Kids Alive! Support For Children Of Parents With Cancer: An Exemplar Program For Children Of Parents With Cancer, Shane Spears

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Cancer in a parent or caregiver is an event that affects the whole family. The roles and responsibilities of the diagnosed parent, as well as those of each family member, are affected at the time of diagnosis and throughout the progression of the illness. According to the American Cancer Society, there will be an estimated 1,665,540 new cancer cases diagnosed and 585,720 cancer deaths in 2014. This staggering statistic means there are a number of cancer diagnoses that will directly affect thousands of parents and their children. Past research suggests this upheaval in the system is particularly stressful on children …

Characterizing The Response Of Multidrug-Resistant Klebsiella Pneumoniae Species To The Application Of A Phage Cocktail, Steven Liu

Symposium

Project Summary: The application of bacteriophages to treat bacterial infections is known as phage therapy, which takes advantage of bacteriophage’s natural ability to infect and lyse bacterial hosts. Phages have been shaped by billions of years of evolution to be highly specialized deliverers of bactericidal agents to the cytoplasm of their target bacteria. Ever since discovery of bacteriophages in 1915, phage therapy was recognized as a potentially powerful tool for eliminating bacterial infections. The effectiveness of phage therapy can be increased by creating a mixture of multiple phages to target a wider variety of bacterial strains. Furthermore, phage therapy has …

Characterization Of Methylene Diphenyl Diisocyanate Protein Conjugates, Morgen Mhike

Dissertations and Theses

Diisocyanates (dNCO) such as methylene diphenyl diisocyanate (MDI) are used primarily as cross-linking agents in the production of polyurethane products such as paints, elastomers, coatings and adhesives, and are the most frequently reported cause of chemically induced immunologic sensitization and occupational asthma (OA). Immune mediated hypersensitivity reactions to dNCOs include allergic rhinitis, asthma, hypersensitivity pneumonitis and allergic contact dermatitis.

There is currently no simple diagnosis for the identification of dNCO asthma due to the variability of symptoms and uncertainty regarding the underlying mechanisms. Immunological sensitization due to dNCO exposure is traditionally thought to require initial conjugation of the dNCO to …

Sphingosine-1-Phosphate Promotes The Differentiation Of Adipose-Derived Stem Cells Into Endothelial Nitric Oxide Synthase (Enos) Expressing Endothelial-Like Cells., Divya Arya, Shaohua Chang, Paul J Dimuzio, Jeffrey Carpenter, Thomas N Tulenko

Department of Surgery Faculty Papers

BACKGROUND: Adipose tissue provides a readily available source of autologous stem cells. Adipose-derived stem cells (ASCs) have been proposed as a source for endothelial cell substitutes for lining the luminal surface of tissue engineered bypass grafts. Endothelial nitric oxide synthase (eNOS) is a key protein in endothelial cell function. Currently, endothelial differentiation from ASCs is limited by poor eNOS expression. The goal of this study was to investigate the role of three molecules, sphingosine-1-phosphate (S1P), bradykinin, and prostaglandin-E1 (PGE1) in ASC endothelial differentiation. Endothelial differentiation markers (CD31, vWF and eNOS) were used to evaluate the level of ASCs differentiation capability. …

Mycobacterium Tuberculosis Central Asian Strain (Cas) Lineage Strains In Pakistan Reveal Lower Diversity Of Miru Loci Than Other Strains, Asho Ali, Zahra Hasan, Sana Jafri, Raunaq Inayat, Rumina Hasan

Department of Pathology and Laboratory Medicine

Mycobacterium tuberculosis (MTB) Central Asian Strain (CAS) lineage strains are predominant in South Asia. Mycobacterial interspersed repetitive units-variable number of tandem repeats (MIRU-VNTR) typing is an effective way of determining genetic diversity of strains. A maximum of 24 loci-based MIRU-VNTR typing can be used, however, it is important to investigate the relevance of specific MIRU loci for regional strains for more cost-effective MIRU typing. MIRU-VNTR typing was performed on MTB strains from Pakistan. Strains were comprised of CAS (n=113) and non-CAS lineages (n=87) - both multi-drug resistant (MDR) and drug susceptible. Hunter Gaston Discriminatory Index (HGDI) for each MIRU loci …

Azd8931, An Equipotent, Reversible Inhibitor Of Signaling By Epidermal Growth Factor Receptor (Egfr), Her2, And Her3: Preclinical Activity In Her2 Non-Amplified Inflammatory Breast Cancer Models., Zhaomei Mu, Teresa Klinowska, Xiaoshen Dong, Emily Foster, Chris Womack, Sandra V Fernandez, Massimo Cristofanilli

Department of Medical Oncology Faculty Papers

INTRODUCTION: Epidermal growth factor receptor (EGFR) overexpression has been associated with prognostic and predictive value in inflammatory breast cancer (IBC). Epidermal growth factor receptor 2 (HER2) overexpression is observed at a higher rate in IBC compared with noninflammatory breast cancer. Current clinically available anti-HER2 therapies are effective only in patients with HER2 amplified breast cancer, including IBC. AZD8931 is a novel small-molecule equipotent inhibitor of EGFR, HER2, and HER3 signaling. In this study, we investigated the antitumor activity of AZD8931 alone or in combination with paclitaxel using preclinical models of EGFR-overexpressed and HER2 non-amplified IBC cells.

The P53-Induced Factor Ei24 Inhibits Nuclear Import Through An Importin Β-Binding-Like Domain., Kim G Lieu, Eun-Hee Shim, Jinling Wang, Ravi K Lokareddy, Tao Tao, Gino Cingolani, Gerard P Zambetti, David A Jans

Department of Biochemistry and Molecular Biology Faculty Papers

The etoposide-induced protein Ei24 was initially identified as a p53-responsive, proapoptotic factor, but no clear function has been described. Here, we use a nonbiased proteomics approach to identify members of the importin (IMP) family of nuclear transporters as interactors of Ei24 and characterize an IMPβ-binding-like (IBBL) domain within Ei24. We show that Ei24 can bind specifically to IMPβ1 and IMPα2, but not other IMPs, and use a mutated IMPβ1 derivative to show that Ei24 binds to the same site on IMPβ1 as the IMPα IBB. Ectopic expression of Ei24 reduced the extent of IMPβ1- or IMPα/β1-dependent nuclear protein import specifically, …

The Role Of Lipocalin 2 In Early Stage Colon Cancer Metastasis To The Liver, Fides Elamparo

Senior Theses

Metastasis, frequently from the colon to the liver, is the major cause of death with colorectal cancer, reducing the five-year survival to less than 6%. Metastasis occurs due to productive collaborations between tumor cells and host-derived cells in the tumor microenvironment, where a pre-metastatic niche is created to prime for cancer cell invasion into the target organ. In a highly metastatic colorectal cancer cell line implanted into the cecum of Balb/c mice, microarray analysis showed lipocalin 2 (Lcn2) is one of the most highly expressed proteins in the liver of tumor-bearing mice prior to metastasis.

When RT-PCR was performed, greater …

A Comparison Of Angiography Versus Intravascular Ultrasound In The Treatment Of Peripheral Arterial Disease, Michael Pompliano

Senior Theses

Peripheral Arterial Disease is a growing epidemic throughout the United States. It is estimated that 8 to 12 million Americans currently suffer from PAD, a disease of the circulatory system that limits blood flow to your hands and feet. This limited blood flow is due to the narrowing of the arteries that supply blood throughout your body and can disrupt the balance of the nerves and tissues that make up your extremities. If left untreated, it can cause irreparable, life- threatening damage that may result in amputation of the diseased limb. Although the mechanism of PAD is known and well …

Influence Of A Palliative Care Protocol On Nurses' Perceived Barriers To Palliative Care And Moral Distress, Christina Cavinder

Evidence-Based Practice Project Reports

The World Health Organization (2013) states palliative care for children should begin at diagnosis which may even occur prenatally. Neonatal palliative care is variable due to the high technological, curative environment in the newborn intensive care unit, and the uncertain prognoses of infants born at the edge of viability. The purpose of this EBP project was to determine the influence of establishing a neonatal palliative care protocol on nurses’ perceived barriers to palliative care and moral distress. Corley’s Moral Distress theory and Stetler’s Model were used as guides for the framework of the project. The protocol, based on guidelines supported …

Cyclic Nucleotide-Dependent Phosphorylation Regulates Bk-Ca Channel Activity In Human Coronary Artery Smooth Muscle Cells, Raeonda Williams

PCOM Biomedical Studies Student Scholarship

Cardiovascular diseases (CVD) can induce dysfunction in organ systems by attenuating normal blood flow. Gonadal steroids are vasoactive hormones, but their role in contributing to cardiovascular function remains controversial. We have demonstrated that gonadal steroids can relax coronary arteries by opening the large-conductance, calcium- and voltage-activated potassium (BKca) channel in smooth muscle cells by increasing cyclic nucleotide levels; however, the signaling pathways involved remain to be elucidated. The purpose of this study was to identify how phosphorylation (via cAMP- and cGMP-dependent protein kinases) I dephosphorylation (via phosphoprotein phosphatase 2A, PP2A) regulates BKca channel activity in human coronary artery smooth muscle …
