Examining Drivers Of Brook Trout (Salvelinus Fontinalis) Fecundity And Recruitment In Central Appalachian Headwater Streams, Emilee Esther Briggs

Graduate Theses, Dissertations, and Problem Reports (ETD)

The persistence of fish populations depends on the repeated production and survival of new year classes, also referred to as recruitment. Recruitment is broadly defined as the number of individuals in a fish population or stock that survive to a specific stage. However, the broader recruitment process reflects the cumulative outcome of many earlier life stages, including egg survival, fry emergence, and survival through the recruitment period. As a result, recruitment can vary substantially among years and populations, producing strong or weak year classes that influence population abundance and persistence. Understanding why recruitment varies is therefore central to fisheries ecology …

Ornithine Metabolism In Retinal Pigment Epithelium And Retina And Implications In Gyrate Atrophy, Artjola Puja

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ornithine aminotransferase (OAT) is a mitochondrial enzyme that regulates ornithine metabolism by converting ornithine to pyrroline-5-carboxylate, a precursor for proline and glutamate synthesis. Deficiency of OAT causes systemic ornithine accumulation and leads to gyrate atrophy (GA) of the choroid and retina, a hereditary disorder characterized by progressive chorioretinal degeneration and irreversible vision loss. Chorioretinal atrophy typically starts at the mid-peripheral retina and progresses toward the macula. Although elevated ornithine is considered toxic to the eye, how ornithine is metabolized in ocular tissues and why OAT deficiency causes selective, region-specific vulnerability remain unclear. We combined ex vivo and in vivo stable …

Repurposing Cyclin-Dependent Kinase Inhibitors For The Discovery Of Novel Antiplasmodial Compounds, Ritam Bhowmik

Honors Undergraduate Theses

Malaria remains a major global health burden with over 282 million cases annually and rising resistance to artemisinin-based combination therapies. Plasmodium falciparum, the most lethal malaria parasite species in humans, relies on tightly regulated cell cycle progression during replication within red blood cells. Cyclin-dependent kinases (CDKs) are central regulators of eukaryotic cell division and transcription, and several CDK-like enzymes in P. falciparum, including Pfmrk and PfPK6, are essential for parasite growth and structurally distinct from human kinases. This study evaluated whether commercially available human CDK inhibitors (CDKIs) targeting cancer pathways could be repurposed as novel antimalarial compounds. A library of …

Manuka Honey Modulates Oxidative Stress In Neuro2-A Cells Through Mitochondrial Regulation, Rachel Abramovici

Honors Undergraduate Theses

Manuka honey is known for its vital usage in wound healing, being an agonist towards fighting infections, and is an acting antioxidant [32]. Its main constituents are flavonoids and phenolic compounds, with methyl syringate (MSYR) being a major active ingredient. The specific compounds responsible for these antioxidant effects, particularly in the CNS, remain unclear. It is hypothesized that pre-treatment of mouse neuroblastoma cells with MSYR followed by hydrogen peroxide exposure will activate the AMPK/SIRT1/PGC-1a pathway, due to MSYR’s phenolic structure, and thus reduce oxidative stress and improve mitochondrial biogenesis. Hydrogen peroxide is a standard reactive oxygen species (ROS) treatment to …

Investigating The Interaction Of Gram-Positive Lactobacillus Species With Mucin In The Context Of Barrett's Esophagus, Ritisha Suresh

Honors Undergraduate Theses

Gastroesophageal Reflux Disease (GERD) can progress to the precancerous Barrett’s Esophagus (BE) condition, in which the normal esophageal squamous epithelium is replaced with a columnar epithelium containing goblet cells. Mucins, sticky substances, are secreted in response to bile acid exposure during reflux episodes to protect the esophageal epithelium. Goblet cells secrete these mucins, which can also scaffold microbial colonization. Probiotic Lactobacillus bacteria can use glycosidase enzymes to process mucin and metabolize them into their component sugars (glycans). This project aims to identify the role of the Lactobacillus-mucin interaction in BE, as glycan availability could confer an advantage to Lactobacillus …
