Hydrodynamic cavitation-assisted starch modification: A review of the structural and physiochemical changes induced on starch granules

Food Chemistry Advances
Starch is widely used in food and non-food industries, but conventional modification processes are energy demanding and often rely on chemicals. Hydrodynamic cavitation has recently gained attention as a scalable, energy-efficient, and clean-label ...

A Supramolecular Thermal Switch for Precision Pyroptosis via Host−Guest Recognition and Electrostatic Interactions

Advanced Science, EarlyView.
A supramolecular pyroptotic thermal switch encapsulates I3− within β‐cyclodextrin (β‐CD) and undergoes CaCO3 mineralization. Upon lysosomal acidification, CaCO3 is degraded, releasing Ca2+ and I3−. Concurrently, BODIPY activation converts I3− into I2, inducing oxidative stress and Ca2+ overload, which together trigger caspase‐3/GSDME‐mediated ...

Spatiotemporally Ultrasound‐Controlled Nanoparticles Reprogramming Immunostimulatory Antigen‐Presenting Cancer‐Associated Fibroblasts to Enhance Cancer Immunotherapy

Advanced Science, EarlyView.
We developed an ultrasound‐controlled biomimetic nanoplatform, mRNA/V@M NPs, to co‐deliver CD74 mRNA and V‐9302 for fibrotic TNBC therapy. CD74 mRNA reprograms myCAFs into antigen‐presenting apCAF cells through the CD74‐MHC II pathway, while V‐9302 induces ICD and activates MHC I‐CD8+ T cell immunity.

Evaluation of the effect of pressure conditions on the aggressive intensity of hydrodynamic cavitation produced by a Venturi tube

Nihon Kikai Gakkai ronbunshu, 2017
For hydrodynamic cavitation produced by a Venturi tube, cavitation bubble is collapsed at downstream of a nozzle and its intensity is influenced by upstream pressure and downstream pressure.

Sonoselective Transfection of Glioma Endothelium

Advanced Science, EarlyView.
Delivering non‐viral, gene‐bearing nanoparticles with thiol‐decorated surfaces to gliomas with focused ultrasound yields transfection tropism for endothelial cells. From this platform, “sonoselective” transfection of glioma endothelium is achieved via incorporation of an endothelial cell‐specific promoter.
