Neither Natchez Nor Tara: An Environmental Historial Geography Of The Upper Pearl River Basin Of Mississippi, Protohistoric Period To 1940., Frederick William Sunderman Jan 2001

Neither Natchez Nor Tara: An Environmental Historial Geography Of The Upper Pearl River Basin Of Mississippi, Protohistoric Period To 1940., Frederick William Sunderman

LSU Historical Dissertations and Theses

This study examines the contrasting themes of land degradation and environmental stewardship of farming enterprises in the regional context of the Upper Pearl River Basin of Mississippi. Both the previous imagery and analysis of Southern Cotton Belt agriculture emphasize the profligate nature of farming practices. The contribution this study makes is to amend both the stock images and macro-analyses of Southern cotton culture. Analysis at the sub-regional level demonstrates that many farmers actually practiced sound land management techniques. Reconstructing the experiences of farmers in the Upper Pearl River Basin provides examples of ways in which regional distinctions amend widely conceived …

Some Technical Vocabulary Of Rhetorical Invention In The Treatise Of Anonymous Seguerianus, Hermogenes' "On Statis", And Book Three Of The [Pseudo-]Hermogenic Work "On Invention", Mark Allen Williams

LSU Historical Dissertations and Theses

From the debates of the Christian councils to the homilies of the local priests, from the opaque scripting of the Byzantine epistle to the clarities of stasis theory, from the entertaining fictions of declamation to the promulgation of Byzantine cannon law, the citizens of Byzantium were never far from the rhetorical, and they themselves knew it. But the development of rhetorical theory in the Greek West has gained little attention, and what has been given to it has generally concentrated on questions of style. This dissertation examines some of the most basic qualities of that theory of rhetorical invention which …

T -Cell Cytokines And Equine Nematode Infections., Jenifer Dee Edmonds Jan 2001

T -Cell Cytokines And Equine Nematode Infections., Jenifer Dee Edmonds

LSU Historical Dissertations and Theses

To address the role of parasites on subsequent antigenic challenge, humoral, lymphoproliferative and cytokine responses to a single intramuscular injection of keyhole limpet haemocyanin (KLH) were compared between groups of ponies with high, medium or low gastrointestinal parasite burdens. Heavy and moderately parasitised animals showed a trend towards reduced KLH-specific lymphoproliferation and reduced antigen specific total immunoglobulin, IgG(T) and IgA compared to lightly parasitised ponies. The peripheral blood mononuclear cells (PBMC) from medium and heavily parasitised ponies also had significantly lower levels of IL-4. These data indicate that heavily parasitised animals have uniformly decreased cellular and humoral immune responses to …

An Economic Analysis Of The Allocation Of Research Funding At The National Institutes Of Health., Janet B. Daniel Jan 2001

An Economic Analysis Of The Allocation Of Research Funding At The National Institutes Of Health., Janet B. Daniel

LSU Historical Dissertations and Theses

Our model examines the allocation of medical research funds at the National Institutes of Health using public interest theory, incremental budgeting theory, and special interest group theory. We use the allocation of research funds among various diseases and measures of the burden of disease on the population to test the hypothesis that the N.I.H. is allocating funds on a pure public interest basis, to test for incremental budgeting effects, and to test for the influence of lobbying and other political variables representing special interest groups. We use pooled cross-sectional, time-series data in a one-way fixed effects model, and also use …

Body Condition, Leptin, And Reproductive Characteristics In Horses., Laura Roland Gentry Jan 2001

Body Condition, Leptin, And Reproductive Characteristics In Horses., Laura Roland Gentry

LSU Historical Dissertations and Theses

A series of experiments was conducted to gain a better understanding of the effects of nutrition and hormonal manipulation on the reproductive processes of the horse. In Experiment 1, body condition score (BCS) and ultrasonic backfat measurements were highly correlated in mares, especially over the tailhead area. In Experiment 2, high BCS (HBCS) mares continued to ovulate during the winter anestrous period, whereas low BCS (LBCS) mares went deeply anestrous. Daily hormone concentrations were not affected by BCS, however, responses to hormonal challenges indicated cyclicity in HBCS mares and reproductive quiescence in LBCS mares. In Experiment 3, treatment of average …

Evaluating The Taxonomic Status Of The Great White Heron (Ardea Herodias Occidentalis) Using Morphological, Behavioral And Genetic Evidence., Heather Louise Mcguire Jan 2001

Evaluating The Taxonomic Status Of The Great White Heron (Ardea Herodias Occidentalis) Using Morphological, Behavioral And Genetic Evidence., Heather Louise Mcguire

LSU Historical Dissertations and Theses

The Great White Heron was originally described as a distinct species (Ardea occidentalis), but is currently considered to be the white morph of a polymorphic Great Blue Heron subspecies (A. herodias occidentalis). Great White and Great Blue heron breeding ranges overlap in the Florida Keys (USA), providing an opportunity to evaluate the degree to which these two taxa are reproductively isolated. The current classification leads to predictions of no significant size difference (H01), random mate choice (H02), and no genetic divergence (H03) between sympatric white and blue herons. Sympatric Great White and Great Blue herons did not differ significantly in …

Effects Of Nitric Oxide Synthase Inhibitors On Equine And Bovine Follicular Dynamics And Steroidogenesis., Carlos Roberto Fontes Pinto Jan 2001

Effects Of Nitric Oxide Synthase Inhibitors On Equine And Bovine Follicular Dynamics And Steroidogenesis., Carlos Roberto Fontes Pinto

LSU Historical Dissertations and Theses

Current scientific literature has shown that: (1) NO is a pro-ovulatory agent and inhibition of its production inhibits ovulation, and (2) NO has strong antisteroidogenic activity, especially on estradiol (E2) production by granulosa cells. The experiments described in this dissertation were designed to answer the following questions involving effects of NO on ovarian physiology: (1) is the inhibitory effect of nitric oxide synthase (NOS) inhibitors on ovulation irreversible (follicular atresia) or temporary (delayed ovulation)? and (2) what is the relationship between NO and hCG-induced preovulatory luteinization? Accordingly, cycling mares were subjected to treatment with NOS inhibitors (L-NAME or aminoguanidine) during …

Production, Process Design And Quality Characterization Of Catfish Visceral Oil., Subramaniam Sathivel

LSU Historical Dissertations and Theses

Between 45--55% of viscera, head, skin, intestine and slurries are generally generated as byproducts or waste from catfish filleting process. Our preliminary study showed that the crude fat content of the whole catfish viscera was 30--35% (wet basis) and the total o-3 fatty acids of oils recovered from the whole and/or portioned viscera ranged from 4.3--20.9 mg/g (dry basis). Catfish viscera may serve as an excellent source of health-promoting oil. Yield of purified (deodorized) catfish visceral oil was 65.7% and contained considerable amounts of DHA (1.21 mg/g of oil) and omega-3 fatty acid (4.6 mg/g of oil). A rapid microwave-assisted …

An Improved In Vitro Model For The Study Of Mycobacterium Leprae/Schwann Cell Interactions, Deanna Alisa Hagge Jan 2001

An Improved In Vitro Model For The Study Of Mycobacterium Leprae/Schwann Cell Interactions, Deanna Alisa Hagge

LSU Doctoral Dissertations

Globally, millions of leprosy patients suffer irreversible peripheral nerve damage resulting in blindness or other disabilities as a consequence of Mycobacterium leprae infection. Schwann cells, the neural target of M. leprae, have a central role in leprosy histopathology including axonotrophy, altered myelin architecture and demyelination. The mechanisms of nerve damage have not been fully elucidated but appear to be the direct result of M. leprae within Schwann cells or a combined effect with an aggressive immune response to M. leprae within the nerves. There is no standardized in vitro model for the study of M. leprae interactions with the Schwann …

The Synthesis Of Deuterated Arylamine Dna Adducts For Use In The Development Of An Isotope Dilution Lc/Ms/Ms Method, Philip Dmitri Olsen Jan 2001

The Synthesis Of Deuterated Arylamine Dna Adducts For Use In The Development Of An Isotope Dilution Lc/Ms/Ms Method, Philip Dmitri Olsen

LSU Doctoral Dissertations

Polycyclic aromatic amines (arylamines) are a class of chemical carcinogens that are prevalent in environmental and industrial settings. In order to study the mechanism of their toxicity a quantitative and qualitative detection method was developed to measure the C8-adenine adducts of benzidine and 2-aminofluorene in DNA samples. To do this a novel synthetic method using a palladium catalyst was developed to prepare authentic and deuterated arylamine adducts to serve as standards. These standards were then used to develop a high performance liquid chromatography, electrospray, tandem mass spectrometry, isotope dilution, detection method. To demonstrate the validity of this method two spike …

Palm Community Development And Influence On Seedling Establishment In A Tropical Moist Forest, Panama, Krista Lynn Farris Lopez Jan 2001

Palm Community Development And Influence On Seedling Establishment In A Tropical Moist Forest, Panama, Krista Lynn Farris Lopez

LSU Master's Theses

Plants often modify microsite conditions important for seedling establishment. Palms may reduce light levels and produce deep leaf litter; both may suppress seedlings, affecting the local abundance, distribution, and species composition of tree seedlings. The abundance and composition of palms were examined along a tropical forest chronosequence at the Barro Colorado Nature Monument, Panama. Palms were sampled along transects in secondary (20, 40, 70, and 100 y in fallow) and old-growth forests. Palm abundance and basal area significantly increased with forest age. Palm distribution was driven by the most abundant palm, Oenocarpus mapora, which accounted for 60% of the total …

The Evaluation Of Pcr-Based Techniques For The Detection Of Fecal Indicator Organisms In Environmental Samples, Quinesha Laticia Perry Jan 2001

The Evaluation Of Pcr-Based Techniques For The Detection Of Fecal Indicator Organisms In Environmental Samples, Quinesha Laticia Perry

LSU Master's Theses

Escherichia coli is the indicator organism of choice for the detection of fecal contamination. Standard methods for detecting fecal contamination often rely on detecting fecal coliforms. While this practice if highly efficient in most applications, when used with the sediment-laden waters of Louisiana, free-living soil bacteria, such as Klebsiella pneumoniae were shown to inflate the fecal coliform counts. An accurate assessment of the contamination problem requires methods that detect E. coli. To detect E. coli, several of species-specific genes were tested before the gadAB genes were selected. The polymerase chain reaction (PCR) was chosen to detect these genes using a …

"Of One Kind Or Another": Rape In The Fiction Of Eudora Welty, Nicole M. Donald Jan 2001

"Of One Kind Or Another": Rape In The Fiction Of Eudora Welty, Nicole M. Donald

LSU Master's Theses

"Of One Kind or Another:" Rape in the Fiction of Eudora Welty explores the ways in which Eudora Welty's repeated inclusion of rape in her fiction reveals and questions southern society and women's roles in it. Despite the vague, even confusing language with which she describes the incidents of rape. Welty offers a rich, forceful commentary upon the culture and women's roles in it. The ambiguity with which she describes rape reveals ambivalence toward the society that Welty may be said at once to protect and to expose. An examination of Welty's use of rape in her fiction reveals a …

Eosinophil Major Basic Protein-1 Does Not Contribute To Allergen-Induced Airway Pathologies In Mouse Models Of Asthma, K. L. Denzler, S. C. Farmer, J. R. Crosby, M. Borchers, G. Cieslewicz, K. A. Larson, S. Cormier-Regard, N. A. Lee, J. J. Lee Nov 2000

Eosinophil Major Basic Protein-1 Does Not Contribute To Allergen-Induced Airway Pathologies In Mouse Models Of Asthma, K. L. Denzler, S. C. Farmer, J. R. Crosby, M. Borchers, G. Cieslewicz, K. A. Larson, S. Cormier-Regard, N. A. Lee, J. J. Lee

Faculty Publications

The relationship between eosinophils and the development of Ag-induced pulmonary pathologies, including airway hyper-responsiveness, was investigated using mice deficient for the secondary granule component, major basic protein-1 (mMBP-1). The loss of mMBP-1 had no effect on OVA-induced airway histopathologies or inflammatory cell recruitment. Lung function measurements of knockout mice demonstrated a generalized hyporeactivity to methacholine-induced airflow changes (relative to wild type); however, this baseline phenotype was observable only with methacholine; no relative airflow changes were observed in response to another nonspecific stimulus (serotonin). Moreover, OVA sensitization/aerosol challenge of wild-type and mMBP-1(-/-) mice resulted in identical dose-response changes to either methacholine …

Potential Gene Conversion And Source Genes For Recently Integrated Alu Elements, Astrid M. Roy, Marion L. Carroll, Son V. Nguyen, Abdel Halim Salem, Michael Oldridge, Andrew O.M. Wilkie, Mark A. Batzer, Prescott L. Deininger

Faculty Publications

Alu elements comprise >10% of the human genome. We have used a computational biology approach to analyze the human genomic DNA sequence databases to determine the impact of gene conversion on the sequence diversity of recently integrated Alu elements and to identify Alu elements that were potentially retroposition competent. We analyzed 269 Alu Ya5 elements and identified 23 members of a new Alu subfamily termed Ya5a2 with an estimated copy number of 35 members, including the de novo Alu insertion in the NFI gene. Our analysis of Alu elements containing one to four (Ya1-Ya4) of the Ya5 subfamily-specific mutations suggests …

The Breeding Ecology Of White-Faced Ibis In The Lower Carson River Basin, Nevada, Eric Patrick Kelchlin Oct 2000

The Breeding Ecology Of White-Faced Ibis In The Lower Carson River Basin, Nevada, Eric Patrick Kelchlin

LSU Historical Dissertations and Theses

The Great Basin White-faced Ibis (Plegadis chihi) population is recognized as a Species of Management because of its small population size, limited number of traditional breeding sites, and vulnerability to habitat loss. The ability to predict future population trends and develop wetland management strategies is limited because many aspects of their breeding ecology and population dynamics are unknown. 1 examined White-faced Ibis nesting ecology and breeding habitat selection at the Lower Carson River Basin, Nevada, from 1995-1997, and the relationship between the local surface water conditions and trends in the number of breeding pairs from 1970-1997 on a local and …

Discovery Of A Novel, Paternally Expressed Ubiquitin-Specific Processing Protease Gene Through Comparative Analysis Of An Imprinted Region Of Mouse Chromosome 7 And Human Chromosome 19q13.4, Joomyeong Kim, Vladimir N. Noskov, Xiaochen Lu, Anne Bergmann, Xiaojia Ren, Tiffany Warth, Paul Richardson, Natalya Kouprina, Lisa Stubbs

Faculty Publications

Using mouse BAC clones spanning an imprinted interval of proximal mouse chromosome 7 and the genomic sequence of the related interval of human chromosome 19q13.4, we have identified a novel mouse gene, Usp29 (ubiquitin-specific processing protease 29), near two known imprinted genes, Peg3 and Zim1. Gene Usp29 is located directly adjacent to Peg3 in a ″head-to-head″ orientation, and comprises exons distributed over a genomic distance of at least 400 kb. A similar human gene is also found in the homologous location in human chromosome 19q13.4. The mouse Usp29 gene is also imprinted and is transcribed mainly from the paternal allele …

High Phosphorylation Efficiency And Depression Of Uncoupled Respiration In Mitochondria Under Hypoxia, Erich Gnaiger, Gabriela Méndez, Steven C. Hand Sep 2000

High Phosphorylation Efficiency And Depression Of Uncoupled Respiration In Mitochondria Under Hypoxia, Erich Gnaiger, Gabriela Méndez, Steven C. Hand

Faculty Publications

Mitochondria are confronted with low oxygen levels in the microenvironment within tissues; yet, isolated mitochondria are routinely studied under air-saturated conditions that are effectively hyperoxic, increase oxidative stress, and may impair mitochondrial function. Under hypoxia, on the other hand, respiration and ATP supply are restricted. Under these conditions of oxygen limitation, any compromise in the coupling of oxidative phosphorylation to oxygen consumption could accentuate ATP depletion, leading to metabolic failure. To address this issue, we have developed the approach of oxygen-injection microcalorimetry and ADP-injection respirometry for evaluating mitochondrial function at limiting oxygen supply. Whereas phosphorylation efficiency drops during ADP limitation …

Response Of Atmospheric Methane Consumption By Maine Forest Soils To Exogenous Aluminum Salts, K. Nanba, G. M. King Sep 2000

Response Of Atmospheric Methane Consumption By Maine Forest Soils To Exogenous Aluminum Salts, K. Nanba, G. M. King

Faculty Publications

Atmospheric methane consumption by Maine forest soils was inhibited by additions of environmentally relevant levels of aluminum. Aluminum chloride was more inhibitory than nitrate or sulfate salts, but its effect was comparable to that of a chelated form of aluminum. Inhibition could be explained in part by the lower soil pH values which resulted from aluminum addition. However, significantly greater inhibition by aluminum than by mineral acids at equivalent soil pH values indicated that inhibition also resulted from direct effects of aluminum per se. The extent of inhibition by exogenous aluminum increased with increasing methane concentration for soils incubated in …
