Proposing An Rna Interference (Rnai)-Based Treatment For Human Immunodeficiency Virus (Hiv) By Analyzing The Post-Transcriptional Gene Targeting Of Sars-Cov-2, Hepatitis C Virus, And A549 Lung Cancer Cells, Arjun Jagdeesh

Undergraduate Research Posters

Human Immunodeficiency Virus (HIV) is a retrovirus that infects CD4+ T cell lymphocytes in humans, leading to the development of Acquired Immunodeficiency Syndrome (AIDS) if left untreated. While current treatment methods, including antiretroviral combination treatments, effectively limit HIV replication, HIV can evade these treatments due to its high mutation rate. Long-term antiretroviral treatment can also be toxic to patients, meaning patients would benefit from a new mechanism of HIV treatment. RNA interference (RNAi) is an antiviral pathway found in mammals, plants, and insects that involves a small-interfering RNA that is incorporated into a protein complex called the RNA-induced Silencing Complex …

Therapies For Mitochondrial Disorders, Kayli Sousa Smyth, Anne Mulvihill

SURE Journal: Science Undergraduate Research Experience Journal

Mitochondria are cytoplasmic, double-membrane organelles that synthesise adenosine triphosphate (ATP). Mitochondria contain their own genome, mitochondrial DNA (mtDNA), which is maternally inherited from the oocyte. Mitochondrial proteins are encoded by either nuclear DNA (nDNA) or mtDNA, and both code for proteins forming the mitochondrial oxidative phosphorylation (OXPHOS) complexes of the respiratory chain. These complexes form a chain that allows the passage of electrons down the electron transport chain (ETC) through a proton motive force, creating ATP from adenosine diphosphate (ADP). This study aims to explore current and prospective therapies for mitochondrial disorders (MTDS). MTDS are clinical syndromes coupled with abnormalities …

While the COVID-19 pandemic disrupted healthcare delivery everywhere, persons with carceral system involvement and opioid use disorder (OUD) were disproportionately impacted and vulnerable to severe COVID-associated illness. Carceral settings and community treatment programs (CTPs) rapidly developed protocols to sustain healthcare delivery while reducing risk of COVID-19 transmission. This survey study assessed changes to OUD treatment, telemedicine use, and re-entry support services among carceral and CTPs participating in the National Institute on Drug Abuse (NIDA)-funded study, Long-Acting Buprenorphine vs. Naltrexone Opioid Treatments in Criminal Justice System-Involved Adults (EXIT-CJS) study. In December 2020, carceral sites (n = 6; median pre-COVID 2020 …

High Anxiety In Pediatric Oncology Patients? What About Art Therapy?, Rebekah Love

Symposium of Student Scholars

Anxiety and depression are becoming more prevalent in the pediatric population today. In addition to the general pediatric population experiencing an increased risk of mental illness, children with an oncology related diagnosis have an even heightened risk. Most pediatric oncology patients reported fear or worry daily, which is cited to be most severe when they had an appointment or went to the hospital for a fever. It is imperative we discover interventions to lessen the anxiety and depression pediatric oncology patients experience daily. A literature review revealed conclusive interventions have not been determined. The purpose of this research is to …

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 …

Effects And Outcomes Of Different Laboring Positions And The Influence From Societal Norms, Amberlyn Heskett

Nursing | Senior Theses

Background

Within labor and delivery, every birth is different. Alarmingly, the U.S. has the highest maternal mortality rate, including death during labor, among developed countries (World Health Organization, 2022). Many maternal deaths may be preventable.

In the U.S., the use of forceps, vacuum-assisted birth, episiotomies, and emergency C-sections are common for women during childbirth. Even though some laboring positions may assist birthing more than others, there often is resistance to allowing various positions due to outside influences, including societal norms, hospital management, and healthcare professional training. Women in labor are vulnerable and look to their nurses for support during the …

Psychedelic Forum Member Preferences For Carer Experience And Consumption Behavior: Can “Trip Sitters” Help Inform Psychedelic Harm Reduction Services?, Liam B. Engel, Sascha B. Thal, Stephen J. Bright

Research outputs 2022 to 2026

Background: There is limited research on the provision of harm reduction services to people who use psychedelics. Little is known about provision of care to people consuming psychedelics outside of clinical trials.

Methods: We investigated how people who used psychedelics discussed their preferences for care (or “trip sitting”) on two online forums: The Shroomery and DMT Nexus. A thematic analysis of the discussion was conducted to better understand consumer preferences for harm reduction services and resources.

Conclusion: Demand for trip sitters with lived psychedelic experience is likely influenced by stigma and empathy. Trip sitters who could relate to the effects …

Successful Buprenorphine Transition While Overlapping With A Full Opioid Agonist To Treat Chronic Pain: A Case Report, Kishan V. Patel, Sidharth Sahni, Lanvin F. Taylor

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Buprenorphine is a partial mu opioid agonist that has been increasingly utilized to treat patients with chronic pain and opioid use disorder (OUD). The drug has proven to provide significant chronic pain relief at low doses ranging from 75 to 1800 mcg. The conventional buprenorphine transitional process delays its introduction until patients begin withdrawal. However, this process can pose a barrier to both patients and providers due to some patients' inability to tolerate traditional prerequisite withdrawal. To our knowledge, this is a rare reported case to describe a transitional process utilizing buccal buprenorphine in which a patient with chronic pain …

Macrodosing To Microdosing With Psychedelics: Clinical, Social, And Cultural Perspectives, Ayse Ceren Kaypak, Amir Raz

Psychology Faculty Articles and Research

To date, the clinical and scientific literature has best documented the effects of classical psychedelics, such as lysergic acid diethylamide (LSD), psilocybin, and dimethyltryptamine (DMT), in typical quantities most often associated with macrodosing. More recently, however, microdosing with psychedelics has emerged as a social trend and nascent therapeutic intervention. This variation in psychedelic practice refers to repeat, intermittent ingestion of less-than-macrodose amounts that do not cause the effects associated with full-blown “trips”. Microdosing paves the road to incorporating psychedelic drugs into a daily routine while maintaining, or even improving, cognitive and mental function. Unlike macrodosing with psychedelics, the influence of …

Efficacy Of Various Interventions For Achieving Target Hba1c Levels For Patients With Type Ii Diabetes Mellitus And On Exogenous Insulin, Caitlin S. Welch, Archie Troxel

Longitudinal Scholar's Project

Objective: To learn the rates at which patients at UT Family Medicine–St. Francis (UTFM–SF) with type II diabetes mellitus are being prescribed recommended medications—namely metformin, sodium-glucose cotransporter 2 (SGLT2) inhibitors, and glucagon-like peptide 1 receptor agonists (GLP1RAs)—whether these rates correspond to the severity of hyperglycemia (as indicated by HbA1C level). A secondary goal of the study was to investigate if HbA1C levels are being checked at recommended intervals.

Methods: A retrospective chart review was conducted using records of patients seen at the clinic in the previous four years between the ages of 18 and 65 who had visits with ICD …

A Multicenter Weighted Lottery To Equitably Allocate Scarce Covid-19 Therapeutics, Douglas B. White, Erin K. Mccreary, Chung-Chou H. Chang, Mark Schmidhoffer, J. Ryan Bariola, Naudia N. Jonassaint, Govind C. Persad, Robert D. Truog, Parag A. Pathak, Tayfun Sönmez, M. Utku Unver

Sturm College of Law: Faculty Scholarship

Shortages of new therapeutics to treat coronavirus disease (COVID-19) have forced clinicians, public health officials, and health systems to grapple with difficult questions about how to fairly allocate potentially life-saving treatments when there are not enough for all patients in need. Shortages have occurred with remdesivir, tocilizumab, monoclonal antibodies, and the oralantiviral Paxlovid.

Ensuring equitable allocation is especially important in light of the disproportionate burden experienced during the COVID-19 pandemic by disadvantaged groups, including Black, Hispanic/Latino and Indigenous communities, individuals with certain disabilities, and low-income persons. However, many health systems have resorted to first-come, first-served approaches to allocation, which tend …

Ribonucleotide Reductase Subunit Switching In Hepatoblastoma Drug Response And Relapse, Anthony Brown

Theses and Dissertations (ETD)

Hepatoblastoma is the most common primary liver cancer in infants and young children. Despite being a very rare cancer that accounts for only 0.5-2% if all childhood cancer cases, HB has the largest increase in incidence among childhood cancers in the United States and worldwide. The five-year survival rate of children with the aggressive forms of HB, including those that have developed metastatic or recurrent diseases, is less than 40% due to the lack of effective treatment. We aim to identify targetable mechanisms underlying the progression and drug resistance of high-risk HB. Our recent work on HB mouse and organoid …

Nursing Perspectives And Opinions On Early Or Delayed Sepsis Treatment: A Mixed Methods Approach, Pamela L. Harris

Theses and Dissertations (ETD)

Purpose. Each year at least 1.7 million adults in America develop sepsis. Sepsis can lead to life threatening organ dysfunction, severe hypotension, and death when severe sepsis or septic shock is involved. Sepsis is responsible for 50% of acute kidney injury (AKI), which is the most common form of organ dysfunction seen in critical care. Sepsis associated AKI results in loss of, or decreased renal function, is associated with adverse long-term outcomes, and carries a higher mortality rate than non-septic AKI, sepsis without AKI, or septic shock without AKI. Surviving sepsis guidelines suggests a 1-hour window from the time of …

Roles Of Oxidative Stress And Dna Methylation In Cigarette Smoking-Induced Accelerated Acute Myeloid Leukemia Progression, Mary Figueroa

Dissertations and Theses (Open Access)

Acute myeloid leukemia (AML) is a commonly diagnosed cancer in smokers. When current or former smokers have AML, they have worse survival compared to never smoking patients. This has been observed clinically for decades, but then it is unknown how smoking leads to worsened AML survival. Smoking causes oxidative stress and altered DNA methylation that persists for decades in peripheral blood mononuclear cells, but these changes from smoking have not been evaluated in the context of AML. We hypothesize that smoking-induced molecular changes, including altered DNA methylation associated with poor AML prognosis, promote AML. We developed a novel model to …

Radioluminescence Based Biochemical Sensing And Imaging Strategies To Measure Local Drug Release And Ph, Gretchen B. Schober

All Dissertations

In this dissertation we describe methods for measuring infection relevant biochemical analytes using radioluminescent and ultrasound luminescent materials. Films and nanoparticles fabricated with europium doped gadolinium oxysulfide (Gd₂O₂S:Eu³⁺) are used to quantitatively measure radiolabeled pharmaceutical concentration, specifically tritium labeled vancomycin (³H-vancomycin). Europium and dysprosium doped strontium aluminate is used to fabricate an ultrasound modulated, pH sensing film. These methods are indicated for theranostic evaluation of implant associated infection. Bacterial biofilms are inherently resistant to traditional antibiotic treatment and can coat biomedical implants. These biofilm related infections are difficult or impossible to eradicate …

Introduction

Previously irradiated tissue is characterized by changes including decreased vascularity, impaired cellular proliferation, and local hypoxia consistent with fibroblastic atrophy which can persist long after radiation therapy. Hyperbaric oxygen therapy has been shown to be beneficial in the treatment of complications arising from these late effects of radiation on normal tissue through enhancing fibroblast proliferation, collagen maturation, stem cell recruitment, and angiogenesis.

Methods

We report on three patients with debilitating radiation enterocolitis causing issues including recurrent bowel obstruction, anorexia requiring total parenteral nutrition, pain, diarrhea, fecal incontinence, dehydration, and malnutrition.

Results

In all three cases marked improvement was the …

Hyperbaric Oxygen Therapy For Cerebral Radiation Necrosis Secondary To Stereotactic Radiation: A Case Series, Sruti Prathivadhi-Bhayankaram, Jeffrey S. Cooper

Graduate Medical Education Research Journal

Introduction: Stereotactic radiosurgery (SRS) is an excellent option for the treatment of numerous central nervous system diseases. There exist several forms of SRS, including gamma-knife surgery (GKS) and cyber-knife surgery. The most significant complication of SRS is the delayed effects of therapeutic radiation, also known as radionecrosis. The current treatment options for radionecrosis have a significant side effect profile and posit challenges for medical management. More recently, hyperbaric oxygen therapy (HBO2) has emerged as an option for treatment with minimal side effects.

Methods: We present a retrospective case series examining ten patients treated with HBO2 after receiving radiotherapy. Of …

Otulin's Novel Regulatory Mechanisms In Genotoxic And Inflammatory Nf-Kb Signaling, Mingqi Li

Theses and Dissertations (ETD)

Triple negative breast cancer (TNBC) is aggressive but cannot be treated with hormone therapy or molecular therapy due to the lack of a target. Chemotherapy is a systemic treatment that works by attacking rapidly growing cells, which is initially more effective for TNBC patients than those individuals with the hormone receptor-positive breast cancer. However, patients with TNBC tend to develop resistance to chemo drugs, called chemoresistance. After years of effort, the signaling pathways involved in TNBC chemoresistance are gradually revealed, including the nuclear factor-kappa B (NF-kB) pathway. Transcription factor NF-kB is widely involved in cancer development and progression, and its …

Targeting Myeloid Protein Kinase C Signaling To Overcome Immune Suppression And Improve Immunotherapy In Cancer, Mehdi Chaib

Theses and Dissertations (ETD)

Checkpoint immunotherapy unleashes T cell antitumor potential which has revolutionized cancer treatment showing unprecedented long-term responses. However, most patients do not respond to immunotherapy which often correlates with a dysfunctional or immunosuppressive myeloid compartment. Immunosuppressive myeloid cells comprise Myeloid-derived suppressor cells (MDSCs) and tumor-associated macrophages (TAMs) and can suppress T cells via production of immunosuppressive factors. Conversely, efficient cytotoxic T cell priming is dependent on the ability of antigen-presenting cells (APCs), mainly conventional dendritic cells (cDCs) and macrophages, to present or cross-present tumor antigens to T cells. Thus, targeting immunosuppressive myeloid cells while simultaneously enhancing APCs represents a promising strategy …

Angiogenin Released From Abcb5+ Stromal Precursors Improves Healing Of Diabetic Wounds By Promoting Angiogenesis, Karmveer Singh, Pallab Maity, Albert Kallon Koroma, Abhijit Basu, Rajeev Kumar Pandey, Seppe Vander Beken, Philipp Haas, Linda Krug, Adelheid Hainzl, Anca Sindrilaru, Christiane Pfeiffer, Meinhard Wlaschek, Natasha Y. Frank, Markus H. Frank, Christoph Ganss, András Bánvölgyi, Norbert Wikonkál, Sabine Eming, Irena Pastar, Marjana Tomic-Canic, Mark A. Kluth, Karin Scharffetter-Kochanek

Research outputs 2022 to 2026

Severe angiopathy is a major driver for diabetes-associated secondary complications. Knowledge on the underlying mechanisms essential for advanced therapies to attenuate these pathologies is limited. Injection of ABCB5+ stromal precursors at the edge of nonhealing diabetic wounds in a murine db/db model, closely mirroring human type 2 diabetes, profoundly accelerates wound closure. Strikingly, enhanced angiogenesis was substantially enforced by the release of the ribonuclease angiogenin from ABCB5+ stromal precursors. This compensates for the profoundly reduced angiogenin expression in nontreated murine chronic diabetic wounds. Silencing of angiogenin in ABCB5+ stromal precursors before injection significantly reduced angiogenesis and delayed wound closure in …
