A Comparative Analysis Of The Metabolism And Energetics Of Darters (Percidae), Emma Kirsten Kist

Theses, Dissertations and Capstones

Ecological niche theory suggests two species cannot live in the same ecological niche and differences should exist among species that appear to cohabitate. Variations in physiology and behavior that potentially enable species coexistence can be reflected in metabolism. This study investigated coexisting darter fishes by measuring the metabolism of greenside (Etheostoma blennioides) and variegate (E. variatum) darters over 48 h using intermittent-flow respirometry. Activity was analyzed using time-lapse videos. E. blennioides mean metabolic rate (154.64 ± SE 52.54 mg O2·kg-1 ·hr-1 ; n=14; p=0.0006) was significantly greater than and varied more than E. variatum’s mean rate (92.51 ± SE 32.70 …

An Ultrasonographic Analysis Of The Structures Of The Subacromial Space, As They Relate To The Postures Of Upper String Musicians, Elliot V. Smithson

Theses, Dissertations and Capstones

Background: The leading source of general population shoulder pain is subacromial impingement syndrome (SAIS) which can contribute to rotator cuff disease (RCD). 1 It has been reported that up to 12% of musicians end their musical career due to musculoskeletal injury.2 SAIS is a common source of shoulder pain in the bowing arm of upper string musicians.3 However, the mechanisms leading to shoulder pain in upper string musicians are not well known.

Purpose: The purpose of this study was to characterize aspects of the subacromial space anatomy while in standard playing positions of upper string musicians, specifically measurements …

Portrayals Of Gender In The Media: A Content Analysis Approach To Identifying Gender Oppression And Legitimation Of Patriarchy In Magazine Advertisements, Autumn M. O’Toole

Theses, Dissertations and Capstones

Advertisements are among the most pervasive forms of media. Portrayals of gender in advertisements constitute a significant subject of social research based on this pervasiveness and the influence that advertising media have on audiences. This influence is based on the notion that media is an institutional vehicle for ideas about products, lifestyles, and oppression. In this study, the institution of media is examined through an analysis of representations of patriarchy and gender oppression in media advertisements. The primary research question is: In what ways can we identify gender oppression and the support of hegemonic masculinity and systems of patriarchy in …

Electromyography Study Of Muscle Fatigue During Isometric Exercises In Swimmers And Non-Swimmers, Tiffany Aeling

Theses, Dissertations and Capstones

The use of electromyography (EMG) techniques offer strong evaluation of musculature fatigue during activity in different exercises. Studies show that EMG can be used to monitor fatigue patterns in muscles composing the upper extremities and thoracic areas of the human body by analyzing median frequency values. Advances in muscle fatigue research have been critical for improving rehabilitation programs for patients with musculoskeletal conditions. Despite these developments, many collegiate athletes are still at high risk for muscle injury on and off the playing field. Therefore, in order to help reduce injury numbers, it is important that current research focus on the …

Uncovering New Roles For The Aryl Hydrocarbon Receptor (Ahr) In Breast Cancer, Justin Kirk Tomblin

Theses, Dissertations and Capstones

The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that is responsive to many exogenous and endogenous ligands. AHR is of particular interest in cancer, and has been shown to play roles in tumor progression. As such, it has received growing attention as a possible chemotherapeutic target. Obesity increases the risk of breast cancer, complicates treatment of breast cancer, and stimulates the growth of larger, more aggressive mammary tumors. Many breast tumors in obese women are estrogen receptor (ER)-positive and, while targeting hormone receptors like ER is beneficial, many obese women see a recurrence of their cancer after standard …

Adult Neural Stem Cell Differentiation And Signaling Is Disrupted By Low-Level Silver Nanoparticle Exposure In Vitro, Robert Jefferson Cooper

Theses, Dissertations and Capstones

Silver nanoparticles (AgNP) are an emerging environmental contaminant with unique chemical and physical properties. They are utilized in products like medical dressings and children’s toys for their antimicrobial action. Though AgNP’s bioaccumulative nature and high-level toxicity are established, low-level effects from chronic exposure to AgNP-containing products and environmental AgNP remain unclear. This study uses adult neural stem cells, a model for neural cell function and neurodevelopment, to assess changes in cell differentiation and behavior following low-level AgNP exposure. In vitro, low-level AgNP produced dose- and timedependent formation of co-localized f-actin inclusions and β-catenin puncta. Neurite extension and arborization were also …

Appalachian Parent Perceptions Of Adhd Symptomology, Shaina Lee Meadows

Theses, Dissertations and Capstones

Attention-deficit/hyperactivity disorder (ADHD) is the most widely documented referral concern among children and adolescents referred to mental health practitioners. The current study examined Appalachian parents’ (N=68) knowledge of ADHD, accuracy in identifying ADHD symptoms, and treatment preferences. Findings of the survey indicate the majority of parents received no training on ADHD; however, most were able to recognize the majority of the signs of ADHD. Equally important, parents of children with ADHD and those who reported receiving some form of ADHD training demonstrated a negligible advantage in correctly identifying ADHD symptoms. Results, moreover, showed a significant preference for discipline as a …

Appalachian Teachers' Referral For Adhd In Contrast To Giftedness In Selected Vignettes, Alexandria Rose Mejia

Theses, Dissertations and Capstones

ADHD is the most widely diagnosed behavior disorder in children however, the nonstandardized nature of an ADHD evaluation can lead to misdiagnosis. Teachers often initiate referrals, though symptoms associated with ADHD can also be observed in gifted students. Appalachia has reported rates of ADHD that are much higher than the national average. It is therefore important that the factors that influence referral are better understood. This study hypothesized that priming to giftedness would reduce the likelihood that a teacher would refer for an ADHD evaluation in ambiguous vignettes and that teachers primed to consider giftedness will rate characteristics of ADHD …

Revision Of Polycotylid Plesioaur Systematics (Sauropterygia Plesiosauria) And Description Of The Axial Osteology Of A Juvenile Polycotylid, Donald Joseph Morgan Iii

Theses, Dissertations and Capstones

The polycotylids were a clade of plesiosaurs that proliferated during the Cretaceous period. Despite recent research efforts, evolutionary relationships among polycotylid species remain unresolved. In this study, a phylogenetic analysis incorporating a large taxon sampling from the Polycotylidae was used to parse out the evolutionary relationships among the taxa. The main focus was to assign two polycotylid specimens from the Wallace Ranch to a formal species. A study on the axial osteology of the juvenile Wallace Ranch polycotylid was also performed, as the development of the axial column of a polycotylid plesiosaur has been poorly understood and may have phylogenetic …

Hibernacula Site Selection Of The Eastern Box Turtle, Terrapene C. Carolina, In A West Virginia Population, Benjamin Owen Koester

Theses, Dissertations and Capstones

Eastern Box Turtles (Terrapene c. carolina) are a terrestrially hibernating reptile found throughout the eastern United States. Despite their prevalence, little, outside of anecdotal observations, is known about their hibernacula selection. This study examines if they preferentially select hibernacula locations, and if so, what characteristics they select in a West Virginia population. Over the course of two years, radio-tagged turtles (n=12) were followed into hibernation in Wayne County, WV. Upon entering hibernation, ~36 data point were collected in a grid-like fashion around the hibernacula, with an additional point collected at the hibernacula. At each point, seven variables were recorded: soil …

An Assessment Of West Virginia Watersheds Through The Use Of Geographic Information System (Gis), Nathan Thomas Hoxie

Theses, Dissertations and Capstones

Analysis of West Virginia Department of Environmental Protection (WVDEP) agency’s Stream Condition Index and habitat assessment data compared two cycles of data. Geographic Information System (GIS) was used to develop a kriging model to project scores. Scores were calculated for Hydrologic Unit Code (HUC) eight and ten using Zonal statistics. The Getis-Ord Gi Star was used to identify high and low value clusters. Land use and impervious surface data was gathered from the United States Geological Survey (USGS) to assess impacts to watersheds. The results for WVSCI and habitat assessment showed that there was an improvement between cycles. Negative WVSCI …

A Study Of Outcomes Based Educational Interventions And Moral Development Of Undergraduate College Students, Jay Christopher Robert Wildt

Theses, Dissertations and Capstones

Discussions regarding moral development and subsequent behavior are common in political and philosophical arenas. The consensus is that resolutions of moral dilemmas are best accomplished through careful deliberation and the use of principled moral reasoning. The purpose of this study was to examine changes in moral development in undergraduate college students who participated in an outcomes based education program. The study also investigated the influence of certain demographic and attribute variables on moral development within the same population.

This study examined extant data from 295 University of Charleston (UC) students who took the Defining Issues Test as freshmen and then …

Analyzing Pterosaur Ontogeny And Sexual Dimorphism With Multivariate Allometry, Erick Charles Anderson

Theses, Dissertations and Capstones

The relationships of pterosaurs have been previously inferred from observed traits, depositional environments, and phylogenetic associations. A great deal of research has begun to analyze pterosaur ontogeny, mass estimates, wing dynamics, and sexual dimorphism in the last two decades. The latter has received the least attention because of the large data set required for statistical analyses. Analyzing pterosaurs using osteological measurements will reveal different aspects of size and shape variation in Pterosauria (in place of character states) and sexual dimorphism when present. Some of these variations, not easily recognized visually, will be observed using multivariate allometry methods including Principle Component …

Attitudes Toward Complementary And Alternative Medicine, Miranda Lea Cobb

Theses, Dissertations and Capstones

Complementary and alternative medicine (CAM) usage has increased throughout the years, as many people are becoming interested in using less conventional interventions for common illnesses. As a whole, CAM encompasses any practice used to treat an illness or disorder that does not fall under the category of traditional medicine. CAM interventions not only treat the physical aspects of health, but as clinicians are beginning to realize, these interventions may also be effective in treating psychological problems, most notably anxiety and depression. This research focused on attitudes toward CAM for psychological disorders. I examined participants’ attitudes about the use of CAM …

Bodybuilding Is An Art And Your Body Is The Canvas: An Examination Of Bodybuilders And The Built Body, Caitlin Greaf

Theses, Dissertations and Capstones

This study examines the bodybuilding community by conducting interviews and watching the bodybuilding documentaries Pumping Iron, Pumping Iron II, and Generation Iron. Bodybuilders’ performance of the body is not solely acted just on stage for competitions. Rather, bodybuilders are continuously redefining limitations of what we determine a ‘normal’ body looks like. By using the concept of the gaze, I analyze bodybuilders’ bodies as an oddity on and off stage (Mulvey, 1989). The oddity of their body transforms the space it takes up into a stage for entertainment. I then examine gender performances of female and male bodybuilders within the traditionally …

Testing The Efficacy Of Anuran Callback Surveys, Matthew S. Grisnik

Theses, Dissertations and Capstones

Monitoring programs often suffer from imperfect detection resulting in skewed population estimates, biased estimates of changes in occupancy over time, and can result in an underestimated proportion of area occupied (PAO) by a species. To increase the detection probability, researchers must increase sampling both spatially and temporally. Callback surveys are an active form of sampling that have been used to monitor many avian and mammal species. During callback surveys, the call of a conspecific male is projected with the intention of increasing probability of detection by eliciting a response from territorial males. These methods work for organisms that establish breeding …

3,5-Dichloroaniline: Biotransformation And Mechanistic Aspects Of Nephrotoxicity In Vitro, Christopher Robert Racine

Theses, Dissertations and Capstones

Chlorinated anilines have been used as important chemical intermediates in the production of a wide variety of pharmaceutical, industrial, and agricultural products. Exposure to chloroanilines can arise in both occupational and environmental settings and can lead to toxicity to multiple organs, including the kidney. Previous studies have established that of the mono- and dichlorinated anilines, 3,5-dichloroaniline (3,5-DCA) possesses the most nephrotoxic potential both in vitro and in vivo. However, little is known concerning the role of renal metabolism in nephrotoxicity. The studies presented in the following dissertation are the first to explore the toxicity, metabolism, and bioactivation of 3,5-DCA in …

A Coprological Survey Of Golden Mantled Howler Monkeys (Alouatta Palliata Palliata) In The Osa Peninsula, Costa Rica, Jess M. Conatser

Theses, Dissertations and Capstones

Interactions between free-ranging primates and their associated parasitic forms continue to be a point of interest in ecology for several reasons. External and internal parasitism is not atypical for wild populations of primates, and the repercussions of these relationships can range from benign to life-threatening and capable of altering the structure of naturally occurring groups. The ecological relationship between the golden mantled howler monkey (Alouatta palliata palliata) and its host-specific ectoparasite, the howler monkey bot fly (Alouattamyia baeri) poses significant potential detriment to the overall body quality and success of the host primate. A. p. palliata has also been recorded …

Ploidy Distribution Of The Harmful Bloom Forming Macroalgae Ulva Spp. In Narragansett Bay, Rhode Island, Usa, Using Flow Cytometry Methods, Elaine E. Potter, Carol S. Thornber, John-David Swanson, Malcolm Mcfarland

Biological Sciences Faculty Publications

Macroalgal blooms occur worldwide and have the potential to cause severe ecological and economic damage. Narragansett Bay, RI is a eutrophic system that experiences summer macroalgal blooms composed mostly of Ulva compressa and Ulva rigida, which have biphasic life cycles with separate haploid and diploid phases. In this study, we used flow cytometry to assess ploidy levels of U. compressa and U. rigida populations from five sites in Narragansett Bay, RI, USA, to assess the relative contribution of both phases to bloom formation. Both haploid gametophytes and diploid sporophytes were present for both species. Sites ranged from …

Sphere Representations, Stacked Polytopes, And The Colin De Verdière Number Of A Graph, Lon Mitchell, Lynne Yengulalp

Mathematics Faculty Publications

We prove that a k-tree can be viewed as a subgraph of a special type of (k + 1)- tree that corresponds to a stacked polytope and that these “stacked” (k + 1)-trees admit representations by orthogonal spheres in R k+1. As a result, we derive lower bounds for Colin de Verdi`ere’s µ of complements of partial k-trees and prove that µ(G) + µ(G) > |G| − 2 for all chordal G.

Interleukin-6 Is A Risk Factor For Atrial Fibrillation In Chronic Kidney Disease: Findings From The Cric Study., Richard L. Amdur, Monica Mukherjee, Alan Go, Ian R Barrows, Ali Ramezani, Jun Shoji, Dominic S. Raj, +13 Additional Authors

Surgery Faculty Publications

Atrial fibrillation (AF) is the most common sustained arrhythmia in patients with chronic kidney disease (CKD). In this study, we examined the association between inflammation and AF in 3,762 adults with CKD, enrolled in the Chronic Renal Insufficiency Cohort (CRIC) study. AF was determined at baseline by self-report and electrocardiogram (ECG). Plasma concentrations of interleukin(IL)-1, IL-1 Receptor antagonist, IL-6, tumor necrosis factor (TNF)-α, transforming growth factor-β, high sensitivity C-Reactive protein, and fibrinogen, measured at baseline. At baseline, 642 subjects had history of AF, but only 44 had AF in ECG recording. During a mean follow-up of 3.7 years, 108 subjects …

Mutational Profiles Reveal An Aberrant Tgf-Β-Cea Regulated Pathway In Colon Adenomas., Jian Chen, Gottumukkala S Raju, Wilma Jogunoori, Shoujun Gu, Lopa Mishra, + 27 More

Surgery Faculty Publications

Mutational processes and signatures that drive early tumorigenesis are centrally important for early cancer prevention. Yet, to date, biomarkers and risk factors for polyps (adenomas) that inordinately and rapidly develop into colon cancer remain poorly defined. Here, we describe surprisingly high mutational profiles through whole-genome sequence (WGS) analysis in 2 of 4 pairs of benign colorectal adenoma tissue samples. Unsupervised hierarchical clustered transcriptomic analysis of a further 7 pairs of adenomas reveals distinct mutational signatures regardless of adenoma size. Transitional single nucleotide substitutions of C:G>T:A predominate in the adenoma mutational spectrum. Strikingly, we observe mutations in the TGF-β pathway …

Vitamin D Deficiency Promotes Liver Tumor Growth In Transforming Growth Factor-Β/Smad3-Deficient Mice Through Wnt And Toll-Like Receptor 7 Pathway Modulation., Jian Chen, Lior H Katz, Nina M Muñoz, Shoujun Gu, Ji-Hyun Shin, Lopa Mishra, +13 Additional Authors

Surgery Faculty Publications

Disruption of the TGF-β pathway is associated with liver fibrosis and suppression of liver tumorigenesis, conditions associated with low Vitamin D (VD) levels. However, potential contributions of VD to liver tumor progression in the context of TGF-β signaling remain unexplored. Our analyses of VD deprivation (VDD) in in vivo models of liver tumor formation revealed striking three-fold increases in tumor burden in Smad3(+/-) mice, with a three-fold increase in TLR7 expression compared to controls. ChIP and transcriptional assays confirm Smad3 binding at two TLR7 promoter SBE sites. Molecular interactions between TGF-β pathway and VDD were validated clinically, where an absence …
