Insulin-Like Growth Factor-1 Overexpression Mediates Hippocampal Remodeling And Plasticity Following Tbi, Erica Latrice Littlejohn

Theses and Dissertations--Physiology

Every year over 2.5 million traumatic brain injuries (TBI) occur and are the leading cause of death and disability among adolescents. There are no approved treatments for TBI. Survivors suffer from persistent cognitive impairment due to posttraumatic tissue damage and disruption of neural networks which significantly detract from their quality of life. Posttraumatic cognitive impairment depends in part on the brain's limited ability to repair or replace damaged cells. Immature neurons in the hippocampus dentate gyrus, a brain region required for learning and memory, are particularly vulnerable to TBI. Insulin-like growth factor-1 (IGF1) is a potential therapeutic for TBI because …

Rhodococcus Equi In The Foal – Improving Diagnostic And Prevention Measures, Fernanda Bicudo Cesar

Theses and Dissertations--Veterinary Science

Although Rhodococcus equi (R. equi), previously known as Corynebacterium equi, was first isolated from pneumonic foals almost a century ago, it remains the most common cause of subacute or chronic granulomatous bronchopneumonia in foals. While the majority of foals exposed to R. equi develop a protective immune response (regressors), others exhibit a unique susceptibility to infection (progressors). The determinants for either outcome are not completely understood. Therefore, current diagnostic and preventive measures are suboptimal and require betterment. In light of this current need, we hypothesized that immunoglobulin G subisotype T [IgG(T)] against the virulence-associated protein A (VapA) …

Cellular And Molecular Basis Of Equine Arteritis Virus Persistent Infection In The Stallion Reproductive Tract: Characterization Of Local Host-Pathogen Interactions Mediating Long-Term Viral Persistence, Mariano Carossino

Theses and Dissertations--Veterinary Science

Equine arteritis virus (EAV) has a global impact on the equine industry being the causative agent of equine viral arteritis (EVA), a reproductive, respiratory, and systemic disease of equids. A distinctive feature of EAV infection is that it establishes long-term persistent infection in the reproductive tract of stallions and is continuously shed in the semen (carrier state). Recent studies showed that long-term persistence is associated with a specific allele of the CXCL16 gene (CXCL16S). However, the cellular and molecular mechanisms underlying the establishment and maintenance of persistent infection are yet to be determined. The studies were undertaken herein …

Utilization Of Web‐Based App To Target Obesogenic Factors In Rural Kentucky Counties With High Rates Of Obesity, Erin M. Casey

Theses and Dissertations--Nutrition and Food Systems

Due to socioeconomic disparities and geographic isolation, rural Kentucky residents bear a greater burden of poor health compared to national averages. Specifically, rural Kentucky residents are at greater risk of becoming obese and suffering from comorbidities of obesity such as type 2 diabetes, hypertension and cardiovascular disease. The purpose of the present study was two-fold. First, we the barriers to nutrition and physical activity unique to rural Kentucky counties which high proportions of obese adults (< 40%) were examined and extrapolated. Second, this information was used to develop a health and wellness app tailored to rural Kentucky counties. The objective was met via a formative assessment regarding causes for obesity in three rural Kentucky counties using focus groups. From these discussions, two major themes arose: barriers to good nutrition and physical activity, and desired web‐app features. From this assessment, FitFaceoff was developed and released into the same counties. Usage and user interaction were assessed using GoogleAnalytics™ software. Analysis revealed poor user liking and unsuccessful implementation of FitFaceoff, however further qualitative research is needed to evaluate poor user reception of FitFaceoff and possible future directions.

Mechanisms And Potential Therapy On Disrupted Blood Pressure Circadian Rhythm In Diabetes, Tianfei Hou

Theses and Dissertations--Pharmacology and Nutritional Sciences

Arterial blood pressure (BP) undergoes a 24-hour oscillation that peaks in the active day and reaches a nadir at night during sleep in humans. Reduced nocturnal BP fall (also known as non-dipper) is the most common disruption of BP circadian rhythm and is associated with increased risk of untoward cardiovascular events and target organ injury. Up to 75% of diabetic patients are non-dippers. However, the mechanisms underlying diabetes associated non-dipping BP are largely unknown. To address this important question, we generated a novel diabetic db/db-mPer2^Luc mouse model (db/db-mPer2^Luc) that allows quantitatively measuring of mPER2 protein oscillation …

Efforts To Reduce Concomitant Opioid And Benzodiazepine Prescribing At The Lexington Veterans Affairs Medical Center, Kaitlyn A. Staton

MPA/MPP/MPFM Capstone Projects

The United States is in the throes of an opioid epidemic. Any person who uses an opioid medication may experience an intentional or unintentional overdose. An overdose is more likely to occur when an individual ingests an opioid in combination with certain classes of medications, such as benzodiazepines or nonbenzodiazepines (Z-drugs). These medications are more likely to cause sedation and respiratory depression when taken together. Veterans, due to their unique mental and physical health challenges, are more likely to experience an overdose when they receive a combination of opioid therapy with benzodiazepine or Z-drug therapy as opposed to a single …

The Effect Of Early Life Photoperiod Manipulation On Cocaine-Induced Behavioral Sensitization In Male And Female Japanese Quail, Shannon Elizabeth Eaton

Theses and Dissertations--Psychology

Estrogens seem to play a role in the locomotor activating effects of cocaine. Japanese quail provide a good model for hormonal manipulation as alterations of their photoperiod controls hormone levels. The current study aims to examine the role of early life photoperiod manipulation in cocaine-induced behavioral sensitization in quail. It was expected that if quail were raised on a short photoperiod, they would have a reduction in gonadal hormones and this reduction in hormones would affect the acquisition of cocaine-induced behavioral sensitization. Quail were raised on an 8L:16D or a 16L:8D light cycle. Following 2 days of habituation, quail were …

Cocaine Choice: A Novel Procedure For Investigating Neuronal Activation Mediating Cocaine Preference, Jonathan Jenn-Sheng Chow

Theses and Dissertations--Psychology

Cocaine use disorder is a significant health problem, negatively impacting individuals afflicted. While preclinical self-administration research has provided invaluable insight into the neurobehavioral mechanisms that underlie cocaine abuse, cocaine use outside of the laboratory occurs within an environment where other goods are also available ubiquitously. Although there is an ever-increasing literature investigating drug vs. non-drug choice in rodent models and how alternative goods can compete with the subjective value of cocaine, the neurobiological mechanisms that are associated with cocaine preference remains largely unknown. Additionally, current drug vs. non-drug choice studies use procedures that confound preference with intake, such that preference …
