Clearance Of Neutrophils From Ich-Affected Brain By Macrophages Is Beneficial And Is Assisted By Lactoferrin And Cd91, Xiurong Zhao, Shun-Ming Ting, Guanghua Sun, Jesus Bautista Garrido, Lidiya Obertas, Jaroslaw Aronowski

Faculty, Staff and Student Publications

Background: Within hours after intracerebral hemorrhage (ICH) onset, masses of polymorphonuclear neutrophils (PMNs) infiltrate the ICH-affected brain. After degranulation involving controlled release of many toxic antimicrobial molecules, the PMNs undergo rapid apoptosis and then are removed by phagocytic microglia/macrophages (MΦ) through a process called efferocytosis. Effective removal of PMNs may limit secondary brain damage and inflammation; however, the molecular mechanisms governing these cleanup activities are not well understood. We propose that scavenger receptor CD91 on myeloid phagocytes especially in presence of CD91 ligand, LTF (lactoferrin, protein abundant in PMNs), plays an important role in clearance of dead apoptotic PMNs (ANs). …

Psychology Faculty Publications

Background

Large-scale cohort and epidemiological studies suggest that PTSD confers risk for dementia in later life but the biological mechanisms underlying this association remain unknown. This study examined this question by assessing the influences of PTSD, APOE ε4 genotypes, DNA methylation, and other variables on the age- and dementia-associated biomarkers Aβ40, Aβ42, GFAP, NfL, and pTau-181 measured in plasma. Our primary hypothesis was that PTSD would be associated with elevated levels of these markers.

Methods

Analyses were based on data from a PTSD-enriched cohort of 849 individuals. We began by performing factor analyses of the biomarkers, the results of which …

Neuroticism Mediates The Association Between Autistic Traits And Choice Reaction Time Among Young Adults, Kassandra De Jesus Cintron, Xiao Yang

Psychology Faculty Publications

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that influences an individual’s cognitive functions and social interaction. While most studies have focused on children and adolescents diagnosed with ASD, elevated levels of autistic traits in subclinical populations may also influence individuals’ daily functioning. Autistic traits are also linked to the Big Five personality. In particular, neuroticism (emotion instability) has been shown to be positively associated with autistic traits, which may contribute to behavioral symptoms of autistic traits. The present study aimed to investigate the association between autistic symptoms and sensorimotor processing among a subclinical population. One hundred young adults (M …

Peripheral Nerve Stimulation After Total Knee Arthroplasty And Non-Operable Patella Fracture, Peter D Vu, Farah Gul, Christopher L Robinson, Grant H Chen, Jamal Hasoon

Faculty, Staff and Student Publications

Chronic knee pain, affecting over 25% of adults in the United States, has surged by 65% over the past two decades leading to rising functional deficits, mobility problems, and a diminished quality of life. While conservative management with pharmacologic and minimally invasive injections are pursued early in the disease process, total knee arthroplasty for refractory osteoarthritis of the knee is often considered. This procedure usually improves pain and functionality within the first three months. However, a significant portion of patients often suffer from postoperative pain that can become chronic and debilitating. We detail the case of a patient with a …

Co-Occurrence Of Autism Spectrum Disorder And Attention-Deficit/Hyperactivity Disorder With Idiopathic Hypersomnia: Data From The Hypersomnia Foundation Registry, Sophie Sevan Mikkelsen

Honors Undergraduate Theses

In recent years, hypersomnia patients and researchers alike have increasingly discussed the possibility of heightened comorbidities, or co-occurrences, of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) with the central disorders of hypersomnolence: idiopathic hypersomnia (IH) and narcolepsy (N). While a few scarce studies have investigated a link between ADHD and N, there has been no research on the co-occurrence of these conditions with IH. This study, using data from the Hypersomnia Foundation’s CoRDS Patient Registry, is the first to identify self-reported rates of ASD and ADHD diagnoses by people with idiopathic hypersomnia. Four chi-square tests were conducted to determine …

Taste And Learning In The Gustatory Cortex, Martin Raymond

Alternative Theses and Dissertations (AETDs)

This research investigates the organization of taste representations in the gustatory cortex (GC) through two experiments utilizing miniscope imaging in mice. The first experiment focuses on conditioned taste aversion (CTA) and reveals that taste representations in GC are heavily dominated by palatability, with shifts in representational space occurring as a function of learning and extinction. The second experiment explores the interrelation of aversive stimuli, the impact of novelty on taste representations, and the role of somatosensory feedback. Findings suggest that familiarity and palatability emerge as positive signals with experience, shaping taste representations in GC. The study contributes to a nuanced …
