EKU Faculty and Staff Scholarship

Environmental health and public health are profoundly local. The Association of Environmental Health Academic Programs (AEHAP) firmly agrees and for this reason, it is important to have local environmental health experts who know the pulse of their communities. AEHAP believes in supporting the advanced scientific education of environmental health in these communities through people from these communities. Accordingly, AEHAP has sought to promote and support accredited environmental health programs among a diverse cross-section of the U.S. higher education landscape. AEHAP’s students are diverse in many ways, including socioeconomically, racially, ethnically, and culturally. The value of this approach enhances ...

Hiv Integrase Inhibitor Pharmacogenetics And Clinical Outcomes: An Exploratory Association Study, Derek E. Murrell 2018 East Tennessee State University

Hiv Integrase Inhibitor Pharmacogenetics And Clinical Outcomes: An Exploratory Association Study, Derek E. Murrell

Electronic Theses and Dissertations

As HIV is now primarily a chronic condition, treatment is given life-long with changes as necessitated by alterations in tolerability and efficacy. Thus, personalized medicine may be useful in the prevention of unnecessary drug exposure and avoidable side effects. Three of the four currently available HIV integrase strand transfer inhibitors (INSTIs), raltegravir, elvitegravir, and dolutegravir, are widely utilized antiretrovirals in the USA and exhibit variations in outcomes among subjects. To interrogate differences among subjects receiving these drugs, we investigated the association of several single nucleotide polymorphisms (SNPs) with drug exposure, clinical outcomes, and subject-reported adverse events. HIV+ adults (≥18 years ...


Macrophytes And Atrazine In Ponds Of Southwest Missouri, Christine Michelle Cornish 2018 Missouri State University

Macrophytes And Atrazine In Ponds Of Southwest Missouri, Christine Michelle Cornish

MSU Graduate Theses

Wetlands are often the ultimate destination of agrochemicals. The increased use of these pollutants has resulted in their increased transport, via runoff and spray drift, into wetlands. Atrazine, a commonly used herbicide, has been detected in surface water, groundwater, soil, and sediment, and has shown to have adverse impacts on aquatic biota, such as fish and amphibians. Few studies have reported on the relationships between atrazine and macrophytes. I measured atrazine concentrations in surface sediments in agricultural, conservation, and golf course ponds of southwest Missouri, and investigated how those concentrations might be related to macrophyte communities, and pond environmental characteristics ...


Manganese Toxicity In The Dopamine Synthesis Pathway In Drosophila Melanogaster, Brandon Adair, Tamra E. Jones, Stefanie Otto-Hitt 2018 Carroll College

Manganese Toxicity In The Dopamine Synthesis Pathway In Drosophila Melanogaster, Brandon Adair, Tamra E. Jones, Stefanie Otto-Hitt

Life and Environmental Sciences Course-based Research Projects

Manganese is prevalent in Montana, and Manganese toxicity symptomatically resembles Parkinsons disease. The goal of this project was to determine whether exposure to high levels of Manganese affects the Dopamine synthesis pathway. For our experiment, we chose to measure the expression of the ple gene in Drosophila melanogaster that were exposed to Manganese during development. The ple gene codes for Tyrosine Hydroxylase, an enzyme that functions in the first rate-limiting step of Dopamine synthesis. We hypothesized that an abundance of Manganese would result in decreased expression of ple in larvae and observable motor function deficits among adult flies. To carry ...


Effects Of Sulfur Dioxide On Abda Gene Expression And Larval Development In Drosophila Melanogaster, Emma Esposito, Keenan McNally, Stefanie Otto-Hitt 2018 Carroll College

Effects Of Sulfur Dioxide On Abda Gene Expression And Larval Development In Drosophila Melanogaster, Emma Esposito, Keenan Mcnally, Stefanie Otto-Hitt

Life and Environmental Sciences Course-based Research Projects

In this experiment, we tested the effects sulfur dioxide exposure had on abd-A gene expression and larval development in Drosophila melanogaster. Previous studies showed that sulfur dioxide exposure inhibits development of gonads in adult flies and increases development time. We hypothesized that expression of abd-A would decrease in developing Drosophila exposed to sulfur dioxide. The abd-A gene is in the Hox gene family, which functions in the development of body segmentation. The abd-A gene is specific to the abdominal region of the fly, and is also important to the development of gonads and fat bodies. To test our hypothesis, we ...

The Effect Of Metal Pollutants On Cell Growth And Ttherm0058490expressionint Etrahymenathermophila, Inderbir Bains, William French, Stefanie Otto-Hitt

Life and Environmental Sciences Course-based Research Projects

In this experiment, we sought to answer the following question: Do higher levels of metal exposure affect expression of the TTHERM 00584900 gene in Tetrahymena thermophila? The TTHERM 00584900 gene produces an ATP-binding cassette protein that is responsible for removing metals and metalloids from Tetrahymena thermophila. It is hypothesized that the expression of TTHERM 00584900 will increase with exposure to metals. In order to test this hypothesis, Tetrahymena thermophila were randomly assigned to either a control group, which was cultured in a normal growth medium, or a treatment group, whichin addition to the medium was exposed to water contaminated with ...

Effects Of The Everyday Toxin, Titanium Dioxide, On Drosophila Melanogaster Nervous System Development, Maria Carparelli, Kelsey Ripley, Stefanie Otto-Hitt

Life and Environmental Sciences Course-based Research Projects

Titanium dioxide (TiO2) is a widely used compound found in everything from food packaging to sunscreens. When ingested, TiO2 is readily transported across membranes and efficiently stored within cells. Previous studies showed that exposure to TiO2 results in underdeveloped nervous systems. For our study, we attempted to answer the following question: Will exposing Drosophila melanogaster larvae to TiO2 affect expression of the Neur gene and development of the central nervous system? The Neur gene is crucial during the celldetermination stage of development as its encoded protein helps specify neuroblast development and aids in nervous system and sensory organ development. It ...


Effect Of Potassium Bromate On Oxr1 Gene Expression And Cell Growth In Tetrahymena Thermophila, Scott Khale, Brendan McMahon, Stefanie Otto-Hitt 2018 Carroll College

Effect Of Potassium Bromate On Oxr1 Gene Expression And Cell Growth In Tetrahymena Thermophila, Scott Khale, Brendan Mcmahon, Stefanie Otto-Hitt

Life and Environmental Sciences Course-based Research Projects

The purpose of our experiment was to answer the question: Does oxidative damage, induced by potassium bromate (KBrO3), affect growth rate and expression of the OXR1 gene in Tetrahymena thermophila? Potassium Bromate was chosen as the environmental stressor because it is a strong oxidizing agent that is used as a leavening agent in baked goods. It was hypothesized that expression of OXR1 would increase in Tetrahymena cells that were exposed to potassium bromate and that their growth rate would decrease. The exact mechanism and function of the OXR1 gene is still unknown; however, the literature suggests that it is required ...


Effect Of Nitrate Pollution On Tetrahymena Thermophila, Reegan DeBruycker, Hannah Sylvester, Stefanie Otto-Hitt 2018 Carroll College

Effect Of Nitrate Pollution On Tetrahymena Thermophila, Reegan Debruycker, Hannah Sylvester, Stefanie Otto-Hitt

Life and Environmental Sciences Course-based Research Projects

The question under investigation in this project was: Does an elevated concentration of nitrates have a negative eect on cell growth and expression of the CDC16 gene in the organism Tetrahymena thermophila? Exposure of Tetrahymena cultures to nitrates mimics the exposure of these organisms to nitrate pollution in the environment, which can occur due to septic tank leakage, nitrogen-rich fertilizer run o, and agricultural processes. The EPA standard for nitrate concentrations in drinking water is a maximum of 10ppm. In our experiment, Tetrahymena cultures were treated with media that contained 30ppm of nitrates for one week. The 30ppm nitrate concentration ...


The Effect Of Imidacloprid On Honey Bee Queen Fecundity, Jamilyn Martin, Julia D. Fine, Amy Cash-Ahmed, Gene E. Robinson 2018 Kaskaskia College

The Effect Of Imidacloprid On Honey Bee Queen Fecundity, Jamilyn Martin, Julia D. Fine, Amy Cash-Ahmed, Gene E. Robinson

PRECS 2018

Imidacloprid is a neonicotinoid insecticide commonly used in agricultural settings to control insect pests by acting as an agonist of acetylcholine receptors and inducing paralysis and mortality. In small doses, imidacloprid can cause loss of memory and foraging ability along with impaired learning and a lowered immune response in western honey bees (Apis mellifera). Effects of neonicotinoid insecticides on colony reproduction have been documented including decreased colony expansion, queen failure and replacement, and decreased queen egg laying.

For this study, we examined the effects of imidacloprid on the fecundity of queen bees when their worker attendants were exposed to low ...

Preparation And Characterization Of Functionalized Heparin-Loaded Poly-Ɛ-Caprolactone Fibrous Mats To Prevent Infection With Human Papillomaviruses, Daniela Gonzalez, Jorge Ragusa, Peter C. Angeletti, Gustavo F. Larsen

Chemical and Biomolecular Engineering -- All Faculty Papers

In this study, heparin-loaded poly-ε-caprolactone (PCL) fibrous mats were prepared and characterized based on their physical, cytotoxic, thermal, and biological properties. The main objective of the work described here was to test the hypothesis that incorporation of heparin into a PCL carrier could serve as bio-compatible material capable of inhibiting Human Papillomavirus (HPV) infection. The idea of firmly anchoring heparin to capture soluble virus, vs. a slow heparin release to inhibit a virus in solution was tested. Thus, one material was produced via conventional heparin matrix encapsulation and electrohydrodynamic fiber processing in one step. A second type of material was ...

Variation In Airborne Pollen Concentrations Among Five Monitoring Locations In A Desert Urban Environment, Tanviben Y. Patel, Mark P. Buttner, David Rivas, Chad L. Cross, Dennis A. Bazylinski, Joram S. Seggev

Environmental & Occupational Health Faculty Publications

The urbanization of the Las Vegas Valley has transformed this part of the Mohave Desert into a green oasis by introducing many non-native plant species, some of which are allergenic. Typically, one monitoring station is established per city to obtain pollen counts for an entire metropolitan area. However, variations in pollen concentrations could occur among different microenvironments. The objective of this study is to measure and compare pollen concentrations in five locations in Las Vegas to determine if there are significant differences between microenvironments within the city. Air samples were collected from five sites across the Las Vegas Valley over ...


Anti-Tumor Activity Of Phenoxybenzamine And Its Inhibition Of Histone Deacetylases, Mario A. Inchiosa 2018 New York Medical College

Anti-Tumor Activity Of Phenoxybenzamine And Its Inhibition Of Histone Deacetylases, Mario A. Inchiosa

NYMC Faculty Publications

The principal finding from this study was the recognition that the α-adrenergic antagonist, phenoxybenzamine, possesses histone deacetylase inhibitory activity. Phenoxybenzamine is approved by the United States Food and Drug Administration for the treatment of hypertensive crises associated with tumors of the adrenal medulla, pheochromocytomas. It has several "off label" indications relative to its capacity to relax vascular smooth muscle and smooth muscle of the urogenital tract. The drug also has a long history of apparent efficacy in ameliorating, and perhaps reversing, the severe symptoms of neuropathic pain syndromes. Our interest in this feature of the drug relates to the fact ...


Zolpidem Facilitated Sexual Assaults: A Hair Method Validation, Danielle N. Chasworth 2018 CUNY John Jay College

Zolpidem Facilitated Sexual Assaults: A Hair Method Validation, Danielle N. Chasworth

Student Theses

A liquid chromatography tandem mass spectrometry (LC-MSMS) method was developed and validated to detect for the presence of zolpidem in human hair samples. Zolpidem is a sedative hypnotic whose adverse effects make it a common drug found in drug facilitated crimes (DFC). It is important to be able to detect and quantitate the drug after a long period of time due to the victim’s delayed reporting of the crime. Hair’s long window of detection makes it a useful matrix for DFC investigations. The linear range of the assay was targeted at 2 pg/mg to 1,000 pg ...


Defining The Radioresponse Of Mossy Cells, Devon Ivy 2018 California State University, San Bernardino

Defining The Radioresponse Of Mossy Cells, Devon Ivy

Electronic Theses, Projects, and Dissertations

Clinical radiotherapy is used to treat a variety of brain tumors within the central nervous system. While effective, it can result in progressive and debilitating cognitive impairment that can diminish quality of life. These impairments have been linked to hippocampal dysfunction and corresponding deficits in spatial learning and memory. Mossy cells are a major population of excitatory neurons located within the dentate hilus and highly involved in hippocampal circuitry. They play critical roles in spatial navigation, neurogenesis, memory, and are particularly vulnerable to a variety of neurotoxic insults. However, their sensitivity to ionizing radiation has yet to be investigated in ...
