Sage: Spatially Aware Gene Selection And Dual-View Embedding Fusion For Domain Identification In Spatial Transcriptomics, Yi He, Yunpei Xu, Liqing Ding, Hong-Dong Li, Yaohang Li, Shaokai Wang

Computer Science Faculty Publications

Despite enabling high-resolution mapping of gene expression within tissues, spatial transcriptomics (ST) still faces challenges in accurately segmenting spatial domains due to complex tissue architecture and limitations of current methods. Most approaches rely on local spatial priors, lack gene-level interpretability, and fall short in capturing structure-discriminative genes or long-range functional relationships, limiting their ability to resolve biologically meaningful architectures. We present Spatially Aware Gene selection and dual-view Embedding fusion (SAGE), a unified and reproducible framework for domain identification in spatial transcriptomics that combines topic-driven gene selection with dual-view embedding fusion to address these gaps. SAGE integrates non-negative matrix factorization (NMF)-based …

Dysregulation Of Alternative Splicing Patterns In The Ovaries Of Reproductively Aged Mice, Adnan T. Alsamaraee, Vanessa L. Correll, Julius O. Nyalwidhe, Pavla Brachova, Nehemiah S. Alvarez

Department of Biomedical and Translational Sciences Faculty Publications

Female reproductive aging is characterized by progressive deterioration of ovarian function, yet the molecular mechanisms driving these changes remain incompletely understood. Here, we used long-read direct RNA-sequencing to map transcript isoform changes in mouse ovaries across reproductive age. Comparing young and aged mice after controlled gonadotropin stimulation, we identified widespread alternative splicing changes, including shifts in exon usage, splice site selection, and transcript boundaries. Aged ovaries exhibited increased isoform diversity, favoring distal start and end sites, and a significant rise in exon skipping and intron retention events. Many of these age-biased splicing events altered open reading frames, introduced premature stop …

The Development And Implementation Of A Computational Framework To Simulate Patellofemoral Joint Mechanics, Mahmood Rashedi

Master’s Theses

Anterior knee pain affects approximately 25% of adults and is associated with altered joint mechanics. Patellofemoral joint (PFJ) models vary widely in complexity, with no established gold standard. Musculoskeletal models efficiently estimate joint loading but do not capture tissue-level mechanics, whereas finite element (FE) models provide tissue-level predictions at greater computational cost. This thesis developed a workflow to evaluate relationships between musculoskeletal model-predicted PFJ loads and FE-predicted cartilage mechanics, examined the impact of altered quadriceps activation, and introduced improved computational models.

Marker trajectories and ground reaction forces were collected from four adults (2 male, 2 female) during walking and squatting. …

Morphological Variation Of The Clavicular Rhomboid Fossa: Bilateral Asymmetry, Sexual Dimorphism, And Environmental Influences, Michaela Tucker, Skylar Hall

Williams Honors College, Honors Research Projects

Morphological variation on the clavicle, specifically the rhomboid fossa, may be impacted by age, sex, laterality, and mechanical stress. Occupational stress and loading conditions lead to bone remodeling and adaptation to change, altering the costoclavicular ligament site. A sample of 94 bilateral clavicles from individuals ages 16-40 years was analyzed using computer tomography (CT) and 3-dimensional reconstruction. Clavicles were categorized into five groups: flat, smooth, elevated, depressed, and pitted. Chi-squared analyses were used to test associations between morphology and age, side, and history of strenuous lifting. Significant differences were observed between class and sex for the leftsided clavicle group. Female …

Generating Synthetic Ct From Mri Data, Foysal Ahmed

Depemokimab: A Twice Yearly Anti-Il 5 Biologic For Chronic Rhinosinusitis With Nasal Polyps (Crswnp) - A Narrative Review, Marn Joon Park, Joseph K. Han, Kent K. Lam

Department of Otolaryngology (ENT) Faculty Publications

Depemokimab is a monoclonal antibody that targets interleukin-5 with enhanced binding affinity and an extended terminal elimination half‑life of 6-8 weeks. The unique pharmacodynamic features of depemokimab enable sustained suppression of type 2 inflammation with twice‑yearly subcutaneous dosing. This narrative review provides details of depemokimab's molecular profile, pharmacokinetics, and pharmacodynamics and results regarding the clinical efficacy and safety of depemokimab from recently published Phase 3 clinical trials for the treatment of chronic rhinosinusitis with nasal polyposis (CRSwNP). In 528 severe adult CRSwNP patients (ANCHOR‑1/‑2 trials), depemokimab achieved Δ total endoscopic nasal polyp score by -0.70 (p <  .001) and Δ nasal obstruction verbal response scale by -0.24 (p = .003) at week 52, compared to placebo. Twice‑yearly 100 mg depemokimab provides durable eosinophil suppression and with a safety profile comparable to placebo in Phase 3 trials for CRSwNP. Future work should refine biomarkers and assess comparative cost‑effectiveness and long‑term adherence, safety, and effectiveness.
