Tnf(Alpha)-Dependent And Tnf(Alpha)-Independent Activation Of Macrophage Effector Function, Annette R. Clemons-Miller May 1998

Tnf(Alpha)-Dependent And Tnf(Alpha)-Independent Activation Of Macrophage Effector Function, Annette R. Clemons-Miller

Electronic Theses and Dissertations

Tumor necrosis factor α (TNFα) is a pleiotropic cytokine that is predominantly produced by activated macrophages. The effects of TNFα are as diverse as the cells with which it interacts, e.g., stimulating fibroblast growth, exerting cytotoxic/cytostatic; activity against various human and murine cell lines, promoting inflammation through upregulation of endothelial adhesion molecules and IL-8 production. Yet TNFα is best known, and in fact was originally described, for its role in the bacterial-induced hemorrhagic necrosis of tumors and exacerbation of septic shock in which aberrant TNFα production leads to vascular collapse, cachexia, multiple organ failure, and ultimately death in as many …

The Influence Of A Human Repetitive Dna On Genome Stability, Eugenia L. Posey May 1998

The Influence Of A Human Repetitive Dna On Genome Stability, Eugenia L. Posey

Electronic Theses and Dissertations

A uniquely human interspersed repetitive DNA sequence family, the L2Hs, are highly polymorphic in human genomes. Several features of interspersed repeated DNA may contribute to the instability observed. Certain motifs (direct repeats, palindromes, and inverted repeats) comprising L2Hs elements may adopt unusual secondary structures such as cruciforms or hairpins. These motifs have been associated with features of genome instability in recombination, insertions and deletions. The L2Hs elements also are AT-rich (76%) compared to the bulk of human DNA (52%). That their dynamic nature (i.e. polymorphisms) may arise from recombination, insertions and deletions has led to the hypothesis that the L2Hs …

Effects Of Preservation Methods, Parasites, And Gut Contents Of Black Flies (Diptera: Simuliidae) On Polymerase Chain Reaction Products, D. A. Koch, G. A. Duncan, T. J. Parsons, K. P. Pruess, T. O. Powers May 1998

Effects Of Preservation Methods, Parasites, And Gut Contents Of Black Flies (Diptera: Simuliidae) On Polymerase Chain Reaction Products, D. A. Koch, G. A. Duncan, T. J. Parsons, K. P. Pruess, T. O. Powers

Department of Entomology: Faculty Publications

Molecular analysis of biological specimens usually requires extraction of high-molecular-weight DNA free of foreign DNA contaminants. DNA was extracted from black flies at different life stages that had been preserved by 4 methods: larvae and adults in ethanol, larvae in Carnoy’s solution, adults on card-points, and adults hand-swatted and sun-dried. Using specific primers for the mitochondrial ND4 gene, a 257-bp amplicon was obtained from specimens preserved by ethanol, card-point mounting, and sun-drying. Successful amplification often required DNA dilutions ≥ 1:20 (<1–10 ng). DNA from specimens preserved in Carnoy’s solution (ethanol: acetic acid, 3:1) yielded degraded DNA, resulting in fewer successful amplifications. Parasitic nematodes and, to a lesser extent, gut contents resulted in extra products when amplified with randomly amplified polymorphic DNA (RAPD) primers. Sufficient DNA was extracted from the head of a larva for a successful polymerase chain reaction (PCR), eliminating the need to remove the contaminating gut and parasites.

The Effects Of Conjoint Behavioral Consultation And A Structured Homework Program On Math Completion And Accuracy In Junior High Students, Robin K. Weiner, Susan M. Sheridan, William R. Jenson

Department of Educational Psychology: Faculty Publications

The effects of conjoint behavioral consultation (CBC) and a structured homework program on math homework completion and accuracy in junior high school students (grades seven through nine) who were at risk for academic failure were investigated. A multiple baseline design across five participants was utilized. Follow-up data were collected approximately one month after CBC was completed, to assess maintenance over time. Four of the five students improved their completion rates during treatment. Accuracy rates increased during treatment, but to a lesser degree. At follow-up, three of the five students maintained or improved gains they made during treatment. One student who …

Two New Subspecies Of Bats Of The Genus Sturnira, Hugh H. Genoways May 1998

Two New Subspecies Of Bats Of The Genus Sturnira, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The last systematic review of the yellow-shouldered bats of the Neotropical genus Sturnira in the Lesser Antilles was in 1976 (Jones and Phillips, 1976). At that point in time, two species--Sturnira lilium and Sturnira thomasi--were known from these islands. Sturnira lilium was represented by five subspecies, beginning with Trinidad and moving northward, these subspecies were lilium on Trinidad (Goodwin and Greenhall, 1961), paulsoni on St. Vincent (de Ia Torre and Schwartz, 19661, luciae on St. Lucia (Jones and Phillip, 19761, zygomaticus on Martinique (Jones and Phillips, 1976), and angeli on Dominica (de la Tom, 1966).

Biological Characterization Of Rev Variation In Equine Infectious Anemia Virus, Michael Belshan, Matthew E. Harris, Anne E. Shoemaker, Thomas J. Hope, Susan Carpenter May 1998

Biological Characterization Of Rev Variation In Equine Infectious Anemia Virus, Michael Belshan, Matthew E. Harris, Anne E. Shoemaker, Thomas J. Hope, Susan Carpenter

Nebraska Center for Virology: Faculty Publications

Sequence analysis identified significant variation in the second exon of equine infectious anemia virus (EIAV) rev. Functional analysis indicated that limited amino acid variation in Rev significantly altered the export activity of the protein but did not affect Rev-dependent alternative splicing. EIAV Rev can mediate export through two independent cis -acting Rev-responsive elements (RREs), and differences among Rev variants were more pronounced when both RREs were present. Variation in Rev may be an important mechanism for regulation of virus replication in vivo and may contribute to changes in clinical disease.

Preliminary Phylogenetic Analysis Of Subfamilies Of The Proteocephalidea (Eucestoda), Amilcar Arandas Rego, Alain De Chambrier, Vladimira Hanzelová, Eric P. Hoberg, Tomás Scholz, Peter Weekes, Marc Zehnder

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cladistic analysis based on comparative morphology was used to examine the subfamily-level relationships within the cestode order Proteocephalidea. A single most parsimonious tree (70 steps, CI = 0.571; RC = 0.295; HI = 0.471) is consistent with monophyly for the Proteocephalidea and showed a relatively high consistency at the family level with the diagnosis of two major subclades. Unambiguous support for a Proteocephalidae subclade, including the Corallobothriinae, Proteocephalinae, Gangesiinae and Sandonellinae, and a Monticelliidae subclade, including the Marsypocephalinae, Zygobothriinae, Monticelliinae, Rudolphiellinae, Ephedrocephalinae and Othinoscolecinae was evident. Two subfamilies, the Acanthotaeniinae (historically in the Proteocephalidae) and Nupeliinae (historically in the Monticelliidae), …

Predicting Family Strength In Families Caring For Children With Disabilities, Katrina J. F. Ericson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research sought to identify factors that might be useful in helping to predict family strengths in families caring for a child with a disability. Based on the ABCX model designed for families in crisis, this research examined severity of child's disability (A); the family's existing resources of household income, education of the mother, and mother's marital status (B); the family's perception of family resources, family support, and parenting stress (C); and how these influence family strength (X) over time. In relation to the ABCX model, it was hypothesized that the aforementioned constructs would be associated with each other, and …

Acculturation Of A Mexican-American Male Population And Gender Role Conflict, Gary Evan Leka May 1998

Acculturation Of A Mexican-American Male Population And Gender Role Conflict, Gary Evan Leka

Theses and Dissertations - UTB/UTPA

This study examined the effects of different modes of acculturation upon self reported levels of gender role conflict, and explored the relationship among acculturative stress, the concepts of Machismo and Familism and gender role conflicts. Hispanic males (N = 164) from a university with an 90% Hispanic enrollment were surveyed. Low Bicultural subjects differed significantly upon the factors of restrictive emotionality and restrictive affectionate behavior between men than other modes of acculturation. Machismo was found to be significantly related to stress and conflicts with gender roles, while Familism was found to be related to two of the patterns of gender …

Evaluation Of The Lady Free Biotester® In Determining The Fertile Period, Richard J. Fehring, Nancy Gaska

College of Nursing Faculty Research and Publications

Small hand-held microscopes have been developed for self-observation of salivary ferning patterns to detect the fertile time of a woman’s menstrual cycle. The purpose of this study was to evaluate one such microscope, the Lady Free Biotester®, by comparing it with the self-observation of cervical-vaginal mucus and with the self-detection of luteinizing hormone (LH) in the urine. Twelve natural family planning teachers (average age 34.6 years) observed their cervical-vaginal mucus, tested their urine for LH, and observed salivary and cervical-vaginal mucus ferning patterns (with the Lady Free Biotester) for two menstrual cycles. Data indicated that there was a …

The Biology Of Xenopus By R. C. Tinsley And H. C. Kobel, Rafael O. De Sá May 1998

The Biology Of Xenopus By R. C. Tinsley And H. C. Kobel, Rafael O. De Sá

Biology Faculty Publications

The Biology of Xenopus presents a summary of current knowledge about a single genus resulting from a symposium held at the Zoological Society of London in September 1992. This approach to summarizing available information has also been taken for other taxa, such as Atelopus (Lotters, 1996). However, the task of compiling data for Xenopus is enormous relative to any other amphibian group, because Xenopus laevis has become a model system for molecular and development research (Cannatella and de Sa, 1993). Unfortunately, most of our knowledge of Xenopus is biased toward this single species. There are about 20 recognized species of …

Undergraduate Honors Capstone Projects

Transmissible Spongiform Encephalopathies (TSE's) are neurodegenerative disorders characterized by a long generation time, spongy degeneration in the cerebral gray matter, neuronal loss and proliferation and hypertrophy of glial cells. An abnormal form of the prion protein (PrP) plays a major part in TSE pathogenesis and has been hypothesized to be the only component of the infectious agent. Some animals exposed to scrapie, the TSE affecting sheep and goats, seem to be resistant to development of the disease. Alleles encoding amino acid substitutions at codons 136 (A/V) and 171 (Q/R/H) have been associated with scrapie resistance. Other amino acid substitutions at …

Obesity: Environment Vs. Genetics, Kammi Marie Reeder Hansen

Undergraduate Honors Capstone Projects

The prevalence of overweight and obese individuals is rising. Between 1980 and 1990 there was an 8% increase in the prevalence of obesity. Obesity is associated with many diseases such as hypertension, type 2 diabetes, heart disease and cancer. Over $39 billion dollars is spent annually on the illnesses associated with obesity. Our American culture has been blamed for the rise in obesity, yet there are obviously many people living in the American culture that are not obese. Researchers have turned to genetics to explain this phenomenon. This article will examine the many environmental factors that contribute to obesity and …

Parameter Estimation Using Artificial Neural Network And Genetic Algorithm For Free-Product Migration And Recovery, J. Morshed, Jagath J. Kaluarachchi May 1998

Parameter Estimation Using Artificial Neural Network And Genetic Algorithm For Free-Product Migration And Recovery, J. Morshed, Jagath J. Kaluarachchi

Civil and Environmental Engineering Faculty Publications

Artificial neural network (ANN) is considered to be a universal function approximator, and genetic algorithm (GA) is considered to be a robust optimization technique. As such, ANN regression analysis and ANN-GA optimization techniques can be used to perform inverse groundwater modeling for parameter estimation. In this manuscript the applicability of these two techniques in solving an inverse problem related to a light-hydrocarbon-contaminated site is assessed. The critical parameters to be evaluated are grain-size distribution index α and saturated hydraulic conductivity of water Ksw, since these parameters control free-product volume predictions and flow. A set of published data corresponding to a …

Identification Of A Genetic Marker For Litter Size In Sheep, Olivia Price May 1998

Identification Of A Genetic Marker For Litter Size In Sheep, Olivia Price

Undergraduate Honors Capstone Projects

The purpose of this experiment was to determine if the estrogen receptor gene (ESR) could be used as a genetic marker for litter size in sheep. The estrogen receptor gene was chosen because it has been successfully used as a genetic marker for litter size in swine. In this study, DNA dilutions from two experimental flocks, totaling approximately 200 animals, were used. Amplification of exon 1/intron 1 of the ESR gene was performed using PCR. Initial results indicated a polymorphism in the gene when cut with the restriction enzyme Ava ll. It appeared that the gene contained a deletion with …

A Comparison Of Selected Measures Of Academic Performance And Student Behavior At Bryan Senior High School Before And After Implementation Of Block Scheduling, Margaret M. Naylon May 1998

A Comparison Of Selected Measures Of Academic Performance And Student Behavior At Bryan Senior High School Before And After Implementation Of Block Scheduling, Margaret M. Naylon

Student Work

This study examines the effects of a restructuring effort: the implementation of block scheduling in an Urban Nebraska public high school. Scheduling is a valuable resource for school improvement. Scheduling is frequently overlooked, even though it is more often the structure of an organization than the inadequacies of the people who work within it that cause the problem (Bogdan, 1992). Despite research findings which indicate the traditional schedule may not be the most effective, most American schools are organized in the same pattern as they have been for the past seventy years (Carroll, 1990). Block scheduling is a relatively new …

Determination Of Intracellular Glutathione Concentration Using Monobromobimane, Ryan R. Owens May 1998

Determination Of Intracellular Glutathione Concentration Using Monobromobimane, Ryan R. Owens

Undergraduate Honors Capstone Projects

Asbestos is a general term for a group of fibrous silicates. Diseases such as asbestosis, bronchogenic carcinoma, and mesothelioma have been linked to asbestos exposure (1,2). The 1 two classes of asbestos, serpentine and amphibole, are distinguished by differences in structure and chemical composition (3). The amphibole crocidolite contains 27% iron while the serpentine chrysotile contains only 2-3% iron. The higher iron content of crocidolite is proposed to be a contributing factor for a much higher incidence of cancer with crocidolite exposure compared with chrysotile exposure ( 4). Iron mobilized intracellularly from asbestos fibers may participate in the formation of …

I visited Primary Children's Medical Center on a fresh snow morning near the beginning of last winter. The hospital was not where it had been in my childhood, a quiet neighborhood in "the avenues" section of Salt Lake City; several years ago the hospital moved to a new location farther east on the Wasatch Mountain foothills, near the University of Utah Medical Center. The old brick building now sits sedate and empty at the top of a shaded hill. My memory of the old hospital is as a bright and oppressive place, full of the stuff of life and death. …

Genetic Differentiation Between Populations Of Erythronium Grandiflorum As Contributed By Isolation By Distance Vs Isolation By Phenology, Ashley Noel Egan May 1998

Genetic Differentiation Between Populations Of Erythronium Grandiflorum As Contributed By Isolation By Distance Vs Isolation By Phenology, Ashley Noel Egan

Undergraduate Honors Capstone Projects

Erythronium grandiflorum, a montane herb, was sampled to address the degree of genetic differentiation allocated to populations by isolation by distance vs. the amount of genetic differentiation produced by different flowering times, or isolation by phenology. Isozyme analysis was used to obtain genetic data from five populations of E. grandiflorum, three comprising the elevational scale which addressed isolation by phenology, and three comprising the spatial scale which explored isolation by distance. Based on the small sample size used in this study, the elevational scale shows a slightly higher degree of genetic differentiation than the spatial scale. Future studies …

The Role Of Ferritin In Iron Regulation, Rick White Obray May 1998

The Role Of Ferritin In Iron Regulation, Rick White Obray

Undergraduate Honors Capstone Projects

Iron plays a critical role in biological systems. Its variable redox properties make it a tremendously versatile element. It is involved in numerous cellular processes including; oxygen transport, nucleotide synthesis, nitrogen fixation, electron transport and a host of metabolic reactions. Without it, nearly all life would cease to function. However, under certain circumstances iron can be extremely detrimental to biological systems and has been linked to numerous pathologies, including cancer, diabetes, Parkinson's disease, Alzheimer's and atherosclerosis. In the presence oxygen, Fe(II) is rapidly oxidized to Fe(III), and oxygen is reduced to potentially deleterious oxygen radicals (1). These radicals, especially the …

Undergraduate Honors Capstone Projects

The spatial redistribution of organisms in an ecosystem is often a complex process. Many ecosystems exhibit spatial complexity on a broad range of scales, driven by the physical environment and biotic interactions [1]. As different species aggregate and disperse in spatially complex ways, even an initially uniform environment will soon evolve spatial heterogeneity.

Philip Sober Controlling Philip Drunk: "Buchanan V. Warley" In Historical Perspective, David E. Bernstein

Vanderbilt Law Review

In Buchanan v. Warley the Supreme Court found that a Louisville, Kentucky, residential segregation ordinance was unconstitutional because it interfered with the Fourteenth Amendment right to own and dispose of property and could not be justified as a police power measure.' The Buchanan decision came at a crucial juncture in the history of American race relations. Several cities in the southern and border states had recently passed residential segregation ordinances, and other cities were poised to follow suit if the Supreme Court ruled that such ordinances were constitutional. Several northern cities were considering adopting residential segregation laws as well,' and …
