A Closed‐Loop‐Capable Neural Interface Platform for Deep Brain Modulation via Integrated Non‐Viral Gene Delivery, NIR Optogenetics, and Electrophysiological Recording

Advanced Science, EarlyView.
A multifunctional, 3D porous neural interface combines non‐viral gene delivery and NIR optogenetics to enable minimally invasive, closed‐loop modulation of deep‐brain circuits. Abstract Closed‐loop neuromodulation requires precise, stable, and cell‐specific control of neural circuits with minimal invasiveness.

Elevator‐Like Hollow Channels in Porous Scaffolds Accelerate Vascularized Bone Regeneration via NETs‐Fibrin‐Mediated Macrophage Recruitment

Advanced Science, EarlyView.
This study demonstrates that how hollow‐channel scaffolds promote vascularized bone regeneration via an immunomodulatory mechanism. The channel structures facilitate the formation of a neutrophil extracellular traps‐fibrin scaffold that recruits vascular endothelial growth factor A (VEGF‐A)‐secreting M2 macrophages to drive angiogenesis. Combining this

Targeting the GPX4–FUNDC1 Interaction with Magnesium Lithospermate B Attenuates Sepsis‐Associated Lung Injury

Advanced Science, EarlyView.
The diagram depicts the endothelial‐protective mechanism of magnesium lithospermate B (MLB) in sepsis‐associated lung injury. MLB binds GPX4 at Gly79, disrupts its interaction with FUNDC1, prevents mitophagy‐mediated GPX4 degradation, restores mitophagic flux, reduces ROS, and limits ferroptosis.

Effect of Light Direction on the Microleakage of Micro Filled and Hybrid Resin Composites

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2010
Introduction: One of the most important factors affecting the marginal seal of composite restorations is polymerization shrinkage. The aim of this study was to evaluate the micro leakage of two resin composites cured with two light directions.

Effect of Mechanical Load Cycling on Microleakage of Restorative Glass Ionomers Compared to Flowable Composite Resin in Class V Cavities

Frontiers in Dentistry, 2019
Objectives: Microleakage is the most important factor responsible for the destruction of restoration margins. The aim of this study was to assess the effect of mechanical load cycling on microleakage of four types of glass ionomer cement (GIC) in ...

Dissolution Study of Biodegradable Magnesium Silicide Thin Films for Transient Electronic Applications

Advanced Science, EarlyView.
Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...

Micro‐Organ Chip Deciphers Tumor‐Derived G‐CSF as Remote Commander of Lung Pre‐Metastatic Niche via VEGFA‐KDR Cascade

Advanced Science, EarlyView.
Breast cancer reprograms the lung into a receptive pre‐metastatic niche via a novel G‐CSF–VEGFA–KDR signaling axis. Using a micro‐organ chip that enables contact‐independent coculture, this study uncovers how tumor‐secreted G‐CSF activates lung capillary KDR to drive angiogenesis and prime the soil for metastasis—without direct tumor contact.

CD147/Basigin: From Integrative Molecular Hub to Translational Therapeutic Target

Advanced Science, EarlyView.
This review conceptualizes CD147 as a fundamental “Energy‐Structure Coupler,” physically bridging metabolic flux (via MCTs) with morphogenetic plasticity (via integrins/MMPs) to drive cancer, infection, and autoimmunity. Addressing the “specificity paradox” that limits current translation, the authors chart a strategic roadmap—spanning logic‐gated ...

Precision‐Engineered Silver Single‐Atom Carbon Dot Nanozymes for Theranostic Management of Acute Kidney Injury

Advanced Science, EarlyView.
Mitochondria‐targeted silver single‐atom carbon dot (T‐AgSA‐CDs) nanozymes enable dual SOD/GPx‐like ROS scavenging, real‐time imaging, and therapeutic effects for acute kidney injury (AKI). Atomically dispersed Ag sites synergize with carbon dots to restore renal redox hemostasis, protect mitochondrial function, mitigate inflammation, facilitate post ...
