Evaluating Sensory Sensitivities Among Children With Autism Spectrum Disorder In An Adaptive Gymnastics Program, Aicha Kaouss, Bradley Eppinger, Austin Ebbrecht, Kailash Ram, Kaitlin P. Hardy Md

Knowledge and Creativity Expo

Introduction: Children with autism spectrum disorder (ASD) participate in physical activity at lower rates than their neurotypical peers1. Sensory sensitivities, reported in approximately 75–95% of children with ASD, may contribute to this disparity2. Gymnastics environments involve bright lighting and loud noise, which can precipitate sensory overload. The impact of specific sensory features on participation in adaptive gymnastics remains underexplored.

Methods: A cross-sectional study recruited caregivers of children aged 3–12 years with an ASD diagnosis enrolled in the EVMS Adaptive Gymnastics Program. Caregivers completed the Sensory Experiences Questionnaire–Third Edition (SEQ-3)3 and supplemental survey items on Redcap which assessed environmental triggers and …

Dementia Incidence In Patients With Prurigo Nodularis: An Observational Retrospective Cohort Study, Madison P. Olexson, Ana Ormaza Vera, Chunghwan Ro, Clinton W. Enos

Department Dermatology Faculty Publications

[Introduction] Prurigo nodularis (PN) is a chronic neuroinflammatory dermatosis of unknown etiology characterized by severely pruritic, symmetrically-distributed nodules with a negative impact on quality of life [1]. While some consider PN a primary idiopathic disorder, it often arises as a secondary manifestation of underlying conditions, including atopic dermatitis (AD), chronic kidney disease (CKD), human-immunodeficiency-virus (HIV), and thyroid disorders [2]. Although patients with PN are at higher risk for psychiatric comorbidities including depression, anxiety, and suicidal ideation [3] research which investigates associations between PN and neurodegenerative disorders is limited [4]. Moreover, emerging evidence implicating sustained systemic inflammation, characteristic of psoriasis and …

Stat4-Dependent Regulation Of Neuroinflammation In Atherosclerosis, Natalie Stahr, Alina K. Moriarty, Shelby D. Ma, W. Coles Keeter, Woong-Ki Kim, Larry D. Sanford, Elena V. Galkina

Department of Biomedical and Translational Sciences Faculty Publications

Atherosclerosis is linked to an increased risk of cognitive decline, with chronic inflammation being a common feature of both pathologies. IL-12 activates STAT4 to regulate myeloid cell functions, and blockade of this pathway alleviates cognitive impairment in Alzheimer's models. However, the mechanisms connecting vascular pathology to neuroinflammation remain unclear. Here, we examine whether STAT4 functions as a common mediator of neuroinflammation in atherosclerosis. We demonstrate that LysM^Cre-specific STAT4 deficiency ameliorates deficits in long-term memory in low-density lipoprotein-deficient (Ldlr^-/-) mice fed a high-fat diet (HFD-C). STAT4 deficiency moderately reduces Ser199-phosphorylated Tau burden. Atherosclerosis alters brain immune …

Hart, Bruno Manadas, João Peça, Pedro Castanheira, A. Cristina Rego

Biological Sciences Faculty Publications

Postsynaptic scaffolding protein SAP90/PSD95-associated protein 3 (SAPAP3) modulates cortico-striatal signalling and regulates the maintenance of synaptic structure. Notably, SAPAP3 defects have been reported in several human psychiatric disorders that share pathophysiological features with Huntington’s disease (HD), a neurodegenerative disorder characterized by the expression of mutant huntingtin (mHTT) and marked dysfunction of cortico-striatal synapses and mitochondria. However, the role of SAPAP3 in mitochondrial function and HD pathophysiology remains unexplored. SAPAP3 was extracted from striatal synaptoneurosomes and analyzed by SWATH-MS proteomics to identify potential interactors, revealing SAPAP3 association with several mitochondrial proteins, particularly Mic60. These data were further complemented with proximity ligation …

Stability Of Salivary Microrna Measures Across An Ncaa Division I Football Season: Implications For Microrna As A Biomarker Of Concussion, Thomas R. Campbell, Martina Zamponi, Delaney Leathers, Julie Cavallario, Jessica C. Martinez, Peter A. Mollica

Rehabilitation Sciences Faculty Publications

Background

Clinicians often face challenges in concussion care due to a heavy reliance on subjective patient input. Recently, research has sought objective biomarkers, like salivary microRNAs, to improve concussion management. However, significant limitations hinder the use of microRNAs as a diagnostic tool, including the cumulative effects of a contact sport season. A better understanding of the response to a contact sport season would help researchers and clinicians interpret expression changes at the time of injury in the context of seasonal variation. in Therefore, this study investigated the reliability of previously identified salivary microRNA targets across one contact sport season.

Excitation And Polarization Of Isolated Neurons By High-Frequency Sine Waves For Temporal Interference Stimulation, Iurii Semenov, Vitalii Kim, Giedre Silkuniene, Andrei G. Pakhomov

Bioelectrics Publications

The capacity of temporal interference (TI) stimulation to target deep brain regions without affecting nearby surface electrodes remains uncertain. Using artifact-free optical recording, we compare excitation patterns and thresholds in hippocampal neurons stimulated by “pure” and amplitude-modulated sine waves, representing TI waveforms near electrodes and at the target, respectively. We show that pure 2- and 20-kHz sine waves induce repetitive firing at rates that increase up to 60–90 Hz with stronger electric fields. Beyond this limit, action potentials merge into sustained depolarization, resulting in an excitation block. Modulating the sine waves at 20 Hz aligns firing with amplitude “beats” and …

Revealing Spatiotemporal Neural Activation Patterns In Electrocorticography Recordings Of Human Speech Production By Mutual Information, Julio Kovacs, Dean Krusienski, Minu Maninder, Willy Wriggers

Mechanical & Aerospace Engineering Faculty Publications

Background

Spatiotemporal mapping of neural activity during continuous speech production has been traditionally approached using correlation coefficient (CC) analysis between cortical signals and speech recordings. A prior study employed this approach using electrocorticography (ECoG) data from participants who underwent invasive intracranial monitoring for epilepsy. However, CC cannot detect nonlinear relationships and is dominated by the correspondence between periods of silence and of non-silence.

New Method

We introduce the mutual information (MI) measure, which can capture both linear and nonlinear dependencies. We validated CC and MI on the sub-second spatiotemporal brain activity recorded during continuous speech tasks. To refine the results, …

Obesity Prediction From Structural Mri Using Conformal Deep Learning With Uncertainty Quantification, W. Farzana, A. G. A. Temtam, B. Humud-Arboleda, L. Ma, M. Bean, F. Gerard Moeller, K. M. Iftekharuddin

Electrical & Computer Engineering Faculty Publications

Obesity arises from a neurobehavioral disorder in which the brain’s regulation of hunger and food intake is impaired, leading to an imbalance between energy consumption and expenditure. One key phenotype associated with obesity is body mass index (BMI). BMI is influenced by multiple causal pathways driven by behavioral, metabolic, and genetic factors. Traditional obesity prediction studies often rely on magnetic resonance imaging (MRI) voxel-based morphometry to correlate BMI with obesity-related clinical measurements and brain structure, predominantly gray matter volume (GMV). However, the altered brain regions are variable and widespread between studies, with some literature presenting contradictory results between BMI and …

Mimicking An Asymmetrically Walking Visual Cue Alters Gait Symmetry In Healthy Adults, Krista G. Clark, Louisa D. Raisbeck, Scott E. Ross, Christopher K. Rhea

Rehabilitation Sciences Faculty Publications

Gait asymmetries are a common problem in clinical populations, such as those with a history of stroke or Parkinson’s disease. The use of a split-belt treadmill is one way to enhance gait symmetry but relies on specialty (and typically expensive) equipment. Alternatively, visual cues have been shown as a method to alter gait mechanics, but their utility in altering gait symmetry has been relatively understudied. Before deploying this method to clinical populations, a proof-of-concept study is needed to explore using visual cues to alter gait symmetry in healthy adults. Therefore, the purpose of this study was to examine the extent …
