Lead Exposure Of North American Raptors, Vincent A. Slabe

Graduate Theses, Dissertations, and Problem Reports (ETD)

Lead is an anthropogenic threat to terrestrial wildlife, has no physiological benefits, and is considered a neurotoxin. Legislation adopted in many developed countries restricts the uses of lead in consumer and industrial products such as pipe fittings, petrol, paint, and shot for use in waterfowl hunting. However, lead is currently categorized by the United States (US) government as a critical metal and common uses of lead still persist in North America. These include the use of rifle ammunition, shot in upland gamebird hunting, and fishing sinkers. Lead is also a by-product of multiple industrial operations including smelters, coal power plants, …

The Effects Of Obesity, Chronic Stress, And Exercise On Pancreatic Health, Abigail Tice

Graduate Theses, Dissertations, and Problem Reports (ETD)

Obesity is concomitant with hyperglycemic conditions, increased proinflammatory cytokines, and increased oxidative stress. Under hyperglycemia, thioredoxin interacting protein (TXNIP) is increased and causes increased oxidative stress and pancreatic b-cell apoptosis. Chronic stress is associated with increased glucocorticoid levels and a proinflammatory environment. The purpose of this study was to examine the effects of obesity, chronic stress, and exercise on pancreatic health.

Lean Zucker Rats (LZRs) and Obese Zucker Rats (OZRs) were randomly assigned to four groups: 1) sedentary controls (C: n=8 per); 2) unpredictable chronic mild stress (UCMS) (S: n=8); 3) exercise (E: n=8); and 4) combined UCMS and exercise …

However, teachers have continued to identify barriers affecting delivery related to professional development opportunities, learning environment, and experiences in practice. An understanding of the connection between these experiences and their impact on teacher change is needed.

Purpose: The purpose of this study was to investigate teachers’ perceptions of specific factors that have influenced their continued implementation of classroom PA. This study provides insight into the teacher perceptions, and aims to identify connections among orientation to learning and …

Health Literacy And Family Factors In The Transition To Adult Care In Adolescents With Type I Diabetes, Ellen M. Manegold

Graduate Theses, Dissertations, and Problem Reports (ETD)

Successful management of type 1 diabetes (T1DM) in adolescence involves multiple daily tasks, developmental changes, and the expectation of transition to an adult provider. Health literacy is one variable to consider in the context of transition, as studies have demonstrated the correlation of parental health literacy with health behaviors and outcomes, yet not studied adolescent health literacy in T1DM. Family factors (e.g., management responsibility, diabetes-specific family conflict, parental support) also are important to behavior and health outcomes in adolescents with T1DM. Study aims were to: 1) examine the association of adolescent health literacy to transition readiness and health outcome in …

The purpose of this study is to examine the changes in the politics of health policy which opened the door to women’s health care as an important feature of health politics. Thus, my research is motivated by three …

Investigation Of Bovine Conceptus Galectins And The Effect Of Bovine Conceptus Secretory Proteins On The Endometrial Epithelial Transcriptome, Heather Lynn Baldwin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Pregnancy loss in cattle is greatest in the first 30 days of gestation. Near d15 of gestation, bovine conceptuses elongate and express LGALS1, an immunosuppressive glycan-binding protein believed to be essential for implantation. However, other members of the bovine galectin family, including LGALS3, LGALS4, LGALS7, LGALS8, LGALS9 and a galectin-13-like gene (LGALS13L), also may be expressed by the elongating conceptus. Therefore, galectin expression in elongating, d16 bovine conceptuses and intercaruncular endometrium as well as elongating, d14 ovine conceptuses and intercaruncular endometrium was assessed by RT-qPCR. Angus heifer and Texel ewes underwent estrous cycle synchronization and either inseminated or not bred. …

A self-report survey was developed, using Likert-type scales, consisting of 32 items, including standardized, psychometrically-tested instruments. The survey was administered to 108 adult outpatients who reported to the West Virginia University …

Factors Related To Collaborative Willingness In Surrogate Decision-Making Situations From The West Virginia Post., Rachael Spalding

Graduate Theses, Dissertations, and Problem Reports (ETD)

If a patient becomes unable to adequately express preferences for medical care, another individual called a “surrogate” may be consulted to make treatment decisions. Surrogates may be asked to indicate patient preferences on the Physician Order for Scope of Treatment (POST), a new type of advance directive completed with patients who are estimated to have less than one year left to live. Research from the shared decision-making literature indicates that collaboration can be a valuable means of enhancing patient satisfaction with their decisions. The current study examined how certain psychological and demographic variables predicted the extent to which participants desired …

Shame And Guilt: The Good, The Bad, And The Ugly, Raika Sadeghein

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the past few decades, we have witnessed a growing body of literature on emotions in the consumer behavior domain. Emotions are defined as “mental states of readiness that arise from appraisals of events or one’s own thoughts” (Bagozzi, Gopinath, & Nyer, 1999, p. 184). Marketers have examined the role of emotions as stimuli, mediators, moderators, and responses to the environment. The broad topic of emotions includes subtopics such as impact of emotions on consumption, attitudes, and behavioral intentions, emotional responses to market stimuli, and the impact of emotions on cognition. However, although the study of emotions is pivotal to …

Compound-Specific Isotope Analysis Of Amino Acids In Biological Tissues: Applications In Forensic Entomology, Food Authentication And Soft-Biometrics In Humans, Mayara Patricia Viana De Matos

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this work we demonstrate the power of compound-specific isotope analysis (CSIA) to analyze proteinaceous biological materials in three distinct forensic applications, including: 1) linking necrophagous blow flies in different life stages to their primary carrion diet; 2) identifying the harvesting area of oysters for food authentication purposes; and 3) the ability to predict biometric traits about humans from their hair.

In the first application, we measured the amino-acid-level fractionation that occurs at each major life stage of Calliphora vicina (Robineau-Desvoidy) (Diptera: Calliphoridae) blow flies. Adult blow flies oviposited on raw pork muscle, beef muscle, or chicken liver. Larvae, pupae …

The Food Bank Fix: Hunger, Capitalism And Humanitarian Reason, Joshua David Lohnes

Graduate Theses, Dissertations, and Problem Reports (ETD)

Drawing on a five-year institutional ethnography of Humanitarian Food Networks (HFNs) in West Virginia, this dissertation explores the moral, political and economic place of the food bank in the corporate environmental food regime. I develop the concept of the food bank fix to theorize the paradoxical relationships between the state, the shadow state, food corporations, local charities and food banks that tie HFNs across the United States together through humanitarian reason. I argue that food banks damp the grinding contradictions of a society awash in food surpluses even as a significant proportion of the population remains at risk of hunger. …

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation is an empirical investigation of student level observations of 11 cohorts of first-time full-time freshmen from a public, land-grant, research university in Appalachia. Complete with student financial aid offerings, socioeconomic status, and pre-college academic characteristics such as standardized test scores and high school GPA, I investigate the data to examine institutional behavior constrained by resource dependence. The variable of interest is institutional financial aid. Institutional financial aid awards are monetary concessions presented to students as a means to discount the overall price a student pays to enroll. As institutional aid is a direct mechanism through which the institution …

Systematic Control Of Aged Skeletal Muscle Following High-Intensity Stretch-Shortening Contraction Exercise Training: Epigenomic Regulation And Signaling Factors Underpinning Adaptation, Marshall Alan Naimo Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

Sarcopenia, the age-related decline in skeletal muscle mass, results in a loss of strength and functional capacity, which subsequently increases the risk of disease, disability, frailty, and all-cause mortality. Exercise is known to be an efficacious paradigm for improving health and attenuating or preventing many chronic diseases. For the previous two decades, our laboratory has established an in vivo rodent dynamometer model to explore the effects of various skeletal muscle training paradigms following stretch-shortening contractions (SSCs).The responses tohigh-intensity resistance-type exercise training (RTET) using this physiological model ranges from adaptation, characterized by enhanced skeletal muscle performance along with increased muscle mass, …

Quantifying Human Biological Age: A Machine Learning Approach, Syed Ashiqur Rahman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Quantifying human biological age is an important and difficult challenge. Different biomarkers and numerous approaches have been studied for biological age prediction, each with its advantages and limitations. In this work, we first introduce a new anthropometric measure (called Surface-based Body Shape Index, SBSI) that accounts for both body shape and body size, and evaluate its performance as a predictor of all-cause mortality. We analyzed data from the National Health and Human Nutrition Examination Survey (NHANES). Based on the analysis, we introduce a new body shape index constructed from four important anthropometric determinants of body shape and body size: body …

Kidney Ailment Prediction Under Data Imbalance, Ranaa Mahveen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Chronic Kidney Disease (CKD) is the leading cause for kidney failure. It is a global health problem affecting approximately 10% of the world population and about 15% of US adults. Chronic Kidney Diseases do not generally show any disease specific symptoms in early stages thus it is hard to detect and prevent such diseases. Early detection and classification are the key factors in managing Chronic Kidney Diseases.

In this thesis, we propose a new machine learning technique for Kidney Ailment Prediction. We focus on two key issues in machine learning, especially in its application to disease prediction. One is related …

Improving Broiler Performance Utilizing Modern Feed Additives, Niles Rourke Ridgeway

Graduate Theses, Dissertations, and Problem Reports (ETD)

Modern broiler production strives to make modest improvements regarding broiler performance. This remains a goal as global population increases thusly increasing the quantity of an affordable, high quality source of protein. In recent years, an added stressor to achieving prior goals is mostly related to consciousness of environmental and consumer health. For decades, integrators have utilized minimal amounts of antibiotics as a barrier to most pathogens affecting the microbiome of a broiler’s gastrointestinal tract. Regulatory efforts have now prohibited most of previous sub-therapeutic medicine and started an in-depth scope of broiler gut health and interaction with antibiotic alternatives. In an …

The Effects Hot Water Kill Time Has On Dna Degradation And Str Profiling From Lucilia Sericata (Diptera: Calliphoridae) Crop Contents, Nicholas Alexander Haas

Graduate Theses, Dissertations, and Problem Reports (ETD)

he use of entomological specimens as a source of forensic DNA evidence has been studied since the late 20th century. Currently as it stands, to preserve both the minimum postmortem interval (mPMI) and DNA evidence within fly larvae, two standards of preservation exist. For mPMI, the use of hot water kill with near-boiling water is used to fix larvae size for accurate age estimation. For DNA evidence, the standard technique of preservation is submersion in 70% ethanol. To help reduce the number of standard preservation techniques for practitioners, this study assessed the feasibility of the hot water kill preservation technique …

The Acute Effect Of Propanil On Reproductive Hormones, Ovarian Gene Expression And Splenic Cells In C57bl/6 Female Mice, Malia Danielle Berg

Graduate Theses, Dissertations, and Problem Reports (ETD)

Earlier evidence indicates exposure to propanil, a post-emergent herbicide used on rice and wheat fields, increases the number of antibody-secreting cells (ASC) in the spleen of mice after immunization with heat-killed Streptococcus pneumoniae (HKSP, 2x10⁸ CFU). Interestingly, an intact hypothalamic-pituitary-gonadal (HPG) axis is required for this immune response assessed on day 7-10 after immunization in female mice. Hence, an overarching premise is that propanil arbitrates the connection between the reproductive and immune system by altering the concentration of hormones involved in the HPG axis, which may then affect the populations of splenic cells. Hypotheses were tested with C57Bl/6 female …

Caregiver Selection Of Treatments For Their Child With Autism, Amy Kurowski-Burt

Graduate Theses, Dissertations, and Problem Reports (ETD)

This project was completed to understand what treatments caregivers are selecting for their child with autism and why treatments were selected and discontinued. Caregivers of children with autism participated in a mixed methods study. An online survey was completed (N=127) to identify treatments used for their child. Interviews were completed (n=14) to understand why treatments were selected and discontinued. Selection of medical, dietary, therapeutic, complimentary/ alternative medicine, community-based, behavioral, and educational treatments were mostly influenced by recommendations of others. Caregivers reported discontinuing because relationships and professionalism were lacking between provider and family. Providers must consider all the variables that influence …

Differentiating Human Populations Based On K-Mer Classification Of Hand Bacteria, Thrisha Doppala

Graduate Theses, Dissertations, and Problem Reports (ETD)

Bacterial communities found in and on the human body are not only used in studying human health conditions but are also effective in differentiating individuals due to their distinct profiles. Human palm regions harbor relatively more diverse bacterial communities and are indicative of population groups, life styles, geographic locations, age groups and health conditions. Sequences extracted from hypervariable region V3 of the 16S rRNA bacterial gene of hand bacterial samples from 9 different population groups were classified into Operational Taxonomic Units (OTU) with GreenGenes reference taxonomy using RDP (Ribosomal Database Project) classifier. Frequencies of identified OTUs were used to study …

Wintering American Black Duck Ecology Of Central Appalachia, Sara E. Yannuzzi

Graduate Theses, Dissertations, and Problem Reports (ETD)

The American black duck (Anas rubripes) is a species of dabbling duck found only in the northeastern part of North America, and widely hunted until its decline. Since the 1950s, the total population has decreased by 53%. Habitat degradation and decline of wintering and breeding wetlands, historic overharvest, and interactions with the mallard (A. platyrhynchos) are attributed as some of the main causes of the black duck population’s decrease. Many policies and taxa- and habitat-specific joint ventures have since been created to aid in studying and improving North American wetlands and black duck populations throughout both their breeding and wintering …

Characterization Of Kndy Neuronal Activity In Gilts: Distribution And Effect Of A Progestin, Ashley Nicollette Lindo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Puberty is a process that incorporates a large array of both external factors and internal signals. The endocrinology of puberty has been studied in a number of mammalian species and typically depends upon an increase in hypothalamic secretion of gonadotropin releasing hormone (GnRH). Neural inputs regulating GnRH secretion during the pubertal process are not completely understood. In the past decade, attention has focused on the role for a particular set of neurons located in the arcuate nucleus (ARC) of the hypothalamus. They have been named KNDy neurons because they coexpress kisspeptin, neurokinin B (NKB) and dynorphin and have been shown …
