Effects Of Catharanthine On Dopamine Release In The Nucleus Accumbens And Ethanol Consumption, Emily Baldwin
Effects Of Catharanthine On Dopamine Release In The Nucleus Accumbens And Ethanol Consumption, Emily Baldwin
Undergraduate Honors Theses
This thesis discusses the history of catharanthine and related compounds, and their potential anti-addictive properties. Current research is exploring possible mechanisms of these properties. Past studies have found catharanthine has effects on neurons that project to the mesocorticolimbic system, an area implicated in addiction. We have seen that catharanthine decreases evoked dopamine (DA) release but increases basal DA release. This is the first study to investigate catharanthine’s effect on DA transmission in vivo. Using microdialysis, we determined the effect of catharanthine on DA in the nucleus accumbens of the striatum. This study determines the effect of different doses of …

The Effects Of Alcohol On The Developing Drosophila Nervous System, Erica E. Hassoun
The Effects Of Alcohol On The Developing Drosophila Nervous System, Erica E. Hassoun
The Cardinal Edge
Ethanol is the most common human teratogen, contributing to fetal alcohol syndrome (FAS) when effects are the most severe. Key effects of fetal alcohol syndrome are observed in the nervous system. The high prevalence of prenatal alcohol exposure necessitates novel treatment and prevention methods. However, ethical issues prevent researching humans in utero. For this reason, the fruit fly Drosophila melanogaster has emerged as a model organism for studying FAS. Because Drosophila is a small and non-placental organism, its environment can be easily controlled, allowing for specific doses and time periods of ethanol exposure to be studied. This review discusses findings …

Adolescents exposed to violence are at elevated risk of developing most forms of psychopathology, including depression, anxiety, and alcohol abuse. Prior research has identified emotional reactivity and difficulties with emotion regulation as core mechanisms linking violence exposure with psychopathology. Scant research has examined behavioral responses to distress as a mechanism in this association. This study examined the association of violence exposure with distress tolerance—the ability to persist in the face of distress—and whether lower distress tolerance linked violence exposure with subsequent increases in depression, anxiety, and alcohol abuse problems during adolescence. Data were collected prospectively in a sample of 287 …
Alcohol As A Catalyst For Hiv-Associated Neuroinflammation And Tbi-Induced Iron Toxicity, Agnieszka Agas
Alcohol As A Catalyst For Hiv-Associated Neuroinflammation And Tbi-Induced Iron Toxicity, Agnieszka Agas
Dissertations
Alcohol has long been considered an exacerbator of diseases, disorders, and injuries as well as many of the accompanying symptoms. As an alternative approach, this dissertation explores alcohol as a catalyst for two different human disease conditions, human immunodeficiency virus (HIV)-associated neuroinflammation and traumatic brain injury (TBI)-induced iron toxicity. In HIV-1 infection, this dissertation presents a novel anti-viral drug, called Drug-S, for a possible inhibition and treatment of HIV-1 disease progression.
The first aim explores the influence of alcohol with HIV-associated neuroinflammation on macrophage migration across an in vitro model of the blood brain barrier. There is a gap in …
Eeg Features Of Explore-Exploit Decision-Making In Alcohol Use Disorder, Ethan Campbell
Eeg Features Of Explore-Exploit Decision-Making In Alcohol Use Disorder, Ethan Campbell
Psychology ETDs
Little research has assessed explore-exploit behavior in addiction using drug cues and even fewer studies have measured the neural activity underlying these behaviors. The present study aims to explore brain mechanisms of disordered decision-making in alcohol use disorder (AUD) through electroencephalography (EEG) during performance of a novelty bandit task with alcohol imagery and using a validated computational model of explore-exploit dynamics. Individuals with AUD (n = 28) and age and sex-matched controls (n = 27) showed differences in choice behavior and showed differences in EEG activity as a function of exploratory behavior, chosen stimulus type, and explore-exploit computational …

Faculty Scholarship
Purpose: People living with HIV infection (PLWH) experience increasing risk for non-AIDS diseases including liver dysfunction and injury. Both HIV-infection and heavy alcohol drinking (HAD) are known to cause gut microbial dysbiosis and systemic inflammation that may potentially contribute to altered Gut-Liver axis. However, the specific pathogenic features associated with combinatorial harmful effects of alcohol and HIV infection on gut-liver interactions are not completely understood. This study evaluate the pathogenic changes in the Gut-Liver axis in PLWH with HAD.
Examining The Role Of The Drosophila Melanogaster Unc13 Protein In Open Field Activity Using Rnai, Islam Orabi
Examining The Role Of The Drosophila Melanogaster Unc13 Protein In Open Field Activity Using Rnai, Islam Orabi
Honors Theses
Unc13 are proteins in the presynaptic neurons essential in controlling synaptic vesicle fusion and synaptic transmission. Recently, the reduction of Drosophila melanogaster Unc13 proteins (Dunc13), were found to result in a resistance to alcohol, highly reminiscent of tolerance formation. I investigated whether genetically reducing Dunc13 activity in Drosophila brain regions leads to different forms of behavioral plasticity using an open field activity paradigm. In my approach, a Dunc13 RNAi transgene was expressed in the Drosophila brain within the mushroom body, the ellipsoid body, and in all neurons. The activities of the flies were examined in the open field paradigm to …

What’S The Hang-Up On Hangovers?, Anthony Isenhour
Osmosis Magazine
Getting a hangover after drinking the night before can lead to varying regrets the next morning depending on a variety of factors including gender, weight, food consumption, and alcohol consumption. What a hangover feels like can vary a lot too: headaches, nausea, fatigue, etc.
Scientists are interested in understanding hangovers and how to prevent them because they experience them too.

Predicting Young Adults’ Intentions And Involvement In Alcohol-Influenced Aquatic Activity, Hannah L M Calverley, Lauren A. Petrass Ph.D., Jennifer D. Blitvich
International Journal of Aquatic Research and Education
Globally, alcohol consumption is a public health issue and a risk factor for drownings among young adults. While studies have identified a prominence of alcohol in youth drownings, little is known about the factors that influence young adults’ involvement in alcohol-influenced aquatic activity. The current study aimed to identify the predictors of young adults’ intention to participate, and past participation, in alcohol-influenced aquatic activity. A reliable and valid survey, informed by the Theory of Planned Behavior, was distributed to young adults (aged 18-24 years) educated in the UK and Australia. Cumulative odds ordinal logistic regressions with proportional odds were …
Characterization Of Alcohol-Mediated Promotion Of Breast Cancer Stem Cells, Mckenna Below
Characterization Of Alcohol-Mediated Promotion Of Breast Cancer Stem Cells, Mckenna Below
Master's Theses
Breast cancer is the leading cause of cancer-related death in women globally, and one in eight women will be diagnosed with breast cancer at some point in her life. Alcohol consumption has been linked to increase breast cancer risk and increased risk of tumor recurrence. Understanding the molecular mechanisms of modifiable lifestyle factors such as alcohol consumption will help to lower these risks and design more effective therapeutic approaches. Estrogen Receptor positive (ER+) breast cancer comprises approximately 70% of all breast cancers, and these tumors are effectively targeted by endocrine therapy in the form of estrogen deprivation with aromatase inhibitors, …

Substance use disorders (SUD) account for a large number of mental health diagnosis in the United States and around the world. Approximately 13.6 million adults 26 or older and 5.1 million young adults (ages 18-24) battled with a SUD in 2017. Alcohol Use Disorder (AUD) alone effects nearly 6% of the adult population within the United States. This creates a substantial burden on the individual, with alcohol being the third-leading cause of preventable death in the United States. Few treatments for AUD exist, with no new FDA-approved therapeutic treatments within the last 15 years. Additionally, the limited treatments we do …

Identifying Genes Downstream Of Mef2 That Influence Ethanol Sedation In Drosophila Melanogaster, Ananya Talikoti
Theses and Dissertations
Alcohol use disorder is a global public health issue that affects millions across the world. It can result in negative physical and mental health outcomes, and currently treatment options are limited and rates of relapse are high. Identifying genes that affect aspects of ethanol behaviors in model organisms, such as Drosophila melanogaster, can serve to eventually develop more robust therapeutic interventions for those experiencing alcohol dependence. Previous studies have identified a relationship between a person's initial sensitivity to alcohol and their abuse potential for the drug in later life. Therefore, we can study sedation behaviors in Drosophila melanogaster to …

Pharmacokinetics And Reward-Related Behaviors Of Ethanol In Male And Female Japanese Quail (Coturnix Japonica), Shannon Eaton
Theses and Dissertations--Psychology
Ethanol is one of the most widely used and abused drugs. Problem use is associated with many different health problems and the economic burden is in the billions of dollars. Additionally, many people have difficulty controlling their ethanol consumption and about 5% of adults end up with an alcohol use disorder (AUD). Many people with an AUD often find themselves in a cycle of binge, remission, and relapse.
Following ethanol consumption ethanol enters the bloodstream from the small intestine where it gets distributed to peripheral tissues. Ethanol in the bloodstream is cleared from the system by the liver. The primary …
