Isolation And Characterization Of Multipotent Lung Stem Cells From P53 Mutant Mice Models, Venkat Sundar Gadepalli

Theses and Dissertations

Recent advances in understanding lung biology have shown evidence for the existence of resident lung stem cells. Independent studies in identifying and characterizing these somatic lung stem cells have shown the potential role of these cells in lung repair and regeneration. Understanding the functional characteristics of these tissue resident stem/progenitor cells has gained much importance with increasing evidence of cancer stem cells, cells in a tumor tissue with stem cell characteristics. Lung cancer is most commonly characterized by loss of p53 function which results in uncontrolled cell divisions. Incidence of p53 point mutations is highest in lung cancer, with a …

Follow-Up Evaluation Of Treatment For Anxiety And Depression Provided In A University-Based Primary Care Clinic, Renée M. Grinnell

Theses and Dissertations

Although integrated primary care psychology services are becoming increasingly common, the literature lacks adequate research support for the longitudinal durability of treatment effects following the conclusion of brief primary care interventions. This study served as a follow-up program evaluation of psychological services for depression and anxiety provided at the Medical College of Virginia’s Ambulatory Care Center in Richmond, Virginia. Data were collected on 47 adult primary care patients who received treatment for depression and/or anxiety between six and 18 months prior to the follow-up telephone call. Data were collected on the trajectory of depression scores throughout and following treatment, treatment …

Hydropathic Interactions And Protein Structure: Utilizing The Hint Force Field In Structure Prediction And Protein‐Protein Docking., Mostafa H. Ahmed

Theses and Dissertations

Protein structure predication is a field of computational molecular modeling with an enormous potential for improvement. Side-chain geometry prediction is a critical component of this process that is crucial for computational protein structure predication as well as crystallographers in refining experimentally determined protein crystal structures. The cornerstone of side-chain geometry prediction are side-chain rotamer libraries, usually obtained through exhaustive statistical analysis of existing protein structures. Little is known, however, about the driving forces leading to the preference or suitability of one rotamer over another. Construction of 3D hydropathic interaction maps for nearly 30,000 tyrosines extracted from the PDB reveals their …

Examining The Effects Of Human-Animal Interaction On Individuals With Developmental Disabilities, Jennie Feinstein

Theses and Dissertations

Companion animals play a pivotal role in typical human development. It remains unknown how animals affect individuals with developmental disabilities. Based on the knowledge that companion animals help typically developing individuals, this research examined the effects of human-animal interactions on individuals with developmental disabilities.

Human-animal interactions are based on the Biophilia hypothesis, an assertion that an emotional and beneficial relationship exists between humans and nature, in which there is an “innate tendency to focus on life and lifelike processes.” These are the shared, dynamic associations between people and animals, and the effects of those relationships on health and well-being. Sparse …

Novel Therapeutic Strategies For Pancreatic Cancer, Bridget A. Quinn

Theses and Dissertations

Pancreatic cancer is a devastating disease that leaves patients with a very poor prognosis and few therapeutic options. Many of the treatment options available are the same that have been used for almost 2 decades. There is a dire need for both novel treatments for this disease as well as novel strategies of treatment. This body of work will introduce and provide evidence in support of a novel combination therapy for pancreatic cancer treatment, a novel strategy of modifying currently used chemotherapeutics for pancreatic cancer therapy, and a novel transgenic preclinical mouse model of pancreatic cancer. Sabutoclax, an antagonist of …

Mda-9/Syntenin: From Glioblastoma Pathogenesis To Targeted Therapy, Timothy P. Kegelman

Theses and Dissertations

The most common malignant glioma, glioblastoma multiforme (GBM), remains an intractable tumor despite advances in therapy. Its proclivity to infiltrate surrounding brain tissue contributes greatly to its treatment failure and the grim prognosis of patients. Radiation is a staple in modern therapeutic regimens, though cells surviving radiation become more aggressive and invasive. Consequently, it is imperative to define further the cellular mechanisms that control GBM invasion and identify promising novel therapeutic targets. Melanoma differentiation associated gene-9 (MDA-9/Syntenin) is a highly conserved PDZ domain-containing scaffolding protein that promotes invasion and metastasis in human melanoma models. We show that MDA-9/Syntenin is robustly …
