The Effects Of Hyaluronic Acid And Glucosamine On The Migration And Proliferation Of Tenocytes, Chien-Hung Chen, Jin-Fu Huang, Li-Lun Chen, Wen-Chung Tsai, Jong-Hwei S. Pang, Yu-Hsin Liao, Tung-Yang Yu

Rehabilitation Practice and Science

Tendinopathy or tendon rupture is a common disease. Studies have showed that hyaluronic acid and glucosamine benefit the process of tendon repair. Tendon healing requires the migration of tenocytes to the repair site, followed by the proliferation and synthesis of the extracellular matrix. However, the effects of hyaluronic acid and glucosamine on tenocytes remain to be explored. Here, we treated tenocytes from rat Achilles tendons with hyaluronic acid or glucosamine. The ability of tenocytes to migrate and proliferate was assessed by transwell filter migration assay and MTT (3-[4,5-Dimethylthiazol-2-yl]-2,5- diphenyltetrazolium bromide) assay, respectively. Results from transwell filter migration assays showed that …

Partitioning The Fitness Components Of Rna Populations Evolving In Vitro, Carolina Diaz Arenas, Niles Lehman

Chemistry Faculty Publications and Presentations

All individuals in an evolving population compete for resources, and their performance is measured by a fitness metric. The performance of the individuals is relative to their abilities and to the biotic surroundings – the conditions under which they are competing – and involves many components. Molecules evolving in a test tube can also face complex environments and dynamics, and their fitnessmeasurements should reflect the complexity of various contributing factors as well. Here, the fitnesses of a set of ligase ribozymes evolved by the continuous in vitroevolution system were measured. During these evolution cycles there are three different catalytic …

The Regulation Of Prospore Membrane Shape In Saccharomyces Cerevisiae, Emily M. Parodi

Graduate Doctoral Dissertations

The size and shape of a membrane is an important determinant in cell morphology. My work focuses on how membrane size and shape is determined, using the budding yeast S. cerevisiae as a model. During sporulation in S. cerevisiae, the diploid cell remodels its interior such that four spores are formed within an ascus. During this remodeling process, the prospore membrane is synthesized de novo and grows to surround each of the meiotic products. The prospore membrane is a double lipid bilayer and ultimately determines the sizes and shapes of the newly formed spores. My work focuses on the …

Influence Of Boulders On Netleaf Hackberry (Celtis Reticulata) Growth And Distribution In The Wasatch Foothills, Alex Argyle, Michael T. Stevens

Western North American Naturalist

In a landscape, abiotic features, such as boulders, influence microhabitats and consequently affect patterns of vegetation. We hypothesized that boulders in the foothills of the Wasatch Mountains east of Provo, Utah, affected the growth patterns of netleaf hackberry (Celtis reticulata) by providing shade on their north faces. To test this hypothesis, we set up 3 transects 6 m wide and up to 50 m long. Along these transects, we measured all hackberries taller than 30 cm (n = 249). We recorded whether the hackberries grew within 0.5 m of a boulder that was at least 0.5 m …

Helminths Of The Speckled Rattlesnake, Crotalus Mitchellii (Squamata: Viperidae), Stephen R. Goldberg, Charles R. Bursey, Xavier Glaudas

Western North American Naturalist

Fifty-six speckled rattlesnakes, Crotalus mitchellii, from western North America were examined for helminths. One species of Cestoda (tetrathyridia of Mesocestoides sp.) and 5 species of Nematoda (gravid adults of Abbreviata terrapenis, Physaloptera abjecta, Thubunaea cnemidophorus, and Travassoascaris araujoi and larvae ofPhysocephalus sp.) were found. Travassoascaris araujoi had the highest prevalence and greatest mean intensity of helminths infecting C. mitchellii. Three new host records forC. mitchellii are reported. As has been reported for other North American rattlesnakes,C. mitchellii is parasitized by “generalist” helminths.

From Cultural Third-Worldism To The Literary World-System, Jernej Habjan

CLCWeb: Comparative Literature and Culture

In his article "From Cultural Third-Worldism to the Literary World-System" Jernej Habjan links the debate on Franco Moretti's distant reading to the debate on Fredric Jameson's "third world culture." In and around this debate, Aijaz Ahmad both critiqued close reading and rejected Jameson's "Third-Worldism." What Jameson's and Ahmad's interventions into literary theory meant at the end of the real-socialist alternative and what Moretti's meant at the end of the US-American alternative to real-socialism, a synoptic reading of all three interventions might help achieve at the end of what seemed the European alternative to the US-American alternative.

Artaud, Barney, And The Total Work Of Art From Avant-Garde To The Posthuman, Matteo Colombi, Massimo Fusillo

CLCWeb: Comparative Literature and Culture

In their article "Artaud, Barney, and the Total Work of Art from Avant-Garde to the Posthuman" Matteo Colombi and Massimo Fusillo discuss the aesthetics of Matthew Barney's video-performance art and the theater of Antonin Artaud. Colombi and Fusillo highlight the characteristics of the posthuman: the rejection of Western anthropocentrism and its subversion through hybridization with human, animal, and mechanical elements, the incorporation of Dionysian imagery of the body, and a commitment to the idea of the total work of art in its blending of different artistic mediums, and indeed, of art and life. Using examples from Artaud's writings on theater, …

Long-Distance Movement In A Dusky Great Horned Owl And Limits To Phylogeography For Establishing Provenance, Robert W. Dickerman, Sabrina M. Mcnew, Christopher C. Witt

Western North American Naturalist

The Dusky Great Horned Owl (Bubo virginianus saturatus) of the Pacific Northwest region of North America is generally considered to be nonmigratory. Here we report a specimen of a Dusky Great Horned Owl that was salvaged in New Mexico and identified based on comparison of its plumage with a large series of museum skins. We attempted to corroborate this identification by comparing mitochondrial DNA sequences between the specimen and a representative sample of 5 Great Horned Owl subspecies from western North America. This analysis revealed minimal mitochondrial genetic variation and no evidence of population genetic structure, suggesting that …

Evaluating Survival Of Greater Sage-Grouse Chicks In Strawberry Valley, Utah, By Use Of Microtransmitters: Does Handling Time Negatively Influence Survival Rates?, Jared J. Baxter, Jordan P. Hennefer, Rick J. Baxter, Randy T. Larsen, Jerran T. Flinders

Western North American Naturalist

Research indicates that low nest success and juvenile survival may be factors contributing to Greater Sage-Grouse population declines. Recent technological advances in microtransmitters have allowed researchers to monitor individual chicks and broods. We initiated a chick survival study in 2006 and used microtransmitters to (1) examine the viability of using microtransmitters on chicks to assess survival, including the effect of handling time during the suturing process; (2) estimate overall chick survival; and (3) compare chick survival in the Strawberry Valley population to other published reports. We used a known-fate model in program MARK to estimate ĉ (overdispersion), weekly survival rates, …

Impact Of Livestock Grazing On Plant And Small Mammal Communities In The Ruby Mountains, Northeastern Nevada, Eric A. Rickart, Klaus G. Bienek, Rebecca J. Rowe

Western North American Naturalist

We assessed the effects of livestock grazing on vegetation and small mammals in semiarid habitat at a site in northeastern Nevada. Habitat within a fenced exclosure that had been protected from grazing for more than 50 years supported more vegetation and had greater plant diversity compared to habitat immediately outside the exclosure. Likewise, species richness and abundance of small mammals were greater in ungrazed areas. Results suggest that grazing regulation in recent decades may account for some of the changes seen in regional plants and small mammals over the past century. The incorporation of long-term exclosures in a comparative framework …

Impacts Of U.S. Biofuels Mandates On Environmental And Energy Security, Mohammad Alshawaf

Graduate Doctoral Dissertations

Congress passed the Energy Policy Act of 2005 and the Energy Independence and Security Act (EISA) of 2007 to reduce dependency on foreign oil by increasing the use of biofuels. EISA mandates 36 billion gallons of biofuel production in 2022, representing an increase of 118% in eight years. Existing and new farmland are expected to be employed to produce corn and other feedstock necessary to fulfill the biofuel mandate. There is little research on the potential environmental impact on water resources of meeting the ESIA biofuel mandates.

The objectives of this EISA study were twofold. First, the study measured the …

Maternal Self-Efficacy And Perceived Stigma Among Mothers Of Children With Asd, Adhd, And Typically Developing Children, Sara D. Rosenblum-Fishman

An Optogenetic Gene Expression System With Rapid Activation And Deactivation Kinetics, Laura B. Motta-Mena, Anna Reade, Michael J. Mallory, Spencer Glantz, Orion D. Weiner, Kristen W. Lynch, Kevin H. Gardner

Publications and Research

Optogenetic gene expression systems can control transcription with spatial and temporal detail unequaled with traditional inducible promoter systems. However, current eukaryotic light-gated transcription systems are limited by toxicity, dynamic range, or slow activation/deactivation. Here we present an optogenetic gene expression system that addresses these shortcomings and demonstrate its broad utility. Our approach utilizes an engineered version of EL222, a bacterial Light-Oxygen-Voltage (LOV) protein that binds DNA when illuminated with blue light. The system has a large (>100-fold) dynamic range of protein expression, rapid activation (< 10 s) and deactivation kinetics (< 50 s), and a highly linear response to light. With this system, we achieve light-gated transcription in several mammalian cell lines and intact zebrafish embryos with minimal basal gene activation and toxicity. Our approach provides a powerful new tool for optogenetic control of gene expression in space and time.

Host Selection Of Spring Tiphia (Tiphia Vernalis) And Summer Tiphia (Tiphia Popilliavora), Natural Enemies Of Japanese And Oriental Beetles, Piyumi T. Obeysekara

Doctoral Dissertations

Japanese beetle, Popillia japonica Newman, and oriental beetle, Anomala orientalis (Waterhouse) (Coleoptera: Scarabaeidae) are major turfgrass pests in United States. Tiphia vernalis Rohwer and Tiphia popilliavora Rohwer (Hymenoptera: Tiphiidae) were introduced as biocontrol agents against these beetles. To test the attractiveness of Tiphia wasps to herbivore induced plant volatiles, two choice bio assays were conducted. Results showed that both T. vernalis and T. popilliavora were strongly attracted to volatiles emitted by grub-infested tall fescue (Festuca arundinacea Schreb.) and Kentucky bluegrass (Poa pratensis L.) over healthy grasses. The elevated levels of terpenes emitted by grub-infested Kentucky bluegrass and tall …

In Ambiguous Battle: The Promise (And Pathos) Of Public Domain Day, 2014, Jennifer Jenkins

Duke Law & Technology Review

On the first day of each year, Public Domain Day celebrates the moment when copyrights expire, and books, films, songs, and other creative works enter the public domain, where they become, in Justice Brandeis’s words, “free as the air to common use.” Educators, students, artists, and fans can use them with neither permission nor payment. Online archives can digitize and make them fully available without the threat of lawsuits or licensing demands. Sadly, in the United States, as a result of copyright term extensions, not a single published work will enter the public domain in 2014. In fact, almost no …

An Investigation Of Electro-Optical 1/F Noise Reduction In An Open-Path Tunable Diode Laser Spectrometer, Samira Adnan Mahdi

Theses and Dissertations

A mobile spectrometer system has been designed to scan the near-surface atmosphere for ammonia gas over a wide range of distances (10 m to 1 Km). Since the system is designed for space applications, it needs to be small, light weight, and low power, which dictates the use of relatively low frequency measurement scans. The spectrometer uses a diode laser, which is subject to a large of electro-optical 1/f noise component at these low frequencies. In this work, digital signal processing techniques are developed to reduce the effects of 1/f noise in gas measurements. A Double Fast Fourier Transform-Based Filter …
