Unleashing The Potential Of Film, Allan R. Staker, Stanley Ferguson

Journal of Undergraduate Research

When I applied for the ORCA Grant last year, I wanted to distribute a film project outside the boundaries of BYU and the University’s “FINAL CUT Student Film Festival.” In order to do so, I began to adapt the ideas pre-selling feature films to major studios that Professor John Lee taught in “TMA 389: Producer’s Practicum” to my own hypothetical process of selling a documentary series to a national cable network.

Thomas Hardy, Christian Bryner, John Bennion

Journal of Undergraduate Research

For Professor Bennion’s Thomas Hardy project, I used my alloted 80 hours to research cultural and geographical information from five different novels: Jude the Obscure, The Return of the Native, The Mayor of Casterville, Tess of the d’Urbervilles, and Under the Greenwood Tree. With each of the novels, I jotted down the page number of any reference to geographical locations, place names, descriptions of local history, references to local customs, songs, buildings, furniture, local plant and animal life, and clothing.

Short-Term Effects Of Dietary Phytoestrogens On Calbindin, Calretinin, And Cox-2 In Specific Brain Sites Of Male Rats, Melanie A. Watson, Dr. Edwin D. Lephart

Journal of Undergraduate Research

Cyclooxygenase, a bifunctional enzyme, converts arachadonic acid to prostaglandins that are important for maintaining critical physiological functions such as nervous system regulation, pain response, and specifically inflammation of tissues. The enzyme exists in two isoforms: COX-1 is constitutionally produced, playing important maintenance roles throughout the body. COX-2 is constitutionally produced in the brain, but is inducible and thus, highly regulated (2). Non-specific inhibition of COX reduces inflammation, but increases gastrointestinal ulcers due to a failure of mucus production by COX-1. Specific COX-2 inhibition controls the inflammatory response, but is not ulcergenic (1,3). At this time the effect of COX-2 regulation …

A Fine Structure Comparison Of Three Species Of Argulus (Crustacea: Branchiura) Ectoparasites Of Farmed And Wild Fish, Adam Bowen, Richard A. Heckmann

Journal of Undergraduate Research

Argulus, commonly called fish-lice, are crustacean ectoparasites of fish. This study compared three members of the genus Argulus: A. pugetensis from Nanaimo, British Columbia; A. coregoni from Curitiba, Brazil; and A. siamensis from Bangalore, India. It was hypothesized that argulids of different taxons must have morphological variations of commonly held structures. For example, two species of Argulus possess marginal membranes on their suckers, but the membranes should have different quantities and qualities of substructures. To test this hypothesis, all specimens were photographed with the JEOL 6100 scanning electron microscope; the micrographs of A. pugetensis and A. siamensis are the first …

Dotpopulation Genetic Analysis Of Puma Concolor Using Microsatellites, Eric Swenson, Dr. Keith A. Crandall

Journal of Undergraduate Research

The mountain lion, Puma concolor, is the last widespread species of top predator remaining in the United States (2). Despite this, P. concolor is the subject of annual hunts, except in Florida and South Dakota, where they are threatened, and California (4). The impact of hunting on these populations is not well understood, but sport hunting constitutes the highest source of mortality in Utah (5). Indications are that increased hunting activity over the past few years may be causing a decline in the P. concolor population in Utah (1). The impact of hunting practices on the genetic variation of mountain …

Scanning Electron Microscopy Of Early Infection Of Dyers Woad, Isatis Tinctoria By Germlings Of Puccinia Thlaspeos, Michael T. Binns, Dr. Gary R. Hooper

Journal of Undergraduate Research

Dyers Woad (Isatis tinctoria) is an introduced noxious weed of crop and rangeland in northern Utah. A native rust fungus (tentatively identified as Puccinia thlaspeos) is being investigated as a possible biological control agent of the weed. In order to effectively use the rust in a biocontrol program, it is necessary to understand its epidemiology and characteristics.

Odocoileus Hemionus Mortality Profiles And The Cultural Predatory Adaptations At Aspen Shelter, Utah, James T. Anderson, Dr. Joel C. Janetskik

Journal of Undergraduate Research

Mortality profiles (ages at death) constructed from the faunal analysis of archaeological sites offer unique insights into specific cultural predatory patterns and lifeways of the sites former inhabitants. The products of prey age selection or mortality profiles allow archaeologists to understand strategies of hunting, land use, and “habitual techniques of procurement” . A mortality profile of 4 mule deer (Odocoileus hemionus) was created from the thousands of identified bones excavated at Aspen Shelter, Utah in an attempt to understand such cultural adaptations.

Cardiac Fibroblast-Dependent Extracellular Matrix Accumulation Is Associated With Diastolic Stiffness In Type 2 Diabetes., Kirk R. Hutchinson, C. Kevin Lord, T. Aaron West, James A. Stewart

CAS Publications

Cardiovascular complications are a leading cause of death in patients with type 2 diabetes mellitus (T2DM). Diastolic dysfunction is one of the earliest manifestations of diabetes-induced changes in left ventricular (LV) function, and results from a reduced rate of relaxation and increased stiffness. The mechanisms responsible for increased stiffness are not completely understood. Chronic hyperglycemia, advanced glycation endproducts (AGEs), and increased levels of proinflammatory and profibrotic cytokines are molecular pathways known to be involved in regulating extracellular matrix (ECM) synthesis and accumulation resulting in increased LV diastolic stiffness. Experiments were conducted using a genetically-induced mouse model of T2DM generated by …

Histological And Ultrastructural Evidence Of Osteoarthritis In Mice Carrying A Semi-Dominant Mutation Of Col2a1, Victoria Ryder, Dr. Robert Seegmiller

Journal of Undergraduate Research

Mice heterozygous for the semi-dominant mutation disproportionate micromelia (Dmm) express mild chondrodysplasia by three weeks postnatally. This phenotype is attributed to a deletion of three contiguous nucleotides within the Col2A1 gene on mouse chromosome 15. The phenotype of Dmm/+ mice resembles that of human Stickler syndrome, which can be caused by mutations in the human COL2A1 gene.

Summary Of Research And Writing The Screenplay “Cora Chattering” Based On Terrie Petree’S Award-Winning Short Story “Eating The Old Thoughts”, Ethan L. Vincent, Stan Ferguson

Journal of Undergraduate Research

Research and writing “Cora Chattering” was an interesting process. Terrie Petree’s seven page short story “Eating the Old Thoughts” offered enough material for a 21 page script, translating into approximately 20 minutes screen time – the ideal length for a student short film. Although the script diverts somewhat from Terrie Petree’s original story, these necessary changes made the characters and their relationships to each other more animated and accessible. As a result, I learned a great deal about the compromises of short story adaptations.

Few-View Single Photon Emission Computed Tomography (Spect) Reconstruction Based On A Blurred Piecewise Constant Object Model, Paul Arthur Wolf, Jakob S. Jørgensen, Taly Gilat Schmidt, Emil Y. Sidky

Biomedical Engineering Faculty Research and Publications

A sparsity-exploiting algorithm intended for few-view single photon emission computed tomography (SPECT) reconstruction is proposed and characterized. The algorithm models the object as piecewise constant subject to a blurring operation. To validate that the algorithm closely approximates the true object in the noiseless case, projection data were generated from an object assuming this model and using the system matrix. Monte Carlo simulations were performed to provide more realistic data of a phantom with varying smoothness across the field of view and a cardiac phantom. Reconstructions were performed across a sweep of two primary design parameters. The results demonstrate that the …

Neighborhood Commercial Corridor Change: Portland, Oregon 1990-2010, Kelly Ann Howsley-Glover

Dissertations and Theses

Commercial corridors in neighborhoods experiencing change have been relegated to a footnote in research on residential phenomena. It is taken for granted that the process of change experience by businesses within these neighborhoods mirrors that of the residential change. This assumption is often predicated on the underlying model of invasion succession, suggesting that inmovers displace native populations, whether they are residents or businesses. Analyzing time series data on neighborhood commercial corridor change, research attempted to first test data against the invasion succession model to see if it is an effective framework for analysis. Second, through comparison of case study areas …

Funerary Stela Of Heni, Risd Museum, Antoine Revoy, James Allen

Channel

Offered symbolically, the images and hieroglyphics depicted on the right of this funerary stela ensured that Heni, a local high official, would never experience hunger or thirst in the afterlife. The slightly awkward proportions of Heni’s figure are typical of monuments of the First Intermediate period, when there was no centralized government in Egypt. The lack of royal control over artistic production during this time allowed artists to experiment, as seen in the multiple levels of relief on Heni’s kilt, the particular green of the hieroglyphs, and the striped border. 2134-2040 BCE

Patterns Of Anti-Muslim Violence In Burma: A Call For Accountability And Prevention, Andrea Gittleman, Marissa Brodney, Holly G. Atkinson

In this report, the authors documents how persecution of and violence against the Rohingya in Burma has spread to other Muslim communities throughout the country. Physicians for Human Rights conducted eight separate investigations in Burma and the surrounding region between 2004 and 2013. PHR’s most recent field research in early 2013 indicates a need for renewed attention to violence against minorities and impunity for such crimes. The findings presented in this report are based on investigations conducted in Burma over two separate visits for a combined 21-day period between March and May 2013.

Low Seroprevalent Species D Adenovirus Vectors As Influenza Vaccines, Eric A. Weaver, Michael A. Barry

School of Biological Sciences: Faculty Publications

Seasonal and pandemic influenza remains a constant threat. While standard influenza vaccines have great utility, the need for improved vaccine technologies have been brought to light by the 2009 swine flu pandemic, highly pathogenic avian influenza infections, and the most recent early and widespread influenza activity. Species C adenoviruses based on serotype 5 (AD5) are potent vehicles for gene-based vaccination. While potent, most humans are already immune to this virus. In this study, low seroprevalent species D adenoviruses Ad26, 28, and 48 were cloned and modified to express the influenza virus A/PR/8/34 hemagglutinin gene for vaccine studies. When studied in …

Can't Hold Me Back! Constraint-Induced Movement Therapy For Children With Cp: Evidence Based Review, Rebecca Coale, Danni Eisner, Alissa Herman, Sarah Merhaut

Collaborative Research and Evidence shared Among Therapists and Educators (CREATE Day)

Children with cerebral palsy (CP) have various functional impairments impacting participation in meaningful occupations. While Constraint-Induced Movement Therapy (CIMT) is a widely used intervention for adult populations, a modified version of this technique is a relatively new practice in pediatrics (Charles et al., 2006). Occupational therapy intervention, such as CIMT, can support functional goal attainment to enhance participation and quality of life (Boyd et al., 2010). The purpose of this presentation is to synthesize results of a comprehensive evidence-based review and identify treatment characteristics that impact efficacious use of mCIMT on children with hemiplegic CP. Practitioners will learn about best …

Thimerosal Exposure And The Role Of Sulfation Chemistry And Thiol Availability In Autism, Janet K. Kern, Boyd E. Haley, David A. Geier, Lisa K. Sykes, Paul G. King, Mark R. Geier

Chemistry Faculty Publications

Autism spectrum disorder (ASD) is a neurological disorder in which a significant number of the children experience a developmental regression characterized by a loss of previously acquired skills and abilities. Typically reported are losses of verbal, nonverbal, and social abilities. Several recent studies suggest that children diagnosed with an ASD have abnormal sulfation chemistry, limited thiol availability, and decreased glutathione (GSH) reserve capacity, resulting in a compromised oxidation/reduction (redox) and detoxification capacity. Research indicates that the availability of thiols, particularly GSH, can influence the effects of thimerosal (TM) and other mercury (Hg) compounds. TM is an organomercurial compound (49.55% Hg …

Recruitment And Survival Of Post-Parasitic Juvenile Mussels In An East Texas River, David S. Bakkin

Biology Theses

Freshwater mussels (order Unionoida) are the most imperiled group of fauna in North America. The factors driving this decline chiefly affect juvenile recruitment and survival, rather than adult mortality. However, our present knowledge generally consists of inferences from studies of adult distributions. Juvenile mussels are rarely collected in the field, leaving our understanding of this critical period in the mussel life cycle incomplete. Popular hypotheses, most notably that shear stress during floods scours small mussels from the substrate and largely confines mussel beds to sheltered areas, are supported by circumstantial evidence and have rarely been tested directly. The role of …

Cytotoxicity Study Of Iron Oxide Nanoparticles, Single-Wall Carbon Nanotubes And Their Complexes Applied To Mcf7 Breast Cancer Cells, Karine Mege

Theses and Dissertations

Reactive Oxygen Species (ROS) are radicals of great concern to biologists. Their role in several diseases--such as neurodegenerative disease, diabetes, premature aging and cancer--has been intensively investigated during the last decade. Since a major focus in cancer research is to better understand how it is induced and therefore how it can be cured, the study of the cytotoxic effects of ROS production within cancer cells is vital. Nanotechnology is an emerging field of science that promises great improvements in a number of disciplines. Nano medicine is one of its daughter fields. Various nanomaterials are used for diagnosis and disease detection, …
