Case Report: Hidden Posterior Dislocation Of The Clavicular Head, David F. Koziel 2024 Jefferson Health NJ

Case Report: Hidden Posterior Dislocation Of The Clavicular Head, David F. Koziel

Rowan-Virtua Research Day

Reported is a case of a 24-year-old male who presented with left shoulder pain and decreased range of motion of the same shoulder upon awakening, diagnosed with a posterior dislocation of the proximal clavicle, with the clavicular head residing in the mediastinum. In the conscious, ambulatory, young adult it is arguably much more common for major bony trauma involving the upper extremity and shoulder to present with pain, deformity, and a known mechanism. This is an example that lacks all three of these characteristics and highlights the importance of details in the physical examination as well as clinical gestalt.


Morel Lavallee Lesion: A Shear Fascia-Nating Soft Tissue Injury, Isaac F. Su, James A. Espinosa, Alan A. Lucerna 2024 Jefferson Health NJ

Morel Lavallee Lesion: A Shear Fascia-Nating Soft Tissue Injury, Isaac F. Su, James A. Espinosa, Alan A. Lucerna

Rowan-Virtua Research Day

Morel-Lavallée lesions (MLLs), first described by their namesake, French physician Victor-Auguste-François Morel-Lavallée, in 1863, represent a distinct category of soft-tissue degloving injuries. These injuries occur when a shearing force disrupts the connection between subcutaneous tissue and fascia, severing lymphatic vessels and capillaries, and leading to an encapsulated collection of lymph, blood, and necrotic fat. Because this space is deep and enclosed, the fluid accumulation cannot easily drain or resolve spontaneously and often an inflammatory capsule develops, further inhibiting resorption. Undiagnosed, patients go on to develop chronic pain, infection, skin necrosis, progressive neurovascular deficits, and, in severe cases, potential loss of …


A Cytoarchitectural Analysis Of The Rat Amygdala In Ultrathin Serial Sections, Katrina Schneider 2024 University of Connecticut

A Cytoarchitectural Analysis Of The Rat Amygdala In Ultrathin Serial Sections, Katrina Schneider

Honors Scholar Theses

This study delves into the cellular composition and functional dynamics of the lateral amygdala (LA), a crucial brain region implicated in emotional and auditory processing/learning. Utilizing IHC, ultrathin serial sectioning (Ultraplex Method), and RNAscope, distinct cell types are characterized within the LA based on calcium-binding proteins (CBPs) and inhibitory markers such as GABA. Despite a modest sample size, a diverse array of cell types are identified, with calbindin-positive neurons prominently emerging in inhibitory cells. Notably, GABA intensity varies depending on cell identity and marker colocalization, hinting at complex regulatory mechanisms involving GABAergic signaling and CBPs. Analysis of vesicular glutamate transporter …

The goal of this project is to determine a way a secure skin grafts to healthy skin in order to reduce …


Wavelet-Based Harmonization Of Local And Global Model Shifts In Federated Learning For Histopathological Images, W. Farzana, A. Temtam, K. M. Iftekharuddin 2024 Old Dominion University

Wavelet-Based Harmonization Of Local And Global Model Shifts In Federated Learning For Histopathological Images, W. Farzana, A. Temtam, K. M. Iftekharuddin

Electrical & Computer Engineering Faculty Publications

Federated Learning (FL) is a promising machine learning approach for development of data-driven global model using collaborative local models across multiple local institutions. However, the heterogeneity of medical imaging data is one of the challenges within FL. This heterogeneity is caused by the variation in imaging scanner protocols across institutions, which may result in weight shift among local models leading to deterioration in predictive accuracy of global model. The prevailing approaches involve applying different FL averaging techniques to enhance the performance of the global model, ignoring the distinct imaging features of the local domain. In this work, we address both …

Pannexin3 In Exercise, Obesity, And Osteoarthritis, Brent Wakefield 2023 Western University

Pannexin3 In Exercise, Obesity, And Osteoarthritis, Brent Wakefield

Electronic Thesis and Dissertation Repository

Pannexin 3 (PANX3), is a glycoprotein that oligomerizes to form mechano-sensitive channels expressed in musculoskeletal tissues, and has been identified as a potential target for the treatment of obesity and osteoarthritis (OA). Obesity and OA are two of the most prevalent diseases worldwide, leading to disability and even death. These conditions are thought to originate from a complex interaction between genetics, aging, sex, and modifiable lifestyle factors, such as exercise. Investigating the interactions between genetic and exercise may provide a more comprehensive, context-specific understanding of gene function. This thesis aimed to understand the interactions between PANX3 and exercise interventions on …

Reversing the pulse polarity, i.e., changing the electric field direction by 180°, inhibits electroporation and electrostimulation by nanosecond electric pulses (nsEPs). This feature, known as “bipolar cancellation,” enables selective remote targeting with nsEPs and reduces the neuromuscular side effects of ablation therapies. We analyzed the biophysical mechanisms and measured how cancellation weakens and is replaced by facilitation when nsEPs are applied from different directions at angles from 0 to 180°. Monolayers of endothelial cells were electroporated by a train of five pulses (600 ns) or five paired pulses (600 + 600 ns) applied at 1 Hz or 833 kHz. Reversing …


The Effect Of Running On The Onset And Development Of Osteoarthritis, Jordan Hekman 2023 Liberty University

The Effect Of Running On The Onset And Development Of Osteoarthritis, Jordan Hekman

Senior Honors Theses

Osteoarthritis is a prominent and debilitating form of joint disease characterized by pain and deterioration of the articular cartilage and other tissues in the affected joint. Research has identified a variety of risk factors for osteoarthritis, including age, obesity, gender, previous injury, and occupation. The relationship between running and osteoarthritis is a topic of particular interest because of the prevalence of running as a simple and physiologically beneficial form of exercise. Increasing evidence suggests that recreational running has at worst no effect and at best a protective effect on joint and articular cartilage health in contrast to high-intensity professional/elite-level running …


Effects Of Diet On Lcn2 Expression And Onset Of Neuroinflammation In An Alzheimer’S Disease Mice Model, Abdirahman A. Hayir 2023 Macalester College

Effects Of Diet On Lcn2 Expression And Onset Of Neuroinflammation In An Alzheimer’S Disease Mice Model, Abdirahman A. Hayir

Neuroscience Honors Projects

This project covers the findings regarding the impact of diet on lipocalin 2 (LCN2) and the effects it has on neuroinflammation Alzheimer’s Disease (AD). LCN2 is a protein that is critical to the functionality of mitochondria and inflammatory responses. Evidence has shown that mitochondrial dysfunction is a potential central event in driving AD pathogenesis and contributing to formation of pathological hallmarks such as chronic inflammation. Furthermore, studies have shown that LCN2 can be deficient under metabolic conditions such as high-fat-diet (HFD). This study investigates if HFD induces LCN2 deficiency and increased neuroinflammation in an AD mice model.
