Congenital iodide transport defect is an uncommon autosomal recessive disorder caused by loss-of-function variants in the sodium iodide symporter (NIS)-coding SLC5A5 gene and leading to dyshormonogenic congenital hypothyroidism. Here, we conducted a targeted next-generation sequencing assessment of congenital hypothyroidism-causative genes in a cohort of nine unrelated pediatric patients suspected of having a congenital iodide transport defect based on the absence of 99mTc-pertechnetate accumulation in a eutopic thyroid gland. Although, unexpectedly, we could not detect pathogenic SLC5A5 gene variants, we identified two novel compound heterozygous TG gene variants (p.Q29* and c.177-2A>C), three novel heterozygous TG gene variants (p.F1542Vfs*20, p.Y2563C, and …

Quality By Design Based Optimization Of Anti-Inflammatory Nanoemulgels For Local Treatment Of Burn Wounds, Leah Dickey

Electronic Theses and Dissertations

Burns are some of the most traumatizing and damaging skin injuries, with the potential of causing extensive internal damage that increases the risk of chronic wound development. Oral and topical analgesics in combination with antibiotics can provide temporary relief and improve wound healing progress for both mild and severe burns. However, recurrent systemic exposure to pain relievers and antibiotics has been associated with adverse side effects including nausea, drowsiness, abdominal pain, etc., and increased risk of new infections or even ulcers. Local and targeted drug delivery systems, such as nanomedicine, have gained attention as potentially more effective alternatives to improve …

Evaluation Of Medication Optimization In The Setting Of Ecmo Therapy: Assessment Of Therapeutic Effectiveness, Greg Peitz

A series of studies within the setting of extracorporeal membrane oxygenation (ECMO) was undertaken to specifically answer questions related to medication optimization during this complex therapy. These studies included medication therapies involving optimal anticoagulation, analgesia delivery, fluid resuscitation, and infection related outcomes in the context of ECMO. Each investigation was retrospective in nature and included patients from a single institution. The results of these studies indicated the following: 1.) various anticoagulation goals do not impact severe, life-threatening bleeding events during ECMO therapy; 2.) sepsis is a common occurrence in the setting of ECMO; 3.) the choice of either a crystalloid …

The Development And In Vivo Immunologic Assessment Of Biodegradable Microparticles Incorporating Cpdi-02 And Mucosal Protein Vaccine, Jacob E. Parriott

Theses & Dissertations

Encapsulation in biodegradable microparticles (MPs) is a promising approach to increase the efficacy of intranasally administered protein vaccines. The generation of long-lived adaptive immune responses against encapsulated protein vaccines, however, requires the incorporation of a suitable mucosal adjuvant. CPDI-02—a complement peptide-derived immunostimulant that selectively activates dendritic cells and macrophages over neutrophils while minimizing the inflammatory side effects of parent C5a—has previously been incorporated into both systemic and mucosal vaccine formulations via direct conjugation to chemical moieties, peptides, proteins, inactivated pathogens, and the surface of biodegradable particles, to enhance Th1-biased cellular immune responses. The effect of CPDI-02 surface conjugation to MPs …

Breast cancers (BrCas) that overexpress oncogenic tyrosine kinase receptor HER2 are treated with HER2-targeting antibodies (such as trastuzumab) or small-molecule kinase inhibitors (such as lapatinib). However, most patients with metastatic HER2⁺BrCa have intrinsic resistance and nearly all eventually become resistant to HER2-targeting therapy. Resistance to HER2-targeting drugs frequently involves transcriptional reprogramming associated with constitutive activation of different signaling pathways. We have investigated the role of CDK8/19 Mediator kinase, a regulator of transcriptional reprogramming, in the response of HER2⁺BrCa to HER2-targeting drugs. CDK8 was in the top 1% of all genes ranked by correlation with shorter relapse-free …

The COVID-19 pandemic prompted the rapid uptake of Virtual Care (VC). Positive patient outcomes with VC are previously reported but little is known about the experiences of patients and providers using VC during the pandemic. We aimed to describe patient and primary care provider experiences, satisfaction, perceptions, and attitudes to VC during the COVID-19 pandemic that might explain adoption of VC across the continuum of care and inform sustained uptake. We conducted a sequential explanatory mixed methods study using online surveys and virtual interviews with a convenience sample of primary care providers and patients in a Canadian province (July – …

Computational Tools To Expedite The Identification Of Potential Pxr Modulators In Complex Natural Product Mixtures: A Case Study With Five Closely Related Licorice Species, Manal Alhusban, Pankaj Pandey, Jongmin Ahn, Bharathi Avula

Faculty and Student Publications

The genus Glycyrrhiza, comprising approximately 36 spp., possesses complex structural diversity and is documented to possess a wide spectrum of biological activities. Understanding and finding the mechanisms of efficacy or safety for a plant-based therapy is very challenging, yet it is crucial and necessary to understand the polypharmacology of traditional medicines. Licorice extract was shown to modulate the xenobiotic receptors, which might manifest as a potential route for natural product-induced drug interactions. However, different mechanisms could be involved in this phenomenon. Since the induced herb-drug interaction of licorice supplements via Pregnane X receptor (PXR) is understudied, we ventured out to …

We have seen four decades of human struggle to cure or eradicate HIV infection since the first clinical detection of HIV infection. Various developed drugs such as nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors, integrase inhibitors, microbicides, and others have known restrictions, such as side effects and resistance development when used alone, and hidden reservoir of the virus, which have opened the gates for the involvement of nanomedicine associated systems, particularly for latent sites of HIV infection. The nanotechnological vehicles, such as liposomes, dendrimers, metal nanoparticles, polymeric nanocapsules/particles, surfactants, and targeted vehicles have become part …

Indoloquinoline-Mediated Targeted Downregulation Of Kras Through Selective Stabilization Of The Mid-Promoter G-Quadruplex Structure, Alexandra Maria Psaras, Rhianna K. Carty, Jared T. Miller, L. Nathan Tumey

Faculty and Student Publications

KRAS is a well-validated anti-cancer therapeutic target, whose transcriptional downregulation has been demonstrated to be lethal to tumor cells with aberrant KRAS signaling. G-quadruplexes (G4s) are non-canonical nucleic acid structures that mediate central dogmatic events, such as DNA repair, telomere elongation, transcription and splicing events. G4s are attractive drug targets, as they are more globular than B-DNA, enabling more selective gene interactions. Moreover, their genomic prevalence is increased in oncogenic promoters, their formation is increased in human cancers, and they can be modulated with small molecules or targeted nucleic acids. The putative formation of multiple G4s has been described in …
