Characterization Of Equine Pulmonary Endothelin Receptors In Health And Disease, Sumanth Polikepahad Jan 2006

Characterization Of Equine Pulmonary Endothelin Receptors In Health And Disease, Sumanth Polikepahad

LSU Doctoral Dissertations

Endothelin-1 (ET-1) has been implicated in allergic type of respiratory inflammatory diseases in various species of animals including horses. This peptide elicits its actions by acting through endothelin-A (ET-A) and endothelin-B (ET-B) receptor sub-types. In this project, we have hypothesized that endothelin receptors (both ET-A and ET-B) are altered in terms of affinity and expression, in the lungs of summer pasture-associated obstructive pulmonary disease (SPAOPD)-affected horses. Objective of this dissertation was to determine the alterations in the affinity and expression of endothelin receptors in the lungs of healthy and SPAOPD-affected horses. To pursue our hypothesis, we have employed pharmacological, immunohistochemical …

A Neural Network Model For Classification Of Coastal Wetlands Vegetation Structure With Moderate Resolution Imaging Spectro-Radiometer (Modis) Data, Evaristo Joseph Liwa Jan 2006

A Neural Network Model For Classification Of Coastal Wetlands Vegetation Structure With Moderate Resolution Imaging Spectro-Radiometer (Modis) Data, Evaristo Joseph Liwa

LSU Doctoral Dissertations

Mapping coastal marshes is an important component in the management of coastal environments. Classification of marshes using remote sensing data has traditionally been performed by employing either parametric supervised classification algorithms or unsupervised classification algorithms. The implementation of these conversional classification methods is based on the underlying distributions concerning the probability density functions (PDF). Neural networks provide a practical approach to this classification because they are essentially non-parametric data transformations that are not restricted by any underlying assumptions. The major objective of this study was to evaluate the ability of neural networks using Moderate Resolution Imaging Spectro-radiometer (MODIS) data to …

Ecology Of Lesser Scaup Amphipods In The Upper-Midwest: Scope And Mechanisms Of The Spring Condition Hypothesis And Implications For Migration Habitat Conservation, Michael Jason Anteau Jan 2006

Ecology Of Lesser Scaup Amphipods In The Upper-Midwest: Scope And Mechanisms Of The Spring Condition Hypothesis And Implications For Migration Habitat Conservation, Michael Jason Anteau

LSU Doctoral Dissertations

I tested the scope of the Spring Condition Hypothesis in explaining the continental population decline of lesser scaup (Aythya affinis; hereafter scaup) and explored potential mechanisms affecting female body condition to assist conservation efforts for population recovery. Lipid reserves of females currently are lower than historical values during spring migration throughout Iowa, Minnesota, and North Dakota; females catabolized lipids throughout this area (indexed by concentrations of plasma-lipid metabolites, which accounted for 75% of the variation in mass change). My results indicate that a large segment of the continental scaup population likely is affected by decreased lipid reserves, which could cause …

Biomechanical Characteristics Of Low Back Tissues During Trunk Flexion-Extension, Michael William Olson Jan 2006

Biomechanical Characteristics Of Low Back Tissues During Trunk Flexion-Extension, Michael William Olson

LSU Doctoral Dissertations

Analysis of the mechanical and neural regulatory mechanisms of the flexion-relaxation phenomenon (FRP), observed in deep trunk flexion, was performed since it is believed these mechanisms provide insight into the causes of low back injury and pain. Three methods were used to analyze the behavior of the lumbar tissues during trunk flexion-extension exercises: 1) active continuous cyclic movement, 2) acute cyclic movement at different orientations, and 3) passive continuous cyclic movement. All activities were performed at a rate of 0.1 Hz (6 cycles•min-1) while monitoring the surface electromyography (EMG) of the lumbar paraspinal muscles. Abdominal, hamstring, and quadriceps muscle activities …

The Regulation Of Genes Involved In Trichome Development, Matthew Lloyd Brown Jan 2006

The Regulation Of Genes Involved In Trichome Development, Matthew Lloyd Brown

LSU Doctoral Dissertations

Arabidopsis thaliana is an organism that can be used as a model for most of the processes that occur in flowering plants. The leaf hairs, or trichomes, of Arabidopsis thaliana are macroscopic single cells that have been used as a model system for cell fate determination, cell expansion, cell cycle regulation, cell wall deposition, as well as other processes. Initiation of the trichome cell fate is controlled by a complex of genes including GLABRA1 (GL1), TRANSPARENT TESTA GLABRA (TTG), and GLABRA3 (GL3). This work examines the role of GL3 in trichome initiation and uses plants expressing varying levels of GL3 …

Power Analysis For A Mixed Effects Logistic Regression Model, Yinmei Li Jan 2006

Power Analysis For A Mixed Effects Logistic Regression Model, Yinmei Li

LSU Doctoral Dissertations

In herd health studies, the mixed effects logistic regression model with random herd effects are commonly used for modeling clustered binary data. These models are well developed and widely used in the literature, among which is the logistic-normal regression model. In contrast to the rich literature in modeling methods, the sample size/power analysis methods for such mixed effects models are sparse. The sample size/power analysis method for the logistic-normal regression model is not readily available. This study is to develop a power analysis/sample size estimation method for the logistic-normal regression model. Extended from the sample size method for the likelihood …

The Scent Of A New World Novel: Translating The Olfactory Language Of Faulkner And García Márquez, Terri Smith Ruckel Jan 2006

The Scent Of A New World Novel: Translating The Olfactory Language Of Faulkner And García Márquez, Terri Smith Ruckel

LSU Doctoral Dissertations

Both William Faulkner and Gabriel García Márquez introduce the olfactory as a focal element in their writing, producing works that challenge the singular primacy of sight as the unrivaled means by which the New World might be understood. As they translate experiences of the New World into language, both writers record the power of olfactory perception to reflect memory and history, to shape identity, to mark unmistakably certain crisis moments of ethical action, and to delineate a form of knowledge crucial to their New World poetics of the novel. Observing and analyzing the olfactory language particular to the cultural spaces …

Direct Detection Of Homocysteine And Syntheses Of Lanthanide Complexes As Biosensors, Weihua Wang Jan 2006

Direct Detection Of Homocysteine And Syntheses Of Lanthanide Complexes As Biosensors, Weihua Wang

LSU Doctoral Dissertations

At elevated levels, homocysteine (Hcy) is a risk factor for cardiovascular diseases and Alzheimer’s disease. It’s also implicated in a number of other diseases such as neural tube defects, pregnancy complications, and renal failures. The monitoring of Hcy levels in plasma is of current concern. To date, the biochemical mechanism by which Hcy is involved in disease states is unclear. Herein, we describe highly selective colorimetric methods for the direct determination of Hcy. Inexpensive, commercially available materials are reported. The results show potential application for the detection of Hcy in human blood plasma. Additionally, new HPLC postcolumn detection methods for …

Modeling The Effects Of Endocrine Disrupting Chemicals On Atlantic Croaker: Understanding Biomarkers And Predicting Population Responses, Cheryl Anne Murphy Jan 2006

Modeling The Effects Of Endocrine Disrupting Chemicals On Atlantic Croaker: Understanding Biomarkers And Predicting Population Responses, Cheryl Anne Murphy

LSU Doctoral Dissertations

A number of environmental stressors have been shown to interfere with reproductive and behavioral processes of fish by interfering with endocrine function. Most biomarkers of endocrine disturbance tend to be static measurements from dynamic systems making them difficult to evaluate within the context of an individual, or subtle effects that do not relate well to endpoints of ecological significance. I present an approach that uses a series of models, based on Atlantic croaker, to extrapolate laboratory results to indicators of individual and population health. First, I created a physiologically based model that simulates vitellogenesis in a female fish. The model …

Repression And Reduction: The Apparatchik's Discourse In The Works Of Ammianus Marcellinus, Denis Diderot, Victor Serge And George Orwell, Jason Paul Juneau Jan 2006

Repression And Reduction: The Apparatchik's Discourse In The Works Of Ammianus Marcellinus, Denis Diderot, Victor Serge And George Orwell, Jason Paul Juneau

LSU Doctoral Dissertations

In monopolizing political power, the state claims to possess the best idea towards leading a society and solving its problems. While these claims may vary according to regime, all face the eventual failure of expectation on the part of its subjects. No regime can master all the variables in running the country, and so it must convince their subjects otherwise of its legitimacy, despite the reality of their failure. The apparatchik’s discourse is the interaction of the state’s discourse and that of its institutions. This discourse is used to uphold the state’s legitimacy through the expertise of its institutions. The …

Assessing The Potential Impact Of Microbes In The Edwards And Trinity Aquifers Of Central Texas, Kelli Willson Randall Jan 2006

Assessing The Potential Impact Of Microbes In The Edwards And Trinity Aquifers Of Central Texas, Kelli Willson Randall

LSU Master's Theses

The Edwards Aquifer in central Texas is one of the largest carbonate aquifers in the United States, supplying nearly two million people with water. The role of microorganisms in the development of deep carbonate aquifers has not been thoroughly investigated. The Edwards Aquifer is composed of a freshwater zone and a sulfidic, saline water zone. Down-well video surveys show an abundance of white filamentous and planktonic biomass floating in the water column, indicating that the saline water may serve as a habitat for microbes and provide a unique opportunity to investigate microbially enhanced deep subsurface karstification. A combination of geochemical …

The Effect Of A Condensed Tannin Containing Forage, Sericea Lespedeza On Existing And Challenge Infections Of Haemonchus Contortus In Sheep, Leigh Ann Chafton Jan 2006

The Effect Of A Condensed Tannin Containing Forage, Sericea Lespedeza On Existing And Challenge Infections Of Haemonchus Contortus In Sheep, Leigh Ann Chafton

LSU Master's Theses

Haemonchus contortus is one of the most threatening parasites to small ruminant production. Control has traditionally relied on the use of anthelmintics. Control has waned because the worm population has developed resistance to most of the currently available anthelmintics and alternative control measures are needed. Current consumer pressure is to reduce the use of chemicals in agricultural products, thus pushing control methods to more natural and acceptable approaches. One such approach is the feeding of condensed tannin containing forages either as fresh forage or dried products (hay, meal, pellets, etc). This study was conducted to determine the effect of a …

Study Of Reliable Data Communication In Wireless Sensor Networks, Ravilochan Shamanna Jan 2006

Study Of Reliable Data Communication In Wireless Sensor Networks, Ravilochan Shamanna

LSU Master's Theses

A distributed wireless sensor network consists of numerous tiny autonomous sensing nodes deployed across a wide geographical area. These sensor nodes self organize and establish radio communication links with the neighboring nodes to form multi-hop routing paths to the central base station. The dynamic and lossy nature of wireless communication poses several challenges in reliable transfer of data from the sensor nodes to the sink. There are several applications of sensor networks wherein the data collected by the sensors in the network are critical and hence have to be reliably transported to the sink. An example of such an application …

Measuring Player Perceptions Of Advertising In Online Games, Ben Lewis Jan 2006

Measuring Player Perceptions Of Advertising In Online Games, Ben Lewis

LSU Master's Theses

An experiment with 100 participants aged 18-24 was conducted to measure the effects of advertising in an online role-playing computer game on perceived interactivity and other aspects of gameplay experience. Results from a post-test questionnaire revealed insight into players' attitudes toward advertising in video game environments, and reflected varying levels of advertising awareness and recall, message recognition, and factors in purchasing habits. Results suggested that while advertising in online games can sometimes trigger high advertising awareness rates, it can also reduce a game's perceived sense of realism and genuinely annoy players if not appropriately coordinated with the game environment. Whereas …

Animation In Artificial Grammar Learning: Can Animation Facilitate Learning?, Bill Sallas Jan 2006

Animation In Artificial Grammar Learning: Can Animation Facilitate Learning?, Bill Sallas

LSU Master's Theses

Domangue, Mathews, Sun, Roussel, and Guidry (2004) trained participants to generate valid exemplars from an artificial grammar using either memory-based or model-based processing. Their results showed that learning by memory-based processing resulted in fast but inaccurate performance, while model-based learning resulted in slow but accurate performance. Attempts to integrate both types of training did not result in fast and accurate string generation. Fast and accurate performance was achieved by Sun and Mathews (2004) using a computer animated display to train participants. The current study used a 2x2x2 factorial design to determine why participants who view an animated display of a …

Evaluating Miriam Solomon's Social Empiricism: The Environmental Endocrine Hypothesis, Robby Joseph Burleigh Jan 2006

Evaluating Miriam Solomon's Social Empiricism: The Environmental Endocrine Hypothesis, Robby Joseph Burleigh

LSU Master's Theses

Throughout the history of science, philosophers and scientists alike have sought to codify a set of rules that would guarantee those who practice science success. These rules, if followed faithfully, would eliminate the guesswork from science, and instead, mold the practice of science into a rule - governed enterprise. Many philosophers of science have attempted to generate the rules that would govern successful scientific practice; however, with no success. Miriam Solomon attempts to give scientists heuristic advice by using a naturalistic approach in which she uses various case studies throughout the history of science to illustrate her approach. The core …

Control Of Listeria Species And Other Bacteria In Crawfish And Crab Processing Facilities, Utilizing Copper Drains, Coatings And Concrete, Containing Copper Ions, Artem S. Rogovskyy

LSU Master's Theses

The antibacterial properties of copper ions against Listeria spp., Pseudomonas spp., Escherichia coli and other coliforms, and total aerobic bacteria have been investigated in seafood processing environments. Our hypothesis was that drains fabricated from copper and coatings and concrete containing copper ions that have been used for sealing floors and walls could be utilized in crawfish and crab processing facilities as an effective means of controlling Listeria spp. and other unwanted bacteria. Copper in the form of copper sulfate pentahydrate was incorporated into coatings and concrete at the salt concentration of 25 ppm (6.36 ppm Cu++). Sampling sites were selected …

Aristotelian-Liberal Autonomy, Geoffrey Allan Plauche Jan 2006

Aristotelian-Liberal Autonomy, Geoffrey Allan Plauche

LSU Master's Theses

Written in the burgeoning tradition of Aristotelian liberalism, my thesis seeks to enrich this tradition by developing a liberal theory of autonomy based on a broadly Aristotelian foundation. Chapter One summarizes and critiques the major contemporary theories of autonomy developed by Kant and analytic philosophers. Chapter Two explicates the Aristotelian conception of autonomy, drawing on recent work by Fred Miller and Roderick Long. Aristotle is chided for not being liberal enough and so Chapter Three develops an Aristotelian-liberal theory of autonomy based in part on recent work by Douglas Rasmussen, Douglas Den Uyl and Roderick Long. Global and local individual …

Brugia Phangi: Effects Of Third Stage Larvae Es Immunization On Early Migration And Parasite Establishment In Mongolian Gerbils (Meriones Unguiculatus), Ginger Ann Robertson Jan 2006

Brugia Phangi: Effects Of Third Stage Larvae Es Immunization On Early Migration And Parasite Establishment In Mongolian Gerbils (Meriones Unguiculatus), Ginger Ann Robertson

LSU Master's Theses

Brugia infections occur via the bite of an infected mosquito. Third stage infective larvae (L3) deposited on the skin during feeding migrate into the bite wound, through skin and into the lymphatic system. It is hypothesized that L3 excretory/secretory products (ES) are important in this initial phase of the infection. A model for these early migrations has been established by inoculating L3s into the dermis (ID) of the permissive gerbil host. In this model, most L3s injected ID in the louer hind limb travel to the popliteal lymph node by 3 days post infection. Adult parasites are located primarily in …

Agrobacterium Tumefaciens-Mediated Transformation Of Tobacco (Nicotiana Tabacum L.) Leaf Disks: Evaluation Of The Co-Cultivation Conditions To Increase Beta-Glucuronidase Gene Activity, Sunjung Park Jan 2006

Agrobacterium Tumefaciens-Mediated Transformation Of Tobacco (Nicotiana Tabacum L.) Leaf Disks: Evaluation Of The Co-Cultivation Conditions To Increase Beta-Glucuronidase Gene Activity, Sunjung Park

LSU Master's Theses

Agrobacterium tumefaciens-mediated transformation is generally used for genetic transformation of higher plants. Several experimental factors important for the increase of beta-glucuronidase (GUS) reporter gene activity were evaluated in this study using leaf disks of tobacco (Nicotiana tabacum L. cv. Xanthi). We found that co-cultivation temperature at 20C is the most critical factor to obtain the reproducible enhancement of GUS activity. pCAMBIA 1305.01 resulted in higher GUS activity than the other two pCAMBIA vectors 1301 and 1305.02. The highest GUS activity and transformation efficiency were achieved under the following experimental conditions: Agrobacterium tumefaciens strain LBA4404 containing pCAMBIA1305.01 was grown overnight at …

Anoxia Tolerance, Anaerobic Metabolism, And The Lack Of A Mitochondrial Permeability Transition In The Ghost Shrimp, Lepidophthalmus Louisianensis, Schmitt, 1935, Jeremy Dale Holman Jan 2006

Anoxia Tolerance, Anaerobic Metabolism, And The Lack Of A Mitochondrial Permeability Transition In The Ghost Shrimp, Lepidophthalmus Louisianensis, Schmitt, 1935, Jeremy Dale Holman

LSU Master's Theses

The ghost shrimp, Lepidophthalmus louisianensis, burrows up to meters deep in oxygen-limited marine sediments along the Gulf coast. During low tides these animals are subjected to extended periods of anoxia. The main objective of this study was to assess survival under anoxia and evaluate the physiological mechanisms that underlie the anoxia tolerance of this species. I observed large specimens of L. louisianensis (>2g) having an LT50 of 64 h under anoxia at 25º C. Smaller specimens (<1g) have a significantly higher LT50 of 113 h under identical conditions (P<0.0001). I measured whole body lactate levels in shrimp exposed to anoxia for up to 72 h, and recorded significant accumulation of this anaerobic end product (ANOVA, P<0.001). I also measured adenylates and arginine phosphate in shrimp exposed to anoxia for up to 48 h, and after a 24-h recovery period. Adenylates were not significantly altered during the anoxia regime, and reductions in arginine phosphate occurred after 12 and 24 h, but returned to normoxic values during recovery (ANOVA, P<0.001). While reserves of arginine phosphate are used to some extent to buffer losses in ATP, substantial contribution to the maintenance of energetic status comes from the high rate of anaerobic glycolysis. Energized mitochondria isolated from ghost shrimp hepatopancreas possess a pronounced ability to take up exogenous Ca2+ (compared to mitochondria-free controls) as measured by following the external free Ca …

Comparing Bermudagrass And Bahiagrass Cultivars At Different Stages Of Harvest For Dry Matter Yield And Nutrient Content, Ryan Thomas Dore'

LSU Master's Theses

Rapid growth of warm-season grasses such as bermudagrass (Cynodon dactylon) and bahiagrass (Paspalum notatum) is associated with a decline in their nutritional value. This study was initiated to provide production and composition data with different cultivars of bermudagrass (common, Russell, Jiggs) and bahiagrass (Tifton-9, Pensacola, Argentina). Dry matter (DM), ash, crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) composition and production were evaluated every two weeks for a ten-week period on six different cultivars. Also, Russell bermudagrass was evaluated in a second trial very similar to the first trial for composition and production but was started …
