Microbial Community Structure Dynamics In Ohio River Sediments During Reductive Dechlorination Of Pcbs, Andres Enrique Nunez

University of Kentucky Doctoral Dissertations

The entire stretch of the Ohio River is under fish consumption advisories due to contamination with polychlorinated biphenyls (PCBs). In this study, natural attenuation and biostimulation of PCBs and microbial communities responsible for PCB transformations were investigated in Ohio River sediments.

Natural attenuation of PCBs was negligible in sediments, which was likely attributed to low temperature conditions during most of the year, as well as low amounts of available nitrogen, phosphorus, and organic carbon. Moreover, surface sediments were relatively oxidized, as indicated by the prevalence of aerobic bacteria such as beta- Proteobacteria, alpha-Proteobacteria, Sphingobacteria, and Nitrospira in 16S rRNA sediment …

Federal Government Documents: Dead Or Alive, Charles D. Bernholz

University of Nebraska-Lincoln Libraries: Faculty Publications

Marcel Proust wrote “What we call our future is the shadow that our past projects in front of us.” For the federal documents universe, this is only partially correct. We should attend more to how it has felt to be documents librarians, instead of trying to reconcile the past with all those wishful digital delivery monologues. A lack of courage on our part now—or relying solely upon that handy silhouette—will jeopardize the prospect of tomorrow's federal documents and their use. That absence of daring, or the use of that crutch, will guarantee that whatever results we are handed in our …

Getting Past Conflict Resolution: A Complexity View Of Conflict, Leticia Andrade, Donde Ashmos Plowman, Dennis Duchon

Department of Management: Faculty Publications

The traditional view of conflict, as a problematic condition always requiring reduction or elimination and whose conditions or outcomes can be predicted, is incompatible with a complex adaptive systems view of organizations. Thus, conventional approaches to reducing conflict are often futile because the fundamental properties of complex adaptive systems are the source of much organizational ‘conflict.’ In this paper we offer an alternative view of conflict as pattern fluctuations in complex adaptive systems. Rather than needing reduction or elimination, conflict is the fuel that drives system growth and enables learning and adaptive behaviors, making innovation possible. Instead of focusing on …

Canine Vector-Borne Diseases In Brazil [Review], Filipe Dantas-Torres

Harold W. Manter Laboratory of Parasitology: Library Materials

Canine vector-borne diseases (CVBDs) are highly prevalent in Brazil and represent a challenge to veterinarians and public health workers, since some diseases are of great zoonotic potential. Dogs are affected by many protozoa (e.g. Babesia vogeli, Leishmania infantum, and Trypanosoma cruzi), bacteria (e.g. Anaplasma platys and Ehrlichia canis), and helminths (e.g. Dirofilaria immitis and Dipylidium caninum) that are transmitted by a diverse range of arthropod vectors, including ticks, fleas, lice, triatomines, mosquitoes, tabanids, and phlebotomine sand flies. This article focuses on several aspects (etiology, transmission, distribution, prevalence, risk factors, diagnosis, control, prevention, and public health …

A Synopsis Of Nebraska Grasshopper Distributions, Mathew L. Brust, William Wyatt Hoback, Robert J. Wright

Department of Entomology: Faculty Publications

Between 2005 and 2007, 656 new county records and eight new state records were obtained for Nebraska’s short-horned grasshoppers (Acrididae and Romaleidae). This represents an increase of 30% in the known grasshopper county records in Nebraska. Based on the large number of new distribution records, it appears that the previous distributions of Nebraska’s grasshoppers greatly underestimated the actual distributions. The new grasshopper state records were: Boopedon gracile, Chloealtis abdominalis, Encoptolophus subgracilis, Melanoplus bispinosus, Melanoplus borealis, Melanoplus punctulatus, Paratylotropidia brunneri, and Psinidia fenestralis were obtained. These new records will aid in both grasshopper monitoring for pest outbreaks and in conservation of …

Simulations With Elaborated Worked Example Modeling: Beneficial Effects On Schema Acquisition, Debra K. Meier, Karl J. Reinhard, David O. Carter, David W. Brooks

Department of Entomology: Faculty Publications

Worked examples have been effective in enhancing learning outcomes, especially with novice learners. Most of this research has been conducted in laboratory settings. This study examined the impact of embedding elaborated worked example modeling in a computer simulation practice activity on learning achievement among 39 undergraduate students within a classroom environment. The students from one introductory forensic science course were randomly assigned to one of two groups that worked through computer-based simulations containing worked example modeling conditions presented in varied order. The computer software administered the modeled simulations, prior knowledge test, pretest, posttests, and a second domain test. Findings from …

Influence Of Temperature On Rate Of Uptake And Subsequent Horizontal Transfer Of [14C]Fipronil By Eastern Subterranean Termites (Isoptera: Rhinotermitidae), Neil A. Spomer, Shripat T. Kamble, Richard A. Warriner, Robert W. Davis

Department of Entomology: Faculty Publications

The effect of temperature on [¹⁴C]fipronil uptake and transfer from donor (D) to recipient (R) Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae) workers was evaluated. Test chambers used in the fipronil uptake study were constructed from petri dishes containing autoclaved soil treated with 1 ppm [¹⁴C]fipronil (1.14 μCi of total radioactivity per petri dish), distilled water, and R. flavipes workers. Test chambers were held in environmental growth chambers preset at 12, 17, 22, 27, and 32°C. For the fipronil transfer study, donor termites stained with Nile blue-A were exposed to soil treated with 1 ppm [¹⁴C]fipronil …

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

Objective: The purpose of the present study was to examine the relationship between household food insecurity and maternal depression in a rural sample to determine whether food insecurity predicted mothers’ depression over time or vice versa.

Design: The study employed a prospective design using three waves of data from ‘Rural Families Speak’, a multi-state study of low-income rural families in the USA. Food insecurity was measured using the Core Food Security Module and depression was measured using the Center for Epidemiologic Studies–Depression Scale. A structural equation model was fit to the data using the AMOS software package.

Setting: Sixteen states …

Improved Algorithm For Modis Satellite Retrievals Of Aerosol Optical Depths Over Western North America, Easan Drury, Daniel J. Jacob, Jun Wang, Robert J.D. Spurr, Kelly Chance

Department of Earth and Atmospheric Sciences: Faculty Publications

Quantitative evaluation of chemical transport models (CTMs) with aerosol optical depth (AOD) products retrieved from satellite backscattered reflectances can be compromised by inconsistent assumptions of aerosol optical properties and errors in surface reflectance estimates. We present an improved AOD retrieval algorithm for the MODIS satellite instrument using locally derived surface reflectances and CTM aerosol optical properties for the 0.47, 0.65, and 2.13 μm MODIS channels. Assuming negligible atmospheric reflectance at 2.13 μm in cloud-free conditions, we derive 0.65/2.13 surface reflectance ratios at 1° X 1.25° horizontal resolution for the continental United States in summer 2004 from the subset of top-of-atmosphere …

A 20-Year Plan For Hunter/Angler Recruitment, Development And Retention In Nebraska, Mark Pinkerton, Ron Stave, Mick Jensen, James Ziebarth, Jerrod Burke, Lynn Berggren, George Hall, Kent Forney

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

Hunting and fishing are important parts of Nebraska’s rich heritage. These time-honored outdoor pursuits are important to overall lifestyle, well-being and natural resources of the citizens of Nebraska. The North American Model for Conservation was based primarily on the activism from our nation’s hunters and anglers. Their role helped develop and instill the seven basic premises of the model: Wildlife is to be held in public trust, there should be an elimination of market hunting, wildlife should be allocated by law, there should be hunting/angling opportunities for all citizens, wildlife should only be killed for legitimate reasons, wildlife should be …

Remembering And Forgetting Black Power In Mississippi Burning, Kristen Hoerl

Department of Communication Studies: Faculty Publications

Although critics are correct to point out that Mississippi Burning did not faithfully depict historical events surrounding the real-life disappearances of [civil rights activists] Chaney, Schwerner, and Goodman, I argue that these criticisms overlook some of the ways in which the film advances the cause of racial justice. On a formal level, Mississippi Burning evokes the struggles experienced by members of the Black Power movement, a social movement that emerged on the heels of civil rights. Looking at the film in the context of this movement, I argue that Mississippi Burning is a homology for the Black Power movement. Barry …

Department of Food Science and Technology: Faculty Publications

In this study, the association between genotypic and selected phenotypic characteristics was examined in a collection of Canadian Escherichia coli O157:H7 strains isolated from humans and cattle in the provinces of Alberta, Ontario, Saskatchewan, and Quebec. In a subset of 69 strains selected on the basis of specific phage types (PTs), a strong correlation between the lineage-specific polymorphism assay (LSPA6) genotype and PT was observed with all strains of PTs 4, 14, 21, 31, 33, and 87 belonging to the LSPA6 lineage I (LSPA6-LI) genotype, while those of PTs 23, 45, 67, and 74 belonged to LSPA6 lineage II (LSPA6-LII) …

Contributions Of Children’S Temperament To Teachers’ Judgments Of Social Competence From Kindergarten Through Second Grade, Kathleen Moritz Rudasill, Timothy R. Konold

Department of Educational Psychology: Faculty Publications

Research Findings: Children’s social competence has been linked to successful transition to formal school. The purpose of this study was to examine the contributions of children’s temperament to teachers’ ratings of their social competence from kindergarten through 2nd grade. Children (N = 1,364) from the National Institute of Child Health and Human Development Early Child Care Research Network participated in this study. Mothers rated children’s shyness, attentional focusing, and inhibitory control with the Children’s Behavior Questionnaire at 4½ years, and teachers rated children’s social competence with three subscales (cooperation, assertion, and self-control) of the Social Skills Rating System at …

Addressing Research Gaps In The Intersection Between Homophobia And Bullying, Dorothy L. Espelage, Susan M. Swearer Napolitano

Department of Educational Psychology: Faculty Publications

Bullying, aggression, and peer victimization among adolescents are significant public health concerns. Recent research has demonstrated that bullying and peer victimization sometimes include homophobic epithets directed at heterosexual and lesbian, gay, bisexual, and transgender (LGBT) youth. It appears that being at the receiving end of homophobic banter generally contributes to worse outcomes among youth. This article highlights methodological issues in conducting research with LGBT youth, and stresses the importance of using theoretically and empirically supported definitions, including youth who are sexually questioning, focusing on multiple social and cultural contexts, and examining how support networks serve as buffering agents with regard …

Anabolic Androgenic Steroids: Use And Perceived Use In Non-Athlete College Students, Joseph M. Berning, Kent J. Adams, Mark Debeliso, Bryant A. Stamford, Ian Newman

Department of Educational Psychology: Faculty Publications

Objective: The authors investigated the use and perceived use of anabolic androgenic steroids (AAS) among nonathlete college students. Participants: The authors surveyed a sample of 485 nonathlete college students at a major metropolitan university. Methods: They administered a survey on use and perceived use of AAS to the students. Results: Forty-two participants (9%) reported using AAS (37 men, 5 women). Seniors were the most likely to use AAS (36%), and freshman the least likely (7%). Thirty-four percent of nonusers and 41% of users indicated they knew between 1 and 5 AAS users. Of the total sample, 36% perceived that 5% …

Cell Autonomous Expression Of Inflammatory Genes In Biologically Aged Fibroblasts Associated With Elevated Nf-Kappab Activity., Andres Kriete, Kelli L Mayo, Nirupama Yalamanchili, William Beggs, Patrick Bender, Csaba Kari, Ulrich Rodeck

Department of Dermatology and Cutaneous Biology Faculty Papers

BACKGROUND: Chronic inflammation is a well-known corollary of the aging process and is believed to significantly contribute to morbidity and mortality of many age-associated chronic diseases. However, the mechanisms that cause age-associated inflammatory changes are not well understood. Particularly, the contribution of cell stress responses to age-associated inflammation in 'non-inflammatory' cells remains poorly defined. The present cross-sectional study focused on differences in molecular signatures indicative of inflammatory states associated with biological aging of human fibroblasts from donors aged 22 to 92 years. RESULTS: Gene expression profiling revealed elevated steady-state transcript levels consistent with a chronic inflammatory state in fibroblast cell-strains …

Wolf Body Mass Cline Across Minnesota Related To Taxonomy?, L. David Mech, William J. Paul

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Recent genetic studies suggest that in northern Minnesota two species of wolves (Canis lupus L., 1758 or western wolf and Canis lycaon Schreber, 1775 (= Canis rufus Audubon and Bachman, 1851) or eastern wolf) meet and hybridize. However, little morphological information is available about these two types of wolves in Minnesota. We analyzed the mass of 950 female wolves and 1006 males older than 1 year from across northern Minnesota and found that it increased from 26.30 ± 0.56 kg (mean ± SE) for females and 30.60 ± 0.72 kg for males in northeastern Minnesota to 30.01 ± 0.43 …

Biology And Biological Control Of Exotic True Thistles, Rachel Winston, Rich Hansen, Mark Schwarzlander, Eric Coombs, Carol Bell Randall, Rodney Lym

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

“Thistle” is an old English name for a large variety of weedy, prickly plants that grow throughout the world. The most notable characteristics of thistles are the prickly stems and leaves and the bracts around the flower head. While many different plants have “thistle” in their common name, only certain plant species fit the taxonomic requirements of being considered “true thistles.” True thistle species fall within the family Asteraceae, the tribe Cardueae, and the subtribe Carduinae. Examples of plants that are not true thistles include yellow starthistle (subtribe Centaureinae), sow thistle (subtribe Sonchinae), and Russian thistle (family Chenopodiaceae). Only true …

Evolutionary And Structural Analyses Of Alpha-Papillomavirus Capsid Proteins Yields Novel Insights Into L2 Structure And Interaction With L1, John Lowe, Debasis Panda, Suzanne Rose, Ty Jensen, Willie Hughes, For Yue Tso, Peter C. Angeletti

Nebraska Center for Virology: Faculty Publications

Background: PVs (PV) are small, non-enveloped, double-stranded DNA viruses that have been identified as the primary etiological agent for cervical cancer and their potential for malignant transformation in mucosal tissue has a large impact on public health. The PV family Papillomaviridae is organized into multiple genus based on sequential parsimony, host range, tissue tropism, and histology. We focused this analysis on the late gene products, major (L1) and minor (L2) capsid proteins from the family Papillomaviridae genus Alpha-papillomavirus. Alpha-PVs preferentially infect oral and anogenital mucosa of humans and primates with varied risk of oncogenic transformation. Development of evolutionary associations between …

Early Childhood Infection By Human Herpesvirus 8 In Zambia And The Role Of Human Immunodeficiency Virus Type 1 Coinfection In A Highly Endemic Area, Veenu Minhas, Kay L. Crabtree, Ann Chao, Tendai J. M'Sola, Chipepo Kankasa, Marc Bulterys, Charles D. Mitchell, Charles Wood

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma occurs at high incidence among Zambian adults and children, but there is a paucity of data on human herpesvirus 8 (HHV-8) incidence and routes of infection, especially in children. Between 1998 and 2004, the authors conducted a prospective study of viral transmission in a cohort of 684 children in Lusaka, Zambia, to estimate the annual incidence of HHV-8 from birth through 48 months of age. Maternal and pediatric human immunodeficiency virus type 1 (HIV-1) infection status was also determined. The results, based on 1,532 child-years of follow-up, showed that HHV-8 seroconversion occurs early in life. The incidence rate …

Modified Kigali Combined Staging Predicts Risk Of Mortality In Hiv-Infected Adults In Lusaka, Zambia, Philip J. Peters, Isaac Zulu, Nzali G. Kancheya, Shabir Lakhi, Elwyn Chomba, Cheswa Vwalika, Dhong-Jin Kim, Ilene Brill, Jareen Meinzen-Derr, Amanda Tichacek, Susan A. Allen

Nebraska Center for Virology: Faculty Publications

We assessed the utility of the modified Kigali combined (MKC) staging system for predicting survival in HIV-infected Zambian adults in a prospective, longitudinal, open cohort. From 1995 to 2004, HIV-discordant couples (one HIV-infected partner and one HIV-negative partner) were recruited from couples’ voluntary counseling and testing centers in Lusaka, Zambia and followed at 3-month intervals. MKC stage, which incorporates clinical stage with erythrocyte sedimentation rate (ESR), hematocrit, and body mass index (BMI), was determined at enrollment. Kaplan–Meier survival and Cox proportional hazard methods were used to calculate median survival and relative hazards. We enrolled 1479 HIV-discordant couples with a combined …

Development Of An Immunofluorescence Assay Using Recombinant Proteins Expressed In Insect Cells To Screen And Confirm Presence Of Human Herpesvirus 8-Specific Antibodies, Veenu Minhas, Lynsey N. Crosby, Kay L. Crabtree, Saul Phiri, Tendai J. M'Soka, Chipepo Kankasa, William J. Harrington, Charles D. Mitchell, Charles Wood

Nebraska Center for Virology: Faculty Publications

Human herpesvirus 8 (HHV-8), or Kaposi’s sarcoma (KS)-associated herpesvirus, has been linked to all forms of KS. The results of most current serological assays for the detection of HHV-8-specific antibodies have low levels of concordance among themselves. To establish a sensitive and specific testing strategy that can be used to screen for HHV-8-specific antibodies, three HHV-8 proteins, ORF65, ORF73, and K8.1A, were expressed by using baculoviral vectors in insect cells and incorporated into a monoclonal antibodyenhanced immunofluorescence assay (mIFA) termed the Sf9 three-antigen mIFA. The results obtained by this mIFA were compared to those obtained by a standard mIFA with …

Small-Molecule Cd4 Mimics Interact With A Highly Conserved Pocket On Hiv-1 Gp120, Navid Madani, Arne Schön, Amy M. Princiotto, Judith M. Lalonde, Joel R. Cpurter, Takahiro Soeta, Danny Ng, Liping Wang, Evan T. Brower, Shi-Hua Xiang, Young Do Kwon, Chih-Chin Huang, Richard Wyatt, Peter D. Kwong, Ernesto Freire, Amos B. Smith Iii, Joseph Sodroski

Nebraska Center for Virology: Faculty Publications

Human immunodeficiency virus (HIV-1) interaction with the primary receptor, CD4, induces conformational changes in the viral envelope glycoproteins that allow binding to the CCR5 second receptor and virus entry into the host cell. The small molecule NBD-556 mimics CD4 by binding the gp120 exterior envelope glycoprotein, moderately inhibiting virus entry into CD4-expressing target cells, and enhancing CCR5 binding and virus entry into CCR5-expressing cells lacking CD4. Studies of NBD-556 analogues and gp120 mutants suggest that: 1) NBD-556 binds within the Phe 43 cavity, a highly conserved, functionally important pocket formed as gp120 assumes the CD4- bound conformation; 2) the NBD-556 …

The Human Immunodeficiency Virus Type 1 Envelope Confers Higher Rates Of Replicative Fitness To Perinatally Transmitted Viruses Than To Nontransmitted Viruses, Xiaohong Kong, John T. West, Hong Zhang, Danielle M. Shea, Tendai J. M’Soka, Charles Wood

Nebraska Center for Virology: Faculty Publications

Selection of a minor viral genotype during perinatal transmission of human Immunodeficiency virus type 1

(HIV-1) has been observed, but there is a lack of information on the correlation of the restrictive transmission

with biological properties of the virus, such as replicative fitness. Recombinant viruses expressing the enhanced

green fluorescent protein or the Discosoma sp. red fluorescent (DsRed2) protein carrying the V1 to V5

regions of env from seven mother-infant pairs (MIPs) infected by subtype C HIV-1 were constructed, and

competition assays were carried out to compare the fitness between the transmitted and nontransmitted

viruses. Flow cytometry was used to …

Varying Efficiency Of Long-Term Replication Of Papillomaviruses In Saccharomyces Cerevisiae, Adam J. Rogers, Malte Loggen, Karen Lee, Peter C. Angeletti

Nebraska Center for Virology: Faculty Publications

Human papillomaviruses (HPVs) replicate in mitotically active basal keratinocytes. Two virally encoded proteins, E1, a helicase, and E2, a transcription factor, are important players in replication and maintenance of HPV episomes. We previously showed that HPV16 could replicate stably in Saccharomyces cerevisiae [Angeletti, P.C., Kim, K., Fernandes, F.J., and Lambert, P.F. (2002)] and we identified cis-elements that mediate replication and maintenance [J. Virol. 76(7), 3350-3358.; Kim, K., Angeletti, P.C., Hassebroek, E.C., and Lambert, P.F. (2005)]. Here, we demonstrate that although multiple HPV genomes replicate stably in yeast, they do so with differing long-term efficiency; HPV6-Ura3 is replicated at the …

Effects Of Shielding Adenoviral Vectors With Polyethylene Glycol On Vector-Specific And Vaccine-Mediated Immune Responses, Eric A. Weaver, Michael A. Barry

Nebraska Center for Virology: Faculty Publications

Many individuals have been previously exposed to human adenovirus serotype 5 (Ad5). This prior immunity has long been known to hinder its use for gene therapy and as a gene-based vaccine. Given these immunogenicity problems, we have tested whether polyethylene glycol (PEG) can blunt immune effects against Ad5 during systemic and mucosal vaccination. Ad5 vectors were covalently modified with 5-, 20-, and 35-kDa linear PEG polymers and evaluated for their ability to produce immune responses against transgene antigen prod- ucts and the vector itself. We show that shielding Ad5 with different-sized PEGs generally reduces transduction and primary antibody responses by …

Effects, Uptake, And Fate Of 2,4,6-Trinitrotoluene Aged In Soil In Plants And Worms, Elly Ph Best, Henry E. Tatem, Kaaren N. Geter, Melissa L. Wells, Brian K. Lane

United States Army Corps of Engineers, Omaha District

The present study was aimed at providing data to be used at predicting exposure-based effects of 2,4,6-trinitrotoluene (TNT) aged in soil on endpoint organisms representing two trophic levels. These data can be used to define criteria or reference values for environmental management and conducting specific risk assessment. Long-term exposure tests were conducted to evaluate sublethal toxicity and uptake of aged soil-based explosives, with TNT as the main contaminant. In these tests, plants were exposed for 55 d, and biomass and explosives residues were determined. Worms were exposed for 28 and 42 d, and biomass, number, and tissue residues were determined. …
