Gp130 Cytokines Exert Differential Patterns Of Crosstalk In Adipocytes Both In Vitro And In Vivo, Ursula A. White, William C. Stewart, Jacqueline M. Stephens May 2011

Gp130 Cytokines Exert Differential Patterns Of Crosstalk In Adipocytes Both In Vitro And In Vivo, Ursula A. White, William C. Stewart, Jacqueline M. Stephens

Faculty Publications

Glycoprotein 130 (Gp130) cytokines are involved in the regulation of numerous biological processes, including hematopoiesis, immune response, inflammation, cardiovascular action, and neuronal survival. These cytokines share gp130 as a common signal transducer in their receptor complex and typically activate signal transducer and activator of transcription (STAT) 3. Studies have shown that several gp130 cytokines have differential effects on both adipogenesis and insulin-stimulated glucose uptake. Yet, the complex interactions of these cytokines in adipose tissue have not been studied. Gp130 cytokines are differentially regulated in multiple tissues due to the presence of additional receptor components that are required for signaling, including …

On The Cutting Edge: Post-Translational Modifications In Cytokinesis, K. Adam Bohnert, Kathleen L. Gould May 2011

On The Cutting Edge: Post-Translational Modifications In Cytokinesis, K. Adam Bohnert, Kathleen L. Gould

Faculty Publications

Cytokinesis represents the final stage in the cell cycle, in which two daughter cells, each with their complement of the duplicated genome, physically separate. At the core of this process sits highly conserved machinery responsible for specifying the plane of division, building a contractile apparatus and ultimately cleaving cells in two. Although the 'parts list' of contributing proteins has been well described, mechanisms by which these parts are spatially and temporally regulated are only beginning to be understood. With advancements in biochemical and proteomic analyses, recent work has uncovered multiple new roles for post-translational modifications in the regulation of cytokinesis. …

Stable Isotopes Provide Insight Into The Use Of Wildlife Water Developments By Resident And Migrant Birds In The Sonoran Desert Of Arizona, Theresa C. Hyde May 2011

Stable Isotopes Provide Insight Into The Use Of Wildlife Water Developments By Resident And Migrant Birds In The Sonoran Desert Of Arizona, Theresa C. Hyde

Biology ETDs

Several studies have looked at the importance of man-made water resources to wildlife in desert regions. To our knowledge, however, none have attempted to directly quantify their importance to both resident and Neotropical migratory birds. During the spring and summer from 2007-2009, we enriched man-made water developments in the Sonoran Desert on the Kofa National Wildlife Refuge, Arizona. We enriched water developments using deuteriated water and sampled the body water pools of resident and migrant birds to quantify development use. We used a simple two end-point mixing model to estimate the proportion of an individual birds body water pool that …

Divergence In The Ecology Of Two Species Of Gambusia In Secondary Contact, Daniella Marilyn Swenton May 2011

Divergence In The Ecology Of Two Species Of Gambusia In Secondary Contact, Daniella Marilyn Swenton

Biology ETDs

Gambusia nobilis, a federally endangered species, and G. affinis (Poeciliidae) are small, livebearing fishes found in the southwestern U.S. The invasive G. affinis has been introduced globally to control mosquito populations. It is found in some populations of G. nobilis on Bitter Lake National Wildlife Refuge (BLNWR), the field site for this study. It is unclear to what extent the two species have diverged in behavior and ecology and how extensively they have hybridized on BLNWR, thereby threatening the endangered G. nobilis via genetic introgression. In this study I examined divergence in behavior and ecology between two species with four …

From Growth To Extinction: Explored By Life History And Metabolic Theory, Wenyun Zuo May 2011

From Growth To Extinction: Explored By Life History And Metabolic Theory, Wenyun Zuo

Biology ETDs

The laws of energy and material conservation are fundamental principles across various scales and systems. Based on the conservation laws, I derive several theoretical models to understand mechanisms behind the energy budget of ontogenetic growth and the pattern of the late Pleistocene extinction of megafauna in the Americas. First, I present a model, empirically grounded in data from birds and mammals, that correctly predicts how growing animals allocate food energy between synthesis of new biomass and maintenance of existing biomass. Previous energy budget models have typically been based on rates of either food consumption or metabolic energy expenditure. The model …

The Role Of Diffusion And Membrane Topography In The Initiation Of High Affinity Ige Receptor Signaling, Nicholas L. Andrews May 2011

The Role Of Diffusion And Membrane Topography In The Initiation Of High Affinity Ige Receptor Signaling, Nicholas L. Andrews

Biomedical Sciences ETDs

The high affinity IgE receptor (FcεRI) plays a primary role in the pathogenesis of allergic disease and shares significant similarities with the two other multichain immune recognition receptor family members, the B-cell receptor and T-cell receptor. A wealth of information exists in all three of these receptor systems with regard to the signaling cascades occurring subsequent to receptor activation. It is also known that all three require binding of multivalent antigen to initiate signaling. However, very little is known about the precise mechanism by which multivalent antigen binding initializes downstream signaling. It has long been known that, in response to …

Dynamic Strategic Information Transmission, Mikhail Golosov, Vasiliki Skreta, Aleh Tsyvinski, Andrea Wilson May 2011

Dynamic Strategic Information Transmission, Mikhail Golosov, Vasiliki Skreta, Aleh Tsyvinski, Andrea Wilson

Cowles Foundation Discussion Papers

This paper studies strategic information transmission in a dynamic environment where, each period, a privately informed expert sends a message and a decision maker takes an action. Our main result is that, in contrast to a static environment, full information revelation is possible. The gradual revelation of information and the eventual full revelation is supported by the dynamic rewards and punishments. The construction of a fully revealing equilibrium relies on two key features. The first feature is that the expert is incentivized, via appropriate actions, to join separable groups in which she initially pools with far-away types, then later reveals …

Bmi Trajectories During The Transition To Older Adulthood: Persistent, Widening, Or Diminishing Disparities By Ethnicity And Education?, Katrina M. Walsemann, Jennifer A. Ailshire May 2011

Bmi Trajectories During The Transition To Older Adulthood: Persistent, Widening, Or Diminishing Disparities By Ethnicity And Education?, Katrina M. Walsemann, Jennifer A. Ailshire

Faculty Publications

Previous research has produced inconsistent results on whether education and ethnic disparities in BMI persist, widen, or diminish over time. We investigate how education and ethnicity, independently and conditionally, influence BMI trajectories during the transition to older adulthood. Employing random coefficient modeling, we analyzed 8 biennial waves of data (1992-2006) from the Health and Retirement Study, a nationally representative longitudinal study of individuals born between 1931 and 1941. After adjusting for health behaviors and health status, education and ethnic disparities in BMI persisted for most groups, but narrowed between high-educated white men and both low-educated Hispanic men and high-educated black …

Regulation Of Spreading Depression Events In Brain Slices By Astrocyte Metabolism, Jessica Lousie Seidel May 2011

Regulation Of Spreading Depression Events In Brain Slices By Astrocyte Metabolism, Jessica Lousie Seidel

Biomedical Sciences ETDs

Spreading depression (SD) is a severe depolarization of both neurons and astrocytes that can propagate throughout CNS tissue. SD has long been associated with migraine, and recent work has strongly suggested that closely related events are likely to be involved in pathophysiological conditions where they provide a large additional metabolic burden to injured tissues. The major goal of this dissertation was to test the overall hypothesis that manipulation of astrocyte metabolic capacity can modify the initiation and propagation of deleterious spreading depression (SD)-like events. If this were the case, then it may support targeting these cells in a range of …

Snap-25 Is A Component Of A Ubiquitous Snare Complex Required For Evoked Neuroexocytosis In Gabaergic Neurons, Lawrence C. R. Tafoya May 2011

Snap-25 Is A Component Of A Ubiquitous Snare Complex Required For Evoked Neuroexocytosis In Gabaergic Neurons, Lawrence C. R. Tafoya

Biomedical Sciences ETDs

The processes of vesicular trafficking and membrane fusion are fundamental to nervous system development and communication among neurons within integrated circuits. The regulated release of several neurotransmitters is dependent on synaptosomal-associated protein 25 kDa (SNAP-25)-containing soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) core complexes. The requirement for this fusogenic machinery in evoked neurosecretion has been repeatedly demonstrated through the use of mutant mouse models and neurotoxin blockades. However, the existence of a functional role for a SNAP-25-containing SNARE complex has not been shown in the major inhibitory neurotransmitter system of the brain, gamma-aminobutyric acid (GABA). To determine whether SNAP-25 participates …

Metabolic Restructuring During Energy-Limited States: Insights From Artemia Franciscana Embryos And Other Animals, Steven C. Hand, Michael A. Menze, Apu Borcar, Yuvraj Patil, Joseph A. Covi, Julie A. Reynolds, Mehmet Toner May 2011

Metabolic Restructuring During Energy-Limited States: Insights From Artemia Franciscana Embryos And Other Animals, Steven C. Hand, Michael A. Menze, Apu Borcar, Yuvraj Patil, Joseph A. Covi, Julie A. Reynolds, Mehmet Toner

Faculty Publications

Many life history stages of animals that experience environmental insults enter developmental arrested states that are characterized by reduced cellular proliferation, with or without a concurrent reduction in overall metabolism. In the case of the most profound metabolic arrest reported in invertebrates, i.e., anaerobic quiescence in Artemia franciscana embryos, acidification of the intracellular milieu is a major factor governing catabolic and anabolic downregulation. Release of ions from intracellular compartments is the source for approximately 50% of the proton equivalents needed for the 1.5 unit acidification that is observed. Recovery from the metabolic arrest requires re-sequestration of the protons with a …

Elevated Corticosterone In Feathers Correlates With Corticosterone-Induced Decreased Feather Quality: A Validation Study, Christine R. Lattin, J. Michael Reed, David W. Desrochers, L. Michael Romero May 2011

Elevated Corticosterone In Feathers Correlates With Corticosterone-Induced Decreased Feather Quality: A Validation Study, Christine R. Lattin, J. Michael Reed, David W. Desrochers, L. Michael Romero

Faculty Publications

The newly described technique of extracting corticosterone (CORT) from bird feathers may serve as a less invasive, more integrated measure of a bird's stress response. Previous work indicated that elevated plasma CORT resulted in poorer quality feathers during molt. We tested the hypothesis that a direct link exists between plasma and feather CORT concentrations. We experimentally increased plasma CORT concentrations using implants and found that the corresponding rise in CORT could be detected in feathers grown during implantation. Furthermore, CORT levels in two feathers grown at the same time from the same bird were very consistent. These results provide evidence …

Nucleotide Sequence Data Confirm Diagnosis And Local Endemism Of Variable Morphospecies Of Andean Astroblepid Catfishes (Siluriformes: Astroblepidae), Scott A. Schaefer, Prosanta Chakrabarty, Anthony J. Geneva, Mark H. Sabaj Pérez May 2011

Nucleotide Sequence Data Confirm Diagnosis And Local Endemism Of Variable Morphospecies Of Andean Astroblepid Catfishes (Siluriformes: Astroblepidae), Scott A. Schaefer, Prosanta Chakrabarty, Anthony J. Geneva, Mark H. Sabaj Pérez

Faculty Publications

Phylogenetic analysis based on nuclear and mitochondrial DNA sequences was used to test the validity of morphospecies of catfishes of the family Astroblepidae inhabiting the southern-most limit of their Andean distribution in the upper Ucayali and upper Madre de Dios river basins. Population samples of morphospecies designated a priori on the basis of morphological features were further diagnosed by the presence of unique and unreversed molecular synapomorphies, thereby confirming species validity for seven of nine cases. Although each are distinguished by unique combinations of morphological features, two morphospecies (designated F and H) cannot be diagnosed on the basis of apomorphic …

Burkholderia Glumae: Next Major Pathogen Of Rice?, Jong Hyun Ham, Rebecca A. Melanson, Milton C. Rush May 2011

Burkholderia Glumae: Next Major Pathogen Of Rice?, Jong Hyun Ham, Rebecca A. Melanson, Milton C. Rush

Faculty Publications

Burkholderia glumae causes bacterial panicle blight of rice, which is an increasingly important disease problem in global rice production. Toxoflavin and lipase are known to be major virulence factors of this pathogen, and their production is dependent on the TofI/TofR quorum-sensing system, which is mediated by N-octanoyl homoserine lactone. Flagellar biogenesis and a type III secretion system are also required for full virulence of B. glumae. Bacterial panicle blight is thought to be caused by seed-borne B. glumae; however, its disease cycle is not fully understood. In spite of its economic importance, neither effective control measures for bacterial panicle blight …

A Model To Predict Evaporation Rates In Habitats Used By Container-Dwelling Mosquitoes, Kristen Bartlett-Healy, Sean P. Healy, George C. Hamilton May 2011

A Model To Predict Evaporation Rates In Habitats Used By Container-Dwelling Mosquitoes, Kristen Bartlett-Healy, Sean P. Healy, George C. Hamilton

Faculty Publications

Container-dwelling mosquitoes use a wide variety of container habitats. The bottle cap is often cited as the smallest container habitat used by container species. When containers are small, the habitat conditions can greatly affect evaporation rates that in turn can affect the species dynamics within the container. An evaporation rate model was adapted to predict evaporation rates in mosquito container habitats. In both the laboratory and field, our model was able to predict actual evaporation rates. Examples of how the model may be applied are provided by examining the likelihood of Aedes albopictus (Skuse), Aedes aegypti (L.), and Culex pipiens …

Wood Consumption By Formosan Subterranean Termites (Isoptera: Rhinotermitidae) As Affected By Wood Moisture Content And Temperature, Bal K. Gautam, Gregg Henderson May 2011

Wood Consumption By Formosan Subterranean Termites (Isoptera: Rhinotermitidae) As Affected By Wood Moisture Content And Temperature, Bal K. Gautam, Gregg Henderson

Faculty Publications

Understanding foraging behaviors and food preferences of termite colonies is critical to optimizing control strategies. The relationship between the moisture content (MC) of wood blocks and the feeding preference of Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae) at three ambient temperatures (19, 28, and 35°C) was investigated with multiple-choice as well as no-choice feeding bioassays. In multiple-choice tests, when four wood blocks with initial MC as dry (0-3%), low MC (22-24%), medium MC (70-90%), and high MC (125-150%) were exposed to workers and soldiers, the highest consumption was found in the high MC wood blocks at all three temperatures, although high MC …

Derrida And The Future(S) Of Phenomenology, Neal Deroo May 2011

Derrida And The Future(S) Of Phenomenology, Neal Deroo

Faculty Work Comprehensive List

This paper seeks to examine the significance of Derrida’s work for an understanding of the basic tenets of phenomenology. Specifically, via an analysis of his understanding of the subject’s relation to the future, we will see that Derrida enhances the phenomenological understanding of temporality and intentionality, thereby moving the project of phenomenology forward in a unique way. This, in turn, suggests that future phenomenological research will have to account for an essential (rather than merely a secondary) role for both linguistic mediation and cultural and political factors within the phenomenological subject itself.

A Contribution To The Vascular Flora Of The Sequatchie Valley Within Sequatchie County, Tennessee, John Richard Evans May 2011

A Contribution To The Vascular Flora Of The Sequatchie Valley Within Sequatchie County, Tennessee, John Richard Evans

Masters Theses and Doctoral Dissertations

The vascular flora of the Sequatchie Valley within Sequatchie County, Tennessee was studied for three growing seasons from 2008 through 2010. The Sequatchie Valley is located within the southeastern portion of the Cumberland Plateau and is generally considered to be part of the Cumberland Plateau Physiographic Province. Nevertheless, a number of geological and ecological factors distinguish the Sequatchie Valley from the elevated Cumberland Plateau, suggesting that the floristic composition of the valley may be different from the surrounding region. Although several previous floristic studies have been conducted on the plateau surface, very little attention has been given to the Sequatchie …

"Not Gone Or Vanished Either:" William Faulker's Use Of Memory And Imagination, Kevin Daniel Gleason May 2011

"Not Gone Or Vanished Either:" William Faulker's Use Of Memory And Imagination, Kevin Daniel Gleason

Masters Theses and Doctoral Dissertations

This thesis examines the role that memory and imagination play in three of William Faulkner’s novels: The Sound and the Fury, Absalom, Absalom! and The Unvanquished. While most scholars perceive Faulkner’s characters as burdened, debilitated, and destroyed by the past, I argue that Faulkner presents a wide spectrum of engagement with the past which includes the potential for memory to serve as a tool of redemption and power. Henri Bergson’s notion of the fluidity of all time past, present, and future forms the center of Faulkner’s understanding of time, and in this paradigm, Faulkner’s characters are capable of creating and …

Influence Of Agricultural Stream Habitat Alterations On Mosquitoes And Amphibians: Patterns, Processes, And Predictions, Julia Sonn May 2011

Influence Of Agricultural Stream Habitat Alterations On Mosquitoes And Amphibians: Patterns, Processes, And Predictions, Julia Sonn

Biology Theses

Changes to stream structure, riparian habitat, and water quality can alter ecosystem dynamics, resulting in an increase in mosquitoes, while weakening populations of amphibians. Therefore, it is necessary to understand how these components are affected by agricultural practices so that mosquito populations can be controlled and aquatic organisms can be protected. In this study, I examined changes in stream structure by measuring geomorphology at three riparian habitats that were anthropogenically impacted to varying degrees. I also compared water quality between the habitats. Mosquitoes and amphibians were surveyed at each riparian habitat, identified to species, and abundances were compared. Stream structure …

An Empirical Comparison Of Four Data Generating Procedures In Parametric And Nonparametric Anova, Anquan Zhang May 2011

An Empirical Comparison Of Four Data Generating Procedures In Parametric And Nonparametric Anova, Anquan Zhang

Dissertations

The purpose of this dissertation was to empirically investigate the Type I error and power rates of four data transformations that produce a variety of non-normal distributions. Specifically, the transformations investigated were (a) the g-and-h, (b) the generalized lambda distribution (GLD), (c) the power method, and (d) the Burr families of distributions in the context of between-subjects and within-subjects analysis of variance (ANOVA). The traditional parametric F tests and their nonparametric counterparts, the Kruskal-Wallis (KW) and Friedman (FR) tests, were selected to be used in this investigation. The four data transformations produce non-normal distributions that have either valid or invalid …
