Assessing The Impact Of Toxic Fescue Consumption During Gestation On Muscle Growth Gene Expression And Beef Color Quality Of The Offspring, Madison Blank

Animal Science Undergraduate Honors Theses

Endophyte-infected tall, toxic fescue is the most common forage for beef cattle in the southeastern U.S. However, exposure to this forage causes detrimental effects on the health of gestating cattle. The exposure to toxic fescue during gestation has been shown to impact fetal development during pregnancy and their offspring’s subsequent growth. However, limited information is currently available on the impact of this exposure on the meat quality of the offspring. Our objective is to determine how the dam’s exposure to toxic fescue during gestation impacts the beef color and quality of the final offspring.

Oxytocin-Mediated Trust Formation In Relationship-Based Sales, Isabella G. Farrington

Biological Sciences Undergraduate Honors Theses

Trust is a critical driver of success in relationship-based sales, particularly in complex environments such as medical, pharmaceutical, and B2B markets where decisions involve uncertainty, risk, and long-term commitment. Existing research in marketing and psychology primarily explains trust through interpersonal behaviors, communication, and relationship management strategies. However, the biological mechanisms underlying trust formation remain largely underexplored in these contexts.

This thesis examines the role of oxytocin, a neuropeptide associated with social bonding and cooperation, in shaping trust and decision-making in professional sales environments. Drawing on research from neuroscience, neuroeconomics, and relationship marketing, it proposes that oxytocin-mediated processes provide a biological …

From Chaos To Clockwork: Investigating The Role Of Circadian Genes In Metabolic Development Of 2nd And 3rd Instar Drosophila Larvae, Elliott R. Ruegsegger, Stephanie Hood, Amy Poe

Biological Sciences Undergraduate Honors Theses

Circadian clocks regulate daily physiological and metabolic rhythms across many organisms. In Drosophila melanogaster, the molecular clock involving period (per) and timeless regulates gene expression across 24-hour cycles. Circadian rhythms are well characterized in adult, mature organisms, but their emergence during early developmental stages remain poorly understood. In D. melanogaster, the circadian regulation of sleep and feeding rhythms emerges during the 3rd instar larval stage. This suggests that the circadian regulation of metabolism may also arise during this stage. Further, the metabolic consequences of circadian clock disruptions during this developmentally rich period remain unclear. This research aimed to …

Social Isolation Predicts Altered Reward Circuit Connectivity And Future Behaviors In Adolescents, Mason Lucas, Josiah Leong

Psychological Science Undergraduate Honors Theses

Adolescence is a period of transition from childhood to adulthood when people explore risky behaviors, and stressors during adolescence can change structural brain connectivity. Previous research has found weaker structural connectivity between reward circuits and future cognitive impairments among children raised in orphanages. Comparative research in mice suggests that social isolation after bullying can damage these connections and induce alcohol seeking. We tested whether social isolation was related to lower connectivity of targeted structural connections and anxious behaviors in adolescent humans. We analyzed data from the Adolescent Brain Cognitive Development study and found 522 subjects had experienced extreme social isolation. …

Structural Evidence For Innervation Of A Single Epitheliomuscular Cell By Multiple Sensory Neurons In The Sea Anemone Nematostella Vectensis, Aparajita Das

Graduate Theses and Dissertations

Abstract Here, I report new ultrastructural evidence for multineuronal innervation (many-one) of a single epithelia-muscular cell in sea-anemone cnidarian Nematostella vectensis. Using Serial Block-Face Scanning Electron Microscopy (SBF-SEM) and ImageJ, I found that EMCs are located at the base of ectoderm, with an elongated cell body that includes basal processes, a bilobed nucleus, and myofibrils aligned parallel to the basal surface along with their structural quantification. Notably, I found multiple mechanosensory neurons form synapses with a single EMC. These findings enhance our understanding of cnidarian neuromuscular organization and reveal that coordination between sensory and contractile systems in N. vectensis is …
