Inhibition And Nucleic Acid Binding Studies Of The Carboxyltransferase Component Of Bacterial Acetyl-Coa Carboxylase, Brian Benson Jan 2011

Inhibition And Nucleic Acid Binding Studies Of The Carboxyltransferase Component Of Bacterial Acetyl-Coa Carboxylase, Brian Benson

LSU Doctoral Dissertations

Acetyl-CoA carboxylase is an essential enzyme, as it catalyzes the first committed and regulated step in fatty-acid biosynthesis in all organisms excepting few Archaea and Eubacteria. Acetyl-CoA carboxylase from gram-negative and gram-positive bacteria is a multifunctional enzyme composed of three separate proteins. The carboxyltransferase subunit catalyzes the transfer of a carboxyl group from carboxybiotin to acetyl-CoA, forming malonyl-CoA. The crystal structure of the Escherichia coli (E. coli) carboxyltransferase component of acetyl-CoA carboxylase revealed a unique Zn-domain, presumed to mediate nucleic acid binding, that is absent in the eukaryotic enzyme. Notably, the Zn-domain, adjacent to the active site of carboxyltransferase, makes …

Characterization Of Triggerable Quinones For The Development Of Enzyme-Responsive Liposomes, Maria Fabiana Mendoza Jan 2011

Characterization Of Triggerable Quinones For The Development Of Enzyme-Responsive Liposomes, Maria Fabiana Mendoza

LSU Doctoral Dissertations

For decades, there has been a lot of focus on the development of new carriers for drug delivery applications. From all of the carriers, stimuli-responsive liposomes have been studied extensively, but only a handful have been enzyme-responsive liposomes. Therefore, the field of endogenous proteins as activators of liposomes is a fertile field worthy of exploration. The research described in this dissertation involves how structural changes on the quinone moiety altered their electronic properties, as well as their behavior toward the human enzyme NAD(P)H:quinone oxidoreductase type-1 (hNQO1, over expressed in certain tumor tissues), thus yielding a series of triggerable quinones to …

Role Of Substrate Moisture, Relative Humidity And Temperature On Survival And Foraging Behavior Of Formosan Subterranean Termites, Bal Krishna Gautam Jan 2011

Role Of Substrate Moisture, Relative Humidity And Temperature On Survival And Foraging Behavior Of Formosan Subterranean Termites, Bal Krishna Gautam

LSU Doctoral Dissertations

The Formosan subterranean termite is an important structural pest in the southern United States, especially Louisiana. Baiting systems and spot treatment with non-repellent delayed action termiticides are among the most eco-friendly control approaches. However, to achieve a desired success from these approaches requires a sophisticated knowledge of foraging behavior and food transfer system of these social insects. Moisture and temperature play a vital role in influencing the foraging behavior of these desiccation prone insects. A series of laboratory experiments were conducted to understand the subtleties of foraging behavior of Coptotermes formosanus Shiraki in relation to moisture, relative humidity and temperature. …

Transatlantic Baggage: Expatriate Paris, Modernism, And The Apprenticeship Of Ernest Hemingway, Patrick Blair Bonds Jan 2011

Transatlantic Baggage: Expatriate Paris, Modernism, And The Apprenticeship Of Ernest Hemingway, Patrick Blair Bonds

LSU Doctoral Dissertations

“Transatlantic Baggage: Expatriate Paris, Modernism, and the Apprenticeship of Ernest Hemingway” argues that Hemingway’s expatriation and apprenticeship in modernist Paris from 1921-1925 provided an important impetus for his explorations in gender alterity. The project focuses on a critical-biographical rethinking of Hemingway’s literary development, integrating previous Hemingway biography and gender studies scholarship with new revelations from the manuscript of the forthcoming first two volumes of the Cambridge Edition of the Letters of Ernest Hemingway. An updated study of the author’s literary formation is long overdue; Charles Fenton’s The Apprenticeship of Ernest Hemingway: The Early Years (1954), for example, has served for …

Assessing Social Support In Children: Development And Initial Validation Of The Social Support Questionnaire For Children, Arlene Tayag Gordon

LSU Doctoral Dissertations

Research examining risk and protective factors associated with Posttraumatic Stress Disorder (PTSD) in children has established social support as one of the strongest predictors of psychological health and overall adjustment post-traumatic event (Vigil & Geary, 2008). Greater perceived social support, generally, has been related to more positive outcomes in children (Borja & Callahan, 2008; Cryder, Kilmer, Tedeschi, & Calhoun, 2006; Pina, Villalta, Ortiz, Gottschall, Costa, & Weems, 2008). Understanding the impact of social support on coping with traumatic events such as natural disasters or exposure to community violence is limited by the lack of psychometrically sound measures. The current study …

Structural And Mechanistic Studies On The Interactions Between S-Adenosyl Methionine (Sam) And The Sam-I Riboswitch, Wei Huang Jan 2011

Structural And Mechanistic Studies On The Interactions Between S-Adenosyl Methionine (Sam) And The Sam-I Riboswitch, Wei Huang

LSU Doctoral Dissertations

The chemical and physical properties of RNAs create a diverse functional portfolio to influence the functional outcomes of genomes. One scheme is to recognize cognate small molecule metabolites and to adopt distinct conformations to adjust the gene expression. Segments of messenger RNAs (mRNAs) that adopt this scheme are called riboswitches. As potential targets for designing novel antibiotics and portable regulatory devices for synthetic biology, riboswitches have gained increasing attention. The key to understand the functionality encoded in a riboswitch sequence requires unveiling the mechanism of transmitting ligand recognition to gene expression. In this work, both computational and experimental techniques are …

A General Approach For Vitrification Of Fish Sperm, Rafael Cuevas Uribe Jan 2011

A General Approach For Vitrification Of Fish Sperm, Rafael Cuevas Uribe

LSU Doctoral Dissertations

The goal of this project was to develop streamlined protocols that could be integrated into a standardized approach for vitrification of germplasm for all aquatic species. Vitrification (freezing by formation of “glass” rather than crystalline ice) is simple, fast, inexpensive, can be potentially used to preserve samples in the field, and offers new options for germplasm management especially appropriate for small fishes. Sperm were studied from freshwater fish (channel catfish Ictalurus punctatus), viviparous freshwater fish (green swordtail Xiphophorus hellerii), and marine fishes (spotted seatrout Cynoscion nebulosus, red snapper Lutjanus campechanus, red drum Sciaenops ocellatus, and southern flounder Paralichthys lethostigma).

The Role Of Inflammatory Molecules In Hypertension, Jeffrey Paul Cardinale Jan 2011

The Role Of Inflammatory Molecules In Hypertension, Jeffrey Paul Cardinale

LSU Doctoral Dissertations

Hypertension is a serious condition with high morbidity and mortality rates, as well as a major predisposing factor for multiple cardiovascular and renal diseases. Angiotensin II (Ang II) of the renin-angiotensin system (RAS) plays a pivotal role in propagating the hypertensive response. Moreover, hypertension is considered a chronic low-grade inflammatory condition that intimately involves the actions of proinflammatory cytokines (PICs) such as tumor necrosis factor-alpha (TNF). Recent evidence highlights the role that inflammation, specifically TNF, plays in hypertension and in regulating the RAS, but the understanding as to how inflammation is regulated following Ang II or TNF activation, as well …

The Biological Activity Of Rare Carbohydrates And Cyclitols In Coptotermes Formosanus, Lucas James Veillon

LSU Doctoral Dissertations

In the interest of developing environmentally friendly interventions to infestations by Formosan subterranean termites, Coptotermes formosanus Shiraki, a number of carbohydrates were tested for effects on termites and symbionts. Among these, the D-galactose analog, 2-deoxy-D-galactose, myo-inositol and its fully phosphorylated derivative, phytate, showed promise as potential control chemicals. Feeding bioassays with 20 termite workers, where compounds were applied (concentrations ranged from 160.2-1281.7 µg/mm3) to 5 cm filter paper in water, indicated all three compounds significantly impact termite mortality in a dose dependent fashion over a 2 wk period. Interestingly, when myo-inositol was administered to termites in agar (40 mg/mL), in …

Understanding The Selective Detection Of Homocysteine And Studies Toward The Synthesis Of Vinigrol, Dong Wang Jan 2011

Understanding The Selective Detection Of Homocysteine And Studies Toward The Synthesis Of Vinigrol, Dong Wang

LSU Doctoral Dissertations

The first part of the work is dedicated to the selective detection of Homocysteine (Hcy). In order to better understand this colorimetric detection method, a thermodynamic model for the pH dependence of the effective reduction potential of Hcy derived á-carbon radicals has been proposed. And using viologen indicators of varying reduction potentials, we demonstrate that colorimetric changes occur at experimental pH values consistent with the model. The one-carbon bridge stereochemistry of bicyclo[3.3.1]nonane framework is critical to make the third ring of the tricyclic precursor of vinigrol. We studied this stereochemistry carefully and found that the major diastereomer formed from Robinson …

Comparative Biogeography Of The Arid Lands Of Central Mexico, Jesus Abraham Fernandez Jan 2011

Comparative Biogeography Of The Arid Lands Of Central Mexico, Jesus Abraham Fernandez

LSU Doctoral Dissertations

Most biogeographic studies on the Mexican biota have assumed that the dramatic climate cycles of the Pleistocene epoch and the prominence of the Trans-Mexico Volcanic Belt have played major roles in the origin and diversification of species. Here the pylogenetics and biogeography of four codistributed rodent species were studied. In each case, a phylogenetic hypothesis for the taxon and allied species using two mitochondrial (Cytochrome-b and 12S), and two nuclear genes (GHR and IRBP) was generated, appropriate taxonomic changes were recommended, and a temporal framework was generated to identify events that may have produced the phylogenetic pattern. Nelson’s woodrat Neotoma …

Arbovirus Phenotype Alters Transmission Potential, Rebecca C. Christofferson Jan 2011

Arbovirus Phenotype Alters Transmission Potential, Rebecca C. Christofferson

LSU Doctoral Dissertations

Extrinsic and environmental factors are known to affect the transmission of arthropod-borne viruses (arboviruses), including variations in the arthropod vector populations. Differences among these factors have been associated with differential transmission and are sometimes used to control the spread of an arbovirus through a vertebrate population in an effort to prevent or disrupt an outbreak. However, diversity in intrinsic viral populations, such as genetic and phenotypic variability, is not often accounted for when considering alterations in transmission. Presented in this dissertation are four experimental studies that explore the contribution of viral intrinsic factors, especially phenotypic variability, to the transmission potential …
