Extreme Ultraviolet Polarimetry With Laser-Generated High-Order Harmonics: Characterization Of Uranium, Nicole Brimhall

Theses and Dissertations

We developed an extreme ultraviolet (EUV) polarimeter, which employs laser-generated high-order harmonics as the light source. This relatively high-flux, directional EUV source has available wavelengths between 10 nm and 47 nm with easily rotatable linear polarization. The polarimeter has allowed us to characterize the optical constants of materials that may be useful for EUV optics. The instrument has a versatile positioning system and a spectral resolution of about 180, and we have demonstrated that reflectance as low as 0.1% can be measured repeatably at EUV wavelengths. We investigate the high harmonic source used for polarimetry measurements by documenting the spatial …

The Genome Scale Metabolic Model Of Cryptosporidium Hominis: Inv209, Niti Vanee

Theses and Dissertations

The apicomplexan Cryptosporidium is a protozoan parasite of humans and other mammals. Cryptosporidium species cause acute gastro-enteritis and diarrheal disease in healthy humans and animals, and cause life-threatening infection in immuno-compromised individuals such as people with AIDS. It has a one-host life cycle and invades intestinal epithelial cells causing diarrhea, or more rarely the pulmonary epithelium. Cryptosporidium carries out all the asexual reproductive stages like several other apicomplexans. Current annotation of this organism predicts it to contain 3884 genes of which only 1581 genes have predicted functions. By using a combination of bioinformatics analysis, biochemical evidence, and high-throughput data, a …

Chaperone Association With Telomere Binding Proteins, Amy Depcrynski

Theses and Dissertations

The Hsp90 chaperone complex associates with the telomerase enzyme, facilitating the assembly of the ribonucleoprotein complex. While previous data from our laboratory indicate that Hsp90 and p23 remain stably associated with (functionally active) telomerase, more recent experiments suggest that these chaperones associate with telomeres independent of telomerase, presumably through a specific interaction with telomere binding proteins. The current study examines the novel interactions between TRF2, TRF1, TIN2 and TPP1 and molecular chaperones (Hsp90, Hsp70, p23). In vitro and in cell experiments have shown an interaction between TRF1 and TRF2 and the molecular chaperones Hsp90 and Hsp70. Inhibition of Hsp90 using …

Leadership Development Of Registered Dietitians, Anne Marie Bigley Hunter

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

This study investigated leadership development of Registered Dietitians in nationally elected or appointed leadership positions of the American Dietetic Association. An explanatory sequential mixed method design: participant selection model was used collecting qualitative data after a quantitative phase. Demographic data were collected via a mailed survey questionnaire followed by, with consent, a web based validated Sentence Completion Test International- Maturity Assessment Profile Research Version (2) (SCTi- MAP) to determine their stage of leadership development. Of the 97 participants, 86% (n=83) responded to the survey questionnaire with 92% (n=79) rating the importance of dietitians being leaders as very important; 100% (n=83) …

Chemical And Isotopic Characterization Of Size-Fractionated Organic Matter From Cryoturbated Tundra Soils, Northern Alaska, Chunhao Xu, Laodong Guo, Chien-Lu Ping, Daniel M. White, Thomas D. Lorenson

Faculty Publications

Recent studies indicate a second layer of organic matter often accumulates in the lower active layer and upper permafrost in arctic tundra soils as a result of cryoturbation. In this study, cryoturbated organic matter was characterized using a combination of physical size fractionation and modern analytical techniques for elemental composition (C and N), stable isotopes (delta(13) C and delta(15)N), radiocarbon content (Delta(14)C), and molecular fingerprinting (pyrolysis-gas chromatography/mass spectrometry, Py-GC/MS). The results indicated that cryoturbated organic matter could be highly bioavailable. Soil organic matter (SOM) associated with fine sand particles was considered to be the organic carbon pool most sensitive to …

Throughout the history of the HIV epidemic, HIV-positive patients with relatively high CD4 counts and no clinical features of opportunistic infections have been classified as ‘‘asymptomatic’’ by definition and treatment guidelines. This classification, however, does not take into consideration the array of symptoms that an HIV-positive person can experience long before progressing to AIDS. This short report describes two international multi-site studies conducted in 2003 - 2005 and 2005 - 2007. The results from the studies show that HIV-positive people may experience symptoms throughout the trajectory of their disease, regardless of CD4 count or classification. Providers should discuss symptoms and …

Relationship Among Stress Of Labor, Support, And Childbirth Experience In Postpartum Mothers, Sasamon Srisuthisak

Theses and Dissertations

Background: Due to the profound and life-changing aspects of giving birth and to each woman’s individualized birthing experience, it is important to understand the myriad of factors that contribute to a positive childbirth experience. The aims of this study were to: (1) identify factors related to a positive childbirth experience; (2) to examine relationships among women’s perceptions and personal evaluations of their childbirth experience, stress associated with labor pain, support from the nursing staff, initial contact with the baby following birth, support from partners, education, age, and obstetric history; and (3) to identify predictors of a positive childbirth experience.

Sexual Selection In A Species With Exploded Leks: The White-Crowned Manakin (Pipra Pipra), Wendy P. Tori

Dissertations

Understanding what determines male reproductive success is central to sexual selection theory. The main goal of this dissertation was to examine the processes that shape female mate choice and male reproductive success in an exploded lek species: the White-crowned Manakin (Pipra pipra). The first chapter examined if females select males with certain genetic characteristics to gain indirect fitness benefits. Specifically, it tested whether females preferentially mate with unrelated males or males with high overall heterozygosity to increase the genetic diversity of their offspring. The second chapter examined if food resources within territories affect male mating success of territory …

Heterogeneity Effects On Flow And Transport Within A Shallow Fluvial Aquifer, Nicholas Engdahl

Earth and Planetary Sciences ETDs

The effects of aquifer heterogeneity on flow and transport are considered numerically at two scales using high resolution groundwater models. Heterogeneity effects on river loss were evaluated at the kilometer scale using stochastic, geostatistical models with grid cells on the order of several meters. It was found that river loss decreased directly with an increase in the extent of heterogeneity and that homogeneous approximations resulted in increased loss estimates. Heterogeneity effects on transport were simulated at the scale of several meters using a homogeneous approximation, traditional geostatistical models and a new integrated method of aquifer characterization. The integrated method combines …

The present invention concerns a novel α7 nicotinic receptor subunit isoform, α7-2. The α7-2 isoform contributes to novel acetylcholine receptors (AChRs) with pharmacological and biophysical properties distinct from those of wild-type α7-1-nAChRs and closely resembling those of α7-nAChRs found in intrinsic cardiac neurons and Type II α7-nAChRs of superior cervical ganglion neurons. Polynucleotides encoding the α7-2 isoform, vectors and genetically modified cells containing such polynucleotides are also provided. In addition, methods are provided for producing the α7-2 isoform as are methods of using such isoforms for screening compounds for activity at the nAChR.

P2x Antagonists Inhibit Styryl Dye Entry Into Hair Cells, M. A. Crumling, M. Tong, K. L. Aschenbach, L. Liu

University Faculty Publications and Creative Works

The styryl pyridinium dyes, FM1-43 and AM1-43, are fluorescent molecules that can permeate the mechanotransduction channels of hair cells, the sensory receptors of the inner ear. When these dyes are applied to hair cells, they enter the cytoplasm rapidly, resulting in a readily detectable intracellular fluorescence that is often used as a molecular indication of mechanotransduction channel activity. However, such dyes can also permeate the ATP receptor, P2X2. Therefore, we explored the contribution of P2X receptors to the loading of hair cells with AM1-43. The chick inner ear was found to express P2X receptors and to release ATP, similar to …

Faculty Publications

Selective logging is an extensive land use in the Brazilian Amazon region. The soil–atmosphere fluxes of nitrous oxide (N2O), nitric oxide (NO), methane (CH4), and carbon dioxide (CO2) are studied on two soil types (clay Oxisol and sandy loam Ultisol) over two years (2000–01) in both undisturbed forest and forest recently logged using reduced impact forest management in the Tapajos National Forest, near Santarem, Para, Brazil. In undisturbed forest, annual soil–atmosphere fluxes of N2O (mean ± standard error) were 7.9 ± 0.7 and 7.0 ± 0.6 ng N cm−2 h−1 for the Oxisol and 1.7 ± 0.1 and 1.6 ± …

Increasing The Reliability Of Ecological Models Using Modern Software Engineering Techniques, Robert M. Scheller, Brian R. Sturtevant, Eric J. Gustafson, Brendan C. Ward, David J. Mladenoff

Environmental Science and Management Faculty Publications and Presentations

Modern software development techniques are largely unknown to ecologists. Typically, ecological models and other software tools are developed for limited research purposes, and additional capabilities are added later, usually in an ad hoc manner. Modern software engineering techniques can substantially increase scientific rigor and confidence in ecological models and tools. These techniques have the potential to transform how ecological software is conceived and developed, improve precision, reduce errors, and increase scientific credibility. We describe our re-engineering of the forest landscape model LANDIS (LANdscape DIsturbance and Succession) to illustrate the advantages of using common software engineering practices.

Exploring The Methylation Status Of Rai1 And The Rai1 Consensus Binding Sequence, Eri Kamura

Theses and Dissertations

Smith Magenis Syndrome (SMS) is a multiple congenital anomalies/ mental retardation disorder caused by deletion or mutation of the RAI1 gene on chromosome 17p11.2. The majority of patients with SMS phenotypes have a deletion or mutation of RAI1. However, some patients have been observed with SMS-like phenotypes and yet have no deletions or mutations in the RAI1 gene. One possible explanation could be aberrant methylation of RAI1 since RAI1 is present and yet may be silenced. In order to study this possibility, patient cell lines were treated with 5-Aza-2’-deoxycytidine. RNA was extracted and real-time PCR was used to check the …

Functional Folate Receptor Alpha Is Elevated In The Blood Of Ovarian Cancer Patients., Eati Basal, Guiti Z. Eghbali-Fatourechi, Kimberly R. Kalli, Lynn C. Hartmann, Karin M. Goodman, Ellen L. Goode, Barton A. Kamen, Philip S. Low, Keith L. Knutson

Department of Chemistry Faculty Publications

Background

Despite low incidence, ovarian cancer is the fifth leading cause of cancer deaths and it has the highest mortality rate of all gynecologic malignancies among US women. The mortality rate would be reduced with an early detection marker. The folate receptor alpha (FRα) is one logical choice for a biomarker because of its prevalent overexpression in ovarian cancer and its exclusive expression in only a few normal tissues. In prior work, it was observed that patients with ovarian cancer had elevated serum levels of a protein that bound to a FRα-specific monoclonal antibody relative to healthy individuals. However, it …
