Ancestral Variation And The Evolution Of Sneaking Behavior In The Adaptive Radiation Of Threespine Stickleback (Gasterosteus Aculeatus L.), Katherine A. Shaw

Doctoral Dissertations

Behavior, a group of highly plastic and responsive phenotypic traits, has been characterized as having the potential to both drive and inhibit evolutionary change within populations. The Threespine Stickleback radiation (Gasterosteus aculeatus L.) is a model system that demonstrates the vital role environment plays in behavioral evolution – with multiple colonizations of variable freshwater habitats by ancestral oceanic metapopulations producing the behaviorally diverse populations observable today. Here I characterize both inter- and intra-population variation in sneaking behavior – an inconspicuous mating tactic used by threespine males to gain fertilizations as an alternative to courtship behavior. I present evidence for …

The Effect Of Topical Estriol On Human Inner Foreskin, Cheryl L. Bell

Doctoral Dissertations

Human immunodeficiency virus (HIV) is a global health concern prompting an urgent need to develop simple, effective, economical preventive measures. The research described in this thesis evaluated the potential for topical estriol to induce keratinization of the inner foreskin, the primary site of HIV entry in uncircumcised males.

We found that topical estriol can induce keratinization of the human inner foreskin by up-regulating the production of keratins per cell, and not through increased skin proliferation. Furthermore, the quantity and position of HIV target cells in the foreskin were not adversely affected by the treatment.

Estrogen receptors (ERs) are transcription factors …

Biofilm Microenvironment Analysis Systems For Medicine And Agriculture, Jinzi Deng

Doctoral Dissertations

Biofilms are aggregated bacteria embedded in extracellular polymeric substances (EPS). Biofilms are the dominant growth form of bacteria in most natural environments, and are also important in many industrial and in vivo settings. The function of a biofilm system is inherently different from the function of the same cells dispersed in liquid culture. Existing methods to study biofilm either do not maintain the essential biofilm architecture or do not capture the dynamic nature of their responses. This research describes the development of a set of biofilm microenvironment analysis systems that maintain the essential micro-scale structure of biofilms. These systems are …

Self-Regulation In The Iep Classroom: Developing Lifelong English Language Proficiency, Jeannie Slayton

Doctoral Dissertations

Although students in Intensive English Programs (IEPs) acknowledge the importance of acquiring academic English skills, their primary concern is obtaining an acceptable Test of English as a Foreign Language (TOEFL) score. In order to continue improving their English skills beyond the last English class, learners need to have the capability of self-regulating their own learning. The problem for IEP teachers is fostering self-regulation in students who tend to be exam-oriented learners.

The conceptual framework for this qualitative study was constructed by examining and synthesizing research from the fields of adult education and educational psychology. This framework informed the interview protocol, …

Utilizing Computer Programming To Analyze Post-Tonal Music: A Segmentation And Contour Analysis Of Twentieth-Century Music For Solo Flute, Kate Sekula

Doctoral Dissertations

Two concepts will be synthesized in this dissertation: 1) the creation of accessible computer applications for melodic segmentation and contour reduction and 2) the application of segmentation and contour reduction to analyze twentieth-century post-tonal works for unaccompanied flute. Two analytical methodologies have been chosen: James Tenney and Larry Polanski's Gestalt segmentation theory and Robert Schultz's refinement of Robert Morris's contour reduction algorithm. The investigation also utilizes Robert Schultz's concept of diachronic-transformational analysis in conjunction with contour reduction. While both segmentation and contour reduction are invaluable analytical tools, they are meticulous and time-consuming processes. Computer implementation of these algorithmic procedures produces …

Culturally Relevant Esl Pedagogy For California Community College Teacher Educators, Jeff Moran

Master's Projects and Capstones

Demographics in the US are changing rapidly. The current white majority will fall below 50% of the total population by 2060. This shift has already occurred in California, where Latino/as are the largest single ethnic group in the state. California community college student populations reflect this reality, as at least 65% are students of color and 25% are immigrants to the US. California community college ESL instructors are often involved in teaching immigrants and non-native English speakers of color. In contrast to the student body, California community college teacher demographics remain overwhelmingly homogenous, as over 82% of full and part-time …

Oligomerization, Conformational Stability And Thermal Unfolding Of Harpin, Hrpzpss And Its Hypersensitive Response-Inducing C-Terminal Fragment, C-214-Hrpzpss., Pradip K Tarafdar, Lakshmi Vasudev Vedantam, Rajeshwer S Sankhala, Pallinti Purushotham, Appa Rao Podile, Musti J Swamy

Department of Biochemistry and Molecular Biology Faculty Papers

HrpZ-a harpin from Pseudomonas syringae-is a highly thermostable protein that exhibits multifunctional abilities e.g., it elicits hypersensitive response (HR), enhances plant growth, acts as a virulence factor, and forms pores in plant plasma membranes as well as artificial membranes. However, the molecular mechanism of its biological activity and high thermal stability remained poorly understood. HR inducing abilities of non-overlapping short deletion mutants of harpins put further constraints on the ability to establish structure-activity relationships. We characterized HrpZPss from Pseudomonas syringae pv. syringae and its HR inducing C-terminal fragment with 214 amino acids (C-214-HrpZPss) using calorimetric, spectroscopic and microscopic approaches. Both …

Considerations of how gender-related factors influence smoking first appeared over 20 years ago in the work of critical and feminist scholars. This scholarship highlighted the need to consider the social and cultural context of women's tobacco use and the relationships between smoking and gender inequity. Parallel research on men's smoking and masculinities has only recently emerged with some attention being given to gender influences on men's tobacco use. Since that time, a multidisciplinary literature addressing women and men's tobacco use has spanned the social, psychological and medical sciences. To incorporate these gender-related factors into tobacco reduction and cessation interventions, our …

Potential Effects Of Elevated Co2 On Pitcher Plant Nectar Composition, Prey Capture, And Inquiline Communities, Deirdre Courtney

Honors Theses

Human activities such as fossil fuel burning and deforestation have contributed significantly to the increasing levels of CO₂ in the atmosphere since the industrial revolution. Under the IPCC A1FI emission scenario, we are expected to reach levels as high as 1000 ppm by the end of the century. On average, C₃ plants experience a 27% increase in carbon to nitrogen (C:N) ratio under elevated CO₂. As a result, C₃ plants typically exhibit an increase in carbon-based secondary compounds. Carnivorous plants are a rare type of C₃ plant that has adapted to survive in low …

The Role Of Chemokine Receptor Cxcr7 With Egfr In Breast Cancer Cell Proliferation, Nicole Salazar

Open Access Dissertations

Recent advances have revealed a significant contribution of chemokines and their receptors in tumor growth, survival after chemotherapy and organ-specific metastasis. The CXC chemokine receptor-7 (CXCR7) is the latest chemokine receptor implicated in cancer. Although over expressed in breast cancer cell lines and tumor tissues, its mechanism of action in breast cancer (BrCa) growth and metastasis was not clear. Studies in other cancers have implicated CXCR7 in cell proliferation, anti-apoptotic activity and cell-cell adhesion. The present study was initiated to examine the pattern of CXCR7 expression and its role in regulation of growth signaling in breast cancer. The contribution of …

Genome-Wide Analysis Of Drosophila Circular Rnas Reveals Their Structural And Sequence Properties And Age-Dependent Neural Accumulation, Sarah Olson, Brenton R. Graveley

UCHC Articles - Research

Circularization was recently recognized to broadly expand transcriptome complexity. Here, we exploit massive Drosophila total RNA-sequencing data, >5 billion paired-end reads from >100 libraries covering diverse developmental stages, tissues, and cultured cells, to rigorously annotate >2,500 fruit fly circular RNAs. These mostly derive from back-splicing of protein-coding genes and lack poly(A) tails, and the circularization of hundreds of genes is conserved across multiple Drosophila species. We elucidate structural and sequence properties of Drosophila circular RNAs, which exhibit commonalities and distinctions from mammalian circles. Notably, Drosophila circular RNAs harbor >1,000 well-conserved canonical miRNA seed matches, especially within coding regions, and coding …

P53 And Cancer-Associated Sialylated Glygans Are Surrogate Markers Of Cancerization Of The Bladder Associated With Schistosoma Haematobium Infection, Julio Santos, Elisabete Fernandes, Jose Alexandre Ferreira, Luis Lima, Ana Tavares, Andreia Peixoto, Beatriz Parreira, Jose Manuel Correia Da Costa, Paul J. Brindley, Carlos Lopes, Lucio L. Santos

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background

Bladder cancer is a significant health problem in rural areas of Africa and the Middle East where Schistosoma haematobium is prevalent, supporting an association between malignant transformation and infection by this blood fluke. Nevertheless, the molecular mechanisms linking these events are poorly understood. Bladder cancers in infected populations are generally diagnosed at a late stage since there is a lack of non-invasive diagnostic tools, hence enforcing the need for early carcinogenesis markers.

Methodology/Principal Findings

Forty-three formalin-fixed paraffin-embedded bladder biopsies of S. haematobium-infected patients, consisting of bladder tumours, tumour adjacent mucosa and pre-malignant/malignant urothelial lesions, were screened for bladder …

Sociology Faculty Research

The lack of progress in reducing health disparities suggests that new approaches are needed if we are to achieve meaningful, equitable, and lasting reductions. Current scientific paradigms do not adequately capture the complexity of the relationships between environment, personal health and population level disparities. The public health exposome is presented as a universal exposure tracking framework for integrating complex relationships between exogenous and endogenous exposures across the lifespan from conception to death. It uses a social-ecological framework that builds on the exposome paradigm for conceptualizing how exogenous exposures “get under the skin”. The public health exposome approach has led our …

Regulation Of Three Nitrogenase Gene Clusters In The Cyanobacterium Anabaena Variabilis Atcc 29413, Teresa Thiel, Brenda Pratte

Biology Department Faculty Works

The filamentous cyanobacterium Anabaena variabilis ATCC 29413 fixes nitrogen under aerobic conditions in specialized cells called heterocysts that form in response to an environmental deficiency in combined nitrogen. Nitrogen fixation is mediated by the enzyme nitrogenase, which is very sensitive to oxygen. Heterocysts are microxic cells that allow nitrogenase to function in a filament comprised primarily of vegetative cells that produce oxygen by photosynthesis. A. variabilis is unique among well-characterized cyanobacteria in that it has three nitrogenase gene clusters that encode different nitrogenases, which function under different environmental conditions. The nif1 genes encode a Mo-nitrogenase that functions only in heterocysts, …

Exploring The Intersection Between Folk And Conventional Medicine In Albany, Kentucky, Chloe J. Brown

Mahurin Honors College Capstone Experience/Thesis Projects

Approximately 60% of patients surveyed (in Albany, KY) practice folk medicine, which suggests that a significant segment of the population may practice folk medicine. Patients typically use folk medical treatments concurrently with conventional medical treatments; while the interaction of these treatments is generally innocuous or positive, folk medical treatments can sometimes be harmful, lead to negative interactions with other drugs prescribed by a conventional medical professional. Since folk medicine and conventional medicine frequently interact, it is important for medical professionals to be aware of and address folk medical practices in a conventional medical environment. In order to better address folk …

Spatial Variation In The Littoral Vertebrate Community Of A Reservoir Relative To Physical And Biological Gradients, Nathan Ruhl, Jessica J. Soski, Willem M. Roosenburg

College of Science & Mathematics Departmental Research

Reservoirs possess gradients in conditions and resources along their long (deep-shallow) axis, but the response of littoral vertebrates (fish and turtles) to these gradients is poorly understood. We have quantified the littoral vertebrate communities throughout a small reservoir in Southeastern Ohio during July and August using traps, and related community composition to environmental variables using NMDS ordination. Ordination revealed that fish and turtles were broadly separated in ordination space, and three distinctly different environmental gradients were significantly associated with the underlying observed species abundances. Observed turtle abundance was explained by measurements of bathymetry, turbidity, and benthic resources, but none of …

"If You Have No Men, You Have No War!”: A Critical Overview Of Edgar Selwyn's Men Must Fight (1933), Ryan R. Copping

Cinesthesia

ABSTRACT: Edgar Selwyn’s Men Must Fight (1933) is an obscure yet culturally relevant science fiction drama. An atypical film from its era, the movie has an unusual subject for a Classical Hollywood film- gender socialization. The film didactically argues that wars are inevitable because men are inherently violent, and that, conversely, world peace world occur if women were in power, a possibility that appears to be regrettably impossible. It is also remarkably prescient in predicting that World War II would begin in 1940, only one year off from the German invasion of Poland. This paper combines a close content analysis …

Ifn-Γ Causes Aplastic Anemia By Altering Hematopoietic Stem/Progenitor Cell Composition And Disrupting Lineage Differentiation, Fan Ching Lin, Megan Karwan, Bahara Saleh, Deborah L. Hodge, Tim Chan, Kimberly C. Boelte, Jonathan R. Keller, Howard A. Young

United States Public Health Resources

Aplastic anemia (AA) is characterized by hypocellular marrow and peripheral pancytopenia. Because interferon gamma (IFN-γ) can be detected in peripheral blood mononuclear cells of AA patients, it has been hypothesized that autoreactive T lymphocytes may be involved in destroying the hematopoietic stem cells. We have observed AA-like symptoms in our IFN-γ adenylate-uridylate-rich element (ARE)-deleted (del) mice, which constitutively express a low level of IFN-γ under normal physiologic conditions. Because no T-cell autoimmunity was observed, we hypothesized that IFN-γ may be directly involved in the pathophysiology of AA. In these mice, we did not detect infiltration of T cells in bone …

The major histocompatibility complex (MHC) is a dynamic genome region with an essential role in the adaptive immunity of vertebrates, especially antigen presentation. The MHC is generally divided into subregions (classes I, II and III) containing genes of similar function across species, but with different gene number and organisation. Crocodylia (crocodilians) are widely distributed and represent an evolutionary distinct group among higher vertebrates, but the genomic organisation of MHC within this lineage has been largely unexplored. Here, we studied the MHC region of the saltwater crocodile (Crocodylus porosus) and compared it with that of other taxa. We characterised genomic clusters …

Changes In Coral Community Composition At Devil's Crown, Galapagos Islands, Ecuador: A 7,700 Year Perspective, Katharine Jane Hendrickson

HCNSO Student Theses and Dissertations

Coral mortality caused by El Niño–Southern Oscillation (ENSO) activity and its related disturbances has been researched throughout the Eastern Pacific. In the past three decades, disturbances related to the El Niño–Southern Oscillation (ENSO) have been shown to influence coral growth in the Eastern Pacific. In the Galápagos Islands, Ecuador, more than 97% of corals experienced mortality after the severe 1982-1983 ENSO episode. However, two of the most dominant coral species found in a coral community adjacent to Devil’s Crown; Psammocora stellata and Diaseris distorta survived this severe ENSO event. By reconstructing sediment cores of the coral community, this study assessed …

Transceptors At The Boundary Of Nutrient Transporters And Receptors: A New Role For Arabidopsis Sultr1;2 In Sulfur Sensing, Zheng Zhiliang, Bo Zheng, Thomsa Leustek

Publications and Research

Plants have evolved a sophisticated mechanism to sense the extracellular sulfur (S) status so that sulfate transport and S assimilation/metabolism can be coordinated. Genetic, biochemical, and molecular studies in Arabidopsis over the past 10 years have started to shed some light on the regulatory mechanism of the S response. Key advances in transcriptional regulation (SLIM1, MYB, and miR395), involvement of hormones (auxin, cytokinin, and abscisic acid) and identification of putative sensors (OASTL and SULTR1;2) are highlighted here. Although our current view of S nutrient sensing and signaling remains fragmented, it is anticipated that through further studies a sensing and signaling …

Dbc1/Ccar2 And Ccar1 Are Largely Disordered Proteins That Have Evolved From One Common Ancestor, Jessica Brunquell, Jia Yuan, Aqeela Erwin, Sandy D. Westerheid, Bin Xue

Molecular Biosciences Faculty Publications

Deleted in breast cancer 1 (DBC1, CCAR2, KIAA1967) is a large, predominantly nuclear, multidomain protein that modulates gene expression by inhibiting several epigenetic modifiers, including the deacetylases SIRT1 and HDAC3, and the methyltransferase SUV39H1. DBC1 shares many highly conserved protein domains with its paralog cell cycle and apoptosis regulator 1 (CCAR1, CARP-1). In this study, we examined the full-length sequential and structural properties of DBC1 and CCAR1 from multiple species and correlated these properties with evolution. Our data shows that the conserved domains shared between DBC1 and CCAR1 have similar domain structures, as well as similar patterns of predicted disorder …
