Determining Epigenetic Instability In Normal And Diseased Human Vulva, Kirk Hutchinson

LSU Master's Theses

Epigenetics is defined as the study of heritable changes of DNA. One such component of epigenetic regulation is DNA methylation in humans. In neoplastic cells epigenetic controls are often dysregulated, especially in the promoter region of CpG islands. Global hypomethylation along with region specific hypermethylation of CpG islands in the promoter region of tumor suppressor is often indicative of neoplastic cells. In cancer, CpG island cytosine hypermethylation has been observed in more than fifty genes, including known tumor suppressor and DNA repair genes. Squamous cell carcinoma (SCC), lichen sclerosis (LS), and adjacent normal tissues were obtained by radical vulvectomies of …

Physicochemical And Functional Properties Of Crawfish Chitosan As Affected By Different Processing Protocols, Sun-Ok Fernandez-Kim

LSU Master's Theses

Chitosan is made from chitin by a chemical process involving demineralization (DM), deproteinization (DP), decolorization (DC), and deacetylation (DA). Very little work has been done to demonstrate the effects of altering or excluding any of the processing steps on chitosan characteristics. The present study was undertaken to evaluate the effects of process modification during chitosan production on the physiochemical and functional properties of crawfish chitosans. Five experimental chitosan samples (DCMPA, DMCPA, DMPCA, DMPAC, DAMPC) prepared with modified processing protocols and the control (DPMCA - traditional chitosan production process) were evaluated and compared with the two commercial crab chitosans. All samples …

The objective of this study was to determine the fate of nitroglycerin in natural field soils. Nitroglycerin degradation was examined using a surface soil and an aquifer soil under aerobic and anaerobic conditions at three pH levels. Studies were also performed to determine the influence of a supplemental carbon source on degradation. Radiolabeled 14C-nitroglycerin was used to trace the partitioning between …

My Maiden Cowboy Names: Poems, Victoria Brockmeier

LSU Master's Theses

On the title: for a dichotomy of vulnerability and resistance; for self as plural and/or changeable; for acts of claiming. To hint at tone, setting, and content. On sound: to shape a poem's mood, and because these pieces should leave your mouth a little tired if you read them out loud. On lineation: to highlight the near-misses in language-ambiguities, double meanings, troublesome literalization-and to see these not as pitfalls but as opportunities. On stanza and strophe breaks: if a stanza is a room, the breaks between must be doorways, and who wants to sit down and rest in a doorway? …

A Performer's Guide To Virgil Thomson's Five Songs From William Blake, Andrew David Whitfield

LSU Doctoral Dissertations

Though perhaps his most well-known vocal works might be his operas, Four Saints in Three Acts and The Mother of Us All, American composer Virgil Thomson (1896-1989) did write nearly seventy songs for voice and piano, including several important song cycles. One of these cycles, the Five Songs from William Blake, represents an impressive composition for the baritone voice. Unfortunately, much of the previous scholarship about Thomson did not award these Blake songs adequate attention, nor was it able to draw upon many of the primary sources about Thomson’s life and work that are now available. The purpose of this …

Modulation Of Gabaergic Signaling In Retinal Amacrine Cells, Brian Kevin Hoffpauir

LSU Doctoral Dissertations

The intricate circuitry formed by amacrine cells in the inner plexiform layer (IPL) of the retina suggests that these interneurons play a major role in shaping the visual message. The majority of amacrine cells in the vertebrate retina are GABAergic. Thus, elucidating how GABAergic signaling is modulated in the IPL is critical in order to understand how the visual message is processed in the retina. The results presented here suggest that GABAergic signaling between amacrine cells can be modulated by the activation of metabotropic glutamate receptor 5 (mGluR5) or by the production of the second messenger, nitric oxide (NO). A …

Bakso (Traditional Indonesian Meatball) Properties With Postmortem Condition And Frozen Storage, Dino Rahardiyan

LSU Master's Theses

Bakso is a finely comminuted boiled Indonesian meat product that is traditionally made of starch, salt and emulsified prerigor or early postmortem meat and often sold from street vendors. Recently processors have begun to commercially manufacture bakso. This research was conducted to investigate the substitution of early postmortem meat with postrigor meat to allow more efficient manufacturing and raw material procurement. The first experiment was to determine the properties of bakso with three tapioca starch concentrations added to early or late postmortem beef. No differences (p<0.05) were observed in bakso properties of composition and texture, though bakso made of post-rigor meat had slightly less elasticity, strength and shear. These disadvantages were compensated by incorporating 15% starch concentration, indicating that the replacement of early postmortem meat with postrigor meat was applicable in industrial mass production of bakso. The second phase of experiments was to investigate the properties of bakso with different frozen storage times of raw postrigor meat and after different times of frozen storage for bakso made from postrigor and early postmortem meat. Postrigor meat substitution for early postmortem meat in bakso with 15% tapioca starch resulted in minimum composition and textural differences (p>0.05). Meat stored frozen for 2 and 4 months was still suitable as raw …

Arrive, Explore, Reflect: The Development And Evaluation Of A Web-Based Program To Introduce High School Students To Landscape Architecture, Courtney Bailey

LSU Master's Theses

The profession of landscape architecture has struggled with public perception since the mid-nineteenth century.

Assessing Landscape-Level Impacts Of Red Imported Fire Ants On Native Faunal Communities In Pine-Dominated Forests, Keri Elizabeth Landry

LSU Master's Theses

Since the accidental introduction of red imported fire ants (Solenopsis invicta Buren, RIFA) into Mobile, Alabama in the 1930’s, the invasion of this species into other areas across the southeast has increased drastically. RIFA have been implicated in the disruption of ecosystems and decreases in biodiversity. Most research on effects of RIFA on vertebrates and invertebrates have focused on small spatial scales and single species. I examined established populations of RIFA in relation to native ground-dwelling arthropods and small mammal communities in longleaf-pine and pine-hardwood forests. I evaluated the efficacy of using Amdro® to control RIFA and determined the effect …

Microsatellite Instability In Squamous Cell Carcinoma And Lichen Sclerosus Of The Vulva, Sidney Joseph Marlborough

LSU Master's Theses

The usefulness of detecting genomic instability in the form of microsatellite instability (MSI) has been examined in a number of cancers. Squamous cell carcinoma (SCC) and adjacent normal and lichen sclerosis (LS) samples were taken from patients with radical vulvectomies. Vulvar SCC samples were compared with adjacent normal samples using four oligonucleotide markers (BAT-25, BAT-26, D10S208 and D10S587) found to be informative with other carcinomas. Using polymerase chain reaction techniques, 30 vulvar SCC DNA samples were examined for MSI. BAT-26 displayed the highest level of MSI and was considered to be the most sensitive marker in studying vulvar SCC. There …

Solving A Locational Distribution Problem Of Non-Toxic Solid Waste On The Island Of Puerto Rico, Sandra A. Soto

LSU Master's Theses

The island of Puerto Rico is confronting a crisis in waste management due to inadequate management from the local government, the decreasing number of landfills available, high population density, and paucity of places for waste disposal. This research develops a least-cost model for the disposal and transportation of non-hazardous solid waste. Location-allocation (LA) and Geographic Information Systems (GIS) software are used to analyze the efficiency of the present pattern of waste allocation and to identify a near-to-optimal assignment of waste for the landfills in operation today and the landfills that will be open by 2008. The “near-to-optimal” models obtained from …

Minimum Dogma And Religious Toleration, Clinton Bryan Barron

LSU Master's Theses

This thesis examines issues that emerge from the investigation of the relationship between John Locke's arguments for religious toleration as found in his Letter Concerning Toleration and his construction of a minimum dogma for Christianity in his The Reasonableness of Christianity. The first chapter follows the development of minimum dogma from its origin in the experience Eric Voegelin terms the leap in being, through Xenophanes' concept of "seemliness," to the minimum dogmas of Plato. The second chapter examines the use of minimum dogma in theories of religious toleration by More and Spinoza. The final chapter examines the work of John …

The Figuration Of Caliban In The Constellation Of Postcolonial Theory, Paulus Sarwoto

LSU Master's Theses

The surrogation of Caliban from Shakespeare’s The Tempest to Césaire’s A Tempest has always been related to colonialism. In Shakespeare’s time, Caliban, depicted as half animal, served to represent the Other in an emerging colonial discourse. As opposed to Shakespeare’s character, Césaire’s Caliban is blatantly black and racially oppressed. Césaire indicates that A Tempest is an adaptation of Shakespeare’s The Tempest for black theater. As an adaptation, the play reinterprets the figure of Caliban to express postcolonial attitudes of the time. This thesis addresses the questions of how the figure of Caliban in Shakespeare’s play fits into the discourse of …

Genetics And Functions Of Herpes Simplex Virus Type 1 Membrane Proteins In Virus-Induced Cell Fusion, Virion Morphogenesis And Egress, Jeffrey Michael Melancon

LSU Doctoral Dissertations

The Herpes Simplex Virus life cycle contains a number of membrane fusion events that must function properly to ensure a productive infection, including: virus attachment and entry into susceptible cells, de-envelopment at the outer nuclear lamellae, and virus-induced cell-to-cell fusion. A virus-free cell fusion assay was recently developed in order to attempt to understand the underlying mechanisms that are responsible for viral fusion events and was utilized in order to investigate the effect of mutations targeted to the carboxyl terminus of gB. We showed that the predicted alpha helical domain H17b within the carboxyl-terminus of gB is involved in both …

Development Of Outdoor Educational Landscapes In Forested Wetlands Of Louisiana's Atchafalaya Basin, Margaret Ann Mcclain

LSU Master's Theses

Natural landscapes, formed by eons of plant succession, are changing or disappearing as a result of rapid urban development and industrial growth. In addition, the human population explosion pressures are being applied to alter the urban/wildland interface in the United States and throughout the world. Many of Louisiana wetlands are subjected to these pressures and have caused change and loss in forested wetland areas. Most of the Mississippi River Delta consists of wetlands in a state of transition to either open water or degraded hardwood forest due to the effects of several key factors. Being a native of south Louisiana, …

Mineral Utilization In Poultry As Affected By Virginiamycin Or Mineral Source, Tanika Ivel O'Connor-Dennie

LSU Master's Theses

Four experiments were conducted to evaluate the effects of diets with reduced Ca or nonphytate P (nPP) levels with supplemental virginiamycin (Vm) on growth performance and bone response variables in chicks. All diets were corn-soybean meal based and all treatments were replicated six or eight times with five or six chicks each. Reducing dietary nPP from 0.45 to 0.15, 0.25, or 0.35% decreased most growth and bone response variables. The addition of Vm to diets containing 0.35% nPP and above increased both growth and bone response variables. The addition of Vm to diets containing 0.25% nPP and below had no …

Online Heat Transfer Measurement And Analysis For Sugar Mill Evaporators, David Timothy Solberg

LSU Master's Theses

Fouling and scaling in evaporators has been an area of great interest to raw sugar mills for a number of years and many of the mechanisms causing the scale and the rates of scaling are unknown. In an attempt to quantify the scaling rates and measure the scaling, an online model has been developed to model a system of evaporators. Monitoring the heat transfer coefficient as a function of time enabled measurement of the scaling rate by monitoring the heat transfer coefficient as it decreased with time. It is assumed that the scaling on the juice side of the evaporators …
