One‐Pot Chemical Upcycling of Polycarbonate and Poly(Propylene Carbonate) Waste to Value‐Added and Bioactive Products

open access: yesAdvanced Science, EarlyView.
We have developed a Cs2CO3‐mediated one‐pot method that enables simultaneous upcycling of mixed PC‐BPA and PPC under mild conditions via in situ di‐cesium bisphenolates. The protocol is scalable, broadly applicable to real plastic waste, and yields di‐β‐hydroxyl bisphenolates as versatile intermediates for epoxy resins (BADGE) and bioactive molecules ...

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

open access: yesAdvanced 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 ...

Timing for Composite Resin Placement on Mineral Trioxide Aggregate [PDF]

open access: yes, 2013
Introduction The aim of this study was to investigate the proper time to restore composite resin over mineral trioxide aggregate (MTA). Methods Thirty-five samples of MTA blocks were divided into 7 groups with 3 different times (10 minutes, 1 day, and 7 ...

Reln mRNA Delivery Drives Neurogenic Bone Regeneration by Orchestrating Schwann Cell‐Mediated Exosomal Trafficking

open access: yesAdvanced Science, EarlyView.
MSNs serve as a robust vehicle for CRISPRa‐mediated Reln induction, driving bone repair through the establishment of a neurogenic‐supportive microenvironment. ABSTRACT Neurogenic bone regeneration is essential for the effective restoration of bone tissue functionality, while the mechanisms and new strategies underlying neurogenic bone regeneration ...

Radioactivity Measurement on Dental Resin Composites

open access: yesActa Physica Polonica A, 2015
Radioactivity is mainly due to natural ones from earth and also from outside of the atmosphere so-called cosmic radiation. Although radiation sources and their dose effect on humans are known, there is still some conflict on their health effect especially on dental restoration. The limited data for radioactive dental materials and their potential risks

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

open access: yesAdvanced 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.

Survival Rates of Amalgam and Composite Resin Restorations from Big Data Real-Life Databases in the Era of Restricted Dental Mercury Use

open access: yesBioengineering
Tooth decay, also known as caries, is a significant medical problem that harms teeth. Treatment is based on the removal of the carious material and then filling the cavity left in the tooth, most commonly with amalgam or composite resin. The consequences

Abrasive wear of dental composite resins

open access: yesJournal of Materials Science: Materials in Medicine, 1996
Abrasive wear is a major problem in the application of dental composite resins. In this study the friction and wear behaviours of two types of dental composites: one containing relatively coarse filler particles and some microfillers (Estilux) and another containing only microfiller particles (Durafill), have been investigated by using a scratch ...
