Three Dimensional In Vitro Model Of Head And Neck Squamous Cell Carcinoma, Anna Bulysheva Apr 2012

Three Dimensional In Vitro Model Of Head And Neck Squamous Cell Carcinoma, Anna Bulysheva

Theses and Dissertations

Head and neck squamous cell carcinomas (HNSCC) are among the leading causes of cancer related deaths throughout the world. The survival rate for this type of cancer is extremely low and has not changed significantly in recent decades. There is an imperative need to study tumor progression in a representative model in order to generate more knowledge about this disease as well as develop more effective treatment options. Multiple methods already exist for studying HNSCC and other types of cancers, including in vitro and in vivo models. Although in vivo models are more representative of the human carcinomas in terms …

Sources And Fates Of Nutrients In The Tidal, Freshwater James River, William Isenberg Apr 2012

Sources And Fates Of Nutrients In The Tidal, Freshwater James River, William Isenberg

Theses and Dissertations

Tidal freshwater reaches of estuaries may play an important role in mitigating nutrient fluxes from watersheds to the coastal zone due to their location at the interface between riverine and estuarine systems. We developed annual N and P budgets for the tidal, freshwater James River over 4 calendar years (2007-2010) taking into account riverine inputs at the Fall Line, local points sources (including CSO events), ungagued inputs, riverine outputs, and tidal exchange. The tidal freshwater James River experiences high areal loading rates of TN (383 mg/m2/d) and TP (70 mg/m2/d) due to the combined effects of large watershed area and …

Choosing Surgical Birth: Personal Choice And Medical Jurisdiction, Alexandria Vasquez

Theses and Dissertations

This is an exploratory study of women’s childbearing decisions and outcomes in non-medically indicated cesarean section childbirths (CS). Focusing on the structure-agency dichotomy, the research is guided by Anthony Giddens’ theory of structuration used in the context of the medicalization framework in order to analyze elements of personal choice and medical jurisdiction in childbearing methods. Quantitative analysis of secondary data and a thematic content analysis of Internet forums are conducted in order to analyze women’s perceptions of autonomy and constraint in their childbearing decisions and outcomes. The findings suggest that the polarization between second- and third wave feminist critiques on …

Solvation Of Organic Cations In The Gas Phase And Within Molecular Clusters, Ahmed Hamid Apr 2012

Solvation Of Organic Cations In The Gas Phase And Within Molecular Clusters, Ahmed Hamid

Theses and Dissertations

The role of the solvent in ionic and ion-molecule interactions is of fundamental importance in kinetics and thermodynamics of solution chemistry. However, the study of the ionic interactions in the presence of a large number of solvent molecules is very challenging. Therefore, the gas-phase is the appropriate medium to study such reactions on a molecular level where the ion-solvent interaction can be examined by studying ions surrounded with a cluster of solvent molecules in the complete absence of the any interference caused by the bulk of the solvent. In nature, organic ions can form hydrogen bonds with solvents. An insight …

Poppies And Ptsd: Opioid Influence On A Preclincal Model Of Posttraumatic Stress Disorder., Sarah Vunck Apr 2012

Poppies And Ptsd: Opioid Influence On A Preclincal Model Of Posttraumatic Stress Disorder., Sarah Vunck

Theses and Dissertations

Posttraumatic Stress Disorder (PTSD) is an anxiety disorder that affects over 7.7 million adults and carries an estimated societal cost of $3.1 billion every year. People develop PTSD after exposure to a traumatic event. Alone or combined, approved pharmacotherapies or psychotherapy are somewhat effective, but symptoms for many remain refractory. Emerging evidence suggests that opiate systems may modulate the development and expression of PTSD, and their role can be investigated preclinically. Pavlovian fear conditioning is a preclinical model which elicits behaviors mirroring those that occur in humans during and after exposure to trauma. This presents an experimental tool that can …

Assessing The Effects Of Stress Resilience Training On Visual Discrimination Skills: Implications For Perceptual Resilience In U.S. Warfighters, Andrea Taylor Apr 2012

Assessing The Effects Of Stress Resilience Training On Visual Discrimination Skills: Implications For Perceptual Resilience In U.S. Warfighters, Andrea Taylor

Theses and Dissertations

Current military operational environments are highly improvised and constantly evolving, threatening the lives of U.S. warfighters. For instance, since 2001, 60% of all hostile casualties and 65% of hostile injuries in the Middle East theater have been attributed to improvised explosive devices (IEDs). IEDs are powerful physical weapons, and the stressful atmosphere they, and other operational challenges create, can also result in a range of psychological dysfunctions, including anxiety, depression, alcohol abuse, and Post-Traumatic Stress Disorder (PTSD). Not only are these issues concerning for mental health reasons, they are also problematic in terms of combat performance. Extreme arousal (i.e., stress) …

Opioid Withdrawal Signs And Symptoms In The Pediatric Patient During Opioid Tapering, Deborah Fisher Apr 2012

Opioid Withdrawal Signs And Symptoms In The Pediatric Patient During Opioid Tapering, Deborah Fisher

Theses and Dissertations

Opioids are used routinely in the pediatric intensive care population for analgesia, sedation, blunting of physiologic responses to stress, and safety. In children, physical dependence may occur in as little as two to three days of continuous opioid therapy. Once the child no longer needs the opioid, the medications are reduced over time. A review of the literature revealed that the majority of the published studies used either a neonatal opioid assessment tool or no assessment tool. A subsequent international survey of pediatric providers found a wide range of opioid tapering practices and sporadic use of opioid withdrawal instruments to …

American Beauties: The Cult Of The Bosom In Early Republican Art And Society, Emily Gerhold Apr 2012

American Beauties: The Cult Of The Bosom In Early Republican Art And Society, Emily Gerhold

Theses and Dissertations

This interdisciplinary project offers new research to introduce the American cult of the bosom, which emerged in the years following the Revolutionary War and helped shape the discourse around women’s roles in the early republic. The cult of the bosom sought to shift the way in which the female body, and especially the bosom, was regarded and represented by identifying it as the locus of a number of positive qualities associated with women, including virtue, modesty, beauty, and grace. This shift constituted, in the minds of citizens, a significant way in which American culture honored and celebrated women. Additionally, the …

Myelin Gene Expression: Implications For Alcohol Abuse And Dependence, Sean Farris Mar 2012

Myelin Gene Expression: Implications For Alcohol Abuse And Dependence, Sean Farris

Theses and Dissertations

Acute behavioral responses to ethanol have predictive value for determining an individual's risk of long-term drinking behavior. Although the neurobiology of alcohol abuse is complex, prior studies from our laboratory demonstrated differential myelin-associated gene expression (MAGE) in medial prefrontal cortex (PFC) as one potential mechanism influencing acute ethanol behaviors between C57BL/6J (B6) and DBA/2J (D2) mice. Our laboratory and others have also shown MAGE is reduced in PFC of alcoholics. Herein, I have extended these findings through expression profiling of PFC into chronic models of ethanol self-administration from non-human primates and mice. Together, these results suggest that regulation of MAGE …

A Cellular Automata Model Of Enantiomer Interactions With Beta-Cyclodextrin, Desoi Darren Mar 2012

A Cellular Automata Model Of Enantiomer Interactions With Beta-Cyclodextrin, Desoi Darren

Theses and Dissertations

The binding mechanisms of molecules to cyclodextrins continues to be studied to better explain the interactions occurring. The majority of published models focus on one-to-one molecular binding thermodynamics to explain experimental results. They rely on physical concepts of energies and forces to guide the actions of molecules expressed mathematically in terms of differential and non-linear equations. These models are limited in scope due to their complexity and are not easily expanded to study many diverse analytes. Conversely, cellular automata uses simple mathematical idealizations of systems governed by deterministic and probabilistic rules that are easily adaptable to many types of molecular …

My Identity, Kris Cho Mar 2012

My Identity, Kris Cho

Theses and Dissertations

My identity is the dominate theme in my works. As a Korean American, I am influenced by life experiences in both countries. These two vastly different cultures and experiences define me as an individual. I use references and symbolism from both cultures as elements in my painting, mixed media, and crafts. I have spent half of my life in Korea, my mother country, and the other half in America, my new homeland. Living as an American, my artworks keep me connected to my Korean roots. Creating artwork is my way to relay who I really am as a Korean American.

Prediction Of Respiratory Motion, Suk Jin Lee Mar 2012

Prediction Of Respiratory Motion, Suk Jin Lee

Theses and Dissertations

Radiation therapy is a cancer treatment method that employs high-energy radiation beams to destroy cancer cells by damaging the ability of these cells to reproduce. Thoracic and abdominal tumors may change their positions during respiration by as much as three centimeters during radiation treatment. The prediction of respiratory motion has become an important research area because respiratory motion severely affects precise radiation dose delivery. This study describes recent radiotherapy technologies including tools for measuring target position during radiotherapy and tracking-based delivery systems. In the first part of our study we review three prediction approaches of respiratory motion, i.e., model-based methods, …

Drug Delivery Strategies Using Light Sensitive Molecules, Martin Dcona Mar 2012

Drug Delivery Strategies Using Light Sensitive Molecules, Martin Dcona

Theses and Dissertations

Cancer remains one of the most dreaded diseases due to inevitable suffering and possible fatality. Only cardiac disease has caused more deaths than cancer. Present day cancer treatment involves radiation, surgery or chemotherapy. In chemotherapy, an anti-tumoral drug is used to treat the tumor either by killing or stalling the growth of the tumor cells. In certain types of cancer, for e.g. metastatic breast cancer, the first line of therapy is often chemotherapy. But the inability of current clinically approved drugs to selectively target tumor cells, ultimately results in side effects. To reduce these side effects, prodrug therapies have been …

Adolescent Girls' Experience Of Binge And Loss Of Control Eating, Allison Palmberg Mar 2012

Adolescent Girls' Experience Of Binge And Loss Of Control Eating, Allison Palmberg

Theses and Dissertations

The current investigation used qualitative methodology to examine adolescent girls’ perceptions of control over their eating, as well as triggers, and consequences of binge and related eating behaviors. Focus groups were completed with 19 adolescent girls (aged 13-17, 58% African American, 41% White) who endorsed the behaviors. Responses to focus group questions were qualitatively analyzed using a grounded theory approach and constant comparison coding. Results reflected a fundamental lack of awareness of the loss of control (LOC) eating behaviors. Yet, the data did reflect a central theme of the need to affirm independence and autonomy through eating behaviors via three …

Elevating Endogenous Cannabinoids Reduces Opioid Withdrawal In Mice, Divya Ramesh Feb 2012

Elevating Endogenous Cannabinoids Reduces Opioid Withdrawal In Mice, Divya Ramesh

Theses and Dissertations

Delta9-tetrahydrocannbinol (THC), the primary active constituent of Cannabis sativa, has long been known to reduce opioid withdrawal symptoms. Although THC produces most of its pharmacological actions through the activation of CB1 and CB2 cannabinoid receptors, the role these receptors play in reducing opioid withdrawal symptoms remains unknown. The endogenous cannabinoids, N-arachidonoylethanolamine (anandamide; AEA) and 2-arachidonylglycerol (2-AG), activate both cannabinoid receptors, but are rapidly metabolized by fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL), respectively. The objective of this dissertation was to test whether increasing AEA or 2-AG, via inhibition of their respective hydrolytic enzymes, reduces morphine withdrawal symptoms in …

Blood Glucose Monitoring And Metabolic Control In Youth With Type 1 Diabetes: Relation To Disease Care, Adrienne Borschuk Feb 2012

Blood Glucose Monitoring And Metabolic Control In Youth With Type 1 Diabetes: Relation To Disease Care, Adrienne Borschuk

Theses and Dissertations

Better disease care behaviors in youth with type 1 diabetes (T1D) are strongly related to better metabolic control (HbA1c). However, HbA1c results are only available, on average, every three months, and may not accurately capture intricacies of blood glucose fluctuations. Youth then must rely on blood glucose levels obtained throughout the day to determine which disease care behaviors to perform to maintain optimal metabolic control. Youth may have difficulty performing these disease care behaviors properly or consistently, which makes parental monitoring a crucial aspect of the diabetes regimen. Additionally, youth who experience frequent or severe hypoglycemia may develop a fear …

Comparison Of Steriplex™ Hc And Sodium Hypochlorite Cytotoxicity On Primary Human Gingival Fibroblasts, Jesse Harris Feb 2012

Comparison Of Steriplex™ Hc And Sodium Hypochlorite Cytotoxicity On Primary Human Gingival Fibroblasts, Jesse Harris

Theses and Dissertations

This study examined the cytotoxic effects of STERIPLEX™ HC (sBioMed, Orem, UT) and sodium hypochlorite (NaOCl) on human fibroblast cells in vitro. Fibroblasts exposed to various concentrations of NaOCl or STERIPLEX™ HC were visualized via light microscopy. Dilutions of either NaOCl or STERIPLEX™ HC that did not appear to disrupt the integrity of the cells were recorded for further analysis. Cells were then cultured and grown to confluence in five separate plates. A void was created down the middle of each plate. If the cells were viable, cellular confluence was seen. If nonviable, confluence of the cells did not occur. …

The Antimicrobial Effect Of Steriplex Hc In Comparison With Sodium Hypochlorite On Enterococcus Faecalis, Jonathan Coudron Feb 2012

The Antimicrobial Effect Of Steriplex Hc In Comparison With Sodium Hypochlorite On Enterococcus Faecalis, Jonathan Coudron

Theses and Dissertations

The study objective was to compare the antimicrobial activity of STERIPLEX™ HC with 5.25% sodium hypochlorite (NaOCl) at different dilutions (50%, 25%, 10%, 1%, 0.1%) and different time intervals (1, 3, 5 minutes) on Enterococcus faecalis. All data was analyzed using an ANOVA. The 50%, 25%, and 10% dilutions of both disinfectants reduced the colony forming unit (CFU) count to below the limit of detection (50 CFU/ml) after one minute. The 1% dilutions at each of the time intervals show NaOCl was significantly more effective than STERIPLEX™ HC (all Ps < .0001) in reducing the CFU/ml count. The 0.1% dilutions of NaOCl and STERIPLEX™ HC at 1 minute, were not different (P = 0.7808), while at 3 minutes and 5 minutes NaOCl was significantly more effective (P = 0.0098 and P < .0001, respectively).
