Capillary‐Driven 3D Open Fluidic Networks for Versatile Continuous Flow Manipulation

Advanced Materials, EarlyView.
The capillary‐driven 3D open fluidic networks (OFNs), composed of connected polyhedral frames, enable precise, programmable, and versatile manipulation of unary, binary, and multiple continuous flows in both spatial and temporal dimensions. OFNs represent a significant leap beyond conventional microfluidics, unlocking new possibilities for selective ...

A Comparative Investigation of the Microleakage of Biodentine and Mineral Trioxide Aggregate as Coronal Barrier in Nonvital Bleaching

Journal of Mazandaran University of Medical Sciences, 2020
Background and purpose: Internal bleaching is recommended to correct the discoloration of pulpless teeth. This study aimed to compare the microleakage of biodentine and mineral trioxide aggregate (MTA) used as an intracanal barrier in non-vital bleaching.

Autonomous Implants

Advanced Materials, EarlyView.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.

Bacterial Leakage Assessment for Different Types of Resin-Based Dental Restorations Applied Using Various Placement Methods

Journal of Dental Materials and Techniques, 2014
Introduction: Although composite resins have improved greatly since their introduction, microleakage is one of the most frequently encountered problems. This study compared the effects of different monomer systems and layering techniques on the bacterial leakage of Cl I composite resin restorations.

Antimicrobial Multi‐Assay Evaluation of (Al‐Doped ZnO)‐Ag and TiO2‐Ag Nanocoatings: Impact of Direct and Indirect Mechanisms

Advanced Materials Interfaces, EarlyView.
This work explores the antimicrobial action of AZO‐Ag and TiO2‐Ag nanocoatings on plastic, demonstrating good efficacy against highly‐critical antibiotic‐resistant bacteria, yeast, and virus. A multi‐assay approach is here exploited to inspect the contribution of direct and indirect antimicrobial mechanisms, and potential human toxicity is also ...

Essential lipid autacoids rewire mitochondrial energy efficiency in metabolic dysfunction‐associated fatty liver disease

Hepatology, EarlyView., 2022
Increased liver content of DHA‐derived small lipid autacoids (i.e resolvin D1 and maresin 1) associates with enhanced mitochondrial oxidative phosphorylation, fatty acid β‐oxidation and bioenergetic metabolic flux. These features provide hepatic protection from steatotic, pro‐inflammatory and fibrogenic insults.
