Intrinsic Measures And Shape Analysis Of The Intratemporal Facial Nerve, Thomas Hudson, Bradley Gare, Daniel Allen, Hanif Ladak, Sumit Agrawal

Electrical and Computer Engineering Publications

Hypothesis: To characterize anatomical measurements and shape variation of the facial nerve within the temporal bone, and to create statistical shape models (SSMs) to enhance knowledge of temporal bone anatomy and aid in automated segmentation.

Background: The facial nerve is a fundamental structure in otologic surgery, and detailed anatomic knowledge with surgical experience are needed to avoid its iatrogenic injury. Trainees can use simulators to practice surgical techniques, however manual segmentation required to develop simulations can be time consuming. Consequently, automated segmentation algorithms have been developed that use atlas registration, SSMs, and deep learning.

Methods: Forty cadaveric temporal bones were …

Seen In Science: Lgbtq+ Inclusivity In Anatomy & Physiology Texts, Harshini Sirvisetty, Kat Ray King, Linda Catherine Fuselier

Undergraduate Arts and Research Showcase

Biology is unique from other science disciplines in that concepts taught in core classes can inform our student’s understanding of sex and gender. A biology major encounters lessons on sex determination, sexual reproduction, and sex characteristics in their courses. The language used in these units matters. It is imperative that educators consider how the language, examples, and content that we use in classrooms drive (or not) inclusivity for gender- and sexuality-diverse (GSD) (aka LGBTQ+) individuals. We chose to analyze four college-level human anatomy/physiology (AP) textbooks for GSD population inclusivity. We adopted a queer theory framework to critically examine how sex, …

Promotion Of Neuronal Regeneration: Upregulation Of Intrinsic Neuronal Growth Capacity Versus Microtubule Stabilization, Cathy Le

Honors Undergraduate Theses

Central Nervous System (CNS) injury may lead to irreversible damage to cognitive and motor abilities when injured. This is due to the inability of axons to regenerate. This thesis focuses on two methods of promoting axonal regeneration: microtubule stabilization and upregulation of the intrinsic growth capacity of the neuron via the mechanistic target of rapamycin (mTOR) pathway. Both have shown promising results in potentially being a therapeutic treatment for CNS trauma. This research seeks to (1) test a combinatorial method of axonal regeneration utilizing both methods simultaneously and (2) compare microtubule stabilization and upregulation of the mTOR pathway as neuronal …

Left Ventricular Strains During Late Filling In A Preclinical Model, Saar Peles

Honors Undergraduate Theses

Understanding the mechanisms governing left ventricular function and dysfunction is critical to analyze cardiovascular disorders and gaining insights into possible therapies. Left ventricular function can be evaluated using Magnetic Resonance Imaging (MRI). Cardiac displacements and corresponding strains are then computed from the imaging data. In measuring and assessing the left ventricle’s motion, images are taken either in the short axis (top-down) or long axis (side) views. In this project, we will use DENSE MRI data, which measures the displacements of individual tissue voxels during the cardiac cycle.

After extracting the myocardial tissue by segmenting the MR images, strains are computed …

Feasibility Of A Readiness Exam For Predicting Radiography Program Success: A Pilot Study, Tammy L. Webster, Sarah B. Mcbrien, Gregory M. Mehrer, Harlan R. Sayles

Internet Journal of Allied Health Sciences and Practice

ABSTRACT

Background: Research investigating predictors of academic success in rigorous health science education is valuable for curricular intervention for identified at-risk students. Various predictors of success have been investigated, but the literature is insufficient when examining anatomy and physiology readiness scores as they correlate to radiography curricular success. This pilot study assessed the correlation between readiness exam scores and programmatic course GPA to determine if the scores could be used as a metric for identifying academic success resources for incoming students. Cohorts of the radiography program at a midwestern health sciences center demonstrated a longitudinal trend of difficulty with anatomy …

Modulation Of Parasympathetic Reactivation Post-Exercise Via Slow Breathing, Brent Burg

CSB and SJU Distinguished Thesis

During exercise sympathetic nervous activity increases and parasympathetic nervous activity decreases to fuel energy demands. Heart rate variability (HRV) indicates activity of the autonomic nervous system and the balance of its two branches. Slow breathing (SB) (6 breaths/minute) increases parasympathetic activity both spontaneously during practice and at rest after long-term practice. Thus, SB may increase parasympathetic activity after exercise. PURPOSE: This study aimed to determine whether post-exercise SB increases parasympathetic activity as measured by HRV. METHODS: Ten recreationally active college aged males (21 +/-1 years old) completed the study. A VO2max test was used to determine 70% of VO2max for …

Distal Urogenital Anatomy Of Male Prairie Racerunners, Aspidoscelis Sexlineatus Viridis (Reptilia: Sauria: Teiidae), Stanley E. Trauth

Journal of the Arkansas Academy of Science

I examined histologically the distal urogenital anatomy in male Prairie Racerunners (Aspidoscelis sexlineatus viridis) from a small seasonal sample of individuals collected in Arkansas in order to provide additional information regarding squamate urogenital anatomy. Specifically, I focused on the basic anatomy and positioning of posterior ducts and associated structures in this teiid lizard. The anatomical structures included the ductus deferens, ampulla ductus deferens, ampulla urogenital papilla (Aup), ureter, inner core tissue mass, urodaeum, and the urogenital papilla. The two Aup, which are small complimentary blind pouches representing the terminal repositories for products released by urogenital ducts, are striking …

Associations Between Sleep And In-Race Gastrointestinal Symptoms: An Observational Study Of Running And Triathlon Race Competitors, Patrick Benjamin Wilson

Human Movement Studies & Special Education Faculty Publications

OBJECTIVE: It remains unstudied whether poor sleep is involved in the etiology of gastrointestinal (GI) problems in athletes.

METHODS: Eighty-seven running and triathlon/duathlon race (>60 minutes) participants completed questionnaires to quantify the Sleep Problems Index-(SPI)-I and sleep parameters from the night before races. For GI symptoms, participants reported the severity (0-10 scale) of four upper and three lower symptoms during races. Spearman's correlations examined whether sleep measures were associated with in-race GI symptoms. Partial correlations were calculated to control for age, resting GI symptoms, and anxiety.

RESULTS: SPI-I scores correlated with in-race upper GI symptoms (rho=0.26, p=0.013). Controlling for …

The Hsp90 Inhibitor, Auy-922, Ameliorates The Development Of Nitrogen Mustard-Induced Pulmonary Fibrosis And Lung Dysfunction In Mice, Pavel Solopov, Ruben M.L. Colunga Biancatelli, Margarita Marinova, Christiana Dimitropoulou, John D. Catravas

Bioelectrics Publications

Increased levels of heat shock protein 90 (HSP90) have been recently implicated in the pathogenesis of pulmonary fibrosis and the use of HSP90 inhibitors constitutes a potential therapeutic approach. Similarly, acute exposure to nitrogen mustard (NM) is related to the development of chronic lung injury driven by TNF-α, TGF-β, ERK and HSP90. Thus, we developed a murine model of NM-induced pulmonary fibrosis by instilling C57BI/6J mice with 0.625 mg/kg mechlorethamine hydrochloride. After 24 h, mice began receiving AUY-922, a second generation HSP90 inhibitor, at 1 mg/kg 2 times per week or 2 mg/kg 3 times per week, for either 10 …

Hsp90 Inhibitors For Ipf/Covid-19, Ruben Manuel Luciano Colunga Biancatelli, Pavel A. Solopov, John Catravas

Bioelectrics Publications

Heat shock protein 90 (HSP90) is an important chaperone that assists the late stage folding of several proteins involved in cell survival in response to environmental stressors. The inhibition of HSP90 is followed by a complex modulation of the proteome and the kinome, that has proved beneficial in cancer and various neurodegenerative diseases. Additionally, accumulating literature suggests that HSP90 may be a key target during the development of pulmonary fibrosis and that its inhibition could serve as a new and exciting therapeutic approach. We have summarized the current evidence about HSP90’s role in Idiopathic Pulmonary Fibrosis (IPF), the results from …

Determining Effects Of The Paf-R And Anti-Hypertensive Drugs Mediated Microvesicle Particle Release In Modulating Anti-Tumor Response Of Lung Cancer, Andrew Stephen Forino

Browse all Theses and Dissertations

Lung cancer is one of the world’s leading causes of cancer-related deaths with poor prognosis, and difficult to treat malignancy. Several genetic, and environmental factors including cigarette smoking and hypertension have been linked as the common risk factors for lung cancer. To that end, multiple mechanisms have been proposed in regulating tumor growth, angiogenesis, and metastasis, as well as the efficacy of cancer therapy in experimental lung cancer models. Importantly, studies including ours, have shown that exposure to reactive oxygen species (ROS)-generating stimuli such as cigarette smoking, and cancer therapy produced oxidized lipids with platelet-activating factor (PAF) agonistic activity from …

Discovery And Characterization Of Pathways Involved In Fus And Tdp43-Induced Toxicity In Yeast, Weston Joseph Shaw

Browse all Theses and Dissertations

High-throughput genome-scale studies are becoming increasingly common as a means to discover genetic interactions. This methodology is particularly efficient when performed in the budding yeast Saccharomyces cerevisiae. Here, we (1) overexpress a large human gene library in yeast to assess how many of them are toxic, and (2) use the list of genes generated above to refine and analyze human genes previously identified to enhance toxicity of two ALS-associated proteins, FUS and TDP-43. By introducing each of 13,500 human genes into yeast, we demonstrated that the majority of these genes (about 97%) are not toxic to yeast when overexpressed. These …

Characterization Of B3galt2 And Heg1 Expression In Dorsal Root Ganglia, Alexander H. Nguyen

Browse all Theses and Dissertations

Proprioception provides unique sensory feedback about the body’s orientation in space and this sensation is essential for creating specific motor functions and coordinated movement. During neurogenesis, unique genetic markers are expressed and classified as early, transient/middle, and late markers depending on their timing of expression. This study focuses on the expression patterns of two late markers: Heg1 and B3galt2. We investigated how expression of these two markers respond to peripheral nerve injury (PNI). We cloned and generated riboprobes to detect expression of B3galt2 and Heg1 in DRGs using in situ hybridization after transection of the sciatic nerve. B3galt2 hybridization in …

Help-Seeking Behaviour For Fatigue In Inflammatory Bowel Disease, Doireann Ní Dhálaigh

Theses

Background: Fatigue is a common and burdensome symptom of inflammatory bowel disease (IBD). Although many symptoms of IBD can be debilitating, fatigue is reported to be the most burdensome. It is experienced by up to 86% of people in active disease and 41-48% in remission and impacts greatly on all aspects of people’s lives. Fatigue is an invisible symptom and can often be overlooked by healthcare professionals. Since it is invisible, it can only be made known to healthcare professionals if patients seek help for it. This study aims to explore the determinants of help-seeking behaviour for fatigue in IBD …

A Case Study On Accessible Reading With Deaf Children, Jody H. Cripps, Samuel J. Supalla, Laura A. Blackburn

Communication Disorders & Special Education Faculty Publications

The concept of accessible reading for deaf students is new and worthy of exploration. In the face of the reading difficulties often experienced by deaf students, the lack of a specialized reading methodology that works for them must be addressed. Central to the paper is a research case study undertaken with two young deaf students, proficient in American Sign Language (ASL) and learning to read. The students participated in a tutorial with a tutor knowledgeable in a specialized reading methodology called ASL Gloss. The participating students demonstrated progress in reading skills over time.

Statistical Analysis Of Fnirs Data: Consideration Of Spatial Varying Coefficient Model Of Prefrontal Cortex Activity Changes During Speech Motor Learning In Apraxia Of Speech, Rachel Johnson, Jennifer Matthews, Norou Diawara, Rachel Carroll

Communication Disorders & Special Education Faculty Publications

Apraxia of speech is an impairment in the planning and programming of speech typically accompanied by aphasia (language impairment) secondary to a left hemisphere stroke. It is unknown if the structural and functional connections to the damaged area implicate the integrity of the cognitive functions of the prefrontal cortex (PFC). The present study examines the feasibility of measuring hemodynamic activity in the PFC in response to the structure of practice and during treatment. This multiple-baseline single case-design study involving two individuals with chronic acquired apraxia of speech measured the hemodynamic changes in PFC activity during treatment across the intervention period …

Inter-Rater Reliability And Intra-Rater Reliability Of Synchronous Ultrasound Imaging And Electromyography Measure Of The Lumbopelvic-Hip Muscle Complex, Courtney Caputo

Honors Undergraduate Theses

Objective: The purpose of this study was to determine inter-rater and intra-rater reliability of synchronous ultrasound imaging and electromyography measures of lumbopelvic-hip muscle activity performed by a novice and an experienced investigator in healthy individuals. Electromyography (EMG) has served as the gold standard for quantification of onset of muscle activation; however, ultrasound imaging can visualize muscle activity when collected simultaneously. Methods: A novice and experienced investigator collected a series of 3 ultrasound images at rest and 3 M-mode clips during contraction of each muscle while EMG electrodes collected muscle activity. Muscles collected included: external oblique, erector spinae, rectus abdominis, gluteus …

Bioelectrics Publications

Insulinoma is an insulin-producing pancreatic neuroendocrine tumor that can be malignant in about 10% of cases. Locoregional invasion, lymph node metastases, or remote metastases are the main criteria of malignant insulinoma. Its incidence in patients with pre-existing diabetes mellitus (DM) is exceptionally rare. In this report, we describe a 66-year-old man with long-standing type 2 DM who presented with recurrent episodes of diaphoresis due to severe hypoglycemia despite the withdrawal of insulin therapy, hypercalcitoninemia, and biochemical and radiological findings suggestive of metastatic malignant insulinoma. Unfortunately, after few days of diazoxide treatment, edema, hypotension, oliguria, and water retention were observed, patient’s …
