Calcium phosphate coatings produced by radiofrequency magnetron sputtering method [PDF]
, 2016 Calcium phosphate coatings on titanium implants surface, produced by radio frequency (RF) magnetron sputtering method with hydroxyapatite solid target were investigated. It was found that produced coatings are calcium deficient compared to stoichiometric

Bioactivity enhancement by Sr doped Zn-Ca-P coatings on biomedical magnesium alloy
Journal of Magnesium and Alloys, 2019 The effect of strontium doped Zn-Ca-P (ZCP) coating by chemical conversion technique on the biodegradation of AZ31 alloy was evaluated. The coating formed with 1.5 wt.% Sr and 20 min phosphating time at 50 °C with pH 2.5 completely covers the alloy ...

Amorphous calcium phosphate, the lack of order is an abundance of possibilities
Biomaterials and Biosystems, 2022 For almost three decades from its discovery, amorphous calcium phosphate (ACP) was not considered a suitable biomaterial due to its structural instability.

Calcium phosphate ceramic coatings as carriers of vancomycin
Biomaterials, 1997 Infection in the setting of total joint arthroplasty remains a challenging problem. Attention has turned to developing methods of local delivery of antibiotics for prophylaxis. Vancomycin loaded into calcium phosphate ceramic coatings on titanium alloy substrates is a clinically relevant concept in the setting of total joint arthroplasty.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Calcium phosphates formation on CaTiO3 coated titanium
Journal of Materials Science: Materials in Medicine, 2007 In this study, performance of calcium phosphate formation of CaTiO3 coating film on Ti in Hanks' balanced saline solution (HBSS) was investigated. CaTiO3 thin films with a thickness of 50 nm were deposited on Ti using radiofrequency (RF) magnetron sputtering. The temperature of Ti substrate was adjusted to room temperature (RT) and 873 K.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Fabrication and Characterization of Titanium-doped Hydroxyapatite Thin Films
, 2007 Hydroxyapatite [Ca10(PO4)6(OH)2, HA] is used in many biomedical applications including bone grafts and joint replacements. Due to its structural and chemical similarities to human bone mineral, HA promotes growth of bone tissue directly on its surface ...
