Evaluating Remote Setting Techniques For Oyster (Crassostrea Virginica) Seed Production In Louisiana, Victoria D. Ippolito Jan 2010

Evaluating Remote Setting Techniques For Oyster (Crassostrea Virginica) Seed Production In Louisiana, Victoria D. Ippolito

LSU Master's Theses

Research was conducted to implement remote setting technology for the commercial- scale production of oysters on alternative cultch material in Louisiana. Genetic research has created an enhanced oyster stock for commercial cultivation. Since the Louisiana oyster industry relies on natural seed production for product, they are unable to utilize these new advances and are never guaranteed a reliable source of oyster seed. Remote setting is one way of producing a consistent supply of genetically improved oysters. Cultch material for oyster settlement is a limiting resource. Several alternatives to clamshell have been explored. The objectives of this study are: (1) test …

Investigating The Use Of Bioengineered Oyster Reefs As A Method Of Shoreline Protection And Carbon Storage, Daniel D. Dehon Jan 2010

Investigating The Use Of Bioengineered Oyster Reefs As A Method Of Shoreline Protection And Carbon Storage, Daniel D. Dehon

LSU Master's Theses

The Louisiana Gulf Coast is losing land at an alarming rate for a combination of reasons. At the same time carbon dioxide is accumulating in the atmosphere and the oceans by the increased burning of fossil fuels. Therefore, bioengineered oyster dominated artificial reefs have been developed in an effort to mitigate erosion while storing carbon in the oyster shells. These reefs support the growth of a native oyster species, Crassostrea virginica, which are considered ecological engineers and serve to improve water quality, protect coastal wetlands, capture and store carbon, and enhance the economy. Evaluation of test pieces showed the addition …

Hepatotoxic Cyanobacterial Blooms In Louisiana's Estuaries: Analysis Of Risk To Blue Crab (Callinectes Sapidus) Following Exposure To Microcystins, Ana Cristina Garcia Jan 2010

Hepatotoxic Cyanobacterial Blooms In Louisiana's Estuaries: Analysis Of Risk To Blue Crab (Callinectes Sapidus) Following Exposure To Microcystins, Ana Cristina Garcia

LSU Master's Theses

The most common toxins detected following freshwater harmful algal blooms are microcystins, a group of hepatotoxins produced by cyanobacteria (e.g., Microcystis and Anabaena spp.). Preference for filter-feeding prey, including bivalves, makes the blue crab, Callinectes sapidus, vulnerable to microcystin contamination and makes the commercially important crab a potential vector of microcystins. I used a combination of field and laboratory studies to determine blue crab vulnerability to microcystin contamination and consequent impacts on crab physiology. Samples collected from a hyper-eutrophic freshwater lake, Lac des Allemands, Louisiana, were analyzed for cyanobacterial abundances and microcystins in surface water and blue crabs using light-microscopy …

Evolutionarily Conserved Cis-Acting Elements Regulate Lineage-Specific Expression Of Ifng, Anand Balasubramani Jan 2010

Evolutionarily Conserved Cis-Acting Elements Regulate Lineage-Specific Expression Of Ifng, Anand Balasubramani

All ETDs from UAB

The ability to differentially manipulate available genetic information in order to generate diverse cellular identities represents an innovation of complex multicellular eukaryotic organisms. Cis-acting modules that regulate transcription play extremely important roles in ensuring lineage-specific expression of genes that define cellular identities. In our studies, using Interferon-gamma (IFN-gamma, a cytokine encoded by the gene Ifng), a cytokine encoded by T, NK and NKT cells as a model, we have identified and characterized the roles of key cis regulatory elements that facilitate T lineage specific induction as well as repression of Ifng transcription. In particular, our studies have highlighted the role …

Molecular Mechanisms Of Breast Cancer Metastasis: Gap Junction Intercellular Communication And The Bone Microenvironment, Thomas Morgan Bodenstine Jan 2010

Molecular Mechanisms Of Breast Cancer Metastasis: Gap Junction Intercellular Communication And The Bone Microenvironment, Thomas Morgan Bodenstine

All ETDs from UAB

Metastatic disease accounts for the overwhelming majority of cancer related deaths. More specifically, breast cancer remains one of the leading causes of death in women and breast cancer cells metastasize to bone more than any other secondary site. Upon arriving within the bone microenvironment, breast cancer cells interact with bone marrow cells, leading to changes in bone biology that favor growth of the cancer cells. Additionally, some cancer cells are capable of direct cellular communication with cells at metastatic sites via dysregulation of a family of proteins known as connexins. This direct, physical communication is known as gap junctional intercellular …

Preclinical Pharmacology Of Novel Synthetic Iminoquinones As Anticancer Agents, Scharri Ezell Jan 2010

Preclinical Pharmacology Of Novel Synthetic Iminoquinones As Anticancer Agents, Scharri Ezell

All ETDs from UAB

Prostate cancer is the most common male malignancy and the second leading cause of cancer related death in the United States. Despite recent advances in the detection, diagnosis, and treatment of prostate cancer, there is a need for more effective therapies. Unfortunately, most conventional therapeutic modalities, such as androgen ablation therapy, frequently result in androgen-independent cancers. These cancers are typically more aggressive, metastatic, and resistant to chemotherapeutic agents than androgen-dependent prostate cancer. Therefore, agents that are effective against both androgen-sensitive and androgen-independent, as well as genetically diverse cancers are critically needed. The objective of the dissertation research was to address …

Identification And Validation Of Biodosimetry Markers In Multiple Models Of Radiation Exposure, Ashley Nicole Filiano Jan 2010

Identification And Validation Of Biodosimetry Markers In Multiple Models Of Radiation Exposure, Ashley Nicole Filiano

All ETDs from UAB

Following a radiological or nuclear disaster, radiation dose assessment is imperative to minimize morbidity and mortality through rationally directed medical intervention. Current methods of retrospective dosimetry are not amenable to mass exposure scenarios and remain limited to monitoring of clinical symptoms (nausea/vomiting and lymphocyte depletion) and cytogenetic analysis. The goal of this study was to identify radiation biomarkers capable of qualitative (non-irradiated/irradiated) and quantitative (dose) assessment of radiation exposure. Initial analyses revealed 17 radiation-responsive cytokine/chemokine genes in blood samples from 6 pediatric cancer patients undergoing fractionated total body irradiation (TBI). These 17 genes were combined with 29 additional IR-inducible genes …

The Effects Of Environmental Ozone Exposure On Vascular Function, Oxidative Stress, And Atherosclerosis, Gin Chuang Jan 2010

The Effects Of Environmental Ozone Exposure On Vascular Function, Oxidative Stress, And Atherosclerosis, Gin Chuang

All ETDs from UAB

Exposure to air pollutants are known to induce airway inflammation, decrease lung function, and worsen existing pulmonary conditions such as asthma. Additionally, air pollutant exposure has also been shown to impact cardiovascular health. Although these pollutant-induced cardiovascular effects were considered to be mediated by the direct action of pollutants upon the cardiovascular tissue and/or the indirect release of pro-inflammatory factors into the circulation, the relative contribution of the two pathways remained equivocal. Recently, several epidemiology studies associated ozone exposure with cardiovascular mortalities. However, relatively few studies to date have examined ozone in this context. In order to address our hypothesis …

Impacts Of Marsh Loss And Fragmentation On Microhabitat Use By Estuarine Nekton In Southwest Louisiana, John Alexander Gordon Jan 2010

Impacts Of Marsh Loss And Fragmentation On Microhabitat Use By Estuarine Nekton In Southwest Louisiana, John Alexander Gordon

LSU Master's Theses

In Louisiana, the extensive loss and fragmentation of coastal marshes has prompted inquires into the impacts these processes may have on estuarine-dependant nekton. To date, research on nekton response to marsh loss and fragmentation has been limited to landscape-level studies which focus on the relationship between nekton productivity and the availability of marsh edge. These studies have relied on the assumption that marsh edges provide the same level of support to nekton regardless of the degree of surrounding marsh loss or fragmentation. This study tested this assumption by investigating the impacts of marsh loss and fragmentation on marsh-edge characteristics and …

The Relationship Among Self-Efficacy, Negative Self-Statements, And Social Anxiety In Children: A Mediation, Brittany Nicole Moree Jan 2010

The Relationship Among Self-Efficacy, Negative Self-Statements, And Social Anxiety In Children: A Mediation, Brittany Nicole Moree

LSU Master's Theses

Evidence suggests that general self-efficacy, one’s beliefs about his or her global abilities, and social self-efficacy, one’s beliefs in his or her ability to navigate social situations, are strongly connected to levels of social anxiety. Negative self-statements, also known as negative self-referent cognitions, have also been linked with levels of social anxiety. Although self-efficacy and negative self-statements have been shown to be important variables in the phenomenology and maintenance of social anxiety in children, they have yet to be examined in conjunction with one another. The purpose of this study was to examine the relationship between negative self-statements and selfefficacy …

"To Liberate Communication": The Realist And Paul Krassner's 1960s, Terry Joel Wagner Jan 2010

"To Liberate Communication": The Realist And Paul Krassner's 1960s, Terry Joel Wagner

LSU Master's Theses

Paul Krassner began publishing a small-circulation magazine called The Realist in New York City in 1958 because he believed there existed excessive restraints on speech in American culture. The publication began with a combination of earnest critiques and good-humored satires on such topics as organized religion, sexual mores, Cold War paranoia, and civil rights. By the mid-sixties, the magazine was enlarging the space not just for what opinions could be expressed but also for the way those opinions were expressed and, in the process, testing the boundaries of obscenity. As Krassner became a bitter opponent of the Vietnam War and …

The Influence Of Two Estrogens On The Sex And Ovarian Development Of Eastern Oysters (Crassostrea Virginica) Maintained In A Closed Recirculating System, Wesley Michael Burnside Jan 2010

The Influence Of Two Estrogens On The Sex And Ovarian Development Of Eastern Oysters (Crassostrea Virginica) Maintained In A Closed Recirculating System, Wesley Michael Burnside

LSU Master's Theses

As a multi-million dollar industry, production of the eastern oyster Crassostrea virginica is significant to the economy of the nation’s coastal regions. The cost of commercial oyster aquaculture has higher inputs than the oyster fishery, but larger, better quality oysters can be produced for culture by the stable availability of triploid individuals.

The goal of this project was to determine if the use of an estrogen, estradiol-17β or estradiol-3-benzoate, at a consistent environmental temperature would increase the percentage of females in a population, as well as ovarian development of eastern oysters. Ultimately, this could be applied to triploids to increase …
