Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization

Advanced Science, EarlyView.
Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...

Mn/Zn Bimetallic MOF‐Integrated Hydrogel Alleviates Excessive Mitochondrial Fission in BMSCs to Promote Osteoporotic Jawbone Repair

Advanced Science, EarlyView.
Excessive reactive oxygen species (ROS) and chronic inflammation impair bone marrow‐derived mesenchymal stem cells (BMSCs), contributing to poor healing in osteoporotic jawbone defect. The gelatin methacryloyl hydrogel loaded with manganese‐doped zeolitic imidazolate framework (Mn‐ZIF‐8@GelMA) promotes regeneration through redox regulation and ...

PIAS3 CircRNA‐Loaded Lipid Nanoparticles Restore ALOX15 SUMOylation to Suppress Cementoblast Ferroptosis and Attenuate Orthodontically Induced Root Resorption

Advanced Science, EarlyView.
Orthodontic compression suppresses PIAS3 expression in cementoblasts, impairing ALOX15 SUMOylation and ubiquitin‐mediated degradation, which leads to ALOX15 accumulation, lipid peroxidation, ferroptosis, and osteoclastogenesis. Local delivery of PIAS3 circRNA‐loaded lipid nanoparticles restores the PIAS3–ALOX15 regulatory pathway, alleviates ...

A Soft Robotic Finger With Deep Learning‐Enhanced Tactile Sensing for Texture and Softness Recognition

Advanced Intelligent Systems, EarlyView.
Inspired by human touch, a tendon‐driven soft robotic finger combines multimodal tactile sensing and deep learning to simultaneously perceive texture and softness on deformable surfaces. A CNN‐LSTM model fuses pressure, accelerometer, and gyroscope signals to accurately classify material properties, achieving up to 95.4% texture and 97.0% softness ...

High Diagnosis Rate for Nonimmune Hydrops Fetalis With Prenatal Clinical Genome: Expanded Results From the Hydrops‐Yielding Diagnostic Results of Prenatal Sequencing (HYDROPS) Study

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nonimmune hydrops fetalis (NIHF) is characterized by abnormal fluid accumulation in ≥ 2 fetal compartments and may be genetic. The incremental diagnostic yield of prenatal exome sequencing (ES) for NIHF following a negative standard workup was previously explored on 22 cases.

Tooth loss and obstructive sleep apnoea

Respiratory Research, 2006
Background Complete tooth loss (edentulism) produces anatomical changes that may impair upper airway size and function. The aim of this study was to evaluate whether edentulism favours the occurrence of obstructive sleep apnoea (OSA).
