Influence Of Tick Transmission On The Host Response To Rickettsial Infection, Soma Chowdhury Jan 2009

Influence Of Tick Transmission On The Host Response To Rickettsial Infection, Soma Chowdhury

LSU Master's Theses

Several members of the spotted fever group (SFG) of Rickettsia are transmitted to the host through infected ixodid (hard) ticks, which can serve as both vectors and reservoirs. Multiple studies have demonstrated that ticks secrete proteins into the bite site of the host that suppress innate and adaptive immune responses. While this suppression of immune responses is beneficial to the tick, it may also be beneficial to the transmitted Rickettsia. We hypothesize that Rickettsia utilize the tick’s ability to alter the host immune response at the tick feeding site to successfully establish infection. In the current study, we analyzed how …

Size Controlled Metal Oxide Nanoparticles:Synthesis, Characterization, And Application To Catalysis, Hongyi Wu Jan 2009

Size Controlled Metal Oxide Nanoparticles:Synthesis, Characterization, And Application To Catalysis, Hongyi Wu

LSU Doctoral Dissertations

The research in this dissertation focuses on the synthesis of size-controlled metal oxide nanoclusters (< 10 nm) on amorphous silica and their catalytic performance in thermal degradation of chlorinated benzenes with regard to the cluster size effect. Furthermore, with the concern that metal can condense as the nano-size nuclei core for particle growth in combustion process, a flow reactor was built to investigate the effect of metal oxide nanoparticles on the formation of soot in fuel-rich combustion. The synthesis of copper oxide nanoclusters was carried by calcination of silica impregnated with dendrimer-metal complexes. The 4th generation poly(propylene imine) dendrimer DAB-Am32 was used in this template-based method. The sizes of copper oxide nanoclusters were exquisitely controlled in the range of 1-5 nm with narrow size distribution by changing the stoichiometric ratio of metal ion to the terminal primary amines of dendrimer, the equivalent metal oxide loading on surface, and the impregnation procedure. XANES and XPS studies revealed that CuO was the dominant component of copper oxide nanoclusters. This method was also experimentally proven to be valid in the preparation of other metal oxide nanoparticles, e.g., Ni and Fe, and with other oxide substrates, e.g., titanium oxide. Chlorinated benzenes were selected as the model compound for studying the activity of metal (Cu and Fe) oxide catalysts with regard to their cluster sizes. Compared to the surrogate of coarse metal oxide samples, which was prepared by incipient wetness method, their nanosize analogues showed superior catalytic activity on the conversion of chlorinated benzenes under both pyrolytic and oxidative thermal condition. Furthermore, such catalytic size effect was also observed on the selectivity of products yields. Sooting combustion was performed using a two-zone flow reactor with precise control on experimental parameters. Gas suspended metal oxide nanoparticles were generated by burning off the organic backbone of the dendrimer-metal complexes in zone 1 and immediately transferred to zone 2, where the hydrocarbon combustion occurred. TEM results of the particulate sample collected at the outlet of reactor indicated that metal oxide nanoparticles promoted soot formation. GC/MS analysis of the extracted organic materials from soot samples suggested the formation of PAH was also promoted by metal addition as well.

Protecting Private Property With Constitutional Judicial Review: A Social Welfare Approach, Daniel H. Cole, Peter Z. Grossman Jan 2009

Protecting Private Property With Constitutional Judicial Review: A Social Welfare Approach, Daniel H. Cole, Peter Z. Grossman

Articles by Maurer Faculty

This article uses a social welfare approach to determine if and when the institution of constitutional judicial review of property regulation and expropriation is efficient. A model is proposed in which property rights protection is a component of social costs. Constitutional judicial review is assumed to either add to or subtract on net from those costs, affecting social welfare generally. It will be shown that under realistic conditions, reflected in real instances, that constitutional judicial review might not enhance economic efficiency or overall social welfare. We show that the efficiency of constitutional judicial review is likely to vary within the …

Investigations Of Chlamydomonas Reinhardtii Ergosterol Biosynthesis, Kristy Marie Brumfield Jan 2009

Investigations Of Chlamydomonas Reinhardtii Ergosterol Biosynthesis, Kristy Marie Brumfield

LSU Doctoral Dissertations

Ergosterol is the major sterol found in the membranes of Chlamydomonas reinhardtii. While past studies have identified some ergosterol mutants in C. reinhardtii, very little is known about sterol biosynthesis pathways in this species. With the elucidation of the Chlamydomonas genome, bioinformatics analysis has allowed us to determine potential genes involved in ergosterol biosynthesis. With this knowledge, a working model of the pathway was designed for future analysis. Several of the ergosterol biosynthetic genes were analyzed in respect to their role and involvement in flagellar regeneration. These genes were upregulated during the regrowth of the flagella. Also Chlamydomonas strains lacking …

Enhancing Reductive Dechlorination Of Chlorinated Ethenes And Ethanes In A Natural Treatment System, Caroline Burda Jan 2009

Enhancing Reductive Dechlorination Of Chlorinated Ethenes And Ethanes In A Natural Treatment System, Caroline Burda

LSU Master's Theses

Chlorinated solvent contamination continues to plague sites around the world. In many cases, lower chlorinated daughter products build up and remain in ground waters and soils. A Bio-Filter/Phytobed (BFP) system has been developed to replace a traditional pump and treat technology currently operating at the ReSolve Superfund site in North Dartmouth, MA. Pilot scale testing at the facility displayed a significant acclimation period prior to microbial dechlorination, as well as delayed degradation of chlorinated ethanes. Microcosm studies suggest that acidic conditions, possibly created by the peat mixture used to construct the bio-filter, inhibited bacterial growth. The neutralization of trench pH …

Particle-Chemical Interactions And Environmental Chemodynamics Of Fine And Ultrafine Particles In A Natural Disaster Scenario, Nicholas A. Ashley Jan 2009

Particle-Chemical Interactions And Environmental Chemodynamics Of Fine And Ultrafine Particles In A Natural Disaster Scenario, Nicholas A. Ashley

LSU Doctoral Dissertations

The interactions of fine and ultrafine particles with chemicals play a dominant role in determining the mobility and availability of pollutants in the environment. Fine particles in sediments can sequester chemicals from the water column, and release volatile and semi-volatile organic compounds to the gas phase upon exposure to air. Ultrafine particles which are photoreactive can degrade these vapor-phase contaminants, and may transform the molecules into species which are more toxic or hazardous than the parent. As the widespread, commercial use of ultrafine particles becomes more common, understanding the chemodynamics of these particles and their interactions with chemicals in the …

Biogenesis Of Iron-Sulfur Clusters And Intracellular Iron Metabolism, Jacob Philip Bitoun Jan 2009

Biogenesis Of Iron-Sulfur Clusters And Intracellular Iron Metabolism, Jacob Philip Bitoun

LSU Doctoral Dissertations

Iron-sulfur ([Fe-S]) clusters represent one of natures most diverse and ubiquitous protein prosthetic groups. [Fe-S] proteins are integral for diverse biological processes. Reconstitution of apo-proteins can occur by exogenously adding excess iron and sulfide. However, due to the toxicity of iron and sulfide, it is most likely that proteins coordinate [Fe-S] cluster assembly in cells. The first part of this dissertation addressed the iron donor for [Fe-S] cluster assembly. Recently, it has been shown that IscA is capable of binding iron with an association constant of 3.0 x 1019M-1. In addition, iron-loaded IscA is capable of …
