3d Modeling Of Brain Removal With Cranial Nerve Preservation, Lauren Blank, Sophia Cox, Avery Preston

Student Scholar Symposium

3D Modeling of Brain Removal with Cranial Nerve Preservation Abstract: Visual- spatial skills are essential in learning anatomy as they allow students to mentally visualize and manipulate the three-dimensional structure of the human body. Traditional dissectors like Grant’s Dissector typically provide only 2D images to guide brain removal. These manuals often do not include the occipital wedge approach, which favors cranial nerve preservation during brain dissection. A 3D model that assists students in learning a non-traditional dissection approach through manipulating a brain model will help improve mental rotation skills, especially benefiting those with weaker spatial abilities. In collaboration with Lipscomb …

The Fascia Iliaca Regional Nerve Block Using Ultrasound And Landmark Technique: An Objective Structured Clinical Examination For Nurse Anesthetists, Braxton T. Beech, Parker F. Rigby

Doctoral Projects

The fascia iliaca block (FIB) is an effective regional anesthesia technique used in various clinical settings, including operating rooms, emergency departments, and pain management clinics. Despite its advantages in reducing postoperative complications and minimizing opioid use, FIB remains underutilized among Certified Registered Nurse Anesthetists (CRNAs), primarily due to limited exposure and training. This doctoral project examines the implementation of an Objective Structured Clinical Examination (OSCE) as an educational intervention to enhance CRNA proficiency in performing FIB using both ultrasound-guided and landmark techniques.

A pre- and post-test study design was conducted with 18 CRNA participants attending a continuing education workshop. Demographic …

Even Flow, Marianne Koleng

be Still

This piece attempts to connect the "ebb and flow" of music and art with the sometimes strict interpretation of anatomy. It calls to attention what often seem as opposites - the cold nature of medicine and science with the seemingly warm and free nature of music and art. While many see them as opposites, this piece attempts to convey they are really two sides of the same coin.

Determining The Effects Of An Hiv Infective Model On The Development Of Neuropathic Pain In Alzheimer’S Disease Model Mice., Ayesha Usman, Megan W. Szobody, Jose Rios, Mohammed Alnoud, Khalid Benamar

Research Colloquium

The purpose of this study is to determine the effect of the Human Immunodeficiency virus (HIV) in producing neuropathic pain in an Alzheimer’s Disease (AD) mouse model. HIV-1 envelope glycoprotein gp120 is correlated with increased release of thermal hyperalgesia and mechanical allodynia mediators from astrocytes and glial cells in rodents, producing the identifiable symptoms of neuropathic pain. Similarly, studies show that 45.8% of AD patients experience chronic pain. The production of an HIV/AD comorbid mouse model will be useful in determining important pathological pathways for neuropathic pain and is vital to future studies in therapeutic approaches to these conditions. Two …

Upregulating Ankhd1 In Ps19 Mice Reduces Tau Phosphorylation And Mitigates Tau Toxicity-Induced Cognitive Deficits, Xiaolin Tian, Nathan Le, Yuhai Zhao, Dina Alawamleh, Andrew Schwartz, Lauren Meyer, Elizabeth Helm, Chunlai Wu

School of Graduate Studies Faculty Publications

Using the fly eye as a model system, we previously demonstrated that upregulation of the fly gene mask protects against FUS- and Tau-induced photoreceptor degeneration. Building upon this finding, we investigated whether the protective role of mask is conserved in mammals. To this end, we generated a transgenic mouse line carrying Cre-inducible ANKHD1, the human homolog of mask. Utilizing the TauP301S-PS19 mouse model for Tau-related dementia, we found that expressing ANKHD1 driven by CamK2a-Cre reduced hyperphosphorylated human Tau in 6-month-old mice. Additionally, ANKHD1 expression was associated with a trend toward reduced gliosis and preservation of the presynaptic marker Synaptophysin, suggesting …

Progressive Multifocal Leukoencephalopathy (Pml) Induced By Jc Virus: A Case Report And Review Of Clinical Implications, Hugo Zamarron, Roberto Cruz

Research Symposium

Background: Progressive multifocal leukoencephalopathy (PML) is a rare but serious demyelinating disease of the central nervous system, caused by the John Cunningham (JC) virus. While the JC virus is common in the general population, it remains dormant in healthy individuals but can reactivate in immunocompromised patients, particularly those with HIV/AIDS or undergoing immunosuppressive treatments for organ transplants or autoimmune conditions. The virus attacks oligodendrocytes, leading to demyelination and significant neurological deficits. Immunosuppressive therapies such as natalizumab, rituximab, and mycophenolate increase the risk of PML. Diagnosing PML is challenging as its symptoms—focal neurological deficits, sensory-motor issues, and visual disturbances—overlap with conditions …

Coronary Artery Disease – Future Tools For Optimizing Primary Prevention, Nick Makosiej

Capstone Showcase

Coronary artery disease (CAD) is a progressive, obstructive, and inflammatory process affecting the endothelial lining of the coronary arteries, which ultimately compromises the perfusion of the myocardium and can lead to ischemic infarction. This narrowing of vasculature which supplies the myocardial tissue leads to a spectrum of anginal syndromes and inevitably, catastrophic consequences. This article is focused on understanding the pathophysiology of this disease process and educating providers on emerging clinical tools that can be utilized to prevent progression, and ultimately reduce morbidity and mortality of this insidious disease process.

Development Of The Mechanoresponsive Pericellular Matrix Of Chondrons, Donghee Lee, Sydney E. Greer, Andrew T. Dudley

Journal Articles: Genetics, Cell Biology & Anatomy

Physical properties of cartilage are conferred by the composition and ultrastructure of the extracellular matrix. This study focuses on the development of the pericellular matrix (PCM), a domain that directly contacts the chondrocyte and is a key regulator of biomechanical and biochemical signaling. Using three-dimensional cell culture, microfluidic cell compression platforms, and genetic mouse models, we demonstrated that collagen VI is initially assembled at the cell surface and then displaced to form a shell at the PCM-territorial matrix boundary. Cell surface-bound hyaluronan is crucial for the assembly process, and hyaluronan-aggrecan complexes drive displacement. Integrin adhesion is not required early but …
