Theses and Dissertations
Cerebral malaria (CM), a severe manifestation of Plasmodium infection, prompts our investigation into the nuanced role of pipecolic acid in its pathophysiology. To unravel the molecular intricacies, we conducted in vitro lysine labeling techniques of mice infected with P. berghei ANKA parasites, and human P. falciparum grown in vitro, aiming to discern the impact of Plasmodium on pipecolic acid production. Previous observations indicated an elevation in pipecolic acid levels correlating with neurological decline in children with CM. In our study, confirming elevated pipecolic acid presence in the plasma and brain tissues of CM patients and the animal model of CM, …

Haloperidol Paradoxical Behavior Induced Cell Proliferation Through Pkb/Akt And Abolished By Mir-Let-7c, Mounira Morgem
Dissertations (2016-Present)
Haloperidol is a typical antipsychotic drug; it is widely used for people with various psychiatric conditions such as schizophrenia, bipolar disorder, major depressive disorder, and dementia. Despite its effectiveness in controlling delusions, hallucinations, agitation, and other disruptive behavioral symptoms in these psychiatric conditions, it has adverse side effects such as extrapyramidal manifestation and endocrinologic and metabolic changes. Initial evidence shows that haloperidol has antitumor properties in several cancer types by inhibiting cell proliferation and inducing apoptosis. However, other reports indicate that haloperidol promotes cell proliferation in other cells, raising concerns about its association with an increased risk of cancer which …

The Role Of Extracellular Vesicles And Their Cargo In Intercellular Communication, Chongyu Zhang
Dissertations
Extracellular vesicles (EVs) are membranous vesicles secreted by most cells. They contain lipids, proteins, and nucleic acids, including microRNAs (miRNA), and function in intercellular communication by endocytosis into other cells. EVs in diseased states carry miRNAs and proteins reflective of the changed state of cells and can be endocytosed into other cells to exert regulatory effects. Thus, EVs represent a form of paracrine genetic regulation in health and disease. Myocardial infarction (MI) and pulmonary embolism (PE) are leading causes of cardiovascular deaths worldwide. It is important to develop new diagnostic and therapeutic approaches that could lead to medical advances. Circulating …

ONU Student Research Colloquium
The overall objective of the study was to assess the acute behavioral effects of currently used antidepressants and anxiolytics in male and female mice lacking regulator of G protein-signaling (RGS) proteins 2 and 4 and their wild-type counterparts. RGS 2 and 4 proteins negatively modulate signaling pathways of G protein-coupled receptors (GPCRs), which play an important role in mediating the effects of monoamine neurotransmitters such as dopamine, norepinephrine, and serotonin. These neurotransmitters in turn play an important role in the action of antidepressant and anxiolytic medications. The study was undertaken because no studies till date have systematically assessed the behavioral …

Effects Of Kappa Opioid Receptor Manipulation On Methamphetamine-Induced Behavioral Sensitization In Adolescent Male And Female Rats, Hiroyoshi Matsui Mr, Sarah Seeley, Manoranjan S. D'Souza
ONU Student Research Colloquium
Methamphetamine abuse amongst adolescents has been on the rise in the United States. In this study, we assessed the effects of manipulation of KORs on methamphetamine-induced behavioral sensitization in adolescent male and female rats. Methamphetamine-induced behavioral sensitization is an animal model to study methamphetamine addiction. Behavioral sensitization usually occurs in animals who have been treated with methamphetamine followed by a period of withdrawal. It is hypothesized that brain circuits are altered during the period of withdrawal after methamphetamine exposure resulting in sensitized (increased) responses to methamphetamine at the end of the withdrawal period. The experiment was conducted over 28 days. …

In Silico Identification Of Small Molecule Agonist Binding Sites On Kcc2, Kenyon Mitchell, Alfred Amendolara, Ruth Hunter, Jaden Miner, Andrew Payne
Annual Research Symposium
Purpose: Potassium-Chloride Cotransporter 2 (KCC2) is a neuronal membrane protein specific to the central nervous system. It is responsible for removing Cl- ions from the intracellular space, maintaining a normal Cl- gradient essential for proper function at inhibitory synapses. Dysregulation causes an upward shift in the Cl- reversal potential resulting in a hyperexcitable state of the postsynaptic neuron. Existing literature indicates that KCC2 may be involved in the addiction pathway of a variety of drugs of abuse, including opioids and alcohol. This makes KCC2 an attractive potential drug target when treating substance use disorders. A novel direct KCC2 agonist, VU0500469, …

Beta adrenergic receptor antagonists, known as beta blockers, are one of the most prescribed medications in both pediatric and adult cardiology. Unfortunately, most of these agents utilized in the pediatric clinical setting are prescribed off-label. Despite regulatory efforts aimed at increasing pediatric drug labeling, a majority of pediatric cardiovascular drug agents continue to lack pediatric-specific data to inform precision dosing for children, adolescents, and young adults. Adding to this complexity is the contribution of development (ontogeny) and genetic variation towards the variability in drug disposition and response. In the absence of current prospective trials, the purpose of this comprehensive review …

The use of electronic nicotine delivery systems (ENDS) has become popular in recent years as an alternative to traditional cigarettes. These devices heat and subsequently vaporize e-liquids for inhalation by the user, which allows for the delivery of ingredients such as flavorings, nicotine, and solvents through the vapor. Flavorings used in e-liquids are “generally recognized as safe” (GRAS) for consumption by the Food and Drug Administration (FDA), however there are currently no recommendations on safety regarding the inhalation of flavoring agents. While research characterizing effects of e-liquids and their flavorings is abundant in lung and respiratory tract models, few studies …
