Clindamycin-Loaded Nanosized Calcium Phosphates Powders as a Carrier of Active Substances

open access: yesNanomaterials, 2023
Bioactive calcium phosphate ceramics (CaPs) are one of the building components of the inorganic part of bones. Synthetic CaPs are frequently used as materials for filling bone defects in the form of pastes or composites; however, their porous structure ...

Assessment of Healing Potential of Alginate and Chitosan-Based Biomaterials for Cranial Bone Defects in Experimental Model. [PDF]

open access: yesBiomed Res Int
The healing of bone defects in the skull vault is a serious clinical problem. The aim of this study is to evaluate the effect of two osteoplastic materials on the healing of a cranial vault experimental defect by computed tomography. Two material systems are analyzed in detail: (i) a sodium alginate–based matrix modified with hydroxyapatite ...

Strontium Ions Substitution in Brushite Crystals: The Role of Strontium Chloride

open access: yesJournal of Functional Biomaterials, 2011
The incorporation of strontium chloride to brushite cement was successful to introduce strontium ions within the lattice of brushite crystals. The effect of strontium ions on brushite cement properties was concentration dependent; such that, the addition

The Effect of Full-Scale Exchange of Ca2+ with Zn2+ Ions on the Crystal Structure of Brushite and Its Phase Composition

open access: yesBiomimetics, 2023
This study was carried out to investigate the effect of a complete exchange of Ca2+ with Zn2+ ions on the structure of brushite (CaHPO4·2H2O), which might be advantageous in the production process of CaxZn1−xHPO4·nH2O.

Time-resolved Raman spectroscopy for in situ planetary mineralogy [PDF]

open access: yes, 2010
Planetary mineralogy can be revealed through a variety of remote sensing and in situ investigations that precede any plans for eventual sample return. We briefly review those techniques and focus on the capabilities for on-surface in situ examination of ...
