Nitric Oxide Synthesis By Chicken Macrophages Results In Coordinated Changes Of Multiple Arginine Transporters, Michael Moulds

Master's Theses

Arginine transport is primarily mediated by the cationic amino acid transporters (CATs) in mammalian cells, but in aves the y⁺, b^0,+ and B^0,+ transport systems have also been observed. Arginine is the limiting catabolic substrate required for the production of nitric oxide (NO), a highly reactive compound that acts as a signaling molecule or killing compound. NO is synthesized by inducible nitric oxide synthase (iNOS) by macrophages for pathogen clearance. In mammals, CAT-2B is responsible for ARG import in the macrophage for NO synthesis, but the chicken CAT-2B isoform does not transport ARG. Therefore the objective …

'Better Make It A Double': Perceived Relatedness Increases Reported Attractiveness, Benjamin R. Ainley

Master's Theses

Sexual selection shaped psychological mechanisms in both sexes to assess potential mates for evidence of mate quality (Buss, 2005). Attraction preferences are one such mechanism (Sugiyama, 2005) and physical attraction preferences are sensitive to fitness-promoting traits present in a potential mate. Physically attractive traits are thought to act as signals of good genetic quality (Neff & Pitcher, 2005) and are preferred because of the advantage such quality bestows towards reproductive success. Specifically, genetic quality is proposed to be a biological requirement necessary for physically attractive traits to develop and be maintained (Johnstone & Grafen, 1993). Furthermore, genetic quality is heritable …

The Highest Good And The Best Activity: Aristotle On The Well-Lived Life, Philip William Bauchan

Master's Theses

The question of how Aristotle characterizes eudaimonia, or living-well, in the Nicomachean Ethics has long been a contentious issue amongst Aristotelian scholars. The secondary literature has been roughly divided between inclusivist readers, who argue that Aristotle designates both theoria, or contemplation, and the practical virtues, and exclusivist readers, who argue that Aristotle singles out theoria alone. This thesis seeks to forge a middle ground between these two perspectives by focusing on the central claim of Book I that the eudaimonia is virtuous activity. Reading Book X in light of Book I's claim then allows one to show that both the …

Differences In Eubacterial And Archaeal Soil Communities Along A Precipitation Transect In The Mojave Desert, Elaine Pressly Bryant

Master's Theses

Deserts occupy one third of the total land mass of Earth, yet little is known about microbial soil communities under conditions of low precipitation and humidity. The Mojave Desert of the Southwestern United States provides an opportunity to observe microbial communities along a precipitation transect. The diversity of these communities can elucidate which specific groups of Eubacteria and Archaea are best adapted to limited liquid water.

Two methods were utilized to determine patterns and trends of the microbial soil communities under varying precipitation levels. Viable plate counts allowed comparison of culturable microorganisms over a four-year period. Molecular techniques distinguished unculturable …

Supplemental Home-Based Exercise During Cardiac Rehabilitation, Addison Pica

Master's Theses

In this study, the effects of supplemental, home-based walking on resting systolic blood pressure, waist circumference, and quality of life (QoL) in cardiac rehabilitation (CR) patients were evaluated. Twelve patients wore pedometers during the last four weeks of their 12-week CR program. Resting systolic blood pressure, waist circumference, and QoL were measured at weeks 1, 8, and 12. After data collection, participants were categorized into low, moderate, and high volume groups based on their average number of steps taken per week. There was significant improvement in QoL during the 12-week CR program (F(2,9) = 10.940, p < .001). Participants rated their QoL better at weeks 8 (p = .02) and 12 (p < .001) than at week 1. However, the amount of supplemental walking during the final four weeks of the CR program did not affect QoL scores (F(2,9) =.165, p > .05). Although there were …

An original reflection assignment was introduced into the preclinical curriculum of first year dental students to journal about the legitimacy of their prejudicial beliefs. Results indicated dental students identified a range of prejudicial beliefs and, through self-direction, experienced awareness and …

The Uses Of Expertise: Science, Medicine And Body/Self-Fashioning, Amanda J. Counts

Master's Theses

This paper draws on empirical evidence collected from pro-anorexia websites and qualitative interviews with dieters to develop an analysis of the uses of medical and scientific expertise in processes of body- and self-fashioning. It builds on previous work by examining how `lay publics' refashion expertise in order to use it for new purposes, sometimes contradictory to the purposes of medicine itself. Four distinct groups are analyzed: Women diagnosed with anorexia; women diagnosed with EDNOS (Eating Disorder Not Otherwise Specified); dieters using traditional methods of caloric restricting; and dieters using a new method called Primal Dieting. Overall, respondents indicated an ambivalence …

The Decentralization And Centralization Of Curriculum In The Primary Education Of Burkina Faso, Simon A. Ziba

Master's Theses

In Burkina Faso, a decree which transfers competences and resources related to basic education to municipalities, does not mention the case of curriculum. This study seeks to understand how do educational policymakers in Burkina Faso explain why educational decentralization initiatives have not heretofore affected curriculum issues, and how do they view the possibility and desirability of a decentralized curriculum. It uses qualitative and quantitative methods. This nationwide study has participants who are primary education bureaucrats and educational policymakers at the central, regional and provincial levels of the ministry in charge of basic education. The results of this study show that …

Exercise training, as a rehabilitative strategy, may be a vital factor in combatting the noxious toxicities related to cancer treatment. Research employing mixed modality exercise consistently demonstrates health benefits ranging from enhanced aerobic capacity and muscular strength to attenuated psychological distress. The primary aim of this case study was to examine the effects of exercise training on physiological and psychological parameters in an endometrial cancer survivor undergoing high-dose chemotherapy. Secondly, believed to play a role in toxicity development and progression, oxidative stress has yet to be studied in cancer survivors. The second aim of this case study was to determine …

Expression Of The Artemisia Annua Β-Caryophyllene Synthase In Synechocystis Sp. Strain Pcc6803 Results In Cyanobacterial Sesquiterpene Accumulation, Robert Eric Reinsvold

Master's Theses

The sesquiterpene β-caryophyllene is a ubiquitous component of many plant resins and has been used in the cosmetic industry to provide a woody, spicy aroma. Recent clinical studies have shown its potential effectiveness as an antibiotic, anesthetic, and anti-inflammatory agent. Additionally, there is significant interest in sesquiterpene accumulation in phototrophic microorganisms for the production of biofuels. Currently, the isolation of β-caryophyllene relies on purification methods from oleoresins extracted from large amounts of plant material. The design of a cyanobacterium platform that produces β-caryophyllene may provide a more sustainable and controllable means of production, allowing for an increase in yield without …

An Investigation Into The Use Of Color As A Device To Convey Memes During The Little Ice Age, Peter Allen White

Master's Theses

Color is used as a tool in visual communication to express ideas in a symbolic fashion. It can also be used as a guide to assist the viewer in the visual narrative. Artwork created in the period of time between 1300 to 1850 in northern and central Europe provides a comprehensive perspective in the use of color as symbol and color as an elucidative devise. This period of time is known as the Little Ice Age, the duration of which spans European history between the Medieval period and the Romantic era. The extreme climatic conditions of this era caused profound …

Utility Of Feeding Priority As A Measure Of Dominance In Garnett's Bushbaby (Otolemur Garnettii), Kyle Daniel Edens

Master's Theses

The current study examined dominance behaviors in bushbabies and examined whether feeding priority (i.e., first access to a food source) is a viable measure of dominance. Several measures of dominance were employed. Among the measures of dominance investigated were agonistic interactions, grooming, displacement, and deference of space. The results indicated that females initiated more agonistic interactions than males, but the other measures of dominance did not support the hypothesis that females were the dominant sex. The results were partially consistent with the hypothesis that feeding priority is a viable measure of dominance in that females obtained feeding priority in the …

Emerging research shows a clear relationship between urban design and public health. Major issues effecting public health include cardiovascular disease, high rates of obesity, and associated diseases like Type 2 diabetes. These conditions can be attributed, in a large part, to personal habits, including diet and physical activity. Certain elements of urban design have an impact on personal habits and therefore affect health. This report explores the relationship between urban design and public health, first broadly, and then at a micro-scale, examining the relationship in the context of the City of Delano, California.

This exploratory study begins with an in-depth …

No-Till Vegetable Production At The Cal Poly Organic Farm, Nathaniel Jay Harkleroad

Master's Theses

Tillage and subsequent bare soil have been linked to erosion, nutrient leaching, reduced biological diversity, loss of organic matter, and release of CO2 into the atmosphere (Brady and Weil, 2004). The usefulness of an organic no-till system for transplanted vegetables was explored over two growing seasons. In 2007-2008, in a randomized complete block design, treatments of tilled and no-till (T and NT, respectively) were seeded to a dense grain and legume winter cover crop. Tilled plots were mown and disk-ploughed two times; NT plots retained a mow-killed mulch on the soil surface. There were less weeds in NT plots. A …

The Development And Validation Of A Finite Element Model Of A Canine Rib For Use With A Bone Remodeling Algorithm., Scott J. Sylliaasen

Master's Theses

Studies are currently being performed to determine the effects of bisphosphonate treatments on the structure and density of bone tissue. One of the pathways for gaining a better understanding of the effects of this and other treatments involves creating a computer simulation. Theory suggests that bone tissue structure and density are directly related to the manner in which the tissue is loaded. Remodeling is the process in which bone tissue is resorbed in areas of low stress distributions, and generated in areas of high stress distributions. Previous studies have utilized numerical methods and finite element methods to predict bone structure …

Dentoskeletal And Soft Tissue Treatment Effects Of Two Different Methods For Treating Class Ii Malocclusions., Madhur Upadhyay

Master's Theses

Objectives: Moderate to severe Class II malocclusions can not only cause esthetic and functional problems but can also lead to psychological problems of varying intensity depending on the amount of anterior-posterior discrepancy and its interaction with the related soft tissue structures. Although there are several methods of treating such malocclusions (extractions,distalization,functional appliances etc), the final goal is always to provide acceptable esthetics and stability. The purpose of this clinical-cephalometric study was to examine the dentoskeletal and soft tissue treatment effects of maxillary anterior teeth retraction with mini-implant (MI) anchorage in young adults having Class II Division I malocclusion undergoing extraction …

Meiotic Insurance: Designing A System To Study Crossover Control In Yeast, Kate V. Karfilis

Master's Theses

Meiosis is a specialized form of cell division in which haploid gametes are produced from diploid progenitors. This reduction in ploidy results from proper meiotic chromosome segregation and is ensured by crossover recombination events. Given their importance, it is no surprise that crossover formation is regulated in most eukaryotes. Crossover assurance is a regulatory mechanism that helps to ensure that each pair of chromosomes gets at least one crossover during meiosis.

We seek to better understand how crossover assurance works. To do so, we have developed a system in which crossover formation between a pair of chromosomes is restricted to …

The Effects Of A High-Intensity Resistance Training Program On Muscular Strength, Muscular Endurance, And Psychological Measures In Cancer Survivors, Jessica M. Weiderspon

Master's Theses

Cancer can be characterized as an uncontrolled growth and spread of irregular cells in the body. Approximately 559,880 Americans die from cancer every year, however an estimated 562,340 Americans are anticipated to survive from cancer. With greater advances in treatment and increased survival rates, rehabilitation of normal life functioning becomes a large priority for cancer survivors. It has been found that exercise improves physiological and psychological factors in cancer survivors, although the most advantageous mode, duration, or intensity has not been determined. Aerobic and mixed interventions (aerobic, resistance, flexibility) have been studied in depth but a pure resistance training program …
