Polyomavirus Enhancer Activator 3 (Pea3), A Member Of The Ets Family Of Transcription Factors, Is A Transcriptional Activator Of Notch-1 And Notch-4 In Breast Cancer: An Opportunity For Novel Combinational Therapy, Anthony George Clementz

Dissertations

Women diagnosed with triple-negative breast cancer have the worst overall prognosis and frequently present with metastatic tumors. To date, there are no targeted therapies available to combat this aggressive form of breast cancer due to the lack of expression of well-known targets such as ER-alpha, PR, or HER2/neu. Therefore, there is an immediate need to identify novel targets that are responsible for the proliferation, survival, and invasive phenotype. Notch-1 and Notch-4, both potent breast oncogenes, are overexpressed in triple-negative breast cancers-associated with the poorest overall survival. PEA3 (polyomavirus enhancer activator 3), a member of the Ets family of transcription factors, …

Visitors Pass: The Story Of A Group Of Pakistani Immigrant Students At Sawyer High School, Melissa Gersh Fischer

Dissertations

New immigrant populations are shaped in significant ways by globalization. The phenomenon of transnationalism has changed the localized sense of "home" and "local cultures" on a global scale. In fact, "Globalization lies at the core of current sociocultural experiences, especially in processes of identity construction, communal practices, subject positioning, and agency" (Santiago-Irizarry, 2008). This ethnographic study focuses on the question of how agency and institutional structures, in a global society, impact the lived experiences of Pakistani immigrant students at an urban public high school. A review of literature on identity formation, globalization, and institutional structures is essential to answering this …

In Whose Best Interest? Using An Experimental Vignette To Assess Factors Influencing Placement Decisions In Child Welfare, Jeff Sieracki

Academy Students' And Pre-Service Teachers' Perceptions Of The Use Of Electronic Technology In Their Personal Life And School Experiences In A Selected Union Conference, Alan R. Williams

Dissertations

Problem. The influx of N-Gen students into the classroom of teachers of earlier generations has created a digital generation gap. This gap has serious consequences for schools. For example, only half of the public school teachers who had computers or the Internet available in their schools use them for classroom instruction. However, today’s students are very technology savvy, feel strongly about the positive value of technology and rely upon technology as an essential and preferred component of every aspect of their lives. It appears that the slow speed at which technology is changing the classroom is providing challenges to educators …

A Historical-Contextual Analysis Of The Final-Generation Theology Of M. L. Andreasen, Paul M. Evans

Dissertations

A Land Fit For Heroes?: The Great War, Memory, Popular Culture, And Politics In Ireland Since 1914, Jason Robert Myers

Dissertations

Despite the fact that over 200,000 Irish men fought in the British Army during the First World War, Ireland's sizeable contribution to the war remained in the shadows of history for most of the twentieth century. This dissertation examines the cultural components of the memory of the Great War in Ireland and argues that, taken together, they constitute an alternative Irish national identity that threatened and challenged republican nationalism. These cultural components existed in the realm of vernacular memory, which lay beyond the reach of the Irish government. By examining commemorative rituals, war memorials, and popular culture, this project breathes …

Resurrecting The Past, Constructing The Future: A Historical Investigation On The Formation Of A Greek National Identity In Schools, 1834-1913, Theodore G. Zervas

The timeframe this project examines is significant because it covers an important portion of Modern Greek history. The beginning of the modern state …

Ethanol Impairs Mechanisms Of Macrophage Phagocytosis And Cytokine Production, John Karavitis

Dissertations

Extensive evidence indicates that alcohol (ethanol) consumption affects human health by altering normal physiological functions of the immune system. This study investigated the effect of a single in vivo exposure of macrophages to clinically relevant levels of ethanol (1.2 and 2.2 g/kg). Following 3 hour exposure, both doses of ethanol decreased ex vivo TNFα production by splenic and alveolar macrophages (AMs). Interestingly, the higher dose of ethanol resulted in sustained suppression of LPS-induced TNFα production at 3 and 6 hours post ethanol administration, as well as decreased IL-6 and IL-12 production after 6 hours, compared control treated groups. LPS or …

Characterization Of Tram, A Required Bacteroides Fragilis Conjugal Apparatus Protein That Interacts With The B. Fragilis Putative Coupling Protein Bcta And The B. Fragilis Relaxase Protein Bmph, Mai Thi Thanh Nguyen

Dissertations

Bacteroides spp. organisms, the most prominent bacteria of the human colon, are reservoirs of antibiotic resistance genes which promiscuously transfer within and from the genus via conjugation. The B. fragilis clinical isolate LV23 harbors a 37kb conjugative transposon, BTF-37. Two important conjugal apparatus proteins encoded by BTF-37 are BctA, a predicted coupling protein (CP) that powers DNA translocation, and ORF7 (TraM). In this study, we demonstrated that TraM exhibits characteristics of a required conjugal apparatus protein including 1) upregulated expression under conjugation conditions; 2) localization to the bacterial inner membrane; 3) interaction with the putative coupling protein BctA and the …

Morphogenesis Of The Bacillus Anthracis Spore, Michael Mallozzi

Dissertations

With the ability to shut down metabolism, survive exposure to high degrees of heat, ultra-violet and ionizing radiation, digestive enzymes, and antimicrobials, the bacterial spore is one of the most-resistant forms of life on earth. Although most spores are harmless, several species' spores cause serious diseases such as tetanus, anthrax, gas gangrene, botulism, and diarrhea. Spore-forming bacteria differentiate into spores in response to stresses (especially starvation) in a multi-stage developmental pathway involving the coordinated expression of hundreds of genes and the formation of specialized protective organelles which surround and protect the spore during dormancy. The Bacillus anthracis spore (the causative …

The Impact Of Person-Centered Communications On Political Candidate Evaluation: An Experimental Investigation, Randall A. Renstrom

Dissertations

"Person-centeredness" refers to how empathetic and warm a person's communication style is. Although the role of person-centeredness has been documented in various areas concerning interpersonal relations, person-centeredness has not been explored in the political realm. This project investigated how person-centered communications can influence impressions and evaluations of political candidates. In the first study, person-centered (PC) messages were shown to impact candidate trait ratings. Candidates using low PC messages were associated with more instrumental traits but fewer socio-emotional traits, while high PC candidates were assumed to have more socio-emotional traits but fewer instrumental traits. Similar results were found when participants rated …

The Roles And Responsibilities Of The Principal As Perceived By Illinois K-8 Principals Who Belong To Generation X, Keith Westman

Dissertations

The roles and responsibilities of the school principal have changed throughout the years, and, with that, the face of the principalship has changed, too. The average age of principals in the United States is 57 with a significant portion of those individuals retiring within the next ten years (United States Department of Labor, 2008). As these principals retire, the qualities and characteristics of the next generation of principals must be identified. However, it may not be as easy to fill these vacancies as it once was. Within the context of the research that has been done on Generation X, the …

The 2008 United States Senate Elections: A Typology Of Negative Themes On Candidate-Sponsored Websites, Erin Brining Hammond

Dissertations

The following study is an examination of the negativity on candidate-sponsored websites for the 2008 United States Senate candidates. Results of a content analysis indicated that negative themes identified were more likely to be oppositional than comparative (Johnson-Cartee & Copeland, 1991) and were more likely to be characterbased than policy-based (Benoit, 1999, 2007). The majority of negative themes were identified as focusing on issue stands rather than political record, job experience, criminal activities, religion, marriage/sex life, family members, medical history, or personal life (Johnson-Cartee & Copeland's, 1989).
