Children represent a highly complex and variable population for treatment, including interindividual differences in drug dose-exposure. Midazolam has been used as a sedative for hospitalized children on- and off-label; however, factors affecting interindividual variability (IIV) in observed clearance for this population are not fully understood and can result in extreme under- or overexposure. Obesity has been described as a significant influence on midazolam in adolescents, which could potentially alter drug exposure. The goal of this study was to use two modeling strategies to evaluate dose-exposure of midazolam in children with and without obesity. Population pharmacokinetic modeling assessed whether measures of …

Background and Objectives: Neuropathy is a debilitating disorder characterized by peripheral nerve dysfunction and damage to sensory, motor, and autonomic neurons and their axons. While homozygous mutations in DNAJB2/HSJ1 have been linked to early-onset neuropathy, a heterozygous DNAJB2 c.823+6C>T was discovered in an adult patient with severe sensory–motor polyneuropathy. This mutation is predicted to affect both isoforms of the protein. DNAJB2 (HSP40), a key member of the heat shock protein family, plays a critical role in cellular protection and stress, including response to heat shock. DNAJB2 traffics unfolded proteins to another heat shock protein, HSP70, and activates its ATPase …

Theoretical And Experimental Synthesis Of Β-Fluorinated Morphine Derivative For Selective Binding In Inflamed Tissue, Thu Doan, Amelia Bayha, Adel Martinez, Nayiri Alexander
Student Scholar Symposium Abstracts and Posters
Over the past two decades, the United States has experienced a substantial rise in opioid overdoses and related fatalities. Morphine is a frequent prescription for pain management following traumatic procedures and contributes to potential tolerance and dependency with prolonged use. By reconstructing the structure of morphine, adverse side effects may be eliminated. Previous studies have identified several morphine derivatives that, in theory, could result in fewer side effects. This was determined by a decreased pKₐ of the biochemically active amine group to promote the selective binding in peripheral opioid receptors within inflamed tissue (pH=6-6.5). This activation provides analgesia while central …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers
The mitochondrial phosphate carrier (mPiC), encoded by the nuclear gene SLC25A3, is synthesized with an N-terminus mitochondrial targeting sequence (MTS), enabling its import into the mitochondria. mPiC imports inorganic phosphate (Pi) into the mitochondrial matrix for ATP production and other matrix phosphorylation reactions, as well as regulates mitochondrial Ca2+ uptake and buffering of matrix Ca2+. PiC also imports copper (Cu), crucial to COX subunit holoenzyme assembly. Variants in SLC25A3 exist and lead to mPiC deficiency (MPCD), cause a rare autosomal recessive disease with no current cure; patients with MPCD usually die within the first …

Investigating The Ability Of The Norepinephrine-Dopamine Reuptake Inhibitor Nomifensine To Reverse The Effort-Related Effects Of Tetrabenazine In Female Rats, Vivien Daytree
Honors Scholar Theses
Anergia, lassitude, and psychomotor retardation are core symptoms of motivational dysfunction that often accompany Major Depressive Disorder (MDD). While selective serotonin reuptake inhibitors effectively alleviate mood and anxiety symptoms, they remain relatively ineffective at alleviating motivational deficits. Compounds that elevate extracellular dopamine (DA) have shown promise in addressing these symptoms. Bupropion, a norepinephrine-dopamine reuptake inhibitor (NDRI), increases DA and is effective at attenuating motivational symptoms in patients. Another NDRI, nomifensine, has demonstrated potential antidepressant properties in preclinical research. Effort-based choice tasks, such as the FR5/chow choice task, serve as animal models for studying motivational dysfunction. Rats choose between exerting effort …

Computationally Assessing The Specificity Of Receptor Tyrosine Kinase Inhibitors, Htoo Say
Theses/Capstones/Creative Projects
Receptor tyrosine kinases (RTKs) are vital to cell signaling processes such as growth, survival, and differentiation. Dysregulation through mutation or overexpression often contributes to cancer, making RTKs key therapeutic targets for tyrosine kinase inhibitors (TKIs). However, the low specificity of many TKIs leads to off-target effects. This project uses molecular docking to evaluate the binding affinities and selectivity of FDA-approved TKIs across 18 RTK subtypes. The dockings conducted revealed significant variability in binding affinities, with Sorafenib exhibiting strong specificity for EphB2 (-7.6 kcal/mol) and poor compatibility with EphA7 and ErbB4 (-3.0 kcal/mol). These findings underscore the role of specific molecular …

The consequences of modulating subtypes of G protein coupled dopamine receptors are broadly studied for their role in decision making behavior, specifically in situations involving uncertain risk and reward. The actions of dopamine D4 receptors (D4Rs) on these complex processes are the least understood, particularly due to a lack of available compounds with suitable selectivity for D4Rs. Further, current research often fails to evaluate how modulating specific dopamine receptor subtypes may affect locomotor activity and anxiety-like behavior as confounding factors prior to assessing their function in behavioral assays of higher order decision making. The goal of the current study was …

Cobenfy(Xanomeline/Trospium) Vs. Clozapine For Treatment-Resistant Schizophrenia, Harmann Singh, Akash M. Patel, Abdullah Noory, Kush C. Patel, Simran Gandhi
Rowan-Virtua Research Day
Background: Treatment-resistant schizophrenia (TRS) poses significant therapeutic challenges. Although clozapine remains the gold-standard pharmacologic treatment for TRS, its clinical utility is hampered by severe side effects and intensive monitoring requirements. KarXT (Cobenfy), a combination of xanomeline and trospium chloride, represents a novel antipsychotic approach by targeting muscarinic M1/M4 receptors instead of dopamine D2 pathways.
Hypothesis: KarXT offers comparable efficacy to clozapine with a more favorable safety and tolerability profile, making it a viable alternative for patients with TRS.
Methods: A systematic review was conducted to identify studies from 2015–2025 evaluating KarXT in schizophrenia. Sources included PubMed, ClinicalTrials.gov, FDA databases, ICER …

Kratom As A Therapeutic Option For Opioid Use Disorder: A Comprehensive Review, Harmann Singh, Abdullah Noory, Akash M. Patel, Kush C. Patel, Simran Gandhi
Rowan-Virtua Research Day
Kratom (Mitragyna speciosa) has gained significant attention for its potential role in managing opioid use disorder (OUD). This review examines kratom’s pharmacology, safety profile, addiction potential, and ethical considerations in research, while exploring its future as a therapeutic option. Kratom’s primary alkaloids, mitragynine and 7-hydroxymitragynine, act as partial mu-opioid receptor agonists, producing analgesic and sedative effects at higher doses and stimulant-like effects at lower doses. Preclinical and observational studies suggest kratom may alleviate opioid withdrawal symptoms and cravings, but concerns remain regarding its dependency potential and adverse effects, including gastrointestinal distress, hepatotoxicity, and withdrawal symptoms upon cessation. While kratom carries …

Symptomatic Treatment Of Cannabis Withdrawal Syndrome: A Review Of The Existing Literature, Aria Sen, Dale Shober
Symptomatic Treatment Of Cannabis Withdrawal Syndrome: A Review Of The Existing Literature, Aria Sen, Dale Shober
Rowan-Virtua Research Day
Despite its public reputation as a recreational substance that does not cause physical withdrawal symptoms, cannabis withdrawal syndrome (CWS) was added to the DSM-5 in 2013. Existing research would suggest that almost half of regular cannabis users will experience symptoms such as mood symptoms, insomnia, and gastrointestinal distress. For more than 20 years, the rates of cannabis use have continued to trend upward due to expanding legislation on the recreational use of marijuana. Currently, there are no FDA approved treatments for CWS. Considering this trend, the lack of a well-formed treatment protocol for CWS will have a growing impact on …

Vaping has significantly increased among U.S. adolescents, driven by the rise of e-cigarettes and flavored pods. Nicotine exposure during brain development is linked to changes in the limbic-dopaminergic system, white matter integrity, and increased risk of emotional and behavioral dysregulation. Higher rates of depression, anxiety, and suicidality are reported among adolescent users, with greater symptom severity seen in those with high vaping dependence. Though studies show correlation rather than causation, findings suggest vaping may contribute to rising mental health diagnoses. Addressing vaping’s neurological and psychological impact is critical to guiding prevention efforts, regulatory policies, and support for at-risk youth.

Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are widely used to treat type 2 diabetes (T2DM) and obesity due to their benefits in glycemic control, weight loss, and cardioprotection. However, their effects on gastrointestinal (GI) motility raise concerns about potential complications, including bowel obstruction and, in rare cases, intussusception. We present a case of a 34-year-old male on semaglutide for weight loss who developed transient small bowel intussusception. The patient has no prior gastrointestinal surgeries or structural abnormalities, but he had a history of baseline slow bowel motility and was also diagnosed with influenza A during his hospitalization. His condition improved …

Serotonin syndrome, a potentially life-threatening condition, can be challenging to diagnose due to its diverse etiology and varied symptomatology. Despite its severity, serotonin syndrome may present from mild to fatal, with symptoms such as autonomic instability, altered mental status, and neuromuscular excitation (e.g. muscle rigidity, hyperreflexia). Here, we present a 20-year-old male with an extensive psychiatric history who was prescribed clomipramine and developed serotonin syndrome. Few cases of serotonin syndrome have been reported to date, exacerbating the difficulty in recognizing and quickly treating such cases. Cases of serotonin syndrome should continue to be reported, in order to familiarize clinicians with …
