Background: Relapsed medulloblastoma remains a significant therapeutic challenge as it is near universally fatal. The tumor microenvironment of medulloblastoma plays a critical role in tumor progression, influencing tumor growth, immune evasion, and therapeutic resistance. We hypothesized that defining tumor-immune interactions in diagnostic and relapsed medulloblastoma may uncover mechanisms of immune evasion and identify novel therapeutic targets.

Methods: We analyzed paired primary and recurrent RNA-sequencing data from 140 medulloblastoma patients to profile immune cell composition and validate spatial relationships within the TME. To identify key tumor-immune interactions, we developed a novel algorithm to detect receptor-ligand pairs using single-cell RNA-sequencing data. These …

Pattern Dynamics And Stochasticity Of Brain Rhythms And Spike Trains In A Tauopathy Mouse Model Of Alzheimer’S Disease, Clarissa M. Hoffman

Dissertations and Theses (Open Access)

Systems neuroscience posits that every aspect of perceived physical reality, every aspect of animal and human behavior, and every cognitive phenomenon emerges from patterns of neuronal activity. While most researchers embrace this idea, there are major difficulties in describing and analyzing these complex neuronal dynamics—spike flows produced by cells ensembles, synchronized extracellular field oscillations, and other patterns—which limits our understanding of how the activity of individual neurons and the whole-animal cognition and behavior might be connected. In particular, we lack the approaches and even the semantics for connecting the individual cell outputs and the integrated results of their activity. Current …

Technical Development, Optimization, And Clinical Implementation Of Quantitative Magnetic Resonance Imaging Methods For Radiation Oncology, Lucas Mccullum

Dissertations and Theses (Open Access)

Magnetic resonance imaging (MRI) has gradually grown more important in the field of radiation oncology. This paradigm shift has grown from initial experiments with MRI of cancerous lesions in the early 1970s, to the integration of MRI images for radiation therapy treatment planning (i.e., MRI-Simulation) in the early 1980s, to the combined MRI linear accelerator (MR-Linac) becoming commercially available in 2018 which can simultaneously image a tumor and treat it with radiation. However, due to its novelty in radiation oncology, its full potential for the integration of quantitative MRI-based biomarkers has yet to be fully realized.

Therefore, this dissertation will …

Optimized Ultrasound Imaging Of Phase-Change Nanodroplets, Charles R Dyall, Dmitry Nevozhay, Andy Liu, Trevor M Mitcham, George J Lu, Konstantin V Sokolov, Richard R Bouchard

Faculty, Staff and Student Publications

Phase-change nanodroplets (PCNDs) continue to generate significant research interest due to their potential to extravasate into tissue, to be targeted for molecular imaging and drug delivery, and to undergo an induced phase-change to "activated" microbubbles (MBs) for ultrasound (US) imaging. To accurately quantify molecular markers, however, one assumes a consistent proportion of PCNDs in a region of interest (ROI) are stably activated and imaged. Herein we present a framework for developing a diagnostic sequence that is optimized for PCND activation uniformity, contrast, and acquisition time. To develop this framework, activation was examined at three scales of increasing complexity: single, adjacent, …

Faculty, Staff and Student Publications

Purpose: Radiation therapy (RT) has emerged as an effective local therapy option for patients with unresectable hepatocellular carcinoma (HCC) and is associated with improved overall survival (OS). However, some patients still have poor outcomes after RT, and biomarkers are needed to stratify prognostic groups. High circulating growth hormone (GH) levels promote HCC proliferation and survival and are associated with aggressive disease. In this study, we evaluated whether pretreatment GH levels are associated with OS and progression-free survival (PFS) in patients who underwent RT for unresectable HCC.

Methods and materials: Patients undergoing RT for HCC during 2017-2023 were identified from a …

Methods: We collected chronic neural data from nine patients with severe obsessive-compulsive disorder who received ventral capsule/ventral striatum DBS treatment between May 2023 and August 2024. We included patients implanted …

Cardiovascular Disease And Dyslipidemia In Pediatric Type 1 Diabetes, Grace K Kim, Preneet Cheema Brar, Nidhi Bansal

Faculty, Staff and Students Publications

Purpose of review

Despite advances in type 1 diabetes (T1D) management, mortality is still increased, with cardiovascular disease (CVD) as the leading cause. Dyslipidemia is a highly prevalent modifiable CVD risk factor. We reviewed the existing literature on CVD mortality in T1D to highlight CVD risk in pediatric patients with T1D.

Recent findings

Pathophysiology of T1D and premature CVD risk is still not fully understood. Dyslipidemia remains a highly prevalent and undertreated CV risk factor in T1D. Statins have been shown to be safe and effective to improve CVD risk in adults with T1D, and in children with familial hypercholesterolemia, …

First, Do No Trend: Aligning Parenteral Lipid Therapy With Physiology And Evidence In Neonates, Parvesh Mohan Garg, Srinivas Bolisetty, Camilia R Martin, Muralidhar H Premkumar

Faculty, Staff and Students Publications

Lipid injectable emulsions (ILE) are essential components of parenteral nutrition in neonatal intensive care units. Over the past two decades, the expanded availability of ILE has led to rapid changes in clinical practice, largely driven by concerns about intestinal failure–associated liver disease. Despite these evolving trends, the evidence supporting one ILE over another remains limited and nuanced. Importantly, no currently available ILE replicates the intrauterine supply of critical long-chain polyunsaturated fatty acids, particularly arachidonic acid and docosahexaenoic acid, both of which decline postnatally regardless of emulsion type. Neonates requiring ILE represent a heterogeneous population of preterm and term infants, with …
