Polyamines As Olfactory Stimuli In Goldfish, Shane Howell Rolen Jan 2002

Polyamines As Olfactory Stimuli In Goldfish, Shane Howell Rolen

LSU Master's Theses

The effects of polyamines as odorants to goldfish olfactory receptors were investigated by in vivo electrophysiological recordings. Electro-olfactogram (EOG) recordings indicated that polyamines (putrescine, cadaverine and spermine) are potent olfactory stimuli for goldfish with estimated electrophysiological thresholds of 10-100nM, similar to that for L-arginine, the most stimulatory amino acid. Although thresholds were similar, the magnitude of the EOG responses to intermediate and high concentrations of polyamines dwarfed those to amino acids and single amine containing compounds (amylamine and butylamine). The EOG responses to 0.1mM putrescine, cadaverine and spermine were, respectively, 4.2x, 4.3x and 10.3x that of the standard, 0.1mM L-arginine. …

Open Space For The Public: An Evaluation Of Designed Open Spaces On Urban University Campuses, Elizabeth Errett Neil

LSU Master's Theses

A public university that is perceived as being physically open and accessible to the general public can help promote a better relationship between the city and the university. Public urban universities have a responsibility to provide usable, accessible open space for the public. Universities and designers recognize the importance of integrating their campus into the community and creating spaces for students that allow for outdoor and social activities. However, little attention has been given to the need to provide spaces that allow for outdoor and social activities for the public. The public urban university was used as a model because …

The Matson And Mayville (M&M) Seizure Scale: An Assessment Of Psychological And Environmental Variables Contributing To Seizure Activity In Persons With Mental Retardation, Erik Andrew Mayville

LSU Doctoral Dissertations

Seizure activity can be debilitating across a number of physical, social, occupational, and personal domains. Given the deficits in all of these areas frequently present in persons with mental retardation, the control and elimination of seizures is a primary goal for individuals with both mental retardation and epilepsy. Antiepileptic medication can reduce seizure activity. However, this intervention often carries with it a range of untoward side effects that may adversely affect clients over what is typically a long-term treatment regimen. Over the last 20 years, literature has emerged emphasizing the importance of environmental variables in the initiation and maintenance of …

The Role Of Cysteine 230 And Lysine 238 Of Biotin Carboxylase In The Deprotonation Of Biotin And Synthesis Of Bisubstrate Analogy Inhibitor Of Carboxyltransferase, Keith Logan Levert Jan 2002

The Role Of Cysteine 230 And Lysine 238 Of Biotin Carboxylase In The Deprotonation Of Biotin And Synthesis Of Bisubstrate Analogy Inhibitor Of Carboxyltransferase, Keith Logan Levert

LSU Doctoral Dissertations

Acetyl-CoA carboxylase catalyzes the first step in the synthesis of fatty acids. The Escherichia coli form of the enzyme consists of a biotin carboxylase protein, a biotin carboxyl carrier protein, and a carboxyltransferase protein. This enzyme uses the cofactor biotin as a carboxyl carrier. In order for the carboxylation of biotin to occur, biotin must be deprotonated at its N-1 position. It has been proposed that the active site residues cysteine 230 and lysine 238 act as an acid-base pair to deprotonate biotin. To test this hypothesis, site-directed mutagenesis was used to mutate cysteine 230 to alanine (C230A) and lysine …

Technical Feasibility Of Flakeboard Production From Recycled Cca-Treated Wood, Wei Li Jan 2002

Technical Feasibility Of Flakeboard Production From Recycled Cca-Treated Wood, Wei Li

LSU Master's Theses

Chromated copper arsenate (CCA) treated wood is an economical, durable and aesthetically pleasing residential material used for many exterior application such as decks, fences, playground equipment, utility poles, and others. It has been most widely used in North America since the 1970’s. A large volume of CCA-treated wood is currently coming out of service. Traditional landfilling or incineration is environmentally unacceptable. Recycling CCA-treated wood into composite products is one alternative to ease the disposal problem. It also has the potential to relieve harvesting pressure from the nation's forestlands. After recycling, the remaining CCA content in the wood can still have …

Thermal Rheological Analysis Of Cure Process Of Epoxy Prepreg, Liangfeng Sun Jan 2002

Thermal Rheological Analysis Of Cure Process Of Epoxy Prepreg, Liangfeng Sun

LSU Doctoral Dissertations

The cure process of epoxy prepreg used as composite pipe joints was studied by means of differential scanning calorimetry (DSC), Bohlin Rheometer and other techniques. Isothermal DSC measurements were conducted between 110 and 220 oC, at 10 oC intervals. The results show that the complete cure reaction could be achieved at oC. The isothermal cure process was simulated with the four-parameter autocatalytic model. Except in the late stage of cure reaction, the model agrees well with the experimental data, especially at high temperatures. To account for the effect of diffusion on the cure rate, a diffusion factor was introduced into …

Markov Models To Estimate And Describe Survival Time And Experience In Cohorts With High Euthanasia Frequency, Giselle Louise Hosgood Jan 2002

Markov Models To Estimate And Describe Survival Time And Experience In Cohorts With High Euthanasia Frequency, Giselle Louise Hosgood

LSU Doctoral Dissertations

Unique to survival analysis of veterinary clinical data is classification of observations from euthanized animals. The first study highlighted limitations of Kaplan-Meier product limit analysis (KM) of veterinary clinical data. Three data sets with different outcome proportions (alive, lost-to-follow-up, dead due to disease, dead due to other, euthanized due to disease, euthanized due to other) were used. Different classifications of observations from euthanized animals caused inconsistent conclusions of significant differences between strata within data sets. At times, ranking of median survival time estimates for strata was reversed. The KM was found inappropriate to evaluate observations from euthanized animals. This finding, …

Hydrodynamics And Freshwater Diversion Within Barataria Basin, Dongho Park Jan 2002

Hydrodynamics And Freshwater Diversion Within Barataria Basin, Dongho Park

LSU Doctoral Dissertations

In order to understand the physical processes in the Barataria estuary, a previously developed two-dimensional, depth-integrated hydrodynamic model is applied to simulate estuarine processes. The equations for conservation of mass and momentum predict specific physical processes when forced by tidal and salinity variations at the open boundaries, wind forcing patterns, precipitation and evaporation over the model domain, and freshwater runoff as point sources. This study is focused on examining the impact of freshwater dispersion from the freshwater sources. Thus, a hydrologic model was developed to estimate runoff. Furthermore grid size was reduced, a new advective code added, and baroclinic effects …

The Role Of Initial Coping Strategies On Subsequent Appointment Attendance In Individuals With Hiv: A Longitudinal Analysis, Deann Morris Johnson Jan 2002

The Role Of Initial Coping Strategies On Subsequent Appointment Attendance In Individuals With Hiv: A Longitudinal Analysis, Deann Morris Johnson

LSU Doctoral Dissertations

With advances in HIV treatment regimens, HIV has become a treatable chronic illness that requires extensive clinical management (Kelly, Otto-Salaj, Sikkema, Pinkerton, & Bloom, 1998). Nonadherence to HIV medical regimens is a primary reason for treatment failure. HIV medication regimens are complicated and require extensive time and effort from the patient (Friedland & Williams, 1999). Since the effectiveness of HIV medication regimens can be severely limited by poor adherence, much research has been conducted regarding the influence of psychosocial factors in adherence. However, this research has primarily focused on medication adherence and has not investigated psychosocial aspects associated with other …

A Qualitative Analysis Of Figural Memory Performance In Persons With Epilepsy, Deborah Schrager Hoffnung Jan 2002

A Qualitative Analysis Of Figural Memory Performance In Persons With Epilepsy, Deborah Schrager Hoffnung

LSU Doctoral Dissertations

This study examined nonverbal memory in patients with intractable temporal lobe epilepsy (TLE) on a figural reproduction task, the Rey-Osterrieth Complex Figure (ROCF). The Boston Qualitative Scoring System (BQSS) was used to examine whether qualitative features of ROCF performance could discriminate between those with right and left TLE. As predicted, seizure groups did not differ on a standard quantitative scoring system for the ROCF. Contrary to prediction, the right TLE group did not perform more poorly on BQSS measures of quality or organization, and they did not have greater difficulty recalling the figure after a delay. There was a trend …

Factors Influencing The Efficacy Of Delayed Auditory Feedback In Treating Dysarthria Associated With Parkinson's Disease, Paul Gerard Blanchet Jan 2002

Factors Influencing The Efficacy Of Delayed Auditory Feedback In Treating Dysarthria Associated With Parkinson's Disease, Paul Gerard Blanchet

LSU Doctoral Dissertations

Parkinson's disease patients exhibit a high prevalence of speech deficits including excessive speech rate, reduced intelligibility, and disfluencies. The present study examined the effects of delayed auditory feedback (DAF) as a rate control intervention for dysarthric speakers with Parkinson's disease. Adverse reactions to relatively long delay intervals are commonly observed during clinical use of DAF, and seem to result from improper "matching" of the delayed signal. To facilitate optimal use of DAF, therefore, clinicians must provide instruction, modeling, and feedback. Clinician instruction is frequently used in speech-language therapy, but has not been evaluated during use of DAF-based interventions. Therefore, the …

Occurrence Of Degenerative Joint Disease In The Radius: Analysis Of Skeletal Remains From The Poole-Rose Ossuary, Mirenda Ann Parks Jan 2002

Occurrence Of Degenerative Joint Disease In The Radius: Analysis Of Skeletal Remains From The Poole-Rose Ossuary, Mirenda Ann Parks

LSU Master's Theses

This study focuses on radii excavated from the Poole-Rose ossuary and analyzes the occurrence and patterning of degenerative joint disease (DJD) on the proximal and distal joint surfaces. The Poole-Rose ossuary, located in eastern Ontario, is dated to A.D. 1550 +/- 50. The Poole-Rose population, dating to the Late Woodland period, were agricultural in their subsistence activities. The disarticulated patterning of the skeletal remains suggests this site was associated with the “Feast of the Dead,” a mass interment burial ceremony. This ceremony took place about every eight to twelve years. Frequencies of lipping, porosity, and eburnation were reported in degree …

In Defense Of Malingering: A Cautionary Note, Dennis R. Dixon Jan 2002

In Defense Of Malingering: A Cautionary Note, Dennis R. Dixon

LSU Master's Theses

The simulation and exaggeration of job related injury symptoms is a significant problem in the Workers' Compensation system. The result of simulation and exaggeration is the inappropriate allotment of financial resources to workers whose actual injuries do not warrant such compensation. Psychology as a field has done much research in the past years to address the detection of malingering. Most of that focus has viewed malingering behavior as a personal choice, as well as being indicative of a character flaw. However, the degree to which external factors such as work conditions increase the likelihood of an individual malingering has received …

Adoption Of Best Management Practices In The Louisiana Dairy Industry, Noro C. Rahelizatovo Jan 2002

Adoption Of Best Management Practices In The Louisiana Dairy Industry, Noro C. Rahelizatovo

LSU Doctoral Dissertations

The traditional view of the agricultural community as a good steward of the environment has been challenged by increasing concerns about the complex relationship between agricultural production activities and environmental quality. Agriculture provides a large range of products to satisfy human needs. It has also been singled out as major source of water pollution. Largely improved surface water quality has been assessed in the U.S. since the enactment of the Clean Water Act. However, efforts to reduce water pollution continue, targeting discharges from identifiable sources of water pollution and diffused discharges from nonpoint sources. Agricultural producers are encouraged to voluntarily …

Methylation Of Adenine In The Nuclear Dna Of "Tetrahymena" Is Internucleosomal And Independent Of Histone H1, Kathleen M. Karrer, Teresa Ann Van Nuland

Biological Sciences Faculty Research and Publications

There are about 50 copies of each chromosome in the somatic macronucleus of the ciliated protozoan Tetrahymena. Approximately 0.8% of the adenine residues in the macronuclear DNA of Tetrahymena are methylated to N6-methyladenine. The degree of methylation varies between sites from a very low percentage to >90%. In this study a correlation was found between nucleosome positioning and DNA methylation. Eight GATC sites with different levels of methylation were examined. There was a direct correlation between the degree of methylation and proximity to linker DNA at these sites. Although methylation occurs preferentially in linker DNA, the patterns …

Beta-Galactosidase As A Marker Of Ischemic Injury And A Mechanism For Viability Assessment In Porcine Liver Transplantation., Shawn D. St Peter, Charles J. Imber, Inigo Lopez De Cenarruzabeitia, James Mcguire, Tim James, Richard Taylor, Peter J. Friend

Manuscripts, Articles, Book Chapters and Other Papers

Glycohydrolases are a group of enzymes contained predominantly within lysosomes, which are released during Kupffer cell activation or death. One of these, beta-galactosidase, has been proposed as a marker of ischemia-reperfusion injury in the liver because Kupffer cell activation represents a primary event in the injurious reperfusion cascade. In this study, we compared B-galactosidase with more traditional indicators of liver injury and function in a porcine model of liver preservation. Porcine livers were allocated into two groups: group C (n = 5), preserved in University of Wisconsin solution by standard cold storage for 24 hours, and group W (n = …

Discrimination Of Cardiac Health And Disease By Assessment Of Heart Rate Variability: Wavelet Vs. Fast Fourier Transformation, Jusonda Leray Derouen Jan 2002

Discrimination Of Cardiac Health And Disease By Assessment Of Heart Rate Variability: Wavelet Vs. Fast Fourier Transformation, Jusonda Leray Derouen

LSU Master's Theses

The autonomic nervous system (ANS) modulation of the heart is of clinical importance because of its relevance to risk of life threatening arrhythmic events. Decomposition of heart rate variability (HRV) has been used to quantify ANS control of the heart. The traditional method for frequency analysis has involved the use of fast Fourier transformation (FFT). However, heart rate data typically violate assumptions of the FFT. Therefore, the assessment of HRV may benefit from other, potentially more suitable, mathematical approaches. For example, the discrete wavelet transformation (DWT) appears to have promise with respect to its ability to discriminate between healthy and …
