The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough Oct 2025

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …


Pathogenesis And Therapeutic Considerations For Nonalcoholic Fatty Liver Disease, Elijah Chung Apr 2024

Pathogenesis And Therapeutic Considerations For Nonalcoholic Fatty Liver Disease, Elijah Chung

Senior Honors Theses

A product of the Westernized, high-fat diet, non-alcoholic fatty liver disease (NAFLD) has emerged as the leading cause of chronic liver disease, affecting one-fourth of the world's population. NAFLD is a progressive disease arising from a multisystem response to excess lipids in the blood, adipose tissue, and liver. Despite the prevalence of NAFLD and its well-studied bidirectional association with obesity and type 2 diabetes mellitus and obesity, there is a shocking scarcity of available treatments aside from diet and lifestyle changes. Thus, further research on NAFLD and potential therapies is urgently needed. This paper will illustrate the major pathways associated …


Intrinsic Apoptotic Pathway: Effects Of Calcium On Murine Cytochrome C Release In Brain And Liver Mitochondria, Dane M. Edwards Apr 2013

Intrinsic Apoptotic Pathway: Effects Of Calcium On Murine Cytochrome C Release In Brain And Liver Mitochondria, Dane M. Edwards

Senior Honors Theses

A cell may use one of three main apoptotic pathways leading to programmed cell death: the extrinsic pathway, the perforin/granzyme pathway and the intrinsic pathway. The most pertinent to this discussion is the intrinsic pathway, which utilizes the mitochondria as an essential intermediary. Mitochondria’s primary function in relation to this pathway is the subsequent release of pro-apoptotic factors including cytochrome c, which activate a caspase cascade leading to the death of the cell. Cytochrome c is released partly due to an increase in cytosolic calcium levels. Two methods of the release of cytochrome c have been proposed. The first is …
