Probing The Functional Relevance Of Reactive Hippocampal Neurogenesis In A Model Of An Alcohol Use Disorder, Chelsea Rhea Geil Nickell

Theses and Dissertations--Pharmacy

Alcoholism, or alcohol use disorders (AUDs), represent a major public health concern both locally and globally. Critically, excessive alcohol consumption results in neurodegeneration in brain regions such as the hippocampus which is known for its role in learning and memory. Recovery of hippocampal volume loss has been observed after prolonged abstinence, but the mechanisms underlying this process are not well understood. Adult neurogenesis is thought to contribute to this recovery since after alcohol exposure a reactive increase in adult neurogenesis is observed. This reactive neurogenesis (the process by which brain insult results in a compensatory increase in neurogenesis) may represent …

Chronic Pancreatitis, Pain, And Anxiety In An Alcohol And High Fat Mouse Model, Tiffanie Clinkinbeard

Theses and Dissertations--Gerontology

Homeodynamic space (HDS) shrinks as vulnerability increases with aging and repeated damage to the cells. HDS is lost in alcoholic pancreatitis patients due to overconsumption of alcohol, smoking, and high fat diets. Etiologically relevant animal models for study of chronic pancreatitis (CP) are needed. In order to begin filling this gap a central purpose of this dissertation research was to examine relationships between the alcohol and high fat diet (AHF) and pancreatitis with attention to hypersensitivity and anxiety-like behaviors. The AHF diet induced pancreatitis described here etiologically mimics human risk factors of AHF consumption for advancement to alcoholic CP.

Reducing Depression Among Older Adults: Informal Helping Versus Volunteering, Salih Salihoglu

MPA/MPP/MPFM Capstone Projects

Volunteerism is an unpaid productive activity that is exercised within a formal organization to benefit others that are not part of family or friends (Musick & Wilson, 2008). Alternatively, individuals could engage in informal helping which would be an activity undertaken outside a formal, structured organization. This paper addresses whether informal helping is also effective in reducing depression for older adults alongside volunteering. I hypothesize that informal helping is effective in reducing depression only when exercised for short durations. On the other hand, I hypothesize that volunteerism is only effective when exercised for long periods of time. I try to …

Exploration Of The Misuse, Abuse, And Diversion Of Gabapentin, Rachel Vickers Smith

Theses and Dissertations--Epidemiology and Biostatistics

Gabapentin is currently approved by the Food and Drug Administration (FDA) as an adjunctive anti-convulsant and an analgesic for post-herpetic neuralgia. Though gabapentin was initially presumed to have limited or no abuse potential, which may have contributed to its widespread off-label prescribing, there have been increasing anecdotal and published reports of its misuse by substance abusers in the community and penal system. However, to date, there has been limited systematic evaluation of the scope and risk of gabapentin misuse and its associated effects. This dissertation assesses the etiology and prevalence of gabapentin misuse, abuse, and diversion in a multi-faceted approach, …

Determinants Of An Individual's Suicide Intention In South Korea, Nam Keun Choi

MPA/MPP/MPFM Capstone Projects

This study has examined a variety of variables that influence an individual’ s suicide intention, and analyzed the impact of these variables. The data are from the 2014 wave of the Korea Welfare Panel Survey (KoWePS). I analyze data on 13,687 out of 17,134 survey participants.

The dependent variable of my study is suicide intention such as suicidal thoughts and behaviors. The independent variables are classified into three categories: socio-demographic, psychological and mental health. Socio-demographic variables are gender, age, education, marital status, and income. Psychological variables are self-esteem, satisfaction with life, and religion. Mental health variables are depression, alcohol use, …

Loss Aversion In Cocaine Users: Influence Of Risk And Commodity Type, Justin Charles Strickland

Theses and Dissertations--Psychology

Numerous studies in behavioral economics have demonstrated that individuals are more sensitive to the prospect of a loss than a gain (i.e., loss aversion). Although loss aversion has been well described in healthy populations, little research exists in individuals with substance use disorders. The purpose of this study was to comprehensively evaluate loss aversion in cocaine users. Participants completed measures designed to assess loss aversion for drug and non-drug commodities under varying risk conditions. Cocaine demand was determined using a cocaine purchase task. Cocaine users showed a loss aversion score that was consistent across commodity and risk conditions. Compared to …
