The Alkaloids Of Erythrina: Clonal Evaluation And Metabolic Fate., Lori Denise Payne Jan 1991

The Alkaloids Of Erythrina: Clonal Evaluation And Metabolic Fate., Lori Denise Payne

LSU Historical Dissertations and Theses

The foliage of thirteen genetic clones of the nitrogen-fixing trees Erythrina berteroana, E. poeppigiana and E. costarricensis growing under similar environmental conditions in the Latin American Nitrogen Fixing Tree Arboretum, CATIE, Turrialba, Costa Rica, was evaluated by gas chromatography/mass spectrometry for toxic alkaloid content. The major alkaloid identified was $\beta$-erythroidine, a naturally derived drug used in the 1950s and 1960s as a neuromuscular blocking agent in surgery and electroshock treatments. Other alkaloids identified were $\alpha$-erythroidine, erybidine, erythraline, erysodine, oxo-$\beta$-erythroidine and several previously undescribed compounds. There was a difference of more than two orders of magnitude in the $\beta$-erythroidine concentration between …

A Survey Of Discrepancies Among Solo Parts Of Editions And Manuscripts Of Carl Maria Von Weber's Concerto No. 1 In F Minor, Op. 73., Ronnie Everett Wray Jan 1991

A Survey Of Discrepancies Among Solo Parts Of Editions And Manuscripts Of Carl Maria Von Weber's Concerto No. 1 In F Minor, Op. 73., Ronnie Everett Wray

LSU Historical Dissertations and Theses

This monograph presents a study of the interpretation of Carl Maria von Weber's Concerto No. 1 in F minor, Op. 73 for clarinet and orchestra. Twelve published editions are examined and compared with the two extant manuscript copies from the Library of Congress and the Deutsche Staatsbibliothek. Because of Weber's apparent haste or carelessness in committing music to paper, and because of certain traditions in performance, a number of attempts have been made to edit this concerto. Given the large number of editions available to the clarinetist and the varied interpretations they present, it would be difficult to determine the …

The Clan Of Toil: Piney Woods Labor Relations In The Trans-Mississippi South, 1880-1920. (Volumes I-Iii)., John Reed Tarver Jan 1991

The Clan Of Toil: Piney Woods Labor Relations In The Trans-Mississippi South, 1880-1920. (Volumes I-Iii)., John Reed Tarver

LSU Historical Dissertations and Theses

Lumber boomed in the Reconstructed South, an industrial binge that, by 1920, changed the landscape, first removing the forest then replacing its subsistence economy with consumerism. Men with money made fortunes in lumber. West of the Mississippi and south of the Missouri, it became a bonanza by 1880. Within these boundaries, black and white farmers and field hands sought "public work" in sawmills and log fronts. Most were unskilled. Steam power changed their lives, although all did not respond alike. They kept their folk ways, consistent with the new industry, despite their bondage to machines. Although most workers voluntarily entered …

A Study Of Metacognitive Skill As Influenced By Expressive Writing In College Introductory Algebra Classes., Naomi Barbara R Allen Jan 1991

A Study Of Metacognitive Skill As Influenced By Expressive Writing In College Introductory Algebra Classes., Naomi Barbara R Allen

LSU Historical Dissertations and Theses

The quality of mathematics education has become a major concern to mathematics educators. As a result, increased attention is being given to identifying the abilities that underlie competent performance. An outcome of this effort is an increasing belief that the development of metacognitive skills is an essential component of proficient mathematics performance. Writing, because it promotes reflective thinking, is believed to be the vehicle for this development. Writing in the mathematics classroom has previously received anecdotal support for its benefits to the learner and to the instructor, and limited quantitative benefits in problem-solving ability toward mathematics. This study examined the …

Timed Daily Thermopulses Alter The Circadian Hormonal Regulation Of Glucose And Lipid Metabolism., Christopher Joseph De Souza Jan 1991

Timed Daily Thermopulses Alter The Circadian Hormonal Regulation Of Glucose And Lipid Metabolism., Christopher Joseph De Souza

LSU Historical Dissertations and Theses

Studies were made in Syrian hamsters and Holtzman rats to examine roles for circadian rhythms in the control of body fats stores. Baseline and circadian rhythms of plasma insulin varied seasonally in the Syrian hamster. Baseline concentrations of the hormone were almost 4 times greater in scotosensitive female hamsters held on short daily photoperiods when they were fat than in lean animals at other seasons and other photoperiodic schedules. Additionally, plasma insulin levels in fat hamsters, but not in lean animals, peaked at light onset when lipogenic responsiveness to insulin is greatest. The circadian rhythms of plasma insulin are not …

Partial Sequence And Characterization Of A Growth Hormone Gene Of The Red Drum (Sciaenops Ocellatus)., Carol Marie Dorworth

LSU Historical Dissertations and Theses

A growth hormone (GH) gene was isolated from nuclear DNA of the red drum (Sciaenops ocellatus). Synthetic oligonucleotides were synthesized based on published cDNA sequences of other perciform fishes. Polymerase chain reaction (PCR) methodology was employed to amplify a nucleotide sequence extending from the 5$\sp\prime$ end of intron I to 15 bases upstream of the 3$\sp\prime$ end of exon VI of the GH gene. Amplified DNA was cloned into a phagemid sequencing vector. Clones were sequenced. Computer analysis of sequence data was used to determine the internal gene arrangement of exons and introns. Homologies of the nucleotide and deduced amino …

Ruminal Distribution And Utilization Of Zinc And Magnesium As Influenced By Dietary Source And Energy Level., Donald Wayne Kennedy Jan 1991

Ruminal Distribution And Utilization Of Zinc And Magnesium As Influenced By Dietary Source And Energy Level., Donald Wayne Kennedy

LSU Historical Dissertations and Theses

Steers fed a conventional diet were utilized to determine the effects of various Zn supplements on ruminal distribution of Zn. Treatments consisted of a basal (B) diet (no Zn supplementation) and B supplemented with equal parts of Zn from either a polysaccharide complex of Zn (PC-Zn) or zinc oxide (ZnO). Samples were fractionated into four fractions: a cell-free fraction, a particulate fraction and two microbial fractions. After PC-Zn or ZnO were dosed intraruminally, relative distribution of Zn from each Zn source within each fraction was evaluated up to 8 h postdosing. Cannulated growing lambs were used to study the effects …

Ecology Of Wintering Redheads (Aythya Americana) On The Lower Laguna Madre, Texas., Christine Anne Mitchell Jan 1991

Ecology Of Wintering Redheads (Aythya Americana) On The Lower Laguna Madre, Texas., Christine Anne Mitchell

LSU Historical Dissertations and Theses

Data on behavior, distribution, and food and habitat requirements of wintering redhead ducks (Aythya americana) were collected during 2.5 winters on the lower Laguna Madre, Texas, between 1987 and 1989. Migrating redheads began arriving on the lower Laguna Madre with frontal passages in early October. They initially congregated in the central portion of the lagoon, and the majority remained there through the winter. As winter progressed, flocks dispersed to other parts of the Laguna Madre. Ninety-five percent of redhead flocks were above stands of monotypic shoalgrass (Halodule wrightii) vegetation, their primary food source. Redheads fed intermittently throughout the day; most …

Oxidative Chemical Transformations Of Sesquiterpene Lactones., Howard Gordon Pentes Jan 1991

Oxidative Chemical Transformations Of Sesquiterpene Lactones., Howard Gordon Pentes

LSU Historical Dissertations and Theses

Oxidative chemical transformations of sesquiterpene lactones have been carried out to determine the effect these changes have on the biological activities of these derivatives. Vacuum liquid chromatography was used extensively to isolate the sesquiterpene lactones used for these synthetic transformations. Costunolide and dehydrocostuslactone were isolated from Costus Resinoid (Saussurea lappa) and dihydroparthenolide was isolated from Ambrosia artemisiifolia. The enolate oxidations of sesquiterpene lactones with oxygen and (camphorylsulfonyl)oxaziridine have been investigate. Enolate oxidations of sesquiterpene lactones with oxygen generate low yields of both 11$\alpha$- and 11$\beta$-hydroxylactones. The yields of enolate oxidations with (camphorylsulfonyl)oxaziridine are much improved (over oxygen) and the reaction …

Toward A Phenomenology Of Curriculum: The Work Of Max Van Manen And T. Tetsuo Aoki., Robert Kent Brown

LSU Historical Dissertations and Theses

In this study an attempt was made at understanding contemporary thought and application of phenomenological research to the field of curriculum and instruction. More specifically, it sought to identify a place and need for a methodology in curriculum research that exposes and clarifies the dynamics of pedagogy as a result of investigating the existential/ontological nature of pedagogical activity. In accomplishing this, the works of two major North American phenomenological curriculum theorists, T. Tetsuo Aoki and Max van Manen were examined. The work of these two significant contemporary curriculum theorists was used due to the international recognition their seminal phenomenologically oriented …

Metabolism And Mutagenicity Of Dinitropyrenes: Effect Of Chronic Ethanol Ingestion And Aroclor 1254 Pretreatment., Antal Karl Hajos Jan 1991

Metabolism And Mutagenicity Of Dinitropyrenes: Effect Of Chronic Ethanol Ingestion And Aroclor 1254 Pretreatment., Antal Karl Hajos

LSU Historical Dissertations and Theses

The nitroreduction of three potently mutagenic dinitropyrene (DNP) isomers by liver cytosol from Aroclor-1254-pretreated rats was studied. NAD(P)H-quinone oxidoreductase (NQOR) is increased 12- to 24-fold by this treatment and resulted in up to 5-fold induction of cytosolic DNP-nitroreductase as compared to chow-fed controls. Upon purification, NQOR activity towards menadione coeluted with C-nitroso- and 1,6-DNP nitroreductase activity. Purified NQOR catalyzed NAD(P)H-dependent reduction of all DNP, displayed the same isomer specificity as did cytosol and increased the mutagenicity of all DNP in the Ames assay up to 3-fold. In TA98NR, a strain deficient in nitroreductase, only the mutagenicity of 1,3-DNP was markedly …

Pcr Amplification Of Chlamydial Momp Genes: Detection, Sequence Analysis And Evolution., Bernhard Kaltenboeck Jan 1991

Pcr Amplification Of Chlamydial Momp Genes: Detection, Sequence Analysis And Evolution., Bernhard Kaltenboeck

LSU Historical Dissertations and Theses

Sensitive detection and differentiation of the bacterial genus Chlamydia (C.) was accomplished using the polymerase chain reaction (PCR), and phylogenetic relationships among chlamydiae were inferred from DNA sequences of amplified major outer membrane protein (MOMP) genes. DNA of strains of C. psittaci was efficiently amplified using primers homologous to nontranslated regions of the MOMP genes (ompA). Portions of these reactions were reamplified using one different primer specific for an internal ompA sequence. Primary amplification products were differentiated by restriction analysis. Degenerate, inosine containing oligonucleotide primers homologous to terminal translated regions amplified DNA fragments of all chlamydial MOMP genes. Partial ompA …

Conceptus-Derived Immunosuppressive Factors And Their Role In Fetal Allograft Protection., Terri Lynn Roth Jan 1991

Conceptus-Derived Immunosuppressive Factors And Their Role In Fetal Allograft Protection., Terri Lynn Roth

LSU Historical Dissertations and Theses

The role of conceptus-derived immunosuppressive factors in protecting the fetal allograft was investigated by first examining the immunosuppressive activity derived from ovine, caprine and hybrid conceptus trophoblast tissue. Medium conditioned by 20 day-old conceptus trophoblast tissue from each species suppressed sheep and goat lymphocyte proliferation (P $$.05) between the immunosuppressive effects of the three media on either sheep or goat lymphocytes. In subsequent studies, horse conceptus-conditioned medium (HCCM) derived from embryos at days 9, 15 and 26 of gestation, suppressed mitogen-stimulated horse lymphocytes (P $<$.001). HCCM maintained its suppressive activity following heating and repeated freeze-thawing. Using microconcentrator centrifugation, it was determined that the suppressor factor(s) was $>$100,000 MW. HCCM was tested in donkey and goat lymphocyte cultures and proved capable of …

Methyl Oleate Ozonides In Aqueous Micelles: Formation, Stability, And Initiation Of Lipid Peroxidation, And, Relative Antioxidant Efficiencies In Aqueous Micelles Of Anionic And Cationic Surfactants., Mingdan Wu Jan 1991

Methyl Oleate Ozonides In Aqueous Micelles: Formation, Stability, And Initiation Of Lipid Peroxidation, And, Relative Antioxidant Efficiencies In Aqueous Micelles Of Anionic And Cationic Surfactants., Mingdan Wu

LSU Historical Dissertations and Theses

Ozonation of methyl oleate has been shown for the first time to form ozonides in aqueous micelles of sodium dodecyl sulfate (SDS) and in L-$\alpha$-distearoyl-phosphatidylcholine (DSPC) liposomes. The total yield of ozonides in 0.02 M SDS micelles exposed to 26 ppm ozone at pH 7.4 and 22$\sp\circ$C is 11.1%. This 11.1% consists of 7.5% of the normal ozonide (MOO2), ca. 4.2% of trans-isomer and ca. 3.3% of cis-isomer, and the rest 3.6% is accounted for by the cross ozonides (MOO1 and MOO3). Regarding the hydrolytic stability of the ozonides under physiologically relevant conditions (e.g., pH 7.4 and 37$\sp\circ$C), the half-lives …

An Investigation Of The Laryngeal System As The Resonance Source Of The Singer's Formant., Rebecca Finley Detweiler Jan 1991

An Investigation Of The Laryngeal System As The Resonance Source Of The Singer's Formant., Rebecca Finley Detweiler

LSU Historical Dissertations and Theses

Since its introduction in 1974, Johan Sundberg's model of the laryngeal system as the resonance source of the singer's formant (Fs) has gained wide acceptance. There have heretofore been no studies directly testing its validity in vivo. The purpose of this study was to undertake a direct test of that hypothesis, utilizing as subjects professional male singers trained in the western Classical tradition. The vocal behaviors of three trained singer-subjects were evaluated during modal and pulse register phonation via magnetic resonance imaging (M.R.I.), strobolaryngoscopy, and acoustical analysis. Dr. Sundberg's hypothesis rests upon two premises: (1) that the laryngeal system is …

In Vitro Studies On Cigarette Smoke-Mediated Damage To Human Alpha-1-Proteinase Inhibitor., Mark Dennis Evans Jan 1991

In Vitro Studies On Cigarette Smoke-Mediated Damage To Human Alpha-1-Proteinase Inhibitor., Mark Dennis Evans

LSU Historical Dissertations and Theses

The effect, in vitro, of water soluble components of the particulate phase of cigarette smoke on the elastase inhibitory capacity (EIC) of human alpha-1-proteinase inhibitor ($\alpha\sb1$PI) is studied. Basic features of aqueous cigarette tar extract-mediated damage to $\alpha\sb1$PI are presented, as are mechanistic studies addressing the identities of damaging species and the nature of damage to $\alpha\sb1$PI. Aqueous cigarette tar extract (ACT) causes a slow loss of EIC, and retains this $\alpha\sb1$ PI damaging ability for hours. The damage to $\alpha\sb1$PI by ACT is dependent on its hydrogen peroxide content. Hydroxyl radicals or hypervalent metal species in the homogeneous phase …

Landscape Development And Coastal Wetland Losses In The Northern Gulf Of Mexico, R. Eugene Turner Feb 1990

Landscape Development And Coastal Wetland Losses In The Northern Gulf Of Mexico, R. Eugene Turner

Faculty Publications

The causes of the extensive (0.86%/yr; 288,414 ha/yr) and well documented dramatic and accelerating rate of coastal wetland loss in the northern Gulf of Mexico were investigated by an interdisciplinary university research team to discern the role of outer continental shelf development. The landscape changes and potential causal agents are emphasized herein. Natural driving factors include sea level rise and geological com- paction, which appear to remain constant this century, and sediment supply from the Mississippi River which has declined by 50%,since the 1950s. Man-made influences include hydrologic changes from river diversions, flood protection levees, an extensive canal and spoil …

Utilizing A Network Program Representation To Support Production System Program Development And Execution., Sally Jo Cunningham Jan 1990

Utilizing A Network Program Representation To Support Production System Program Development And Execution., Sally Jo Cunningham

LSU Historical Dissertations and Theses

This dissertation discusses modifications of the internal architecture of production systems that could significantly increase the execution performance of production system programs. This increased efficiency is achieved in part by modifications to the matching step of the execution cycle. Rather than checking all possible instantiations, we propose to consider only a small subset of the potential instantiations which are the "best candidates" for firing (according to the conflict resolution scheme). The increased execution efficiency provided by this matching strategy is compounded by modifying the OPS5 conflict resolution strategies. We propose a goal-directed (look-ahead) conflict resolution strategy which will still retain …

Factors Affecting The Foraging Ecology Of The Rock Snail Stramonita Haemastoma., Terry David Richardson Jan 1990

Factors Affecting The Foraging Ecology Of The Rock Snail Stramonita Haemastoma., Terry David Richardson

LSU Historical Dissertations and Theses

I examined how wave action and predators affect the feeding of the intertidal snail, Stramonita haemastoma. In laboratory wave simulators, the numbers of oysters eaten and tissue mass consumed were reduced compared to controls, but prey size selection was not affected. Handling times and profits (g dry tissue/handling time) of snails feeding on oysters did not differ between snails in wave simulators and controls. Over both treatments, small oysters reduced snail handling times but provided profits similar to that of large oysters. In contrast, field experiments showed that wave exposure was correlated with an increase in the number of oysters …

Factors Involved In Immune Modulation Of Bovine Leukemia Virus Infection., Wanda V. Pool

LSU Historical Dissertations and Theses

Bovine Leukemia Virus (BLV) is an exogenous type-C retrovirus which can induce an aleukemic (AL) stage, a persistent lymphocytotic (PL) stage, or a lymphosarcomatous (LS) stage in infected animals. After experimental infection with BLV, whole blood and serum samples were obtained from 12 holstein heifers for 103 weeks and used to correlate clinical signs (visual observation and white blood cell counts) with changes in humoral immune response (Agar gel immunodiffusion using envelope gp50 as primary antigen, and ELISA and Western immunoblots using whole BLV as antigen). Monoclonal antibodies against BLV envelope gp50 and gag p24 were produced to confirm reactivity …

Open And Closed Systems In Data Analysis Entropy., Hamid Reza Jafari Jan 1990

Open And Closed Systems In Data Analysis Entropy., Hamid Reza Jafari

LSU Historical Dissertations and Theses

This dissertation presents an efficient and integrated approach to data analysis. Entropy data analysis is an evolution of reconstructability analysis, which investigates the relationships between parts and wholes. The central theme of the dissertation is the development of a system to condense the information in a data set into a small number of parameters. The new system is called a k-system. k-system analysis goes beyond traditional data analysis in that it has the potentiality for changes to be made to a system; and the impact of these changes can be evaluated. k-system can be useful in designing and evaluating open …

Insulin Responsiveness In Skeletal Muscle Is Determined By Glucose Transporter (Glut4) Protein Level, M. Kern, J. A. Wells, J. M. Stephens, C. W. Elton, J. E. Friedman, E. B. Tapscott, P. H. Pekala, G. L. Dohm

Faculty Publications

Glucose transport in skeletal muscle is mediated by two distinct transporter isoforms, designated muscle/adipose glucose transporter (Glut4) and erythrocyte/HepG2/brain glucose transporter (Glut1), which differ in both abundance and membrane distribution. The present study was designed to investigate whether differences in insulin responsiveness of red and white muscle might be due to differential expression of the glucose transporter isoforms. Glucose transport, as well as Glut1 and Glut4 protein and mRNA levels, were determined in red and white portions of the quadriceps and gastrocnemius muscles of male Sprague-Dawley rats (body wt. approx. 250 g). Maximal glucose transport (in response to 100 nM-insulin) …
