Development Of Anti-Inflammatory Theranostic Nanocolloids Using Quality By Design Approaches, Michele Herneisey

Electronic Theses and Dissertations

Nanocolloids are attractive delivery vehicles for drugs with poor aqueous solubility. Despite this, relatively few nanocolloid products exist on the market. Currently, there is a lack of standardization in the pre-clinical, academic setting regarding nanocolloid development and quality control testing. Adaptation of quality by design (QbD) methods used in the pharmaceutical industry to nanocolloid development is a desirable approach that can improve nanocolloid product and process understanding, resulting in an increased number of marketable products.

The central hypothesis of this work is that QbD approaches can be utilized to optimize theranostic (therapeutic and diagnostic) nanocolloid stability, drug loading, and imaging …

A Bioaffinity Self-Assembling Gel For Localized Delivery Of Immunotherapeutics, Ngoc Pham

Electronic Theses and Dissertations

Renal cell carcinoma (RCC) is a type of cancer in which malignant cells develop in the kidney tubules. Immune checkpoint inhibitors (ICI), including anti-PD-1 antibodies (aPD1), as monotherapies or in combination settings have advanced to the front-line treatment for patients diagnosed with RCC. Systemic infusion of ICI may render subtherapeutic concentrations in the lesions and increase risks of immune-related adverse events. To overcome these limitations, locoregional drug delivery has gained substantial interests as a modality in immuno-oncology. However, conventional intratumoral injections may be ineffective because the high interstitial fluid pressure in tumors resists drug retention and results in rapid local …

Sex-Specific Effects Of Chaperone And Glial Defenses On Experimental Lewy Body Disease, Tarun Bhatia

Electronic Theses and Dissertations

Lewy body disorders are a group of neurodegenerative conditions characterized by the pathological misfolding and aggregation of the abundant protein, α-synuclein. The most common Lewy body disorders are Parkinson’s disease and dementia with Lewy bodies. Apart from ageing, male sex is a major risk factor for Lewy body disorders, as men are at ~1.5-fold higher risk for these diseases than women. Yet, preclinical studies on Lewy body disorders rarely examine sex as a biological variable, and the mechanisms underlying sex-skewedness in disease risk remain undetermined.

Here, we developed a sex-stratified model of Lewy body disorders by exposing primary neurons harvested …

Design And Synthesis Of Fused Pyrimidines As Multi-Targeted Potential Anticancer Agents, Nian Tong

Electronic Theses and Dissertations

Dissertation supervised by Dr. Aleem Gangjee

Targeted cancer chemotherapy represents agents that inhibit cancer cell growth by interfering with specific processes that are required for tumor growth. The crucial aim of the treatment administered to cancer patients should be to improve the quality of life and inhibit the progression of the disease. The current failure of conventional cancer chemotherapy is attributed to both toxicities and the development of resistance. There is an unmet need for new cancer therapies of tumor-targeted agents (that work without harming normal cells or tissues) with a low propensity to develop resistance. Multi-targeted single agents with …

Steps Toward The Total Synthesis Of The Chrysosporazine Family, Katie Kaczynski

Electronic Theses and Dissertations

Cancer is one of the leading causes of death worldwide, with 19.3 million new cancer cases and 10 million deaths in 2020 alone. In the United States, cancer was the second leading cause of death after heart disease. One of the reasons that cancer is so frequently terminal is that cancerous cells frequently develop multidrug resistance (MDR) to frontline chemotherapeutical treatments, resulting in cancers cannot be treated and are inevitably fatal. This makes the discovery of ways to combat MDR so important in the treatment of cancer. The chrysosporazines are a family of recently discovered (2019) natural products that have …

Exploring Moral Permissibility Of Nurse Participation In Limited Resuscitation, Felicia Stokes

Electronic Theses and Dissertations

This dissertation offers a novel approach to support nurses when they face conflict between clinicians and families or alternate decision-makers over potentially inappropriate end-of-life goals of care. This dissertation will provide a normative analysis of the moral permissibility of limited resuscitation, with arguments supported by analyses of families’ and nurses’ perspectives and actions in the EoL decision-making process. Limited resuscitation is a cardiopulmonary resuscitation effort where full pharmacologic and mechanical intervention is not used, or the length of the resuscitative effort is shortened. It is typically associated with deception because it is performed without the knowledge of patients and families. …
