Immunocompromise In Gnotobiotic Pigs Induced By Verotoxin-Producing Escherichia Coli (O111:Nm), Jane Christopher-Hennings, Joann A. Willgohs, David H. Francis, Usha A. K. Raman, Rodney A. Moxley, David J. Hurley

School of Veterinary and Biomedical Sciences: Faculty Publications

A verotoxin-producing Escherichia coli serotype O111:NM strain (strain 10049; verotoxin 1 positive) persistently infected experimentally inoculated gnotobiotic pigs, causing attaching-effacing intestinal lesions and chronic diarrhea. Experiments were performed to determine whether persistent infection might be associated with immunocompromise of the host by this organism. Pigs inoculated with this strain had a significant reduction in peripheral blood lymphocytes and lower antibody titers to sheep erythrocytes compared with control pigs. Compared with pigs given a verotoxin-negative pathogenic strain of the same serotype (O111:NM, strain 2430), pigs inoculated with the verotoxin-positive strain had lower peripheral lymphocyte counts and proliferative responses to concanavalin A, …

Lagarocotyle Salamandrae N. Gen., N. Sp. (Monogenoidea, Polyonchoinea, Lagarocotylidae N. Ord.) From The Cloaca Of Rhyacotriton Cascadae Good And Wake (Caudata, Rhyacotritonidae) In Washington State, Delane C. Kritsky, Eric P. Hoberg, K. B. Aubry

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Lagarocotyle salamandrae n. gen., n. sp. (Lagarocotylidea n. ord., Lagarocotylidae n. fam.) is described from the cloaca of the Cascade torrent salamander, Rhyacotriton cascadae Good and Wake (Rhyacotritonidae), from the Lewis River and Wind River drainages of south-central Washington. Lagarocotyle n. gen. is characterized, in part, by a haptor armed with 16 hooks (14 submarginal, two subcentral), blind intestinal ceca, a large testis surrounding the germarium, an open male copulatory organ (not tubular), a dextroventral vaginal pore (at level of copulatory complex), and an egg lacking filaments; eyes, head organs, seminal receptacle, and haptoral anchors and bars are lacking. Lagarocotyle …

Women, Economics, And The Concept Of The Market: A Second Look At Reaganomics, Ann Mari May

College of Business: Faculty Publications

Economic performance during the Reagan years fell far short of the hyperbole surrounding the 1980s. Touted as a period of robust economic expansion, in retrospect, the Reagan years did not produce unusually high growth in total output, resulted in relatively high overall unemployment rates, and ushered in a new era of increased economic instability [May, forthcoming]. During this period of disappointing growth, women and minorities became especially marginalized.

Rapid Assessment Of Drug Susceptibilities Of Mycobacterium Tuberculosis By Means Of Luciferase Reporter Phages, William R. Jacobs Jr., Raul G. Barletta, Rupa Udani, John Chan, Gary Kalkut, Gabriel Sosne, Tobias Kieser, Gary J. Sarkis, Graham F. Hatfull, Barry R. Bloom

School of Veterinary and Biomedical Sciences: Faculty Publications

Effective chemotherapy of tuberculosis requires rapid assessment of drug sensitivity because of the emergence of multidrug-resistant Mycobacterium tuberculosis. Drug susceptibility was assessed by a simple method based on the efficient production of photons by viable mycobacteria infected with specific reporter phages expressing the firefly luciferase gene. Light production was dependent on phage infection, expression of the luciferase gene, and the level of cellular adenosine triphosphate. Signals could be detected within minutes after infection of virulent M. tuberculosis with reporter phages. Culture of conventional strains with antituberculosis drugs, including isoniazid or rifampicin, resulted in extinction of light production. In contrast, …

Evidence For Virus-Encoded Glycosylation Specificity, Ing-Nang Wang, Yu Li, Quideng Que, Meenakshi Bhattacharya, Leslie C. Lane, William G. Chaney, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Four spontaneously derived serologically distinct classes of mutants of the Paramecium bursaria chlorella virus (PBCV-1) were isolated using polydonal antiserum prepared against either intact PBCV-1 or PBCV-1-derived serotypes. The oligosaccharide(s) of the viral major capsid protein and two minor glycoproteins determined virus serological specificity. Normally, viral glycoproteins arise from host-specific glycosylation of viral proteins; the glycan portion can be altered only by growing the virus on another host or by mutations in glycosylation sites of the viral protein. Neither mechanism explains the changes in the glycan(s) of the PBCV-1 major capsid protein because all of the viruses were grown in …

Identifying Bovine Respiratory Syncytial Virus By Reverse Transcription-Polymerase Chain Reaction And Oligonucleotide Hybridizations, R. D. Oberst, M. P. Hays, K. J. Hennessey, L. C. Stine, J. F. Evermann, Clayton L. Kelling

Nebraska Center for Virology: Faculty Publications

An assay to identify tissue culture cells infected with bovine respiratory syncytial virus (BRSV) that utilizes reverse transcription (RT), the polymerase chain reaction (PCR), and a synthetic oligonucleotide hybridization probe has been developed. The RT-PCR assay uses a BRSV-specific negative-sense oligonucleotide primer to synthesize cDNA from a BRSV fusion protein mRNA template and another BRSV-specific oligonucleotide primer (positive sense) upstream from the negative-sense primer for PCR amplification. In the presence of mRNA templates of BRSV isolates originating from locations throughout the United States, the BRSV RT-PCR assay resulted in amplified products (381 bp) that were specific to BRSV, as demonstrated …

Relations Between Social Skills And High-Risk Sexual Interactions Among Adolescents, Douglas W. Nangle, David J. Hansen

Department of Psychology: Faculty Publications

Researchers have begun to employ social-skills training in efforts to change the sexual behavior of adolescents. However, despite the promise of social-skills training, little is known about how social skills are related to the sexual practices of adolescents. The present article reviews the current literature and proposes a conceptual framework for understanding the relations between social skills and sexual behavior of adolescents by (a)examining the relationship between sexual activity and social skills, (b) examining the development of sexual-interaction skills and deficits, (c) summarizing what is currently known about the relations between social skills and sexual behavior, (d) discussing current issues …

A Longitudinal Investigation Of The Relationship Between Educational Investment And Adolescent Sexual Activity, Christine Mccauley Ohannessian, Lisa J. Crockett

Department of Psychology: Faculty Publications

The relation between educational investment and sexual behavior was examined longitudinally in a sample of 479 rural adolescents. Surveys were administered to the subjects twice—once when they were in the 8th, 9th, and 10th grades, and again 2 years later when they were in the 10th, 11th, and 12th grades. Results indicated that among girls, educational investment predicted sexual activity, with academic grades in school significantly predicting reported frequency of sexual activity 2 years later. In contrast for boys, sexual involvement predicted later educational investment, particularly involvement in academic activities. These findings suggest different developmental patterns for boys and girls. …

Pregnancy Rate Is Greater When The Corpus Luteum Is Present During The Period Of Progestin Treatment To Synchronize Time Of Estrus In Cows And Heifers, T. Sanchez, M. E. Wehrman, E. G. M. Bergfeld, K. E. Peters, F. N. Kojima, Andrea S. Cupp, V. Mariscal, Roger J. Kittok, Richard J. Rasby, J. E. Kinder

Department of Animal Science: Faculty Publications

Our hypothesis was that conception in bovine females would be enhanced if the corpus luteum was present during the period of progestin treatment to synchronize estrus. In this study, 67 heifers (one replicate) and 124 cows (two replicates) were randomly assigned to one of two treatment groups. Seven days after estrus (Day 0), all animals were implanted with norgestomet and the implant remained in place for 10 days. All implants were removed on Day 17. Cows and heifers in one group received prostaglandin F_2α (PGF_2α) on Day 7 of the estrous cycle (PG 7; norgestomet without corpus …

Extending Continuous Versus Discontinuous Conditioned Stimuli Before Versus After Unconditioned Stimuli, Melody Albert, Sean Ricker, Rick A. Bevins, John J.B. Ayres

Department of Psychology: Faculty Publications

Conditioned suppression was used with rats to study the effects of extending conditioned stimuli (CSs) before versus after the delivery of unconditioned stimuli. These extensions are termed B and A extensions, respectively. Within-group designs were used to compare the effects of extending CSs when 2-min parts of those CSs were separated by temporal gaps of 6 min versus a separation of no gap. The results were as follows: (a) B extensions weakened conditioning more than did A extensions, with or without gaps; (b) under some conditions, this asymmetrical effect persisted with extended training; (c) gaps between 2-min parts of a …

The Contributions And Challenges Of Family Communication To The Field Of Communication, Sandra Petronio, Dawn O. Braithwaite

Department of Communication Studies: Faculty Publications

As the Family Communication Commission in the Speech Communication Association is off to a good start, it seems appropriate to bring attention to the contributions and challenges studying family communication has for the discipline of communication. More than a decade ago, Bochner (1976) outlined several fruitful areas of investigation. Clearly, people heeded Bochner’s persuasive arguments and produced research on family communication problems (e.g., Bochner & Eisenberg, 1987; Fitzpatrick, 1988; Noller & Fitzpatrick, 1988; Petronio, 1982; Sillars, Weisberg, Burggraff, & Wilson, 1987). But, the need to examine family communication in more depth is essential to the growth and development of the …

Rural Flies In The Urban Environment?, Gustave D. Thomas, Steven R. Skoda

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Because metropolitan areas in the United States have been expanding at a dramatic rate, there has been direct competition between rural and urban interests for land. Also, market pressures often make it most profitable for meat producers to locate as close to urban centers as possible. A resultant growing interface between rural and urban centers, coupled with inadequate understanding of the people between the two centers, provides a potential for problems to develop. This book generally summarizes one area of contention - flies: few people tolerate flies in any setting anymore.
