Differential Activation Of Frontoparietal Attention Networks By Social And Symbolic Spatial Cues, Andrew D. Engell, Lauri Nummenmaa, Nikolaas N. Oosterhof, Richard N. Henson, James V. Haxby, Andrew J. Calder

Dartmouth Scholarship

Perception of both gaze-direction and symbolic directional cues (e.g. arrows) orient an observer’s attention toward the indicated location. It is unclear, however, whether these similar behavioral effects are examples of the same attentional phenomenon and, therefore, subserved by the same neural substrate. It has been proposed that gaze, given its evolutionary significance, constitutes a ‘special’ category of spatial cue. As such, it is predicted that the neural systems supporting spatial reorienting will be different for gaze than for non-biological symbols. We tested this prediction using functional magnetic resonance imaging to measure the brain’s response during target localization in which laterally …

Metal-Organic Materials: From Design Principles To Practical Applications, Mohamed H. Alkordi

USF Tampa Graduate Theses and Dissertations

The works presented herein outline rational design approaches towards construction of solid state materials with great potentials to answer some of current demanding applications. Specifically, the materials targeted are metal−organic materials with desirable structural features and functional properties. Metal−organic materials are constructed from organic linker molecules and metal ions under relatively mild solvothermal reaction conditions that preserve the structural features of the relatively simple building blocks. Therefore, it is feasible to conceive a retrospective pathway of the reaction and thus deconstruct the desirable structures into simple, chemicallyrelevant, building blocks in an approach known as the molecular building block approach. Due …

Inhibition Of Host Vacuolar H+-Atpase Activity By A Legionella Pneumophila Effector., Li Xu, Xihui Shen, Andrew Bryan, Simran Banga, Michele S. Swanson, Zhao-Qing Luo

Department of Biological Sciences Faculty Publications

Legionella pneumophila is an intracellular pathogen responsible for Legionnaires' disease. This bacterium uses the Dot/Icm type IV secretion system to inject a large number of bacterial proteins into host cells to facilitate the biogenesis of a phagosome permissive for its intracellular growth. Like many highly adapted intravacuolar pathogens, L. pneumophila is able to maintain a neutral pH in the lumen of its phagosome, particularly in the early phase of infection. However, in all cases, the molecular mechanisms underlying this observation remain unknown. In this report, we describe the identification and characterization of a Legionella protein termed SidK that specifically targets …

The Yellowstone caldera contains the most numerous and diverse geothermal systems on Earth, yielding an extensive array of unique high-temperature environments that host a variety of deeply-rooted and understudied Archaea, Bacteria and Eukarya. The combination of extreme temperature and chemical conditions encountered in geothermal environments often results in considerably less microbial diversity than other terrestrial habitats and offers a tremendous opportunity for studying the structure and function of indigenous microbial communities and for establishing linkages between putative metabolisms and element cycling. Metagenome sequence (14-15,000 Sanger reads per site) was obtained for five hightemperature (>65°C) chemotrophic microbial communities sampled from …

Rss Feeds Freed From Readers: Getting The Benefits Without Training The Users, Greg R. Argo

Library Technology Conference

RSS Feed technology, so promising to information professionals right out of the gate, proved to be difficult to harness and focus for a number of reasons, including the need to train users how to use RSS, the need for users to maintain a separate RSS reader, and constraints on users’ time and attention. After training sessions, users unanimously saw its potential, but most didn’t keep up with the technology’s demands. Over the last few years, “big gun” library vendors like EBSCO, ProQuest, and Gale have started including functionality that allows users to generate RSS feeds for their searches. At the …

Optimizing Vaccine Allocation At Different Points In Time During An Epidemic, Laura Matrajt, Ira M. Longini Jr.

UW Biostatistics Working Paper Series

For current pandemic influenza H1N1, vaccine production started in the early summer, and vaccination started in the fall. In most countries, by the time vaccination started, the second wave of H1N1 was already under way. With limited supplies of vaccine, it might be a good strategy to vaccinate the high-transmission groups earlier in the epidemic, but it might be a better use of resources to protect instead the high-risk groups later on. We develop a deterministic epidemic model with two age-groups (children and adults) and further subdivide each age group in low and high risk. We compare optimal vaccination strategies …

Immunosuppressive Effects Of Triclosan, Nonylphenol, And Ddt On Human Natural Killer Cells In Vitro, Felicia Udoji, Tamara Martin, Rachel Etherton, Margaret M. Whalen

Chemistry Faculty Research

Human natural killer (NK) cells are a first-line immune defense against tumor cells and virally-infected cells. If their function is impaired, it leaves an individual more susceptible to cancer development or viral infection. The ability of compounds that contaminate the environment to suppress the function of NK cells could contribute to the increased risk of cancer development. There are a wide spectrum of compounds that significantly contaminate water and food that are consumed by humans, leading to accumulation of some of these compounds in human tissues. In the current study, we examined the ability of three such compounds to diminish …

Tredd—A Database For Tandem Repeats Over The Edit Distance, Dina Sokol, Firat Atagun

Publications and Research

A ‘tandem repeat’ in DNA is a sequence of two or more contiguous, approximate copies of a pattern of nucleotides. Tandem repeats are common in the genomes of both eukaryotic and prokaryotic organisms. They are significant markers for human identity testing, disease diagnosis, sequence homology and population studies. In this article, we describe a new database, TRedD, which contains the tandem repeats found in the human genome. The database is publicly available online, and the software for locating the repeats is also freely available. The definition of tandem repeats used by TRedD is a new and innovative definition based upon …

Effects Of Uvb-Induced Oxidative Stress On Protein Expression And Specific Protein Oxidation In Normal Human Epithelial Keratinocytes: A Proteomic Approach, Marzia Perluigi, Fabio Di Domenico, Carla Blarzino, Cesira Foppoli, Chiara Cini, Alessandra Giorgi, Caterina Grillo, Federico De Marco, D. Allan Butterfield, Maria E. Schininà, Raffaella Coccia

Chemistry Faculty Publications

BACKGROUND: The UVB component of solar ultraviolet irradiation is one of the major risk factors for the development of skin cancer in humans. UVB exposure elicits an increased generation of reactive oxygen species (ROS), which are responsible for oxidative damage to proteins, DNA, RNA and lipids. In order to examine the biological impact of UVB irradiation on skin cells, we used a parallel proteomics approach to analyze the protein expression profile and to identify oxidatively modified proteins in normal human epithelial keratinocytes.

RESULTS: The expression levels of fifteen proteins - involved in maintaining the cytoskeleton integrity, removal of damaged proteins …

Neuroscience Faculty Publications

BACKGROUND: Neurotrophic factors, such as glial cell line-derived neurotrophic factor (GDNF), have shown great promise for protection and restoration of damaged or dying dopamine neurons in animal models and in some Parkinson's disease (PD) clinical trials. However, the delivery of neurotrophic factors to the brain is difficult due to their large size and poor bio-distribution. In addition, developing more efficacious trophic factors is hampered by the difficulty of synthesis and structural modification. Small molecules with neurotrophic actions that are easy to synthesize and modify to improve bioavailability are needed.

METHODS AND FINDINGS: Here we present the neurobiological actions of dopamine …

Influences On Active Family Leisure And Its Relationship To Obesity, Shallie Marlene Taylor

Theses and Dissertations

The purpose of this study was to examine how attitude, subjective norm, and perceived behavioral control influence adolescents' intent to participate in active family leisure and furthermore to explore the nature of the relationship between active family leisure and body mass index (BMI) among adolescents. Adolescents (N = 472) completed an online questionnaire assessing the theory of planned behavior (TPB) variables, active family leisure, individual active leisure, and BMI. Structural equation modeling was used to analyze the data. Tests of direct paths of attitude, subjective norm, and perceived behavioral control to intent indicated these variables were significant predictors of intent …

The Effects Of Video Self-Modeling On Elementary Students' On-Task Behavior As A Response To Intervention, Anika Kronmiller Bales

Theses and Dissertations

Effective interventions are imperative for students who are at-risk for academic failure. Response to Intervention (RTI), a service delivery framework, is gaining momentum in schools as it aims to provide effective and appropriate interventions of varying degrees. Frequently used in the form of a three-tier process, RTI addresses academic and behavioral deficits for students first at a school-wide level; next, at an individualized level; and finally, at a more intense individualized level. This study examined the effects of video self-modeling (VSM) as a Tier 2 RTI for two students in general education classrooms. Both students exhibited low rates of on-task …

Syngas Fermentation: Quantification Of Assay Techniques, Reaction Kinetics, And Pressure Dependencies Of The Clostridial P11 Hydrogenase, Bradley E. Skidmore

Theses and Dissertations

Ethanol usage as a transportation fuel is rapidly increasing in the United States. Production of ethanol from cellulose feedstocks via gasification followed by syngas fermentation offers an environmentally friendly approach that mitigates many of the adverse effects associated with production from corn. In the syngas fermentation process, the hydrogenase enzyme of the fermentation bacterium, Clostridium P11 for this work, supplies electrons to the metabolic pathway, facilitating ethanol production. In this thesis, an assay for P11 hydrogenase activity was developed. It was determined that 1) less than 4 minutes of sparging with 50 sccm H2 is needed to reduce O2 levels …

Adventures In Nontranslational Research, Martin Chalfie

IMSA Great Minds Program ®

Over the last ten years administrators, governmental officials, and clinical researchers have increasingly called for a greater emphasis on "translational research", i.e., research that translates findings in the laboratory into new treatments for medical conditions, over basic research in the biological sciences. Although the application of biological research to human disease (as well as toward improvements in agriculture and development of biotechnology) is important, I feel that an increased emphasis is not needed and is actually detrimental. Ultimately, this emphasis is self-defeating because one needs the fruits of basic research to fuel these applications. I will give examples from my …

Turning Points: Stories Of How Students Get Beyond Antipathy Toward An Academic Course, Cheryl Lynn Morse

Theses and Dissertations

The purpose of this qualitative study was to examine the narratives of 10 students who began an academic course with strong negative attitudes but finished the course with strong positive attitudes. In the beginning of the course, each student exhibited one of these three tendencies: apathetic, compliant, or disillusioned; however, by the end of the course, they exhibited a transformed disposition. This study attempts to answer the question of what the turning points were for their transformation and how they made the change. The findings of this study were that regardless of individual tendencies, the ability to exercise agency was …
