The cerebellar ventricular zone (VZ) is the primary source of progenitors that generate cerebellar GABAergic neurons, including Purkinje cells (PCs) and interneurons (INs). This study provides detailed characterization of human cerebellar GABAergic neurogenesis using transcriptomic and histopathological analyses and reveals conserved and unique features compared to rodents. We show that the sequential progression of neurogenesis is conserved and occurs before 8 postconception weeks. Notably, PC differentiation occurs in the outer subventricular zone (SVZ), a region absent in the mouse cerebellum. Human PCs are generated during a compact two-week period before the onset of cerebral cortex histogenesis. A subset of human …

The Attitudes And Perspectives Of Laboratory Professionals On The Use Of Machine Learning Combined With Maldi For Viral Identification: A Qualitative Study, Grace Johnson

Honors Projects

The use of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) with machine learning (ML) has been proposed by numerous studies as a novel approach for viral identification.

Task Demands Influence Search Strategy Selection In Otoconia-Deficient Mice, Ryan M. Yoder, Lucas C. Carstensen, Keshav Jagannathan

Psychology

Introduction: The vestibular system plays a crucial role in visual and non-visual navigation. Our recent study found that signals from the otolith organs are necessary for mice’s use of distal visual cues to guide navigation to an invisible goal. Somewhat surprisingly, however, performance was not significantly impaired on some spatial tasks (e.g., Barnes maze reference memory task), questioning the role of otolith signals in visual navigation.

Methods: We report the results of several additional tests of reference memory performance and search strategy use on two versions of the Barnes maze, in an attempt to establish further understanding of the otolithic …

Glioblastoma (GBM) is an aggressive primary brain cancer with few effective therapies. Stereotactic needle biopsies are routinely used for diagnosis; however, the feasibility and utility of investigative biopsies to monitor treatment response remains ill-defined. Here, we demonstrate the depth of data generation possible from routine stereotactic needle core biopsies and perform highly resolved multi-omics analyses, including single-cell RNA sequencing, spatial transcriptomics, metabolomics, proteomics, phosphoproteomics, T-cell clonotype analysis, and MHC Class I immunopeptidomics on standard biopsy tissue obtained intra-operatively. We also examine biopsies taken from different locations and provide a framework for measuring spatial and genomic heterogeneity. Finally, we investigate the …

The Potential Of Brain Organoids In Addressing The Heterogeneity Of Synucleinopathies, Xiao-Jun Diao, Claudio Soto, Fei Wang, Yu Wang, Yun-Cheng Wu, Abhisek Mukherjee

Faculty, Staff and Student Publications

Synucleinopathies are a group of diseases characterized by neuronal and glial accumulation of α-synuclein (aSyn) linked with different clinical presentations, including Parkinson's disease (PD), Parkinson's disease with dementia (PDD), Dementia with Lewy Bodies (DLB) and Multiple system atrophy (MSA). Interestingly, the structure of the aSyn aggregates can vary across different synucleinopathies. Currently, it is unclear how the aSyn protein can aggregate into diverse structures and affect distinct cell types and various brain regions, leading to different clinical symptoms. Recent advances in induced pluripotent stem cells (iPSCs)-based brain organoids (BOs) technology provide an unprecedented opportunity to define the etiology of synucleinopathies …

Evaluation Of Wound Dehiscence Rate Between Total Ankle Replacement (Tar) And Ankle Arthrodesis (Aa): A Systematic Review And Meta-Analysis, Asad Mustafa, Sarah Weisbrodt, Naohiro Shibuya

School of Podiatric Medicine - Student Research

Introduction

Total ankle replacement (TAR) and ankle arthrodesis (AA) are surgical interventions used for patients with degenerative ankle arthritis. Historically, AA has been the standard treatment for ankle arthritis; however, in recent years, TAR has become just as popular, if not more so. The TARVA study, a randomized controlled trial examining the outcomes of each procedure for a population with end-stage osteoarthritis, reports similar results between the two procedures, except that TAR may have a higher incidence of wound dehiscence. TAR typically requires a larger incision than AA, which may influence patient selection for the procedure. However, data from the …

Mitochondrial Dysfunction And Parkinson's Disease: A Critical Link, Anika J. Millar

Senior Honors Theses

Parkinson’s disease is a neurodegenerative disorder, caused by the damage to and death of dopamine-releasing neurons in the brain. The substantia nigra is a major region housing dopaminergic neurons and plays a critical role in motor and cognitive function. When these neurons are compromised, dopamine levels decline, leading to the development of motor and cognitive dysfunction. Current treatments include dopamine precursors, which help to replace dopamine and relieve motor symptoms. However, while there is symptomatic treatment for Parkinson’s disease, there are no preventative therapies or cures. A potential link between mitochondrial dysfunction and Parkinson’s disease has prompted further research. Investigating …

Historical Perspectives On Bloodletting In The Management Of Asthma In Children And Adults, Joudeh B. Freij, Bishara J. Freij

Conference Presentation Abstracts

Background: Current asthma management consists of a combination of drugs with different mechanisms of action. Ancient asthma care, by contrast, focused on loosening the humours using remedies such as drinking animal blood, eating rabbit fat and fox lungs, inhaling or consuming certain herbs and plants, bloodletting (including wet cupping), diet (eating raisins, dried figs, vegetables, barley, capers, bread, cake), steaming, baths, wet compresses, and moderate helpings of wine with dinner. Bloodletting was believed to purge the body of noxious humours that caused human disease and thereby reduce inflammation. Here we address the use of bloodletting in asthma management over the …

Patients with high-grade serous ovarian carcinoma (HGSC) are usually diagnosed with advanced-stage disease, and the tumors often have immunosuppressive characteristics. Together, these factors are important for disease progression, drug resistance, and mortality. In this study, we used a combination of single-cell sequencing and spatial transcriptomics to identify the molecular mechanisms that lead to immunosuppression in HGSC. Primary tumors consistently showed a more active immune microenvironment than did omental tumors. In addition, we found that untreated primary tumors were mostly populated by dysfunctional CD4 and CD8 T cells in later stages of differentiation; this, in turn, was correlated with expression changes …
