Protecting Orthopaedic Implants from Infection: Antimicrobial Peptide Mel4 Is Non-Toxic to Bone Cells and Reduces Bacterial Colonisation When Bound to Plasma Ion-Implanted 3D-Printed PAEK Polymers

Cells
Even with the best infection control protocols in place, the risk of a hospital-acquired infection of the surface of an implanted device remains significant.

Relay Approach: A Convergent Synthesis of Key Fragments en route to (+)‐Neosorangicin A

Chemistry – A European Journal, EarlyView.
A selective synthesis of three key fragments of the antibiotically active (+)‐neosorangicin A is reported, providing a foundation for its convergent total synthesis and proof of strategy via a relay approach. ABSTRACT Herein, we report the synthesis of the three key fragments of the macrolide antibiotic (+)‐neosorangicin A, a compound exhibiting potent

Polyether Ether Ketone Coated with Ultra-Thin Films of Titanium Oxide and Zirconium Oxide Fabricated by DC Magnetron Sputtering for Biomedical Application

, 2022
Recently, polyether ether ketone has raised increasing interest in research and industry as an alternative material for bone implants. This polymer also has some shortcomings, as it is bioinert and its surface is relatively hydrophobic, causing poor cell

Correlative Electron Paramagnetic Resonance Imaging and Atomic Force Microscopy of Lithium Deposited on Copper

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The correlation of a spectroscopic (EPRI) and microscopic (AFM) technique is demonstrated for a sample of Li deposited on Cu. Areas of different morphology were analysed. The techniques complement each other's length scales as well as the information obtained from the sample.

Impact of tear morphology and meniscal laterality on repair failure in stable knees: Medial repairs show over twofold risk

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate the failure rates of all‐inside meniscal repair based on tear morphology in stable knees (i.e., without concomitant anterior cruciate ligament reconstruction [ACLR]) and to assess the influence of failure. Methods This retrospective cohort study included 1008 patients who underwent arthroscopic all‐inside meniscal repair ...

Bucket‐handle and medial meniscal tears exhibit higher failure rates after all‐inside repair with concomitant ACL reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate failure rates across specific meniscal tear morphologies in patients undergoing all‐inside meniscal repair with anterior cruciate ligament reconstruction (ACLR), and to identify factors associated with failure. Methods This retrospective cohort included 1355 patients who underwent all‐inside meniscal repair during ACLR ...
