Development Of The K-State (Competence) And Mutagenesis In Stressed Bacillus Subtillis Cells, Amanda Kidman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mutagenesis is central to the evolutionary process. We currently view evolution as a gradual process affecting all cells within a population. However, my project studied an underestimated part of the evolutionary process: mutations generated during stationary phase (caused by nutritional stress or growth arrest) within a subpopulation of cells. I used Bacillus subtilis, a bacterial model for cell growth and differentiation. Stationary-phase cultures of B. subtilis differentiate subpopulations that exhibit different survival strategies including competence, secondary metabolite production, biofilm formation, cannibalism, and endospore formation. The development of competence permits cells to uptake exogenous DNA and incorporate it into their genome. …

An Investigation Of The Testing Effect On Motor Learning, Aaron Leonard Pauls

UNLV Theses, Dissertations, Professional Papers, and Capstones

Optimization of learning processes is the goal many educators strive to achieve with their students. One of the potential methods used towards optimizing this process is what’s known as the testing effect. The testing effect is the improved performance on a retention test as a result of prior testing during some period of practice. Previously, the testing effect was investigated using mostly cognitive tasks such as the learning of a number of words. In this paper, we examine the impact the testing effect has on learning the motor skill of putting. The study used a 2 x 2 mixed design, …

Beal, Michael J. Walsh, Robert R. Bidigare, Susan L. Brown, William P. Cochlan, Zackary I. Johnson, Xin Gen Lei, Stephen C. Machesky, Donald Redalje, Ruth E. Richardson, Viswanath Kiron, Virginia Corless

Faculty Publications

Climate, energy, and food security are three of the greatest challenges society faces this century. Solutions for mitigating the effects of climate change often conflict with solutions for ensuring society’s future energy and food requirements. For example, BioEnergy with Carbon Capture and Storage (BECCS) has been proposed as an important method for achieving negative CO2 emissions later this century while simultaneously producing renewable energy on a global scale. However, BECCS has many negative environmental consequences for land, nutrient, and water use as well as biodiversity and food production. In contrast, large-scale industrial cultivation of marine microalgae can provide society with …

Local And State Governments Are Taking The Stage When It Is Fda's Curtain Call - Are Local And State Governments' Safety Warnings Preempted By Federal Law?, Melissa M. Card

Journal of Food Law & Policy

Eliminated from fad diets, sworn off by celebrities, and frantically reformulated out of processed foods, added sugars have been deemed the new nutritional scoundrel. Recent studies from the American Heart Association, the World Health Organization, and the American Cancer Association demonstrate that the consumption of added sugar leads to increased risks of obesity, diabetes, heart disease, and gout. While all foods containing added sugar are deemed unhealthy, Sugary-Sweetened Beverages ("SSBs") are said to be especially toxic by the American health community, by virtue of these beverages' being excessively high in added sugar content, low in satiety, and incomplete in compensation …

To Boldly Go: Boldness Predicts Behavior And Survivorship Of A Critical Prey Species, Zoe Katherine Tinkle

Boise State University Theses and Dissertations

Understanding population dynamics is at the core of conservation biology. However, our understanding of the mechanisms driving population dynamics remains unclear in many cases. Animal behavior in response to biotic and abiotic stressors is an important driver of these population dynamics and varies both within- and among-individuals in a population. Consistent differences in behavior among individuals within a population are referred to as personality traits. Boldness, a personality trait representing the willingness of an individual to engage in risky behavior, may help predict individual and community-level consequences, such as survivorship. Here, we investigated the inter- and intra-individual variation in risk-taking …

Will Consumers Be In The "Dark" About Labels On Genetically Engineered And Modified Foods?, Hilary Nat

Journal of Food Law & Policy

In the 1900s, the United States began to sell genetically engineered foods. One of the first genetically engineered foods sold in the United States and approved by the Food and Drug Administration (FDA) was the Flavr Savr tomato. The tomato's genetic structure was modified to prevent softening which allowed it to ripen after being picked. In the United States, statistics demonstrate that 92% of com, 94% of soybeans, and 94% of cotton sold is genetically engineered. In addition, it is estimated that 75% of the processed foods sold in supermarkets around the United States contain ingredients that are products of …

The New Radicals: How Wage Labor, Physical Abuse And An Agrarian Crisis Shaped Women's Participation In The Zapatista Rebellion, Patrick E. Brady

Honors Capstones

My experiences in San Cristóbal de las Casas have been the primary motivation for my interest in female Zapatistas. Ever since I concluded my research project, I have had a question that has been largely unanswered by scholars. What are the separate economic and social factors that motivated indigenous Tetzel and Tzotzil men and women to volunteer in the Zapatista Rebellion, and how has feminism influenced indigenous women’s participation in the rebellion? Up to this point, few historians have studied the gendered nature of the causes for indigenous participation in the EZLN. Those who have were concerned with the impact …

Avoiding Linguistic Neglect Of Deaf Children, T. Humphries, P. Kushalnagar, G. Mathur, Donna Jo Napoli, C. Padden, C. Rathmann, S. Smith

Linguistics Faculty Works

Deaf children who are not provided with a sign language early in their development are at risk of linguistic deprivation; they may never be fluent in any language, and they may have deficits in cognitive activities that rely on a firm foundation in a first language. These children are socially and emotionally isolated. Deafness makes a child vulnerable to abuse, and linguistic deprivation compounds the abuse because the child is less able to report it. Parents rely on professionals as guides in making responsible choices in raising and educating their deaf children. But lack of expertise on language acquisition and …

Evaluating The Likelihood Of Use Of Bispectral Index Guided Anesthesia As A Strategy To Reduce Postoperative Delirium In Surgical Patients 65 Years Of Age Or Older, Simon Jack Gibson

Doctoral Projects

Postoperative delirium (POD) is the most common postoperative complication in the elderly, accounting for approximately $164 billion in costs per year in the United States (Inouye, Westendorp, & Saczynski, 2014, p. 911). This complication occurs in as many as 50% of elderly patients, but can be prevented as much as 40% of the time (Inouye et al., 2014). The use of processed encephalographic monitoring, such as Bispectral Index (BIS) monitoring, to guide anesthetic dosage is the single intraoperative intervention with enough evidence to support it as a recommendation for use to reduce POD (American Geriatrics Society, 2015). There were two …

Manipal Journal of Medical Sciences

Human immunodeficiency virus infection (HIV) has become a manageable disease due to antiretroviral therapy. Although many treatment schedules are effective in controlling the viral load, maintaining it for a long period is difficult due to many factors such as adverse effects, long-term toxicity, and dosing schedules, all of them may result in poor patient compliance, treatment failure and drug resistance. The evaluation of these treatment schedules in terms of their efficacy, duration, and acceptance is an important aspect for treating doctors, patients, and policy makers. Therefore, our objective is to evaluate stavudine, lamivudine, and nevirapine regimen in the management of …

Spinal Cord Injury Modulates The Lung Inflammatory Response In Mechanically Ventilated Rats: A Comparative Animal Study, Karine Truflandier, Eric Beaumont, Karim Maghni, Michel De Marchie, Emmanuel Charbonney, Jadranka Spahija

ETSU Faculty Works

Mechanical ventilation (MV) is widely used in spinal injury patients to compensate for respiratory muscle failure. MV is known to induce lung inflammation, while spinal cord injury (SCI) is known to contribute to local inflammatory response. Interaction between MV and SCI was evaluated in order to assess the impact it may have on the pulmonary inflammatory profile. Sprague Dawley rats were anesthetized for 24 h and randomized to receive either MV or not. The MV group included C4–C5 SCI, T10 SCI and uninjured animals. The nonventilated (NV) group included T10 SCI and uninjured animals. Inflammatory cytokine profile, inflammation related to …

Reproductive Ecology Of Greater Sage-Grouse In Strawberry Valley, Utah, Jared Jeffrey Baxter

Theses and Dissertations

Greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) are a species of conservation concern in the rangelands of western North America due to their dramatic decline over the last half century. Effective conservation and management of sensitive species requires an understanding of how species respond to management actions. We examined two aspects of the reproductive phases of sage-grouse: nest predation, and habitat selection by female sage-grouse with chicks. In Chapter 1, we developed resource selection functions to assess the influence of mechanical treatments of mountain big sagebrush (Artemisia tridentata vaseyana) on habitat selection by greater sage-grouse with chicks. …
