The Dialogism Of Self And Other In Contemporary American Drama, Shih-Yi Huang Jan 2010

The Dialogism Of Self And Other In Contemporary American Drama, Shih-Yi Huang

LSU Doctoral Dissertations

This work is interdisciplinary in orientation and brings together American theatre (and culture) and contemporary ethical philosophy. I am introducing the French philosopher Emmanuel Lévinas and his theory of Self and Other to an analysis of contemporary American drama—a mode of approach that is new to the discipline of theatre studies. Lévinas’s insights are particularly relevant to the concerns of the 21st century and how we might rethink relationships and values. My work looks at contemporary American plays in terms of nationalism, gender politics, racial dynamics and ecological issues. I contend that these playwrights are attempting to go beyond conventional …

Connections Between Individual Dispersal Behavior And The Multi-Scale Distribution Of A Saproxylic Beetle, Heather Bird Jackson Jan 2010

Connections Between Individual Dispersal Behavior And The Multi-Scale Distribution Of A Saproxylic Beetle, Heather Bird Jackson

LSU Doctoral Dissertations

Species incidence results from a complex interaction among species traits (e.g., mobility and behavior), intra- and inter-specific interactions, quality and configuration of the landscape, and historical events. Determining which factors are most important to incidence is difficult because the multiple processes affecting incidence operate at different temporal and spatial scales. I conducted an empirically-based study relating individual behavior (dispersal, habitat selection, and intra-specific interactions) with hierarchically-organized environmental filters to predict the incidence of Odontotaenius disjunctus (Passalidae), a saproxylic (=decayed wood dependent) beetle common to eastern North American forests, at multiple spatial scales. In dispersal experiments, O. disjunctus movement was faster …

Genetic And Cytological Investigation Of Nucleostemin-1 In Drosophila Melanogaster, Raphyel Ojomo Rosby Jan 2010

Genetic And Cytological Investigation Of Nucleostemin-1 In Drosophila Melanogaster, Raphyel Ojomo Rosby

LSU Doctoral Dissertations

Mammalian nucleostemin (NS) is a nucleolar GTP-binding protein implicated in cell cycle progression, stem cell proliferation, and ribosome assembly. Drosophila melanogaster contains a four-member nucleostemin family (NS1-4). Nucleostemin 1 (NS1) is the closest orthologue to human NS; it shares 33% identity and 67% similarity with human NS. We show that NS1 has intrinsic GTPase and ATPase activity, and that it is present within nucleoli of most larval and adult cells. Endogenous NS1 and lightly expressed GFP-NS1 enrich within the nucleolar granular regions as expected, while over-expressed GFP-NS1 localizes throughout the nucleolus and nucleoplasm, and to several transcriptionally active inter-bands of …

A Four-Cysteine Zinc Finger In Carboxyltransferase Structurally Links The Functions Of Enzymatic Activity And Negative Feedback Regulation Of Translation, Glen D. Meades Jan 2010

A Four-Cysteine Zinc Finger In Carboxyltransferase Structurally Links The Functions Of Enzymatic Activity And Negative Feedback Regulation Of Translation, Glen D. Meades

LSU Doctoral Dissertations

Acetyl-CoA carboxylase is the first and committed step of de novo fatty acid synthesis in all organisms. In Escherichia coli, the enzyme is expressed as separate proteins for the three functional components: a biotin carboxylase, a biotin carboxyl carrier protein, and a carboxyltransferase. The carboxyltransferase enzyme has an α2β2 heterotetrameric quaternary arrangement. The crystal structure of the β subunit revealed a zinc-binding domain, a feature common among nucleic acid-binding proteins. Carboxyltransferase preferentially binds mRNA coding for its two subunits over other nucleic acids, suggesting a means by which the enzyme can regulate its own expression. In the first study, the …

Modulation Of Cholinergic Signaling In Embryonic Zebrafish: Anatomical And Behavioral Consequences, Evdokia Menelaou Jan 2010

Modulation Of Cholinergic Signaling In Embryonic Zebrafish: Anatomical And Behavioral Consequences, Evdokia Menelaou

LSU Doctoral Dissertations

Smoking during pregnancy remains a major health concern in the United States. Nicotine is one of the main ingredients of cigarettes and a neurotoxicant which has been purported to affect many aspects of nervous system development causing long-term abnormalities in the offspring. We took advantage of the zebrafish model to investigate the effects of nicotine in nervous system anatomy and function. It was previously reported that embryonic nicotine exposure causes pathfinding errors in secondary motoneuron (SMN) axons through the activation of nicotine acetylcholine receptors (nAChRs). However, the nicotine-induced effects on SMN pathfinding coincided with muscle degeneration. We hypothesized that nicotine …

Embyronic Nicotine Exposure And Its Impact On Spinal Neuron Development In Zebrafish, Latoya Telameca Paul Jan 2010

Embyronic Nicotine Exposure And Its Impact On Spinal Neuron Development In Zebrafish, Latoya Telameca Paul

LSU Doctoral Dissertations

Nicotine, a drug of abuse, has been shown to have deleterious outcomes on nervous system development in vertebrates. Using zebrafish behavior as a diagnostic tool, we aimed to understand the effects of embryonic nicotine exposure on spinal neuron development. We initially quantified nicotine incorporation into zebrafish embryos. We found that only a fraction of the waterborne concentration of nicotine was incorporated into embryos. Also, when embryos were exposed to epibatidine and ABT 418, potent alpha 4/beta 2 nAChRs agonists, the embryos exhibited a robust swim-like behavioral response similar to that of nicotine. We then performed immunohistochemistry utilizing the mAB290 antibody …

1337 W4yz Of {Dollar}P34king: Toward A Unifying Pragmatic Theory Of Virtual Speech Community Building, Tracy Rene Leblanc Jan 2010

1337 W4yz Of {Dollar}P34king: Toward A Unifying Pragmatic Theory Of Virtual Speech Community Building, Tracy Rene Leblanc

LSU Doctoral Dissertations

Building a speech community requires building a shared history of communicative interaction. Within a virtual medium, speech community members employ accommodations for the lack of shared physical space that face-to-face interactions provide. These accommodations, amassing through extended discourse, bring to light the communicative strategies that virtual interlocutors employ in order to build community. Drawing from a corpus of unscripted, naturally occurring discourse of a particular virtual speech community, I engage three frames of linguistic analysis in order to recognize the communicative strategies that constitute speech community building. Relevance Theory (Sperber and Wilson 1995) accounts for the individual cognitive work involved …

Revealing The Role Of Receptor Wsx1: A Double-Edged Sword In Tumor Progession, Denada Dibra Jan 2010

Revealing The Role Of Receptor Wsx1: A Double-Edged Sword In Tumor Progession, Denada Dibra

LSU Doctoral Dissertations

Tumor initiation and progression are dependent on both aberrant gene expression in tumor cells and the communication between tumor cells and its micro- and systemic microenvironment. Many tumor suppressor genes and oncogenes have been characterized to suppress or promote tumor growth, but fewer genes in tumors are well-characterized as interacting with immune cells in the host to promote or inhibit tumor growth. The interleukin (IL) 27 receptor WSX1 is expressed in immune cells and induces an IL27-dependent immune response. Opposing this conventional dogma, our initial results reveal a much higher level of WSX1 expression in multiple types of epithelial tumor …

Staging Polemics: Charles Palissot, Voltaire, And The "Theatrical Event" In Eighteenth-Century France, Logan James Connors Jan 2010

Staging Polemics: Charles Palissot, Voltaire, And The "Theatrical Event" In Eighteenth-Century France, Logan James Connors

LSU Doctoral Dissertations

This dissertation explores the exciting world of eighteenth-century French dramatic writing, performance and criticism from the point of view of the theatrical spectator. Instead of focusing on one single genre or writer, I assemble the textual creation, performance, and criticism of certain “polemical” plays into what I term a “theatrical event.” This optic provides a holistic vision of theater and an accurate view of how drama underwent noticeable change due to playwrights’ political associations, public reactions to performance, and the emerging power of the periodical press. In sum, this project differs from previous studies by focusing on the increasing rhetorical …

Reading Out Of Doors: How Nature Becomes Text And Vice-Versa, Richmond Minor Eustis Jan 2010

Reading Out Of Doors: How Nature Becomes Text And Vice-Versa, Richmond Minor Eustis

LSU Doctoral Dissertations

The tensions between city and country, the artificial and the natural, the real and the fake are at the heart of attempts to render nature in writing. In many such texts, nature—especially wilderness—is the realm of the real, authentic, and pure, while the city is the realm of the artificial and corrupt. This placement of value in nature, members of the critical theory camp tend to counter, is misguided. Any effort to render nature in text is by its “nature” artificial—far more about human values embedded in language itself than about some extra-textual world. With an approach derived from theorists …

Near-Infrared Fluorescent Nanogumbos For Biomedical Imaging, David K. Bwambok, Bilal El-Zahab, Santhosh K. Challa, Min Li, Lin Chandler, Gary A. Baker, Isiah M. Warner

Faculty Publications

Herein, we report on near-infrared (NIR) fluorescent nanoparticles generated from an emergent class of materials we refer to as a Group of Uniform Materials Based on Organic Salts (GUMBOS). GUMBOS are largely frozen ionic liquids, although the concept is more general and is also easily applied to solid ionic materials with melting points in excess of 100 °C. Nanoparticles based on GUMBOS (nanoGUMBOS) derived from a NIR fluorophore are prepared using a reprecipitation method and evaluated for in vivo fluorescence imaging. Due to their uniformity, single-step preparation, and composite nature, nanoGUMBOS help to resolve issues with dye leakage problems innate …

Phylogeny Of The Macaques (Cercopithecidae: Macaca) Based On Alu Elements, Jing Li, Kyudong Han, Jinchuan Xing, Heui Soo Kim, Jeffrey Rogers, Oliver A. Ryder, Todd Disotell, Bisong Yue, Mark A. Batzer Dec 2009

Phylogeny Of The Macaques (Cercopithecidae: Macaca) Based On Alu Elements, Jing Li, Kyudong Han, Jinchuan Xing, Heui Soo Kim, Jeffrey Rogers, Oliver A. Ryder, Todd Disotell, Bisong Yue, Mark A. Batzer

Faculty Publications

Genus Macaca (Cercopithecidae: Papionini) is one of the most successful primate radiations. Despite previous studies on morphology and mitochondrial DNA analysis, a number of issues regarding the details of macaque evolution remain unsolved. Alu elements are a class of non-autonomous retroposons belonging to short interspersed elements that are specific to the primate lineage. Because retroposon insertions show very little homoplasy, and because the ancestral state (absence of the SINE) is known, Alu elements are useful genetic markers and have been utilized for analyzing primate phylogenentic relationships and human population genetic relationships. Using PCR display methodology, 298 new Alu insertions have …

Yy1'S Dna-Binding Motifs In Mammalian Olfactory Receptor Genes, Christopher D. Faulk, Joomyeong Kim Dec 2009

Yy1'S Dna-Binding Motifs In Mammalian Olfactory Receptor Genes, Christopher D. Faulk, Joomyeong Kim

Faculty Publications

Background: YY1 is an epigenetic regulator for a large number of mammalian genes. While performing genome-wide YY1 binding motif searches, we discovered that the olfactory receptor (OLFR) genes have an unusual cluster of YY1 binding sites within their coding regions. The statistical significance of this observation was further analyzed. Results: About 45% of the olfactory genes in the mouse have a range of 4-8 YY1 binding sites within their respective 1 kb coding regions. Statistical analyses indicate that this enrichment of YY1 motifs has likely been driven by unknown selection pressures at the DNA level, but not serendipitously by some …

Sphingosine-1-Phosphate Elicits Receptor-Dependent Calcium Signaling In Retinal Amacrine Cells, Scott Crousillac, Jeremy Colonna, Emily Mcmains, Jill Sayes Dewey, Evanna Gleason Dec 2009

Sphingosine-1-Phosphate Elicits Receptor-Dependent Calcium Signaling In Retinal Amacrine Cells, Scott Crousillac, Jeremy Colonna, Emily Mcmains, Jill Sayes Dewey, Evanna Gleason

Faculty Publications

Evidence is emerging indicating that sphingosine-1-phosphate (S1P) participates in signaling in the retina. To determine whether S1P might be involved in signaling in the inner retina specifically, we examine the effects of this sphingolipid on cultured retinal amacrine cells. Whole cell voltage-clamp recordings reveal that S1P activates a cation current that is dependent on signaling through Gi and phospholipase C. These observations are consistent with the involvement of members of the S1P receptor family of G-protein-coupled receptors in the production of the current. Immunocytochemistry and PCR amplification provide evidence for the expression of S1P1R and S1P3R in amacrine cells. The …

The Amino Terminus Of Herpes Simplex Virus Type 1 Glycoprotein K (Gk) Modulates Gb-Mediated Virus-Induced Cell Fusion And Virion Egress, Vladimir N. Chouljenko, Arun V. Iyer, Sona Chowdhury, Dmitry V. Chouljenko, Konstantin G. Kousoulas Dec 2009

The Amino Terminus Of Herpes Simplex Virus Type 1 Glycoprotein K (Gk) Modulates Gb-Mediated Virus-Induced Cell Fusion And Virion Egress, Vladimir N. Chouljenko, Arun V. Iyer, Sona Chowdhury, Dmitry V. Chouljenko, Konstantin G. Kousoulas

Faculty Publications

Herpes simplex virus type 1 (HSV-1)-induced cell fusion is mediated by viral glycoproteins and other membrane proteins expressed on infected cell surfaces. Certain mutations in the carboxyl terminus of HSV-1 glycoprotein B (gB) and in the amino terminus of gK cause extensive virus-induced cell fusion. Although gB is known to be a fusogenic glycoprotein, the mechanism by which gK is involved in virus-induced cell fusion remains elusive. To delineate the amino-terminal domains of gK involved in virus-induced cell fusion, the recombinant viruses gKΔ31-47, gKΔ31-68, and gKΔ31-117, expressing gK carrying in-frame deletions spanning the amino terminus of gK immediately after the …

How Do Animal Mitochondria Tolerate Water Stress?, Michael A. Menze, Steven C. Hand Dec 2009

How Do Animal Mitochondria Tolerate Water Stress?, Michael A. Menze, Steven C. Hand

Faculty Publications

The vast majority of animal species do not tolerate severe water stress, but the encysted embryo of the brine shrimp Artemia franciscana is an exceptionally useful organism to investigate physiological mechanisms for enduring extreme environmental insults. Any substantial reduction in cellular water poses a threat to survival. Nevertheless anhydrobiotic animals survive virtually complete loss of cellular water. The mechanisms that govern " life without water" (anhydrobiosis) are still not well understood. With certain exceptions, it seems that a recurring strategy for tolerating severe water loss involves the accumulation of both low molecular weight solutes (e.g., trehalose or other polyol) and …

Impact Of Reproductive Effort On Survival Of Rio Grande Wild Turkey Meleagris Gallop Intermedia Hens In Texas, Bret A. Collier, Kyle B. Melton, Jason B. Hardin, Nova J. Silvy, Markus J. Peterson Dec 2009

Impact Of Reproductive Effort On Survival Of Rio Grande Wild Turkey Meleagris Gallop Intermedia Hens In Texas, Bret A. Collier, Kyle B. Melton, Jason B. Hardin, Nova J. Silvy, Markus J. Peterson

Faculty Publications

The southeastern portion of the Edwards Plateau of Texas, historically a stronghold of Rio Grande wild turkeys Meleagris gallopavo intermedia, has seen the numbers of turkeys declining since the 1970s. Because hen survival is a key parameter affecting turkey population dynamics, we monitored radio-tagged Rio Grande wild turkey hens on the Edwards Plateau during 2001-2007 to compare survival during the breeding season in areas where turkey abundance has declined vs areas with stable populations. Breeding season survival was best predicted by a model that allowed variation during different periods of the reproductive season (initial nesting during 25 March 21 April, …

Though cryopreservation of mouse sperm yields good survival and motility after thawing, cryopreservation of rat sperm remains a challenge. This study was designed to evaluate the biophysics (membrane permeability) of rat in comparison to mouse to better understand the cooling rate response that contributes to cryopreservation success or failure in these two sperm types. In order to extract subzero membrane hydraulic permeability in the presence of ice, a differential scanning calorimeter (DSC) method was used. By analyzing rat and mouse sperm frozen at 5°C/min and 20°C/min, heat release signatures characteristic of each sperm type were obtained and correlated to cellular …

Comparative Acute Toxicity Of Neonicotinoid And Pyrethroid Insecticides To Non-Target Crayfish (Procambarus Clarkii) Associated With Rice-Crayfish Crop Rotations, Gary C. Barbee, Michael J. Stout Nov 2009

Comparative Acute Toxicity Of Neonicotinoid And Pyrethroid Insecticides To Non-Target Crayfish (Procambarus Clarkii) Associated With Rice-Crayfish Crop Rotations, Gary C. Barbee, Michael J. Stout

Faculty Publications

Background: Most insecticides used to control rice water weevil (Lissorhoptrus oryzophilus Kuscel) infestations are pyrethroids. However, pyrethroids are highly toxic to non-target crayfish associated with rice-crayfish crop rotations. One solution to the near-exclusive reliance on pyrethroids in a rice-crayfish pest management program is to incorporate neonicotinoid insecticides, which are insect specific and effective against weevils but not extremely toxic to crayfish. This study aimed to take the first step to assess neonicotinoids as alternatives to pyrethroids in rice-crayfish crop rotations by measuring the acute toxicities of three candidate neonicotinoid insecticides, clothianidin, dinotefuran and thiamethoxam, to juvenile Procambarus clarkii (Girard) crayfish …

Edwardsiella Ictaluri Encodes An Acid-Activated Urease That Is Required For Intracellular Replication In Channel Catfish (Ictalurus Punctatus) Macrophages, Natha J. Booth, Judith B. Beekman, Ronald L. Thune

Faculty Publications

Genomic analysis indicated that Edwardsiella ictaluri encodes a putative urease pathogenicity island containing the products of nine open reading frames, including urea and ammonium transporters. In vitro studies with wild-type E. ictaluri and a ureG::kan urease mutant strain indicated that E. ictaluri is significantly tolerant of acid conditions (pH 3.0) but that urease activity is not required for acid tolerance. Growth studies demonstrated that E. ictaluri is unable to grow at pH 5 in the absence of urea but is able to elevate the environmental pH from pH 5 to pH 7 and grow when exogenous urea is available.

Actin-related protein 5 (ARP5) is a conserved subunit of the INO80 chromatin-remodeling complex in yeast and mammals. We have characterized the expression and subcellular distribution of Arabidopsis thaliana ARP5 and explored its role in the epigenetic control of multicellular development and DNA repair. ARP5-specific monoclonal antibodies localized ARP5 protein to the nucleoplasm of interphase cells in Arabidopsis and Nicotiana tabacum. ARP5 promoter-reporter fusions and the ARP5 protein are ubiquitously expressed. A null mutant and a severe knockdown allele produced moderately dwarfed plants with all organs smaller than the wild type. The small and slightly deformed organs such as leaves and …

Transposable elements (TEs) are an important source of genome diversity and play a crucial role in genome evolution. A recent study by Zhao et al. describes novel patterns of TE diversification in the genome of the extinct mammoth Mammuthus primigenius. Analysis of Mammuthus has provided a unique genome landscape, a pivotal species for understanding TEs and genome evolution and hints at the diversity we verge on discovering by expanding our taxonomic sampling among genomes. Strategies based on this work might also revolutionize investigations of the interface between TE dynamics and genome diversity. © 2009 Elsevier Ltd. All rights reserved.

Timing Of Migration And Patterns Of Winter Settlement By Henslow's Sparrows, Erik I. Johnson, Jennifer K. Dimiceli, Philip C. Stouffer Nov 2009

Timing Of Migration And Patterns Of Winter Settlement By Henslow's Sparrows, Erik I. Johnson, Jennifer K. Dimiceli, Philip C. Stouffer

Faculty Publications

Fall arrival is an important period in the life history of migratory birds because processes during this period determine where birds spend the winter, which is linked to subsequent survival and condition at the time of spring migration. Henslow's Sparrows (Ammodramus henslowii) winter in savannas of longleaf pine (Pinus palustris), but their secretive behavior limits our knowledge of their winter ecology, including behavioral processes that lead to their documented preference of an ephemeral habitat-recently burned savannas. We expected that upon arrival Henslow's Sparrows actively seek out recently burned savannas and that their over-winter location is dependent on intraspecific interactions during …
