The Bidirectional Effects Of Traumatic Brain Injury And Caudal Fin Amputation On Regeneration In Zebrafish (Danio Rerio), Makenna Wiebe Jan 2027

The Bidirectional Effects Of Traumatic Brain Injury And Caudal Fin Amputation On Regeneration In Zebrafish (Danio Rerio), Makenna Wiebe

Theses and Dissertations (Comprehensive)

Traumatic brain injury (TBI) and caudal fin amputation initiate robust regenerative responses in adult zebrafish (Danio rerio), yet whether regenerative activity in one tissue influences repair at a distant site remains unclear. This study investigated the bidirectional effects of concurrent brain and peripheral injury on regeneration and functional recovery. Specifically, we assessed the effects of TBI on caudal fin regeneration, caudal fin amputation on neural stem cell-associated cellular responses, and combined injury on behaviour. Adult zebrafish received no injury, TBI, caudal fin amputation, abdominal puncture, or combined TBI and caudal fin amputation. I assessed caudal fin regeneration morphometrically and evaluated …

Faculty, Staff and Students Publications

Strains of Limosilactobacillus reuteri have been used to prevent or treat various conditions; however, the mechanisms by which they exert beneficial effects are not completely understood. Infant colic is one example in which L. reuteri DSM 17938 reduces clinical symptoms. While the etiology of colic is unknown, abnormal melatonin levels in infants have been suggested as a possible contributor. L. reuteri DSM 17938 has been shown to produce adenosine from AMP via production of the extracellular enzyme 5′ectonucleotidase (5′NT). Adenosine is a potent signaling molecule that impacts several important aspects of host physiology, including the release of melatonin from the …


Is Your Cyst Really A Ganglion Cyst? A Case Report Of Angioleiomyoma Mimicking A Plantar Fascia Cystic Lesion, Christopher Anjorin Ms Dpmc, Joseph Bender Dpm Dec 2026

Is Your Cyst Really A Ganglion Cyst? A Case Report Of Angioleiomyoma Mimicking A Plantar Fascia Cystic Lesion, Christopher Anjorin Ms Dpmc, Joseph Bender Dpm

School of Podiatric Medicine - Student Research

Ganglion cysts are among the most common benign soft tissue masses encountered in podiatric clinical practice, and their diagnosis is often presumed based on location, clinical observation, and transillumination. However, this case highlights a diagnostic idiosyncrasy: a lesion clinically presumed to be a ganglion cyst within the plantar fascia was ultimately identified as an angioleiomyoma following surgical excision and histopathological evaluation. This finding underscores the importance of maintaining a broad differential diagnosis when assessing cystic lesions, particularly those that transilluminate, as benign vascular tumors may closely mimic more common entities in both clinical presentation and imaging. More importantly, what if …

Pediatric obstructive sleep apnea (POSA) is a common childhood disease that often causes aberrant brain development and cognitive deficits. The pathophysiological underpinnings of cognitive impairments in POSA remain unclear. Here, we examined cellular and molecular aspects of pathology in a mouse model of POSA that features learning and memory deficits. We performed single-nucleus RNA-sequencing (snRNA-seq) of the hippocampus to examine gene expression changes in an unbiased and cell type-specific manner. This dataset revealed a striking perturbation of transcriptomes across all brain cell types, particularly within glia and neural stem cells. We validated reduced expression of several differentially expressed genes at …

Individual Host Variation In Single-Cell Responses To Enteroaggregative Escherichia Coli Infection Modeled With Human Colon Organoids, Ling Qiu, Tajhal D Patel, Hannah E Jones, Cristian Coarfa, Anthony W Maresso

Faculty, Staff and Students Publications

Enteroaggregative Escherichia coli (EAEC) is a leading cause of diarrhea worldwide. Interestingly, EAEC disease outcomes vary dramatically among infected individuals, ranging from asymptomatic colonization to acute and chronic diarrhea. While previous research has focused on EAEC virulence factors, emerging evidence suggests that host genetic and cellular background may be equally important in determining disease susceptibility. To understand host-driven disease heterogeneity, we performed single-cell RNA sequencing on human colon organoids (HCOs) derived from three healthy adult donors following EAEC 042 infection. Surprisingly, despite comparable EAEC adherence across donors, we observed striking donor-specific responses to infection at multiple levels. A total of …

No Evidence For Modulation Of The Readiness Potential By Respiratory Phase During Natural Breathing, Lucas Jeay-Bizot, Raniyah Chisti, Uri Maoz, Aaron Schurger Sep 2026

No Evidence For Modulation Of The Readiness Potential By Respiratory Phase During Natural Breathing, Lucas Jeay-Bizot, Raniyah Chisti, Uri Maoz, Aaron Schurger

Psychology Faculty Articles and Research

Respiratory processes are increasingly implicated in shaping neural activity and behavior. Recent studies have reported a coupling between respiratory phase and the cortical readiness potential (RP), suggesting that breathing may modulate the neural processes preceding voluntary action. Here, using electroencephalography recordings in humans, we re-examine this claim using the original dataset and a new independent dataset, as well as in simulated data with no coupling. We show that the reported association arises from a confound: both RP amplitude and respiratory phase are coupled to movement onset. The original analysis does not control for this dependency, leading to a spurious effect …

Estrogen receptor-positive (ER+) breast cancer exhibits a marked propensity for skeletal metastasis; however, the molecular drivers of bone colonization remain incompletely defined. We investigated the tumor suppressor neurofibromin (NF1), a dual repressor for RAS and ER signaling, whose inactivation promotes endocrine therapy (ET) resistance and is associated with inferior relapse-free survival. NF1 copy number loss was detected in 62% of ER+ patients who subsequently developed metastases and was associated with an increased likelihood of bone metastases at initial diagnosis. In mouse xenograft models, NF1-depleted ER+ breast cancer cells demonstrated enhanced dissemination to skeletal sites following surgical resection of primary tumors. …

The majority of breast cancer patients have tumors expressing estrogen receptor α (ER) and receive endocrine therapy. However, around one-third relapse in their disease, predominantly with retained ER expression. Molecular alterations are proposed to be contributors to the resistance mechanisms. Patients with ER-positive, human epidermal growth factor receptor 2 (HER2)-negative primary breast cancer with an ER-positive relapse <  5 years of ongoing endocrine therapy were retrospectively assessed. Extracted DNA was analyzed through panel sequencing, and RNA by microarray, from patients’ primary (n = 58), and paired relapse tumors (n = 54), and tumor-free lymph nodes (DNA germline controls, n = 62). Several single-nucleotide variations and copy number variations showed nominal exploratory associations with worse overall survival. Copy number correlations with intrinsic subtypes and …

Translational Initiative To Minimize Childhood Hemiparesis After Asymmetrical Perinatal Brain Injury, Susan V. Duff, Emily Garavatti, Terrie Inder

Physical Therapy Faculty Articles and Research

The purpose of this perspective paper is to present a translational approach aimed at identifying the critical periods in brain development during which to provide neuroprotective and neurorestorative strategies, followed by prehensile training, to minimize hemiparesis and foster skill acquisition after asymmetrical perinatal brain injury (APBI). We contend that hemiparesis could be minimized after APBI through a multimodal sequential approach based on timely implementation of evidence-based intervention strategies. If APBI is identified early, neuroprotective techniques can be used in the first 10 days of life to minimize cell death. This can be followed in the next 3 months by the …


Data-Driven Staging Of Neurodegenerative Pathology Related To Alzheimer’S Disease, Thomas Earnest Aug 2026

Data-Driven Staging Of Neurodegenerative Pathology Related To Alzheimer’S Disease, Thomas Earnest

McKelvey School of Engineering Graduate Student Theses & Dissertations

Alzheimer’s Disease (AD), the most common cause of dementia, is a dual proteinopathy exhibiting deposits of extracellular amyloid-beta (Aβ) and intracellular tau in brain tissue. Models which describe the spatial and temporal trajectories of these pathologies have been invaluable for understanding AD and have the potential to support diagnosis, disease monitoring, and treatment development. Disease staging systems, which provide protocols for assessing individual disease severity based on their extent of brain pathology, have been crucial for explaining and diagnosing AD. However, these systems have been primarily informed by post-mortem histological assessments and are not directly applicable to disease assessment in …


Male Osteoporosis: Pathophysiology, Risk Assessment, And Evidence-Based Management, Seli̇n Teki̇n, Alper Gürlek Aug 2026

Male Osteoporosis: Pathophysiology, Risk Assessment, And Evidence-Based Management, Seli̇n Teki̇n, Alper Gürlek

Turkish Journal of Medical Sciences

Osteoporosis in men is a common yet underrecognized condition associated with substantial fracture-related morbidity and excess mortality. Although men generally attain higher peak bone mass than women, age-related changes in bone microarchitecture, progressive cortical bone loss, declining sex steroid bioavailability, and a high prevalence of secondary causes contribute to a significant lifetime fracture risk. Importantly, a large proportion of fragility fractures in men occur at bone mineral density (BMD) values above the osteoporotic threshold, highlighting the limitations of BMD-based diagnosis alone. This review provides a comprehensive overview of the epidemiology, pathophysiology, and clinical characteristics of osteoporosis in men, with particular …

Turkish Journal of Medical Sciences

Background/aim: This study explored the relationship between concerns about weight and body shape and quality of life in bariatric surgery candidates with morbid obesity regarding the onset of the weight problem in childhood, adolescence, or adulthood.

Materials and methods: We included 453 patients who applied to our center for preoperative bariatric surgery assessment between January 2010 and April 2019. We reviewed the sociodemographic information, psychiatric diagnoses, and results of the Body Shape Questionnaire-34, Quality of Life Scale, Beck Depression Inventory, and Beck Anxiety Inventory of all patients.

Results: Concerns about weight and body shape were increased in women (p < 0.001), unemployed patients (p = 0.001), those with a comorbid psychiatric disorder (p < 0.001), and those with childhood- or adolescent-onset of weight problems (r = –0.170; p < 0.001). Concerns about weight and body shape had a relationship with the vitality (r = –0.434), mental health (r = –0.464), social functioning (r = –0.418), pain (r = –0.307), and general health (r = –0.352) subscale scores of quality of life. Physical functioning was higher (p = 0.037) in patients with childhood- or adolescent-onset obesity compared to patients with adult-onset obesity, while mental health was higher (p = 0.001) in the latter group. Individuals with childhood- or adolescent-onset obesity inquired about bariatric surgery options at an earlier age (p < 0.001).
