Undergraduate Theses, Capstones, and Recitals
Polyamines, and their rate-limiting enzyme ornithine decarboxylase (ODC), are crucial for many functions in the central nervous system but levels decrease with age. In neurodegenerative diseases, like Alzheimer’s Disease (AD), polyamine levels begin to increase again. Yet, there are still many unanswered questions surrounding polyamine’s possible role in AD, especially in those with Down Syndrome (DS), who also have an extra copy of the amyloid precursor protein (APP) and tend to get AD far earlier than the general population. We aim to investigate if there is colocalization between amyloid plaques and Ornithine Decarboxylase (ODC) in patients with AD and AD/DS, …

Mild traumatic brain injury (mTBI), yielding a Glascow Coma Scale of 13-15, is the most commonly occurring severity of TBI. Pathology from mTBI consists of blood brain barrier disruption, neuroinflammation, oxidative stress, excitotoxicity, mitochondrial dysfunction, protein aggregation, axonal degeneration, and resulting neuronal death. These processes deplete the body’s endogenous antioxidant system. We report a retrospective analysis of antioxidant blood biomarkers in patients with a history of mTBI from a local sports medicine clinic, Resilience Code. We found persistent sex-specific antioxidant depletions in mTBI patients associated with worsened symptomology.
Certain populations, such as athletes, are at high risk for repetitive mTBI …

Zinc (Zn2+) is crucial for proper cellular function, and as such it is important to measure and track Zn2+ dynamics in living cells. Fluorescent sensors have been used to estimate Zn2+ content of subcellular compartments, but little is known about endolysosomal Zn2+ homeostasis. Similarly, although numerous sensors have been reported, it is unclear whether and how Zn2+ can be released from intracellular compartments into the cytosol due to a lack of probes that can detect physiological dynamics of cytosolic Zn2+. My dissertation started with comparing and characterizing different Zn2+ sensors including the …
