Zim1, A Maternally Expressed Mouse Kruppel-Type Zinc-Finger Gene Located In Proximal Chromosome 7, Joomyeong Kim, Xiaochen Lu, Lisa Stubbs Jan 1999

Zim1, A Maternally Expressed Mouse Kruppel-Type Zinc-Finger Gene Located In Proximal Chromosome 7, Joomyeong Kim, Xiaochen Lu, Lisa Stubbs

Faculty Publications

In analysis of a conserved region of proximal mouse chromosome 7 and human chromosome 19q, we have isolated a novel mouse gene, Zim1 (imprinted zinc-finger gene 1), encoding a typical Kruppel-type (C2H2) zinc-finger protein, located within 30 kb of a known imprinted gene, Peg3 (paternally expressed gene 3). Our studies demonstrate that Zim1 is also imprinted; the gene is expressed mainly from the maternal allele and at high levels only during embryonic and neonatal stages. In contrast to most tissues, Zim1 is expressed biallelically in neonatal and adult brain with slightly more input from the maternal allele. Zim1 produces multiple …

Ferric Iron Reduction By Bacteria Associated With The Roots Of Freshwater And Marine Macrophytes, G. M. King, Meredith A. Garey Jan 1999

Ferric Iron Reduction By Bacteria Associated With The Roots Of Freshwater And Marine Macrophytes, G. M. King, Meredith A. Garey

Faculty Publications

In vitro assays of washed, excised roots revealed maximum potential ferric iron reduction rates of >100 μmol g (dry weight)-1 day-1 for three freshwater macrophytes and rates between 15 and 83 μmol (dry weight)-1 day-1 for two marine species. The rates varied with root morphology but not consistently (fine root activity exceeded smooth root activity in some but not all cases). Sodium molybdate added at final concentrations of 0.2 to 20 mM did not inhibit iron reduction by roots of marine macrophytes (Spartina alterniflora and Zostera marina). Roots of a freshwater macrophyte, Sparganium eurycarpum, that were incubated with an analog …

Complementation Of Conjugation Functions Of Streptomyces Lividans Plasmid Pij101 By The Related Streptomyces Plasmid Psb24.2, Gregg S. Pettis, Shubha Prakash Jan 1999

Complementation Of Conjugation Functions Of Streptomyces Lividans Plasmid Pij101 By The Related Streptomyces Plasmid Psb24.2, Gregg S. Pettis, Shubha Prakash

Faculty Publications

A database search revealed extensive sequence similarity between Streptomyces lividans plasmid pIJ101 and Streptomyces plasmid pSB24.2, which is a deletion derivative of Streptomyces cyanogenus plasmid pSB24.1. The high degree of relatedness between the two plasmids allowed the construction of a genetic map of pSB24.2, consisting of putative transfer and replication loci. Two pSB24.2 loci, namely, the cis-acting locus for transfer (clt) and the transfer-associated korB gene, were shown to be capable of complementing the pIJ101 clt and korB functions, respectively, a result that is consistent with the notion that pIJ101 and the parental plasmid pSB24.1 encode highly similar, if not …

Rapid Evolution Of Fertilization Selectivity And Lysin Cdna Sequences In Teguline Gastropods, Michael E. Hellberg, Victor D. Vacquier Jan 1999

Rapid Evolution Of Fertilization Selectivity And Lysin Cdna Sequences In Teguline Gastropods, Michael E. Hellberg, Victor D. Vacquier

Faculty Publications

Proteins mediating intercellular recognition face opposing selective forces as they evolve: purifying selection to maintain function, and diversifying selection to alter specificity. Lysin is a 16-kDa protein which enables sperm of free-spawning marine snails to make a hole in the vitelline layer (VE) surrounding conspecific eggs. Previous work on abalone (Haliotis spp.) has shown that positive selection promotes rapid interspecific divergence of lysin. Here, we present data on the specificity of VE dissolution by four species of teguline gastropods, along with lysin cDNA sequences. The teguline and abalone lineages diverged over 250 MYA. As in abalone, VE dissolution by lysin …

Inhibition Of Plant-Pathogenic Fungi By A Corn Trypsin Inhibitor Overexpressed In Escherichia Coli, Zhi Yuan Chen, Robert L. Brown, Alan R. Lax, Thomas E. Cleveland, John S. Russin

Faculty Publications

The cDNA of a 14-kDa trypsin inhibitor (TI) from corn was subcloned into an Escherichia coli overexpression vector. The overexpressed TI was purified based on its insolubility in urea and then refolded into the active form in vitro. This recombinant TI inhibited both conidium germination and hyphal growth of all nine plant pathogenic fungi studied, including Aspergillus flavus, Aspergillus parasiticus, and Fusarium moniliforme. The calculated 50% inhibitory concentration of TI for conidium germination ranged from 70 to more than 300 μg/ml, and that for fungal growth ranged from 33 to 124 μg/ml depending on the fungal species. It also inhibited …

Maximum-Likelihood Generalized Heritability Estimate For Blood Pressure In Nigerian Families, Charles N. Rotimi, Richard S. Cooper, Guichan Cao, Olufemi Ogunbiyi, Modupe Ladipo, Eme Owoaje, Ryk Ward

Faculty Publications

Elevated blood pressure (BP) is more common in relatives of hypertensives than in relatives of normotensives, indicating familial resemblance of the BP phenotypes. Most published studies have been conducted in westernized societies. To assess the ability to generalize these estimates, we examined familial patterns of BP in a population-based sample of 510 nuclear families, including 1552 individuals (320 fathers, 370 mothers, 475 sons, and 387 daughters) from Ibadan, Nigeria. The prevalence of obesity in this community is low (body mass index: fathers 21.6; mothers, 23.6; sons, 19.2; and daughters=21.0 kg/m2). The BP phenotype used in all analyses was created from …

Self-Reported Health Status And Mortality In A Multiethnic Us Cohort, Daniel L. Mcgee, Youlian Liao, Guichan Cao, Richard S. Cooper Jan 1999

Self-Reported Health Status And Mortality In A Multiethnic Us Cohort, Daniel L. Mcgee, Youlian Liao, Guichan Cao, Richard S. Cooper

Faculty Publications

The authors examined the relation between self-reported health status and mortality among the following racial/ethnic groups: Native Americans, Asian/Pacific Islanders, blacks, whites, and Hispanics. They pooled 1986- 1994 data from the National Health Interview Survey to obtain information on more than 700,000 cohort participants. Although fewer than 5,000 Native Americans are included in this cohort, the data provide information previously unavailable for this group. Also included are almost 17,000 Asian/Pacific Islanders, over 90,000 blacks, and over 50,000 Hispanics. The authors found strong associations between self-reported health status and both socioeconomic status and subsequent mortality. A self-report of fair or poor …

Faculty Publications

By virtue of its potential effects on rates of energy expenditure, uncoupling protein 3 (UCP3) is an obesity candidate gene. We identified nine sequence variants in UCP3, including Va19Met, Val102Ile, Arg282Cys, and a splice site mutation in the intron between exons 6 and 7. The splice mutation results in an inability to synthesize mRNA for the long isoform (UCP3L) of UCP3. Linkage (sib pair), association, and transmission disequilibrium testing studies on 942 African-Americans did not suggest a significant effect of UCP3 on body composition in this group. In vastus lateralis skeletal muscle of individuals homozygous for the splice mutation, no …

Statistical Prediction Based On Censored Life Data, Luis A. Escobar, William Q. Meeker Jan 1999

Statistical Prediction Based On Censored Life Data, Luis A. Escobar, William Q. Meeker

Faculty Publications

This article describes methods for using censored life data to construct prediction bounds or intervals for future outcomes. Both new-sample prediction (e.g., using data from a previous sample to make predictions on the future failure time of a new unit) and within-sample prediction problems (e.g., predicting the number of future failures from a sample, based on early data from that sample) are considered. The general method, based on an assumed parametric distribution, uses simulationbased calibration. This method provides exactly the nominal coverage probability when an exact pivotal-based method exists and a highly accurate large-sample approximation, otherwise. To illustrate new-sample prediction, …

Effects Of Heat-Sensitive Agents, Soil Type, Moisture, And Leaf Surface On Persistence Of Anticarsia Gemmatalis (Lepidoptera: Noctuidae) Nucleopolyhedrovirus, F. Peng, J. R. Fuxa, A. R. Richter, S. J. Johnson

Faculty Publications

In a laboratory experiment, persistence of Anticarsia gemmatalis Hubner nucleopolyhedrovirus (AgNPV) was significantly lower in marsh soil than in agricultural soil. AgNPV was inactivated significantly more quickly in soil at -0.3 bar water potential than in soil at water potentials of 0 bar or -5 bar. Loss of AgNPV activity was significantly faster in unautoclaved soil than in autoclaved soil. AgNPV stored in unautoclaved marsh water lost 99% of its activity within 64 d, whereas AgNPV in distilled water or autoclaved marsh water remained 98-99% active after the same time period. The soil and marsh-water results indicate that 1 or …

Toxicity Of Selected Insecticides To Fall Armyworms (Lepidoptera: Noctuidae) In Laboratory Bioassay Studies, J. J. Adamczyk, B. R. Leonard, J. B. Graves

Faculty Publications

Efficacy of conventional and experimental insecticides against the fall armyworm, Spodoptera frugiperda (J. E. Smith), was evaluated in laboratory bioassays. In a laboratory diet bioassay, third instars of a laboratory-strain were more susceptible to novel insecticides, including chlorfenapyr, methoxyfenozide, spinosad, and tebufenozide, than to a recommended insecticide, thiodicarb. In other laboratory bioassays, fall armyworms were fed field grown cotton leaves, white flowers, or bolls treated with one of two recommended insecticides, L-cyhalothrin or thiodicarb, or one of four experimental insecticides, chlorfenapyr, emamectin benzoate, methoxyfenozide, or spinosad. First instar mortality was significantly greater on leaves treated with chlorfenapyr, L-cyhalothrin, or thiodicarb …

Susceptibility Of Different Instars Of European Corn Borer (Lepidoptera: Crambidae) To Diet Containing Bacillus Thuringiensis, Fangneng Huang, Lawrent L. Buschman, Randall A. Higgins

Faculty Publications

The relative susceptibility of different instars of the European corn borer, Ostrinia nubilalis (Hubner), to a commercial formulation of Bacillus thuringiensis Berliner subsp. kurstaki, Dipel ES, was determined using diet incorporation. European corn borers exposed to Dipel during the 1st instar were much more susceptible than were older larvae. No significant differences in susceptibility were found among 3rd, 4th, and 5th instars at doses of 0.03-0.81 ml of Dipel per kilogram of diet. At high concentrations (2.43 ml/km of diet), 5th instars had significantly lower mortality than did 3rd or 4th instars. The LC50 and LC90 of the 5th instars …

Bromoxynil And Pyrithiobac Weed Control Systems In Transgenic Bxn Cotton., Christopher Brett Corkern

LSU Historical Dissertations and Theses

Field studies conducted in 1996 through 1998 evaluated grass control with the graminicides clethodim, fluazifop-P, quizalofop-P, and sethoxydim alone and in combination with bromoxynil. Sequential application of bromoxynil at 1.7 kg ai/ha 7, 3, and 1 day (d) before or 1, 3, and 7 d after each graminicide reduced antagonism of rhizome johnsongrass [Sorghum halepense (L.) Pers.] control when compared with bromoxynil plus clethodim, fluazifop-P, or quizalofop-P. Antagonism of johnsongrass control associated with bromoxynil and graminicide mixtures reduced cotton yield 17%. A 3 d or greater interval between bromoxynil and graminicide application was necessary to maximize cotton yield. Bromoxynil at …

Numerical Simulation And Experimental Verification Of Cone Penetration Rate And Anisotropy In Cohesive Soils., Daekyu Kim

LSU Historical Dissertations and Theses

This research focuses on the effects of cone penetration rate and anisotropy on the results of piezocone penetration and subsequent dissipation tests. Finite element analyses, and miniature piezocone penetration and dissipation tests in a calibration chamber were performed, then the results were compared. The anisotropic elastoplastic-viscoplastic; bounding surface model was chosen as a soil model and it was implemented into a computer program, ANCALBR8. The isotropic/anisotropic triaxial compression, creep tests, and oedometer tests were performed to determine the model parameter values and verify the model. The model showed very good agreement with the triaxial test results. The theoretical formulation was …

Thickness Of Knots, R. A. Litherland, J. Simon, O. Durumeric, E. Rawdon Jan 1999

Thickness Of Knots, R. A. Litherland, J. Simon, O. Durumeric, E. Rawdon

Faculty Publications

Classical knot theory studies one-dimensional filaments; in this paper we model knots as more physically "real", e.g., made of some "rope" with nonzero thickness. A motivating question is: How much length of unit radius rope is needed to tie a nontrivial knot? For a smooth knot K, the "injectivity radius" R(K) is the supremum of radii of embedded tubular neighborhoods. The "thickness" of K, a new measure of knot complexity, is the ratio of R(K) to arc-length. We relate thickness to curvature, self-distance, distortion, and (for knot types) edge-number. © 1999 Elsevier Science B.V. All rights reserved.

Image Segmentation With A Finite Element Method, Blaise Bourdin Jan 1999

Image Segmentation With A Finite Element Method, Blaise Bourdin

Faculty Publications

The Mumford-Shah functional for image segmentation is an original approach of the image segmentation problem, based on a minimal energy criterion. Its minimization can be seen as a free discontinuity problem and is based on Γ-convergence and bounded variation functions theories. Some new regularization results, make possible to imagine a finite element resolution method. In a first time, the Mumford-Shah functional is introduced and some existing results are quoted. Then, a discrete formulation for the Mumford-Shah problem is proposed and its Γ-convergence is proved. Finally, some numerical results, computed from both artificial and real images are presented and discussed.
