Anatomy Of The Herpes Simplex Virus 1 Strain F Glycoprotein B Gene: Primary Sequence And Predicted Protein Structure Of The Wild Type And Of Monoclonal Antibody-Resistant Mutants, P. E. Pellett, K. G. Kousoulas, L. Pereira, B. Roizman Jan 1985

Anatomy Of The Herpes Simplex Virus 1 Strain F Glycoprotein B Gene: Primary Sequence And Predicted Protein Structure Of The Wild Type And Of Monoclonal Antibody-Resistant Mutants, P. E. Pellett, K. G. Kousoulas, L. Pereira, B. Roizman

Faculty Publications

In this paper we report the nucleotide sequence and predicted amino acid sequence of glycoprotein B of herpes simplex virus 1 strain F and the amino acid substitution in the domains of the glycoprotein B gene of three mutants selected for resistance to monoclonal antibody H126-5 or H233 but not to both. Analyses of the amino acid sequence with respect to hydropathicity and secondary structure yielded a two-dimensional model of the protein. The model predicts an N-terminal, 29-amino-acid cleavable signal sequence, a 696-amino-acid hydrophilic surface domain containing six potential sites for N-linked glycosylation, a 69-amino-acid hydrophobic domain containing three segments …

Comparison Of Drug Effects On Fixed‐Ratio Performance And Chain Performance Maintained Under A Second‐Order Fixed‐Ratio Schedule, Peter J. Winsauer, Donald M. Thompson, Joseph M. Moerschbaecher

Faculty Publications

In one component of a multiple schedule, pigeons were required to complete the same four‐response chain each session by responding sequentially on three identically lighted keys in the presence of four successively presented colors (chain performance). Food presentation occurred after five completions of the chain (i.e., after 20 correct responses). Errors, such as responding on the center or right key when the left was designated correct, produced a brief timeout but did not reset the chain. In the other component, responding on a single key (lighted white) was maintained by food presentation under a fixed‐ratio 20 schedule. In general, phencyclidine …

Host Responses To The Phenolic-Glycolipid-1 Antigen Of Mycobacterium Leprae (Elisa, Leprosy, Epidemiology, Armadillo, Human)., Richard W. Truman Jan 1985

Host Responses To The Phenolic-Glycolipid-1 Antigen Of Mycobacterium Leprae (Elisa, Leprosy, Epidemiology, Armadillo, Human)., Richard W. Truman

LSU Historical Dissertations and Theses

Antibody responses to the apparently species specific phenolic-glycolipid-1 (Phen-Gl-1) antigen of Mycobacterium leprae were examined in humans and armadillos using enzyme-linked immunosorbent assays (ELISA). Statistical definitions for the interpretation of positive and negative reactions were derived. A retrospective serological survey of armadillos indicated that leprosy in the wild armadillo is a naturally acquired zoonosis. Presently 12.5% of the armadillos in 2 parishes in south central Louisiana have detectable IgM antibodies to Phen-Gl-1. Approximately 2.7% of these histologically exhibit clinical disease. Antibodies were not detected in Florida armadillo sera. Variations in prevalence rates were noted, and may be due to environmental …

Social Skills Assessment For Mainstreamed Handicapped Students: The Discriminative Efficiency Of The Teacher Ratings Of Social Skills (Tross)., Frederick Lee Black Jan 1985

Social Skills Assessment For Mainstreamed Handicapped Students: The Discriminative Efficiency Of The Teacher Ratings Of Social Skills (Tross)., Frederick Lee Black

LSU Historical Dissertations and Theses

Until recently no time-efficient teacher rating scale of social skills has been available. With the development of the Teacher Ratings of Social Skills (TROSS; Gresham & Elliott, 1984) this gap has possibly been filled. Preliminary research on the scale has shown it to possess adequate reliability and validity (Clark, Gresham, & Elliott, 1985). Little is known yet, however, regarding the possible utility of the scale in discriminating among school-aged children of differing handicapping conditions. The present study examined the discriminative efficiency of the TROSS with a sample of 250 school-age children from four different groups: (a) Behavior Disordered, (b) Learning …

Modeling The Failure Time Distribution For Manufacturing And Retail Corporations Using Survival Analysis (Bankruptcy, Cox Model, Binary Response, Business)., George S. Karamessinis Jan 1985

Modeling The Failure Time Distribution For Manufacturing And Retail Corporations Using Survival Analysis (Bankruptcy, Cox Model, Binary Response, Business)., George S. Karamessinis

LSU Historical Dissertations and Theses

In the past the problem of financial distress has been investigated mainly through discriminant analysis and conditional response (logit, probit) techniques. With the use of such models, inference is made about the future status of a company as failure or non-failure conditional upon its observed financial attributes. Although response models (and discriminant models under certain assumptions) can be used to estimate the probability of failure of a firm as a function of its observed characteristics, neither group of techniques can provide estimates of the failure rate (hazard) of a population as a function of time. In certain situations, when the …

Alternative Regimes Of Common Property Exploitation For Manganese Nodules And Their Market Structure Impact., Akbar Barzegar Marvasti Jan 1985

Alternative Regimes Of Common Property Exploitation For Manganese Nodules And Their Market Structure Impact., Akbar Barzegar Marvasti

LSU Historical Dissertations and Theses

As a result of the technological and financial changes in the extraction of manganese nodules from the deep-seabed, the nodules have been recognized as an alternative source of minerals to land-based sources. The commercial interest in the extraction of the nodules is primarily for their nickel, cobalt, copper, and manganese. Three sources of uncertainty, however, have prevented involved consortia from entry into the actual production stage. These uncertainties are of a technological, economic, and legal nature. In spite of these difficulties, most experts maintain that the nodules are likely to be mined before the end of the century. The choice …

Influence Of Vegetation Manipulation And Selected Cultural Practices On Predation In Louisiana Sugarcane Ecosystems (Saccharum, Sorghum, Solenopsis, Spiders, Araneae)., Ahmed Daoud Ali

LSU Historical Dissertations and Theses

A 3-yr study on southeastern Louisiana sugarcane (Saccharum officinarum L. 'CP 65-357') revealed abundance and diversity of both ground- and foliage-associated predators and prey to be higher in weedy than in weed-free habitats. The imported fire ant (IFA), Solenopsis invicta Buren, major predator of the key insect pest, the sugarcane borer, Diatraea saccharalis (F.) , was more abundant in weedy (17 mounds/ha) than in weed-free (5 mounds/ha) habitats. Azinphosmethyl, commonly used for D. saccharalis control, decreased system stability through food web route disruption by decreasing coleopterans, phytophagous insects collectively, and spiders 51, 35, and 67%, respectively. Cane and sugar yields …

Allelochemicals From Soybean Affecting Pseudoplusia Includens (Walker) Biology And Pheromone From Chilo Plejadellus Zinken Mediating C. Plejadellus Sexual Behavior (Looper)., Porfirio Caballero

LSU Historical Dissertations and Theses

Extracts of foliage from the insect resistant soybean genotype PI227687 were bioassayed for activity against the soybean looper, Pseudoplusia includens (Walker), in feeding deterrency and growth inhibition tests. Dichloromethane extract had a pronounced deterrent effect on feeding, while petroleum ether and methanol extracts stimulated feeding. The water extract exhibited neutral activity. Flash chromatography of the dichloromethane extract yielded four fractions with moderate deterrent properties, one which was strongly deterrent, and one which was stimulative. Similar fractionation of the methanol extract yielded four fractions; one stimulated feeding, two deterred feeding, and one was neutral. Feeding P. includens larvae on artificial diet …

The Effect Of Muscle Contraction Headache Chronicity On Frontal Emg (Psychophysiology, Tension Headache)., Eleanor Belle Callon Jan 1985

The Effect Of Muscle Contraction Headache Chronicity On Frontal Emg (Psychophysiology, Tension Headache)., Eleanor Belle Callon

LSU Historical Dissertations and Theses

The hypothesis that frontal EMG levels measured by surface electrodes change as a function of the number of years of muscle contraction headache activity was tested. Three levels of muscle contraction headache chronicity ((GREATERTHEQ)20 years, (LESSTHEQ)10 years, and none) were examined under imagined stress and a quiz falsely presented as a measure of intelligence. The two stress conditions were counterbalanced across subjects. The three groups had 10 members each and were equivalent in age and subjects' ratings of the laboratory stressors. Psychophysiological recordings were done during a headache free period. An ANOVA indicated no group effect and no group x …

Soot Formation During Pyrolysis Of Aromatic Hydrocarbons (Modeling, Shock-Tube, Acetylene, Butadiene)., David Warren Clary

LSU Historical Dissertations and Theses

A study combining experimental, empirical modeling, and detailed modeling techniques has been conducted to develop a better understanding of the chemical reactions involved in soot formation during the high-temperature pyrolysis of aromatic and other unsaturated hydrocarbons. The experiments were performed behind reflected shock waves in a conventional shock-tube with soot formation monitored via attenuation of a laser beam at 633nm. Soot-formation measurements were conducted with toluene-argon and benzene-argon mixtures. Detailed kinetic models of soot formation were developed for pyrolyzing acetylene, butadiene, ethylene and benzene. The computational results indicate the importance of compact, fused polycyclic aromatic hydrocarbons as soot intermediates and …

Literature As Phenomenon: Attribution Theory And The Act Of Performance (Oral, Interpretation, Pre-Formance, Newcomb, Bakhtin)., John Walthall Creagh Iii Jan 1985

Literature As Phenomenon: Attribution Theory And The Act Of Performance (Oral, Interpretation, Pre-Formance, Newcomb, Bakhtin)., John Walthall Creagh Iii

LSU Historical Dissertations and Theses

Attribution theory seeks to explain the ways in which humans ascribe causes to everyday events, especially the observed behavior of other human beings. This study seeks to apply the basic patterns of social attribution to the act of "pre-formance"--the aesthetic act in which a performer engages the voice of a literary text and, through rehearsals involving attribuiton, embodies that voice for some audience. Theodore Newcomb's "symmetry theory," a model that contains the essential features of human attribution, is discussed within the philosophical perspective of phenomenology, and the transformed model is used as the basis for a new theory of the …
