Regulation Of Intracellular Calcium Concentration By Nanosecond Pulsed Electric Fields, Shaka S. Scarlett, Jody A. White, Peter F. Blackmore, Karl H. Schoenbach, Juergen Kolb

Bioelectrics Publications

Changes in [Ca²⁺]_i response of individual Jurkat cells to nanosecond pulsed electric fields (nsPEFs) of 60 ns and field strengths of 25, 50, and 100 kV/cm were investigated. The magnitude of the nsPEF-induced rise in [Ca²⁺]_i was dependent on the electric field strength. With 25 and 50 kV/cm, the [Ca²⁺]_i response was due to the release of Ca²⁺ from intracellular stores and occurred in less than 18 ms. With 100 kV/cm, the increase in [Ca²⁺]_i was due to both internal release and to influx across the plasma …

Compulsive Hoarding In Children: Six Case Studies, Edward H. Plimpton, Randy O. Frost, Brianna C. Abbey, Whitney Dorer

Psychology: Faculty Publications

Semi-structured interviews were conducted with the parents of six children who showed signs of compulsive hoarding. The cases revealed a wide variety of hoarding behaviors. Hoarding manifested in difficulties in discarding and maintaining control over possessions. Few cases had problems with clutter or excessive acquisition. In three cases hoarding was episodic and stress-related. Most of the cases showed overlapping ADHD symptoms and a majority demonstrated problems with perfectionism. Only two had clear obsessive-compulsive disorder, although concerns about others touching or moving possessions, which was present in all of the cases, may represent a form of ordering and arranging compulsions. None …

Modeling And Experiments In Microchannels For The Separation And Detection Of Bacteria Using Antibody-Coated Filter And Quantum Dots, Narendra Sharma

Open Access Dissertations

Capture and detection of biomarkers for organisms is an important aspect in the design of a Lab-on-a-Chip (LOC). In this research, modeling and experiments were conducted to separate, capture and detect E. coli K12 bacteria from water samples using microchannels. Microchannels were fabricated using the soft lithography technique. The bacteria were separated from the sample and captured at a polyester filter whose surface was modified by attaching functional groups that had affinity for antibodies specific to E. coli K12. The bacteria bound to the functionalized filter were then tagged with quantum dots conjugated with E. coli K12-specific antibodies for detection …

Dna Methylation Analysis And Identification Of A Novel Antisense Transcript In The Peg3 Imprinted Domain, Jennifer Marian Huang

LSU Doctoral Dissertations

Genomic imprinting is a process that leads to the silencing of one allele of a gene in a parent of origin specific manner. Genes that are involved in this process are often regulated in clusters, one of which is the Peg3 (Paternally expressed gene 3) imprinted domain. We investigated this region for both CpG islands and long antisense transcripts, two common features of imprinted gene clusters. First, we performed a systematic survey of DNA methylation status of the CpG islands in this region of the mouse, cow, and human genomes. We identified two previously unreported differentially methylated regions (DMR): one …

Characterization Of Porcine Adipose Tissue-Derived Stem Cells, Kellie J. Williams

LSU Doctoral Dissertations

Nuclear transfer (NT) results in low success rates and research has reported problems with the welfare of cloned animals produced. Evidence suggests the use of a less differentiated donor cell, such as a stem cell, may lead to an increase in the efficiency of the NT procedure. Stem cell characteristics must be clearly defined in order to isolate, identify and optimally culture potential donor cells. Stem cell characteristics such as self-renewal and differentiation have not been identified in stem cells from porcine adipose tissue, an easily attainable tissue resource. The phenotypic profile of cell surface proteins and chromosomal stability of …

Particle-Chemical Interactions And Environmental Chemodynamics Of Fine And Ultrafine Particles In A Natural Disaster Scenario, Nicholas A. Ashley

LSU Doctoral Dissertations

The interactions of fine and ultrafine particles with chemicals play a dominant role in determining the mobility and availability of pollutants in the environment. Fine particles in sediments can sequester chemicals from the water column, and release volatile and semi-volatile organic compounds to the gas phase upon exposure to air. Ultrafine particles which are photoreactive can degrade these vapor-phase contaminants, and may transform the molecules into species which are more toxic or hazardous than the parent. As the widespread, commercial use of ultrafine particles becomes more common, understanding the chemodynamics of these particles and their interactions with chemicals in the …

Factors That Influence College Students Who Choose Engineering As Their Major To Presist In That Major To Their Fifth Semester, Kelli Elaine Wildman

LSU Doctoral Dissertations

Individuals, institutions, and society are affected by whether or not students persist in college; therefore, persistence and retention on college campuses is an important topic for higher education systems. However, little research has been done on program retention. Since engineering as a profession is expected to increase, it is imperative to have students persist in the major. The primary purpose of this study is to determine the influence of selected demographic and academic characteristics in the decision of first time in college (FTIC) traditional-age undergraduates who declare engineering as their major at admission to persist in the curriculum from second …

The Effects Of Being Placed In Special Education Classes Versus General Education Classes And Teacher Certification On Students' High-Stakes Testing Scores, Bethany Ann Porter

LSU Doctoral Dissertations

The introduction of new laws such as the amendments to the Individuals with Disabilities Education Act (IDEA, 1997) and the No Child Left Behind Act have changed education for special education students in the United States. Students with disabilities are now more frequently being held to the same standards as those students without disabilities. These federal laws are designed to help close the achievement gap among all students regardless of race, gender, poverty, or disability status. Special education students are now required to participate in statewide high-stakes testing programs alongside their nondisabled peers. Another movement involves including students with disabilities …

Collpas As Activity Hotspots For Frugivorous Bats (Stenodermatinae) In The Peruvian Amazon: Underlying Mechanisms And Conservation Implications, Adriana Bravo Ordonez

LSU Doctoral Dissertations

In western Amazonia, large numbers of frugivorous bats regularly visit natural forest clearings known locally as collpas (also called clay licks or mineral licks). Bats arrive at collpas to drink water that has accumulated in depressions created by larger mammals that consume soil. Although collpa visitation by bats appears relatively common in western Amazonia, little is known about its causes and its ecological implications. In this dissertation I describe general and seasonal patterns of collpa visitation by frugivorous bats in the Peruvian Amazon, and I investigate potential explanations for this unique behavior. Regardless of season, collpas seem to be activity …

Atom-Based Computer Simulation Studies Of Gas-To-Liquid Nucleation In Atmospherically Relevant Systems: Clarifying Discrepancies And Elucidating Mechanisms, Ricky Bendanillo Nellas

LSU Doctoral Dissertations

For over a century, nucleation for all systems was thought simplistically to be a process that advances through the formation of critical clusters with a well-defined composition. Our results show intriguing nucleation mechanisms that challenge the aforementioned notion. We employed the simple TraPPE-UA (transferable potential for phase equilibria – united atom) force field and the AVUS-HR approach (a combination of aggregation-volume-bias Monte Carlo, umbrella sampling, and histogram reweighting), to investigate the homogeneous vapor-to-liquid nucleation of various nucleating systems. We found out that these systems could nucleate through a variety of unique non-ideal mechanisms. Alongside existing experimental investigations, this dissertation presents …

A Simple Algorithm For Triconnectivity Of A Multigraph, Abusayeed Saifullah, Alper Ungor

All Computer Science and Engineering Research

Vertex-connectivity and edge-connectivity represent the extent to which a graph is connected. Study of these key properties of graphs plays an important role in varieties of computer science applications. Recent years have witnessed a number of linear time 3-edge-connectivity algorithms - with increasing simplicity. In contrast, the state-of-the-art algorithm for 3-vertex-connectivity due to Hopcroft and Tarjan lacks the simplicity in the sense of ease of implementation as well as the number of passes over the graph although its time and space complexity is theoretically linear. In this paper, we propose a linear time reduction from 3-vertex-connectivity to 3-edge- connectivity of …

Flap Endonuclease 1 Ensures Telomere Replication And Stability, Abhishek Saharia

All Theses and Dissertations (ETDs)

Telomeres, protein-DNA structures that distinguish the end of a chromosome from a bona fide DNA double strand break, are integral to genomic stability. High fidelity replication of telomeres is indispensable for their stability. Telomere replication is a challenging task that is completed through the coordinated actions of telomere binding proteins and DNA replication and repair proteins in ways that are not well understood. This work focuses on delineating the function of one DNA replication and repair protein, Flap Endonulcease 1: FEN1), in telomere replication and maintenance. I demonstrate that FEN1 is essential for the efficient replication of telomeres through its …

The Mechanisms And Roles Of Feedback Loops For Visual Processing, Jing Shao

All Theses and Dissertations (ETDs)

Signal flow in the brain is not unidirectional; feedback represents a key element in neural signal processing. To address the question on how do neural feedback loops work in terms of synapses, microcircuitry, and systems dynamics, we developed a chick midbrain slice preparation to study and characterize one important feedback loop within the avian visual system: isthmotectal feedbackloop. The isthmotectal feedback loop consists of the optic tectum: OT) and three nucleus isthmi: Imc, Ipc and SLu. The tectal layer 10 neurons project to ipsilateral Imc, Ipc and SLu in a topographic way. In turn Ipc and SLu send back topographical: …

Targeting The Dimerization Of Erbb Receptor Tyrosine Kinases, Rob Yang

All Theses and Dissertations (ETDs)

The epidermal growth factor receptor: EGFR) is a membrane receptor tyrosine kinase whose over-activation has been implicated to cause many human cancers. Novel strategies to inhibit the activation of EGF receptors other than the conventional antibody-based and tyrosine kinase inhibitors are virtually non-existent but could provide benefits both in the laboratory and clinical settings. In an effort to expand the current approaches, this thesis focused on targeting the homodimerization of the EGF receptors themselves and the heterodimerization of EGF receptors with the related ErbB2 receptor. Three sub-projects were completed in the process. The first project explored the feasibility of inhibiting …
