Multifunctional NIR‐Triggered Nanozyme‐Based Microneedles for Synergistic Eradication of MRSA and Enhanced Wound Healing

Advanced Science, EarlyView.
The novel microneedle patches (MN@CTB) are fabricated by integrating CTB nanozymes into HAMA and PVA solution based on a photo‐crosslinking reaction. The MN@CTB microneedle patches present an excellent photothermal effect and NIR‐stimulated release of NO, which is advantageous for the elimination of MRS.

A Mesoporous Calcium Peroxide Nanocuboid with High Tumor Accumulation Across Biological Barriers for High Efficacy Tumor Therapy

Advanced Science, EarlyView.
The ferroheme (FH) and exceedingly small magnetic iron oxide nanoparticles (IO) loaded mesoporous calcium peroxide nanocuboid (MCPNC) with conjugation of hyaluronic acid (HA) possesses exceptional capability of tumor accumulation, and enhances therapeutic efficacy of tumors based on the mechanism of promoting a positive feedback loop of Fenton reaction

The Iron–Sulfur Cluster of Bacterioferritin‐Associated Ferredoxin (Bfd): a “Biological Fuse” that Prevents Oxidative Damage to Cells?

Angewandte Chemie, EarlyView.
When cellular iron is low, bacterioferritin (Bfr) releases its stored iron through a reductive process dependent on the [2Fe–2S] ferredoxin Bfd. Why accessing stored iron should depend on an iron‐requiring protein when iron is scarce is unclear. Here, we show that the Bfd [2Fe–2S] cluster is sensitive to oxidative stress, suggesting that it may act as ...

Harnessing the Biological Responses Induced by Nanomaterials for Enhanced Cancer Therapy

Aggregate, EarlyView.
Nanomaterial (NM)‐induced toxicity can be strategically repurposed for cancer therapy. This review summarizes the mechanism by which NMs selectively activate specific cellular processes to regulate cell fate independently. We also discussed how NMs‐induced biological responses can be leveraged as therapeutic strategies for cancer treatment.

Supramolecular Probe for Monitoring Lysosomal Ferritinophagy to Facilitate the Early Diagnosis of Parkinson's Disease

Aggregate, EarlyView.
A supramolecular fluorescent probe, TPE‐4B/4Q[7], was designed to target lysosomes. The restriction of intramolecular rotation effect mediated by Q[7] enhances the fluorescence of TPE‐4B/4Q[7], enabling selective detection of Fe3+ with a detection limit of 1.23 × 10⁻⁶ M.

Systemic Mastocytosis in 910 Patients: Prognostic Contribution of the International Consensus Classification in the Context of the Mayo Alliance Prognostic System

American Journal of Hematology, EarlyView.
Overall survival data among 910 Mayo Clinic patients with systemic mastocytosis stratified by the International Consensus Classification (ICC) and the Mayo Alliance Prognostic Scoring System (MAPS). ABSTRACT The current study includes 910 patients with systemic mastocytosis (SM) seen at the Mayo Clinic from 1968 to 2024.
