Age‐Related Lamin B1 Deficiency Activates SLC7A11‐Dependent Disulfidptosis to Impair Osteogenesis via Intercepting Mitochondrial Fission

open access: yesAdvanced Science, EarlyView.
This study reveals that age‐related LMNB1 deficiency in mesenchymal stem cells epigenetically upregulates SLC7A11, triggering actin disulfidptosis and mitochondrial dysfunction. This cascade impairs bone formation in senile osteoporosis. Furthermore, researchers identified the FDA‐approved drug naldemedine as a targeted SLC7A11 inhibitor to reverse ...

Targeted Perturbation of Mitochondrial Energy Metabolism via Thermoelectric Nanoflowers for Enhanced Cuproptosis Echoed With Immunotherapy

open access: yesAdvanced Science, EarlyView.
We fabricated a thermoelectric nanomedicine to disrupt the ATP energy supply for the copper transporter ATP7B, thereby enhancing cuproptosis and achieving synergistic immunotherapy for anti‐tumor purposes. The fabricated TBCT NFs can efficiently disrupt the electron transport chain function via superoxide‐induced NADH oxidation, leading to ATP ...

Unlocking the Full Potential of Jumping Condensation on Microstructured Surfaces

open access: yesAdvanced Science, EarlyView.
Microcone arrays exhibit a spacing‐dependent transition between jumping and non‐jumping condensation. Dense microstructures favor full Cassie droplets, which depart cleanly, while wider spacing favors partial Cassie droplets that retain a localized wet region initiating new nucleation. These findings establish a link between microdroplet morphology and

AKAP1 Protects Retinal Ganglion Cells and Preserves Vision by Improving Mitochondrial and Synaptic Health in Glaucomatous Neurodegeneration

open access: yesAdvanced Science, EarlyView.
Intravitreal AAV2‐mediated AKAP1 restoration enhances mitochondrial fusion and biogenesis, improves bioenergetic capacity, and preserves mitochondrial integrity in glaucomatous RGCs. AKAP1 stabilizes presynaptic structure, maintaining synaptic protein expression, and limiting complement‐associated neuroinflammation.

Engineering Polar Nanoregions in COFs via Controlled Symmetry Breaking Toward Piezocatalysis

open access: yesAngewandte Chemie, EarlyView.
Polar nanoregions (PNRs) are engineered within covalent organic frameworks via asymmetric grafting of highly polar polyfluoroalkyl chains, which enables controlled symmetry breaking. These randomly oriented artificial PNRs dynamically respond to mechanical stimuli and impart relaxation behavior to the COFs (TFB‐TAPT‐FA).

Therapeutic Peptide‐Programmed Liquid‐Crystalline Topology Switching for pH‐Gated Postoperative Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A VDAP‐programmed liquid‐crystalline depot enables pH‐responsive postoperative immunotherapy for triple‐negative breast cancer. VDAP stabilizes a leakage‐resistant HII mesophase through peptide–lipid electrostatic assembly, whereas tumor acidosis unlocks the matrix and promotes graded topology remodeling toward a bicontinuous Im3̄m cubic phase for ...

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron

open access: yesAngewandte Chemie, EarlyView.
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

A Biomimetic PLK1 Nanodelivery System Promotes Migrasome‐Mediated Mitocytosis to Restore Efferocytosis and Functional Recovery After Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
MM‐NPs@PLK1 are formed by encapsulating PLK1 plasmids within CBP5 and coating the nanocomplexes with macrophage membranes. After macrophage‐associated uptake, the NPs@PLK1 enter the cytoplasm and release the PLK1‐encoding plasmid in response to elevated intracellular ROS levels.

Numerical Analysis of Condensation and Frost in Rotary Heat Exchangers

open access: yes, 2014
In this thesis, a three-dimensional mathematical model is developed and implemented using COMSOL Multiphysics - a platform for physics-based modeling and simulation. The numerical model solves a conjugated heat transfer problem for the air stream and heat exchange media with only wheel data and inlet flow properties needed as input.

CircFAM65A/CANX Condensates Sequester FAM134B to Inhibit ER‐phagy and Suppress Hepatocellular Carcinoma Progression

open access: yesAdvanced Science, EarlyView.
The novel circRNA circFAM65A suppresses HCC progression. Mechanistically, circFAM65A drives CANX phase separation, which recruits FAM134B into condensates and blocks its interaction with LC3, thereby inhibiting ER‐phagy and HCC progression. Importantly, targeted circFAM65A delivery represents a potential therapeutic strategy for HCC.
