Effect of nano-fluorapatite filler particles on surface microhardness and mineralization capacity of an experimental oral film

Bulletin of the National Research Centre
Background The objective of the study was to prepare and assess novel remineralizing oral films loaded with fluorapatite powder and composed of a combination of hydroxyethyl cellulose (HC) and cellulose nanofibers (CF).

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

In vitro evaluation of the physical characteristics and push-out bond strength of new experimental nano-MTA

Bulletin of the National Research Centre
Background This research assessed two materials to be used as endodontic sealing material. The setting time, pH change, calcium ions release, microhardness and push-out bond strength were compared.

Solubility, pH change, and calcium ion release of low solubility endodontic mineral trioxide aggregate

Bulletin of the National Research Centre, 2020
Background Insolubility is the main requirement for ideal root end filling material to provide perfect sealing ability. Moreover, alkalinity and bioactivity provide great chance for tissues healing and remineralization.

Biocompatibility Evaluation of Resin-Based Restorative Materials: A Review

European Annals of Dental Sciences, 2021
Biocompatibility is described as an appropriate biological response of a biomaterial in a living organism. It is known that biomaterials are not inert and the materials should be tested before they are allowed to be used in clinical practice.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
