Ectopic And Atretic Ostium Of Left Main Coronary Artery: From Interleaflet Triangle Between Left And Noncoronary Cusps, Ta-Chung Shen, Hsin-Hua Chou, Kuei-Ton Tsai Jan 2012

Ectopic And Atretic Ostium Of Left Main Coronary Artery: From Interleaflet Triangle Between Left And Noncoronary Cusps, Ta-Chung Shen, Hsin-Hua Chou, Kuei-Ton Tsai

The Texas Heart Institute Journal

Left main coronary artery atresia is an extremely rare coronary anomaly in which there is no left coronary ostium and the left main trunk ends blindly. Ectopic origin of the left coronary artery from the left ventricle is an even rarer condition. Herein, we describe the case of a 37-year-old woman whose left main coronary artery atresia was not corrected during previous surgical correction of patent ductus arteriosus and aortic insufficiency. Five years after that first operation, the patient developed severe angina and heart failure. She underwent coronary artery bypass grafting with greater saphenous vein directly to the left main …

Genetically Modified T-Cells Expressing Chimeric Antigen Receptors In The Treatment Of Cancer, Efrat Bruck Jan 2012

Genetically Modified T-Cells Expressing Chimeric Antigen Receptors In The Treatment Of Cancer, Efrat Bruck

The Science Journal of the Lander College of Arts and Sciences

Dr. Carl June and his colleagues at the University of Pennsylvania have succeeded in treating patients with Chronic Lymphocytic Leukemia using gene therapy. Two of the three patients treated sustained a complete remission and one a partial remission. The procedure involved transducing the patients’ T cells to express chimeric antigen receptors which target a particular protein found on both healthy and cancerous B cells. Following infusion of the newly transduced T cells, each patient developed clinical symptoms associated with an intense immune response. Shortly thereafter, tumors were completely eliminated in two of the patients and partially eliminated in the third. …

Modified-Release Drugs, Chedva Farkas

The Science Journal of the Lander College of Arts and Sciences

The following is an excerpt from the introduction to this article: Ever since the discovery of bacteria and their role in the disease process in the mid-1800s, scientists have been heavily involved in the discovery and development of drug therapies and their mechanism of action in the human body. Shortly after the initial discovery came the era of drug discovery of the late 1800s-early 1900s, also known as the “drug revolution” (Dash and Cudworth 1998). Although the drug revolution led to the rapid discovery of many new drugs, pharmacological factors such as dosage forms, drug delivery systems, plasma drug levels, …

Greenhouse Gas Fluxes In Southeastern U.S. Coastal Plain Wetlands Under Contrasting Land Uses, Jennifer L. Morse, Marcelo Ardón, Emily S. Bernhardt Jan 2012

Greenhouse Gas Fluxes In Southeastern U.S. Coastal Plain Wetlands Under Contrasting Land Uses, Jennifer L. Morse, Marcelo Ardón, Emily S. Bernhardt

Environmental Science and Management Faculty Publications and Presentations

Whether through sea level rise or wetland restoration, agricultural soils in coastal areas will be inundated at increasing rates, renewing connections to sensitive surface waters and raising critical questions about environmental trade-offs. Wetland restoration is often implemented in agricultural catchments to improve water quality through nutrient removal. Yet flooding of soils can also increase production of the greenhouse gases nitrous oxide and methane, representing a potential environmental trade-off. Our study aimed to quantify and compare greenhouse gas emissions from unmanaged and restored forested wetlands, as well as actively managed agricultural fields within the North Carolina coastal plain, USA. In sampling …

Patterns As Objects In Grace, Andrew P. Black, Michael Homer, James Noble, David J. Pearce, Kim B. Bruce Jan 2012

Patterns As Objects In Grace, Andrew P. Black, Michael Homer, James Noble, David J. Pearce, Kim B. Bruce

Computer Science Faculty Publications and Presentations

Object orientation and pattern matching are often seen as conflicting approaches to program design. Object oriented programs place type-dependent behaviour inside objects and invoke it via dynamic dispatch, while pattern matching programs place type-dependent behaviour outside data structures and invoke it via multiway conditionals (case statements). Grace is a new, dynamic, object-oriented language designed to support teaching: to this end, Grace needs to support both styles. In this paper we explain how this conflict can be resolved gracefully: by modelling patterns and cases as partial functions, reifying those functions as first-class objects, and then building up complex patterns from simpler …

Longitudinal Assessment Of Shifting Microbial Community Composition In Sandy Beaches Following The 2010 Deepwater Horizon Oil Spill And Remediation Efforts, Axita Ajaykumar Gupta

LSU Master's Theses

Sandy beaches are geological zones parallel to the shoreline where high energy, open ocean unconsolidated sediments are deposited and reworked. Sandy beaches represent critical ecosystems that support a wide variety of underappreciated biodiversity. Prior to the 2010 Deepwater Horizon oil spill in the Gulf of Mexico, the diversity and function of microbial communities in supratidal beach sediments along the Gulf of Mexico coastlines were not well understood. It was unclear if possible community compositional changes would occur during and following exposure to oil, or what impact the remediation efforts, such as sand washing, would have to the microbial communities and …

Reconfigurable Framework For High-Bandwidth Stream-Oriented Data Processing, Alexander Mykyta Jan 2012

Reconfigurable Framework For High-Bandwidth Stream-Oriented Data Processing, Alexander Mykyta

Theses

Designing a digital system that implements an assortment of specialized high performance algorithms can be costly. Considerable non-recurring engineering costs are required to develop an application specific integrated circuit (ASIC). Additionally, updating or adding features to a design requires the ASIC to be redesigned and refabricated. An alternative to using an ASIC is the field programmable gate array (FPGA). The modern FPGA's ability to be partially reconfigured at runtime allows for the device to have the flexibility normally associated with a processor, while also being able to implement digital logic like in an ASIC. This capability allows for multiple digital …

Convergence And Divergence In International Dispute Resolution Symposium, Peter Rutledge Jan 2012

Convergence And Divergence In International Dispute Resolution Symposium, Peter Rutledge

Journal of Dispute Resolution

This symposium submission draws heavily on law and economic literature to develop its thesis. Part I lays out the literature behind the parties' choice to opt for arbitration. It also builds upon that literature by attempting to sketch out some preliminary reasons why parties might opt for arbitration over another form of dispute resolution. Part II charts how, along various axes, arbitration has begun to converge with litigation - thereby depriving it of a comparative advantage that it once enjoyed - due to innovations in arbitration and innovations in the field of international civil litigation. In brief, the traditional advantages …

Autoregulation Of The Tfc6 Promoter And Effects Of Mis-Expression Of Tfc6 Protein Levels, Kimberly Le Blanc Jan 2012

Autoregulation Of The Tfc6 Promoter And Effects Of Mis-Expression Of Tfc6 Protein Levels, Kimberly Le Blanc

LSU Master's Theses

RNA Polymerase III (Pol III) is best characterized for its transcription of tRNA molecules. Interestingly, Pol III and its associated complexes have been found to be involved in the regulation of transcription of genes transcribed by RNA Polymerase II (Pol II) (Kleinschmidt, LeBlanc et al. 2011). Extra TFIIIC sites (ETC sites) are chromosomally located sites discovered in S. cerevisiae that bind the Pol III transcription factor TFIIIC only through B-box interactions. These chromosomal locations are not normally transcribed (Dieci and Sentenac 1996). One of the subunits of the TFIIIC complex, TFC6 has an ETC site (ETC6) in its promoter region …

Design Of Reverse Converters For The Multi-Moduli Residue Number Systems With Moduli Of Forms 2a, 2b - 1, 2c + 1, Naveen Kumar Samala

LSU Master's Theses

Residue number system (RNS) is a non-weighted integer number representation system that is capable of supporting parallel, carry-free and high speed arithmetic. This system is error-resilient and facilitates error detection, error correction and fault tolerance in digital systems. It finds applications in Digital Signal Processing (DSP) intensive computations like digital filtering, convolution, correlation, Discrete Fourier Transform, Fast Fourier Transform, etc. The basis for an RNS system is a moduli set consisting of relatively prime integers. Proper selection of this moduli set plays a significant role in RNS design because the speed of internal RNS arithmetic circuits as well as the …

The Effects Of Regulatory Uncertainty On The U.S. Acid Rain Program, Narendra Paramanand Jan 2012

The Effects Of Regulatory Uncertainty On The U.S. Acid Rain Program, Narendra Paramanand

LSU Master's Theses

Title IV of the Clean Air Act Amendments of 1990 (CAAA 1990) created the first large scale cap-and-trade program as a means to control acid rain in the United States. The program regulated the emission of sulfur dioxide (SO2) and nitrous oxide (NOx) in the atmosphere—the precursor to acid rain (formerly acid deposition). Economists have long argued for the use of market-based incentive approach as oppose to the traditional command-and-control methods for its ability to be efficient and cost-effective. Title IV went into full effect in 1995 and has been lauded among one of the most successful regulation as it …

Boron Composite Nanoparticles For Enhancement Of Bio-Fuel Combustion, Neng Wang Jan 2012

Boron Composite Nanoparticles For Enhancement Of Bio-Fuel Combustion, Neng Wang

LSU Master's Theses

Bio-fuels such as ethanol are good candidates to replace fossil fuels, which are being depleted, and whose combustion is associated with net production of greenhouse gases and other environmental issues. However, bio-fuels have low energy densities and can be subject to incomplete combustion. Boron is a promising additive for bio-fuels in combustion applications. It can increase their overall heat release and reduce ignition temperature, because boron itself is among the highest energy density materials. In this study, different B/rare earth oxide and B/Fe composite nanoparticles were produced by simple mechanical milling. Also, a new low temperature milling method was developed …

Phenotypic And Niche Evolution In The Antbirds (Aves: Thamnophilidae), Gustavo Adolfo Bravo Jan 2012

Phenotypic And Niche Evolution In The Antbirds (Aves: Thamnophilidae), Gustavo Adolfo Bravo

LSU Doctoral Dissertations

A pervasive goal in evolutionary biology has been to address why some clades are richer in species or phenotypic diversity than others. The Thamnophilidae is a large family of insectivorous passerine birds that provides great opportunities to study variation in species and phenotypic diversity. It comprises ca. 220 species that are mostly restricted to the lowlands and lower montane forests of the Neotropics. Its species are diverse in body size and shape, and the family exhibits high species richness, especially in Amazonian forests, where as many as 40 species may co-occur. Therefore, the fundamental research goal of my dissertation is …

What Does The ¹⁴C Method For Estimating Photosynthetic Rates In The Ocean Really Measure?, Shaofeng Pei Jan 2012

What Does The ¹⁴C Method For Estimating Photosynthetic Rates In The Ocean Really Measure?, Shaofeng Pei

LSU Doctoral Dissertations

The 14C method has been used extensively by both limnologists and oceanographers to measure photosynthetic rates in aquatic systems, and the large database of 14C measurements that now exists is the ground truth with which satellite algorithms for estimating marine photosynthetic rates on a basin and global scale have been calibrated. However, disconcerting uncertainties still remain with respect to whether and under what circumstances the 14C method provides an estimate of net or gross photosynthesis, or something in between. My study combined batch and continuous culture studies to clarify this ambiguous issue. The batch culture work with …

Communicating While Stimulated: The Effects Of Sensory-Processing Sensitivity On Behavior And Relationships, Christopher Charles Gearhart Jan 2012

Communicating While Stimulated: The Effects Of Sensory-Processing Sensitivity On Behavior And Relationships, Christopher Charles Gearhart

LSU Doctoral Dissertations

In light of claims made by Aron (1996, 2000; Aron & Aron, 1997), this dissertation tested the influence of sensory-processing sensitivity on communication via two sets of research questions. First, are highly sensitive persons more easily aroused by stimulation, and if so does this necessarily cause a decrease in affect recognition? Results of an experimental study (N = 342) indicate that highly sensitive persons (HSPs) were more distracted by audio stimulation, causing more errors in accuracy judgments on non-verbal decoding tests, most noticeably for facial expression detection. The implication is that, when aroused by stimulation in their environment, HSPs may …

Southern Bellas: The Construction Of Mestiza Identity In Southern Narratives, Wendy Aimee Braun Jan 2012

Southern Bellas: The Construction Of Mestiza Identity In Southern Narratives, Wendy Aimee Braun

LSU Doctoral Dissertations

This project analyzes representations and self-representations of Mestizas living in areas of the Deep South that lack a significant Latino presence. Incorporating a range of media, I take a comparative approach to Southern cultural narratives and propose a re-reading of these works through an examination of identity formation and cultural negotiation. By centering the Southern Mestiza, this dissertation advances concepts of intersectionality to address the role of region, as well as race and gender, in the representation and experiences of women often overlooked in Southern and U.S. Latino studies. The Introductory chapter summarizes the theoretical framework for the study, including …
