Barrett, The Honors College Thesis/Creative Project Collection
Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.
Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Description
Osteosarcopenia is a newly formed term that combines the symptoms of osteoporosis and sarcopenia together because of their concurrent appearances in life. They are both age-related, debilitating conditions that affect older adults’ skeleton and musculoskeletal system. Osteoporosis specifically targets the cells of the bone and make them weak and porous. Sarcopenia attacks the skeletal muscles and deteriorates the muscle fibers, decreasing mass and strength. Both diseases put sedentary elders at high risk of sustaining fractures and proneness to fall. The manifestation of one condition typically leads to the other because of their obvious physical attachments as well as their direct chemical crosstalk. The onset of osteosarcopenia is subtle coinciding with age related processes that become greatly exacerbated and accelerated when coupled with chronic inactivity. Thus, a critical intervention for managing the disability associated with osteosarcopenia is physical activity. While some pharmacological treatments or supplements are known to have positive results in stemming further bone loss, regular participation in moderate-intensity exercises is considered the most effective treatment for attenuating further bone and muscle loss.

Description
Birds maintain resting plasma glucose concentrations (pGlu) nearly twice that of comparably sized mammals. Despite this, birds do not incur much of the oxidative tissue damage that might be expected from a high pGlu. Their ability to stave off oxidative damage allows birds to serve as a negative model of hyperglycemia-related complications, making them ideal for the development of new diabetes treatments with the potential for human application. Previous studies conducted by the Sweazea Lab at Arizona State University aimed to use diet as a means to raise blood glucose in mourning doves (Zenaida macroura) in order to better understand the mechanisms they utilize to stave off oxidative damage. These protocols used dietary interventions—a 60% high fat (HF) “chow” diet, and a high carbohydrate (HC) white bread diet—but were unsuccessful in inducing pathologies. Based on this research, we hypothesized that a model of an urban diet (high in fat, refined carbohydrates, and sodium) might impair vasodilation, as the effect of this diet on birds is currently unknown. We found that tibial vasodilation was significantly impaired in birds fed an urban diet compared to those fed a seed diet. Unexpectedly, vasodilation in the urban diet group was comparable to data of wild-caught birds from previous research, possibly indicating that the birds had already been eating a diet similar to this study’s urban diet before they were caught. This may constitute evidence that the seed diet improved vasodilation while the urban diet more closely mimicked the diet of the birds before the trial, suggesting that the model of the urban diet acted as the control diet in this context. This study is the first step in elucidating avian mechanisms for dealing with diabetogenic diets and has potential to aid in the development of treatments for humans with metabolic syndrome.
