Acute Putrescine Supplementation With Schwann Cell Implantation Improves Sensory And Serotonergic Axon Growth And Functional Recovery In Spinal Cord Injured Rats, J. Bryan Iorgulescu, Samik P. Patel, Jack Louro, Christian M. Andrade, Andre R. Sanchez, Damien D. Pearse

Internal Medicine Faculty Publications

Schwann cell (SC) transplantation exhibits significant potential for spinal cord injury (SCI) repair and its use as a therapeutic modality has now progressed to clinical trials for subacute and chronic human SCI. Although SC implants provide a receptive environment for axonal regrowth and support functional recovery in a number of experimental SCI models, axonal regeneration is largely limited to local systems and the behavioral improvements are modest without additional combinatory approaches. In the current study we investigated whether the concurrent delivery of the polyamine putrescine, started either 30 min or 1 week after SCI, could enhance the efficacy of SCs …

A Black Deer At Black Cave: New Pictograph Radiocarbon Date For The Lower Pecos, Texas, Lennon Bates, Amanda Castañeda, Carolyn Boyd, Karen Steelman

KIP Articles

A Pecos River style painting of a black deer from Black Cave Annex (41VV76a) in southwest Texas was radiocarbon dated. Using plasma oxidation and accelerator mass spectrometry, we obtained an age of 1465 ± 40 RCYBP (2 sigma calibrated age range of A.D. 470-660). This age is younger than the accepted age range for Pecos River style paintings, which is approximately 4000-3000 years B.P. This new measurement in association with other younger dates prompts us to question whether the Pecos River style endured for a longer time period than previously thought. More radiocarbon research is needed in order to understand …

Crevice Interments Deconstructed, Stephen L. Black, M. Katherine Spradley, Michelle D. Hamilton

KIP Articles

The discovery of two well-preserved human crania in a crevice overlooking a spring-fed creek near Austin, Texas, led to medico-legal, archeological, and bioanthropological investigations aimed at understanding the context and biological affinity of the crania. Archeological excavations uncovered no evidence that the crania were interred in the crevice during prehistoric times. Skeletal analysis showed they were of Native American ancestry. Radiocarbon dating indicated they are contemporary to one another and probably date to the seventh or eighth century A.D. Measured stable isotopic rations of carbon (13C/12C) and nitrogen (15N/14N) derived from human bone collagen samples from the crania are not …

"A Happier Way Of Learning" : The Visual Instruction Movement, 1918-1928, Wendell G. Johnson

Graduate Research Theses & Dissertations

The Visual Instruction Movement (1918-1928) was a constituent part of the field of visual education, which began in the early 1900s. With the further development of sound films and radio, it became audiovisual education; by the 1950s the field was known as educational technology. The Visual Instruction Movement experienced extensive growth during the decade 1918-1928. According to Paul Saettler, several key characteristics of contemporary educational technology arose during the Visual Instruction Movement (1918-1928): professional journals and organizations, research studies, formal courses in visual education, and visual education departments and extension services. In addition to Saettler's list of developments in educational …

The Cavernicolous Oniscidea (Crustacea: Isopoda) Of Portugal. European Journal Of Taxonomy, Ana Sofia P.S. Reboleira, Gonçalves Fernando, Pedro Oromí

KIP Articles

The study of subterranean Oniscidea in Portugal has been neglected for nearly 70 years, but recent investigations have revealed high diversity. All the terrestrial isopods from caves of mainland Portugal, including data from the literature and new material, are listed, revealing new biodiversity patterns. Twenty-seven species, belonging to 15 genera and six families, are known, of which 16 species are considered to be exclusively from subterranean ecosystems, i.e., troglobionts. Trichoniscidae is the most diverse family. Seven species in the family Trichoniscidae and one species in the family Styloniscidae are described as new (all with Reboleira & Taiti as authors): Trichoniscoides …

Cave Diplopoda Of Southern China With Reference To Millipede Diversity In Southeast Asia, Sergei I. Golovatch

KIP Articles

The diversity of Diplopoda in caves of southern China is remarkably high, often 5–6 species per cave, consisting mostly of local endemics and presumed troglobionts. These are evidently biased to just a few lineages, mainly members of the orders Chordeumatida and Callipodida, the families Cambalopsidae (Spirostreptida) and Haplodesmidae (Polydesmida) or the genera Pacidesmus, Epanerchodus and Glenniea (all Polydesmida, Polydesmidae), Trichopeltis (Polydesmida, Cryptodesmidae), Dexmoxytes (Polydesmida, Paradoxosomatidae) and Hyleoglomeris (Glomerida, Glomeridae). All these taxa, especially the Paradoxosomatidae and Cambalopsidae (usually amounting to about 60% and 10% of the total species diversity in the Oriental fauna, respectively), are moderately to highly speciose across …

Sex And Hibernaculum Temperature Predict Survivorship In White-Nose Syndrome Affected Little Brown Myotis (Myotis Lucifugus), Laura E. Grieneisen, Sarah A. Brownlee-Bouboulis, Joseph S. Johnson

KIP Articles

White-nose syndrome (WNS), an emerging infectious disease caused by the novel fungus Pseudogymnoascus destructans, has devastated North American bat populations since its discovery in 2006. The little brown myotis, Myotis lucifugus, has been especially affected. The goal of this 2-year captive study was to determine the impact of hibernacula temperature and sex on WNS survivorship in little brown myotis that displayed visible fungal infection when collected from affected hibernacula. In study 1, we found that WNS-affected male bats had increased survival over females and that bats housed at a colder temperature survived longer than those housed at warmer temperatures. In …

Range-Wide Genetic Analysis Of Little Brown Bat (Myotis Lucifugus) Populations: Estimating The Risk Of Spread Of White-Nose Syndrome, Maarten J. Vonhof, Amy L. Russell, Cassandra M. Miller-Butterworth

KIP Articles

The little brown bat (Myotis lucifugus) is one of the most widespread bat species in North America and is experiencing severe population declines because of an emerging fungal disease, white-nose syndrome (WNS). To manage and conserve this species effectively it is important to understand patterns of gene flow and population connectivity to identify possible barriers to disease transmission. However, little is known about the population genetic structure of little brown bats, and to date, no studies have investigated population structure across their entire range. We examined mitochondrial DNA and nuclear microsatellites in 637 little brown bats (including all currently recognized …

Addition Of Interleukin-21 For Expansion Of T-Cells For Adoptive Immunotherapy Of Murine Melanoma, Christine Kathryn Zoon, Wen Wan, Laura Graham, Harry D. Bear

Surgery Publications

We previously demonstrated that interleukin (IL)-7/15 was superior to IL-2 for expansion of T cells in vitrofor adoptive immunotherapy. We sought to ascertain whether IL-21 would further improve yield and therapeutic efficacy of T cells in culture. Naïve T cell receptor (TcR) transgenic splenocytes or antigen-sensitized lymph node cells were harvested from PMEL-1 mice and exposed to bryostatin-1 and ionomycin (B/I) for 18 h. Cells were then cultured in IL-2, IL-21, IL-7/15 or IL-7/15/21 for six days. Harvested cells were analyzed by flow cytometry and used to treat C57Bl/6 mice injected intravenously with B16 melanoma. Lungs were harvested and …

Ingroup Bias And Ingroup Projection In The Furry Fandom, Stephen Reysen, Courtney N. Plante, Sharon E. Roberts, Kathleen C. Gerbasi

Faculty Publications

In two studies, we examine ingroup favoritism within the furry community. Furry fans construct personas (“fursonas”) that are often related to a species of animal (e.g., fox, wolf). In Study 1, furries were found to rate their fursona species more favorably than other species. In Study 2, we examined whether the ingroup projection model may aid in understanding this ingroup species bias. Participants’ ratings of prototypicality of their species within the fandom was associated with greater favoritism of one’s species. A serial mediation model showed that identification with the fursona and perceived benefits of one’s fursona mediated the association between …

Natural Nutrient Sources In The Cache River Watershed, Arkansas, M. K. Kilmer, N. Poe, S. Chappell, J. L. Bouldin

Journal of the Arkansas Academy of Science

The growth of the hypoxic ‘dead zone’ in the Gulf of Mexico in recent years has placed increased focus on potential sources of nutrient pollution, with most of the focus being placed on watersheds where practices, including fertilizer application and land alterations combine to increase non-point source runoff. In this study, nutrient concentrations in surface waters of altered and unaltered areas of the Cache River Watershed, Arkansas, were compared to determine if agricultural land usage was responsible for the majority of nutrient inputs. Results suggest that for dissolved nitrites and orthophosphates, agricultural (altered) sites contribute significantly more than relatively unaltered …

Red Crossbill Invasion Of Northwestern Arkansas During 2012-2013, K. G. Smith, J. C. Neal, M. A. Young

Journal of the Arkansas Academy of Science

An irruption of Red Crossbills (Loxia curvirostra) occurred in primarily northwestern Arkansas starting in November of 2012 and lasting to the end of May of 2013. Based on recordings of call notes, most birds around Fayetteville were Type 2, the large-billed ponderosa pine crossbill, associated with a variety of conifer species. Birds recorded in Carroll County were Type 3, the small-billed western hemlock crossbill, and they were associated with small cones on shortleaf pine (Pinus echinata). One recording was obtained in Fayetteville of Type 5, the lodgepole pine crossbill, only the third recording east of the Great Plains. Crossbills at …

Still Fighting After All These Years: Minority Voting Rights 50 Years After The March On Washington, Deborah N. Archer

Faculty Articles

In August 2013, we celebrated the 50th Anniversary of the March on Washington and Dr. Martin Luther King, Jr.’s “I Have A Dream” speech. On August 28, 1963, over 250,000 people converged on the National Mall to fight for “jobs and freedom.” A central demand of the marchers was the passage of meaningful civil rights legislation, including laws to end discrimination in voting and to free African Americans from the chains of “political and economic slavery.” The march culminated with Dr. King’s “I Have A Dream” speech in which he pronounced: “[w]e cannot be satisfied as long as the Negro …

Maestros De La Manipulación: Titiriteros De La Memoria Histórica En No De Pablo Larraín Y La Niña De Tus Ojos De Fernando Trueba / Master Manipulators: Puppeteers Of Historical Memory In No By Pablo Larraín And The Girl Of Your Dreams By Fernando Trueba, Polly J. Hodge

World Languages and Cultures Faculty Articles and Research

Se exploran dos obras cinematográficas, No de Pablo Larraín y La niña de tus ojos de Fernando Trueba, en función de sus raíces literarias y el concepto de la memoria histórica. Las obras basadas en eventos históricos intensos y violentos tienen la capacidad de retratar la dialéctica entre la memoria y la amnesia histórica. De esta manera se estimula el impulso por desenmascarar los sistemas de poder y dialogar con la sociedad actual. En el proceso, se descubren soluciones alternativas a la violencia para tratar los problemas políticos.

Caribbean Heat Threatens Health, Well-Being, And The Future Of Humanity, Cheryl C. Macpherson, Muge Akpinar-Elci

Community & Environmental Health Faculty Publications

Climate change has substantial impacts on public health and safety, disease risks and the provision of health care, with the poor being particularly disadvantaged. Management of the associated health risks and changing health service requirements requires adequate responses at local levels. Health-care providers are central to these responses. While climate change raises ethical questions about its causes, impacts and social justice, medicine and bioethics typically focus on individual patients and research participants rather than these broader issues. We broaden this focus by examining awareness among health-care providers in the Caribbean region, where geographic and socioeconomic features pose particular vulnerabilities to …

The Intersection Of Women, Aestheticism And Dance In The Scripps College Dance Department, Christiana K. Ho

Scripps Senior Theses

This is a creative writing: nonfiction thesis investigating how the Scripps College Dance Department came to be and serves a testament to the tenacity of the Scripps College Dance Department. This thesis explores different interconnected histories, regarding women's bodies, women's colleges and dance pioneers at the turn of the twentieth-century, to help explain why dance has the place it does in higher education, offering dance as a space for aestheticism in academia and focusing on the particular intersection of dance, aestheticism and women in a dance department at a women's college. Perhaps by looking at these histories, the current state …

Development Of A Novel Wet Algal Lipid Extraction Technique, Chen Zhang

Theses

A novel procedure, ASAPALLE, for lipid extraction from wet algae, Nannochloropsis Salina, was developed and reported. This method does not require pre-dehydration of algal biomass and the total extraction time needed is under one minute. The ASAPALLE extraction was compared with hexane Soxhlet extraction to evaluate the lipid extraction efficiency and the lipid profile. Algal lipid yield of the ASAPALLE extraction was 14.3% of the total dry algal biomass weight, while the hexane Soxhlet extraction after 18 hours yielded 7.9% of algal lipid. The total lipid content was approximately 14.6%, determined by a modified Bligh-Dyer method. The quality of the …

Phytochemical Analysis Of Antileishmanial Plants : A Drug Discovery Approach, Samon Shrestha

Theses

Phytochemical analysis of three antileishmanial plants from Monteverde, Costa Rica and Abaco Island, Bahamas, has been carried out by use of column chromatography for phytoseparation, and NMR and IR spectroscopy for structural elucidation. Ruyschia phylladenia contained betulinic acid as major component, with significant amount of lupeol. Eugenia monteverdensis contained beta-Sitosterol, betulinic acid and barbinervic acid. Tabebuia bahamensis contained large amount of ursolic acid. Betulinic acid inhibited promastigotes of L. amazonensis significantly but was also toxic to mouse macrophages. Lupeol and betulinic acid did not show antimicrobial activity while beta-Sitosterol inhibited Aspergillus niger strongly. Barbinervic acid expressed good inhibition of Bacillus …

Efficient Spherical Parameterization For Feature Aligned Mesh Morphing, Sabin Timalsena

Theses

This study presents an approach for establishing surface correspondence between multiple genus zero triangle meshes and animating a morph between them. The concepts of mesh simplification and refinement are used to progressively parameterize meshes using a novel metric for measurement of distortion in parameterized triangles. The parameterization algorithm is quite efficient and can process tens of thousands of triangles per minute. Feature correspondence is established between meshes through a two-step feature alignment procedure that aligns user selected features in the parametric domain. The parameterizations are used to merge the shapes from input models in order to generate a single mesh …

Multispectral Remote Sensing Of Archaeological Features In The Chicama Valley, Peru, Claire Christine Herdy

Theses

Around 100 A.D. a regional culture emerged on the north coast of Peru in the Moche Valley that lasted for several centuries. Today called the Moche or Mochica, it is considered on of the earliest states to emerge in the valleys of the Andes. The environment the Moche flourished in is one of extremes, from high deserts in the Andes to lush river valleys and an unforgiving coastline that overlooks the pacific Ocean, In this harsh environment the Moche grew and succeeded partly because of their achievement in advanced irrigation technology. How did the ancient Moche adapt to a desert …

Cognitive Studies On A Mouse Model Of Tyrosinemia Type I, Sarah Bradham Coker

Theses

Hereditary Tyrosinemia Type 1 (TTI) is an autosomal recessive disorder that is characterized by the deficiency of the fumarylacetoacetase (FAH) enzyme in the tyrosine catabolic pathway, resulting in the elevation of tyrosine and its byproducts in the blood, cerebrospinal fluid (CSF), and tissues. The accumulation of the toxic metabolites succinylacetone and fumarylacetoacetate in the liver and kidneys leads to catastrophic effects and death if not treated. The current treatments available for TTI patients are pharmacotherapy with nitisinone (NTBC) with diet modification and/or a liver transplant, each with its own associated risks. Recently, data has been published showing that TTI patients …

Theses

Yemen is a small country located in the southwestern part of the Arabian Peninsula. Yemen’s coastal lowlands, eastern plateau and deserts give it a diverse topography, which along with climatic factors make it opulent in flora. Despite the introduction of western medicinal system during the middle of the twentieth century, herbal medicine still plays an important role in Yemen. However, little has been done on the study of the aromatic medicinal plants that have been used through ages to cure and heal diseases. To this end, in collaboration with Deparment of Pharmacognosy, Faculty of Pharmacy, Sana’a University, Yemen the essential …

Conversion Of Neural Network Models To State-Space Models For Model-Based Control Design, Sai Susheel Praneeth Kode

Theses

The objective of this research is to implement an artificial neural network into a closed-loop model based control law that requires a state space model. Model based control laws are strongly preferred due to the existence of mathematical proofs for their performance. With mathematical proof of performance, the controller is guaranteed to work correctly within a designed domain of operation. However, deriving physics based mathematical models and accurately identifying the parameters of such models are cumbersome, or sometimes impossible, for complex nonlinear systems. This limits the application domain of model based controllers. Neural networks are a great tool for modeling …
