The Phenomenon Of Amoralism: An Investigation Of The Cognitive And Emotive Roots, Andrei G. Zavaliy

Dissertations, Theses, and Capstone Projects

An amoralist is defined as a person who rejects the claims of moral reasons to special authority, and systematically acts without regard to the generally accepted moral standards. A psychopath can be seen as a paradigm case of an extreme amoralist, although the less severe cases of selective amoralists are considered. The research into the typical behavioral pattern, motivational structure, and the value system of psychopaths can shed light on at least three aspects related to the analysis of the moral agency. First, it can help elucidating the emotive and cognitive conditions necessary for moral performance. Secondly, it can provide …

Development Of Lexical Tone Production In Disyllabic Words By 2- To 6-Year-Old Mandarin-Speaking Children, Puisan Wong

Dissertations, Theses, and Capstone Projects

This study investigated children's development in the production of Mandarin lexical tones in familiar disyllabic words and tested the hypothesis that disyllabic tone contours with more complex fundamental frequency contours are more difficult for children to produce. Participants were forty-four 2- to 6-year-old monolingual Mandarin-speaking children and 12 mothers. Their disyllabic tone productions were elicited by picture naming and low-pass filtered to eliminate lexical information while retaining the fundamental frequency contours. Three Mandarin-speaking judges listened to the filtered stimuli, and categorized the children's and adult's disyllabic tones. Acoustic analysis was performed on selected accurate child and adult productions and on …

Markers Of Dyslexia In Adult Spanish-Speakers Who Report Severe Difficulty Learning English, Elizabeth Ijalba

Dissertations, Theses, and Capstone Projects

The relationship between native-language reading ability and second-language (L2) learning was explored in a cohort of 60 adult Spanish-speakers learning English as a second language. The research questions centered on whether underlying nativelanguage deficits associated with dyslexia would be present in a subset of English Language Learners who reported severe difficulty learning English. Our participants were divided into two education groups (below and above12th grade). These two groups were classified into three groups based on self- and teacher- ratings of ease or difficulty in English learning ability: for the high-education group, Poor English Language Learners (PELL, N=7); Good English Language …

Role Of The Reactive Oxygen Species Peroxynitrite In Traumatic Brain Injury, Ying Deng

University of Kentucky Doctoral Dissertations

Reactive oxygen species (ROS) is cytotoxic to the cell and is known to contribute to secondary cell death following primary traumatic brain injury (TBI). We described in our study that PN is the main mediator for both lipid peroxidation and protein nitration, and occurred almost immediately after injury. As a downstream factor to oxidative damage, the peak of Ca2+-dependent, calpainmediated cytoskeletal proteolysis preceded that of neurodegeneration, suggesting that calpain-mediated proteolysis is the common pathway leading to neuronal cell death. The time course study clearly elucidated the interrelationship of these cellular changes following TBI, provided window of opportunity for pharmacological intervention. …

A Comparison Of Oral Motor And Production Training For Children With Speech Sound Disorders, Karen Forrest, Jenya Iuzzini-Seigel

Speech Pathology and Audiology Faculty Research and Publications

Despite the many debates about the usefulness of nonspeech oral motor exercises (NSOMEs) in the treatment of speech disorders, few controlled experiments have evaluated their efficacy in the remediation of phonological/articulatory disorders (PADs). More importantly, the relative effect of NSOMEs compared with traditional production treatment (PT) has not been established. The current study employed an alternating treatment design to evaluate changes in production of sounds targeted by NSOMEs and PT in nine children with PAD. Each subject received treatment on two linguistically distinct sounds in which one sound was treated with NSOMEs and the second sound was targeted with PT. …

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 …

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 …

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. …

Self-Harm, Substance Abuse And Age: Relatedness To Sexually Abusive Behaviors Toward Others By Juveniles, Tara K. Cossel

Department of Psychology: Presentations

The present study analyzes three factors as they relate to functioning: selfharm, substance abuse and age. Research has shown girls highest in mid-adolescent selfharm are those who engage in high levels of bullying (Barker, Arseneault, Brendgen, Fontaine, & Maughan, 2008). Little research has been done to analyze specific behaviors toward others among adolescents who self-harm. Dembo, la Voie, Schmeidler, & Washburn (1987) found a positive correlation between antisocial orientation and illicit drug use. Further research was done to understand the nature of behaviors and functioning of juveniles who abuse substances. Johnson (1988) found a history of substance abuse in the …

Bovine Herpesvirus Type 1 Induces Cell Death By A Cell Type Dependent Fashion, Vicki Geiser, Suzanne Rose, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

Bovine herpesvirus 1 (BHV-1), a member of the alpha-herpesvirinae subfamily, causes significant losses to the cattle industry. BHV-1 establishes latency in trigeminal ganglionic sensory neurons, but periodically reactivates from latency. Previous studies suggested that infection with BHV-1 induced novel morphological changes in rabbit skin cells (RS) versus bovine kidney cells (MDBK). Consequently, we hypothesized that viral infection led to a novel form of cell death in RS cells compared to MDBK cells. To test this hypothesis, we examined the levels of apoptosis in these cell types following infection with BHV-1. Infection of RS, but not MDBK, cells leads to high …

A Review Of The Biology Of Bovine Herpesvirus Type 1 (Bhv-I), Its Role As A Cofactor In The Bovine Respiratory Disease Complex And Development Of Improved Vaccines, Clinton J. Jones, Shafiqul Chowdhury

School of Veterinary and Biomedical Sciences: Faculty Publications

Infection of cattle by bovine herpesvirus type 1 (BHV-1) can lead to upper respiratory tract disorders, conjunctivitis, genital disorders and immune suppression. BHV-1-induced immune suppression initiates bovine respiratory disease complex (BRDC), which costs the US cattle industry approximately 3 billion dollars annually. BHV-1 encodes at least three proteins that can inhibit specific arms of the immune system: (i) bICPO inhibits interferon-dependent transcription, (ii) the UL41.5 protein inhibits CD8⁺ T-cell recognition of infected cells by preventing trafficking of viral peptides to the surface of the cells and (iii) glycoprotein G is a chemokine-binding protein that prevents homing of lymphocytes to …

How Does Age Affect Baseline Screening Mammography Performance Measures? A Decision Model, James Keen, John D. Keen

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: In order to promote consumer-oriented informed medical decision-making regarding screening mammography, we created a decision model to predict the age dependence of the cancer detection rate, the recall rate and the secondary performance measures (positive predictive values, total intervention rate, and positive biopsy fraction) for a baseline mammogram.
Methods: We constructed a decision tree to model the possible outcomes of a baseline screening mammogram in women ages 35 to 65. We compared the single baseline screening mammogram decision with the no screening alternative. We used the Surveillance Epidemiology and End Results national cancer database as the primary input to …

Rule-Based Mamdani-Type Fuzzy Modeling Of Skin Permeability, Deepak R. Keshwani, David D. Jones, George E. Meyer, Rhonda M. Brand

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Two Mamdani type fuzzy models (three inputs–one output and two inputs–one output) were developed to predict the permeability of compounds through human skin. The models were derived from multiple data sources including laboratory data, published data bases, published statistical models, and expert opinion. The inputs to the model include information about the compound (molecular weight and octonal–H₂O partition coefficient) and the application temperature. One model included all three parameters as inputs and the other model only included information about the compound. The values for mole molecular weight ranged from 30 to 600 Da. The values for the log …

Evidence That The Nijmegen Breakage Syndrome Protein, An Early Sensor Of Double-Strand Dna Breaks (Dsb), Is Involved In Hiv-1 Post-Integration Repair By Recruiting The Ataxia Telangiectasia-Mutated Kinase In A Process Similar To, But Distinct From, Cellular Dsb Repair., Johanna A Smith, Feng-Xiang Wang, Hui Zhang, Kou-Juey Wu, Kevin Jon Williams, René Daniel

Kimmel Cancer Center Faculty Papers

Retroviral transduction involves integrase-dependent linkage of viral and host DNA that leaves an intermediate that requires post-integration repair (PIR). We and others proposed that PIR hijacks the host cell double-strand DNA break (DSB) repair pathways. Nevertheless, the geometry of retroviral DNA integration differs considerably from that of DSB repair and so the precise role of host-cell mechanisms in PIR remains unclear. In the current study, we found that the Nijmegen breakage syndrome 1 protein (NBS1), an early sensor of DSBs, associates with HIV-1 DNA, recruits the ataxia telangiectasia-mutated (ATM) kinase, promotes stable retroviral transduction, mediates efficient integration of viral DNA …

Parasite Pathoecology Of Salmon Pueblo And Other Chacoan Great Houses: The Healthiest And Wormiest Ancestral Puebloans, Karl Reinhard

Karl Reinhard Publications

Two fields of paleopathological investigation originated in the Southwest. Archaeoparasitology is the study of ancient parasite infection (Reinhard 1990, 1992b). It includes comparisons between time periods of single societies as well as comparisons of parasitism between different, contemporaneous cultures. For example, Fry (1980) compared Fremont and Anasazi parasitism, and also Archaic hunter-gatherer and ancestral Pueblo parasitism. All of these studies fall into the definition of archaeoparasitology.

By contrast, pathoecology is the reconstruction of relationships among behavior, environment, and disease organisms in the development of illness (Martinson et al. 2003; ReinhardandBuikstra2003; Reinhardet al. 2003; Santoro et al. 2003).1his field developed from …

Karl Reinhard Publications

Two small mummy bundles, found in a tomb at the Chillon River Valley, Lima Plains, Peru exist in the collections of the Museu Nacional, Rio de Janeiro, Brazil. They were donated to the collections at the beginning of the 20th century. A multidisciplinary team is now curating and studying them. CT scans confirmed both skeletons were of individuals less than one year old at death. One of the bundles is intact and will be preserved and displayed. The other one was partly decomposed and the authors received permission to unwrap it to analyze the bones in details. Mites and pollen …

A Child And His Fate: Tuberculosis, Perimortem Trauma And Mummification, Sheila M. M.De Souza, Karl J. Reinhard, Bernardo Tessarollo, Jose Fernando Cardona Zannier, Adauto Araujo

Karl Reinhard Publications

A male child, sitting, 7 years, circumferential deformation, skin marked by coiled fibers, nostril plugs, consistent with Aymara practices was CT scanned. Puppae in the skin suggest exposition of the body previous to the funeral. Dark brown color at the skin suggest blood perfusion. A broken area at the right frontal with the skin partially inside is suggestive of perimorten trauma. There were no bone debris inside the skull and the CT images show two confluent fractures defined by radiating lines extending beyond the missing bone surface. The right eyeball is projected out, the tongue is outside the mouth, the …

Pathoecology And The Future Of Coprolite Studies In Bioarchaeology, Karl J. Reinhard, Vaughn M. Bryant Jr.

Karl Reinhard Publications

Human coprolites currently provide an expanding array of information about the diet, health, and ecology of prehistoric people in the Southwest, but for many years coprolites were not recognized or preserved, or they were not considered important and thus were not saved (Bryant and Dean 2006). With the expansion of archaeological field work during the last half of the twentieth century archaeologists have increasingly explored the "complete" potentials of sites, including the collection and analysis of geomorphologic, botanical, and faunal data. In some ideal habitats (e.g., very dry or frozen) this includes exploring the scientific potential of human coprolite studies. …
