Usage And Development Of Molecular Markers For Investigation Of The Population And Ecological Genetics Of Bromus Tectorum L., Keith R. Merrill

Theses and Dissertations

This thesis includes two studies: The first examined patterns of neutral genetic diversity within Bromus tectorum L. across the IMW region, and uses patterns of microsatellite (SSR) genotype distribution to make inferences about the respective roles of adaptively significant genetic variation, adaptive phenotypic plasticity, and facultative outcrossing in the ongoing invasion and recent range expansion of B. tectorum. It has been previously demonstrated that, due to extremely low outcrossing rates, it is possible to characterize individual genotypes of this species using four SSR loci. We sampled 20 individuals from each of 96 B. tectorum populations (classified by region and …

Effects Of Water Quality On Genetic Variation On The Brackish-Water Rotifer Brachionus Plicatilis, Kayla I. Hinson^, Elizabeth J. Walsh*

COURI Symposium Abstracts, Spring 2011

Impacts of water quality on the genetic structure of aquatic organisms have not been well characterized. Unfavorable conditions may result in loss of species diversity and/ or select for tolerant genotypes. We investigated whether aquatic pollutants affect the genetic diversity of the rotifer Brachionus plicatilis, common in saline systems. We predict that the genetic diversity of B. plicatilis will decrease with lower water quality. An urban population (Ascarate Lake, El Paso Co., TX) was compared with a non-impacted population (Figure 8 Lake, Bottomless Lakes, NM). Basic water chemistry parameters were measured along with heavy metals concentrations. Genetic variation is …

Preliminary Ecological Assessment Of Stream Quality In The Sacramento Mountains, New Mexico., Ector M. Martell^, Bianca C. Luong^, Vanessa Lougheed*

COURI Symposium Abstracts, Spring 2011

Pollution in freshwater ecosystems has reduced the ability of freshwater habitats to host a variety of organisms. Algal biomass and macroinvertebrate assemblages can reflect stream quality, due to their rapid response to nutrients and limited dispersal ability, respectively. In this study, we used algae and macroinvertebrates as bio-indicators of river quality in the Sacramento Mountains of New Mexico, which is largely forested with some low-level development and cattle grazing. All of our sites (n = 3) had a macroinvertebrate Ephemeroptera, Plecoptera, Trichoptera (EPT) index of 50% or greater, which suggest high quality conditions in the river. More specifically, all sites …

Expression And Purification Of Recombinant Ledgf/P75, Ivonne R. Reyes^, Daniel Reyes, Manuel Llano*

COURI Symposium Abstracts, Spring 2011

HIV infection requires the integration of a DNA copy of the viral genome into the host chromosome. The cellular protein LEDGF/p75 has an essential role in this process. Different cellular proteins interact with LEDGF/p75, but the significance of these interactions for HIV infection is unknown. To further characterize these protein interactions, we will use recombinant LEDGF/p75 wild type (WT) and mutants. LEDGF/p75 WT was PCR amplified and cloned N- terminally fused to glutathione S-transferase (GST). This expression plasmid was later used to generate deletion mutants targeting different LEDGF/p75 functional domains. These constructs were transformed into E. coli Rosetta. Optimal conditions …

Characterization Of Promoter Specific Effects Displayed By Beta-Catenin And Fkbp52 In The Regulation Of Ar, Karen Olivares^, Marc B. Cox*, Cheryl Storer

COURI Symposium Abstracts, Spring 2011

One of the most interesting topics in steroid hormone research is examining the influence of regulators of the steroid hormone signaling pathways. By identifying and understanding the relationship between these regulators on events of transcriptional regulation, receptor localization, and degradation events, we can target these regulators to enhance or decrease their influence on the steroid hormone receptors’ activities within the cell. Increased transcription by the Androgen Receptor has been implicated in several prostate cancer studies. Two proteins in particular, FKBP52 and β-Catenin, are of interest to our group, to examine for potential interaction in signaling cascades promoting prostate cancer.  β-Catenin’s …

Effects Of Cerium Oxide Nanoparticles On Glycine Max Grown In Hydroponics, Alyssa De La Rosa^, Jose Peralta, Jeff Terry, Jorge Gardea-Torresdey*

COURI Symposium Abstracts, Spring 2011

Cerium oxide nanoparticles (NPs) or nanoceria have a high level of UV absorption and antioxidant behavior, making them great candidates for sun screens, beauty products, and in treating cancer and glaucoma. The increased use of these NPs underscores the importance of understanding their environmental fate and toxicity. So far, information about nanoceria toxicity to plants is scarce. The objectives of this study are to determine the effect of CeO2 NPs on soybean (Glycine max) plant growth and monitor their uptake, deposition, and biotransformation. Soybean plants were treated for 14 days in a modified Hoagland solution containing varying concentrations …

Structural Study Of Mcry2: A Circadian Rhythm Regulator, Brenda L. Rodarte^, Gustavo A. Avila, Adrian S. Enriquez, Nicolas D. Silva, Tiffany H. Blankenship, Erquan Eric Zhang*, Chuan Xiao*

COURI Symposium Abstracts, Spring 2011

A circadian clock is a 24 hour biological rhythm that regulates physiological, psychological and behavioral processes in living organisms. Understanding the regulation mechanism of such circadian rhythms can have great impact in certain diseases such as sleeping disorders and cancers. There are many genes regulating circadian rhythms in different species. Cryptochromes (CRY) are photosensory receptors mediating light regulation of growth and development in certain species. Mouse cryptochrome protein mCRY2 has been found to encode a blue light photoreceptor and is important for mice circadian rhythm. The main goal of the project is to determine the atomic structure of mCRY2, via …

Modeling Of Solvent Electrostatic Effects, Jose A. Rodriguez Lopez^, Luis Basurto, Tunna Baruah*

COURI Symposium Abstracts, Spring 2011

The photo-induced charge-transfer process is fundamental to light harvesting in organic donor-acceptor systems. The process is often enhanced when the system is in a polar solvent. The aim of this project is to create a simple, discrete model containing dipoles that can explain the solvent effects, where only dipole-dipole solvent interaction is considered. The goal is to reduce computational complexities and cost. We create a grid of solvents (water) which mimic the solvent’s density; and put one solute (a light-harvesting triad of β-carotene, porphyrin, and C60) at the grid’s center, keeping the grid points 1.5 times the Van der Waal …

Screening Of Metal-Based Azole Derivatives Antiparasitic Activity On Trypanosoma Cruzi And Leishmania Major, Teresia A. Carreon^, Linda Herrera, Miguel Vasquez, Roberto A. Sanchez-Delgado, Rosa A. Maldonado*

COURI Symposium Abstracts, Spring 2011

The trypanosomatids Leishmania major and Trypanosoma cruzi are parasites that affect millions of people worldwide. Leishmaniasis is naturally transmitted via sandflies while T. cruzi is transmitted by kissing bugs. Due to immigration and deployment to endemic regions, lack of screening in blood banks and climatic changes these neglected diseases have become a growing health concern in the United States. The lack of vaccines to prevent/treat the diseases and the toxicity of current treatments supports the need for new drug treatments. Azole compounds inhibit the sterol synthesis pathway of these parasites, which has been validated as a drug target. T.cruzi epimastigote …

Apparent Competition With Bromus Tectorum Through Pyrenophora Semeniperda Reduces Establishment Of Native Grasses, Katherine Temus Merrill

Theses and Dissertations

Contributing to the success of Bromus tectorum in the Intermountain West may be a mechanism called apparent competition, which occurs when one species increases the pressure of a consumer on a second species. This indirect interaction has been documented only a few times in invasive plant systems, and never in a fungal pathosystem. We examined the effects of the invasive annual Bromus tectorum and predation by the seed pathogen Pyrenophora semeniperda on seedling emergence and survival for two native grasses (Pseudoroegneria spicata and Elymus elymoides), by manipulating B. tectorum densities and P. semeniperda inoculum loads in randomized plots. …

Information Literacy, Collaboration, And Teacher Education, Cindy Kovalik, Mary Lee Jensen, Barbara Schloman, Mary Tipton

Communications in Information Literacy

Information literacy is a critical component of a 21st century education. Teacher educators are confronted with teaching about information literacy on two levels: Not only do pre-service teachers need to become proficient in IL skills for their own success, they also need to learn how to teach their future students to become information literate (Branch, 2003; Carr, 1998; Hinchcliffe, 2003). In an effort to determine the extent to which teacher education programs incorporate information literacy instruction, researchers at a large Midwestern university conducted a survey of teacher education faculty in selected states. The survey sought to gather data related to …

Developing Countries, Vaccine Access And Influenza Outbreaks: Ethics And Global Health Governance When Facing A Pandemic, Shawn Smallman

International & Global Studies Faculty Publications and Presentations

The threat posed by influenza pandemics raises serious ethical issues, as well as questions of global health governance. In order to create pre-pandemic vaccines, global health authorities need access to virus from regional outbreaks. But because the countries where these outbreaks occur are unlikely to benefit from the vaccine, they are sometimes reluctant to share this seed stock, and may try to make proprietary arrangements with pharmaceutical companies, as briefly occurred in Indonesia. Although these arrangements may increase developing countries' access to vaccine, they hamper the global cooperation necessary to prepare for influenza outbreaks. Developing countries, in contrast, point to …

A Proteolytic Process To Simulate The Mechanics Of Disc Dengeration In Bovine Cadaveric Tissue, Timothy A. Bishop

Theses and Dissertations

Purpose. The present work hypothesized that proteolytic dissolution of intervertebral discs could induce biomechanical change comparable to the change observed in natural disc degeneration. A method to do such could be utilized for in vitro research where intersample differences in geometry and chemical makeup render it difficult to compare and aggregate results into generalized conclusions.
Methods. Forty-one bovine coccygeal intervertebral discs were isolated with individual functional spinal units. Samples were loaded in three modes: compression/tension, flexion/extension, and axial rotation. The anulus fibrosus of each disc was injected with 200µl trypsin or fetal bovine serum (control) and incubated for an allotted …

Developing Methods To Assess The Potential Effects Of Global Climate Change On Deer Creek Reservoir Using Water Quality Modeling, Reed Earl Chilton

Theses and Dissertations

To evaluate the potential impacts of future climate change on a temperate reservoir, I used a calibrated water quality and hydrodynamic model validated using three years of data (2007-2009) from Deer Creek Reservoir (Utah). I evaluated the changes due to altered air temperatures, inflow rates, and nutrient loads that might occur under Global Climate Change (GCC). I developed methods to study GCC on reservoirs. I produced Average Water Temperature Plots, Stratification Plots, and Total Concentration Plots. Average Water Temperature Plots show the sensitivity of the water temperature to various parameters. Stratification Plots quantify stratification length and strength as well as …

Culvert Roughness Elements For Native Utah Fish Passage: Phase I, Lindsay D. Esplin

Theses and Dissertations

Culverts can increase stream velocities as a result of reduced waterway areas and prevent upstream passage of small non-salmonid fish such as the Native Utah Leatherside chub (Gila copei) and Longnose dace (Rhinichthyscataractae). To mitigate this problem, current culvert design standards for fish passage match sustained fish swim speeds with average cross sectional velocity through the culvert. Such policies dictate relatively large barrels and do not recognize the role of reduced velocity zones near culvert boundaries. Obstacles and streambed substrate create turbulent regions with lower velocity zones that can increase upstream fish passage. A comparison of …
