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.

Do Dung Beetles Sink Or Swim: Exploring Dung Beetle Response To Precipitation, Lauren T. Cheshire

Graduate Theses, Dissertations, and Problem Reports (ETD)

Global climate change constitutes a major threat to biodiversity and ecosystem services of many taxa. The Mid-Atlantic region of the US is expecting to see an increase in extreme precipitation events and flooding. Dung beetles (Scarabaeinae) can tunnel below the soil surface allowing for water to dissipate into the soil rather than sit on the surface and add to flooding conditions. They also can decrease methane emission by burying dung and reduce outbreaks of pests that prefer the moist environment of dung. They contribute roughly $380 million in ecosystem services annually in the United States, yet their services may be …

Effects Of High-Frequency Repetitive Transcranial Magnetic Stimulation On Impulse Control Disorders In Patients With Parkinson’S Disease On Dopamine Replacement Therapy, Katherine Muksuris

Graduate Theses, Dissertations, and Problem Reports (ETD)

Parkinson’s Disease (PD) is a debilitating neurodegenerative disorder that causes motor deficits, cognitive impairment, and depression. The mainstay treatment for motor symptoms is dopamine replacement therapy (DRT). DRT takes the form of levodopa or dopamine receptor agonists (DAs) and can be associated with impulse control disorders (ICDs). Currently, the approach to mitigating these side effects is to decrease or stop DRT, which may cause motor symptoms to return, making the management of the disorder more difficult. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive neuromodulation treatment for multiple disorders, including its approved use for smoking cessation. It has also shown …

No Man’S A Stone: A Qualitative Approach To Characterizing Masculinity In Older Adulthood, Montgomery T. Owsiany

Graduate Theses, Dissertations, and Problem Reports (ETD)

Suicide rates are exceedingly high in U.S. older men (aged 65 years and older). In 2020, older men were about 6.5 times more likely to die by suicide than older women and 1.14 times more likely than men aged 18 to 64 years. Masculine norms (e.g., emotional suppression, self-reliance, anger, physical toughness risk-taking behaviors, alcohol misuse) are believed to influence the presentation of mental disorders, such as depression, which has led to the conceptualization of masculine depression. Research on masculinity often focuses on the experiences of younger men, ignoring how gender identities may change as one progresses through adulthood. Meanwhile, …

Co-Transmission Is Co-Opted For The Coordination Of Auditory Sensory Integration, Marryn M. Bennett

Graduate Theses, Dissertations, and Problem Reports (ETD)

Corollary discharge circuits (CDCs) are conserved mechanisms for sensory modulation during species specific behavioral programs. Many behaviors require multiplexed differential sensory modulation for proper execution. Co-transmission of fast and slow neurotransmitters allows for distinct modulation of different downstream targets within one sensorimotor circuit. However, studying co-transmission within the context of modulatory circuits like CDCs requires complete knowledge of behavioral circuits and precise tools for individually determining the implications of each transmitter on its targets. In this dissertation, I used a conserved set of corollary discharge interneurons in Drosophila melanogaster as a model to study the intricacies of sensory modulation through …
