The purpose of the study was to create an instrument to assess the individual preferences of older adults for these products in a community living environment. Research questions included: (1) …

Puberty-Associated Changes In Kiss1r, Mc3r, And Mc4r In The Ewe, Ashleigh Caitlyn Thomson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The neural mechanisms that control the onset of puberty are not completely understood. In livestock, the onset of puberty relies on an increase in gonadotropin releasing hormone (GnRH) and luteinizing hormone (LH). Kisspeptin, neurokinin B, and dynorphin neurons (KNDy) and their receptors, Kiss1r, NK3R, and KOR, respectively, are important regulators of puberty. Previous data from our laboratory has shown that KNDy neurons may be responding to other inputs, including the melanocortin system, that will affect the timing of puberty. Given this, we examined kisspeptin receptor (Kiss1r) mRNA expression in GnRH neurons as well as examining melanocortin 3 and 4 receptor …

Examining Invalid Brief Child Abuse Potential Inventory Profiles Within A Randomized Controlled Trial For Toddler-Aged Children And Their Parents, Lindsay Rebecca Druskin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Child abuse is a significant public health concern that impacts children worldwide. Efforts to connect at-risk parents with prevention and intervention programs require the use of high-quality measures that evaluate child abuse potential. Researchers frequently use the Child Abuse Potential Inventory (Milner, 1986) and the Brief Child Abuse Potential Inventory (BCAP; Ondersma et al., 2005) which contain Validity indices that evaluate response patterns such as social desirability responding. The measure developers recommended that abuse risk scores from invalid profiles be disregarded in clinical and research settings; however, little is known about factors that may relate to invalid responses and whether …

S(+)-Propylnorapomorphine Hydrochloride Alters Mutant Huntingtin Aggregation And Membrane Interactions, Gabriella M. Pettipas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Huntington’s disease (HD) is an autosomal dominant neurodegenerative disorder resulting from an abnormally long CAG repeat in the huntingtin gene. This results in an expanded polyglutamine (polyQ) domain in the huntingtin protein (htt) that directly leads to self-assembly of huntingtin (htt) into a variety of aggregate species that underlie cellular toxicity. Interaction of protein aggregates with a variety of lipid membranes has been linked to disease pathology. Here, the ability of a small molecule S(+)-propylnorapomorphine (NM) hydrochloride to modulate htt-exon1(46Q) aggregation and interactions with lipid membranes was determined. ThT assays were performed to quantify fibril formation of htt in the …

Kinetic Study Of Oh Radical Reactions With Cyclopentenone Derivatives, Patrick Kipkoech Rutto

Graduate Theses, Dissertations, and Problem Reports (ETD)

Conjugated a, b-unsaturated carbonyl compounds like cyclopentenone play a significant role in various environmental processes. These compounds are formed in combustion and Earth’s atmosphere from the oxidation of cyclic ketones such as cyclopentanone. Once formed under oxidative conditions, cyclopentenone may react with presence of free radicals like OH in the atmosphere molecules to form vinoxy type resonantly stabilized radicals. The presence of free radicals species like OH, O2 in the atmosphere can react with these molecules resulting into intermediate products that dissociate to give final products. Experimental and theoretical investigations in the reactions of cyclopentenone derivatives with these small free …

Estimating Home Range Size And Density Of White-Tailed Deer (Odocoileus Virginianus) In West Virginia, Sarah M. Pesi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Big game hunting is an important source of revenue and recreation in the United States. Of big game species, white-tailed deer (Odocileus virginianus) are the most heavily pursued. White-tailed deer are a widespread generalist species, capable of existing at high densities. Hunting is often used as the primary method of managing deer populations, particularly in the eastern United States, where there is a lack of large predators. When populations reach high densities, there can be negative effects on the environment and conflicts with humans. Managers must consider both creating adequate hunting opportunities and reducing negative impacts when managing …

Investigating The Effect Of Using Humorous Threats In Recreation Area Rules Signage To Influence Behavioral Intentions, Jacob Timothy Vargas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Communicating the importance of rules and warnings to visitors of recreational parks through signage can be difficult. However, it is one of the most important things to keep visitors safe. Oftentimes, these signs use fear of punishment or injury to discourage certain behaviors. According to studies following the Extended Parallel Processing Model (EPPM), using threats can backfire and cause visitors to use maladaptive fear responses to counteract a threat message if the content is too extreme or too psychologically close. Humor is a versatile tool that can be used to grab attention, temper perceptions, and influence decision-making. Comedians like Jon …

Electronic Symptom Management Using Pros In A Rural, Appalachian Medical Oncologic Population, Andrea Ray Bailey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: Systemic chemotherapy is a cornerstone of cancer treatment, but it often leads to significant side effects, which may impact patients' quality of life and lead to increased acute healthcare utilization. Although patients are typically informed of potential symptoms and advised to seek care as needed, many struggle to understand and manage symptoms effectively. Patient-reported outcomes (PROs) have been shown to improve symptom monitoring, decrease symptom burden, and reduce emergency department visits and hospital admissions. Electronic patient-reported outcomes (ePROs), in particular, offer timely and accessible symptom tracking, though their effectiveness has largely been evaluated within urban clinical trial settings and …

INTRODUCTION: The Appalachian region, spanning 13 states from New York to northern Mississippi, experiences the suicide rates in the United States (U.S.), underscoring a public health crisis exacerbated by persistent socioeconomic challenges. West Virginia (WV), the only state entirely within Appalachia, serves as a focal point for understanding the broader suicide crisis in the region, as WV has the highest suicide rates in the region. Moreover, the state has several unique socioeconomic factors, like increased poverty, lower educational attainment, limited access to healthcare, and a high prevalence of chronic pain and substance that may contribute to elevated rates of suicide. …

Evaluating The Efficacy Of The Archaeal Proteasome To Alleviate Protein-Misfolding Retinopathy, Celine Brooks

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nearly all neurodegenerative diseases (NDs) and some eye diseases are characterized by the presence of misfolded and aggregated proteins. The ubiquitin proteasome system (UPS) is responsible for degrading the majority of proteins including misfolded and aggregated proteins. However, in NDs the performance of the UPS is impaired, and this impairment partially comes from these protein aggregates inhibiting the proteasome. This inhibition leads to an accumulation of protein aggregates, more proteasomal inhibition, and fewer chaperones for newly synthesized proteins, triggering a collapse in proteostasis, which is thought to contribute to the pathogenesis of NDs. Consequently, stimulating proteasome function is being investigated …

Policy Dynamics In Young Democracies: Attention, Electoral Change, And Responsiveness In Ghana And South Africa, Christiana Bugri

Graduate Theses, Dissertations, and Problem Reports (ETD)

My dissertation is a collection of three essays that assess the nature of government attention in young democracies. Theories of the policy process focus on policy dynamics in Western democracies with little application to non-Western democracies. This dissertation bridges this gap by studying policy dynamics in the neopatrimonial democracies of Ghana and South Africa. The dissertation sheds light on how the unique features of young democracies (centralization, clientelism, and powerful executives) shape government attention, responsiveness to public opinion, and the importance of elections in policy change. The first essay examines the dynamics of government attention and how the neopatrimonial nature …

Triggered Online System Re-Identification Applied To Model Predictive Control Using Gaussian Processes, Daniel Augusto Kestering

Graduate Theses, Dissertations, and Problem Reports (ETD)

Safety, product quality, enhanced performance, and increased profit all depend on the control of chemical and energy processes. However, operational issues can lead to control challenges, especially when processes are subject to disturbances during their operation. Process control methods work best when processes operate close to their designed operat- ing conditions, but lack of performance or other issues may occur when the process is far from such conditions. To overcome these challenges, in this dissertation, online model re- identification is proposed for Model Predictive Control (MPC). This involves reassessing the predictive model of an advanced controller, namely MPC, when re-identification …

Performance And Physiological Impacts Of Branched-Chain Amino Acid And Tryptophan Ratio Variations In Turkey Starter Diets Utilizing Concentrated Corn Proteins, Emily Blair Estanich

Graduate Theses, Dissertations, and Problem Reports (ETD)

In Chapter 2, a study was designed to evaluate the effects of varying dietary branched-chain amino acids (BCAA) ratio in corn and soybean meal-based turkey starter diets. The BCAA leucine, isoleucine, and valine are considered indispensable amino acids needed for energy and stimulation of muscle protein synthesis via the mammalian target of rapamycin (mTOR) pathway. Imbalanced BCAA ratios can lead to antagonism and degradation of limiting BCAA, particularly in diets with excess leucine. Concentrated corn proteins contain high levels of leucine and can alter BCAA requirements; however, crystalline BCAA may be added to correct these ratios. This study aimed to …

The Role Of Uric Acid In Metabolic Abnormalities Of Obesity, Andrew P. Giromini

Graduate Theses, Dissertations, and Problem Reports (ETD)

Uric acid (UA) is the single most tightly associated metabolite for obesity and type 2 diabetes. While the field varies on whether UA is causative or correlative of the metabolic dysfunction allied to obesity, these studies use different diets and animal models to make these claims. It is the goal of this dissertation to compare different diets commonly used in this research to delve deeper into the data and determine which diets induce elevated circulating UA levels as well as which diets also induce metabolic dysfunction. Early chapters of this dissertation examine the comparison of high fructose consumption, both in …

A Balancing Act: Microrna Mediated Insect-Bacterial Homeostasis And The Tsetse Fly, Mason Hubbard Lee

Graduate Theses, Dissertations, and Problem Reports (ETD)

Microbial symbioses are ubiquitous across all kingdoms of life with broad and diverse impacts on the evolution of species. The sum of all microbes living in, on, or otherwise in close association with a host form the microbiota. In some cases, the development of a stable microbial association seems to have been necessary for the specialization of diet, as can be observed in numerous insect species, especially wood-eating, sap-feeding, and blood-feeding organisms. For the medically and economically tsetse fly (family Glossinidae), the mutualistic bacteria Wigglesworthia glossinidia is required for proper reproduction and supplementation of nutrients that the fly does not …

Polylactic Acid (Pla) Containing Talc Microparticles And Amorphous Polyhydroxyalkanoates (Aphas) For Improved Barrier And Mechanical Properties In Food Packaging, Mohammed Alfaifi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Polylactic acid (PLA) is a biobased and compostable polymer that is increasingly being used as an alternative to petroleum-based, non-biodegradable polymers for single-use food packaging due to its environmental benefits. It is also commercially available in large quantities, and it can be processed like polyethylene. However, it has a higher water-vapor permeability (WVP) as compared to polyolefins and polyethylene terephthalate that are the incumbent materials. This results in a competitive disadvantage in employing PLA for packaging baked goods since the shelf life of the food is likely to be reduced. In the past, barrier properties of PLA were improved by …

Drosophila Parasitoids Go To Space: Unexpected Effects Of Spaceflight On Hosts And Their Parasitoids, Jennifer Chou, Johnny R. Ramroop, Amanda M. Saravia-Butler, Brian Wey, Matthew P. Lera, Medaya L. Torres, Mary Ellen Heavner, Janani Iyer, Siddhita D. Mhatre, Sharmila Bhattacharya, Shubha Govind

Publications and Research

While fruit flies (Drosophila melanogaster) and humans exhibit immune system dysfunction in space, studies examining their immune systems’ interactions with natural parasites in space are lacking. Drosophila parasitoid wasps modify blood cell function to suppress host immunity. In this study, naive and parasitized ground and space flies from a tumor-free control and a blood tumor-bearing mutant strain were examined. Inflammation-related genes were activated in space in both fly strains. Whereas control flies did not develop tumors, tumor burden increased in the space-returned tumor-bearing mutants. Surprisingly, control flies were more sensitive to spaceflight than mutant flies; many of their …
