A Self‐Curling Si3N4‐Biofunctionalized Nerve Wrap for Suture‐Free Peripheral Nerve Repair with Multimodal Regenerative Bioregulation

Advanced Functional Materials, EarlyView.
Si3N4‐enhanced bioactive nanostructured adhesive wrap enables rapid conduit formation in wet environments, simplifying surgical procedures. Incorporated Si3N4 undergoes controlled hydrolysis within nanofibers, multi‐directionally modulating the peripheral nerve repair microenvironment for effective suture‐free repair.

Effectiveness of vascularized and conventional bone grafting in achieving union in humeral pseudarthrosis

Гений oртопедии, 2021
Introduction Humeral fractures comprise from 5 % to 8 % of all fractures. Nonunion rate of humeral fractures is 5.5–8.7% with open reduction and internal fixation (ORIF) technique and 3–5.6 % with the use of locked intramedullary nailing technique.

LipoGels: Robust Self‐Lubricating Physically Cross‐Linked Alginate Hydrogels Embedded with Liposomes

Advanced Functional Materials, EarlyView.
Physically cross‐linked alginate hydrogels embedded with 1,2‐dipalmitoyl‐sn‐glycero‐3‐phosphocholine liposomes (LipoGels) are prepared under optimized conditions to avoid shrinkage and achieve structural uniformity. LipoGels demonstrate robust mechanical strength (Young's modulus ≈1 MPa), excellent lubrication (friction coefficient ≈0.021), and ...

Tailoring the Properties of Functional Materials With N‐Oxides

Advanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Loss of correction in unstable comminuted distal radius fractures with external fixation and bone grafting -a long term followup study

Journal of Orthopaedic Surgery and Research, 2011
Over the years, management of complex distal radius fractures by closed means has often failed leading to late collapse. We have chosen the principle of ligamentotaxis using external fixation and bone grafting in this study to prevent late complications.

Insight into the Internal Structure of Biogenic, Synthetic and Geological Apatite by Electron Microscopy and X‐Ray Scattering

Advanced Functional Materials, EarlyView.
Apatite occurs in many forms in nature, e.g. in teeth and geological minerals. Internally, biological apatite contains nanocrystals that are also found in synthetically prepared calcium phosphate nanoparticles which are used in biomedicine, e.g. for gene and drug delivery and for bone regeneration. Abstract Calcium phosphate is the inorganic component (
