Energetic Costs Of Thermoregulation And Population Life-History Characterization In Eastern Collared Lizards, Casey Lee Brewster Jul 2012

Energetic Costs Of Thermoregulation And Population Life-History Characterization In Eastern Collared Lizards, Casey Lee Brewster

Theses and Dissertations

Thermoregulation theory makes distinct predictions as to the optimal level of thermoregulation when the costs associated with the thermal habitat are less favorable. I designed a manipulative experiment to test the hypothesis that thermal constraints reduce growth rates in hatchling-collared lizards by imposing high and low cost thermoregulation treatments. Lizards thermoregulated similarly between treatments, but grew more slowly in the high cost thermoregulation treatment. My results suggest that the decrement to growth in the high cost treatment is primarily the result of energy diverted from growth to locomotion shuttling between suitable micro- habitats. I combined this experiment with a field …

Writing Across The Curriculum: A Study Of Possibilities For Ualr, Mia Phillips Jul 2012

Writing Across The Curriculum: A Study Of Possibilities For Ualr, Mia Phillips

Theses and Dissertations

This study seeks to determine the feasibility of implementing writing across the curriculum (WAC) at UALR. For the purposes of this study, WAC will be defined as a methodology of instruction for undergraduate students attending a college or university that emphasizes writing in any discipline or major offered at that university. In other words, writing assignments and activities occur in classes that typically do not focus on writing like English and writing courses typically do. By utilizing a survey of best practices at four other universities, as well as a survey of attitudes of UALR faculty, this paper will provide …

Validation Of Interaction Between The Glyt2 And The Nsf, David Quispe Escudero, Hector Cuevas, Luciana Girotto Gentil, Manuel Miranda Jul 2012

Validation Of Interaction Between The Glyt2 And The Nsf, David Quispe Escudero, Hector Cuevas, Luciana Girotto Gentil, Manuel Miranda

COURI Symposium Abstracts, Summer 2012

The Glycine Transporter 2 (GlyT2) is a presynaptic membrane transporter in charge of re-uptake of glycine from the synaptic cleft back into the presynaptic neuron. GlyT2 is present only in vertebrate neurons and possesses a 200 amino- acid long N-terminal tail of unknown function. We hypothesize that such domain serve as a docking site for a network of presynaptic proteins, such as NSF that plays a pivotal role during vesicle transport. Therefore, our goal in this project is to analyze protein-protein interaction between GlyT2 and NSF. We have used co-immunoprecipitation experiments from rat brainstem with GlyT2 and NSF antibodies as …

Evolution Of Growth Habit, Inflorescence Architecture, Flower Size, And Fruit Type In Rubiaceae: Its Ecological And Evolutionary Implications, Sylvain G. Razafimandimbison, Stefan Ekman, Timothy D. Mcdowell, Birgitta Bremer Jul 2012

Evolution Of Growth Habit, Inflorescence Architecture, Flower Size, And Fruit Type In Rubiaceae: Its Ecological And Evolutionary Implications, Sylvain G. Razafimandimbison, Stefan Ekman, Timothy D. Mcdowell, Birgitta Bremer

ETSU Faculty Works

During angiosperm evolution, innovations in vegetative and reproductive organs have resulted in tremendous morphological diversity, which has played a crucial role in the ecological success of flowering plants. Morindeae (Rubiaceae) display considerable diversity in growth form, inflorescence architecture, flower size, and fruit type. Lianescent habit, head inflorescence, small flower, and multiple fruit are the predominant states, but arborescent habit, non-headed inflorescence, large flower, and simple fruit states occur in various genera. This makes Morindeae an ideal model for exploring the evolutionary appearances and transitions between the states of these characters. We reconstructed ancestral states for these four traits using a …

Canopy Effects On Tropical Leaf Litter Arthropods, Theodore Peter Sumnicht Jul 2012

Canopy Effects On Tropical Leaf Litter Arthropods, Theodore Peter Sumnicht

Theses and Dissertations

Changes in canopy structure, which are likely to occur at faster rates due to climate change, affect leaf litter structure and the ecology of litter-dwelling organisms. One such change is the increased abundance of lianas in tropical forest canopies. Here, I quantify effects of these changes on tropical leaf litter arthropod communities by surveying patches of Panamanian forest where lianas have been removed, and experimentally isolating two aspects of the litter environment affected by canopy structure: incident light and litter depth. Increased litter produced by liana cutting resulted in increases in ant species richness and arthropod abundance. Structural complexity was …

Canopy Ants Of Central Arkansas And The Atlantic Forest Of Brazil: Community Patterns, Petrus Fauaze Moreira Jul 2012

Canopy Ants Of Central Arkansas And The Atlantic Forest Of Brazil: Community Patterns, Petrus Fauaze Moreira

Theses and Dissertations

Ants in the forest canopy are of special ecological interest due to their high diversity and ecological importance in this relatively inaccessible system. I explored the ecology of ants of temperate and tropical arboreal settings in Central Arkansas and Brazil respectively. I tested the hypothesis that biotic (e.g., tree identity) and abiotic (e.g., spatial distribution) factors regulate the diversity and composition of ants in the forest canopy, as well as the potential conservation benefits of agroforests in the tropics. In Arkansas, tree identity influenced ant species richness in tree crowns, in Brazil, ant species richness was significantly different between primary …

My Sister, Our Stories: Exploring The Lived Experience Of School Leavers Through Narrative And Poetics, C. Amelia Davis, Jennifer L. Pepperell Jul 2012

My Sister, Our Stories: Exploring The Lived Experience Of School Leavers Through Narrative And Poetics, C. Amelia Davis, Jennifer L. Pepperell

The Qualitative Report

The purpose of this study was to explore the educational experiences of two adult female siblings who are both school leavers. Through the use of thematic narrative analysis, sibling narratives and poetic re-presentations, their stories were developed. These stories represent the participants’ experiences of prior schooling and their current commitments to education. While each story conveyed a profound similarity in terms of prior schooling, contrasting narratives were illustrated through description of transitional moments and sibling relationship. The analysis also explored the intersections of race, gender, and social class within educative moments of the life experiences of the participants.

Measuring And Comparing Brain Cortical Surface Area And Other Areal Quantities, Anderson M. Winkler, Mert R. Sabuncu, B T. Yeo, Bruce Fischl, Douglas N. Greve, Peter Kochunov, Thomas E. Nichols, John Blangero, David C. Glahn Jul 2012

Measuring And Comparing Brain Cortical Surface Area And Other Areal Quantities, Anderson M. Winkler, Mert R. Sabuncu, B T. Yeo, Bruce Fischl, Douglas N. Greve, Peter Kochunov, Thomas E. Nichols, John Blangero, David C. Glahn

School of Medicine Publications

Structural analysis of MRI data on the cortical surface usually focuses on cortical thickness. Cortical surface area, when considered, has been measured only over gross regions or approached indirectly via comparisons with a standard brain. Here we demonstrate that direct measurement and comparison of the surface area of the cerebral cortex at a fine scale is possible using mass conservative interpolation methods. We present a framework for analyses of the cortical surface area, as well as for any other measurement distributed across the cortex that is areal by nature. The method consists of the construction of a mesh representation of …

Spontaneous Spheroid Budding From Monolayers: A Potential Contribution To Ovarian Cancer Dissemination, Jillian C. Pease, Molly Brewer, Jennifer S. Tirnauer Jul 2012

Spontaneous Spheroid Budding From Monolayers: A Potential Contribution To Ovarian Cancer Dissemination, Jillian C. Pease, Molly Brewer, Jennifer S. Tirnauer

UCHC Articles - Research

Ovarian cancer is the most lethal gynaecologic cancer, in large part because of its early dissemination and rapid development of chemotherapy resistance. Spheroids are clusters of tumor cells found in the peritoneal fluid of patients that are thought to promote this dissemination. Current models suggest that spheroids form by aggregation of single tumor cells shed from the primary tumor. Here, we demonstrate that spheroids can also form by budding directly as adherent clusters from a monolayer. Formation of budded spheroids correlated with expression of vimentin and lack of cortical E-cadherin. We also found that compared to cells grown in monolayers, …

How Dtra/Scc-Wmd Is Minimizing The Risk Of Catastrophic Accidents, Anne Marek Jul 2012

How Dtra/Scc-Wmd Is Minimizing The Risk Of Catastrophic Accidents, Anne Marek

The Journal of Conventional Weapons Destruction

The U.S. Defense Threat Reduction Agency and the U.S. Strategic Command Center for Combating Weapons of Mass Destruction are taking measures to reduce the number of accidents caused by conventional weapons. More accidents are occurring with the proliferation of small arms and light weapons; DTRA wants to significantly reduce those accidents and the risks of their occurrence. In doing so, DTRA's SA/LW Program organizes and conducts seminars on the practices for physical security and stockpile management throughout the world. Its goal is to educate countries through seminars on proper management of stockpiles and to ultimately assuage the risk of those …

Vaske, Kimberly N. White, Tanya L. Cohen, Helene C. Vervoort, Karen Tenney, Frederick A. Valeriote, Leonard F. Bjeldanes, Phillip Crews

Natural Sciences and Mathematics | Faculty Scholarship

A nuclear factor-κB (NF-κB) luciferase assay has been employed to identify the bengamides, previously known for their anti-tumor activity, as a new class of immune modulators. A unique element of this study was that the bengamide analogs were isolated from two disparate sources, Myxococcus virescens (bacterium) and Jaspis coriacea (sponge). Comparative LC-MS/ELSD and NMR analysis facilitated the isolation of M. viriscens derived samples of bengamide E (8) and two congeners, bengamide E' (13) and F' (14) each isolated as an insperable mixture of diastereomers. Additional compounds drawn from the UC, Santa Cruz repository allowed expansion of the structure activity relationship …

Electrical and Computer Engineering Faculty Publications and Presentations

Airborne particulate matter has been shown to be associated with morbidity and mortality, and may interfere with certain sensitive experiment. Understanding the levels and movements of particulate matter in an enclosed space can lead to a reduction in the impact of this material on health and experimental results. A system of environmental sensors including particulate matter, selected gasses, humidity, temperature, and pressure can be used to assist in tracking air movement, providing real-time mapping of potential contaminants as they move through a space. In this paper we present a system that is capable of sensing these environmental factors, collecting data …

Teachers' Perceptions Of Rural Stem Teaching: Implications For Rural Teacher Retention, Kasey P. S. Goodpaster, Omolola A. Adedokun, Gabriela C. Weaver Jul 2012

Teachers' Perceptions Of Rural Stem Teaching: Implications For Rural Teacher Retention, Kasey P. S. Goodpaster, Omolola A. Adedokun, Gabriela C. Weaver

The Rural Educator

Rural school districts often struggle with attracting and retaining high-quality teachers, especially in science subject areas. However, little is known about STEM in-service teachers’ lived experiences of rural teaching as they relate to retention. In this phenomenographical study, six rural in-service science teachers were interviewed regarding their perceptions of the benefits and challenges of teaching in rural schools in general, and teaching science subjects in particular. Community interactions, professional development, and rural school structures emerged as three key factors related to rural teacher retention. Participants viewed each of these factors as having both positive and negative aspects. Findings from this …

Tfiiic Localizes Budding Yeast Etc Sites To The Nuclear Periphery, Shin Ichiro Hiraga, Sotirios Botsios, David Donze, Anne D. Donaldson

Faculty Publications

Chromatin function requires specific three-dimensional architectures of chromosomes. We investigated whether Saccharomyces cerevisiae extra TFIIIC (ETC) sites, which bind the TFIIIC transcription factor but do not recruit RNA polymerase III, show specific intranuclear positioning. We show that six of the eight known S. cerevisiae ETC sites localize predominantly at the nuclear periphery, and that ETC sites retain their tethering function when moved to a new chromosomal location. Several lines of evidence indicate that TFIIIC is central to the ETC peripheral localization mechanism. Mutating or deleting the TFIIIC-binding consensus ablated ETC -site peripheral positioning, and inducing degradation of the TFIIIC subunit …

Spectroelectrochemical Elucidation Of The Kinetics Of Two Closely Spaced Electron Transfers, Robert L. Keesey, Michael D. Ryan Jul 2012

Spectroelectrochemical Elucidation Of The Kinetics Of Two Closely Spaced Electron Transfers, Robert L. Keesey, Michael D. Ryan

Chemistry Faculty Research and Publications

The use of spectroelectrochemistry to facilitate the analysis of an EE mechanism was reported in this work. Using a set of spectra as a function of potential, the spectra of all three oxidation states were determined using evolving window factor analysis. From these spectra, the concentration of each species in solution was determined for each potential. Using these data, the current was calculated. Unlike the direct measurement of current, the current due to each redox process was determined, allowing one to analyze each redox process separate from the other. With the use of the Butler–Volmer equation, the redox potential and …

Nitrated Fibrinogen Is A Biomarker Of Oxidative Stress In Venous Thromboembolism, Marissa Martinez, Adam Cuker, Angela Mills, Richard Lightfoot, Yiying Fan, W.H. Wilson Tang, Stanley L. Hazen, Harry Ischiropoulos Jul 2012

Nitrated Fibrinogen Is A Biomarker Of Oxidative Stress In Venous Thromboembolism, Marissa Martinez, Adam Cuker, Angela Mills, Richard Lightfoot, Yiying Fan, W.H. Wilson Tang, Stanley L. Hazen, Harry Ischiropoulos

Mathematics and Statistics Faculty Publications

The pathogenesis of venous thromboembolism (VTE) is linked to inflammation and oxidant production, although specific markers for these pathways with pathological relevance to VTE have not been explored. The coagulant protein fibrinogen is posttranslationally modified by nitric oxide-derived oxidants to nitrated fibrinogen in both acute and chronic inflammatory states. Therefore, nitrated fibrinogen may serve as a marker of inflammation and oxidative stress in VTE. To test this hypothesis we enrolled subjects (n=251) presenting with suspected VTE at the University of Pennsylvania Hospital emergency department, 50 (19.9%) of whom were positive by imaging or 90-day follow-up. Mean nitrated fibrinogen was elevated …

Immunotherapy For B-Cell Neoplasms Using T Cells Expressing Chimeric Antigen Receptors : From Antigen Choice To Clinical Implementation, Mohamed-Rachid Boulassel, Ahmed Galal Jul 2012

Immunotherapy For B-Cell Neoplasms Using T Cells Expressing Chimeric Antigen Receptors : From Antigen Choice To Clinical Implementation, Mohamed-Rachid Boulassel, Ahmed Galal

Sultan Qaboos University Medical Journal

Immunotherapy with T cells expressing chimeric antigen receptors (CAR) is being evaluated as a potential treatment for B-cell neoplasms. In recent clinical trials it has shown promising results. As the number of potential candidate antigens expands, the choice of suitable target antigens becomes more challenging to design studies and to assess optimal efficacy of CAR. Careful evaluation of candidate target antigens is required to ensure that T cells expressing CAR will preferentially kill malignant cells with a minimal toxicity against normal tissues. B cells express specific surface antigens that can theoretically act as targets for CAR design. Although many of …

Understanding Dyslexia In Children Through Human Development Theories, Thuraya A. Al-Shidhani, Vinita Arora Jul 2012

Understanding Dyslexia In Children Through Human Development Theories, Thuraya A. Al-Shidhani, Vinita Arora

Sultan Qaboos University Medical Journal

Dyslexia is a specific learning disability that is neurological in origin, with an estimated overall worldwide prevalence of 5–10% of the population. It is characterised by difficulties in reading, accuracy, fluency, spelling and decoding abilities. The majority of publications reviewed indicated that screening is performed at the preschool level. Screening can also be conducted at birth or the first year of life. Understanding human development theory, for example, Piaget’s human development theory, may help determine at which stage of childhood development dyslexia is more detectable, and therefore guide the management of this disability. The objective of this review is to …
