Insertional Inactivation Of Treponema Denticola Tap1 Results In A Nonmotile Mutant With Elongated Flagellar Hooks, Ronald J. Limberger, Linda L. Slivienski, Jacques Izard, William A. Samsonoff

Department of Food Science and Technology: Faculty Publications

The treponemal fla operon is comprised of numerous motility-related genes; however, the initial gene of this operon, tap1, has no known function. A recently developed system to generate specific mutants in Treponema denticola was utilized to determine if Tap1 was essential for motility. T. denticola tap1 and flanking DNA were identified, cloned, and sequenced, and a suicide plasmid that contained tap1 interrupted with an erythromycin resistance cassette (ermF and ermAM) was constructed. Because of potential polar effects from this cassette, a second plasmid that contained tap1 interrupted with a modified erythromycin resistance cassette that lacked the putative ermF transcription …

Regime Type, Strategic Interaction, And The Diversionary Use Of Force, Ross A. Miller

Department of Political Science: Faculty Publications

This study explores the relative propensity of democratic and autocratic regimes to engage in diversionary behavior. Although previous research has focused on the willingness of leaders to engage in conflict, recent studies suggest an alternative explanation: the effect of strategic interaction opportunities. Previous studies suggest that even though democratic leaders may have an incentive to use foreign policy to manipulate domestic audiences, would-be adversaries limit their interaction opportunities. This article extends the analysis to a comparison of the behavior of democratic and autocratic regimes. Using three different indicators of the domestic political vulnerability of leaders—economic growth rates, protests, and rebellions—the …

Turning Points In The Development Of Blended Families, Leslie A. Baxter, Dawn O. Braithwaite, John H. Nicholson

Department of Communication Studies: Faculty Publications

A modified retrospective interview technique (RIT) was employed with members of 53 blended families to determine the types of turning points they reported experiencing and the developmental trajectories of their respective blended family’s first 4 years. Findings revealed 15 primary types of turning points, of which “Changes in Household Configuration,” “Conflict,” “Holidays/Special Events,” “Quality Time,” and “Family Crisis” were the most frequent. A cluster analysis revealed five basic trajectories of development for the first 48 months of family development: Accelerated, Prolonged, Stagnating, Declining, and High-Amplitude Turbulent. The trajectories differed in the overall positive-to-negative valence ratio, the frequency of conflict related …

An Engineered Closterovirus Rna Replicon And Analysis Of Heterologous Terminal Sequences For Replication, Satyanarayana Tatineni, Siddarame Gowda, V. P. Boyko, Maria R. Albiach-Marti, Munir Mawassi, J. Navas-Castillo, Alexander V. Karasev, V. Dolja, Mark E. Hilf, D. J. Lewandowski, P. Moreno, Moshe Bar-Joseph, S. M. Garnsey, William O. Dawson

Department of Plant Pathology: Faculty Publications

Citrus tristeza virus (CTV) populations in citrus trees are unusually complex mixtures of viral genotypes and defective RNAs developed during the long-term vegetative propagation of the virus and by additional mixing by aphid transmission. The viral replication process allows the maintenance of minor amounts of disparate genotypes and defective RNAs in these populations. CTV is a member of the Closteroviridae possessing a positive-stranded RNA genome of ≈20 kilobases that expresses the replicase-associated genes as an ≈400-kDa polyprotein and the remaining 10 3' genes through subgenomic mRNAs. A full-length cDNA clone of CTV was generated from which RNA transcripts capable of …

Biodegradation Of Thermoplastic And Hermosetting Polyesters From Z-Protected Glutamic Acid, R M. Tadros, Hossein Noureddini, Delmar C. Timm

Papers in Biomolecular Engineering

In a previous article,1 the development and molecular characterization of three polyesters from N-carbobenzyloxy-L-glutamic acid (ZGluOH) were reported. The polymers were a linear, heterochain polyester (ZGluOH and ethylene glycol), a crosslinked heterochain polyester (ZGluOH and diglycidyl ether of 1,4-butanediol), and a crosslinked, heterochain aromatic polyester (ZGluOH and diglycidyl ether of bisphenol A). In this manuscript, results of biodegradation studies are reported. The three polymers hydrolyzed to low molecular weight oligomers similar to the monomers with lipase. When exposed to a mixed culture of micro-organisms, the first two resins degraded to biomass and respiratory gases. The crosslinked heterochain aromatic polyester resisted …

Quality Assurance And The Scientific Method, Ray T. Sterner

United States Department of Agriculture Wildlife Services: Staff Publications

As all RMRCSQA members know, during the 1980s the Environmental Protection Agency (EPA) and the Food a d Drug Administration (FDA) implemented 40 Code of Federal Regulations (CFR) Parts 160/792 and 21 CFR Part 58, respectively. These regulations outlined GLPs for data data collections needed to register pesticides, toxic substances, and drugs in the U.S.; QA concepts fix study oversight Were also described in these parts (see Sterner and Fagerstone, 1997). What you may not have considered is the relationship of these regulations to the scientific method.

Molybdenum Accumulation In Cariaco Basin Sediment Over The Past 24 K.Y.: A Record Of Water-Column Anoxia And Climate, Walter E. Dean, David Z. Piper, Larry C. Peterson

United States Geological Survey: Staff Publications

Molybdenum (Mo) concentrations in a sediment core from the Cariaco basin on the Venezuelan continental shelf can be partitioned between a marine fraction and a terrigenous fraction. The accumulation rate of the marine fraction of Mo increased abruptly 15 000 calendar years ago (15 ka), from <0.5 mg • cm^-2 • yr^-1 to >4 μg • cm^-2 • yr^-1, and then decreased abruptly at 9 ka. The accumulation rate remained high throughout this 6 k.y. period, but exhibited maxima at 15–14 and 12.5 ka, corresponding in time to meltwater pulse IA into the Gulf of Mexico and the onset …

Scyphophyllidium Uruguayense N. Sp. (Eucestoda: Tetraphyllidea) In Mustelus Mento (Cope, 1877) (Chondrichthyes: Carcharhiniformes: Triakidae) From La Paloma, Uruguay, Daniel R. Brooks, Fernando Marques, Carla Perroni, Corina Sidagis

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of Scyphophyllidium inhabits Mustelus mento near La Paloma, Uruguay. It resembles Scyphophyllidium giganteum from the Atlantic Ocean and specimens identified as S. giganteum from California by having anapolytic strobilae 155-258 mm long, 250-300 craspedote proglottids, scoleces 1.2-1.4 mm wide, necks 34-41 mm long, immature and mature proglottids wider than long, gravid proglottids wider than long to longer than wide, genital pores averaging 28% of proglottid length from the anterior end, relatively flat ovaries with digitiform lobes reaching the lateralmost extent of the testicular field, vitellaria in 2 fields converging toward the proglottid midline, straight and short cirrus …

Pararhinebothroides Hobergi N. Gen. N. Sp. (Eucestoda: Tetraphyllidea) In Urobatis Tumbesensis (Chondrichthyes: Myliobatiformes) From Coastal Ecuador, David Zamparo, Daniel R. Brooks, Ramiro Barriga

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of tetraphyllidean eucestode inhabiting Urobatis tumbesensis from inshore waters of southeastern Ecuador shares 3 synapomorphies with Rhinebothroides spp.: apical bothridial suckers poorly differentiated from the marginal loculi, internal seminal vesicles, and insertion of the vas deferens dorsally closer to the poral than the aporal end of the cirrus sac. The new species differs from Rhinebothroides spp. by lacking medial bothridial septa and loculi and having symmetrical ovarian arms, and possesses an apparent autapomorphic trait by having the vas deferens tapering to a narrow tube before entering the cirrus sac, extending posteriorly to the posterior end of the …

Macroevolutionary Patterns Of Male Reproductive Investment In A Clade Of Parasitic Hermaphrodites, David Zamparo, Deborah A. Mclennan, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The Eucestoda is particularly relevant for questions concerning reproductive investment in male gametes because no other parasitic group displays such diversity in testis size and number within and among species. This diversity has long been used as a valuable taxonomic character, but few researchers have ever investigated its evolutionary significance. In this paper we investigate the evolution of testis number and size within Rhinebothroides (Platyhelminthes: Eucestoda). Our comparative, phylogenetic analysis revealed that overall allocation to male functions, as measured by relative testicular area, does not change within the clade, even though the packaging of that investment in numerous testes is …

Species: Turning A Conundrum Into A Research Program, Daniel R. Brooks, Deborah A. Mclennan, E. C. Bernard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The most appropriate ontological basis for understanding the role of species in evolutionary biology is the Evolutionary Species Concept. The ESC is not an operational concept, but one version of the Phylogenetic Species Concept is. Linking the ontology of species with the epistemological basis of actual biological studies requires that we specify both a discovery mode for identifying collections of organisms that we believe are evolutionary species, and a series of evaluation criteria for assessing those entities we have discovered. Simply naming a collection of specimens, no matter how strong one’s evolutionary beliefs, is not sufficient for declaring that evolutionary …

Histogenesis In The Metacestode Of Echinococcus Vogeli And Mechanism Of Pathogenesis In Polycystic Hydatid Disease, Robert L. Rausch, Antonio D'Alessandro

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Histogenesis of the metacestode of Echinococcus vogeli was traced mainly in rodents inoculated intraperitoneally with finely minced infective vesicles. The fragments aggregated in the peritoneal cavity and coalesced, forming structures (plaques) from which primary vesicles arose. From primordia in their germinal tissue, exogenous vesicles developed, enlarged, and migrated outward to the surface of the laminated membrane, where they remained attached and proliferated. Each unit of vesicles so formed retained discrete identity and, within 6-8 months, acquired an adventitia; thereafter, exogenous multiplication ceased and endogenous proliferation supervened. Large numbers of daughter cysts arose in the germinal tissue lining chambers within the …

Room To Maneuver: !Kung Women Cope With Men, Patricia Draper

Department of Anthropology: Faculty Publications

Among the !Kung San of Botswana, women are sometimes beaten by their husbands and coerced by other men, particularly their fathers. The factors that contribute to this form of aggression are various and are changing over time as a consequence of new economic and residential practices now seen among the !Kung as they have transformed themselves from mobile foragers to primarily sedentary food producers. The responses of women and their supporters to incidents of wife abuse are also changing. In this essay several episodes of wife beating that came to my attention during recent fieldwork among the !Kung will be …

Novel Application Of Phastsystem Polyacrylamide Gel Electrophoresis Using Restriction Fragment Length Polymorphism ± Internal Transcribed Spacer Patterns Of Individuals For Molecular Identification Of Entomopathogenic Nematodes, Horolma Pamjav, Dimitra Triga, Zsuzsanna Buzµs, Tibor Vellai, Attila Lucskai, Byron Adams, Alexander P. Reid, Ann Burnell, Christine Griffin, Itamar Glazer, Michael G. Klein, Andras Fodor

Department of Plant Pathology: Faculty Publications

A relatively rapid and economic way of identifying and assigning nematodes to taxons, which had already been determined either by comparative sequence analysis of nuclear rDNA internal transcribed spacer (ITS) region or by other methods of molecular or conventional taxonomy, is provided. Molecular identification of entomopathogenic nematodes (EPN) can be upgraded by basing it on PhastSystem polyacrylamide gel electrophoresis (PAGE) analysis of restriction fragment length polymorphism (RFLP) patterns of polymerase chain reaction (PCR)-amplified DNA derived from single nematodes of Steinernema or Heterorhabditis spp. Although analysis from single worms has previously been made on agarose gel, the resolution on PhastSystem PAGE …

Field And Laboratory Evaluation Of Soil Quality Changes Resulting From Injection Of Liquid Sewage Sludge, S. Stamatiadis, John W. Doran, Timothy A. Kettler

Department of Agronomy and Horticulture: Faculty Publications

Soil quality changes resulting from repeated or single injection of liquid municipal sewage sludge were evaluated in terraced cropland in eastern Nebraska, USA. Differences in soil properties among sampling locations were explained primarily by two factors, landscape position and sludge injection. Selected chemical properties (pH, EC, NO ₃-N) did not generally differ between landscape positions, but soil organic matter (organic C and N) and microbial activity indices (soil respiration, biomass N, available N, mineralization and nitrification rates) were more sensitive indicators of change. Values of these indicators generally increased down-slope from the upper terrace to the grassed waterway on …

Ecological Intensification Of Cereal Production Systems: Yield Potential, Soil Quality, And Precision Agriculture, Kenneth G. Cassman

Department of Agronomy and Horticulture: Faculty Publications

Wheat (Triticum aestivum L.), rice (Oryza sativa L.), and maize (Zea mays L.) provide about two-thirds of all energy in human diets, and four major cropping systems in which these cereals are grown represent the foundation of human food supply. Yield per unit time and land has increased markedly during the past 30 years in these systems, a result of intensified crop management involving improved germplasm, greater inputs of fertilizer, production of two or more crops per year on the same piece of land, and irrigation. Meeting future food demand while minimizing expansion of cultivated area primarily …

Genetic Variation In Geographical Populations Of Western And Mexican Corn Rootworm, A. L. Szalanski, R. L. Roehrdanz, D. B. Taylor, L. Chandler

Department of Plant Pathology: Faculty Publications

Genetic variation in the nuclear rDNA ITS1 region of western corn rootworm, Diabrotica virgifera virgifera (WCR), and Mexican corn rootworm, D. v. zeae (MCR) was studied. Two sites were detected which differentiated WCR and MCR in the 642-base sequence. Polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) analysis of the first internal transcribed spacer region (ITS1) sequence revealed no variation within or among the twelve WCR and two MCR populations. PCR-RFLP of 75% of the mitochondrial DNA genome detected one significant polymorphic site out of the approximately 190 restriction sizes observed in WCR. The polymorphism did not differentiate geographical populations of …

Data-Based Clinical Decision Making In The Treatment Of An Adolescent With Severe Conduct Problems, Douglass W. Nangle, Rebecca E. Carr, David J. Hansen

Department of Psychology: Faculty Publications

This case illustrates the contributions of continuous data monitoring to clinical decision making in the treatment of an adolescent with severe conduct problems. Treatment began with a comprehensive point system that required the continual monitoring of a range of target behaviors. Beginning each session with a review of graphs of the monitored behaviors helped keep the sessions focused and rewarded the client and his parents with visual feedback of their progress. A subjective rating system was also implemented in which the client’s parents quantified their evaluations of his overall behavior on a daily basis. This system enhanced the client’s parents’ …

Early Adolescence And Prosocial/Moral Behavior Ii: The Role Of Social And Contextual Influences, Gustavo Carlo, Richard A. Fabes, Deborah Laible, Kristina Kupanoff

Department of Psychology: Faculty Publications

This is the second installment of the special issue on prosocial and moral development in early adolescence. This issue focuses on social and contextual processes in young adolescents’ prosocial and moral behaviors. In this introductory article, a brief review of the research on parents or family, peers, school environment, culture, and nationality as correlates of prosocial and moral development was presented. The research indicates that the social context plays an important role in prosocial and moral development. However, research on the social and contextual correlates of prosocial and moral development in early adolescence is at an embryonic stage. Research is …

Expression And Action Of Transforming Growth Factor Beta (Tgfβ1, Tgfβ2, And Tgfβ3) During Embryonic Rat Testis Development, Andrea S. Cupp, Grace Kim, Michael K. Skinner

Department of Animal Science: Faculty Publications

The objective of the current study was to determine the role of transforming growth factor beta (TGFβ) during seminiferous cord formation and embryonic testis development. The expression pattern of mRNA for TGFβ isoforms was evaluated during testis development through a quantitative reverse transcription polymerase chain reaction (QRT-PCR) procedure. Expression of mRNA for TGFβ1 was highest at postnatal day 0 (P0) and P10. In contrast, TGFβ2 was high at embryonic day 15 (E15), declined at E16, and showed a transient increase at P0 through P3 of testis development. Interestingly, expression of mRNA for TGFβ3 was high during embryonic development and then …
