Spatial Profiling Reveals Distinct Molecular and Immune Evolution of Mouse Lung Adenocarcinoma Precancers with or Without Carcinogen Exposure

open access: yesAdvanced Science, EarlyView.
Tumor evolution in lung adenocarcinoma is shaped by genetic alterations and spatial immune dynamics. By integrating whole‐exome sequencing, imaging mass cytometry, and spatial transcriptomics across two mouse models, this study reveals how mutational burden, immune infiltration, and cell–state interactions evolve during early and late carcinogenesis ...

The impact of cigarette and e-cigarette use history on transition patterns: a longitudinal analysis of the population assessment of tobacco and health (PATH) study, 2013–2015

open access: yesHarm Reduction Journal, 2020
Background Population models have been developed to evaluate the impact of new tobacco products on the overall population. Reliable input parameters such as longitudinal tobacco use transitions are needed to quantify the net population health impact ...

OPTRACE: Optical Imaging–Guided Transplantation and Tracking of Cells in the Mouse Brain

open access: yesAdvanced Science, EarlyView.
OPTRACE establishes an optical, two‐step platform for intracerebral cell therapy. Transparent glass pipettes enable real‐time, image‐guided delivery, while multiplex genetic labeling with two‐photon and bioluminescence readouts supports longitudinal single‐cell tracking and host–graft dynamics.

Electronic cigarette use patterns and reasons for use among smokers recently diagnosed with cancer

open access: yesCancer Medicine, 2018
Many patients with cancer use electronic cigarettes (e‐cigarettes), yet little is known about patterns and reasons for use. Using cross‐sectional baseline data from a randomized controlled trial, we aimed to describe prevalence and correlates of e ...

Macrophage–Derived Ferritin Exacerbates Silica‐Induced Pulmonary Fibrosis via PIK3R2‐Mediated Fibroblast Differentiation

open access: yesAdvanced Science, EarlyView.
This study identifies ferritin as a pivotal mediator of silica‐induced pulmonary fibrosis. Macrophage‐derived ferritin drives fibroblast‐to‐myofibroblast differentiation via the PIK3R2/SMAD pathway, while ferritin knockdown alleviates fibrosis. These findings define ferritin as both a biomarker and pathogenic driver, highlighting ferritin‐PIK3R2 ...

SAGE: Spatially Aware Gene Selection and Dual‐View Embedding Fusion for Domain Identification in Spatial Transcriptomics

open access: yesAdvanced Science, EarlyView.
SAGE is a unified framework for spatial domain identification in spatial transcriptomics that jointly models tissue architecture and gene programs. Topic‐driven gene selection (NMF plus classifier‐based scoring) highlights spatially informative genes, while dual‐view graph embedding fuses local expression and non‐local functional relations.

E-cigarette school policy and staff training: Knowledge and school policy experiences with e-cigarette products among a national sample of US middle and high school staff.

open access: yesPLoS ONE, 2022
BackgroundAs youth e-cigarette use has surged in the last several years, teachers and school administrators have reported challenges addressing student use of emerging e-cigarette products on school property. While federal policy prohibits smoking in U.S.

Decoding Proton‐Coupled Electron Transfer Mechanism of Nicotine for Multi‐Scenario Portable Electrochemical Sensing

open access: yesAdvanced Science, EarlyView.
A key challenge in nicotine electroanalysis is the unresolved complexity of its interface process, which directly determines sensor metrics. Herein, the proton‐coupled electron transfer mechanism of nicotine is decoded for multi‐scenario portable electrochemical sensing.

Structural problems without structural solutions? Youth leaders' perceptions of their community

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract As young people explore and reflect on the conditions of their neighborhoods and communities, they can forge a critical consciousness—merging their perspectives and analysis to direct both individual and collective actions. Photovoice is a methodological tool that allows participants to document their perspectives and analysis and discuss with
