Inhibition Of Glutathione Peroxidase, Tosin Masha, Carol Chrestensen, Daniela Tapu, Meleye Mel, Madison Jaames

Symposium of Student Scholars

Glutathione peroxidase (GPx) is an intracellular antioxidant enzyme that mediates the amount of hydrogen peroxide present in cells. Through this activity, GPx aids in the regulation of cellular processes that use hydrogen peroxide, including growth and proliferation. It may be desirable to inhibit GPx in certain diseased states, e.g. cancer, where GPx is over expressed. The Tapu lab is making N-heterocyclic compounds that have shown efficiency inhibiting thioredoxin reductase, which is another selenocysteine containing enzyme. Our aim is to test similar compounds to see if they have the ability to inhibit GPx. In order to test these compounds, we have …

Posterior Reversible Encephalopathy Syndrome After Dinutuximab, Kayeleigh Higgerson Do, Chandni Dargan Md

Research Days

Background: Posterior reversible encephalopathy syndrome (PRES) is a reversible disorder associated with edema of subcortical white matter and cortical gray matter that usually involves the occipital and parietal lobes. Endothelial injury secondary to abrupt blood pressure changes breaks down the blood brain barrier leading to brain edema. Per the ANBL0032 Fall 2015 Study Progress Report, Dinutuximab was the probable cause of PRES in two patients. There have been published reports of PRES with other anti-GD2 antibody therapies but very few reports of Dinutuximab as the causative agent.

Objectives/Goal: To report a case of PRES after Dinutuximab

Methods/Design: Case Report

Results: …

Activation Of Aryl Hydrocarbon Receptor Signaling In Human Trophoblasts Alters Markers Of Growth And Differentiation, Asmaa Alsousi

Research Days

Background: It is estimated that 1.7% of pregnant women smoke during their pregnancy globally, with the highest levels observed in Europe at 8.1%, and lowest in Africa at 0.8. The association of maternal cigarette smoking with increased risk of poor birth outcomes such as preterm birth, congenital anomalies, and neonatal mortality is well-established. In addition, evidence suggests that intrauterine exposure to maternal smoking impacts the risk of developing diseases later in life; however, we still do not understand the exact mechanism(s) leading to these outcomes. Once components of cigarette smoke (CS) cross the placenta and enter the fetal compartment, several …

Acute Flecainide Toxicity Treated With Intravenous Lipid Emulsion, Joseph S. Schreiner

Rowan-Virtua Research Day

Flecainide is a Vaughn-Williams class IC antiarrhythmic used in the treatment of supraventricular tachycardias including atrial fibrillation. While overdose is rare, its negative effects on cardiac inotropy and conduction pathways can be readily fatal. This is further complicated by the redistribution of the drug out of the plasma and deposition in tissue, rendering reversal by sodium bicarbonate (the standard first line treatment agent) relatively ineffective. A case study of the successful treatment of hemodynamic collapse using sodium bicarbonate in conjunction with intravenous lipid emulsion (ILE) in a patient who ingested a large amount of flecainide in a suicide attempt will …

Alteplase Used In A Child With An Acute Ischemic Stroke, Shah Nawaz Chaudhary, James Espinosa, Alan Lucerna, Adam Richards

Rowan-Virtua Research Day

Stroke, also known as cerebrovascular accident (CVA), is a neurological injury caused by inadequate brain perfusion due to either ischemia or hemorrhage. There is an abundance of literature on the management of ischemic strokes in adults and this has led to well-defined diagnostic and treatment guidelines. However, the management of pediatric ischemic strokes is currently based on clinical experience of experts, recommendations of consensus guidelines, case studies and extrapolation from adult clinical trials. In this case report, a pediatric patient suffering from an ischemic stroke is successfully treated with IV alteplase (tPA).

Case Presentation: Lower Back Pain Or Chronic Acetaminophen Overdose?, Meghan Whitt, Christopher Schwartz, Bhumi Shah

Rowan-Virtua Research Day

Unintentional ingestions can pose a difficult challenge to diagnose in the setting of the Emergency Department. Many may present with vague symptoms that are not consistent with classic overdose prodromes. Many patients do not identify or disclose over the counter medications, such as analgesics, with which acute/chronic ingestion in large quantities can result in life threatening medical emergencies. Their underlying symptoms may also cloud their clinical picture, further complicating workup within the ED.

Safety Of Silver Oxide Coated Biomaterials In Mice, Michael Klug, Darien L. Seidman, Rahyan Mahmoud, Destiny Morot, Lei Yu, Jeffrey D Hettinger, Renee M Demarest

Rowan-Virtua Research Day

It has been demonstrated that silver oxide coatings designed by our collaborators are able to prevent E. coli and P. aeruginosa attachment to biomaterials in vivo. These findings demonstrate that such coatings show promise in preventing the development of biofilm on biodevices. However, it is unknown if the use of silver oxide in this fashion is toxic in vivo. The goal of this project was to determine whether our silver oxide coatings are safe to use in vivo. To assess the toxicity of our silver oxide formula, mice were implanted with either silver oxide coated titanium discs or uncoated titanium …

Robotripping: The Dangers Of Abusing Dextromethorphan, Tiffany Sin, James Espinosa, Dana Fichter

Rowan-Virtua Research Day

Dextromethorphan (3-methoxy-N-methylmorphinan), also known as “DXM,” is a synthetically produced drug available in many over-the- counter (OTC) cough and cold medications as a centrally acting cough suppressant that binds to NMDA receptors. In a 2006 national survey of 50,000 students, 4, 5, and 7% of 8, 10, and 12th graders reported DXM abuse in the past year. In high doses, DXM can cause euphoria, hallucinations, dissociations, and distortion of cognition and perception. DXM abuse is also known as “Robotripping,” “Robodosing,” “Dexing,” “Tussin,” or “Triple Cs” because Robitussin® and Coricidin® Cough and Cold are most frequently abused. DXM has replaced codeine …

GREAT Day Posters

Human Leukocyte Antigen (HLA) is a gene that codes for cell-surface proteins that are the basis of our bodies’ immune response, and are crucial for the combatting of pathogens or infections. For our experiment we observed two cell lines, a human Leukemia cell line (HL-60), and an epidermoid carcinoma cell line A-431. Our purpose for this experiment was to observe the effects of two drugs as well as the combination of them on the expression of HLA antigens in these cancerous cell lines. The drugs being used in this experiment are Gamma interferon, which is known to increase antigen presentation …

Mediation Of The Uncoupled Enos Pathway Following Oxidative Stress Using Tetrahydrobiopterin And Nitric Oxide Donor Drugs To Restore Tetrahydrobiopterin Concentration, Brianna Munnich

Scholar Week 2016 - present

Presentation Location: Warming House, Olivet Nazarene University

Abstract

The eNOS pathway, found in the endothelium of blood vessels, is a key regulator of nitric oxide levels in the circulatory system. The pathway is controlled through several positive and negative feedback loops [2]. The cofactor tetrahydrobiopterin (BH4) is a major control point in this pathway and under conditions of stress can be reduced into the dihydrobiopterin (BH2) [2,6,7,8,9]. When the reduced form is predominant, the pathway produces reactive oxygen species (ROS) rather than nitric oxide, causing stress and damage to the vessels [6,7,8,9]. In this study, different treatments were studied …

Expression And Purification Of Hpep Inhibitor Peptide, Olivia Plaza

Undergraduate Research Conference

The enzyme human prolyl peptidase, or hPEP, has been linked to many processes within the brain, including breaking down neural peptides. A bovine milk protein, a-s1-casein (see above), has been found to inhibit hPEP in colon cancer cells. A 68 amino acid long section (bolded) of a-s1- casein containing the inhibitor region was cloned. The casein fragment expression was optimized for expression of the peptide. The purpose for optimizing expression is to have much of it on hand to utilize in further studies on its inhibitory properties on hPEP. By using this fragment of casein, one can study the structure …

A Novel Molecular And Cellular Study On Curcumin, Khang Nguyen

Undergraduate Research Conference

Since the discovery of G-quartet (G4)by M. Gellertin 1962, much attention has been given on G4and C4(also called i-motif) as important drug design targets for the treatment of various human disorders. G4 forming sequences are prevalent in human genome, which includes many important regions of the eukaryotic genome, such as telomere ends, regulatory regions of many oncogenes c-kit, proto-oncogene c-myc, Kirsten rat sarcoma viral oncogene homolog (KRas). Curcumin(diferuloylmethane), an antiinflammatory and antioxidant compound, is found in the rhizomes of the plant Curcuma longa. The phytopolyphenolic chemical curcumin has been in the prominence due to its diverse pharmacological activities. Here, we …

Development Of A Rapid Drug Detection Method For Insects Using Paper Spray Ionization Mass Spectrometry (Psi-Ms), Alexandria Plyler

Undergraduate Research and Scholarship Symposium

Insects have the ability to reflect the chemical environment that they have developed in. Thus, necrogenous insects can reflect the chemical environment of cadavers they have fed on. Forensic scientists can potentially utilize insect larvae as an alternate biological matrix to detect drugs in cadavers that are skeletonized, burned, or otherwise badly damaged. Analysis of insects using paper spray ionization mass spectrometry (PSI-MS), an analytical method requiring little to no sample preparation, could prove a rapid, cost-effective, and non-destructive alternative form of toxicological analysis. Traditional tissue analysis via GC and LC-MS often require lengthy sample preparation, use expensive reagents, and …

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 …

UNO Student Research and Creative Activity Fair

No existing model describes an identified special case of enzyme behavior when directly stimulated with thermal energy via an RF field.

The ability to remotely influence cellular functions and outcomes is a new approach to targeted medicine. Nano-medicine and biotechnology are the future of medical diagnostics and treatment. The ability to remotely influence cellular functions and outcomes is a new approach to targeted medicine. Direct heating of an enzyme vs bulk heating changes the enzyme activity.

I tested how direct transfer of thermal energy changes rates of enzyme reactions. We created samples of enzymes, attached to ferrous (magnetic) nano-particles, and …

Lowering The Cost And Raising The Efficiency Of A Cure To Chagas Disease, Madeleine Peters

Arkansas Women in STEM Conference

Chagas disease, classified as a neglected tropical disease (NTD), is caused by the parasite Trypanosoma cruzi and is an underfunded and under researched disease. The only FDA-approved drug in the United States is benznidazole which is expensive, harmful, and only effective in the illness’ acute phase. The goal is to create a more effective, lower costing and less harmful drug by using a condensation reaction to substitute different amines to diethyl squarate (DES) to make cycloalkylsquaramides. Both DES and the amines used are relatively low in price with a simple, efficient, and high yielding synthesis. Low synthetic cost and ability …

Synthesis Of N-Benzoyl-2-Hydroxybenzamides As Agents Utilized In Treatment Of Malaria, Brittany Krug, Gregory Naumeic

Arkansas Women in STEM Conference

Malaria is a disease that disproportionately affects several third world countries. It is a life-threatening illness that is transmitted by mosquitoes that act as vesicles for parasites. The parasites cause a febrile illness in those that are not immune. Children under five are most susceptible to the disease which can lead to multi-organ failure and death. The disease is preventable and curable, but according to the world health organization, countries disproportionately affected cannot afford these preventative care measures or have developed resistance to treatments. Therefore it would be advantageous to develop a new treatment for malaria that focuses on cost …

THE ROLE OF CANNABIDIOL IN THE TREATMENT OF PEDIATRIC PATIENTS WITH REFRACTORY EPILEPSY

Author(s) and affiliations: Evan Chidley¹, MMS (c), MPH (c)

¹Arcadia University; echidley@arcadia.edu; (515) 201-6901

Introduction: Intractable epilepsy in children can significantly impair quality of life and anti-epileptic drugs (AEDs) do not adequately reduce seizures for all pediatric patients. Recently, cannabidiol (CBD), one of the main compounds of marijuana, has shown promise as a potential treatment for uncontrolled seizure activity. This paper poses the following question: In pediatric patients with drug-resistant epilepsy, is cannabidiol (CBD) more effective in reducing seizure activity than traditional anti-epileptic drugs …

How The Amino Acid L-Serine Provides Neuroprotection Against L-Bmaa Induced Alzheimer’S Disease, Joseph Cimino

Capstone Showcase

More than 6 million people in America are living with Alzheimer’s Disease (AD) and there are currently no cures or treatments. It is time to move on from the ꞵ-amyloid hypothesis and broaden AD research. New research is suggesting that dietary exposure to a cyanobacterial toxin known as L-BMAA is causing neurodegenerative diseases such as AD, Amyotrophic lateral sclerosis (ALS), and Parkinson’s Disease. L-BMAA is misincorporated during protein folding, in place of the proper amino acid, L-Serine. It has been shown that the naturally occurring amino acid, L-Serine, can provide neuroprotection against L-BMAA, but the mechanism by which L-Serine infers …

Naloxone/Buprenorphine, Methadone, Naltrexone And Their Role In Medication Assisted Treatment, Robert Barrett

Capstone Showcase

Abstract

Opioid use disorder (OUD) is an increasingly common diagnosis that has drastically increased in the last 5 years. Though multiple treatment modalities exist for treating OUD (naltrexone, buprenorphine, methadone), few studies have compared treatment outcomes in adults on long term therapy. This is an important topic to understand as providers as we will undoubtedly come into contact with patients either actively abusing opioid antagonists or in recovery from opioid abuse. Since the introduction of Oxycontin and subsequent over prescription of opioid analgesics, opioid overdoses have increased by over twelve-fold. Once providers began to realize a widespread pattern of abuse, …

Opioid Use Disorder: The Timeline For Medication Assisted Therapy, Alexander Cristofori

Capstone Showcase

Opioid Use Disorder is patterns of opioid use leading to withdrawal, giving up important life events in order to use opioids, and excessive time spent using opioids, to name a few diagnostic criteria. The clinical progression of the disorder involves periods of acute exacerbation and remission that are cyclic in nature. Treatment is most effective when it includes both pharmacological and psychosocial modalities, referred to as medication assisted therapy (MAT). Three drugs used commonly in MAT-based treatment for OUD from oldest to newest include Methadone, Buprenorphine-naloxone, and Naltrexone. Treatment program models that prioritize total abstinence from the addictive substance attached …

Therapeutical Studies Of The Disrupted Cftr Gene In Affected Sheep And Rabbit Models Produced By Genome Editor Crispr/Cas9, Nicole Teberio

Capstone Showcase

Cystic Fibrosis (CF) is a life-threatening, autosomal recessive disorder caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. Patients with CF have a decreased lifespan due to complications with lung infections/disease, decreased airway function, and persistent cough with phlegm. Over the past few decades, scientists have contributed to CF research by using animal models to understand the pathology of the disease. The models selected have similar pathogenesis to humans, so they are key insights for understanding the effects of CFTR gene malfunctions. More recently, animal models, such as CRISPR generated sheep and rabbits used in the two current …
