Amiodarone-Induced Lung Toxicity: An Underrecognized And Fatal Presentation, Andrew Takla, Fahad Eid, Hina Ukrani, Moghniuddin Mohamed, Elizabeth Lee

Advances in Clinical Medical Research and Healthcare Delivery

Amiodarone, a widely utilized antiarrhythmic drug, poses a significant risk of amiodarone-induced lung toxicity (ALT) in up to 10% of patients and can be fatal. This report presents the diagnostic challenges associated with ALT, given its non-specific clinical and radiological presentation. Clinicians should maintain a high index of suspicion for potential ALT, especially in patients with progressive respiratory failure despite optimization of other potential causes such as CHF. The mainstay of treatment is discontinuing amiodarone and initiating steroids. However, outcomes can remain unpredictable, emphasizing the need for heightened awareness and regular monitoring of patients on amiodarone therapy.

Repurposing Clinically Relevant Metabolic Inhibitor Drugs, Difluoromethylornithine (Dfmo) And Orlistat, For Gammaherpesvirus Replication, Lay Paw

Honors Projects

Viruses, including herpesviruses, contribute up to 15% of all human cancers. Murine gammaherpesvirus-68 (MHV-68), a pathogen commonly found in mice, is studied due to its shared homology with several human herpesviruses. Studies done in the Delgado lab via metabolomics analysis show MHV-68 infected cells increase host cell metabolism. Clinically relevant metabolic inhibitor drugs, ɑ-Difluoromethylornithine (DFMO) and Orlistat, respectively block polyamine and lipid production demonstrated a reduction in MHV-68 viral production. Repurposing clinically relevant drugs through the exploration of a different target shows great promise in reducing oncogenic viral titer.

Sdrnas Participate In The Maintenance And Onset Of Prostate Cancer, Neil Chaudhary

Poster Presentations

What is an sdRNA? Noncoding RNA (ncRNA) is a class of RNA that includes microRNA (miRNA) and small nucleolar RNA (snoRNA). Fragments excised from ncRNAs are known as noncodingderived RNA (ndRNA). A certain class of ndRNAs that are derived from snoRNAs have been denoted as Small Nucleolar Derived RNAs (sdRNAs). Our lab has previously hypothesized and demonstrated that sdRNAs display regulatory functions on target genes, similar to the functions of miRNAs. sdRNAs are almost identical to microRNAs and differ mainly in their source of origin.

Our lab has shown that sdRNA-93 is frequently misexpressed in breast cancer cell lines and …

Photon Irradation And Cisplatin Enrich Cancer Stem Cells In Ovarian Cancer, Ashley Antonissen

Electronic Theses, Projects, and Dissertations

High Grade Serous Ovarian Cancer (HGSOC) has a 5-year survival rate of less than 50%. Ovarian cancer is one of the deadliest gynecological diseases and the 7th most common female cancer worldwide. Ovarian cancer patients generally have a poor prognosis despite the relatively successful treatments. When conventional cancer treatments, such as cisplatin chemotherapy and photon irradiation, are administered, residual cancer stem-like cells (CSCs) can survive, leading to CSC enrichment. CSCs are a small population of cancer cells that exhibit stem-like characteristics: quiescence (slowing of the cell cycle), differentiation, proliferation, and self-renewal to regenerate new CSCs. We hypothesized that providing cancer …

Killing Cancer: Manipulating Hydrophobic Vanadium Complexes To Improve Anti-Cancer Activity, Levi Ausherman, Debbie C. Crans, Peter A. Lay, Maggi Braasch-Turi

SACAD: John Heinrichs Scholarly and Creative Activity Days

Hydrophobic vanadium complexes have recently shown improved anti-cancer activities compared to cisplatin. The hydrophobicity and anti-proliferative activity of [VO(Hshed)(dtb)] ([Hshed= N-(salicylideneaminato)-N’-(2-hydroxyethyl)-1,2-ethanediamine and dtb= 3,5-di(tert-butyl)catechol)]) have inspired the development of a library of hydrophobic vanadium complexes. Increasing the steric bulk of the catechol ligand has been shown to have a direct impact on hydrophobicity and anti-proliferative activities. Currently at Fort Hays State University, the Braasch-Turi group is synthesizing VO(HSHED)(dtb) to build up material to support the chemical analysis and biological assay performed by our collaborators at Colorado State University and the University of Sydney, Australia, respectively. In the future, we plan …

Despite the existence of traditional efficacious treatments, a significant number of individuals either do not respond to treatment or experience a recurrence of symptoms over extended periods, spanning 10-12 years. Acceptance and Commitment Therapy (ACT), a form of acceptance-based behavioral therapy considered part of the "third wave" of cognitive behavioral therapies, has shown promising results in early studies, comparable to those of Cognitive Behavioral Therapy (CBT) that is considered the …

Methamphetamine-Induced Dna Double-Stranded Breaks: The Impact Of The Dopamine Transporter And Insights Into The Mechanisms Of Dna Damage In Mouse Neuro 2a Cells, Lizette Couto

Dissertations, Theses, and Capstone Projects

Methamphetamine (METH) abuse remains a global health concern, with emerging evidence highlighting its genotoxic potential. In the central nervous system METH enters dopaminergic cells primarily through the dopamine transporter (DAT), which controls the dynamics of dopamine (DA) neurotransmission by driving the reuptake of extracellular DA into the presynaptic neuronal cell. Additional effects of METH on the storage of DA in synaptic vesicles lead to the dysregulated cytosolic accumulation of DA. Previous studies have shown that after METH disrupts intracellular vesicular stores of DA, the excess DA in the cytosol is rapidly oxidized. This generates an abundance of reactive oxygen species …

Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal

West Chester University Master’s Theses

Proposed regulations for alcohol advertising prevent beverage companies from targeting people under the legal drinking age. However, similar regulations for alcohol alternative beverages are less explored, which could allow alcohol alternative products to create awareness for alcoholic beverages among youth. Alcohol alternatives beverages, including no-alcohol and low-alcohol products, are increasing in popularity and can function as compliments to alcoholic products to decrease the total alcohol volume consumed or as substitutes for alcoholic products. Framing theory can be operationalized through the Content Appealing to Youth Index, an index of content elements found in research literature to be appealing to youth, to …

Examination Of The Time Course Effects Of Electronic Cigarettes On The Thoracic Aorta, Madison Robinson

Graduate Theses, Dissertations, and Problem Reports

Endothelial dysfunction is a critical early marker of the pathogenesis of cardiovascular disease and a pathological biomarker in cigarette smokers. Emerging evidence finds similar cardiovascular risks resulting from electronic cigarettes (E-cig) as that seen from smoking.
