Hydrogen Peroxide Colitis: The Accidental Enema, Ramin Karimi, Ashish Sharma, Kevin Tran, Sebastian Montgomery

HCA Healthcare Journal of Medicine

Chemical colitis is defined as inflammation of the large intestine or colon as a result of exposure from a harsh chemical through an enema or other procedure. In this case, the chemical is hydrogen peroxide, which is commonly used as an antiseptic for minor abrasions. Hydrogen peroxide enemas were once popular for difficult to treat constipation. However, resultant colitis and proctitis limited its use. When administered rectally in a high enough concentration, intense abdominal pain and transient bloody diarrhea can occur, with the majority of affected patients making a full recovery with supportive management. Here we discuss a case of …

The Effects Of Progesterone Induced Blocking Factor And 17-Hydroxyprogesterone Caproate On The Pathophysiology Of Preeclampsia, Kyleigh M. Comley

Honors Theses

Preeclampsia (PE) is responsible for about 20% of the 13 million preterm births each year worldwide, including 100,000 cases annually in the United States. Despite being a leading cause of maternal and perinatal morbidity, the mechanisms of pathogenesis are still largely unknown. PE is progesterone deficient state characterized by hypertension, chronic immune activation, endothelial dysfunction and severe forms can lead to seizures. Treatment of seizures includes the administration of magnesium sulfate (MgSO4) though not all PE patients are responsive, and it does not decrease PE-associated hypertension. To resolve these conditions, PE patients are delivered early thereby making PE the leading …

Synthesis Of Novel Long Chain Unsaturated Fatty Acid Analogs Of Capsaicin, Eli Bettiga

Honors Theses

A number of key studies have shown that the natural product capsaicin displays in vitro and in vivo antitumor effects against a variety of cancers, however, both the analgesic and cancer-related therapeutic potential of capsaicin have been limited by its unpleasant pungent side effects and modest potency. N-acyl vanillylamides (N-AVAMs) are a unique class of compounds that are simple side chain modified capsaicin derivatives. Limited structure-activity relationship (SAR) studies of N-AVAMs demonstrated that substitution of the capsaicin side-chain with longer unsaturated fatty acid groups results in non-pungent analogs with improved anti-invasive activity relative to capsaicin. In an effort to ultimately …

Drug Repurposing And Dosage Form Development Of Anti-Covid-19, Kevin Kwok

Pharmaceutical Sciences and Research

The COVID-19 pandemic has been occurring approximately for more than 1 year. This pandemic has been a health issue that hits all countries in the world caused by the transmission of SARS-CoV-2 virus from one individual to another. The symptoms showed from the infected are fever, shortness of breath, dry cough, headache, and sore throat, among others. The SARS-CoV-2 virus is transmitted through sneezing, coughing, talking, and touching infected objects. Along with this transmission, the SARS-CoV-2 virus will continue to mutate. This mutation becomes an obstacle as well as a challenge to find drugs that can overcome the SARS-CoV-2 virus …

Use Of Antisense Oligonucleotides To Target Notch2 In Mouse Chondrocytes, Gabrielle Viviana Lanza

Honors Scholar Theses

NOTCH2 is a transmembrane receptor that is part of the Notch receptor family, known for controlling cell differentiation and function. Notch receptors play a crucial role in skeletal development and bone homeostasis. Hajdu Cheney Syndrome (HCS) is a rare monogenic disorder affecting the skeleton caused by a gain-of-function mutation in NOTCH2. Antisense oligonucleotides (ASO) are sequence-specific single-stranded nucleic acids that bind to target mRNA and initiate mRNA degradation. While previous work has explored the role of Notch2 ASOs in osteoblasts and osteoclasts, this paper explores the role of Notch2 and Notch2 ASOs in cells of cartilage tissue. The effect of …

Ciliary Extracellular Vesicles Are Distinct From The Cytosolic Extracellular Vesicles, Ashraf M. Mohieldin, Rajasekharreddy Pala, Richard Beuttler, James J. Moresco, John R. Yates Iii, Surya M. Nauli

Pharmacy Faculty Articles and Research

Extracellular vesicles (EVs) are cell‐derived membrane vesicles that are released into the extracellular space. EVs encapsulate key proteins and mediate intercellular signalling pathways. Recently, primary cilia have been shown to release EVs under fluid‐shear flow, but many proteins encapsulated in these vesicles have never been identified. Primary cilia are ubiquitous mechanosensory organelles that protrude from the apical surface of almost all human cells. Primary cilia also serve as compartments for signalling pathways, and their defects have been associated with a wide range of human genetic diseases called ciliopathies. To better understand the mechanism of ciliopathies, it is imperative to know …

Suppression Of Human Coronavirus 229e Infection In Lung Fibroblast Cells Via Rna Interference, Hamidreza Montazeri Aliabadi, Jennifer Totonchy, Parvin Mahdipoor, Keykavous Parang, Hasan Uludağ

Pharmacy Faculty Articles and Research

Despite extensive efforts to repurpose approved drugs, discover new small molecules, and develop vaccines, COVID-19 pandemic is still claiming victims around the world. The current arsenal of antiviral compounds did not perform well in the past viral infections (e.g., SARS), which casts a shadow of doubt for use against the new SARS-CoV-2. Vaccines should offer the ultimate protection; however, there is limited information about the longevity of the generated immunity and the protection against possible mutations. This study uses Human Coronavirus 229E as a model coronavirus to test the hypothesis that effective delivery of virus-specific siRNAs to infected cells will …

Thyroid Hormone Synthesis Continues Despite Biallelic Thyroglobulin Mutation With Cell Death, Xiaohan Zhang, Aaron P. Kellogg, Cintia E. Citterio, Hao Zhang, Dennis Larkin, Yoshiaki Morishita, Héctor M. Targovnik, Viviana A. Balbi, Peter Arvan

Pharmacy Faculty Articles and Research

Complete absence of thyroid hormone is incompatible with life in vertebrates. Thyroxine is synthesized within thyroid follicles upon iodination of thyroglobulin conveyed from the endoplasmic reticulum (ER), via the Golgi complex, to the extracellular follicular lumen. In congenital hypothyroidism from biallelic thyroglobulin mutation, thyroglobulin is misfolded and cannot advance from the ER, eliminating its secretion and triggering ER stress. Nevertheless, untreated patients somehow continue to synthesize sufficient thyroxine to yield measurable serum levels that sustain life. Here, we demonstrate that TGW2346R/W2346R humans, TGcog/cog mice, and TGrdw/rdw rats exhibited no detectable ER export of thyroglobulin, accompanied by severe …

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 …

Synthesis And Characterization Of Antiviral Drug Candidate Molecules Against The Respiratory Syncytial Virus, Ali Abbas Sabi

Dissertations

Abstract

Pyrrole-imidazole polyamides (PAs) are small molecules that typically develop H-bonds to bind to the minor groove of DNA. PAs are of interest because they can be designed to recognize DNA sequences. PAs have numerous biomedical applications in areas like regulation of gene expression and antimicrobial activity. Specifically, polyamide UMSL1011 (a polyamide synthesized in Dr. Bashkin's lab) inhibits replicating vesicular stomatitis virus (VSV) by binding the viral RNA inside the nucleocapsid, as indicated by research at Professor Ming Luo's lab at Georgia State University. However, some reports have revealed that polyamides have a low affinity for “simple” double-stranded RNA. Nevertheless, …

Nmr Solution Structures Of Runella Slithyformis Rna 2'-Phosphotransferase Tpt1 Provide Insights Into Nad+ Binding And Specificity, Sébastien Alphonse, Ankan Banerjee, Swathi Dantuluri, Stewart Shuman, Ranajeet Ghose

Publications and Research

Tpt1, an essential component of the fungal and plant tRNA splicing machinery, catalyzes transfer of an internal RNA 2′-PO₄ to NAD⁺ yielding RNA 2′-OH and ADP-ribose-1′,2′-cyclic phosphate products. Here, we report NMR structures of the Tpt1 ortholog from the bacterium Runella slithyformis (RslTpt1), as apoenzyme and bound to NAD⁺. RslTpt1 consists of N- and C-terminal lobes with substantial inter-lobe dynamics in the free and NAD⁺-bound states. ITC measurements of RslTpt1 binding to NAD⁺ (K_D ∼31 μM), ADP-ribose (∼96 μM) and ADP (∼123 μM) indicate that substrate affinity is determined primarily by …

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 …
