Perinatal Inflammation And Oxidative Stress Alter Adult Rat (Rattus Norvegicus) Motor Behavior, Alexander Young

Honors College Theses

Recent evidence in comparative animal models suggests that early life exposure to elevated inflammation (via LPS exposure) and oxidative stress (via acetaminophen exposure) may synergistically interact to alter typical neurodevelopmental trajectories, resulting in lasting effects on both behavior and gut-brain neurochemistry. The current study observed emotional and motor behaviors and collected fecal-boli to measure Tyrosine (TE) levels in male and female Long-Evans (Rattus norvegicus) rats. Subjects were either treated with [1] saline [2] lipopolysaccharide (LPS) to introduce an inflammatory state, [3] acetaminophen (APAP) to introduce oxidative stress, or [4] a dual-hit of both LPS + APAP on postnatal day (PD) …

Effects Of Dietary Perfluorobutane Sulfonate (Pfbs) On Adipose Tissue, Hannah Olofintuyi, Eric Gato

Honors College Theses

Per- and polyfluoroalkyl substances (PFAS) are chemical substances used in a variety of industrial applications and consumer products. Perfluorobutane sulfonate (PFBS) is often used as a replacement for the more harmful (Perfluoroalkyl sulfonate) PFAS chemicals that have been around longer. It is believed that PFBS does not remain in the body as long as other PFAS compounds; however, there is a rising concern that it has the potential to cause damage to human health. This study focused on understanding how dietary PFBS exposure affects metabolism-related processes in adipose tissues in rats. To accomplish study objectives, Sprague Dawley rats were exposed …

Enhancing Cataract Surgery Outcomes: Optimal Use Of Pre- And Post-Operative Eye Drops, Keith Skolnick M.D., Anu Valiaveedu

Mako: NSU Undergraduate Student Journal

Many preoperative and postoperative cataract patients struggle with comprehending the use of prescription medication as directed. Language barriers and low health literacy levels are major factors contributing to improper use of prescriptions. To increase patients comprehension, the Fort Lauderdale Eye Institute employed an educational intervention consisting of a live presentation and an instructional video. Results found that 44% of patients were hesitant to ask questions to clinical staff, 32% felt overwhelmed, and nearly 70% lacked confidence in using their prescribed eye drops. Following the intervention, 91% of patients reported increased confidence in their medications, and most indicated that the video …

Determining The Bioaccumulation Of Minor Cannabinoids In Zebrafish Larvae, Kamdyn A. Holt

Honors Theses

Due to the increasing prevalence of cannabis product availability and usage in the modern United States, particularly among pregnant individuals, evaluating the bioaccumulation of minor cannabinoids to further understand the adverse effects of cannabinoids during early development is critical. This study quantitated the uptake of eight minor cannabinoids ((∆8-tetrahydrocannabinol (∆8-THC), ∆9-THC, ∆10-THC, cannabidiol (CBD), cannabigerol (CBG), cannabinol (CBN), tetrahydrocannabivarin (THCV), and hexahydrocannabinol (HHC)) in zebrafish larvae following water-borne 2 µM exposures from 6 to 96 hours post fertilization (hpf). Larvae were homogenized at 96 hpf and analyzed using a gas chromatography- mass spectrometry (GC-MS) method developed in this study. Bioconcentration …

5-Fluorouracil Induced Oxidative Stress Is Variable Across Triple Negative Breast Cancer Cell Lines, Rachel L. Walker

Departmental Honors & Graduate Capstone Projects

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with treatment limited to chemotherapy. However, not all patient tumors respond to chemotherapy. The variable cytotoxic effects of chemotherapies may be due to how cancer cells regulate reactive oxygen species (ROS). In this study, we examined two mouse breast cancer cell lines: 4T1 and EO771, vary when treated with hydrogen peroxide (H2O2) and 5-Fluorouracil (5FU), known ROS-inducing substances. In 4T1 cells H2O2 increased oxidized DNA but caused minimal cell death. While in EO771 cells that same amount of H2O2 caused complete apoptosis. Cell number, ROS, and cell death showed …

Calcium Carbonate As A Potential Intervention To Prevent Labor Dystocia: Narrative Review Of The Literature, Sabahat Raees, Marie Forgie, Rita Mitchell, Emily Malloy

Journal of Patient-Centered Research and Reviews

Anecdotally, there are attestations from clinicians of calcium carbonate being used successfully for laboring people experiencing labor dystocia. The goal of this narrative review was to provide a synopsis of pertinent literature on calcium use in obstetrics to explore the potential benefit of calcium carbonate as a simple and low-cost intervention for prevention or treatment of labor dystocia. To answer how calcium and carbonate physiologically contribute to myometrium contractility, we conducted a literature search of English-language peer-reviewed articles, with no year limitation, consisting of the keywords “calcium,” “calcium carbonate,” “calcium gluconate,” “pregnancy,” “hemorrhage,” and variations of “smooth muscle contractility” and …

Omarigliptin Attenuates Rotenone-Induced Parkinson's Disease In Rats: Possible Role Of Oxidative Stress, Endoplasmic Reticulum Stress And Immune Modulation, Shereen Mowaka, Haidy E. Michel, Mariam M. Tadros, Moataz S. Hendy, Bassam M. Ayoub

Pharmacy

The current study aimed to explore the potential neuroprotective effect of omarigliptin (OG), an antidiabetic drug that crosses the blood-brain barrier (BBB), in a Parkinson's disease (PD) rotenone-based rat-model. Results showed that OG attenuated motor impairment, histological aberrations, α-synuclein accumulation, and rescued the dopaminergic neurons in rotenone-administered rats. Furthermore, OG halted rotenone-induced oxidative stress; as shown by reduced lipid peroxidation, decline in the oxidative stress sensor (nuclear factor erythroid 2-related factor 2) and its downstream heme oxygenase-1. In addition, OG abrogated neuroinflammation and apoptosis in rotenone-treated rats. Moreover, OG ameliorated endoplasmic reticulum (ER) stress in rotenone-administered rats; as evidenced by …

Comparison Of Free Versus Encapsulated Drugs On 3t3 Differentiation, Simon H. Friedrich, Gabriel Volpe

UROP Posters

The scope of this project was to design, synthesize and test targeted nanoparticles containing hydrophobic and hydrophilic drugs that promote browning in adipose tissue. For hydrophilic drugs the use of liposomes and their hydrophilic core is more useful than the PLGA nanoparticles which have hydrophobic cores. The inhibition of the FOXO1 pathway and modulation of autophagy in adipose tissue can promote browning of white adipose tissue, or an energy burning state where excess energy is burned as heat instead of stored in the cell. If successful, these drugs would offer an alternative treatment for obesity where changes to the patient's …

Comparative Metabolism Of Aflatoxin B1 In Two Quail Genera Coturnix Japonica And Callipepla Californica, Sean Moody

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Avian species are highly susceptible to the hepatotoxic mycotoxin aflatoxin B₁ (AFB₁). Domesticated turkeys are exquisitely sensitive, due to a combination of highly-efficient hepatic cytochrome P450 (CYP)-mediated bioactivation, and to dysfunctional alpha-class glutathione S-transferases (GSTAs) which typically detoxify the bioactivated electrophilic metabolite exo-AFB₁-8,9-epoxide (AFBO). Wild turkeys are relatively resistant to AFB₁ in large part due to expression of functional GSTAs. Quail, a related Galliforme, are slightly less sensitive in vivo to AFB₁, but whether this is related to the hepatic metabolic profiles of these two critical enzymes has not been rigorously evaluated. …

Background and Aims: Dietary gangliosides are present in human milk and consumed in low amounts from organ meats. Clinical and animal studies indicate that dietary gangliosides attenuate signaling processes that are a hallmark of inflammatory bowel disease (IBD). Gangliosides decrease pro-inflammatory markers, improve intestinal permeability, and reduce symptoms characteristic in patients with IBD. The objective of this study was to examine mechanisms by which dietary gangliosides exert beneficial effects on intestinal health.

Methods: Studies were conducted in vitro using CaCo-2 intestinal epithelial cells. Gangliosides were extracted from milk powder and incubated with differentiated CaCo-2 cells after exposure to pro-inflammatory stimuli. …

The Comorbidity Of Drug And Alcohol Consumption In Relation To Mental Health Disorders, Sydney Dawson

Intuition: The BYU Undergraduate Journal of Psychology

The constantly increasing use of drugs and alcohol in young adults has created great controversy in the medical community on the long-term effects of these substances. The average brain development of adolescence and young adults is not complete until the age of 25, though drug and alcohol intake occur across the United States at younger ages each year. Impulsive behavior and underdeveloped neural pathways create a strong pull for addiction formulations and the development of severe mental-health problems. This paper reviews the positive and negative effects of illicit drugs and alcohol intake and their comorbidity with mental health disorders. There …

How Can We Stop Cancer?, Joseph R. Current

The Review: A Journal of Undergraduate Student Research

Cancer is a disease that humans have been struggling to combat for centuries. It originates from the accumulation of several mutations over the life of a cell that causes it to evade cell death and multiply rapidly. It can affect any tissue in the body and can spread to other parts of the body through metastasis. Cancer comes in numerous shapes and sizes with different levels of aggression, growth speeds, and health risks. Many treatments for cancer exist today, three of the most popular being surgery, chemotherapy, and radiation therapy, which can be used in combinations with other treatments to …

Accordingly, there is an urgent demand to create novel effective therapeutic drugs that can inhibit biofilm formation with new mechanisms of action to surmount the current escalating resistance. In this study, in silico hybrid model was utilized to develop three novel short linear peptides (4, 5, and 6) with potential biofilm inhibiting activities (scores > 1.0). The peptides were composed of cationic and hydrophobic residues. They were synthesized using solid-phase strategy. Synthesized peptides were purified and …

Polyrotaxane Variants And Their Effects On The Cholesterol Efflux In Patients Suffering From Niemann Pick Type C, Sydney Smith, Zach Struzik, David Thompson

The Summer Undergraduate Research Fellowship (SURF) Symposium

Niemann Pick type C disease (NPC) is a rare lysosomal storage disorder characterized by a progressive accumulation of cholesterol in the late endosomal/lysosomes compartment leading to cellular dysfunction and organ failure. Symptoms include ataxia, dysarthria, cognitive dysfunction, and seizures. Although average life expectancy is below 20, there are no FDA approved treatment available making it a serious unmet medical need. Clinical trials with 2-hydroxypropyl-beta-cyclodextrin (HP-beta-CD) has shown promise in cholesterol normalization within NPC cells. However, HP-beta-CD treatment has been shown to cause ototoxicity in NPC patients at high dosages. Supramolecular complexes known as polyrotaxanes have been synthesized in hopes of …

A V-To-F Substitution In Sk2 Channels Causes Ca2+ Hypersensitivity And Improves Locomotion In A C. Elegans Als Model, Young-Woo Nam, Sabia N. Baskoylu, Dimitris Gazgalis, Razan Orfali, Meng Cui, Anne C. Hart, Miao Zhang

Pharmacy Faculty Articles and Research

Small-conductance Ca2+-activated K+ (SK) channels mediate medium afterhyperpolarization in the neurons and play a key role in the regulation of neuronal excitability. SK channels are potential drug targets for ataxia and Amyotrophic Lateral Sclerosis (ALS). SK channels are activated exclusively by the Ca2+-bound calmodulin. Previously, we identified an intrinsically disordered fragment that is essential for the mechanical coupling between Ca2+/calmodulin binding and channel opening. Here, we report that substitution of a valine to phenylalanine (V407F) in the intrinsically disordered fragment caused a ~6 fold increase in the Ca2+ sensitivity of SK2-a channels. This substitution resulted in a novel interaction between …

Clearance Concepts: Fundamentals And Application To Pharmacokinetic Behavior Of Drugs, Reza Mehvar

Pharmacy Faculty Articles and Research

Clearance concepts were introduced into the pharmacokinetics discipline in the 1970s and since then have played a major role in characterization of the pharmacokinetic behavior of drugs. These concepts are based on the relationship between organ extraction ratio or clearance and physiologic parameters such as the organ blood flow and the intrinsic capability of the eliminating organ to remove the free (unbound) drug from the body. Several theoretical models have been developed, which define these relationships and may be used to predict the effects of changes in the physiological parameters on various pharmacokinetic parameters of drugs, such as drug clearance. …

A Review Of Ankylosing Spondylitis, Hannah L. Owen

Senior Honors Theses

Ankylosing spondylitis (AS) is a systemic autoimmune disorder that induces ankylosis of the spine (fusion of the vertebrae at their various joints) and inflammatory arthritis of peripheral joints among other symptoms. Overexpression of cytokines, the presence of genetic mutations not exclusive to the human leucocyte antigen (HLA)-B27 region, and environmental factors all have large roles in the progressive development of AS. Although a definitive pathology continues to be sought after, researchers believe the adaptive immune system in AS patients attacks fibrocartilaginous entheses (supportive connective tissue between bone and attached structures like tendon, ligament, and fascia).

AS markedly reduces proper systemic …

The Effects Of Tranexamic Acid On Mortality Rate In Trauma Patients Compared To Trauma Patients With No Tranexamic Acid Treatment, Bradley Earl Tolar

Production Of Recombinant Human Coagulation Factor Ix By Transgenic Pig, Weijie Xu

Department of Chemical and Biomolecular Engineering: Dissertations, Theses, and Student Research

Hemophilia B is the congenital bleeding disorder caused by deficiency in functional coagulation factor IX (FIX) and about 28,000 patients worldwide in 2012. And current treatment is restricted to protein-replacement therapy, which required FIX concentrates for patients’ life-time. Approximately 1 billion units FIX were consumed in 2012. However, still about 70-80% patients, mostly in developing countries, received inadequate or no treatment because of the unavailable and/or unaffordable FIX concentrates. Considering safety reasons, e.g. transmission of blood-borne diseases, the recombinant human FIX (rFIX) is recommended other than the plasma-derived FIX. However, only one rFIX is currently available on the market. The …

Characterization Of Extraction Methods To Recover Phenolic-Rich Antioxidants From Blue Green Algae (Spirulina) Using Response Surface Approaches, Ahmad Salamatullah

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Blue green algae (spirulina) is a dietary system that is widely consumed as a whole food or as a supplement in many Asian countries where populations are mostly unaffected by many of the diseases currently afflicting western societies, such as cancer, heart disease and arthiritis. Indeed, spirulina is a rich source of antioxidants with the phenolic compounds playing a significant role. As components of a complex dietary system, phenolic compounds can act alone or through synergistic mechanisms to impart a greater biologic effect than can be elicited by a sum of the individual parts. Therefore, an understanding of the antioxidative …
