Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

Phytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by

Open Set Recognition and Category Discovery Framework for SAR Target Classification Based on K-Contrast Loss and Deep Clustering

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Synthetic aperture radar automatic target recognition (SAR ATR) has been widely studied in recent years. Most ATR models are designed based on the traditional closed-set assumption.

Multifunctional Nanodiamond Conjugate With a Tumor‐Specific EGFR‐Targeting Peptide and Photoactivated CO Release for Improved Therapeutic Efficacy in Head and Neck Cancers

Small, EarlyView.
A multifunctional nanodiamond conjugate carrying a blue light‐activated carbon monoxide‐releasing molecule and an EGFR‐targeting peptide enables efficient, targeted CO delivery in vitro and in vivo. Upon photoactivation, the particles induce cancer‐specific cytotoxicity and significantly suppress tumor growth and lymph node metastasis in a head and ...

Out-of-Distribution Knowledge Inference-Based Approach for SAR Imagery Open-Set Recognition

Remote Sensing
The efficacy of data-driven automatic target recognition (ATR) algorithms relies on the prior knowledge acquired from the target sample set. However, the lack of knowledge of high-value unknown target samples hinders the practical application of existing

Theranostic π Electron‐Stabilized Polymeric Micelles for PET Imaging‐Guided Drug Delivery to Tumors

Small, EarlyView.
Cancer nanomedicine efficacy is limited by heterogeneous nanoparticle accumulation in tumors. Nuclear imaging offers non‐invasive, patient‐ and lesion‐specific visualization and quantification of nanoparticle uptake. We present a positron emission tomography (PET)‐imageable micelle platform for direct quantification of nanoparticle accumulation and ...

Vine Tendril‐Inspired Cold‐Programmable Shape‐Memory Polymer Composites Using Sugar Beet Pulp

Small, EarlyView.
Vine tendrils inspire a bio‐derived, cold‐programmable shape‐memory polymer composite (SMPC). Magnetically guided sugar beet pulp creates mesoscale heterogeneity within a glassy matrix, producing built‐in mechanical asymmetry for rapid, solvent‐free programming by simple stretching.

Photo‐Activated Merging Cascades in Droplet Swarms Upon Synergistic Solvation of Surfactants

Small, EarlyView.
UV activates the motility of UV‐responsive droplets through a decylammonium/carbamate crystalline layer at the air/water interface. Upon merging with immobilized C12E3 surfactant droplets in the layer, hybrid droplets form which dissolve the layer due to synergistic solvation. In large droplet fields, this non‐linear behavior drives cascading events of

Photo‐Switched Catalytic Amyloids

Small, EarlyView.
Photo‐switched reversible hierarchical assembly of catalytic amyloid fibrils is accomplished by mixing an amphiphilic cross‐ß peptide with a merocyanine photo switch. The peptide monomers, comprising phenylalanine‐lysine repeats, do not self‐assemble in water because of the electrostatic repulsion.
