New Synthetic Methodologies For The Construction And Optimization Of Natural Products, Amir E. Wahba Jan 2011

New Synthetic Methodologies For The Construction And Optimization Of Natural Products, Amir E. Wahba

Electronic Theses and Dissertations

Toxicity associated with bioactive natural products is considered as a major obstacle in the process of drug discovery. Manzamine A (MA) is one such candidate that requires optimization to overcome the toxicity problem. The manzamine alkaloids represents a unique class of natural products that have shown a diverse range of bioactivities including antimicrobial, antiparasitic, cytotoxicity, anti-inflammatory, pesticidial, and was shown to possess activity against HIV-1 and AIDS opportunistic infections. The greatest potential for the manzamine alkaloids appears to be against malaria and neuroinflammation. Experimental and modeling studies suggested that the planer ?-carboline moiety can act as DNA intercalator and hence …

Chorister Formation Preferences In A Women's Choir, Janna Montgomery Jan 2011

Chorister Formation Preferences In A Women's Choir, Janna Montgomery

Electronic Theses and Dissertations

While conductors and audience members are not committed to a single formation, choristers have a clear preference: sectional or mixed. Why is this? Participants in this study included forty-six members of an auditioned women's choir from a large southern university who completed a survey after singing in sectional and mixed formation. These SSAA results maintain previous research findings by James Daugherty, Debra Atkinson, and Christopher Aspaas, et al. from female choristers in SATB settings: most women prefer mixed formation. All 46 of the participants (100%) perceived that formation generally affects the choral sound, so they think formation is important. Women's …

The Effects Of Chronic Prophylactic Naproxen Sodium On Skeletal Muscle Adaptation To Resistance Exercise In Recreationally-Trained College-Aged Males, Christi Brewer Jan 2011

The Effects Of Chronic Prophylactic Naproxen Sodium On Skeletal Muscle Adaptation To Resistance Exercise In Recreationally-Trained College-Aged Males, Christi Brewer

Electronic Theses and Dissertations

Resistance exercise causes exercise-induced muscle injury (EIMI), triggering an acute local inflammatory response associated with delayed-onset muscle soreness (DOMS). DOMS is characterized by a predictable discomfort and decreased level of muscle performance and is believed to be the product of both mechanical and inflammatory processes. From the latter perspective, non-steroidal anti-inflammatory drugs (NSAIDs) have been investigated for their potential to alleviate DOMS-associated symptoms. Such analgesics exert their effects by blocking the formation of prostaglandins; however, prostaglandins, specifically prostaglandin F 2?, also play an important role in skeletal muscle regeneration. While some have advocated the use of NSAIDs for the relief …

Effect Of Uv-A Irradiance On Lipid Accumulation In Nannochloropsis Oculata, Rathy Srinivas

Electronic Theses and Dissertations

The marine microalgae Nannochloropsis spp. are of both ecological and economic importance as they contribute to the base of the food chain of marine systems, and can accumulate a considerable amount of lipids. Their lipids can be grouped into two categories, storage lipids, which are mainly triglycerides (TGs), and structural lipids, which are composed of polyunsaturated fatty acids (PUFAs). PUFAs are essential nutrients for both aquatic animals and humans, while TGs can be transesterified to produce biodiesel. Lipid formation in microalgae depends on several environmental factors and Nannochloropsis spp. have been shown to accumulate excess storage lipids under stressful conditions. …

Characterization Of Intermolecular Pi-Type Interactions Using Sophisticated Quantum Mechanical, Electronic Structure Computations, Emily Joy Carrell Jan 2011

Characterization Of Intermolecular Pi-Type Interactions Using Sophisticated Quantum Mechanical, Electronic Structure Computations, Emily Joy Carrell

Electronic Theses and Dissertations

Much like the instrumentation in an experimental lab, computational chemists use computers to solve the mathematical equations that describe the physics of electrons to understand the chemistry involved. The combination of the two main components of computational chemistry, the basis set and method, determines the ``cost'' (disk, memory, and CPU time) of a computation. A variety of basis sets and methods have been developed in the past century. The focus of this report is to accurately describe non-covalent interactions with the use of various quantum computational techniques. In Chapter 1 a brief discussion on the theory behind computational chemistry is …

With Malice Towards None: Six Stories And A Novella, Burke Nixon Jan 2011

With Malice Towards None: Six Stories And A Novella, Burke Nixon

Electronic Theses and Dissertations

A fiction collection consisting of six short stories folloby a novella. The pieces attempt to be comic, but also--with debatable success--to be more than just comic. As the title suggests, one of the collection's thematic concerns is mercy and its absence. Most of the pieces are set in Texas; characters in the collection include a female student in an absurdly incompetent public high school, a parking cop, the best friend of a stand-up comedian, an Abilene man whose life goal is to be struck by lightning, and an unselfconscious grandfather character, who bookends the beginning and end of the collection. …

Epigenetic Effects Of Benzo(A)Pyrene In Fundulus Heteroclitus And Danio Rerio, Xiefan Fang Jan 2011

Epigenetic Effects Of Benzo(A)Pyrene In Fundulus Heteroclitus And Danio Rerio, Xiefan Fang

Electronic Theses and Dissertations

DNA methylation is one of the epigenetic mechanisms that controls gene expression and is vulnerable to early life environmental toxicant exposures. Our goal was to use two fish models, Fundulus heteroclitus and Danio rerio (zebrafish), to study the benzo(a)pyrene (BaP) effects on DNA methylation status and whether the alterations could contribute to BaP-mediated reproductive and developmental toxicities. Initially, we used Fundulus to study BaP effects on glycine N-methyltransferase (GNMT) expression throughout development. Fundulus embryos were exposed to waterborne BaP at nominally 10 or 100 μg/L and both GNMT mRNA expression and enzyme activity were measured. Quantitative PCR and whole mount …

The Seaside Resort Towns Of Cape May And Atlantic City, New Jersey Development, Class Consciousness, And The Culture Of Leisure In The Mid To Late Victorian Era, Tatyana Ressetar Jan 2011

The Seaside Resort Towns Of Cape May And Atlantic City, New Jersey Development, Class Consciousness, And The Culture Of Leisure In The Mid To Late Victorian Era, Tatyana Ressetar

Electronic Theses and Dissertations

"Victorianism" is a highly controversial, sometimes ironic, term penned by historians throughout various works that has come to hold dramatic weight in both its meaning and its influence. Though the term is usually most closely associated with nineteenth century England, Victorianism was a highly influential movement in American culture simultaneously as well, specifically in the spheres of home, work, and play. Of those, "play," or leisure, is undoubtedly the least explored, especially before the latter decades of the twentieth century. Prior to this period, most literature about the Victorians, with the exception of a few works, only dealt with masculinity, …

A Laudable Ambition Fired Her Soul Conduct Fiction Helps Define Republican Womanhood, Female Communities, And Women's Education In The Works Of Judith Sargent Murray, Hannah Webster Foster, And Susanna Haswell Rowson, Jessica Crystal Workman

Electronic Theses and Dissertations

This study examines the major works of Judith Sargent Murray, Hannah Webster Foster, and Susanna Haswell Rowson, three major writers of the 1790s whose writing responds to the ideologies of the early American Republic. I suggest that Murray, Foster, and Rowson write conduct fiction which responds to the changing attitudes toward women and education after the American Revolution. Using fiction, these authors comment on the republican woman, the need for women’s education, and the necessity for women to gather in communities for support. Despite the prevailing notion that reading too many novels would corrupt young women, Judith Sargent Murray’s novella, …

Evolutionary Relationships Among Staphylococci And The Prevention Of Staphylococcus Aureus Nasal Colonization, Ryan Paul Lamers Jan 2011

Evolutionary Relationships Among Staphylococci And The Prevention Of Staphylococcus Aureus Nasal Colonization, Ryan Paul Lamers

Electronic Theses and Dissertations

Staphylococcus is a significant cause of human infection and mortality, worldwide. Currently, there are greater than 60 taxa within Staphylococcus, and nearly all are pathogenic. The collective potential for virulence among species of Staphylococcus heightens the overall clinical significance of this genus and argues for a thorough understanding of the evolutionary relationships among species. Within Staphylococcus, aureus is the most common cause of human infection, where nasal carriage of this bacterium is a known risk factor for autoinfection. The predisposition to infection by nasal carriers of S. aureus, and the ease with which strains are transferred between individuals, suggests that …

Prediction Of Survival Of Early Stages Lung Cancer Patients Based On Er Beta Cellular Expressions And Epidemiological Data, Evgeny Martinenko Jan 2011

Prediction Of Survival Of Early Stages Lung Cancer Patients Based On Er Beta Cellular Expressions And Epidemiological Data, Evgeny Martinenko

Electronic Theses and Dissertations

We attempted a mathematical model for expected prognosis of lung cancer patients based on a multivariate analysis of the values of ER-interacting proteins (ERbeta) and a membrane bound, glycosylated phosphoprotein MUC1), and patients clinical data recorded at the time of initial surgery. We demonstrate that, even with the limited sample size available to use, combination of clinical and biochemical data (in particular, associated with ERbeta and MUC1) allows to predict survival of lung cancer patients with about 80% accuracy while prediction on the basis of clinical data only gives about 70% accuracy. The present work can be viewed as a …

Indirect Estimates Of Gene Flow And Its Conservation Implications In The Striped Newt (Notophthalmus Perstriatus), Sarah Elizabeth May Jan 2011

Indirect Estimates Of Gene Flow And Its Conservation Implications In The Striped Newt (Notophthalmus Perstriatus), Sarah Elizabeth May

Electronic Theses and Dissertations

This study used indirect methods to estimate patterns of gene flow in a rare salamander species, the striped newt (Notophthalmus perstriatus). First, we used combined genetic and ecological methods to determine whether populations that appear to exist in two regions separated by 125 km, exhibited genetic and ecological distinctness such that the regions demarcate separate conservation units. Using mtDNA (cyt-b), we found that haplotypes were shared between localities within each region but none were shared between regions. Niche-based distribution modeling revealed significant differences in the ecological setting between the two regions. In combination, the absence of evidence for recent genetic …

The Effects Of Urbanization On Cypress (Taxodium Distichum) In Central Florida, Lisa A. Mccauley

Electronic Theses and Dissertations

Urbanization is accelerating in the United States and is contributing to fragmentation of natural habitats, causing changes in species composition and declines in native species. Human population growth in Orlando is typical of growth in the southeastern United States and throughout the range of cypress (Taxodium distichum). Orlando has numerous isolated cypress wetlands, called cypress domes, and many remain among the current urbanized area. This makes Orlando ideal to study the effects of urbanization on cypress domes. Specifically, I tested how urbanization and its effects on fragmentation, hydrology, and fire regime) affected (a) the numbers and spatial pattern of cypress …

Synthesis, Characterization And Antibacterial Activity Of Silver Embedded Silica Nanoparticle/Nanogel Formulation, Roseline Menezes Jan 2011

Synthesis, Characterization And Antibacterial Activity Of Silver Embedded Silica Nanoparticle/Nanogel Formulation, Roseline Menezes

Electronic Theses and Dissertations

The antibacterial property of silver (Ag) has been known since ancient time. It is reported in the literature that silver nanoparticles (AgNPs) exhibit improved antibacterial properties in comparison to silver ions of equivalent metallic Ag concentration. Such improvement in antibacterial activities is due to the high surface area to volume ratio of AgNPs (which facilitates interaction with the bacterial cells), increased release of silver ions and direct intra-cellular uptake of AgNPs leading to localized release of Ag ions. To date, over 300 consumer products containing AgNPs are available in the market and the inventory is rapidly expanding. The antibacterial efficacy …

Expression Of Trichoderma Reesei Beta]-Mannanase In Tobacco Chloroplasts And Its Utilization In Lignocellulosic Woody Biomass Hydrolysis, Pankaj M. Agrawal

Electronic Theses and Dissertations

Lignocellulosic ethanol offers a promising alternative to conventional fossil fuels. One among the major limitations in the lignocellulosic biomass hydrolysis is unavailability of efficient and environmentally biomass degrading technologies. Plantbased production of these enzymes on large scale offers a cost effective solution. Cellulases, hemicellulases including mannanases and other accessory enzymes are required for conversion of lignocellulosic biomass into fermentable sugars. β- mannanase catalyzes endo-hydrolysis of the mannan backbone, a major constituent of woody biomass. In this study, man1 gene encoding β-mannanase was isolated from Trichoderma reesei and expressed via the chloroplast genome. PCR and Southern hybridization analysis confirmed the site-specific …

Modeling Transport And Protein Adsorption In Microfluidic Systems, Craig Finch Jan 2011

Modeling Transport And Protein Adsorption In Microfluidic Systems, Craig Finch

Electronic Theses and Dissertations

Mass transport limitations and surface interactions are important phenomena in microfluidic devices. The flow of water is laminar at small scales and the absence of turbulent mixing can lead to transport limitations, especially for reactions that take place at surfaces. Microscale devices have a high ratio of surface area to volume, and proteins are known to adsorb preferentially at interfaces. Protein adsorption plays a significant role in biology by mediating critical processes such as the attachment of cells to surfaces, the immune response and the coagulation of blood. Simulation tools that can quantitatively predict transport and protein adsorption will enable …

The American School Discipline Debate And The Persistence Of Corporal Punishment In Southern Public Schools, David M. Hargrove Jan 2011

The American School Discipline Debate And The Persistence Of Corporal Punishment In Southern Public Schools, David M. Hargrove

Electronic Theses and Dissertations

The dissertation examines the history of American school discipline and corporal punishment in southern public schools. Pedagogical literature, court reports, and popular fiction show that school discipline was a controversial topic throughout American history. The conflict over corporal punishment in schools led to a 1976 Supreme Court decision, Ingraham v. Wright, affirming the power of educators to use corporal punishment. When the school discipline debate peaked late in the twentieth century, most American schools no longer used corporal punishment but southern educators continued to paddle students, especially African American school children. By the twenty-first century, southern city schools adopted non-violent …

The Role Of Mental Health Professionals In Cases Of Child Sexual Abuse As Seen Through The Eyes Of Judges, S. Lynn Etheridge Jan 2011

The Role Of Mental Health Professionals In Cases Of Child Sexual Abuse As Seen Through The Eyes Of Judges, S. Lynn Etheridge

Electronic Theses and Dissertations

The involvement of Mental Health Professionals (MHPs) in cases of child sexual abuse (CSA) is complex and intimidating. There are legal rules and academic suggestions to guide the MHP in this endeavor, but in experience, these rules and suggestions are lacking. Current literature and research indicates that there is little if any direct knowledge on how judges perceive MHPs who testify before them in court. A qualitative phenomenological inquiry that directly interviefive judges about their perceptions of MHPs in cases of CSA was undertaken. The results indicate that MHPs should be more intentional about their choices regarding involvement in court, …

The Effects Of Seasonal Changes And Turbidity On Swimming Performance In White Crappie Pomoxis Annularis And Black Crappie Pomoxis Nigromaculatus., Caleb Joseph Gaston

Electronic Theses and Dissertations

Factors that affect swimming performance in fish can also affect fitness. I tested the effects of time of day, season and turbidity on swimming performance in black crappie Pomoxis nigromaculatus and white crappie Pomoxis annularis. These closely related fish co-occur and their relative abundance is thought to be governed by the levels of turbidity in the form of suspended sediments. Black crappie predominate in clear bodies of water and exhibited significantly greater critical swimming speeds in clear water than did white crappie during spring days and winter nights. A significant reduction in critical swimming speed was observed in black crappie …
