Real‐Time In Vivo Cellular‐Level Imaging During Puncture

open access: yesAdvanced Science, EarlyView.
We present an artificial‐intelligence‐empowered integrative‐light‐field microendoscopy (AIM) needle that delivers real‐time in vivo, diffraction‐limited cellular‐level imaging during puncture and visualizes layered microstructures along the needle path. As a microscopic complement to CT/ultrasound, it improves sampling localization and adds preliminary

Radical‐Mediated, Substrate‐Independent Fabrication of Hybrid Solid–Hydrogel Materials With Tunable Crosslinking: An Initiator‐ and Crosslinker‐Free Approach

open access: yesAdvanced Science, EarlyView.
This work introduces a substrate‐independent, reagent‐free plasma strategy that forms radical‐rich interlayers for covalent hydrogel attachment without initiators or crosslinkers. The long‐lived radicals drive in situ gelation, creating robust, cytocompatible hybrid solid–hydrogel constructs across diverse substrates.

Restoring Lateral Incisors and Orthodontic Treatment: Perceptions among General Dentists and Othodontists [PDF]

open access: yes, 2015
The purpose of this study was to identify and compare preferences and perceptions of orthodontists and general dentists when restoring peg-shaped lateral incisors. The investigation sought to summarize these preferences with regard to treatment planning,

AXL Promotes Ischemic Myelin Repair Through Alleviating Myelin Debris Deposition and Lipid Droplets Accumulation

open access: yesAdvanced Science, EarlyView.
Microglial AXL drives white matter repair after stroke by orchestrating the cleanup of myelin debris. Mechanistically, AXL signals through EGR1 to boost Smpd1 transcription, regulating sphingolipid metabolism and preventing lipid droplet toxicity. Restoring the pathway with ASM therapy mitigates damage, positioning AXL as a key node for therapeutic ...

Macrophage–Derived Ferritin Exacerbates Silica‐Induced Pulmonary Fibrosis via PIK3R2‐Mediated Fibroblast Differentiation

open access: yesAdvanced Science, EarlyView.
This study identifies ferritin as a pivotal mediator of silica‐induced pulmonary fibrosis. Macrophage‐derived ferritin drives fibroblast‐to‐myofibroblast differentiation via the PIK3R2/SMAD pathway, while ferritin knockdown alleviates fibrosis. These findings define ferritin as both a biomarker and pathogenic driver, highlighting ferritin‐PIK3R2 ...

Cortical Somatostatin Neurons Regulate Seizure Susceptibility via MINAR1/Gαs–cAMP Signaling

open access: yesAdvanced Science, EarlyView.
Our study identifies MINAR1 as a novel regulator of cortical interneuron excitability and seizure susceptibility. MINAR1 is preferentially expressed in SST+ interneurons. Genetic ablation of MINAR1 leads to seizure hypersensitivity, reduced SST+ neuron excitability, and impaired Gαs–cAMP signaling, disrupting the E/I balance.

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

open access: yesAdvanced 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 ...

A 3D Finite Element Analysis on Stress Distribution of Two Ceramic Materials Used for Fabrication of Laminate Veneers using Two Preparation Designs: An In-vitro Study

open access: yesJournal of Clinical and Diagnostic Research
Introduction: Veneers have been successfully used in cases of aesthetic and cosmetic dentistry. As the thickness of veneers needs to be 0.5 mm to enable bonding to enamel, the preparation of teeth is crucial to ensure longevity.
