Different behavior of electrosurgical currents between air and saline immersion therapeutic endoscopy

open access: yesScientific Reports
Impedance and voltage of monopolar currents are directly related. By replacing air with saline solution, a change in behavior of these currents are achieved in endoscopy, resulting in a desired coagulation effect.

Direct Extracellular Matrix Modulation Attenuates Intestinal Fibrosis via a Fibronectin‐Targeted Approach

open access: yesAdvanced Science, EarlyView.
Fibronectin regulates the extracellular matrix (ECM)–myofibroblast cycle through three key steps: (1) its secretion and assembly by myofibroblasts (inhibited by pUR4); (2) collagen deposition along its scaffold (inhibited by R1R2); and (3) integrin α5β1‐mediated mechanotransduction (inhibited by ATN161).

Colorectal Cancer Cell's Weapon: RNF32 Engages SPP1+ Macrophages to Foster Liver Metastasis, Targeted by Indole‐3‐Acetic Acid

open access: yesAdvanced Science, EarlyView.
Cytoplasmic RNF32 fuels CRC liver metastasis by degrading GSK3β, which stabilizes β‐catenin and activates Wnt/EMT. Moreover, RNF32 rewires the metastatic niche: it depletes CD8+/CD4+ T and NK cells while recruiting SPP1+ macrophages (which boost tumor stemness via CD44), fibroblasts, and immunosuppressive monocytes to aid colonization.

Intelligent Soft Opto‐Magnetic Robot for Minimally Invasive Interventional Therapy

open access: yesAdvanced Science, EarlyView.
An intelligent soft opto‐magnetic (iSOM) robot is developed that integrates remote magnetic actuation, skin‐mimic tactile perception, and photothermal ablation in a near‐millimeter‐scale design. It enables precise intraluminal navigation and localized ablation while providing real‐time optical feedback to support safe and accurate minimally invasive ...

STING Agonist‐Modified Tumor Targeting Photosensitizer Remodels Cancer‐Associated Fibroblasts to Potentiate Photoimmunotherapy in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
This carrier‐free, esterase‐responsive nanoaggregate integrates a mitochondria‐targeting photosensitizer with a non‐nucleotide STING agonist to achieve localized photoactivation and immune reprogramming. ICyM2 remodels tumor stroma, induces potent immunogenic cell death, and triggers intratumoral STING activation, collectively revitalizing the ...
