Effects Of Dexmedetomidine As An Adjunct To General Anesthesia On Postoperative Pain And Opioid Consumption In Major Abdominal Surgery, Ahmad H. Elrefahy
Effects Of Dexmedetomidine As An Adjunct To General Anesthesia On Postoperative Pain And Opioid Consumption In Major Abdominal Surgery, Ahmad H. Elrefahy
Rowan-Virtua Research Day
This review examines the impact of dexmedetomidine, an alpha-2 adrenergic receptor agonist, on postoperative pain and opioid consumption in major abdominal surgery. Dexmedetomidine, known for its sedative, analgesic, and opioid-sparing properties, is increasingly used as an adjunct to anesthesia. Analyzing existing literature, the review found that dexmedetomidine administration alongside general anesthesia significantly improves postoperative pain management and reduces opioid consumption. Patients receiving dexmedetomidine reported decreased postoperative pain ratings and required fewer opioids during the recovery phase. Additionally, intraoperative dexmedetomidine use correlated with reduced postoperative pain severity and increased patient satisfaction compared to control groups. However, potential side effects such as …

Mechanistic Investigation Of C—C Bond Activation Of Phosphaalkynes With Pt(0) Complexes, Roberto M. Escobar, Abdurrahman C. Ateşin, Christian Müller, William D. Jones, Tülay Ateşin
Research Symposium
Carbon–carbon (C–C) bond activation has gained increased attention as a direct method for the synthesis of pharmaceuticals. Due to the thermodynamic stability and kinetic inaccessibility of the C–C bonds, however, activation of C–C bonds by homogeneous transition-metal catalysts under mild homogeneous conditions is still a challenge. Most of the systems in which the activation occurs either have aromatization or relief of ring strain as the primary driving force. The activation of unstrained C–C bonds of phosphaalkynes does not have this advantage. This study employs Density Functional Theory (DFT) calculations to elucidate Pt(0)-mediated C–CP bond activation mechanisms in phosphaalkynes. Investigating the …

Research Symposium
Los cánceres de pulmón, próstata e hígado se encuentran entre los más prevalentes en los hombres. El cáncer de mama, de cuello uterino y de tiroides se encuentran entre los más prevalentes en mujeres (OMS, 2019). El tratamiento del cáncer generalmente incluye quimioterapia y radioterapia; sin embargo, los medicamentos contra el cáncer disponibles tienen una selectividad baja y causan efectos adversos graves, como nefrotoxicidad, neurotoxicidad y mielosupresión (Matsuo et al., 2010). Por tanto, el diseño y desarrollo de compuestos como nuevos agentes anticancerígenos frente a los tipos de cáncer de mayor incidencia son de vital importancia en el campo de …
Growing Use Of Xylazine As An Adulterant In Opioids And Its Effects, Oluwapelumi Oluwo
Growing Use Of Xylazine As An Adulterant In Opioids And Its Effects, Oluwapelumi Oluwo
Rowan-Virtua Research Day
Xylazine, according to the National Institutes of Health (NIH), is a non-opioid tranquilizer used in veterinary medicine. Although this drug has not been approved for human use, it can be linked to an increase in opioid overdose deaths due to its role as an adulterant in drugs like fentanyl.
Xylazine was detected in drugs involved in 41% of all opioid-involved unintentional deaths and in 44% of all unintentional overdose deaths with fentanyl involved in the year of 2021 in Philadelphia.
Triazole Compounds – Potentials In The Treatment Of Cystic Fibrosis, Maggie Taylor
Triazole Compounds – Potentials In The Treatment Of Cystic Fibrosis, Maggie Taylor
Undergraduate Research Conference
Cystic Fibrosis (CF) is a genetic disease that affects the respiratory and digestive system and is most common among Caucasians of Northern European origin. CF is caused by mutations in a membrane protein CFTR (Cystic Fibrosis Transmembrane-conductance Regulator). This mutation impairs the membrane protein’s chloride ion channel function. One of the most common CFTR mutations is the DF508 mutation that affects over 70% of CF cases. Our research has shown that the DF508-CFTR mutation can be partially reversed by physical and chemical means [Heda & Marino, BBRC, 271:659-664, 2000]. In cell lines expressing DF508-CFTR, synthetic anion carriers have shown to …
Designing And Synthesizing A Warhead-Fragment Inhibitory Ligand For Ivyp1 Through Fragment-Based Drug Discovery, Samuel Moore
Designing And Synthesizing A Warhead-Fragment Inhibitory Ligand For Ivyp1 Through Fragment-Based Drug Discovery, Samuel Moore
Symposium of Student Scholars
Fragment-based drug discovery (FBDD) is a powerful tool for developing anticancer and antimicrobial agents. Within this, magnetic resonance spectroscopy (NMR) provides a comprehensive qualitative and quantitative approach to screening and validating weak and robust binders with targeted proteins, making NMR among the most attractive strategies in FBDD. Inhibitor of vertebrate lysozyme (Ivyp1) of P. aeruginosa serves as an excellent target because of its active cellular location and implications in clinical prognosis for cystic fibrosis and immunocompromised patients. This study uses current NMR and biophysical techniques to develop a covalent, fragment-linked warhead inhibitor for Ivyp1 through synthetic methods, warhead linking, and …

Treating Trichotillomania With Olanzapine, Christopher Lee
Rowan-Virtua Research Day
Trichotillomania (TTM) is characterized by repetitive pulling of one’s hair leading to hair loss and problems in social, occupational, or other important areas of functioning. Often individuals with TTM try to decrease or stop hair pulling, however are often unsuccessful without treatment. Community prevalence studies suggest that TTM is a common disorder with point prevalence estimate of 0.5% to 2.0% and with significant psychological comorbidity. Of note, people with TTM are often embarrassed about their condition, so epidemiology data may be underestimated compared to the true prevalence of this condition. The female to male ratio for this condition is 4:1. …

Synthesis Of 5-Membered Ring Heterocycles For Alzheimer’S Disease, Daniel Fajardo
Honors Scholars & Undergraduate Research Poster Symposium Programs
The progression of Alzheimer’s disease (AD) is correlated to the degenerative activation of muscarinic acetylcholine receptors (mAChR) located in the brain. They are a family of five G-protein coupled receptors, (M1-M5), linked to functions within the central and peripheral nervous system.1 More specifically, activation of M1 with positive allosteric modulators (PAM), have shown to bind to the allosteric pocket and slow the degenerative process of AD with minimal intrinsic effects.2 Structural motifs of potent PAM activity and weak agonism proposed a synthesis of an isooxazoline compound, incorporating a 1,3-dipolar cycloaddition. The core motif of the proposed isooxazoline structure has been …

Celebration of Research and Creative Scholarship
Cancer is currently the second leading killer disease. There are many different kinds of cancer that are associated with almost every organ in the human body (e.g., brain cancer, colon cancer, breast cancer, prostate cancer, blood cancer, lung cancer, etc.).
In the Biology Department, Dr. Smith and Dr. Murray are researching glioblastoma brain cancer cells. Glioblastoma is a very invasive cancer that is highly lethal. Chances of not surviving when its at stage four is more than 98%. Detecting this cancer while it is developing is difficult because symptoms are mild headache, fatigue, nausea and slight loss of weight. By …

Stable Nanopalladium Hydride In Water For Sustainable And Selective Reductions, Jesse Klus, Sachin Handa
Posters-at-the-Capitol
The synthesis of air-stable ligand-free nanopalladium hydride (PdNHx) in water was achieved and applied to various organic transformations, including (1) reduction of heteroaromatics such as (iso)quinolines, phenanthrolines, benzotriazole, and naphthyridines, (2) regio- and chemoselective reduction of nitroarenes, (3) alkyne reductions, (4) chemoselective dehalogenation, and (5) base-free detriflation. Both the synthesis of PdNHx and the reductions were carried out under mild conditions in a micellar medium using our designer surfactant PS-750-M, which eliminates the need for toxic organic solvents and extremely high hydrogen pressure and temperature. Notably, PS-750-M is also a replacement of hazardous polar-aprotic solvents. This newer approach for selective …

The Summer Undergraduate Research Fellowship (SURF) Symposium
c-di-AMP is a global stress response regulator involved in some processes of biofilm formation and antibiotic resistance. It has become a candidate target for the development of new antibacterial treatments. Previous studies have shown that hydroxybenzylidene-indolinones can act as c-di-AMP synthase inhibitors. They also act as antibacterial and anti-biofilm inhibitors and re-sensitize resistant bacteria to methicillin and vancomycin. In this project, potent analogs of these compounds, including Schiff bases and N-substituted compounds, have been synthetized. The objective of this work is to explore the effect of these modifications on their biological activity. Base-catalyzed condensation and acid-catalyzed reactions were performed in …
