Methamphetamine-Induced Conditioned Place Preference In Adolescent Male And Female Mice Of Two Strains, Andre Bevil Toussaint

Theses and Dissertations

We used a conditioned place preference paradigm to test the rewarding effects of methamphetamine (1mg/kg) in adolescent male and female mice of two strains. We found that methamphetamine induced conditioned place preference in female C57Bl/6 and male 129/SvEv mice, but not female 129/SvEv or male C57Bl/6 mice.


Raman Spectroscopy Based Validation For Handheld Non-Invasive Glucose Measurement, Dong Jae Joo Aug 2017

Raman Spectroscopy Based Validation For Handheld Non-Invasive Glucose Measurement, Dong Jae Joo

Theses and Dissertations

Diabetes mellitus has been steadily increasing for the past three decades and has been one of the major causes of death. Diabetes may develop serious complications as well. Even though diabetes can be controlled without developing severe complications by steady checking of glucose level, the physical pain in pricking fingers and the emotional distress associated with using conventional invasive glucose meter make diabetics neglect self-monitoring of blood glucose. Hence, the improvement of non-invasive glucose measurement technology could give a huge effect on diabetes patient for not only improving health but also an economic benefit. However, no non-invasive glucose monitoring device …

Ecological Niche Modeling Of The Genus Papio, Amanda J. Fuchs

Theses and Dissertations

Ecological niche modeling investigates how climatic variables have influenced taxonomic diversity in Papio. Models performed well suggesting climatic variables influence the distribution of baboon species. Niche overlap among all possible pairs of taxa determined that species exhibited significantly different niches. The results of these models support a parapatric speciation scenario.


The Role Of The Therapeutic Alliance On The Successful Outcome Of Transfers In Marriage And Family Therapy Cases, Melanie Louise Cox Aug 2017

The Role Of The Therapeutic Alliance On The Successful Outcome Of Transfers In Marriage And Family Therapy Cases, Melanie Louise Cox

Theses and Dissertations

The transfer of cases is common in the practice of Marriage and Family Therapy (MFT). This is especially true in training clinics, where student interns regularly graduate and transfer their cases to students still in the program. Although some research has examined the effect of transferring cases of individual psychotherapy on the success of therapy outcome, little research has examined transfer cases in MFT settings. The transfer process can be conceptualized as a rupture in the therapeutic alliance. From this perspective, a strong therapeutic alliance may mitigate the negative impact of the rupture. Consequently, it was hypothesized that a strong …

Characterizing The Fate And Mobility Of Phosphorus In Utah Lake Sediments, Matthew Chambers Randall

Theses and Dissertations

An increasing number of lakes worldwide are impacted by eutrophication and harmful algal blooms due to nutrient inputs. Utah Lake is a unique eutrophic freshwater lake that is naturally shallow, turbid, and alkaline with high dissolved oxygen levels. Recently, the Utah Division of Water Quality has proposed a new limitation of phosphorus (P) loading to Utah Lake from wastewater treatment plants in an effort to mitigate eutrophication. However, reducing external P loads may not lead to immediate improvements in water quality due to the legacy pool of nutrients in lake sediments. The purpose of this study was to characterize the …


The Effect Of Cocoa Flavanols On Β-Cell Mass And Function, Thomas John Rowley Aug 2017

The Effect Of Cocoa Flavanols On Β-Cell Mass And Function, Thomas John Rowley

Theses and Dissertations

A hallmark of type 2 diabetes (T2D) is β-cell dysfunction and the eventual loss of functional β-cell mass. Therefore, mechanisms that improve or preserve β-cell function could be used to improve the quality of life of individuals with T2D. Studies have shown that monomeric, oligomeric and polymeric cocoa flavanols have different effects on obesity, insulin resistance and glucose tolerance. We hypothesized that these cocoa flavanols may have beneficial effects on β-cell function. INS-1 832/13 derived β-cells and primary rat islets cultured with a monomeric catechin-rich cocoa flavanol fraction demonstrated enhanced glucose-stimulated insulin secretion, while cells cultured with total cocoa extract, …


Cell-Free Synthesis Of Proteins With Unnatural Amino Acids: Exploring Fitness Landscapes, Engineering Membrane Proteins And Expanding The Genetic Code, Song Min Schinn Aug 2017

Cell-Free Synthesis Of Proteins With Unnatural Amino Acids: Exploring Fitness Landscapes, Engineering Membrane Proteins And Expanding The Genetic Code, Song Min Schinn

Theses and Dissertations

Unnatural amino acids (uAA) expand the structural and functional possibilities of proteins. Numerous previous studies have demonstrated uAA as a powerful tool for protein engineering, but challenges also remain. Three notable such challenges include: (1) the fitness of uAA-incorporated proteins are difficult to predict and time-consuming to screen with conventional methods, (2) uAA incorporation in difficult-to-express proteins (e.g. membrane proteins such as G-protein coupled receptors) remain challenging, and (3) the incorporation of multiple types of uAA are still limited. In response, we pose cell-free protein synthesis (CFPS), a rapid and versatile in vitro expression system, as a platform to explore …


Electrophilic Catalysis Using Heterobimetallic Complexes, Whitney Kaye Walker Aug 2017

Electrophilic Catalysis Using Heterobimetallic Complexes, Whitney Kaye Walker

Theses and Dissertations

Conventional ligand design in transition metal catalysis capitalizes on the ability of phosphorous, nitrogen, carbon, oxygen, and sulfur-based donors to modify the steric and electronic properties of a reactive metal center. Heterobimetallic transition metal complexes that contain a dative metal-metal bond provide a unique approach to ligand design where the reactivity of the metal center can be modified by metal-metal electronic communication. Our laboratory is interested in using the unique properties of heterobimetallic complexes to address significant limitations in current transition metal catalysis. My PhD work has focused on the ability of early/late transition metal heterobimetallic complexes to facilitate catalysis …

Development Of Lower Rio Grande River Water Quality Transportation Numerical Model For Bi-National River Management, Jose O. Gonzalez Aug 2017

Development Of Lower Rio Grande River Water Quality Transportation Numerical Model For Bi-National River Management, Jose O. Gonzalez

Theses and Dissertations

Traditionally, water quality modelling has focused on modelling individual water bodies. However, water quality management problems must be analyzed at the larger scale to include influences from various water bodies that are interconnected. This paper provides a study on the hydrologic and quality transportation calculation by developing a hydrodynamic (unsteady state) channel routing model using a water-balanced approach. A one dimension Lagrangian river model was developed and applied to the 210 plus miles for the lower Rio Grande River Basin from the Falcon Dam to the head water of Brownsville that pours onto the Gulf of Mexico. This model can …

This thesis peruses the flow pattern of the orthogonal electrode pattern and circular electrode providing, examples of the flow patterns and the process micromixing. Characteristics of a multifunctional system were demonstrated using orthogonal electrode and circular electrode patterned device. Conductivity of the fluids were chosen such they reflect …


"La Reyna Es El Rey": Expressions Of Gender Identity By Female Mariachis In The Southwest, Erika J. Soveranes Aug 2017

"La Reyna Es El Rey": Expressions Of Gender Identity By Female Mariachis In The Southwest, Erika J. Soveranes

Theses and Dissertations

Since the 1990s, the popularity of all-female mariachis has grown in the United States. These ensembles push the boundaries, both socially and stylistically, of a genre which has traditionally disregarded female participation. In this thesis, I study two all-female mariachi groups in the Southwest in which I have participated: Mariachi Buenaventura from Santa Fe, New Mexico, and Mariachi Margaritas from Brownsville, Texas. These two groups struggle to establish their reputation and aspire towards equal recognition to their male counterparts on the basis of musicality. Based on musical analysis and ethnographic reflections, I argue that the mariachi tradition embodies patriarchal values …


Molecular Dynamics Simulations Of Dna Duplex Stretching, Ramin Salimi Aug 2017

Molecular Dynamics Simulations Of Dna Duplex Stretching, Ramin Salimi

Theses and Dissertations

Single-molecule DNA stretching experiments is a an extremely rigorous method to investigate mechanical properties of DNA and how DNA molecule binding to proteins, and other small molecules works. In these experiments, double-stranded DNA molecules are stretched by a force applied to opposite ends of the DNA, e.g., in an atomic force microscope or an optical tweezers instrument. Here we study the stretching behavior of the DNA duplex d(CGCAAAAAAGCG) 2 by molecular dynamics simulations. In particular, we calculate the change in free energy ∆F = ∆U − T ∆S as the DNA duplex is stretched. We seek to show that employing …


Microwave-Promoted Iminyl Radical Cyclizations For The Synthesis Of Azaheterocycles And The Total Synthesis Of Yaku'amide A, Yu Cai Aug 2017

Microwave-Promoted Iminyl Radical Cyclizations For The Synthesis Of Azaheterocycles And The Total Synthesis Of Yaku'amide A, Yu Cai

Theses and Dissertations

Two different research projects are described in this dissertation. The first one focuses on microwave-promoted iminyl radical cyclization for the formation of azaheterocycles which are embedded within numerous pharmaceuticals and biologically active natural products (such as clindamycin, eletriptan, moxiflaxin, etc.). We are quite interested in this project because of the significance of nitrogen-containing heterocycles as pharmaceuticals and organocatalysts combined with the need for safe, simple, and economical means of constructing them. We have successfully developed an efficient one-step synthesis of 2-acylpyrroles and diastereoselective dihydropyrroles from readily available oxime ether substrates. This remarkably efficient and environmentally friendly methodology should be useful …


Post-Translational Regulation Of Superoxide Dismutase 1 (Sod1): The Effect Of K122 Acylation On Sod1'S Metabolic Activity, Courtney Jean Banks Aug 2017

Post-Translational Regulation Of Superoxide Dismutase 1 (Sod1): The Effect Of K122 Acylation On Sod1'S Metabolic Activity, Courtney Jean Banks

Theses and Dissertations

Many mutations in superoxide dismutase 1 (SOD1) cause destabilization and misfolding of the protein and are implicated in amyotrophic lateral sclerosis. Likewise, a few post-translational modifications (PTMs) on SOD1 have been shown to cause the same phenotype. However, relatively few PTMs on SOD1 have been studied in depth and, in particular, very few studies have demonstrated how these PTMs affect SOD1's various biological roles. SOD1 is traditionally known for its role in reactive oxygen species (ROS)-scavenging but has also been found to have a few other biological roles, including transcription factor activity to promote genomic stability, preservation of cytoskeletal activity, …


Mri T2 Signal Changes Indicate Tau Pathophysiology In A Murine Alzheimer's Disease Model, Rajan Deep Adhikari Aug 2017

Mri T2 Signal Changes Indicate Tau Pathophysiology In A Murine Alzheimer's Disease Model, Rajan Deep Adhikari

Theses and Dissertations

Pathogenesis, diagnosis and treatment, the essential domains in medical practice, seem helpless to address Alzheimer's disease (AD). With a huge mortality rate, it is looming and threatening the socioeconomic barrier. Despite many different studies, the pathogenesis of AD remains inconclusive. However, growing numbers of studies suggest oxidative stress to contribute to the initiation and progression of AD. We propose an iron hypothesis: iron mediated oxidative damage by reactive oxygen species (ROS), which induces protective roles of amyloid beta and hyper-phosphorylated tau (HP-tau) to sequester iron and limit the disease. We propose to study such mechanism using transgenic mice models for …


When To Wed? A Closer Examination Of The Association Between Age Of Marriage And Marital Quality, Kaylee Shron Corbridge Aug 2017

When To Wed? A Closer Examination Of The Association Between Age Of Marriage And Marital Quality, Kaylee Shron Corbridge

Theses and Dissertations

With the rising age of marriage and previous research failing to address a more detailed look at more descriptive measures of satisfaction, the current study examined the association between age of first marriage and marital stability, satisfaction, sexual satisfaction and frequency, effective communication, conflict, and problem areas. Results from a sample of 470 participants who completed the RELATE Questionnaire indicated that across the board, those who married from ages 20-24 had better marital outcomes than those who delayed marriage until their thirties and beyond. These results fit a possible theory of explanation that when it comes to age of marriage, …


Physiological Effects Of Pathogen And Herbivore Risks Encountered By Quaking Aspen, Anson Clark Call Aug 2017

Physiological Effects Of Pathogen And Herbivore Risks Encountered By Quaking Aspen, Anson Clark Call

Theses and Dissertations

Quaking aspen (Populus tremuloides) is the most widely distributed tree in North America (Lindroth and St Clair 2013), and a keystone species in our western montane forests (Worrall et al. 2015). Aspen has become a model organism for studies of genetics and physiology in woody plants (Bradshaw et al. 2000, Taylor 2002). Aspen is also economicallyimportant (Worrall et al. 2015) – wood is harvested for various uses, its scenic beauty helps sustain the tourism economy in many areas, and it has recently been studied as a possible source of biofuel (Sannigrahi et al. 2010). Aspen is also a …

Theses and Dissertations

The present study examined public perceptions of and willingness to provide social support to survivors of sexual assault presenting with posttraumatic stress disorder (PTSD) based on the survivor’s gender (male vs. female), psychotherapy treatment-seeking status (no treatment vs. dropped out after four sessions vs. still in treatment), and participant gender (male vs. female). Participants (n = 178) read one of six vignettes based on a 2 (gender of survivor of sexual assault: male vs. female) X 3 (treatment-seeking status: no treatment vs. dropped out of treatment after four sessions vs. still in treatment) factorial design describing the life circumstances and …


Examining Drinking Motivation, Resiliency, And Alcohol Use Among American Indian And Caucasian College Students, Emily Sargent Aug 2017

Examining Drinking Motivation, Resiliency, And Alcohol Use Among American Indian And Caucasian College Students, Emily Sargent

Theses and Dissertations

While previous research has suggested American Indians (AI) experience higher levels of alcohol use and related consequences than Caucasians (CA), recent research has demonstrated that AI may actually be drinking at the same or lower rates than CA. AI college students may choose to consume alcohol for different reasons than CA students, referred to as drinking motivation. Resiliency (i.e., experiencing positive outcomes regardless of serious threats) may be one factor that moderates the relationship between specific drinking motives and alcohol use. The current study examined alcohol use, drinking motivation, and resiliency among University of North Dakota (UND) AI (n = …


Wayne Booth's Rhetoric Of Pluralism, William John Ordeman Aug 2017

Wayne Booth's Rhetoric Of Pluralism, William John Ordeman

Theses and Dissertations

In this thesis, I will be examining the arguments Wayne C. Booth put forth for Pluralism in rhetorical studies. I will show how Booth believed that ethical criticism, not only in literary criticism but in all disputation, must take place in order for us to understand each other and objective values. Booth believed that our differing opinions and arguments may not be reconcilable, but by employing “listening rhetoric”, a method of paying close attention to the arguments of those who disagree with us, we can arrive at truths that are shared within a community. I juxtapose Booth with both Positivists …


A Being Of Great Order: Reading Lacan In Cormac Mccarthy’S The Crossing, Chamois Summer Holschuh Jul 2017

A Being Of Great Order: Reading Lacan In Cormac Mccarthy’S The Crossing, Chamois Summer Holschuh

Theses and Dissertations

Cormac McCarthy’s The Crossing follows Billy Parham on a psychologically taxing series of adventures that leave the teenaged would-be cowboy in utter despair by the end of the novel. His unhappiness and dissatisfaction invite a Lacanian reading. This thesis first explores his efforts to trap a pregnant shewolf as an illustration of Jacques Lacan’s treatment of das Ding and the role of the objet petit a. While the she wolf functions as an objet petit a in the trajectory of Billy’s desire, la matriz, a scent used by hunters to lure wolves, is used as a conceptual depiction of das …


Sympathy For The Devils: An Analysis Of The Villain Archetype Since The Nineteenth Century, Michel Martin Del Campo Jul 2017

Sympathy For The Devils: An Analysis Of The Villain Archetype Since The Nineteenth Century, Michel Martin Del Campo

Theses and Dissertations

The portrayal of villains has changed dramatically since the late nineteenth century. Modern villains are not necessarily punished, and they are presented as relatable or at the very least sympathetic. An analysis of the major events that shook the Western World in the last century reveals a pattern that links the classical style villain to the modern anti-villain via sociological and cultural changes. The Victorian period showed the West that the British Empire was not eternal and could be threatened. Count Dracula in Bram Stoker’s Dracula represented these fears and forced the Victorians to reexamine everything from their belief in …
