Bicuspid aortic valve (BAV), the most common congenital heart defect, is a major cause of aortic valve disease requiring valve interventions and thoracic aortic aneurysms predisposing to acute aortic dissections. The spectrum of BAV ranges from early onset valve and aortic complications (EBAV) to sporadic late onset disease. Rare genomic copy number variants (CNVs) have previously been implicated in the development of BAV and thoracic aortic aneurysms. We determined the frequency and gene content of rare CNVs in EBAV probands (n = 272) using genome-wide SNP microarray analysis and three complementary CNV detection algorithms (cnvPartition, PennCNV, and QuantiSNP). Unselected control …

Chronic wasting disease (CWD) is a prion disease affecting farmed and free-ranging cervids. CWD is rapidly expanding across North America and its mechanisms of transmission are not completely understood. Considering that cervids are commonly afflicted by nasal bot flies, we tested the potential of these parasites to transmit CWD. Parasites collected from naturally infected white-tailed deer were evaluated for their prion content using the protein misfolding cyclic amplification (PMCA) technology and bioassays. Here, we describe PMCA seeding activity in nasal bot larvae collected from naturally infected, nonclinical deer. These parasites efficiently infect CWD-susceptible mice in ways suggestive of high infectivity …

Harnessing Microrna-Enriched Extracellular Vesicles For Liquid Biopsy, Song Yi Ko, Wonjae Lee, Honami Naora

Faculty, Staff and Student Publications

Extracellular microRNAs (miRNAs) can be detected in body fluids and hold great potential as cancer biomarkers. Extracellular miRNAs are protected from degradation by binding various proteins and through their packaging into extracellular vesicles (EVs). There is evidence that the diagnostic performance of cancer-associated extracellular miRNAs can be improved by assaying EV-miRNA instead of total cell-free miRNA, but several challenges have hampered the advancement of EV-miRNA in liquid biopsy. Because almost all types of cells release EVs, cancer cell-derived EVs might constitute only a minor fraction of EVs in body fluids of cancer patients with low volume disease. Furthermore, a given …

Comparative Effect Of Zoledronic Acid, High Glucose Levels, And Oxidative Stress On Macrophage Viability, Bryan Liu, Denae Cantu, Deborah Seixas, Cláudia Cristina Biguetti

School of Podiatric Medicine - Student Research

Introduction and Hypothesis: Zoledronate (Zol) is an antiosteoclastic drug widely utilized for osteoporosis and bone metastases, and it may be used off-label for managing diabetic Charcot neuroarthropathy1. Since macrophages share common precursors with osteoclasts, their function may also be affected by Zol. Herein, we hypothesize that Zol impairs macrophage responses, potentially hindering their viability and host defense in diabetic conditions.

Methodology: Raw 264.7 macrophages were seeded at 2.5 x 103 in 96-well plates for viability assays. Cells were tested under normal glucose (25 mM), high glucose (ranging from 45 to 70 mM), and high oxidative stress (ranging …

Energy Expenditure In Partial-Foot Amputees With Diabetes: A Scoping Review, Nicholas Obias, Madeleine G. Mehaffey, Amanda Killeen

School of Podiatric Medicine - Student Research

Objective: The energy cost of walking in amputees is often cited in modern scientific literature and clinical rationales for determining amputation levels. However, many referenced papers do not study diabetic populations with partial foot amputations (PFAs) – relatively widespread conditions in podiatric patient populations. Commonly cited papers include Waters (1976), which is significantly dated, Goktepe (2010), which studies traumatic PFAs in a military academy, and Jeans (2011), which studies traumatic PFAs in pediatric populations. These papers do not study diabetic populations and PFAs specifically. We hoped to find a study population more reflective of diabetic patients with PFAs.

Methods: …
