Locus-Specific Detection Of Hla-Dq And -Dr Antigens By Antibodies Against Synthetic N-Terminal Octapeptides Of The Β Chain, Thomas Deufel, Anne Grove, Hans Kofod, Åke Lernmark

Faculty Publications

Antibodies against synthetic peptides representing the class-II antigen HLA-DR and -DQ β chain N-terminal sequences were prepared in rabbits. The two octapeptides only share two amino acids and enzyme-linked immuno-assays showed the antisera only to bind to its own antigen. Both peptide antisera detected a 29 kDa component in immunoblots of Raji and AL-34 cell plasma membrane proteins separated by SDS gel electrophoresis. The binding of either N-terminal peptide antiserum was selectively inhibited only by the peptide used as antigen. Indirect immunofluorescence.analysis by flow cytofluorometry showed specific surface immunofluorescence in 1:100-1:1000 dilutions in lymphoblastoid and blood mononucleated cells. In the …

The Azido[14C]Atrazine Photoaffinity Technique Labels A 34-Kda Protein In Scenedesmus Which Functions On The Oxidizing Side Of Photosystem Ii, James G. Metz, Terry M. Bricker, Michael Seibert

Faculty Publications

We have used azido[14C]atrazine to photoaffinity label thylakoids from wild-type (WT) Scenedesmus and a mutant, LF-1, which is blocked on the oxidizing side of photosystem II (PS II). One protein is labeled in each case, at 34 kDa in the WT and 36 kDa in LF-1. Previous comparison of the WT with LF-1 had been used to assign a PS II donor side function to the 34-kDa protein. These results suggest that this photoaffinity technique does not label the herbicide-binding protein involved in electron transfer on the reducing side of PS II. © 1985.

Water Quality Dynamics In Commercial Crawfish Ponds And Toxicity Of Selected Water Quality Variables To Procambarus Clarkii, Thomas Michael Hymel

LSU Historical Dissertations and Theses

Water quality in five southern Louisiana commercial crawfish (Procambarus clarkii and P. acutus acutus) ponds was monitored from November 1982 through May 1983. Two ponds were planted with rice (Oryza sativa) and three ponds had volunteer terrestrial and semi-aquatic vegetation as crawfish forage.

Water quality was poorest in November, April, and May when water temperatures exceeded 18"C. However, only dissolved oxygen (DO) attained concentrations low enough (<1.0 mg/liter) to be acutely toxic to crawfish. Free carbon dioxide (CO2) attained levels (12.0 mg/liter) that could potentially harm crawfish during periods of low DO (<2.0 mg/liter). The temperature, pH, free CO2, nitrate, total phosphorus, biochemical oxygen demand (BOD), chlorophyll a, total hardness, and total alkalinity did not differ significantly among rice ponds and ponds with volunteer vegetation. The DO, nitrite, total nitrogen, and chemical oxygen demand (COD) were highest in rice ponds (P<0.05). The soluble inorganic phosphorus (SIP) and conductivity were highest in ponds with volunteer vegetation (P<0.05).

Free CO2, SIP, conductivity, and total alkalinity levels were positively correlated with an increase in macrophytic biomass (P<0.10). Nitrite, total nitrogen, COD, BOD, turbidity, temperature and DO decreased with increased vegetative biomass. Crawfish catch was positively correlated with total ammonia, BOD, COD, and water temperature, and negatively correlated with total phosphorus, total nitrogen, SIP, total alkalinity, and DO.

The toxicity of hydroxyl and hydrogen ions (i.e., pH), ammonia, and nitrite to juvenile P. …

Distributional Analysis For Discontinuous Fields, R. Estrada, R. P. Kanwal

Faculty Publications

The jump conditions that hold across singular surfaces for the fields having step function discontinuities do not, in general, apply if these surfaces themselves carry concentrated fields. In this note, the general situation when the surfaces of discontinuity carry multilayers and deform as they propagate is discussed. Formulas are presented for the first and second derivatives for these multilayers. © 1985.

Modification Of Rice Flour And Its Potential Use In The Food Industry., Samir Sideek Alhusaini

LSU Historical Dissertations and Theses

Rice flour was modified with either 0.1, 1.0 and 5.0% acetic or succinic anhydride for 1, 6 and 18 hr under basic conditions. The pH was maintained above 7.0 using either sodium hydroxide or sodium carbonate. The results showed that modified rice flours had lower fat content as compared with the unmodified rice flour (control). The type of anhydride significantly influenced the fat content of rice flour. Ash content of rice flour increased significantly due to the anhydride concentrations and alkali type. Significant differences were also found in the protein content of modified rice flours due to the use of …

Assessment Of Dairy Product Quality Utilizing Bacterial Enumeration And Metabolite Detection., Jay Russell Bishop

LSU Historical Dissertations and Theses

A study was conducted to investigate the use of bacterial numbers and metabolites as estimators of the potential shelf-life of perishable dairy products, i.e., whole milk, skim milk and cottage cheese. The study was conducted in three phases. In the first phase, a method of impedance detection was performed at two incubation temperatures (18(DEGREES)C and 21(DEGREES)C), and its ability to estimate shelf-life of 100 commercially purchased milk samples compared to standard plate count (SPC), psychrotrophic bacteria count (PBC), modified psychrotrophic bacteria count (mPBC) and Mosely keeping quality test (MSPC). MSPC appeared to possess an adequate relationship to shelf-life (R = …

The Interaction Of Conceptual Tempo And Modeling On Motor Performance (Learning Style)., Shirley Devard Brown

LSU Historical Dissertations and Theses

This experiment was designed to examine the effects of conceptual tempo and modeling on performance of a serial motor task. There were 48 subjects, 10- and 11-years old males and females, classified as impulsive or reflective. Subjects were randomly assigned to one of three modeling groups or a control group. The modeling strategies included: silent-model, verbal-model and verbal-model with self-instruction. The task was a motor skill obstacle course in which both speed and errors were scored. Data were analyzed by a 2 x 4 (Cognitive Style x Model Type) MANOVA with the number of trials to criterion, the average number …

The Effects Of Selected Demographic Variables And Gender-Role Identity On Premarital Sexual Permissive Attitudes (Androgyny, Masculine, Feminine)., Carol Sue Campbell

LSU Historical Dissertations and Theses

The purpose of this study was to explore the relationships between: (a) socialization experiences and gender-role identity, (b) socialization experiences and premarital sexual permissive attitudes, and (c) gender-role identity and premarital sexual permissive attitudes using a causal model. Data were gathered from a random sample of 571 college students. The instrument consisted of standard background questions, the Bem Sex-Role Inventory, a religiosity scale, and the Reiss' Premarital Sexual Permissiveness Scale. A t-test was used to test the differences between the means of males and females concerning gender-role identity and premarital sexual permissiveness. Males were found to possess higher levels of …

Response Transfer In Biofeedback Training., Lynn Pendarvis Clemow

LSU Historical Dissertations and Theses

The physiological effects and processes of biofeedback procedures are important issues in relaxation training. The purpose of this study was to assess the extent of cross-system generalization and the processes by which it may occur. Specifically, do different biofeedback tasks produce different patterns of response across systems and, are the physiological processes different for each biofeedback task, or are they similar processes in all tasks? Forty-eight volunteers participated in three one-hour sessions and randomly assigned to one of four groups as follows; (1) increase hand-temperature, (2) decrease frontalis-EMG, (3) decrease hand-temperature, and (4) control. Subjects received training as indicated in …

Karyology Of Lower Teleost Fishes (Clupeiformes, Taxonomy, Elopiformes, Phylogeny)., Albert John Doucette Jr

LSU Historical Dissertations and Theses

Karyotypes of nine species (Megalops atlanticus, Elops saurus, Brevoortia patronus, B. smithi, B. tyrannus, Dorosoma cepedianum, D. petenense, Harengula clupeola, and Anchoa mitchilli) and one hybrid (B. smithi x B. tyrannus) of teleost fishes revealed diploid complements ranging from 28 to 50 chromosomes and comprised of uniarmed elements or combinations of uniarmed and small and large biarmed elements. The occurance of large metacentric-submetacentric chromosomes was usually associated with a reduction in total chromosome number suggesting fusion events in the evolution of karyotypes from ancestral complements with 48 to 52 acrocentrics. Information from karyotypes is used to characterize species, genera, and …

The Population Ecology And Nutrient Transport Of Gulf Menhaden In Fourleague Bay, Louisiana (Mortality, Growth, Feeding, Production, Migration)., Linda Ann Deegan

LSU Historical Dissertations and Theses

An ecological study of the young-of-the-year of three year-classes of gulf menhaden (Brevoortia patronus) was conducted from July 1981 to December 1983 in Fourleague Bay, Louisiana. This study documented gulf menhaden population ecology and the importance of gulf menhaden in the nutrient and energy balance of estuaries. Young-of-the-year gulf menhaden immigrated in winter and moved to tidal creeks and ponds, where they remained until midsummer. They then moved into open bays, where they remained until the fall. This migration pattern coincides with sequentially available, but spatially separate, productivity peaks in marsh and open bays. In the fall, they emigrated to …

The Effects Of Performance Standards On Behavior Patterns And Motor Skill Achievement In Children (Goals, Time-On-Task)., Rosaland Veatrice Edwards

LSU Historical Dissertations and Theses

The effect of individual performance standards on the relationship between selected process variables and achievement for students in elementary physical education classes was investigated. The subjects were 78 fourth grade and 80 fifth grade students from eight classes in two elementary schools. Two fourth and fifth grades received standards and two fourth and fifth grades did not. A one week experimental teaching unit was used. A Solomon 4-group design was used in an effort to determine if there was a pretest effect. The data were analyzed in a Treatment (standard-no standard) x Pre (pre-no pretest) x sex (male-female) x grade …

Some Results About Value Sets Of Quadratic Forms Over Fields., David Litton Foreman

LSU Historical Dissertations and Theses

In 1979, Solow defined the square class invariant of a quadratic form q over a field F to be a function from the square classes of F into the integers. For each square class of F, this function indicates the maximum number of coefficients in all diagonalized quadratic forms equivalent to q that lie in that square class. The intent of Chapter I is to determine the fields over which the square class invariant classifies quadratic forms. It will be proved that if the level of the field is at most two and if the square class invariant classifies the …

Metal Ion, Protein, Phytic Acid Interactions., Elaine Thompson Champagne

LSU Historical Dissertations and Theses

Insight into the mineral, protein, phytate relationships in rice bran was gained by examining the solubility behavior of these components. Solubility profiles of the phosphorus and nitrogen components as a function of pH did not correspond, except in the pH 1.0-2.0 range. This is evidence that association between protein and phytate only occurred in this low pH range. Potassium, magnesium, and calcium solubilities as a function of pH corresponded to those of the phytic acid salts of these minerals. Soluble magnesium and potassium phytates were isolated on Sephadex G-25-50 and identified by ICP, confirming their presence in rice bran. The …

Molecular Studies Of Thamnophiine Snakes., Robin Lawson

LSU Historical Dissertations and Theses

Variation in alleles at gene loci encoding proteins was used to determine zoogeographic and evolutionary differentiation in thamnophiine snakes. Differentiation among populations within a species, among species within a genus, and among genera was investigated. In the southern banded water snake, Nerodia fasciata, analysis by F-statistics and genetic distances of allele frequencies indicated that extensive differentiation has occurred between those forms adapted to a saltwater environment (N. f. clarkii and N. f. compressicauda) and those adapted to a freshwater environment (N. f. fasciata, N. f. confluens, and N. f. pictiventris). Habitat disturbance is imputed as the causal agent in the …

The Biology Of Egg Production In The House Cricket, Acheta Domesticus L., Craig William Clifford

LSU Historical Dissertations and Theses

Oogenesis commenced on day 3 (day 0 = adult ecdysis) in Acheta domesticus L., which, based on degeneration of the flight muscles, was approximately when juvenile hormone was released. Starvation did not prevent the onset of oogenesis, although egg production was greatly reduced. Virgin females did not oviposit and the oviducts filled with eggs by day 15. Compaction appeared to be a factor limiting oogenesis. The digestive tract was compressed and feeding reduced, which might be the primary factors terminating oogenesis. The concentration of juvenile hormone esterase (JHE) did not change as virgins filled with eggs, which indicated that JHE …

Inheritance Of Resistance To Sheath Blight In Long Grain Rice (Genetics, Fungus Disease)., Mamadou Goita

LSU Historical Dissertations and Theses

The inheritance of resistance to the sheath blight disease of rice (Oryza sativa L.), caused by Rhizoctonia solani Kuhn, was studied using as parent lines four susceptible commercial varieties--Lebonnet, Labelle, Starbonnet and Leah, and three resistant lines: L201, RU7902185 and RU7902191. The parental lines, F(,2) and F(,3) progeny of each cross were inoculated when the seedlings were 35 days old using the isolate LR172, and then kept in a humidity chamber for two weeks. The infection level of each plant was evaluated using a 0-9 rating system where 0 indicates no symptoms and 9 indicates the most severe infection. Infection …
