Bio‐Inspired Micro‐Fin‐Assisted Multi‐Modal Vascular Intervention

open access: yesAdvanced Science, EarlyView.
A magnetic guidewire with a micro‐fin–integrated tip is introduced for multimodal cardiovascular navigation. The micro‐fins exploit fluid drag to augment magnetic torque, enabling bifurcation traversal at 15 mT, tolerating 45° misalignment, bidirectional crawling, and buckle self‐correction.

The Pivotal Role of GR‐CAR Pathway in Fetal Programming of Hepatic Cytochrome P450 3A Alteration in Adulthood

open access: yesAdvanced Science, EarlyView.
Prenatal dexamethasone exposure (PDE) persistently upregulates hepatic CYP3A1/CYP2B1 in offspring via glucocorticoid receptor (GR) activation. In vivo and in vitro studies show GR promotes P300/CBP binding to the constitutive androstane receptor (CAR) promoter, sustaining histone acetylation (H3K9/K27ac) and enhancing CYP expression. The GR–CAR pathway

Alternative Pathway for Methyl Supply through the Coupling of SHMT1 and PEMT to Maintain Astrocytic Homeostasis in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
In Parkinson's disease, SHMT1 downregulation disrupts its interaction with PEMT in astrocytes, reducing SAM levels. This leads to H3K4me1 hypomethylation and decreased Slc1a2/Glul expression, ultimately exacerbating neuroexcitotoxicity and dopaminergic neuron loss.

Arbitrary 3D Organic Mixed Ionic‐Electronic Conductor Architectures via Self‐Fusion of PEDOT:PSS Microfibers

open access: yesAdvanced Science, EarlyView.
A general fabricating strategy for arbitrary 3D organic mixed ionic‐electronic conductor architectures is reported using PEDOT:PSS microfiber building blocks. A water‐assisted self‐fusion process is successfully developed in which adhesion can be modulated as reversible (PSS‐rich) or irreversible (PEDOT‐rich) self‐fusion depending on the post‐treatment

Curved Bistable Origami‐Inspired Flexible Transcatheter Mitral Valve Clamping

open access: yesAdvanced Science, EarlyView.
A lightweight bistable curved origami dilator combines reversible deformation and high stability, offering a promising solution for minimally invasive mitral valve repair. Abstract Curved origami exhibits remarkable potential for minimally invasive medical applications owing to its unique geometric programmability and mechanical tunability. Building on
