Differentiating Axonal From Demyelinating Neuropathies Using Multiparametric Quantitative Mri Of Peripheral Nerves, Jacob D. Baraz, Stephanie Xuan, Sadaf Saba, Xue Yang, Ryan Castoro, Yang Xuan, Alison Roth, Richard D. Dortch, Jun Li, Yongsheng Chen

Medical Student Research Symposium

Objectives: To develop a multiparametric quantitative MRI (qMRI) method to track pathological changes in the peripheral neuropathies.

Background: Irrespective of the causes or types of polyneuropathies, peripheral nerves are mainly afflicted by two kinds of pathologies – axonal loss and demyelination. It is critical to differentiate between the two as treatments are different for the two conditions. While nerve conduction studies (NCS) have been used to differentiate the two pathologies in the distal nerves, there are no tools to probe the pathologies in the proximal peripheral nerves. This is particularly needed when distal nerves become non-responsive in NCS.

Methods: We …

Digital 3d Brain Mri Arterial Territories Atlas, Chin-Fu Liu, Johnny Hsu, Xin Xu, Ganghyun Kim, Shannon M. Sheppard, Erin L. Meier, Michael I. Miller, Argye E. Hillis, Andreia V. Faria

Communication Sciences and Disorders Faculty Articles and Research

The locus and extent of brain damage in the event of vascular insult can be quantitatively established quickly and easily with vascular atlases. Although highly anticipated by clinicians and clinical researchers, no digital MRI arterial atlas is readily available for automated data analyses. We created a digital arterial territory atlas based on lesion distributions in 1,298 patients with acute stroke. The lesions were manually traced in the diffusion-weighted MRIs, binary stroke masks were mapped to a common space, probability maps of lesions were generated and the boundaries for each arterial territory was defined based on the ratio between probabilistic maps. …

Higher Sexual Excitation Is Associated With An Increase In Sex-Linked Substance Use In Women With A History Of Unwanted Sexual Contact, Harper R. Jones, Tierney K. Lorenz

Center for Brain, Biology and Behavior: Papers & Publications

Survivors of unwanted sexual contact have an increased likelihood of using substances in sexual situations, which puts them at heightened risk for intoxication-related harms. Separately, research has indicated that women may intentionally use substances in sexual situations to either enhance pleasure (i.e., increase sexual excitation) and/or reduce sexual anxiety or shame (i.e., reduce sexual inhibition), a phenomenon termed sex-linked substance use (SLSU). A predominant assumption in the literature is that women with unwanted sex histories are more likely to disengage during sex, suggesting greater inhibition-related SLSU; however, there is little prior research directly examining if women who have unwanted sex …

Use Of Integrated Clinical Scenarios In Neuroanatomy Laboratory Sessions A Strategy To Foster Students’ Learning, Ahmed Yaqinuddin, Amna Siddiqui, Muhammad Faisal Ikram, Junaid Kashir

International Journal of Health and Allied Sciences

Objective: Combinations of various teaching strategies have been employed to enhance neuroanatomy teaching, to little success. Herein, we describe the use of integrated clinical scenarios in anatomy laboratory sessions as an educational strategy to improve the learning process for students undertaking neuroscience course. Methods: We assessed the perception and performance of students who utilised the integrated clinical resources in the neuroanatomy labs. We also compared the performance of the students on their neuroscience course with the performance of the previous year's students (who did not use the clinical scenarios). Results: A total of (130) 88% of the registered student both …

The Clinical Value Of Oculomotor Assessments Across The Continuum Of Concussion, Dillon Richards

Electronic Thesis and Dissertation Repository

Concussions are complex conditions that are difficult to manage medically. Variations in symptom presentation, intricate neurophysiological processes, and the availability of a variety of possible assessment tools may contribute to this complexity. Clinicians must use a broad approach, employing both subjective symptom assessment and objective assessments to confirm a diagnosis and/or monitor progression and recovery. Oculomotor function after concussion may be an important indicator of injury, given the interconnectedness of oculomotor function, vestibulo-ocular and visual systems, and even cognition. Oculomotor function may be assessed objectively or indirectly using patient-reported symptom checklists as part of subjective assessments. One way of objectively …

Evaluation Of Respiratory Function Using Blood Gas Parameters In Yucatan Minipigs Following Spinal Cord Injury, Jackson Gallagher, Monique Morgan, Chase Knibbe, Destiny Gibson, Maxwell Boakye

The Cardinal Edge

There are approximately 17,810 new spinal cord injuries (SCI) in the U.S. each year [1]. Physical damage to the spinal cord has the potential to interfere with normal motor, sensory, and/or autonomic function, such as impairment of the respiratory system. In fact, respiratory insufficiency is the number one cause of mortality and morbidity after SCI. The more rostral the injury, the more likely there will be disruption to normal ventilation (generally rostral to T6) [2]. To conduct relevant preclinical research, it has been shown that large animal models, such as the Yucatan minipig, have a better success rate of translating …

Explicit And Implicit Emotion Processing In The Cerebellum: A Meta‑Analysis And Systematic Review, Jordan E. Pierce, Marine Thomasson, Philippe Voruz, Garance Selosse, Julie Péron

Center for Brain, Biology and Behavior: Papers & Publications

The cerebellum’s role in affective processing is increasingly recognized in the literature, but remains poorly understood, despite abundant clinical evidence for affective disruptions following cerebellar damage. To improve the characterization of emotion processing and investigate how attention allocation impacts this processing, we conducted a meta-analysis on task activation foci using GingerALE software. Eighty human neuroimaging studies of emotion including 2761 participants identified through Web of Science and ProQuest databases were analyzed collectively and then divided into two categories based on the focus of attention during the task: explicit or implicit emotion processing. The results examining the explicit emotion tasks identified …

Mild Traumatic brain injury (mTBI) is a signature wound in military personnel, and repetitive mTBI has been linked to age-related neurogenerative disorders that affect white matter (WM) in the brain. However, findings of injury to specific WM tracts have been variable and inconsistent. This may be due to the heterogeneity of mechanisms, etiology, and comorbid disorders related to mTBI. Non-negative matrix factorization (NMF) is a data-driven approach that detects covarying patterns (components) within high-dimensional data. We applied NMF to diffusion imaging data from military Veterans with and without a self-reported TBI history. NMF identified 12 independent components derived from fractional …

The Role Of Reported Affective Symptoms And Anxiety In Recovery Trajectories After Sport-Related Concussion, Bernadette A. D'Alonzo, Abigail C. Bretzin, Douglas J. Wiebe, Ivy League–Big Ten Epidemiology Of Concussion Study Investigators, Arthur C. Maerlender, Cary R. Savage

Center for Brain, Biology and Behavior: Papers & Publications

Background: There is growing awareness and clinical interest in athletes with affective symptoms after sport-related concussion (SRC), as these symptoms may contribute to overall symptoms and represent a modifiable risk factor of longer recovery. However, evidence of their effects on the entire return-to-play (RTP) trajectory, particularly among women and men, is limited.

Purpose/Hypothesis: To examine the relationship between affective symptom reporting and RTP progression after SRC among a cohort of Division 1 student-athletes. We hypothesized that those endorsing affective symptoms, specifically nervous-anxious symptoms, spend more time in RTP progression and recovery.

Study Design: Cohort study; Level of evidence, 3.

Methods: …

Expression And Purification Of The Bacterial Protein Curli Csga And Its Cross-Interactions With Amyloid-B, Leah Grace Cantrell

Honors Theses

One of the main causes of neurodegenerative diseases is aggregation of amyloid proteins that are toxic to the neurons. Proteins like amyloid-β (Aβ) and α-syneuclein (α-syn) form hallmark aggregate lesions that contribute to pathological processes in the brain in Alzheimer and Parkinson’s patients, respectively. Recent ground-breaking studies have suggested a link between the microbiota of the gut and neurodegenerative diseases, called the “gut-brain axis.” It has been long known that the protein, CsgA found in many enteric bacteria, forms amyloid fibers of its own called Curli. Curli fibrils are a structural component of bacterial colonies and maintain the integrity of …

From Young To Old: The Effects Of Sedentary-Aging And Exercise Interventions On Structural Plasticity Of Lumbar Motor Neurons, Nmj, And Glial Cell Line-Derived Neurotrophic Factor Expression, Alberto Felipe Cintron-Colon

Dissertations

Neuromuscular weakness has been associated with age progression. A possible reason is a disconnection between muscle and neuron, causing components from both the central and peripheral nervous systems to deteriorate. Exercise, however, has beneficial effects for both muscle and nervous tissue, inducing neuroprotection. Neurotrophic factors are powerful regulators of neuronal maintenance and synaptic strength. Glial cell line-derived neurotrophic factor (GDNF) is a neurotrophic factor that has been shown to be a potent survival factor for somatic motor neurons that innervate skeletal muscle.

This study aims to evaluate changes in structural plasticity of motor neurons in the lumbar spinal cord and …

Comparative Studies Between The Murine Immortalized Brain Endothelial Cell Line (Bend.3) And Induced Pluripotent Stem Cell-Derived Human Brain Endothelial Cells For Paracellular Transport, Jiahong Sun, Weijun Ou, Derick Han, Annlia Paganini-Hill, Mark J. Fisher, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Brain microvascular endothelial cells, forming the anatomical site of the blood-brain barrier (BBB), are widely used as in vitro complements to in vivo BBB studies. Among the immortalized cells used as in vitro BBB models, the murine-derived bEnd.3 cells offer culturing consistency and low cost and are well characterized for functional and transport assays, but result in low transendothelial electrical resistance (TEER). Human-induced pluripotent stem cells differentiated into brain microvascular endothelial cells (ihBMECs) have superior barrier properties, but the process of differentiation is time-consuming and can result in mixed endothelial-epithelial gene expression. Here we performed a side-by-side comparison of the …

Effect Of Osteopathic Manipulative Treatment In Patients With Postural Orthostatic Tachycardia Syndrome (Pots): A Literature Review, Sidharth Sahni, Harrison Jordan, Binoy Desai, Danielle Cooley, Alexander King

Stratford Campus Research Day

Postural Orthostatic Tachycardia Syndrome (POTS) is characterized by autonomic dysregulation resulting in diminished blood flow and excessive tachycardia.

POTS has been scarcely studied in the clinical setting. A review of literature generated only four articles, only one of which met the established criteria.

A follow up study to evaluate the effect of OMT on the quality of life for patients with POTS is planned. The hypothesis is that osteopathic manipulation plays a role in the management of POTS, as patients should experience improvement in their symptoms and their overall quality of life.

Examining Levels Of Catecholamine Neurotransmitter Regulatory Proteins Within The Prefrontal Cortex Of Rodents Following Traumatic Brain Injury, Eleni Papadopoulos, Christopher P. Knapp, Claire M. Corbett, Jessica Loweth, Rachel L. Navarra

Stratford Campus Research Day

Traumatic brain injury (TBI) resulting from impact to the head can cause long lasting impairments of cognitive processes that lead to increased risk-taking behavior in clinical populations. Our laboratory has recently shown that female, but not age-matched male, rats increase preference for risky choices after multiple experimentally-induced mild TBI’s. Our overarching goal is to understand the neural mechanisms underlying TBI-induced increases in risk-taking behavior.

The prefrontal cortex (PFC) plays a prominent role in risk-based decision making. Sub[1]regions of the PFC include the medial PFC (mPFC), the orbitofrontal cortex (OFC), and the anterior cingulate cortex (ACC), and these sub[1]regions play specific …

Effective Therapies And Nursing Approaches: Improving Cognition In Older Adult Stroke Patients, Selyna Baltazar

Nursing | Senior Theses

Background

Ischemic stroke occurs in thousands of older adults throughout the year. Due to the lack of oxygen entering the brain, many patients experience a decline in cognitive function due to ischemic stroke. Cognition is the ability to understand, learn, and remember information which is needed for completing daily tasks. Modern technology has allowed for patients to survive ischemic strokes but has yet to provide proper screening tools and methods for stroke-related cognitive impairment.

Objective

To investigate the best practices for identifying, treating, and caring for patients with a cognitive injury related to a stroke. A review of the research …

Adults With Sensory Defensiveness And Their Use Of Coping Strategies, Cassidy Mccurdy, Sonia Patiño, Julia Mcmahon, Sophia Hagen

Occupational Therapy | Graduate Capstone Projects

Purpose: The purpose of this study was to develop and pilot a questionnaire examining the relationship between sensory defensiveness and coping strategies, as well as establish typical ratings for sensory defensiveness among the adult population. Methods: Through snowball sampling, 91 participants completed the Sensory Response Questionnaire containing 69 questions. Participants’ responses to questions concerning sensations and coping strategies in various situations indicated levels of sensory defensiveness. Levels of sensory defensiveness were determined by mean ratings: < 2 low sensory defensiveness (Low SD), 2-2.5 some sensory defensiveness (Some SD), > 2.5 moderate sensory defensiveness (Moderate SD). Discussion: Kinnealy et al. (1995), estimates that 15% of the population has some level of sensory defensiveness that impacts …

Regaining Effort-Based Food Motivation: The Drug Methylphenidate Reverses The Depressive Effects Of Tetrabenazine In Female Rats, Deanna Pietrorazio

Honors Scholar Theses

Tetrabenazine (TBZ), a vesicular monoamine transporter type 2 (VMAT-2) inhibitor, depletes dopamine and induces motivational deficits and other depressive symptoms in humans. Methylphenidate (MPH) is a dopamine transport blocker that is used to enhance motivational function. Previous studies have shown that in male rats, TBZ induces a shift in effort-related choice such that a low-effort bias is induced. In male rats this occurs at a dose range of 0.75-1.0 mg/kg TBZ, and this effect is reversible with co-administration of MPH. Recent studies have shown that females need a higher dose of TBZ (2.0 mg/kg) to show the low-effort bias. The …
