Regulating Neuronal Growth With Structurally Defined Glycans, Gabriella D. Hartman

Honors Theses

Chondroitin sulfate proteoglycans (CSPGs) and keratan sulfate proteoglycans (KSPGs) play an important role in neural development. Aggrecan, a CSPG, operates in the neural extracellular matrix where it negatively regulates neurite outgrowth to prevent aberrant process formation. Unfortunately, this aggrecan or CSPG-rich/KSPG-rich barrier can also prevent neuronal regeneration, which contributes to the inability to repair brain and spinal cord injuries. Removal of CSPGs and KSPGs has been shown to increase neurite outgrowth. We extend these findings by testing the ability of structurally-defined glycans to outcompete aggrecan and allow neurite outgrowth. Our overall goal is to determine if there is a particular …

Pharmacists can play a key role in preventing unintentional disqualifications of athletes as there are many medications considered performance enhancing drugs including some supplements and stimulants. For example, commonly used cold medications may contain pseudoephedrine hydrochloride, a banned substance in the world of …

Impacts Of Embryonic Exposure To Cannabidiol Or ∆9-Tetrahydrocannabinol On Zebrafish (Danio Rerio) Frailty In F0 And F1 Generations, Anika Faruque

Honors Theses

Exposure to cannabinoids during critical development periods has increased with epileptic children being commonly prescribed CBD for seizures and pregnant women taking it recreationally. Many studies have been done on the possible benefits and drawbacks of cannabinoid exposure on the human brain, but not much is known about how it can affect the developing brain long-term. To see the potential adverse effects of cannabinoid exposure during critical stages of development and discover potential developmental origins of disease in consuming cannabinoids during embryogenesis, zebrafish embryos (6-96 hours post fertilization) were exposed to varying concentrations of CBD (0.02, 0.1, 0.5 µM), THC …

Studies Of Salvinorin-Based Antagonists To Elucidate Pertinent Interactions For Kappa Opioid Receptor Antagonism, Madeline Keane

Honors Theses

Opioid abuse, leading to addiction and related deaths, has created a chronic epidemic in the United States for the past 30 years. This crisis has sprung from reliance on the prescription of opioid analgesics as the primary method for the management of pain in the 1990s. At that time, these drugs, specifically Purdue Pharma’s OxyContin, were marketed as non-addictive. Due to this systemic minimization of the addictive properties of opioid analgesics, as prescription rates increased, opioid-related mortality rates climbed. This epidemic continues to be pervasive, as opioid-related overdose resulted in 47,600 deaths in 2017. In addition to the opioid epidemic, …

Fluorometric Characterization Of A Methylene Blue Derivative Sensitive To Reactive Oxygen Species (Ros), Matthew Weeks

Honors Theses

Methylene blue (MB) has many uses within both microbiology and pharmacology. MB can treat disorders such as methemoglobinemia, malaria, Alzheimer’s disease, and certain forms of cancer. MB is also useful for molecular imaging due to its off-on fluorescent capabilities. MB derivatives with a urea bond at the 10-N position have been cleavable by triggers such as light. However, I was interested in sensitivity to reactive oxygen species (ROS). In this study, I wanted to determine if the MB derivative MB-EA exhibited sensitivity to ROS. MB-EA was exposed to varying concentrations of hydrogen peroxide and MB release was measured. I concluded …

Here, studies were performed on three catalysts, each with a nickel metal center. Each catalyst went through a series of photocatalytic tests in various conditions to identify whether a catalyst was …

Modification Of Hiv-1 Protease Inhibitor Pharmacophore To Assess Anti-Malarial Properties, Margaret Ann Street

Honors Theses

For years, the human immunodeficiency virus type 1 (HIV-1) and malarial parasites have both been prevalent in sub-Saharan Africa. Coinfections of HIV-1 and malaria are common in areas of geographic overlap as both infections seem to increase the severity of the other. HIV-1 treatments have shown to decrease the Plasmodium infections resulting in a lower malarial incidence. HIV-1 protease inhibitors target a crucial step in the life cycle required for viral maturation and have demonstrated a lower level of resistance compared with other therapies. Recent studies have shown the treatment of HIV-1 with protease inhibitors has resulted in inhibitory effects …

Neurotoxic Effects Of Hiv-1 Gp120 And Interaction With Allopregnanolone, Kimberly A. Thornton

Honors Theses

With increasing incidence of HIV and its associated neurocognitive disorders, there has emerged a need for an antiviral with improved delivery to the CNS. In searching for drug candidates that meet these criteria, some have noted that certain steroid hormones like estrogen and progesterone that naturally accumulate in the CNS show neuroprotective effects in cells exposed to HIV proteins. This investigation focused on testing the potential protective effects of the progesterone metabolite, allopregnanolone (AlloP), against HIV protein gp120-mediated neurotoxicity. Experiments were conducted using SH-SY5Y neuroblastoma cells that were exposed to varying concentrations of AlloP (0-100 nM) in conjunction with one …

Safe Injection Facilities, Timothy Kwong

Honors Theses

According to the Center of Disease Control and Prevention (CDC), “In 2016, a total of 63,632 persons in the United States died from drug overdoses; the age-adjusted rate was 19.8 deaths per 100,000 persons.” There have been countless programs with the sole purpose of reducing the amount of drug related deaths. Some with positive outcomes and others with negative outcomes. Since there is no feasible method of eradicating the problem as a whole, the next logical thing to do would to be creating effect prevention programs.

Safe Injection Facilities (SIFs) have been around for over three decades. They are widespread …

Predator Diet Affects Perceived Oviposition Site Quality For Mosquitoes, Brandon Mcdaniel

Honors Theses

Ovipositing freshwater organisms rely primarily on cues to determine site quality (Silberbush and Blaustein 2008) and to select an ideal habitat for their offspring (Resetarits 2014). Characteristics of high quality oviposition sites that yield the greatest fitness for offspring include the absence of predators and high resource availability that allows for optimal growth and development (Kershenbaum et al. 2012). It has been shown that predator presence is a large deterrent of oviposition due to threats of offspring survival, however, there is a little information about the predatory cues mosquitoes experience before ovipositing (Angelon and Petranka 2002). One hypothesis is that …

The Protective Role Of Estrogen On Hiv-1 Mediated Neurotoxicity, Macklin Licamied

Honors Theses

The prevalence of HIV among men have been in a steady inclination over the last several decades, yet the accelerated infection rate among older women is considerably concerning. Not only does the HIV virus affect the immune system but it also affects the central nervous system. One of its viral proteins, Tat, acts as an excitotoxin and disrupts the cell’s membrane potential by increasing the concentration of Ca2+ inside the cell. This influx of calcium ions leads to apoptosis and secretion of the cell’s contents into the surrounding area. Macrophages, along with other innate immune components, gather and induce the …

Synthesis Of (2r,6r)-Hydroxy-Norketamine For Evaluation Of Antidepressant Effects, Savannah Fairley

Honors Theses

Major Depressive Disorder, colloquially known as depression, is a devastating mental illness that affects a large portion of today's population. Following a drug side-effect that caused depression, the monoamine theory of depression was created, stating that depressive symptoms were caused by a decrease in concentrations of vital monoamine neurotransmitters at the synaptic cleft. Pharmaceutical remedies to combat depression were first introduced in the 1950s and to this date, most available drugs follow the monoamine theory. These drugs have a large loading dose lag time, numerous negative side effects, and still many patients do not experience relief from symptoms. In 2000, …

Dysregulation Of Human Phase I Enzymes In Apap Overdose Subjects With Low Alt Levels, Aaron Woodall
