Adipokines Mediate Fat-To-Ovary Communication To Regulate Oogenesis, Adipocyte Size, And Lipid Storage In Drosophila Melanogaster, Chad Herbert Simmons
Theses and Dissertations
Humans have complex signaling pathways that allow them to store and expend energy based on nutritional quality and availability. Inter-organ signaling is used to communicate nutrient availability between organs based on nutritional needs and the rate of cellular division. Our main overarching question is to investigate how fat-derived signals affect adipocyte morphology and the maintenance of stem cells in the ovary. While signaling pathways, like insulin and mTOR, and some adipokines that are involved in inter-organ nutrient sensing have been identified, the exact nutrient reliant mechanisms of stem cell maintenance are not completely understood. Using Drosophila melanogaster as a model, …
Hearing The Difference: Just Intonation Techniques Utilizing Distortion Product Otoacoustic Emissions In Viola Performance, Calj Green Umezono
Hearing The Difference: Just Intonation Techniques Utilizing Distortion Product Otoacoustic Emissions In Viola Performance, Calj Green Umezono
Theses and Dissertations
Difference tones, also known as distortion product otoacoustic emissions, are the result of active phenomena in the human cochlea during the conversion of sound waves into bioelectrical signals. Difference tones make it possible to explore alternative musical tuning systems beyond the twelve-tone, equally tempered regime. Musicians have investigated difference tones since the 18th Century in Euro-American musical contexts, but their application has so far been limited in scope. Advances in science, technology, and music theory from the late 19th Century through the early 21st Century have given present-day violists the opportunity to more fully understand the virtues of difference tones …

Predictors Of Outpatient Follow-Up Attendance And Subsequent Psychiatric Readmission, Sandra J. Beltran
Predictors Of Outpatient Follow-Up Attendance And Subsequent Psychiatric Readmission, Sandra J. Beltran
Theses and Dissertations
Psychiatric readmissions remain a persistent challenge in mental health care, often reflecting gaps in continuity of treatment following discharge. The Agency for Healthcare Research and Quality (2019) indicated that a key component in preventing inpatient readmission is adequate outpatient care following discharge. Moreover, early attendance in outpatient follow-up visits is associated with improved patient outcomes (Boston Medical Center, 2022). Various predictors are associated with engagement in outpatient services, such as age, medication compliance, and socioeconomic variables (Carson et al., 2014; Li et al., 2005; Marino et al., 2016; Stubbs et al., 2024).
The present study sought to determine whether psychiatric …

Exploring The Diversity And Biology Of Unique Giant Broad Host Range Bacteriophages In Natural Environments, Tannaz Mohammadi
Theses and Dissertations
Microbial interactions within the rhizosphere play a crucial role in shaping bacterial community diversity and function. To explore these dynamics, we isolated 21 bacterial strains from soil and plant root samples collected near Rocky Branch Creek on the University of South Carolina campus. Our findings revealed that a significant proportion of these bacteria are lysogenic for CbK-like phages belonging to the Dolichocephalovirinae subfamily. Additionally, we isolated free bacteriophages directly from the same soil samples and found them to be closely related to those harbored within lysogenic bacteria. Surprisingly, despite predictions of a narrow host range, most of these phages, both …
The Role Of Prelimbic Projections To The Rostromedial Tegmnetal Nucleus In Cue Discrimination, Emma Lane Carlson
The Role Of Prelimbic Projections To The Rostromedial Tegmnetal Nucleus In Cue Discrimination, Emma Lane Carlson
Theses and Dissertations
Maladaptive decision-making, such as persistent reward seeking despite negative consequences, is a hallmark of substance use disorder (SUD) and related psychiatric conditions. These behaviors are thought to arise from impairments in aversive learning and disrupted neural signaling that normally supports behavioral inhibition. The prelimbic cortex (PL) plays a critical role in encoding cue–outcome associations and exerting top-down control over behavior, while the rostromedial tegmental nucleus (RMTg) serves as a GABAergic inhibitor of midbrain dopamine neurons in response to aversive stimuli. Although both structures have been implicated in reward and avoidance processes, little is known about how direct PL-RMTg projections contribute …

Development Of A Strategy To Neutralize Ccl8 Activity And Ablate Ccl8 Cellular Targets, Bernardo Chavez
Development Of A Strategy To Neutralize Ccl8 Activity And Ablate Ccl8 Cellular Targets, Bernardo Chavez
Theses and Dissertations
The chemokine CCL8 (monocyte chemoattractant protein-2) is a versatile signaling molecule involved in tumor progression, immune cell recruitment, and therapeutic resistance. Through activation of receptors including CCR1, CCR2B, and CCR5, CCL8 promotes leukocyte trafficking, epithelial–mesenchymal transition, and the establishment of immunosuppressive tumor microenvironments. In breast cancer and inflammatory diseases, elevated CCL8 levels correlate with poor clinical outcomes, making it a promising therapeutic target.
A strategy was developed to block CCL8 activity and selectively ablate CCL8 receptor expressing cells. A neutralizing monoclonal antibody, 1G3E5, was identified from a panel of murine candidates based on high affinity CCL8 binding. Sequencing revealed two …

Too Much Of A Good Thing? Can Students Be Too Behaviorally Engaged, Rosemary Louise Odem
Too Much Of A Good Thing? Can Students Be Too Behaviorally Engaged, Rosemary Louise Odem
Theses and Dissertations
Student engagement in school is a key determinant of students’ academic success. Student engagement is commonly conceptualized as a meta construct comprised of three dimensions: emotional, cognitive, and behavioral engagement (Fredricks, 2015). Behavioral engagement, the focus of this study, is defined by positive conduct, involvement in learning and academic tasks, and participation in school-related activities (Fredricks et al., 2004). Some researchers have suggested that psychological strengths, like engagement, can be overused and result in maladaptive consequences (Niemiec, 2019; Oishi et al., 2007). This study addressed this notion using archival data from a sample of 422 students from one Southeastern US …

Gut Microbiome Dynamics In Heart Failure And The Therapeutic Potential Of Nmeg-Cgrp, Kamryn Michael Gleason
Gut Microbiome Dynamics In Heart Failure And The Therapeutic Potential Of Nmeg-Cgrp, Kamryn Michael Gleason
Theses and Dissertations
Heart failure (HF) is increasingly recognized as a multisystem disease often linked to gut dysbiosis; however, its specific effects on gut microbial composition remain poorly understood. This study examined long-term changes in the gut microbiome in a murine HF model induced by transverse aortic constriction (TAC) and evaluated the effects of NMEG-CGRP. TAC mimics pressure overload-induced cardiac dysfunction, replicating key features of HF. CGRP, a neuropeptide with vasodilatory and cardioprotective effects, shows potential as a therapy for HF but is limited by rapid degradation. A stabilized analog, NMEG-CGRP, was used to assess its impact on cardiac and gastrointestinal health. Mice …
