Mindfulness Meditation As A Complementary Therapy For Chronic Migraines, Isaac Min, Manjari Murali

Student Scholar Symposium Abstracts and Posters

Migraine headaches, the most common neurological disease across all age groups, affect over one billion individuals worldwide, with symptoms ranging from moderate to severe. Migraines differ in intensity and are accompanied by secondary symptoms, such as neck pain, nausea, and vomiting. Current efforts in treating migraines focus on preventative drug therapy to reduce the frequency of migraine attacks. Although mindfulness-based approaches such as MBSR may serve as an alternative method of reducing the severity of migraine attacks, studies investigating the efficacy of MBSR are limited.

A meta-analysis provides insights into the pathogenesis of migraines through the identification of three genes …

In Vitro Characterization Of A Novel Murine Model Of Cancerous Progression, Steven D. Scahill, Kelly Jean Sherman, Jessie J. Guidry, Whitney Walkowski, Theresa Nguyen, Durwood B. Ray, David H. Jones, Harry J. Gould, Dennis Paul

School of Graduate Studies Faculty Publications

To evaluate a potentially valuable tool to study cancer progression and metastasis, we characterized a novel murine model composed of a parental oncogene-transformed embryonic fibroblast line and five cell lines isolated from progressively advanced tumors. Lines derived from distant metastases displayed significantly greater rates of motility, invasiveness, and extracellular acidification than lines derived from a primary tumor or local metastases. A comprehensive proteomic analysis of these cells showed numerous oncogenes to be upregulated and tumor suppressors to be downregulated in the advanced lines, and provided novel targets for future examination. The first cell line capable of extravasation displayed particularly high …

Impact Of Clonal Plasma Cells In Autografts On Outcomes In High-Risk Multiple Myeloma Patients, Oren Pasvolsky, Denái R Milton, Mikael Rauf, Sassine Ghanem, Adeel Masood, Ali H Mohamedi, Mark R Tanner, Qaiser Bashir, Samer Srour, Neeraj Saini, Paul Lin, Jeremy Ramdial, Yago Nieto, Guilin Tang, Hans C Lee, Krina K Patel, Partow Kebriaei, Sheeba K Thomas, Donna M Weber, Robert Z Orlowski, Katy Rezvani, Richard Champlin, Elizabeth J Shpall, Pei Lin, Muzaffar H Qazilbash

Most patients with multiple myeloma (MM) undergoing autologous hematopoietic stem cell transplantation (autoHCT) eventually relapse, perhaps due to the presence of clonal plasma cells (CPC) in the autograft. We conducted a retrospective analysis to evaluate the impact of CPC in the autograft on the outcomes of high-risk chromosomal abnormalities (HRMM) patients undergoing autoHCT between 2008 and 2018. Patients were divided into CPC+ or CPC- in the autograft by next-generation flow cytometry (NGF). There were 75 CPC + autografts (18%) and 341 CPC- (82%). The CPC + group was less likely to achieve MRD-negative complete remission post-transplant (11% vs. 42%; p < 0.001). Median progression free survival (PFS) and overall survival (OS) were (12.8 vs. 32.1 months) and (36.4 vs. 81.2 months) in the CPC + and CPC- groups, respectively (both p < 0.001). Also in the subset of patients with MRD-negative ≥VGPR prior to autoHCT, those with CPC + autografts had inferior PFS (HR 4.21, p = 0.006) and OS (HR 7.04, p = 0.002) compared to CPC-. In multivariable analysis, the degree of CPC positivity in the autograft was independently predictive of worse PFS (HR 1.50, p = 0.001) and OS (HR 1.37, p = 0.001). In conclusion, both the presence and degree of CPC in the autograft were highly predictive of inferior PFS and OS.

Background

Homozygous familial hypercholesterolemia (HoFH) is a rare, treatment‐resistant disorder characterized by early‐onset atherosclerotic and aortic valvular cardiovascular disease if left untreated. Contemporary information on HoFH in the United States is lacking, and the extent of underdiagnosis and undertreatment is uncertain.

Methods and Results

Data were analyzed from 67 children and adults with clinically diagnosed HoFH from the CASCADE (Cascade Screening for Awareness and Detection) FH Registry. Genetic diagnosis was confirmed in 43 patients. We used the clinical characteristics of genetically confirmed patients with HoFH to query the Family Heart Database, a US anonymized payer health database, to estimate the …

Tcf4 Is A Key Mediator Of Cell Identity And Oncogenesis In Neuroblastoma, Nour Aljouda

Theses and Dissertations (ETD)

Neuroblastomas (NB) are embryonal childhood tumors that derive from the multipotent neural crest cells (NCCs) of the peripheral nervous system. NB accounts for more than 15% of all childhood cancer-related deaths. Despite the most intensive multimodal therapy, more than 50% of patients with high-risk NB relapse with often fatal, resistant disease. Novel therapies are desperately needed to improve cure rates. Previous studies proposed that the deregulation of normal neural crest developmental programs contributes to NB oncogenesis by retaining the highly migratory and proliferative traits of NCCs. Thus, activation or repression of neural crest developmental pathways have been implicated in NB …

The Role Of Cytochrome P450 2e1 In Hepatic Ischemia Reperfusion Injury And Reactive Oxygen Species Formation, Nouf Alwadei

Pharmaceutical Sciences (PhD) Dissertations

The mechanisms of hepatic ischemia/reperfusion (I/R) injury, which occurs during liver transplantation or surgery, are poorly understood. The central pathophysiological phenomenon of this injury is the formation of reactive oxygen species (ROS). Recent studies suggest that P450 enzymes may contribute to ROS generation, which may occur through their uncoupling and/or release of heme and iron after their degradation. Among P450 enzymes, CYP2E1 is unique because it is considered a leaky enzyme, producing significant ROS through uncoupling in the absence of substrates, accelerating its own degradation and reducing its half-life. In this dissertation, we generated and characterized a HepG2 cell line …

Immunomodulatory Effects Of Resolvin D2 In A Model Of Infection, Prem Yugandhar Kadiyam Sundarasivarao

Graduate School of Biomedical Sciences Theses and Dissertations

Dysregulated hyperinflammatory host immune response to underlying bacterial infections is a characteristic of sepsis. In sepsis, bacteria often trigger abnormal hyperinflammatory responses which can cause multiple organ failure and if sustained can lead to an immunosuppressive phase where the host is susceptible to secondary infections caused by opportunistic bacteria like Pseudomonas aeruginosa (P. aeruginosa). In our studies, we used a 2-hit model of cecal ligation and puncture (CLP) followed by P. aeruginosa secondary lung infection to investigate cellular and molecular mechanisms in the beneficial action of resolvin D2 (RvD2). Resolvins of the D-series are a group of fatty acids known …

Examining Ndufab1 Expression In Head And Neck Squamous Cell Carcinoma, Addison Stevens

Poster Presentations

Honors research poster.

Introduction: Head and neck squamous cell carcinoma (HNSCC) is approximately 4% of all cancers and 2% of all cancer associated mortality in the United States. In 2023, there will be an estimated 67,000 new cases of HNSCC, along with 15,400 deaths, in the United States. HNSCC locations include the oral cavity, oropharynx, nasopharynx, hypopharynx, and larynx. Major risk factors for HNSCC include tobacco use, alcohol use, and human papilloma virus (HPV). Epidermal growth factor receptor (EGFR) is currently the only approved molecular targeted therapy for HNSCC. Therefore, new therapeutics and biomarkers for HNSCC are warranted. Mitochondria are …

Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker

Undergraduate Honors Theses

Chronic kidney disease (CKD) progresses faster in males than females; however, the underlying mechanisms remain poorly understood. Sex differences in glomerular capillary morphology has been hypothesized to contribute, in part, to the increased susceptibility to hypertension-induced renal injury and CKD progression in males, but this has not been investigated. The goal of the present study was to assess glomerular capillary morphology in male vs. female rats with intact kidneys and after uninephrectomy (UNX). We hypothesized that glomerular capillary radii (R_CAP) and length (L_CAP) would be greater in male rats.

Male (n=4) and female (n=4) with intact …

Determining The Effects Of Maternal Adiposity On Preterm Neonatal Microbiome And Short Chain Fatty Acid Profiles, Dalton James, William A. Clark Phd, Kristy L. Thomas

Undergraduate Honors Theses

The gut microbiota and its metabolites have vast impacts on the human digestive system, immune system, and health outcomes. Short chain volatile fatty acids (SCVFAs) present in feces can be representative of the interactions of the microbiota present in the gut. Low microbiota diversity in the human gut is highly associated with obesity and adverse health outcomes. Furthermore, the maternal microbiome has a direct impact on neonatal microbiota through various pathways such as environment, skin flora, breast milk composition, and vaginal secretions. This study is aimed to further understand the associations between various factors (maternal adiposity, gestational time, length of …

An In Vivo Biocompatibility Analysis Of A Novel Tissue Regeneration Matrix Using A Pig Model, Shamar Thomas

All Theses

The goal of this project is to develop an injectable bead scaffold to promote tissue regeneration in the void created by lumpectomy and to alleviate post lumpectomy problems by preventing local recurrence and minimizing surgical-related infections. Microbeads were synthesized from collagen type I and crosslinked with tannic acid to form the basis for this injectable therapeutic. Tannic acid acts as a therapeutic anticancer agent. The action mechanisms of tannins in breast cancer cells have been studied with studies showing tannins to be cytotoxic to cancer cells in a dose-dependent manner. Tannic acid induces apoptosis in breast cancer cells via caspase …

Chemistry Faculty Publications

Background: Patients with acute alcohol-associated hepatitis (AH) have immune dysfunction. Mitochondrial function is critical for immune cell responses and regulates senescence. Clinical translational studies using complementary bioinformatics-experimental validation of mitochondrial responses were performed in peripheral blood mononuclear cells (PBMC) from patients with AH, healthy controls (HC), and heavy drinkers without evidence of liver disease (HD).
Methods: Feature extraction for differentially expressed genes (DEG) in mitochondrial components and telomere regulatory pathways from single-cell RNAseq (scRNAseq) and integrated 'pseudobulk' transcriptomics from PBMC from AH and HC (n = 4 each) were performed. After optimising isolation and processing protocols for functional studies in …

Prevalence Of Ehrlichia And Rickettsia Within Ticks In Arkansas State Parks, Haley Stanton

Animal Science Undergraduate Honors Theses

Within the past few decades, the number of diagnoses of tick-borne diseases – such as spotted fever rickettsiosis and ehrlichiosis – has steadily increased throughout the United States, with Arkansas having one of the highest rates in the country. These diseases pose a risk to both humans and animals, as both can acquire these infections from ticks. Due to the increasing geographic range of ticks, rise in cases, and likely underdiagnosis of these diseases, this study aimed to identify the infection rate of ticks themselves in multiple state parks in Arkansas. Four Arkansas state parks were each visited once a …

Special Issue: Hunger, Nutrition, And Health, Susan Rice

Journal of Food Law & Policy

Everyday millions of Americans face barriers to accessing food, housing, and other supports–––making the impossible decision of whether to put food on the table or cover other essential needs. Food insecurity and diet-related diseases, such as heart disease and diabetes, affect people of all ages and in all communities. It was for this reason that the Biden-Harris Administration hosted the White House Conference on Hunger, Nutrition, and Health in September 2022. As the President said at the Conference, “No child should go to bed hungry. No parent should die of a disease that can be prevented.” It will require all …

To address this challenge and set a course for improved nutrition and food access nationwide, the Biden-Harris Administration hosted the first White House Conference on Hunger, Nutrition, and Health in over 50 years on September 28, 2022. In the National Strategy, released in conjunction with the Conference, the Administration identified a set of actions that the federal government will take to help achieve its goal of ending hunger and increasing healthy eating and physical activity by 2030, …

A Systematic Review Of Research On Treatment & Prevention Of The Neglected Tropical Disease Leishmaniasis, Aryn Akerberg

All Theses

Leishmaniasis is a life-threatening neglected tropical disease that is caused by the protozoa parasite, Leishmania. Over one million new human leishmaniasis cases occur each all over the world, affecting most the deeply impoverished regions of the world. The disease presents in three different forms: cutaneous leishmaniasis, mucocutaneous (mucosal) leishmaniasis, and visceral leishmaniasis. Symptoms can range from self-limiting lesion to more life-threatening conditions such as fever, kidney disease, and anemia. The Leishmania parasite is transmitted via the bite of the female phlebotomine sandfly and can infect many other mammals such as canines, rodents, bats, etc. The canine leishmaniasis epidemic is also …

Implementing A Prescreening Process To Fully Assess Risk Factors And Outcomes Associated With Obesity And Hepatic Steatosis To Prevent Cirrhosis, Shana Broussard, Jennifer Eaglebarger

Doctoral Projects

Fatty liver disease can be treated if is identified in the initial stages of the disease. Once the disease progresses to fibrosis and/or cirrhosis, there is irreversible damage. The leading cause of non-alcoholic fatty liver disease is obesity. Obesity has reached epidemic proportions, with most obese individuals not fully cognizant of the repercussions of prolonged obesity. Other risk factors for fatty liver disease are uncontrolled diabetes mellitus, hyperlipidemia, and hypertension. Certain medications can also increase the risk of fatty liver disease. Currently, there is no prescreening tool to identify patients who are at risk for fatty liver disease. The researchers …

I combine a literature review with my own anecdotal experiences as an individual with Celiac’s Disease who has lived and studied in Italy. In my paper, I first describe the high awareness of gluten-free living that I noted the first time I studied abroad, being the impetus of this project. I follow this with the history and science of Celiac’s Disease for those who may be unaware of this serious chronic medical condition. I then continue to describe personal experiences I had while living in Naples, …

Introduction Of Probiotics To Improve Eczema Symptoms In Children In One Pediatric Primary Care Practice: A Quality Improvement Project, Christie Potter

Doctor of Nursing Practice Scholarly Projects

Background: There is emerging interest in alternative approaches to treating children with eczema because there is currently no allopathic cure. Non-pharmacological approaches are regarded as generally safe, well tolerated, and cost effective. Eczema is a chronic, relapsing inflammatory, itchy skin condition that adversely affects quality of life in many individuals, including children. Eczema interferes with sleep, leads to secondary skin infections, and causes intractable itching. Topical steroids are the current standard of practice in treating patients but, evidence suggests that they can cause unwanted side effects and can lead to serious systemic reactions. The purpose of this quality improvement project …

Role Of Pseudomonas Aeruginosa Exoenzymes S, T, And Y In The Modulation Of Intrinsic Apoptosis In Pulmonary Microvascular Endothelial Cells, Andrea M. Vavrinek

Honors Theses

P. aeruginosa is the most common cause of ventilator-associated pneumonia in ICU patients. P. aeruginosa uses a type III secretion system to inject exoenzymes S, T, U, and Y into host cells, exhibiting unique effects. Pulmonary microvascular endothelial cells (PMVECs) are used to evaluate cellular changes caused by exoenzymes. ExoY infection of PMVECs leads to cell rounding but does not lead to cell death, unlike ExoS/T. The current study evaluated the exoenzyme-induced modulation of intrinsic apoptosis in endothelial cells. Strain PAK, producing ExoS, T, and Y, was compared to isogenic strains expressing either S, SY, T, TY, Y, or none …

Impacts Of Dietary Restriction On A Drosophila Model Of Werner Syndrome, Eileen Sember

College of Arts & Sciences Senior Theses

Werner syndrome (WS) is an autosomal recessive disorder that results in premature aging and occurs in 1 in 1,000,0000 to 1 in 10,000,000 people. In humans, WS is the result of mutations that render the WRN gene, that contains a helicase and an exonuclease domain, non-functional. Currently, there is no cure for WS in humans, making dietary and lifestyle interventions attractive for increasing the quality and longevity of lives. Diet restriction (DR) has been shown to extend the lifespan of several model organisms, including Drosophila melanogaster, making it a strong candidate for WS treatment. In this thesis, mutant flies …

A Meta-Analysis Of The Correlation Between Historical Trauma And Health Outcomes In The Native American Population, Taylen Day

Psychological Science Undergraduate Honors Theses

Native Americans experience significant health disparities such as increased rates of
cardiovascular disease, diabetes, and mental illness. Recent research has suggested that historical trauma may be a contributing factor. This meta-analysis examined the association between historical trauma and health outcomes in Native Americans in the United States and Canada. Data from 14 studies (N = 14,698, 35 effect sizes) examining the physical health, mental health, and substance use domains and using the Historical Loss Scale were collected for analysis. Possible moderating factors were also examined. Overall, a small, significant association (r =.124) was found between historical trauma and health outcomes. …

Validating A New In Vivo Model To Study Als, Izabela J. Cimachowska

Student Theses and Dissertations

Buildup of oxidative stress and mitochondrial dysfunction are well known characteristics of both sporadic and hereditary amyotrophic lateral sclerosis (ALS). While both forms of the disease seem to arise from common cellular dysfunction, the genetic disease is studied to a much greater extent. Engineering novel animal models of the sporadic form of the disease is crucial for development of druggable targets to treat ALS and understand the underlying mechanisms. Interestingly, accumulation of oxidative stress by exacerbated emission of reactive oxygen species (ROS) from presynaptic mitochondria is a hallmark of both hereditary and sporadic ALS. Previous work by our laboratory showed …

Inhibition Of Kdm4 With Qc6352 To Target High-Risk Neuroblastoma, Ahmed M. Abuzaid

Theses and Dissertations (ETD)

Neuroblastoma (NB) is a malignancy of improperly maturated nerve tissues of the sympathetic nervous system. It is the most diagnosed extracranial solid tumor of childhood, and it accounts for roughly up to 10% of all childhood malignancies and 15% of all childhood malignancy-related deaths. MYCN amplification, occurring in 20-25% of all NB patients and 50% of all high-risk NB patients, is the well-characterized genetic abnormality and is associated with ill-fated outcomes. Regrettably, in spite of the contemporary therapeutic advances and aggressive combinatorial treatments, the overall 5-year event-free survival rate is roughly 51% with a 5-year overall survival rate of nearly …
