Efficacy Of Deferasirox In Preventing Complications Of Iron Overload In The Iron Overloaded Gerbil, Rabaa M. Al-Rousan

Theses, Dissertations and Capstones

Iron overload is a significant, world-wide problem that results in several chronic diseases including cardiovascular, hepatic and pancreatic complications.The newly developed, orally effective, iron chelating agent deferasirox is thought to offer tremendous promise as an alternative to deferoxamine. However, the efficacy and safety profile of deferasirox is not yet clear. In the present study, the efficacy of deferasirox in removing iron from target tissues has been examined using the gerbil model of iron overload. Deferasirox administration resulted in a significant reduction of iron from cardiac and hepatic tissue. In addition deferasirox reduced iron induced increase in cardiac and hepatic oxidative …

Earthwatch Expedition: Taking Research Experiences To The Classroom, Katherine J. Megivern

Iowa Science Teachers Journal

I participated in the Live from the Field Earthwatch Expedition - Mammals of Nova Scotia, through a fellowship awarded by Wells Fargo. During this experience I participated in research to study the abundance of mammals in Nova Scotia and determine the effect of climate change on natural systems. After this experience I developed an inquiry project for my students in which they study the populations of insects. The students develop their own questions, collect data and make sense of their research. By investigating populations, students are encouraged to see the wonderful biodiversity right in their backyard! This article Promotes National …

Playing The Proof Game: Intelligent Design And The Law, Frank S. Ravitch

Dickinson Law Review (1908-2003)

Intelligent design advocates argue that excluding intelligent design from educational and scientific environments discriminates in favor of methodological naturalism and against other approaches for understanding natural phenomena. These arguments are flawed both legally and philosophically. In order to succeed ID advocates need to demonstrate that ID is science and that public school classes and scientific institutions are public fora for speech. Legal scholarship has generally ignored the most relevant arguments from philosophy of science and the relationship of those arguments to constitutional concepts. This article demonstrates that even when ID is given the benefit of the best scientific, philosophical, and …

Identity And Spirituality: Conventional And Transpersonal Perspectives, Douglas A. Macdonald

International Journal of Transpersonal Studies

Though the relation of spirituality to self has long been recognized in established spiritual

and religious systems, serious scientific interest in spirituality and its relation to identity has

only started to grow in the past 20 years. This paper overviews the literature on spirituality

and identity. Particular attention is given to describing and critiquing conventional and

transpersonal perspectives with emphasis given to empirically testable theories. Using

MacDonald’s (1997, 2000) five dimensional model of spirituality, a structural model of

spirituality is proposed as is a model of spiritual identity formation.

The Rock Art Of The Blood Of The Ancestors Grotto (11sa557): A Natural History Of The Imaging Methodology, Lenville J. Stelle

Anthropology Faculty Scholarship

In the study of rock art in general, and pictographs in particular, how we collect and manipulate the images displayed on a canvas of nature determines both what is seen and what can be reposed for the future. The identification of an undocumented rock art site, primarily pictographic, in the Hill Section of southern Illinois afforded an opportunity to take a fresh look at the methodologies employed in data recovery and analysis. We herein detail a natural history of our investigations of 11SA557. Our methods involved the generation of five different types of image data, an eight-element protocol for the …

Quantum Dot Immuno-Conjugates Allow For Reliable Photo-Stable Detection Of Intracellular Stages Of Toxoplasma Gondii, Natalia Barahona Guerrero

Mahurin Honors College Capstone Experience/Thesis Projects

Luminescent quantum dot nanoparticles have emerged as a highly effective alternative to organic fluorescence probes in a variety of applications employing the use of immunoconjugates. In the present study, we have successfully used quantum dot technology for the immunofluorescent detection of intracellular stages of Toxoplasma gondii in a CV-1 mammalian cell line. This assay will allow us to investigate the question of whether selenium and other antioxidants have a direct impact on the intracellular cycle of the parasite. A Lab-Tek cell culture system was used to determine optimal concentrations of primary and secondary antibodies. Infected CV-1 monolayers were fixed in …

The Influence Of Spatial Scale On Landcover And Avian Community Relationships Within The Upper Green River Watershed, Ky, Cabrina L. Hamilton

Mahurin Honors College Capstone Experience/Thesis Projects

Landscape ecology studies are needed to aid land managers and conservationists in developing management plans that will effectively improve avian population trends. This study uses riparian avian point count survey data and landcover data to examine the possible relationships between riparian avian communities and landcover within the Upper Green River watershed. How avian-landcover relationships change with increasing spatial scale is also examined. Results showed unexpected avian-landcover relationships for specific species. A landcover gradient from open and successional habitat to closed, forest habitat was most prevalent in the study area and explained most of the variation within the avian datasets. Riparian …

Where Do They Go When They Die?, Meridith L. Bartley

Mahurin Honors College Capstone Experience/Thesis Projects

Food webs and matrices are vital to understanding feeding relationships and ecology. Adjacency matrices can be employed to present the direct relationships between predators and prey; these binary matrices utilize 0’s to denote no direct link and 1’s to denote a direct link. We analyzed a variety of published food webs ranging from pine forests in the United States to tussock grasslands in New Zealand. The food webs varied in number of distinguishable taxa present, functional diversity, climates and habitats. Consequently, we expect that our results are not specific to a given system. The published food webs lack flows from …

Modeling Thip;Ate Enzyme Chemistry With Cysteine At A High Ph, Emily Michelle Turner

Mahurin Honors College Capstone Experience/Thesis Projects

Thiolate is a highly reactive species critical to the function of many enzymes. We attempted to model the chemistry of two of these enzymes with cysteine in solution at a high pH. To study cysteine proteases, we increased the pH of a cysteine and 4- nitrophenylacetate solution to create a visible color change when thiolyzed that was monitored through UV-Vis spectroscopy to determine rate constants. To study transferases, we attempted to model two reactions. The first was a methyl transfer from guanine to cysteine which mimicked O6-alkylguanine-DNA alkyltransferase. The second was activation of halogenated hydrocarbons by a mechanism similar to …

Scaling Of Feesing Behavior And Performance In The Goliath Grouper, Epinephelus Itajara, Michelle Riggs

Mahurin Honors College Capstone Experience/Thesis Projects

Scaling is defined as the changes related to body size an animal undergoes during its life history. This change in body size can have implications for habitat use, prey consumed, and predatory threats, among others. The goliath grouper, Epinephelus itajara, undergoes one of the greatest amounts of scaling of any animal known, growing from 3mm at hatching to 2.3 m as adults. This tremendous change has implications for their development and niche as a top-level predator in their habitats. However, the consequences of their drastic change in body size for feeding performance have never been quantified. Here, a juvenile goliath …

Streaming Fish Sampling: Abundance Versus Biomass Measurements And Determining A Minimum Number Of Years To Sample, Sarah B. Vied

Mahurin Honors College Capstone Experience/Thesis Projects

Abundance and biomass are commonly used for estimating stream fish assemblage and community structure, yet questions arise whether one measurement contains more information about an assemblage and how long sampling should be. Principal component loadings derived from fish biomass measurements taken from Buck Creek in Allen County Kentucky were statistically compared to corresponding measures of abundance to test for significant differences in the two data sets. A sliding window analysis based on abundance was used to determine the minimum number of years a stream should be sampled. Abundance and biomass were not found to be significantly different; correlations of the …

The Impacts Of Global Warming On Appalachian Wildflower Phenologies, Rachel D. Wigginton

Mahurin Honors College Capstone Experience/Thesis Projects

Public and private interest in global warming has prompted exploration of the impacts this phenomenon may impart on ecosystem functions. Flowering phenology has been one of the areas many scientists believe is particularly susceptible to the impacts of anthropogenic warming. Over three weekends in spring of 2008, the vernal herb community was surveyed at five sites within the Great Smoky Mountains regions of the southern Appalachian Mountains. The intent was to capture the naturally occurring elevational gradient and determine if the temperature cue for blooming was the same for all co-flowering species in the study. This information would allow for …

Sythesis Of Carporide Derivatives For Sodium-Proton Exchange Inhibition, Jacob Adam Vervynckt

Mahurin Honors College Capstone Experience/Thesis Projects

Over 200,000 people in the United States are diagnosed annually with malignant brain tumors. Current therapeutic methods prove ineffective at treating this type of cancer due to the inability to selectively target cancer cells. Research has shown that brain cancer cells are heavily dependent on the sodium-proton exchanger (NHE) and sodium-calcium exchanger (NCX) due to their increased metabolic activity. Inhibiting these proteins disrupts pH and ion balances within cancer cells while leaving healthy cells unaffected, leading to selective glial cell death. Therefore, NHE and NCX inhibition allow for selective targeting of brain cancer cells. The challenge that remains in using …

Solar And Topographical Breeding Habitat Preferences Of Two Damselflies Calopteryx Aequabilis And Calopteryx Maculata, Christopher St. Andre

Undergraduate Review

As the global climate changes many species are forced to adapt, but if the climate changes beyond their tolerance levels they can face extinction1. Scientists need to work fast in order to mitigate these extinctions. Using field observations of species’ habitats coupled with the use of geographic information systems (GIS), researchers can model the locations of ideal habitats. Using these models, scientists can work to improve conservation efforts by raising the populations of dwindling species or predicting locations to place new subpopulations. Data used in GIS are spatially explicit, so stored within individual data sets and information systems are locational …

A Theoretical Framework To Guide The Re-Engineering Of Technology Education, Todd R. Kelley, Nadia Kellam

Publications

Before leaders in technology education are able to identify a theoretical framework upon which a curriculum is to stand, they must first grapple with two opposing views of the purpose of technology education – education for all learners or career/technical education. Dakers (2006) identifies two opposing philosophies that can serve as a framework for technology education, both inspired by ancient Greece, with the works of Descartes and the birth of positivism. Later reappearing in Pascal’s writings of the mathematical mind, and finally with Rousseau in the mid 1700s, the theoretical arguments of academic verses vocational were established in education, and …

Evolution Of Gene Structure In Multicellular Eukaryotes, Maria Hester

Inquiry: The University of Arkansas Undergraduate Research Journal

We investigated the patterns of intron conservation in eukaryotes for five different genes. The genes examined were ribosomal proteins L8, S14 and S17, along with elongation factor 2B and triose phosphate isomerase. Intron conservation for S14, S17, and triose phosphate isomerase was determined for 32 species representing the major branches of multicellular eukaryotes. For 25 conserved introns 16 were phase 0, five were phase 1, and four were phase 2. Triose phosphate isomerase had five of nine conserved introns shared between plants and animals, where S14 had one of nine and S17 had one of seven. However, there were two …

Carbon Nanotube Cluster Based Micro-Fluidic System For Bacteria Capture, Concentration, And Separation, Chris Nelson

Inquiry: The University of Arkansas Undergraduate Research Journal

Disease-causing pathogens continue presenting enormous global health problems, especially due to their easy transmittance to people via water supply systems. The detection, filtration, and purification of bacteria-contaminated water samples are complex activities, ones subject to considerable error. Here we present a new and highly effective micro-fluidic system with carbon nanotube (CNT) clusters for effective and efficient detection, filtration, and purification of bacteria-contaminated medium. The developed system is based upon two unique properties of CNT clusters: high bacterial affinity and magnetic susceptibility. The CNTs 'high affinity to bacteria cells makes them a key candidate for the bacteria adsorption. The magnetic susceptibility …

Fatigue And Its Effect On Cabin Crew Member Performance, Stephanie Hide Mas

International Symposium on Aviation Psychology - 2009

Since 1993, the National Transportation Safety Board (NTSB) has stated fatigue was a contributing factor in eight airline catastrophes in the US resulting in 250 fatalities. Many proposals to mitigate fatigue as a safety issue in aviation have been suggested. Those on the NTSB List of Most Wanted Transportation Safety Improvements involve “hours of on-duty work” rules, which provide an essential set of limits on the work day for all transportation workers. However, most fatigue studies have focused on cockpit crew and not on the cabin crew. This report investigates cabin crew members, their scheduled work, rest and sleep times …
