Perfusion Bioreactor Culture Incorporating Mechanical Confinement Enhances Mesenchymal Stem Cell Extracellular Vesicle Production and Wound Healing Potential

open access: yesAdvanced Materials Technologies, EarlyView.
Scalable manufacturing challenges and limited potency remain two of the most intransigent issues limiting clinical translation of EV therapeutics. Mechanical cues can induce phenotypic changes and increased vesiculation in EV source cells without the use of extraneous reagents, chemicals, and/or cargo, thereby potentially drastically improving the ...

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 ...

Associations of attitudes towards electronic cigarettes with advertisement exposure and social determinants: a cross sectional study

open access: yesTobacco Induced Diseases, 2017
Introduction The exposure of young adults to electronic cigarette (e-cigarette) advertisements has risen rapidly. E-cigarette ads have been shown to increase short term perceived acceptability of using e-cigarettes in places where traditional cigarettes ...

Receptivity to E-cigarette Marketing, Harm Perceptions, and E-cigarette Use [PDF]

open access: yesAmerican Journal of Health Behavior, 2015
To test whether exposure and receptivity to e-cigarette marketing are associated with recent e-cigarette use among young adults through increased beliefs that e-cigarettes are less harmful than cigarettes.Data were collected from 307 multiethnic 4- and 2-year college students; approximately equal proportions of current, never, and former cigarette ...

Single‐Cell RNA Sequencing of Human Lung Tissues Reveals Metallothionein‐Positive T Cells as a Novel Potential Marker of Susceptibility to Chronic Obstructive Pulmonary Disease

open access: yesAdvanced Science, EarlyView.
Using single‐cell RNA sequencing of lung samples and flow cytometry of peripheral blood, we identified a novel T cell subset with high metallothionein (MT) expression. These MT‐high T cells suppress CD8+ T cell cytotoxicity and are progressively depleted from healthy controls to chronic obstructive pulmonary disease (COPD) patients, positioning them as

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 ...

E-cigarette advertising exposure in e-cigarette naïve adolescents and subsequent e-cigarette use: A longitudinal cohort study [PDF]

open access: yesAddictive Behaviors, 2018
Electronic (E-) cigarettes are one of the most popular tobacco products used by adolescents today. This study examined whether exposure to advertisements in (1) social networking sites (Facebook, Twitter, YouTube, Pinterest/Google Plus), (2) traditional media (television/radio, magazines, billboards), or (3) retail stores (convenience stores, mall ...

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 ...

Electronic cigarette (e-cigarette)

open access: yesJournal of Oncological Sciences, 2016
Electronic cigarette (e-cigarette) is a device developed with an intent to enable smokers to quit smoking and avoid the unhealthful effects of cigarettes. The popularity of e-cigarette has increased rapidly in recent years. The increase in its use during

Integrative Approaches to Treating Cellular Senescence in Kidney Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT Cellular senescence in the kidney plays a crucial role in the progression of acute kidney injury and chronic kidney disease. Therapeutic approaches targeting senescent cells, such as small molecule senolytic and senomorphic drugs, display efficacy in preclinical models.
