Effect of vanadate ions on the chemical precipitation of hydroxyapatite

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов
Ionic forms of V+5 are promising modifying agents for hydroxyapatite, endowing the biomaterial with increased solubility and antibacterial activity. Formation of vanadate-substituted hydroxyapatites was studied under conditions of precipitation from VO3–,

Application of hydroxyapatite implant and bone-hydroxyapatite implant into hydroxyapatite block reconstructed mandibula.

open access: yesJapanese Journal of Oral & Maxillofacial Surgery, 1991
Applying apatite implants into apatite blocks reconstructed mandibulae was performed in dogs. Apatite implants (A.I.). 5mm in diameter and 9mm in length, and implant for bone-apatite implants (B.A.T.) 4mm in diameter and 9mm in length were used in this experiment.

Micro‐Galvanic Coupling Programs the Therapeutic Zinc Ion Window to Reconfigure Immune Cascades for Pro‐Regenerative Bone Healing

open access: yesAdvanced Science, EarlyView.
This study utilized alloy micro‐galvanic coupling design to regulate the release of essential elements, thereby programming immune responses and promoting regeneration. The sacrificial anodic process of Zn‐0.8Mg reduced Zn2+ release compared to the “large cathode‐small anode” coupling of Zn‐0.8Fe.

Non‐Equilibrium Synthesis of Whitlockite Assisted by Localized H2O Vapor Pressure

open access: yesAdvanced Science, EarlyView.
A carbon substrate acts as a microheater during intense pulsed light irradiation, enabling rapid heating and cooling for whitlockite formation. In contrast to conventional white ceramic synthesis with weak photothermal response, this platform concentrates thermal energy locally and promotes phase‐selective crystallization under ultrafast ...

Natural Aging of Biomaterials in Ambient and Physiological Environments

open access: yesAdvanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

open access: yesAdvanced NanoBiomed Research, EarlyView.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.

Ein photoschaltbares Vitamin‐D‐Mimetikum mit agonistischer und antagonistischer Aktivität ermöglicht bidirektionale optische Kontrolle von VDR

open access: yesAngewandte Chemie, EarlyView.
Vitamin D entfaltet über die Aktivierung des ligandenabhängigen Transkriptionsfaktors Vitamin‐D‐Rezeptor (VDR) komplexe und zellspezifische biologische Wirkungen in verschiedenen Geweben. Das photoschaltbare Vitamin‐D‐Mimetikum 10 wechselt durch Belichtung zwischen VDR‐Antagonisten‐ (E) und Agonisten‐Aktivität (Z) und bietet eine bislang einzigartige ...

An Agonist/Antagonist Photo‐Switchable Vitamin D Mimetic Enables Bidirectional Optical Control of VDR

open access: yesAngewandte Chemie International Edition, EarlyView.
Vitamin D exhibits complex and cell‐specific biological effects in multiple tissues via activation of the ligand‐sensing transcription factor vitamin D receptor (VDR). The photo‐switchable vitamin D mimetic 10 transitions between VDR antagonist (E) and agonist (Z) activity upon illumination and offers unprecedented bidirectional optical control over ...
