Serotonin-Mediated Sickness Behavior, Audrey Harnagel

Student Theses and Dissertations

Serotonin is an ancient and powerful neuromodulator that regulates diverse processes from fundamental physiology to complex emotions. Due to the many functions of serotonin distributed throughout the body and brain, governing principles of serotonin signaling have remained elusive. There is particular interest in how serotonin modulates internal states given that serotonin dysregulation is a feature of many psychiatric diseases. In this thesis, I use the simplified serotonergic system of C. elegans to explore how serotonin governs the internal state of sickness. In addition to activating the immune system and remodeling physiology, pathogenic infection results in adaptive behavioral changes that promote …

Analysis Of Kcnj2 Variants Associated With Wolff-Parkinson-White Syndrome, Elaine Vanterpool, Kerenlaime Bautista

Student Posters

Wolff-Parkinson-White (WPW) syndrome is a cardiac disorder characterized by an accessory electrical pathway, leading to tachycardia and arrhythmias. It is diagnosed via electrocardiogram (ECG), showing a shortened PR interval and delta wave. WPW is typically managed with medications, catheter ablation, or surgery. Although primarily caused by anatomical anomalies, emerging research suggests genetic factors, including ion channel mutations, may contribute to the condition. The KCNJ2 gene encodes an inward-rectifier potassium channel critical for cardiac excitability. Mutations in KCNJ2 are linked to Andersen-Tawil syndrome, a disorder featuring arrhythmias and muscle weakness, raising questions about its role in WPW. This study investigates whether …

Presumptions Of Ai Malfunction: A Judicial Response To Ai Harms, Janine S. Hiller, Destynie J.L. Sewell

American University Law Review

In stark contrast to the recently revoked federal policy meant to incentivize the adoption of safe, secure, and trustworthy artificial intelligence systems, the July 2025 Winning the Race, America’s AI Action Plan succinctly summarizes its approach as “Build, Baby, Build!” Public discourse, as well, vacillates between artificial intelligence (AI) as a savior or an existential threat to society. To make effective decisions about AI governance, policy makers and regulators must not fail to recognize AI systems’ inherent weaknesses. Furthermore, whether citizens have recourse from harmful AI applications will also turn upon judicial balancing of competing interests between technological advancement and …

Kinetic And Thermodynamic Analysis Of Enpp1, Marisa Mary Michalchik

Yale Graduate School of Arts and Sciences Dissertations

The Ectonucleotide Pyrophosphatase Phosphodiesterase (ENPP) family members are promiscuous extracellular enzymes that play central roles in human physiology via catalysis of nucleotide and lipid substrates, but remain poorly characterized at the biochemical level. The founding member, ENPP1, is a glycosylated transmembrane enzyme with an extracellular catalytic domain that degrades nucleotide substrates (ATP and cGAMP) into their respective nucleotide monophosphates, playing a key role in both the regulation of biomineralization and innate immune system activation. The ENPP1 ATPase is the major source of extracellular pyrophosphate (PPi), the main chemical inhibitor of calcium phosphate crystal formation in physiology. ENPP1 deficiency lowers systemic …

Novel Nano-Formulations Based On Flash Nanoprecipitation For Ocular Drug Delivery, Lin Qi

Doctoral Dissertations

Effective ocular drug delivery has always been a challenge for clinical and research. Although many nanotechnology-based formulations have been developed and showed great potential in ocular drug delivery, this is far from enough to meet clinical requirements. These studies aimed at the design and synthesis of novel nanoparticles using multi-inlet vortex mixer (MIVM) to improve ocular drug delivery efficiency. The first project involves packaging two different anti-glaucoma drugs, brimonidine (BM) and betaxolol (BX), into solid drug nanoparticles (SDNs) by MIVM, which can achieve both functions, reducing aqueous humor production and promoting aqueous humor efflux. The studies demonstrate that the SDNs …

Bilirubin Hepatic And Intestinal Transport And Catabolism: Physiology, Pathophysiology, And Benefits, Zachary A. Kipp, Sally N. Pauss, Genesee J. Martinez, Terry D. Hinds, Jr., Wang-Hsin Lee

Pharmacology and Nutritional Sciences Faculty Publications

Bilirubin, a metabolite derived from heme degradation, has traditionally been regarded as a waste product and a marker of liver injury. However, increasing evidence suggests that bilirubin also functions as a hormone, and reduced levels are associated with metabolic dysfunction. Studies have shown a strong association between low circulating bilirubin levels and an increased risk of metabolic disorders and cardiovascular disease. To advance bilirubin-based treatment strategies, it is essential to elucidate the mechanisms underlying bilirubin transport and metabolism. Therefore, we provide an in-depth discussion of bilirubin production and its subsequent fates, with a particular focus on the transport between the …

Domain-Constrained Clustering: A Two-Stage Framework For Muscle Fiber Type Identification, Fanchao Yi
