Solvent types used for the preparation of hydrogels determine their mechanical properties and influence cell viability through gelatine and calcium ions release

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 111, Issue 2, Page 314-330, February 2023., 2023
By the selection of the hydrogel composition, applied solvents, and concentration of the cross‐linking compound, it is possible to modify the properties of the materials designated for bioinks for 3D printing in Bone Tissue Engineering. Abstract Alginate‐gelatin hydrogels are the most commonly used materials for 3D bioprinting.

A novel model of locking plate and locking spongious screw: a biomechanical in vitro comparison study with classical locking plate

Journal of Orthopaedic Surgery and Research
Background Locking plates are commonly used for the fixation of comminuted, periprosthetic and osteoporotic bone fractures. These plates are secured to the bone with screws, creating a stable connection with fixed angle between the plate and the screws ...

Parametric Analysis of Orthopedic Screws in Relation to Bone Density [PDF]

The Open Medical Informatics Journal, 2009
A global study of geometry and material properties of orthopedic screws was performed, considering not only the effect of each single factor (screw pitch, number of threads, fillet angle, etc.) but also their interactions with respect to bone density.The stress patterns resulting from different screw geometries and bone densities were analyzed using ...

Gene Therapy Using Recombinant AAV Type 8 Vector Encoding TNAP‐D10 Improves the Skeletal Phenotypes in Murine Models of Osteomalacia

JBMR Plus, Volume 7, Issue 1, January 2023., 2023
ABSTRACT Hypophosphatasia (HPP), caused by loss‐of‐function mutations in the ALPL gene encoding tissue‐nonspecific alkaline phosphatase (TNAP), is characterized by skeletal and dental hypomineralization that can vary in severity from life‐threatening to milder manifestations only in adulthood.
