A Visible Light‐Responsive Hydrogel to Study the Effect of Dynamic Tissue Stiffness on Cellular Mechanosensing

open access: yesAdvanced Functional Materials, EarlyView.
A visible light‐responsive polyacrylamide‐azobenzene hydrogel enables safe, reversible stiffness control for studying cell mechanobiology without harmful UV exposure. This approach reveals stem cells respond rapidly to mechanical changes, showing altered shape and protein distribution within one hour.

Transmembrane Activation of Catalysis and Protein Refolding in Synthetic Cells by Enzymes and Nanozymes

open access: yesAdvanced Functional Materials, EarlyView.
Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

“Therapies Through Gut:” Targeted Drug Delivery for Non‐Gastrointestinal Diseases by Oral Administration

open access: yesAdvanced Healthcare Materials, EarlyView.
Schematic illustration of the mechanism of targeted delivery of nanoparticles including 1) paracellular, 2) endolysosomal escape, 3) receptor mediated endocytosis, and 4) M cell mediated transport for non‐GI diseases by oral administration such as atherosclerosis, cancer, diabetes, and brain diseases. Abstract Oral drug delivery is a promising approach

Fabrication of a Lipopolysaccharide‐Targeting Peptide‐Based Colloid for Alleviating Carbapenem‐Resistant Enterobacteriaceae‐Induced Cutaneous Infection

open access: yesAdvanced Healthcare Materials, EarlyView.
In this study, a novel cationic peptide, IW is designed and synthesized, with a tandem‐repeat sequence demonstrating potent activities against a broad spectrum of clinically relevant Carbapenem‐resistant Enterobacteriaceae in both the planktonic and biofilm states. IW is then formulated with P407 to form IW‐P407 colloids.

Balanced Reciprocal Translocation t(X;1) in a Girl with Tall Stature and Primary Amenorrhea

open access: yesIranian Journal of Medical Sciences, 2017
Chromosomal translocations constitute one of the most important, yet uncommon, causes of primary amenorrhea and gonadal dysgenesis. Although X-autosome translocations are frequently associated with streak gonads and clinical features of the Turner ...
