Sintering and robocasting of β-tricalcium phosphate scaffolds for orthopaedic applications
Acta Biomaterialia, 2006 beta-Tricalcium phosphate (beta-TCP) scaffolds with designed, three-dimensional (3-D) geometry and mesoscale porosity have been fabricated by direct-write assembly (robocasting) techniques. Concentrated beta-TCP inks with suitable viscoelastic properties were developed to enable the fabrication of the complex 3-D structures.

Heparinization of Beta Tricalcium Phosphate: Osteo‐immunomodulatory Effects [PDF]
Advanced Healthcare Materials, 2017 AbstractImmune cells play a vital role in regulating bone dynamics. This has boosted the interest in developing biomaterials that can modulate both the immune and skeletal systems. In this study, calcium phosphates discs (i.e., beta‐tricalcium phosphate, β‐TCP) are functionalized with heparin to investigate the effects on immune and stem cell responses.

Microporous Ceramics Based on β-Tricalcium Phosphate
Ceramics, 2022 Microporous ceramic material, based on β-tricalcium phosphate β-Ca3(PO4)2 with grain size 2–5 μm, pore size smaller than 10 mm, and density 1.22 g/cm3 corresponding to ~40% of the theoretical density (3.07 g/cm3) of β-Ca3(PO4)2, was obtained from a powder mixture with a given molar ratio Ca/P = 1.5 after firing at 1100 °C.

On the emergence of P-Loop NTPase and Rossmann enzymes from a Beta-Alpha-Beta ancestral fragment
eLife, 2020 This article is dedicated to the memory of Michael G. Rossmann. Dating back to the last universal common ancestor, P-loop NTPases and Rossmanns comprise the most ubiquitous and diverse enzyme lineages.

Restoration of PITPNA in Type 2 diabetic human islets reverses pancreatic beta-cell dysfunction
Nature Communications, 2023 Defects in insulin processing and granule maturation are linked to pancreatic beta-cell failure during type 2 diabetes (T2D). Phosphatidylinositol transfer protein alpha (PITPNA) stimulates activity of phosphatidylinositol (PtdIns) 4-OH kinase to produce

β-Tricalcium Phosphate Coating on Titanium
Journal of the Ceramic Society of Japan, 1991 Bioactive β-tricalcium phosphate (β-TCP) coating onto titanium was studied. It is shown that the β-TCP adhered to the surface of a titanium plate by the use of a frit, which was composed of CaO, TiO2, P2O5 and a few mol% Na2O. The frit as a coated layer resulted in the formation of β-TCP and CaTi4(PO4)6 phases by a thermal treatment at 800°C for 24h.
