Ms-Gator: Multi-Scale Graph Attention With Topological Reasoning For Segmentation And Classification Of Prostate Cancer Based On Gleason Scores Using Histopathology Images, Sujata Patil, Mahadeva Swamy, Kavitha Sooda, Rajanikanth Vadigepalli, Khalid Nazim Abdul Sattar, Md Rafeeq

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Prostate cancer is one of the prevalent and potentially fatal malignancies, affecting men globally. Accurate segmentation and classification of prostate cancer in histopathology images remain challenging due to complex tissue architecture, staining variability, and high inter-observer differences in manual diagnosis. To address these challenges, this research proposes a Multi-Scale Graph Attention with Topological Reasoning (MS-GATOR) for segmentation and classification of prostate cancer based on Gleason Scores (GS). The MS-GATOR incorporates topological reasoning with hierarchical biological structures by constructing a graph-based representation among three spatial scales such as nuclei, glands, and tissues using Delaunay triangulation to capture both geometric and photometric …

Targeting Oxidative Stress In Cadasil: Case Insights And Therapeutic Approaches, Maria Meshreky, Richard Weinberger, Giana Johnson, Andrew Abraham, Jacob Rosendale

The Journal of Integrated Primary Care

Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is a rare hereditary small-vessel disease caused by NOTCH3 mutations, leading to recurrent ischemic strokes, cognitive decline, and early-onset dementia. Oxidative stress has been implicated in the pathophysiology of small-vessel cerebrovascular disease, but therapeutic strategies targeting oxidative injury remain limited. We present a 40-year-old female with recurrent ischemic strokes involving the right and left middle cerebral arteries, persistent hypercoagulability of unknown etiology, and no identifiable inherited or acquired thrombophilia. Despite well-controlled blood pressure and standard medical management, the patient remains at high risk for cerebrovascular injury. An extensive review of …

Background: Oscillatory shear stress (OSS), resulting from disturbed blood flow, is implicated in atherosclerotic plaque formation by incompletely understood mechanisms. This study aims to elucidate the involvement of death-associated protein kinase (DAPK) 2 in OSS-induced endothelial cell (EC) activation and atherosclerosis.

Methods: Publicly available resources, including genome-wide microarray, RNA sequencing, and single-cell RNA sequencing, were utilized to identify key OSS-sensitive regulatory factors. Techniques such as mass spectrometry, immunoprecipitation, proximity ligation assay, and RNA sequencing were employed to identify pyruvate kinase M2 (PKM2) as the binding protein of DAPK2 and determine the specific site of PKM2 phosphorylation by DAPK2. To assess …

Acute traumatic aortic injury (ATAI) is a rare but life-threatening consequence of blunt trauma that requires prompt diagnosis and accurate imaging assessment. This review presents an imaging-based approach to ATAI, with emphasis on computed tomography angiography (CTA) as the first-line modality for diagnosis, grading, treatment planning, and follow-up. CTA enables the detection of both direct and indirect signs while also allowing for the assessment of lesion severity, extent, and associated findings that may influence management. Familiarity with common mimics and anatomic variants improves diagnostic confidence and helps avoid false positive interpretations. Careful protocol optimization, including multiphasic acquisition, bolus timing, and …

A Tv-Bm3d Iterative Algorithm For Vmat-Ct Reconstruction, Chia-Lung Chien, Beibei Guo, Rui Zhang

Faculty, Staff and Students Publications

Volumetric modulated arc therapy-computed tomography (VMAT-CT), which is the CT reconstructed using the portal images collected during VMAT, can potentially be an effective onsite imaging tool. The goal of this study was to propose an iterative reconstruction algorithm that can further improve the image quality of VMAT-CT and reduce the number of failed reconstructions. An iterative algorithm combining total variation (TV) with block-matching and 3D filtering (BM3D) was proposed, addressing the L1-L2 regularization problem using the split Bregman method. We collected portal images from 67 VMAT cases including 50 phantom and 17 real-patient cases. Both Feldkamp-Davis-Kress (FDK) and TV-BM3D iterative …

Aberrant neurotransmitter signaling and transcriptional dysregulation are hallmarks of gliomagenesis and represent potential therapeutic targets. Monoamine neurotransmitters such as dopamine and serotonin primarily activate GPCRs but can also function epigenetically as histone H3 modifications. Here, we uncover mechanisms of crosstalk between monoamine neurotransmitter signaling, H3 dopaminylation, and RNA polymerase II (Pol2) transcription in diffuse midline glioma (DMG). We find that co-treatment with Pol2-targeting CDK9 inhibitors (CDK9i) and FDA-approved neuropsychiatric drugs, including selective serotonin reuptake inhibitors (SSRIs), synergistically reduces DMG growth. Mechanistically, CDK9i+SSRI treatment alters H3 dopaminylation patterns and represses synaptic and neurodevelopmental gene transcription associated with CDK9i resistance. Further phospho-proteomic …

Cerebellar Oligodendrocytic Α-Synuclein Pathology And Dentate Nucleus Neuronal Hypertrophy In Parkinson’S Disease, Diego Iacono, Hui Peng, John Paul Bouffard, Roger Kurlan

Department of Neurology Faculty Papers

Idiopathic Parkinson's disease (iPD) research has historically prioritized basal ganglia dysfunction and neuronal Lewy body pathology, often overlooking cerebellar and non-neuronal cells contributions. This study investigates cerebellar neuropathology in iPD, specifically focusing on neuronal and non-neuronal cells of the dentate nucleus (DN) and its adjacent white matter (DN-WM). We systematically assessed autopsy-confirmed iPD brains vs. age-matched controls using immunohistochemistry and stereology-based morphometry methods. The study evaluated α-synuclein pathology, other common age-related co-occurring pathologies (β-amyloid, Tau, neuroinflammation), myelin integrity (Luxol-Fast-Blue), and neuronal volumetric changes in the DN of the cerebellum. In iPD brains, we identified intracytoplasmic α-synuclein inclusions within oligodendrocytes across …

Faculty, Staff and Students Publications

Transforming growth factor β (TGFβ) signaling pathways are integral for a plethora of biological processes. SMAD2 and SMAD3 are the principal transcriptional effectors of TGFβ superfamily ligands, yet quantitative, genome-wide mapping of their DNA-associated complexes under physiological contexts has remained limited due to the lack of specific, robust models. Here, we generated two versatile epitope-tagged mouse models in which endogenous SMAD2 and SMAD3 proteins are globally tagged with hemagglutinin (HA) and podoplanin (PA) sequences, respectively, enabling high-fidelity profiling of SMAD2 and SMAD3 binding across tissues. To demonstrate the broad application of our models, we exemplified the usage of our lines …

La Dolce Vita Or The American Way: A Comparative Study Into The Italian And American Healthcare Systems Through An Analysis Of Total Knee Replacements, James (Jim) Mcmurray '26

Honor Scholar Theses

This thesis presents a comparative study of the Italian and the American healthcare systems, using Total Knee Replacements (TKRs) as a standardized metric to evaluate the health policy, financing, and patient outcomes. Despite the United States spending over $10,000 more per capita on healthcare than Italy, American life expectancy is 5 years shorter than Italian life expectancy. Through a mixed-methods analysis of data from the American Joint Replacement Registry (AJRR), the Programma Nazionale Esiti (PNE), the Registri Italiani di ArtoProtesi (RIAP), and the HCUPnet (AHRQ) database, this research identifies multiple disparities throughout the system. Key findings in this thesis include …

Systemic neoadjuvant chemotherapy, often combined with immunotherapy, is the standard of care for early-stage, non-breast cancer susceptibility gene (BRCA)-mutant triple negative breast cancer (TNBC). However, up to 70% of patients retain residual disease after treatment, which is linked to recurrence and mortality within 5 years. To define mechanisms of resistance, we performed single-cell RNA sequencing on orthotopic TNBC patient-derived xenografts during a cycle of treatment with doxorubicin and cyclophosphamide (AC). Clustering identified four tumor epithelial cell populations, with basal cells enriched in residual tumors. These basal cells up-regulated C15ORF48, a paralog of the mitochondrial cytochrome c oxidase associated subunit FA4 …

Baltic Journal of Health and Physical Activity

Background/Objectives: Impulsivity is a key transdiagnostic trait linked to dysregulated reward processing in both behavioral and substance-related addictions, as recognized in DSM-5. Dopaminergic genes, including DRD2, may modulate individual differences in impulsivity, particularly under conditions of increased addiction vulnerability. This study examined whether the DRD2 Exon 8 rs6276 polymorphism predicts impulsivity levels in men with mixed addictive behaviors compared with healthy controls. Methods: A total of 328 males (128 with mixed behavioral and substance addictions and 200 controls) were assessed. Diagnoses were confirmed using the MINI interview, and impulsivity was measured with the Barratt Impulsiveness Scale (BIS-11). Genotyping of …

NANOG overexpression has been reported to reverse aging-associated decline in mesenchymal stem/stromal cell (MSC) function, but the molecular machinery engaged by NANOG in MSCs remains incompletely defined. Here, we applied APEX proximity labeling coupled with quantitative mass spectrometry to define the NANOG proximity interactome (proxeome) in human MSCs. Of 1040 quantified proteins, 828 were significantly enriched in the APEX-NANOG (H2O2 labeling) samples, consistent with a broad NANOG-centered neighborhood rather than a single stoichiometric complex. Enriched proteins encompass RNA-processing pathways (including splicing/RNP factors and selected m6A-related proteins), transcriptional coactivation and elongation control (Mediator and 7SK/P-TEFb regulators), chromatin repression/poising modules (Polycomb and …

Paediatrics and Child Health, East Africa

The prevalence and clinical significance of mixed Plasmodium infections in children with severe Plasmodium falciparum (P. falciparum) malaria are not well characterized. In a cohort of 440 Ugandan children hospitalized with severe malaria who were diagnosed with Plasmodium species via microscopy, nested polymerase chain reaction (nPCR) testing was used to detect P. falciparum, Plasmodium ovale (P. ovale), Plasmodium malariae (P. malariae), and Plasmodium vivax (P. vivax) infections and assess their association with adverse clinical outcomes during hospitalization. Using nPCR testing, the Plasmodium 18S small-subunit ribosomal RNA gene was detected in 440 children. Plasmodium falciparum mono-infection was identified in 329 (74.8%) …


Rearfoot Realignment As A Prophylactic Strategy For Recurrent Lateral Column Ulcers In Diabetic Foot: A Case-Based Hypothesis, Christopher I. Anjorin Ms Dpmc, Ali-Abdul Kareem Dpm Apr 2026

Rearfoot Realignment As A Prophylactic Strategy For Recurrent Lateral Column Ulcers In Diabetic Foot: A Case-Based Hypothesis, Christopher I. Anjorin Ms Dpmc, Ali-Abdul Kareem Dpm

School of Podiatric Medicine - Student Research

Lateral column ulcerations remain a persistent and complex challenge in diabetic foot management. Although procedures such as tailor’s bunionectomy may provide localized pressure relief, they often fail to address the underlying biomechanical contributors, most notably rearfoot deformities such as calcaneal varus or pes cavovarus frequently observed in diabetic patients. These structural abnormalities shift the weight‑bearing axis laterally, increasing ground reaction forces along the fifth metatarsal and predisposing individuals with diabetic peripheral neuropathy and impaired proprioception to recurrent ulceration. This case explores the hypothesis that prophylactic rearfoot realignment may offer superior long‑term outcomes by correcting the mechanical etiology of lateral column …
