Calcium Phosphate Biomaterials for 3D Bioprinting in Bone Tissue Engineering

Biomimetics
Three-dimensional bioprinting is a promising technology for bone tissue engineering. However, most hydrogel bioinks lack the mechanical and post-printing fidelity properties suitable for such hard tissue regeneration.

Effects of Low-Phosphorus Diets Supplemented with Phytase on the Production Performance, Phosphorus-Calcium Metabolism, and Bone Metabolism of Aged Hy-Line Brown Laying Hens

Animals, 2023
This study was conducted to evaluate the effects of phytase supplementation in low-phosphorus diets on the production performance, phosphorus–calcium metabolism, and bone metabolism in laying hens from 69 to 78 weeks of age. Hy-Line Brown laying hens (n =

Calcium phosphates in biomedical applications: materials for the future?

, 2016
Our populations are aging. Some experts predict that 30% of hospital beds will soon be occupied by osteoporosis patients. Statistics show that 20% of patients suffering from an osteoporotic hip fracture do not survive the first year after surgery, all ...

Biomimetic Versus Sintered Calcium Phosphates: The In Vitro Behavior of Osteoblasts and Mesenchymal Stem Cells

Tissue Engineering. Part A, 2017
The fabrication of calcium phosphates using biomimetic routes, namely, precipitation processes at body temperature, results in distinct features compared to conventional sintered calcium phosphate ceramics, such as a high specific surface area (SSA) and ...

Effect of type of calcium phosphate on microstructure and properties of glass reinforced biocomposites [PDF]

Processing and Application of Ceramics, 2007
In the present study two different types of calcium phosphates (synthetic calcium phosphates (SCP) and biogenic hydroxyapatite (BHA)) were used to produce porous biocomposites with addition of 35.5–41.0 wt% SiO2-Na2O-B2O3 glass.

Calcium-binding capacity of organic and inorganic ortho- and polyphosphates

, 2009
The aim of this research was to determine the calcium-binding capacity of inorganic and organic ortho- and polyphosphates. This calcium-binding capacity can be used to influence the stability of, for example, casein micelles in dairy systems.

Junctate is a key element in calcium entry induced by activation of InsP3 receptors and/or calcium store depletion [PDF]

, 2004
In many cell types agonist-receptor activation leads to a rapid and transient release of Ca(2+) from intracellular stores via activation of inositol 1,4,5 trisphosphate (InsP(3)) receptors (InsP(3)Rs).

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
