The novel SARS-CoV-2 is responsible for causing the ongoing outbreak of coronavirus disease 19 (COVID-19), a systemic infection in humans. Ever since it was first detected in December 2019, the number of confirmed cases has continued to increase. Within a short period, this disease has become a global issue, and therefore it is characterized as a pandemic. The current understanding and explanations are based on epidemiological, clinical and physiological observations. Besides, it remains a great challenge, as much remains to be understood about this new disease-causing virus. Therefore, we seek to provide an overview of SARS-CoV-2, including its classification, origin, …

Development Of A Pediatric Cardiac Assist Maglev Pump For Use With A Universal Driver System., Landon Heath Tompkins

Electronic Theses and Dissertations

Heart failure (HF) remains the leading cause of death, affecting 26 million adults worldwide and 6.5 million adults in the United States. Pediatric HF patients have been a historically underserved population with few options for mechanical circulatory support (MCS) therapy, a leading treatment as an alternative to heart transplantation. To address this clinical need, the Inspired Universal MagLev System is being developed; a low cost, universal magnetically levitated extracorporeal MCS system with interchangeable single-use pumps that will ultimately provide adult and pediatric patients ventricular and respiratory assist therapies. The Inspired Pediatric VAD is the first single-use pump application for this …

Great Expectations: Phosph(On)Ate Prodrugs In Drug Design—Opportunities And Limitations, Victoria Yan

Dissertations and Theses (Open Access)

Phosphate and phosphonates are chemical moieties with historical precedence in anticancer and antiviral nucleotide analogues. Synchronous to modern efforts identifying novel therapeutic targets in cancer, such chemical moieties are being investigated in the design of novel inhibitors with antineoplastic potential. A central challenge to the delivery of phosph(on)ate-containing drugs is their anionic character at physiological pH, which portends poor membrane permeability. This limitation has been successfully overcome through the use of prodrugs. When attached to the phosph(on)ate moiety, prodrugs mask the negative charge and easily enable cell permeability. Upon cellular entry, the promoieties are enzymatically or environmentally cleaved to unveil …

COMBINED INHIBITION OF DDR1 AND CDK4/6 INDUCES SYNERGISTIC EFFECTS IN ER-POSITIVE, HER2-NEGATIVE BREAST CANCER WITH PIK3CA/AKT1 MUTATIONS

Maryam Shariati, M.S. Advisory Professor: Funda Meric-Bernstam, M.D.

Molecular alterations in the phosphatidylinositol 3‑kinase (PI3K)/ serine/threonine protein kinase B (AKT) signaling pathway occur frequently in estrogen receptor–positive (ER-positive) breast tumors. Patients with ER-positive, human epidermal growth factor receptor 2–negative (HER2-negative) metastatic breast cancer are often treated with cyclin-dependent kinase (CDK4/6) inhibitors such as palbociclib in combination with endocrine therapy. Although this is a very effective regimen, disease progression ultimately occurs in most patients. Further, the modulators of palbociclib sensitivity remain unclear. The purpose …

Methods: We conducted a literature search for studies published between December 2019 and May 16, 2020 in PubMed, Embase, and Cochrane (CENTRAL). Descriptive statistics were performed.

Results: We reviewed 14 studies, of …

Effect Of An Intervention To Improve Smoking Cessation Treatment In A Federally Qualified Healthcare Clinic, Shirley A. Camp

The Corinthian

Abstract

Significant progress has been made in the reduction of tobacco use in the United States, but the smoking prevalence among the socially and economically disadvantaged populations (i.e. individuals who are homeless, uninsured, LGBT, and living with HIV) is significantly higher than the general population (CDC, 2018b). As a result, these vulnerable populations carry a disproportionate burden of tobacco-related mortality and morbidity (CDC, 2018b). There is a cost-effective and evidence-based treatment for tobacco use dependence (Fiore et al, 2008), but the delivery by primary care providers to this population is inconsistent (Tyman, Bonevski, Paul, & Bryant, 2014). This study focused …

Deshpande, Raymond B Penn, Stephen B Liggett, Reynold A Panettieri, Xinzhong Dong, Steven S An

Center for Translational Medicine Faculty Papers

The recent discovery of sensory (tastant and odorant) G protein-coupled receptors on the smooth muscle of human bronchi suggests unappreciated therapeutic targets in the management of obstructive lung diseases. Here we have characterized the effects of a wide range of volatile odorants on the contractile state of airway smooth muscle (ASM) and uncovered a complex mechanism of odorant-evoked signaling properties that regulate excitation-contraction (E-C) coupling in human ASM cells. Initial studies established multiple odorous molecules capable of increasing intracellular calcium ([Ca2+]i) in ASM cells, some of which were (paradoxically) associated with ASM relaxation. Subsequent studies showed a terpenoid molecule (nerol)-stimulated …

Simvastatin Induces Unfolded Protein Response And Enhances Temozolomide-Induced Cell Death In Glioblastoma Cells., Sanaz Dastghaib, Shahla Shojaei, Zohreh Mostafavi-Pour, Pawan Sharma, John B Patterson, Afshin Samali, Pooneh Mokarram, Saeid Ghavami

Center for Translational Medicine Faculty Papers

Glioblastoma (GBM) is the most prevalent malignant primary brain tumor with a very poor survival rate. Temozolomide (TMZ) is the common chemotherapeutic agent used for GBM treatment. We recently demonstrated that simvastatin (Simva) increases TMZ-induced apoptosis via the inhibition of autophagic flux in GBM cells. Considering the role of the unfolded protein response (UPR) pathway in the regulation of autophagy, we investigated the involvement of UPR in Simva-TMZ-induced cell death by utilizing highly selective IRE1 RNase activity inhibitor MKC8866, PERK inhibitor GSK-2606414 (PERKi), and eIF2α inhibitor salubrinal. Simva-TMZ treatment decreased the viability of GBM cells and significantly increased apoptotic cell …
