Generation of Self‐Organizing Macrovascular Constructs by Bioprinting Human iPSC‐Derived Mesodermal Progenitor Cells

Advanced Science, EarlyView.
ABSTRACT Vascularization remains a major obstacle in tissue engineering. Here, we introduce a bioprinting strategy to generate centimeter‐scale, self‐organizing “mother vessel” constructs from iPSC‐derived hiMPCs. By optimizing bioink composition, printing was accomplished in a single‐step approach. Within one week, hiMPCs differentiated into both CD31+

Spatiotemporal Targeting Randle Cycle and Immune Checkpoint for Potent Antitumor Therapy

Advanced Science, EarlyView.
A glucose oxidase‐based nanogel (GOX‐NG) system using catechol‐functionalized alginate, exhibits enhanced tumor penetration, prolonged retention, and sustained glucose depletion in the tumor microenvironment. When combined with a fatty acid oxidation inhibitor, it implements dual metabolic suppression, thereby enhancing ROS‐induced immunogenic cell ...

Post retention strength of apical and conventional coating obturation methods using bioceramic sealer: a laboratory investigation

BMC Oral Health
Background Once bioceramic sealer (BCS) enters the dentinal tubules, it cannot be reliably removed. BCS-occupied dentinal tubules reduce fibre post retention strength.

Accuracy of Ceramic Restorations Made Using an In-office Optical Scanning Technique: An In Vitro Study

, 2014
The present in vitro study concerns determination of the pre-cementation gap width of all-ceramic crowns made using an in-office digital-impression technique and subsequent computer-aided design/computer-aided manufacturing (CAD/CAM) production.

EpCAM+ Extracellular Vesicle PD‐L1 Dynamics as a Predictive Biomarker of Immune Checkpoint Blockade Response

Advanced Science, EarlyView.
A highly sensitive SERS‐based platform measures PD‐L1 expression on EpCAM+ circulating EVs from cancer patients undergoing immunotherapy. Monitoring dynamic changes after treatment reveals that reduced EpCAM+ EV PD‐L1 levels associate with improved long‐term clinical outcomes, establishing a non‐invasive approach for tracking immune checkpoint ...

Long-term influence of applied dentin sealing techniques and luting material type on the bond durability of a resin CAD/CAM restorative material

BMC Oral Health
Background The durability of bonded CAD/CAM restorations depends largely on effective adhesion to dentin. Immediate dentin sealing (IDS) has been proposed to enhance bonding effectiveness compared with conventional delayed dentin sealing (DDS ...

Smart Denture with Embedded Thin‐Film Temperature Sensors Patterned by Femtosecond Laser Pulse for Elderly Healthcare

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
We demonstrate the direct‐laser patterning of a gold thin film on polymethyl methacrylate to fabricate a temperature sensor for dentures. The temperature sensor‐embedded smart dentures are evaluated in an oral environment, enabling in‐situ monitoring for elderly healthcare.

Human Leukocyte Elastase Triggered Nanoparticles for Targeted Antimicrobial Delivery and Oral Microbial Modulation

Advanced NanoBiomed Research, EarlyView.
This study explores enzyme‐responsive nanoparticles for targeted antimicrobial release in inflamed oral environments. Nanoparticles formed by complexing peptides and chlorhexidine respond to human leukocyte elastase and release chlorhexidine selectively. P7 (ECAAPVCE)‐based formulations show optimal properties and stability, with antimicrobial activity
