Mechanisms and Pathophysiological Significance of Insulin Resistance in Offspring With Intrauterine Growth Restriction Mediated by Hepatic GR/miR‐1224 Programming

Advanced Science, EarlyView.
This work found that early‐stage insulin sensitization but late‐stage insulin resistance in prenatal caffeine exposure (PCE)‐ induced intrauterine growth restriction (IUGR) offspring may be related to the hepatic AGEs accumulation via intrauterine GR/miR‐1224 programming by glucocorticoids.

Quantification of Antibiotic Diffusion in Biofilms Using Gold Nanostar Surface‐enhanced Raman Spectroscopy

Advanced Science, EarlyView.
Gold nanostar‐enhanced Raman spectroscopy (SERS) enables real‐time, label‐free tracking of levofloxacin diffusion in intact biofilms. Nanostars embedded 16 µm below the surface detect drug arrival over time, revealing the impact of the biofilm matrix on antibiotic transport. Abstract The increased resistance to antibiotics shown by bacteria in biofilms

CDK4/6 Inhibitor Priming Enhances PD‐1 Blockade via Sellhi Neutrophil‐Induced Stat5a+ Progenitor Exhausted CD8+ T Cell

Advanced Science, EarlyView.
Activated tumor‐intrinsic cyclin D1‐CDK4/6 signaling attenuates lymphocyte infiltration, and consequently, and immunotherapy resistance in HNSCC. It is discovered that brief CDK4/6i priming before anti‐PD‐1 results in enhanced durability of ICB response durability through Stat5a+ progenitor exhausted CD8+ T cells induced by IL15‐secreted Sell(hi ...

A Minimally Invasive Framework Reveals Region‐Specific Cerebrovascular Remodeling in Aging Using Intravital Functional Ultrasound Imaging and Ultrasound Localization Microscopy (fUS‐ULM)

Advanced Science, EarlyView.
A high‐resolution intravital imaging platform combining functional ultrasound and localization microscopy enables longitudinal, minimally invasive assessment of cerebrovascular function in aging studies. The present investigation reveals aging‐related reductions in neurovascular coupling, arteriole‐to‐venule ratio and vascular density, introducing a ...

Tailored Electro–Magnetic–Porous Multigradient Nanoarchitectonics for Absorption‐Dominated Electromagnetic Interference Shielding and Adaptive Multifunctionality

Advanced Science, EarlyView.
An electro–magnetic–porous multigradient nanofibrous electromagnetic interference (EMI) membrane is fabricated via shear‐induced in situ fibrillation and layer‐by‐layer assembly. Leveraging a multigradient‐induced “impedance matching–polarization–reabsorption” synergistic mechanism, the membrane achieves absorption‐dominated high‐efficiency EMI ...
