Tobacco/Hiv-1-Induced Myeloid Cell-Derived Extracellular Vesicles In Hiv-1 Pathogenesis, Sanjana Haque

Theses and Dissertations (ETD)

Introduction. Smoking, which is highly prevalent in people living with HIV/AIDS, has been shown to exacerbate HIV-1 replication, in part via cytochrome P450 (CYP)-induced oxidative stress. CYP enzymes metabolize cigarette smoke condensate (CSC), causing oxidative stress and cytotoxicity. Our previous studies have demonstrated that CSC and specific CSC constituents, benzo(a)pyrene and nicotine, potentially induce CYPs, resulting in higher oxidative stress and subsequent exacerbation of HIV-1 replication in monocytes and macrophages. However, the exact mechanism behind tobacco-induced, oxidative stress-mediated enhancement of HIV-1 replication is still poorly understood. Extracellular vesicles (EVs) have recently gained attention for their unique nature as intercellular messengers …

Correlating The Physicochemical Properties Of Magnesium Stearate With Tablet Dissolution And Lubrication, Julie L. Calahan

Theses and Dissertations--Pharmacy

Magnesium stearate (MgSt) is the most commonly used pharmaceutical excipient and is present in over half the tablet formulations on the market. In spite of its popularity as an effective lubricant, it has been repeatedly recognized that there is significant variability between MgSt samples, which can cause inconsistent lubrication between batches of MgSt. The hypothesis of this research is that the batch-to-batch variability in tablet lubrication and dissolution observed in tablet formulations containing different MgSt samples can be correlated with differences in MgSt physicochemical properties (fatty acid salt composition, crystal hydrate form, particle size and surface area). Developing correlations between …

Novel Small Molecule Antifungals For Invasive Fungal Infections, Emily Dennis

Theses and Dissertations--Pharmacy

Human fungal pathogens cause a range of diseases from benign skin conditions (i.e., ringworm) to thrush, mucosal membrane infections, and life-threatening systemic infections including bloodstream infections (i.e., aspergillosis and candidiasis) and Cryptococcal meningitis. These systemic infections occur most often in immunocompromised individuals and have high mortality rates. Current antifungal agents used in the clinic belong to three main classes: the polyenes (e.g., amphotericin B (AmB)), the echinocandins (e.g., caspofungin (CFG)), and the azoles (e.g., fluconazole (FLC)). In addition, the antimetabolite pyrimidine analogue flucytosine is used in combination with AmB. The …

Vaccine Hesitancy: Experimentalism As Regulatory Opportunity, Ana Santos Rutschman, Timothy L. Wiemken

All Faculty Scholarship

This symposium on patient innovation has prompted us to explore problems related to departures from official vaccination schedules. At a time in which vaccine confidence has been plummeting across the world, we argue that a more granular understanding—and ultimately a more finely tuned regulatory framework—is needed to reflect the current behavioral heterogeneity among indicated patients who choose to forego or delay administration of recommended vaccines. In particular, we focus on a phenomenon we term “vaccine staggering:” a departure from vaccination schedules in the form of delays in receiving one or more vaccines, which is motivated by the desire to boost …

Development Of Dexamethsone Sodium Phosphate Loaded Nanoparticles For Treating Corneal Allograft Rejection, Vineet R. Kulkarni

Theses and Dissertations

Corneas are the most commonly transplanted tissue worldwide, with approximately 80,000 transplantations performed in the United States in 2018 alone. Corneal transplantation is used to restore the vision due to opaque corneas in various diseases such as fungal keratitis, keratoconus, Fuchs’s dystrophy, corneal ulceration, traumatic injury, abrasions or scarring, inflammation, and infection. Corneal transplant surgery could involve replacing the entire cornea (penetrating keratoplasty) or selective replacement of the corneal layers (e.g. Descemet’s membrane endothelial keratoplasty and deep anterior lamellar keratoplasty). Immunologic graft rejection is one of the main causes of graft failure in these corneal transplantations. The 2-year rejection rate …

3-D Homology Modeling Of Organic Anion Transporters (Oats): Defining The Biochemical Basis For Oat-Substrate Interactions, Christopher Jay

Theses and Dissertations

A goal in the drug development process, as indicated by the FDA, is to evaluate a drug’s ADME profile, as potential drug interactions could exist, leading to adverse drug reactions or loss of efficacy. Transport proteins, specifically organic anion transporters (OATs) are involved in the absorption, distribution, and elimination of small, negatively charged compounds. Although there is an exhaustive list of structurally diverse organic anions which interact with OATs, interactions at a molecular level are still shrouded in mystery particularly due to the lack of a solved crystal structure. Therefore, in silico homology models (hOAT1, 2, 3) were generated using …
