The Waiting House, Erika Marie Mueller

Theses and Dissertations

The poems in this collection, The Waiting House, use techniques associated with an evolving elegiac tradition in their portrayal of anticipatory grief born of terminal illness and impending loss. Like the melancholic mourning of modern elegies described by Jahan Ramazani, my poems often resist consolation even as they borrow from elegiac conventions like poetic substitution and repetition. Additionally, they utilize strategies and patterns of literary anger outlined by Alicia Suskin Ostriker as common in postwar American women’s poetry, to express anger that is also anticipatory grief. Finally, this collection uses illness metaphors to question the well being of a larger …

The Role Of Viral Interleukin-6 In Tumor Development Of Kaposi's Sarcoma-Associated Herpesvirus Lymphomas, Rebecca A. Fullwood

Theses and Dissertations

Kaposi's sarcoma herpesvirus (KSHV) is a cancer-causing virus, primarily affecting AIDS patients. KSHV is found in 3-10% of the U.S. population and can cause a range of cancers in the highly immunosuppressed; these cancers include Kaposi's sarcoma, pleural effusion lymphoma (PEL) and multicentric Castleman's disease (MCD). The current techniques for treating these cancers are relatively ineffective, largely due to their inefficiency at targeting tumors formed by the infection. One protein produced by KSHV, the viral homolog of interleukin-6 (vIL-6), is thought to play a major role in tumor development post-infection. Here a novel animal model is implemented to study the …

Re-Contacting Cancer Genetic Counseling Patients: Expectations Of Patients And Physicians, Zoe Elizabeth Siegel

Theses and Dissertations

The landscape of cancer genetic counseling and testing is rapidly evolving. Genetic testing technology is improving, management guidelines are evolving, and genetic testing options are expanding. These frequent updates to the components of cancer genetics have increased the complexity of managing patient care over time. In particular, this raises questions on the duty to re-contact patients as new information becomes available. This study explored healthcare providers’ duty to re-contact through the interests and expectations of patients, including which circumstances warrant re-contacting, which healthcare provider is responsible for re-contacting the patient, and the preferred method of re-contacting. Physicians’ opinions on whether …

In Silico Identification And In Vitro Assessment Of A Potential Anticancer Peptide Sequence Retrieved From The Red Sea Metagenomics Library, Mona Elradi Imam

Theses and Dissertations

Cancer is imposing a worldwide health concern with alarming morbidity and mortality rates. Its burden stems from its increasing incidence along with depletion of efficient therapeutic options. Current conventional anticancer therapies; surgery, radiotherapy and chemotherapy are barely effective with deleterious side effects that ruin patients' quality of life. There is a paradigm shift in the interest of pharmaceutical industry towards a new class of peptide based drugs offering more selectivity, easier synthesis, wider safety profile and lower cost of manufacture. Anticancer peptides (ACPs) have gained interest in the last few decades due to their intrinsic properties such as cationicity and …

Cdk8 And Cdk19 As Novel Regulators Of Bmp4 Induced Emt In Cancer, Anne Elizabeth Serrao

Theses and Dissertations

Bone morphogenetic protein 2/4 (BMP2/4), members of the transforming growth factor β (Tgf-β) superfamily, play a dichotomous role in the progression of cancers through cell growth suppression and the enhancement of tumorigenesis in a variety of cancers. Cyclin dependent kinase 8 (CDK8), a protein kinase that regulates gene transcription, is involved in a variety of cancers including breast and pancreatic cancers as well as in mediating BMP2 signaling via its canonical Smad1 pathway. Our studies show that BMP4 induced EMT signals primarily though Smad1 and that Yap1, a transcriptional co-activator, is necessary for BMP4 induced EMT. Using a highly specific …

Investigating The Effects Of Nucleosome Remodeling Factor Knockdown On Anti-Tumor Immunity, Mark G. Roberts

Theses and Dissertations

The nucleosome remodeling factor (NURF) is a chromatin remodeling complex involved in early animal development and is implicated in a number of cancers. In previous work, knockdown of NURF’s largest subunit, BPTF, resulted in diminished tumor growth in mouse cancer cell lines. Other studies in our lab demonstrated increased activation of T-lymphocytes into BPTF KD tumors. In order to examine if this approach has any therapeutic potential, this work investigates the effects of BPTF knockdown in established tumors by using recombinant adenoviruses (rAd), as well as observe the way the immune system interacts with BPTF knockdown cells, both in vivo …

Testing A Low-Intensity And Accessible Cognitive Behavioral Therapy For Insomnia (Cbt-I) Intervention In Individuals Newly Diagnosed With Cancer, Amma Agyemang

Theses and Dissertations

Insomnia is defined as difficulty initiating or maintaining sleep, or nonrestorative sleep that lasts for at least one month and is accompanied by significant impairment in daytime functioning including fatigue, irritability, and/or difficulty concentrating. It is one of the most common complaints reported by individuals with cancer, especially around the time of cancer diagnosis and treatment. Yet it is often unrecognized and untreated, leading to adverse health consequences and increased healthcare costs. Cognitive Behavioral Therapy for Insomnia (CBT-I) has been recommended as the gold standard for treating insomnia among individuals with cancer. Multiple studies have tested and proven the efficacy …

Multifunctional Nanocarriers For Cancer Therapy, Bei Cheng

Theses and Dissertations

Cancer is one of the leading causes of human mortality and mortality in all diseases. There has been a boost in developing nanocarrier-based therapies for treating cancer or other diseases during the past decade. One of the major advantages about nanocarrier (with the size range from 1-1000 nm) lies in its ability to specifically target tumor and maximize drug accumulation in tumor foci through the enhanced permeability and retention effect. Advancement in nanotechnology has opened a new paradigm in pharmaceutical field. But new challenges have to be overcome in order to fully exploit the technology and improve safety in clinical …

Stimuli Responsive Nanoparticle For Cancer Targeted Therapy, Huacheng He

Theses and Dissertations

Nanoparticle is the particle with a size in the range from several nanometers to hundreds of nanometers. It has been extensively used for cancer diagnosis and therapy. However, it is still a great challenge to fabricate nanoparticles with spatiotemporally controllable delivery of anticancer drugs to tumors and with high therapeutic efficacy. This thesis mainly focuses on the development of stimuli responsive nanoparticles for cancer targeted therapy. These nanoparticles either response to internal stimuli such as pH and redox potential or external stimuli like temperature and light could effectively target tumors and control the release of anticancer drugs there to improve …

Momentum Clinic For Teen And Young Adult Cancer Patients, Merian O'Neil

Theses and Dissertations

This study explores the needs of teen and young adult cancer patients undergoing long-term chemotherapy treatments and the design of an outpatient clinic that accommodates this population’s unique needs. Most teens endure long-term treatments in a pediatric facility targeted primarily for children, while others are treated in adult facilities. Teens have different privacy and social needs than children, and while they are not adults, they are involved in their own treatment decisions, unlike children. The target age group for this study is teens and young adults, ages thirteen to twenty-two. A common theme emerged from research and interviews conducted in …

Modeling Spatially Varying Effects Of Chemical Mixtures, Jenna Czarnota

Theses and Dissertations

Cancer incidence is associated with exposures to multiple environmental chemicals, and geographic variation in cancer rates suggests the importance of accommodating spatially varying effects in the analysis of environmental chemical mixtures and disease risk. Traditional regression methods are challenged by the complex correlation patterns inherent among co-occurring chemicals, and the applicability of geographically weighted regression models is limited in the setting of environmental chemical risk analysis. In comparison to traditional methods, weighted quantile sum (WQS) regression performs well in the identification of important environmental exposures, but is limited by the assumption that effects are fixed over space. We present an …
