Faculty, Staff and Student Publications

Simple Summary

Cutaneous squamous cell carcinoma (cSCC) of the head and neck, although treatable, can be highly aggressive. Certain pathological features of cSCC can drastically impact prognosis. Therefore, the presence of a few such features is considered in both staging and treating cSCC. In this review, we summarize the current literature regarding pathological prognostic indicators of cSCC, including depth of invasion, surgical margins, perineural invasion, lymphovascular invasion, extranodal extension, tumor grade, tumor subtype, premalignant lesions, and molecular markers. Furthermore, we characterize the impact of each indicator on clinical outcomes of head and neck cSCC, their role in dictating adjuvant therapy …

BACKGROUND: Emerging biomarker technologies (e.g., MRI, EEG, digital phenotyping, eye-tracking) have potential to move the identification of autism into the first year of life. We investigated the perspectives of parents about the anticipated utility and impact of predicting later autism diagnosis from a biomarker-based test in infancy.

METHODS: Parents of infants were interviewed to ascertain receptiveness and perspectives on early (6-12 months) prediction of autism using emerging biomarker technologies. One group had experience parenting an older autistic child (n=30), and the other had no prior autism parenting experience (n=25). Parent responses were analyzed using inductive qualitative coding methods.

RESULTS: Almost …

Immunoregulatory Properties Of Immune Cells That Associate With The Lens Capsule Surface During Acute And Resolution Phases Of Experimental Autoimmune Uveitis, Phuong M. Le, Mary J. Mattapallil, Rachel R. Caspi, Mary Ann Stepp, A. Sue Menko

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Inflammation in the eye is tightly regulated to prevent vision impairment and irreversible blindness. Emerging evidence shows that immune cells are specifically recruited to the lens capsule in response to autoimmune uveitis, yet the potential that they have a role in regulating this inflammatory disease remained unexplored. Here, an immunolocalization approach combined with high-resolution confocal microscopy was used to investigate whether the immune cells that become stably associated with the lens capsule in the eyes of C57BL/6J mice with experimental autoimmune uveitis (EAU) have an immunoregulatory phenotype. These studies revealed that during the acute phase of uveitis, at day 18 …

The integration of extrinsic signaling with cell-intrinsic transcription factors can direct progenitor cells to differentiate into distinct cell fates. In the developing Drosophila eye, differentiation of photoreceptors R1-R7 requires EGFR signaling mediated by the transcription factor Pointed, and our single-cell RNA-Seq analysis shows that the same photoreceptors require the eye-specific transcription factor Glass. We find that ectopic expression of Glass and activation of EGFR signaling synergistically induce neuronal gene expression in the wing disc in a Pointed-dependent manner. Targeted DamID reveals that Glass and Pointed share many binding sites in the genome of developing photoreceptors. Comparison with transcriptomic data shows …

Companion Dogs And Depression, Anxiety, And Posttraumatic Stress Disorder In Adult Icu Survivors: A Scoping Review, Lindsey Nelson, Sue Lasiter, Amanda Emerson

People and Animals: The International Journal of Research and Practice

Intensive care unit (ICU) survivors are at risk for developing persistent psychological sequelae that have been linked to decreased quality of life and increased mortality after hospital discharge. Standardized evidence-based treatments are lacking, mainly focus on physical rather than psychological recovery, and often occur in formal settings. Benefits of human– companion dog relationships have not been explored in the ICU survivor population before. Thus, the purposes of our review were to summarize the literature focused on the influence of companion dogs on depression, anxiety, and posttraumatic stress disorder (PTSD); identify what is known about the potential role companion dogs play …

Long-Range White Matter Fibres And Post-Stroke Verbal And Non-Verbal Cognition, Rebecca W. Roth, Deena Schwen Blackett, Ezequiel Gleichgerrcht, Janina Wilmskoetter, Chris Rorden, Roger Newman-Norlund, Souvik Sen, Julius Fridriksson Ph.D., Natalie Busby, Leonardo Bonilha

Faculty Publications

Among stroke survivors, linguistic and non-linguistic impairments exhibit substantial inter-individual variability. Stroke lesion volume and location do not sufficiently explain outcomes, and the neural mechanisms underlying the severity of aphasia or non-verbal cognitive deficits remain inadequately understood. Converging evidence supports the idea that white matter is particularly susceptible to ischaemic injury, and long-range fibres are commonly associated with verbal and non-verbal function. Here, we investigated the relationship among post-stroke aphasia severity, cognition, and white matter integrity. Eighty-seven individuals in the chronic stage of stroke underwent diffusion MRI and behavioural testing, including language and cognitive measures. We used whole-brain structural connectomes …

Trim44 Enhances Autophagy Via Sqstm1 Oligomerization In Response To Oxidative Stress, Yuqin Wang, Lin Lyu, Trung Vu, Nami Mccarty

Faculty, Staff and Student Publications

The deubiquitinase tripartite motif containing 44 (TRIM44) plays a critical role in linking the proteotoxic stress response with autophagic degradation, which is significant in the context of cancer and neurological diseases. Although TRIM44 is recognized as a prognostic marker in various cancers, the complex molecular mechanisms through which it facilitates autophagic degradation, particularly under oxidative stress conditions, have not been fully explored. In this study, we demonstrate that TRIM44 significantly enhances autophagy in response to oxidative stress, reducing cytotoxicity in cancer cells treated with arsenic trioxide. Our research emphasizes the critical role of the posttranslational modification of sequestosome-1 (SQSTM1) and …

Theses and Dissertations

The United States is experiencing a maternal health crisis, which disproportionately affects Black women. Black women die from pregnancy-related causes two to three times as often as their White counter parts, and the majority of maternal death are preventable. In recent years, public health and national governing authorities have devoted resources to monitoring the health crisis and raising the public’s knowledge of warning signs; however, maternal mortality rates continue to rise. Noted contributors to Black maternal mortality include, but are not limited to, racism, delayed treatment and response to health emergencies, and lack of social and emotional support during childbirth, …

Dysregulation Of Dopamine Dynamics Through Monoamine Transporters By The Hiv-1 Protein Transactivator Of Transcription, Sarah Davis

Theses and Dissertations

Prevalence of HIV-1 Associated Cognitive Disorders (HAND) persists in the era of combined antiretroviral therapies, causing impaired memory, motor function, and decreased quality of life. Evidence from clinical samples of persons with HAND has implicated dopamine, as well as the HIV-1 viral protein transactivator of transcription (Tat) as key molecules associated with disease progression. Through molecular modeling, in vitro and in vivo mutagenesis our lab has characterized Tat as a negative allosteric modulator for monoamine transporters, including the dopamine transporter (DAT), vesicular monoamine transporter (VMAT-2), and norepinephrine transporter. While this work has shed light on how Tat impacts the function …

Addressing A Crisis In Nursing Practice: Exploring The Impact Of Multimedia Case-Based Learning On The Clinical Judgment Of Undergraduate Nursing Students, Macy Jenette Bennett

Theses and Dissertations

Clinical judgment is a priority nursing skill to ensure the delivery of safe and effective nursing care. New graduate nurses and nursing students lack the clinical judgment skills that are necessary for entry-level nursing practice. Nurse educators must therefore implement teaching strategies that facilitate clinical judgment. This study evaluated the clinical judgment of undergraduate nursing students after the implementation of multimedia case studies related to the concept of perfusion. Two research questions guided this study: (a) in what ways do undergraduate nursing students demonstrate clinical judgment after completing a series of perfusion-related multimedia case studies and (b) to what extent …

A major and irreversible complication of diabetes is diabetic peripheral neuropathy (DPN), which can lead to significant disability and decreased quality of life. Prior work demonstrates the peptide hormone Angiotensin II (Ang II) is released locally in neuropathy and drives inflammation and impaired endoneurial blood flow. Therefore, we proposed that by utilizing a local thermoresponsive hydrogel injection, we could deliver inhibitors of angiotensin-converting enzyme (ACE) to suppress Ang II production and reduce nerve dysfunction in DPN through local drug release. The ACE inhibitor captopril was encapsulated into a micelle, which was then embedded into a reversibly thermoresponsive pluronics-based hydrogel matrix. …

Chronic itch often clinically coexists with anxiety symptoms, creating a vicious cycle of itch-anxiety comorbidities that are difficult to treat. However, the neuronal circuit mechanisms underlying the comorbidity of anxiety in chronic itch remain elusive. Here, we report anxiety-like behaviors in mouse models of chronic itch and identify γ-aminobutyric acid-releasing (GABAergic) neurons in the lateral septum (LS) as the key player in chronic itch-induced anxiety. In addition, chronic itch is accompanied with enhanced activity and synaptic plasticity of excitatory projections from the thalamic nucleus reuniens (Re) onto LS GABAergic neurons. Selective chemogenetic inhibition of the Re → LS circuit notably …
