Optimizing Computer-Aided Colonic Polyp Detection For Ct Colonography By Evolving The Pareto Front, Jiang Li, Adam Huang, Jack Tao, Jiamin Liu, Robert L. Van Uitert, Nicholas Petrick, Ronald Summers

Electrical & Computer Engineering Faculty Publications

A multiobjective genetic algorithm is designed to optimize a computer-aided detection (CAD) system for identifying colonic polyps. Colonic polyps appear as elliptical protrusions on the inner surface of the colon. Curvature-based features for colonic polyp detection have proved to be successful in several CT colonography (CTC) CAD systems. Our CTC CAD program uses a sequential classifier to form initial polyp detections on the colon surface. The classifier utilizes a set of thresholds on curvature-based features to cluster suspicious colon surface regions into polyp candidates. The thresholds were previously chosen experimentally by using feature histograms. The chosen thresholds were effective for …

Parameter Optimization For Image Denoising Based On Block Matching And 3d Collaborative Filtering, Ramu Pedada, Emin Kugu, Jiang Li, Zhanfeng Yue, Yuzhong Shen, Josien P.W. Pluim (Ed.), Benoit M. Dawant (Ed.)

Electrical & Computer Engineering Faculty Publications

Clinical MRI images are generally corrupted by random noise during acquisition with blurred subtle structure features. Many denoising methods have been proposed to remove noise from corrupted images at the expense of distorted structure features. Therefore, there is always compromise between removing noise and preserving structure information for denoising methods. For a specific denoising method, it is crucial to tune it so that the best tradeoff can be obtained. In this paper, we define several cost functions to assess the quality of noise removal and that of structure information preserved in the denoised image. Strength Pareto Evolutionary Algorithm 2 (SPEA2) …

Automatic Diagnosis For Prostate Cancer Using Run-Length Matrix Method, Xiaoyan Sun, Shao-Hui Chuang, Jiang Li, Frederic Mckenzie, Nico Karssemeijer (Ed.), Maryellen L. Giger (Ed.)

Electrical & Computer Engineering Faculty Publications

Prostate cancer is the most common type of cancer and the second leading cause of cancer death among men in US¹. Quantitative assessment of prostate histology provides potential automatic classification of prostate lesions and prediction of response to therapy. Traditionally, prostate cancer diagnosis is made by the analysis of prostate-specific antigen (PSA) levels and histopathological images of biopsy samples under microscopes. In this application, we utilize a texture analysis method based on the run-length matrix for identifying tissue abnormalities in prostate histology. A tissue sample was collected from a radical prostatectomy, H&E fixed, and assessed by a pathologist …

A Divided-Attention Timed Stepping Accuracy Task As A Procedural Learning Intervention Improves Balance And Functional Performance In Healthy Older Adults, Susan Joy Leach

LSU Doctoral Dissertations

For both healthy individuals and individuals at high risk of falling, certain environments, such as a dual-task situation, require more resources than others to prevent a loss of balance. Stepping assessment tasks can be used to predict falls, and it has been suggested that impaired voluntary stepping may be a contributing factor to falls (Lord & Fitzpatrick, 2001). In this research, a stepping task was used not as an assessment, but as a therapeutic intervention. The purpose of this research was to determine how training with a task that provides a procedural learning environment can affect balance and functional outcomes. …

Tumor Necrosis Factor Induced Oxidative Stress In The Central Nervous System Contributes To Sympathoexcitation In Heart Failure, Anuradha Guggilam

LSU Doctoral Dissertations

Despite advanced therapeutic strategies for post-myocardial infarction (MI) patients, many ultimately develop congestive heart failure (CHF), rendering the disease a major cause of death in the United States. MI is associated with an acute increase in sympathetic nervous system activity, becoming persistent in CHF patients. Increased pro-inflammatory cytokines (PICs) following MI are implicated in the pathogenesis of CHF. The increase in tumor necrosis factor (TNF), a primary PIC, correlates closely with heart disease severity. Moreover, central PIC production increases post-MI, and can affect the brain’s cardiovascular regulatory regions that control sympathoexcitation. Therefore, understanding how PICs modulate sympathoexcitation is important for …

The Anatomy Of Anatomia: Dissection And The Organization Of Knowledge In British Literature, 1500-1800, Matthew Scott Landers

LSU Doctoral Dissertations

This dissertation develops a conceptual history of human anatomy, both as a discipline and as an epistemological model. Building on recent scholarship in the history of science, I argue that the basic organization of anatomical inquiry inspired a number of literary productions during the seventeenth and eighteenth centuries. This project counters important critical trends of the last five decades, which have focused on the ambiguous characterization of an anatomical genre without providing sufficient medical context. I argue that intellectual history reveals a persistent epistemological analogy between the body and textual arrangements of human knowledge. By examining this analogical structure, it …

Characterizing The Epidemiology Of Isospora Amphiboluri In Captive Bearded Dragons (Pogona Vitticeps), Michael Robison Walden

LSU Doctoral Dissertations

First described in 1967, Isospora amphiboluri has become recognized as an important pathogen of bearded dragons. To date, no cross-sectional, pathogenesis, or treatment study has been performed to shed light on the epidemiology or treatment of I.amphiboluri. Two large breeding populations of bearded dragons were examined for the presence of I. amphiboluri oocysts using sucrose flotation and fecal direct saline smears. Parasites were more likely to be identified on fecal flotation (p= 0.03). A previously unidentified Eimeria species was examined and described as a new species for which we suggest the name Eimeria pogonae. To develop an understanding of the …

Inuit Qaujimajatuqangit And Adaptive Co-Management: A Case Study Of Narwhal Co-Management In Arctic Bay, Nunavut, Aaron T. Dale

Theses and Dissertations (Comprehensive)

Since 2001 the community of Arctic Bay, located on north-western Baffin Island, in Nunavut, Canada, has been experimenting with a new approach to narwhal management—‘community-based’ narwhal managemet. The new management system has developed some decision-making powers to the local Hunters’ and Trappers’ Organization, who are empowered/required to draft by-laws to govern the hunt. Community-based narwhal management links local, regional, territorial, and national actors and agencies in a co-management arrangement that draws its powers from, and is steered by, the Nunavut Final Agreement (1993), the comprehensive land claims agreement between the Inuit of Nunavut and Her Majesty the Queen in Right …

Lesbian, Gay, And Bisexual Supervisees’ Experiences Of Lgb-Affirmative And Nonaffirmative Supervision, Alan W. Burkard, Sarah Knox, Shirley A. Hess, Jill Schultz

College of Education Faculty Research and Publications

Lesbian, gay, and bisexual (LGB) supervisees were interviewed regarding their experiences of LGB affirmative and nonaffirmative supervision. Supervisees were asked to describe one of each type of event (i.e., affirmative, nonaffirmative) from their past supervision. In LGB-affirmative supervision, all supervisees felt supported in their LGB-affirmative work with clients. Supervisees perceived that the affirming events also positively affected the supervision relationship, client outcomes, and themselves as supervisees. In LGB nonaffirming supervision, supervisees perceived supervisors to be biased or oppressive toward supervisees’ clients or themselves on the basis of LGB concerns or identity. From supervisees’ perspectives, the nonaffirming events negatively affected the …

Thoracoscopic Decortication Vs Tube Thoracostomy With Fibrinolysis For Empyema In Children: A Prospective, Randomized Trial., Shawn D. St Peter, Kuojen Tsao, Troy L. Spilde, Scott J. Keckler, Christopher J. Harrison, Mary Anne Jackson, Susan W. Sharp, Walter S. Andrews, Douglas C. Rivard, Frank P. Morello, G W. Holcomb Iii, Daniel J. Ostlie

Manuscripts, Articles, Book Chapters and Other Papers

PURPOSE: Management of empyema has been debated in the literature for decades. Although both primary video-assisted thoracoscopic surgery (VATS) and tube thoracostomy with pleural instillation of fibrinolytics have been shown to result in early resolution when compared to tube thoracostomy alone, there is a lack of comparative data between these modes of management. Therefore, we conducted a prospective, randomized trial comparing VATS to fibrinolytic therapy in children with empyema.

METHODS: After Institutional Review Board approval, children defined as having empyema by either loculation on imaging or more than 10,000 white blood cells/microL were treated with VATS or fibrinolysis. Based on …

Toddlers With Developmental Delays And Challenging Behaviors, Kathryn M. Keller, Robert A. Fox

College of Education Faculty Research and Publications

Behavior problems and parental expectations and practices were studied in a sample of 58 toddlers with developmental disabilities who were consecutively referred to a mental health clinic. The majority of children (70.7%) exceeded the clinical cut-off score for significant behavior problems including tantrums, aggression, defiance, and hyperactivity, and 77.6% met the DSM-IV criteria for a psychiatric diagnosis with oppositional defiant disorder being the most common. Consistent with previous research, child behavior problems were related to parental use of verbal and corporal punishment and were detrimental to the quality of the parent-child relationship. A new finding was that parental expectations also …

Rex1p Deficiency Leads To Accumulation Of Precursor Initiator TrnaMet And Polyadenylation Of Substrate Rnas In Saccharomyces Cerevisiae, Sarah G. Ozanick, Xuying Wang, Michael Costanzo, Renee L. Brost, Charles Boone, James T. Anderson

Biological Sciences Faculty Research and Publications

A synthetic genetic array was used to identify lethal and slow-growth phenotypes produced when a mutation in TRM6, which encodes a tRNA modification enzyme subunit, was combined with the deletion of any non-essential gene in Saccharomyces cerevisiae. We found that deletion of the REX1 gene resulted in a slow-growth phenotype in the trm6-504 strain. Previously, REX1 was shown to be involved in processing the 3′ ends of 5S rRNA and the dimeric tRNA^Arg-tRNA^Asp. In this study, we have discovered a requirement for Rex1p in processing the 3′ end of tRNA_i^Met precursors and …

Li, Lynn A. Sleeper, Richard V. Williams, Jami C. Levine, Brian W. Mccrindle, Andrew M. Atz, Darlene Servedio, Lynn Mahony, Pediatric Heart Network Investigators, Girish S. Shirali

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Angiotensin converting enzyme (ACE) inhibitors are known to improve clinical outcome and ventricular function in adults with heart failure. Infants with single-ventricle physiology show abnormalities in ventricular function as well as poor growth. The ability of an ACE inhibitor to preserve ventricular function and improve growth in these infants is unknown.

METHODS: The Pediatric Heart Network designed a randomized, double-blind trial to compare outcomes in infants with single-ventricle physiology receiving enalapril or placebo. Neonates < or =45 days old were eligible. The primary outcome is weight-for-age Z-score at 14 months of age. Secondary outcomes include other measures of somatic growth, laboratory and functional measures of heart failure, developmental indices, measures of ventricular size and function, and the relationship of the renin-angiotensin-aldosterone system genotype to the response to enalapril. The incidence and spectrum of adverse events will also be compared between treatment groups.

RESULTS: A total of 1,245 neonates were screened and 533 (43%) were eligible. The consent rate was 43%; 230 subjects were enrolled. Parental reluctance to …

Single-Molecule Detection Of Unique Genome Signatures: Applications In Molecular Diagnostics And Homeland Security, Jason M. Emory

LSU Doctoral Dissertations

Single-molecule detection (SMD) offers an attractive approach for identifying the presence of certain markers that can be used for in vitro molecular diagnostics in a near real-time format. The ability to eliminate sample processing steps afforded by the ultra-high sensitivity associated with SMD yields an increased sampling pipeline. When SMD and microfluidics are used in conjunction with nucleic acid-based assays such as the ligase detection reaction coupled with single-pair fluorescent resonance energy transfer (LDR-spFRET), complete molecular profiling and screening of certain cancers, pathogenic bacteria, and other biomarkers becomes possible at remarkable speeds and sensitivities with high specificity. The merging of …
