Red Blood Cell‐Derived Exosomal miR‐93‐5p Promotes Lung Cancer Progression through PTEN Suppression

open access: yesAdvanced Science, EarlyView.
Red blood cell (RBC)‐derived exosomal miR‐93‐5p is elevated in lung cancer patients and correlates with poor outcomes. Exosomal miR‐93‐5p suppresses PTEN in cancer cells, enhancing proliferation, migration, and invasion. In mouse models, therapeutic inhibition with ASO‐miR‐93 5p reduces tumor growth, highlighting a bidirectional tumor‐RBC‐tumor axis ...

Biodegradable Adhesive Systems for Bio‐Integrated Applications

open access: yesAdvanced Science, EarlyView.
Biodegradable adhesives provide temporary yet reliable adhesion while degrading into safe, non‐toxic by‐products under physiological or environmental conditions. This review summarizes recent developments in physical and chemical adhesion mechanisms—including hydrogen bonding, catechol chemistry, amine‐carboxyl coupling, and emerging diazirine and urea

Spatio-Temporal Deep Learning Models for Tip Force Estimation During Needle Insertion

open access: yes, 2019
Purpose. Precise placement of needles is a challenge in a number of clinical applications such as brachytherapy or biopsy. Forces acting at the needle cause tissue deformation and needle deflection which in turn may lead to misplacement or injury. Hence,

Surface‐Associated Proteins on Extracellular Vesicles Remodel the Tumor Microenvironment by Potentiating TGF‐β Signaling in a Contact‐Dependent Manner

open access: yesAdvanced Science, EarlyView.
Extracellular vesicles (EVs) released from TGF‐β‐activated CAFs are enriched with ECM proteins such as TSG6 and THBS1, which facilitate their binding to recipient cell membranes. This EV–cell interaction promotes the clustering of CD44 and TGF‐β receptors on the target cell surface, thereby potentiating TGF‐β signaling activity. This study highlights a

Piezoelectric needle sensor reveals mechanical heterogeneity in human thyroid tissue lesions. [PDF]

open access: yes, 2019
Palpable thyroid lesions are common, and although mostly benign, lethal malignant nodules do occur and may be difficult to differentiate. Here, we introduce the use of a piezoelectric system called Smart-touch fine needle (or STFN) mounted directly onto ...

Ionic–Bionic Interfaces: Advancing Iontronic Strategies for Bioelectronic Sensing and Therapy

open access: yesAdvanced Science, EarlyView.
Ionic–bionic interfaces for bioelectronics leverage ions as multifunctional mediators that combine mechanical compliance, ionic and electronic functionalities, and therapeutic effects. These systems offer real‐time biosignal transduction, effective wound dressing, responsive drug delivery, and seamless interaction between soft tissues and electronic ...

Microscopic observations of needle and soft-tissue simulant interactions [PDF]

open access: yes, 2011
Currently, physicians have no means of correctly estimating the needle tip location during percutaneous needle insertion. A model of needle-tissue interaction that predicts the needle tip location would assist physicians in pre-operative planning and ...
