered compared to the original lipid content of the samples was measured. The crude fat content of native and hexane-defatted BW flour was higher than BW flour defatted with ethanol (p < 0.05). The lipid extraction efficiency of all samples ranged from 4.6 ± 1.26%–43.20 ± 14.21%. The mass of the native and defatted starting materials were recorded at each step of processing, with reasonable losses assessed. The major non-polar lipid classes in each starting material were separated using thin-layer chromatography. All samples also displayed the presence of polar lipids. When comparing starting materials, BW and BSG was the most effective for protein extraction, and BSG has the most promise for lipid removal and potential for upcycling. All the examined starting materials show promise for use in food supplementation, especially as native flours. These products are plentiful and considered underutilized or side-stream products.

Neural And Computational Approach To Understanding Environmental Modulation Of Behavioral Identity In Zebrafish, John W. Hageter

Graduate Theses, Dissertations, and Problem Reports (ETD)

Organisms rely on behavior for survival. Animals engage in behaviors that allow for feeding, mating, exploring and navigating their environment among others. Necessary for these behaviors to develop are the environmental factors and underlying circuitry which make behavior possible. Specifically, how the environment guides underlying neural circuitry to develop unique facets or phenotypes of a larger behavior are key to understanding why unique behaviors exist. In this thesis, I build foundational evidence for determining these mechanisms through the use of the zebrafish local search behavior. This is a behavior that zebrafish employ following the loss of environmental illumination where they …

Engaging Young Children In Art Museums Through Interactive Programming, Rebekah K. Bostic

Graduate Theses, Dissertations, and Problem Reports (ETD)

Young children can be successfully engaged in art museum programs in many ways. Rather than identifying only one pedagogical strategy that is most effective for them, it is more productive to consider how different approaches affect the experiences of children in a museum. Despite the considerable body of existing research about educational strategies for preschool children, a clear synthesis of various pedagogical methods has not been applied to art museum programming for this age group. This research project used participant observation as its methodology to conduct four case studies attempting to answer the question: “How do different museum educational strategies …

The first chapter of this dissertation studies the impact that …

Reprogramming Of Immunometabolic Functions In Brain Microvascular Endothelial Cells During Neuroinflammation: Insights From Ischemic Stroke And Sepsis, Shokofeh Rahimpourkaldeh

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ischemic stroke and sepsis-associated encephalopathy (SAE) are two distinct conditions that share common pathophysiological mechanisms affecting brain microvascular endothelial cells (BMECs). Ischemic stroke results from an acute reduction in cerebral blood flow due to thrombosis or embolism, leading to energy failure, oxidative stress, and blood-brain barrier (BBB) dysfunction. SAE, a neurological complication of sepsis, arises from systemic inflammation, endothelial activation, and BBB disruption, leading to cognitive impairment and neuroinflammation. Despite their different etiologies, both conditions involve BMEC dysfunction as a central mediator of neurovascular injury. This dissertation aims to investigate the immunometabolic dysfunction of BMECs in ischemic stroke and sepsis, …

Skeletal And Dental Effects Of The Carriere Motion Appliance™ In Non-Growing Class Ii Patients: A Cephalometric Study, Anna Cathlyn Giles

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives: Dental and skeletal Class II discrepancies are commonly associated with orofacial disharmony, and therefore appear in orthodontic clinics frequently. Class II correction for adults is generally limited to camouflage treatment with extractions, Class II elastics, Class II correctors, distalization, or orthognathic surgery in severe cases. The orthodontic field is constantly innovating to find efficient and effective means to correct class II malocclusions. The Carriere Motion Appliance TM was introduced in 2004 as an effective “distalizing” appliance to be used as a non-extraction approach to Class II correction for adolescent and adult patients. Recent clinical evidence suggests that …
