Tracking Focal Adhesion Turnover: A Novel Reporter For Fa-Phagy Flux, Kuizhi Qu, Mengjun Dai, Ying Jiang, Sophie Liu, John P Hagan, Zhen Xu

Faculty, Staff and Student Publications

Focal adhesions (FAs) are critical multi-protein complexes regulating cell adhesion, migration, and survival, and their dysregulation contributes to cancer metastasis and vascular diseases. Despite extensive research on FA formation, little is known about FA turnover, particularly its regulation by autophagy. This study introduces a novel tandem fluorescence reporter capable of tracking the entire FA-phagy flux, from autophagosome formation to lysosomal degradation. The reporter, based on a red–green fluorescence system with a lysosome-specific cleavage site, integrates seamlessly into endogenous focal adhesion complexes, demonstrating sensitivity and specificity to autophagy stimuli. Validated in multiple cell lines, the tool revealed dynamic FA-phagy responses to …

Staff Education In Standardizing A Nurse-Led Fall Prevention Bundle To Reduce Inpatient Falls In Teleneurology Units, Tiffany Scott

Walden Dissertations and Doctoral Studies

Due to complex neurological deficits that raise the risk of falls, falls among persons admitted to inpatient tele-neurology units represent a substantial and continuous problem in nursing practice. A preliminary evaluation conducted at the project site revealed inconsistent fall prevention procedures, inconsistent use of risk assessments, and a lack of a standardized, evidence based strategy to lower fall risk in this especially susceptible group. A practice focused investigation into whether the adoption of a standardized, nurse led fall prevention bundle would improve staff adherence to fall prevention protocols and lower the incidence of inpatient falls over a six month period …

Heterogeneity In The Association Of Genetic Risk For Ra And Resultant Ra Phenotypes, Thomas R Riley, Iris Lee, Et Al.

2020-Current year OA Pubs

OBJECTIVES: The impact of the genetic risk for RA on resultant disease phenotype in RA is incompletely understood. Using individual genetic variants associated with RA and a polygenic score (PGS), we hypothesized that those with higher genetic risk for RA would demonstrate a more severe disease course.

METHODS: We genotyped participants from the Veterans Affairs RA registry (VARA), a prospective cohort of RA. We evaluated associations between PTPN22 R620W genotype, HLA-DRB1 shared epitope (SE; 0, 1, or 2 copies of a high-risk HLA allele), and a non-HLA PGS with RA disease activity scores and disease characteristics using linear and logistic …

Foundation models have emerged as powerful feature extractors in computational pathology. However, they typically omit mechanisms for leveraging the global spatial structure of tissues and the local contextual relationships among diagnostically relevant regions-key elements for understanding the tumor microenvironment. Multiple instance learning (MIL) remains an essential next step following the foundation model, designing a framework to aggregate patch-level features into slide-level predictions. We present EAGLE-Net, a structure-preserving, attention-guided MIL architecture designed to augment prediction and interpretability. EAGLE-Net integrates multi-scale absolute spatial encoding to capture global tissue architecture, a top-K neighborhood-aware loss to focus attention on local microenvironments, and background suppression …

Drug repurposing is the process of reusing existing pharmaceuticals for novel clinical purposes, which offers advantages such as streamlined clinical trial access and reduced drug development costs. Clarithromycin (CAM), a member of the macrolide antibiotics family, is a promising candidate for repurposing in cancer therapy due to its known preclinical and clinical immunomodulatory and anticancer properties. In the current study, we investigated whether CAM could be repurposed as a preventive treatment for KRAS-mutant lung cancer, a subtype of lung adenocarcinoma that is strongly associated with heavy smoking. CCSPCre; LSL-KrasG12D mice at an early stage of tumor development were treated with …

Radiation therapy is integral to the treatment regimens of over 50% of cancer patients. However, it is not biologically targeted to just the tumor, leading to adverse effects in peritumoral normal tissue. Selective uptake of gold nanoparticles (AuNPs) by tumors realizes tumor-specific radiosensitization via increased secondary electron release from high atomic number gold atoms. Here, we review AuNP-mediated radiosensitization and outline strategies to optimize tumor-targeted AuNP delivery. Modifying the physicochemical characteristics of AuNPs, including size, shape, charge, and surface chemistry, can increase their ability to evade the reticuloendothelial system (RES) and penetrate the dense tumor stromal architecture, thereby promoting tumor …

Faculty, Staff and Students Publications

Millions of children worldwide are affected by severe rare Mendelian disorders, yet exome and genome sequencing still fail to provide a definitive molecular diagnosis for a large fraction of patients, prolonging the diagnostic odyssey. Bridging this gap increasingly requires transitioning from DNA-only interpretation to multi-modal diagnostic reasoning that combines genomic data, transcriptomic sequencing (RNA-seq), and phenotype information; however, computational frameworks that coherently integrate these signals remain limited. Here we present RareCollab, an agentic diagnostic framework that pairs a stable quantitative Diagnostic Engine with Large Language Model (LLM)-based specialist modules that produce high-resolution, interpretable assessments from transcriptomic signals, phenotypes, variant databases, …

Two Faces Of Mitral Stenosis: Uncovering Structural And Hemodynamic Signatures Of Rheumatic And Mitral Annular Calcification-Induced Disease, Mohammad S. Hashemi, Peter Abdelmaseeh, Atif Nehvi, Gregg S. Pressman, Arash Kheradvar

Einstein Health Papers

BACKGROUND: Mitral annular calcification (MAC) is common and associated with increased cardiovascular risk and, when severe, mitral stenosis (MS). MAC-related MS differs anatomically and hemodynamically from rheumatic MS (RMS), challenging standard diagnostic methods. This study compares structural and flow characteristics, including  kinetic energy losses, across MAC-related MS, RMS, and normal mitral valves, and evaluates the applicability of conventional diagnostic metrics in MAC.

METHODS: Three-dimensional transesophageal echocardiographic data sets from 70 patients (22 normal mitral valves, 26 RMS valves, 22 MAC valves) were used to obtain linear, area, and volumetric measurements for valve comparison. Representative valves from each group were converted …

Biologically-Inspired Multiscale Neuromorphic Architecture, Christian O'Reilly, Ramtin Zand

Publications

This white paper proposes a biologically-inspired multiscale neuromorphic architecture that bridges key gaps between artificial neural networks (ANNs), spiking neural networks (SNNs), and biological neural networks (BNNs). While SNNs offer promising energy efficiency, their broader adoption remains limited by suboptimal performance and the need for novel learning paradigms. To address these challenges, the proposed framework integrates structural and functional principles observed in the brain, including hierarchical organization, sparse and modular connectivity, predictive coding, and diverse neuronal dynamics.

The architecture operates across micro-, meso-, and macro-scales, incorporating neuron-level diversity (e.g., excitatory/inhibitory and principal/support cells), canonical microcircuits (CMCs), and large-scale hierarchical organization. …

Faculty, Staff and Students Publications

PETG (Polyethylene Terephthalate Glycol)–Carbon Fiber composites fabricated using fused deposition modeling are emerging as promising alternatives for lightweight UAV structures; however, their performance is strongly influenced by internal infill architecture and structural design. From an initial set of 21 infill patterns, five mechanically efficient patterns (Tri-Hexagon, Triangle, Support Cubic, Rectilinear, and Quarter Cubic) were shortlisted and evaluated through tensile, wear, impact, and hardness tests. Rectilinear infill exhibited the highest tensile strength (35 N/mm2) and superior wear resistance under loads up to 30 N, while Quarter Cubic showed comparable tensile performance (34 N/mm2). Support Cubic infill demonstrated the highest impact energy …

Lysine Demethylase 4a (Kdm4a) Maintains Basal Body Architecture And Protects Against Ciliary Destabilization, Xiaoli Wang, Yuya Nakatani, Sofia Vargas-Hernandez, Sung Y Jung, Menuka Karki, Cheryl Walker, Anna-Karin Gustavsson, Ruhee Dere

Faculty, Staff and Students Publications

Primary cilia are sensory organelles essential for signaling and defects in formation, maintenance or structure underlie diverse ciliopathies. Here, we identify lysine demethylase 4A (KDM4A) as a previously unrecognized mediator of ciliogenesis. Using genetic depletion and pharmacologic inhibition, we show that KDM4A is required for cilia assembly and maintenance. Super-resolution imaging reveals KDM4A localization at the basal body, where it distinctively wraps around the centrioles. We uncover a direct interaction between KDM4A and Rootletin (CROCC), a structural protein mediating centriole cohesion, and demonstrate that KDM4A loss increases inter-centriolar distances, implicating basal body architecture in ciliary failure. Together, these findings define …

Alzheimer's disease (AD) is characterized by the accumulation of extracellular aggregated amyloid beta, resulting from impaired waste clearance. We recently identified new cerebrospinal fluid (CSF) efflux structures termed arachnoid cuff exit (ACE) points and speculated that these may be impacted in AD, leading to impaired waste clearance function. Using 5XFAD mice, we found progressive amyloidosis of bridging veins at ACE points. Indeed, in 5XFAD mice, there is impaired CSF efflux to the dura mater, impaired CSF flow along bridging veins, and impaired blood flow through bridging veins. These observations suggest that ACE point amyloidosis plays a role in waste clearance …

Taurine Supplementation And Human Heat Tolerance: Mechanisms, Evidence, And Integration With Heat Acclimation, Cooling, And Hydration, Siavash Naddafha, Jeffrey R. Stout, Cassandra Evans

Research outputs 2022 to 2026

Heat exposure during strenuous exercise increases core temperature and cardiovascular strain, impairing performance and elevating the risk of heat illness. Standard countermeasures include heat acclimation, cooling, and hydration/electrolyte planning. Taurine is a sulfur-containing amino acid present in excitable tissues and widely used as an oral supplement; emerging human trials suggest it can augment thermoregulation, primarily by enhancing eccrine sweating and evaporative heat loss. This narrative review synthesizes mechanistic and applied evidence on taurine during exercise in hot environments and evaluates potential interactions with acclimation, cooling strategies (pre- and per-cooling), and hydration practices. Across a small number of randomized, mostly double-blind …
