Abstract
Evaluating Outcomes Post-adoption of RECK Solution for Total Shoulder Arthroplasties: A Retrospective Quality Analysis
Benjamin Tillis
Introduction: Local infiltration analgesia (LIA) has become an integral part of postoperative pain relief for West Virginia University (WVU) Medicine’s total joint arthroplasty procedures. However, not all LIAs are the same. Liposomal bupivacaine has a unique mechanism of delivery which could potentially lead to longer lasting effects. Ropivacaine, epinephrine, clonidine, and ketorolac (RECK) solution offers a multimodal approach to enhancing the duration of effect for the LIA. In 2022, WVU Medicine switched from liposomal bupivacaine to the RECK solution for total joint …
Examination Of The Time Course Effects Of Electronic Cigarettes On The Thoracic Aorta, Madison Robinson

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. Logically, the time or length of exposure to E-cigs will likely influence the development of vascular dysfunction, however, the length of exposure that causes permanent damage is unknown. The goal of this study was to determine the potential window of chronic E-cig exposure that results in vascular dysfunction, which is marked by endothelial dysfunction, microvascular dysfunction, and stiffening of arteries. Based on prior chronic …
Spiral Wave Teleportation And Multiplex Network Synchronization In Light Sensitive Belousov-Zhabotinsky Systems, Shannyn Alicia Tyler
Spiral Wave Teleportation And Multiplex Network Synchronization In Light Sensitive Belousov-Zhabotinsky Systems, Shannyn Alicia Tyler
Graduate Theses, Dissertations, and Problem Reports
We experimentally and computationally investigate dynamical behaviors in excitable and oscillatory media using light sensitive Belousov-Zhabotinsky (BZ) systems. These systems are not in a state of thermodynamic equilibrium, and have been proven to show various interesting phenomena including spatiotemporal patterns, self-organization, and chaos. We utilize the BZ reaction, a nonlinear chemical reaction, known for its relaxation-type oscillations, to explore the dynamics of these systems.
We examine spiral wave teleportation in an excitable media as an effective alternate defibrillation method. Spiral waves have emerged as a key phenomenon associated with the initiation and persistence of cardiac arrhythmias. Using a light sensitive …

Cells rely on heat shock proteins (HSP) to facilitate and regulate the folding of the substrate proteins into their native state, and degradation if misfolding cannot be prevented. HSP90, a member of the HSP family, is a potential target for treatment of cancer and neurodegenerative diseases. Unfortunately, several clinical trials for cancer treatment have been discontinued due to cell toxicity accompanying HSP90 inhibition. HSP90 has four distinct but structurally similar paralogs. HSP90 inhibitors target all the paralogs despite increasing proof of functional differences among the paralogs. Understanding the in vivo function of HSP90 and the role played by each paralog …

Oxidative stress is an imbalance between reactive oxygen species production and elimination, favoring the former. Reactive oxygen species serve as important signaling molecules for physiological homeostasis. However, when produced in excess, these once important signaling molecules become detrimental, disrupting cellular functions, and ultimately leading to cell death. In aging, reactive oxygen species production is increased, accompanied with reductions in oxidative stress resistance, increasing the risk for developing age-related diseases including cardiovascular disease, cancer, stroke, and neurodegenerative diseases. The outer mitochondrial membrane iron-sulfur cluster containing protein mitoNEET (CISD1; gene CISD1) has shown to be a mediator of mitochondrial function and …

Multiple myeloma (MM) is a hematological malignancy characterized by the neoplastic proliferation of the plasma cells. MM is a relatively rare cancer that accounts for about 1.8% of all cancers and is the second most common hematologic malignancies, and despite the advancement from untreatable to treatable malignancy, it is yet incurable. Calcium ions (Ca2+) play an important role as second messengers in regulating a plethora of physiological and pathological processes, hence cytoplasmic Ca2+ is tightly regulated with strict spatial and temporal control to initiate, maintain, and terminate appropriate signaling pathways and phenotypes including cellular proliferation, cell cycle …

Perineuronal nets (PNN) are a type of specialized extracellular matrix in the central nervous system. The PNN forms during postnatal development but the ontogeny of the PNN has yet to be elucidated. Studying the PNN in the rat brain may allow us to further understand the PNN’s role in development, learning, and memory. The PNN is fully developed in the deep cerebellar nuclei (DCN) of rats by post-natal day 18. By using enzymatic digestion of the PNN with chondroitinase ABC (ChABC), we studied how digestion of the PNN affects cerebellar-dependent eyeblink conditioning (EBC) and performed electrophysiological recordings from DCN neurons. …

Detection of SCs in body fluids continue to be a challenge because of limited metabolism data, lack of standards and reference mass spectrometry data. In vivo and in vitro experiments help elucidate metabolite markers for novel psychoactive substances and can prompt synthesis of standards to verify proposed metabolites. In this study, metabolism of three SCs N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(5-fluoropentyl)-1H-indole-3-carboxamine (PX-1), N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(5-fluropentyl)-1H-indazole-3-carboxamide (PX-2), and N-(1-amino-1-oxo-3-phenylpropan-2-yl)-1-(cyclohexylmethyl)-1H-indazole-3-carboxamide (PX-3) were investigated using human liver microsomes. Previous studies showed PX-3 as the most potent CB1 and CB2 receptor agonist.
Half-life and clearance data were acquired using liquid chromatography- tandem mass spectrometry. Metabolite elucidation was performed using liquid chromatography …
