Formation of Hydroxyapatite-Based Hybrid Materials in the Presence of Platelet-Poor Plasma Additive

open access: yesBiomimetics, 2023
Biomaterials based on hydroxyapatite with controllable composition and properties are promising in the field of regenerative bone replacement. One approach to regulate the phase composition of the materials is the introduction of biopolymer-based ...

Fluoride Plus Calcium Phosphate Varnishes: A Possible Link between Mineral Phase Formations and Observed Clinical Outcomes

open access: yesDental Hypotheses, 2021
Introduction: Incorporation of calcium phosphate agents into fluoride varnishes might improve anticaries benefits. But when clinical results do not mirror this view, explanations remain unclear.

Solid Phases Precipitating in Artificial Urine in the Absence and Presence of Bacteria Proteus mirabilis—A Contribution to the Understanding of Infectious Urinary Stone Formation

open access: yesCrystals, 2018
Magnesium ammonium phosphate hexahydrate, called struvite, is the dominant component of infectious urinary stones. In addition to struvite, infectious urinary stones include solid phases with poor crystallinity as well as amorphous matter.

PRECIPITATION OF HYBRID HYDROXYAPATITE / AUTOFIBRIN NANOCOMPOSITES

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2021
Hybrid composites based on hydroxyapatite and autofibrin were synthesized by precipitation in a medium with pH=9. Soft precipitation conditions and rapid isolation of the composite precipitates favored preservation of a biopolymer matrix of autofibrin ...

Physiological and genetic characterization of calcium phosphate precipitation by Pseudomonas species

open access: yesScientific Reports, 2018
Microbial biomineralization is a widespread phenomenon. The ability to induce calcium precipitation around bacterial cells has been reported in several Pseudomonas species but has not been thoroughly tested. We assayed 14 Pseudomonas strains representing

Effect of Ca-P compound formed by hydrothermal treatment on biodegradation and biocompatibility of Mg-3Al-1Zn-1.5Ca alloy; in vitro and in vivo evaluation

open access: yesScientific Reports, 2017
Chemical combinations of Ca-P produced via plasma electrolytic oxidation (PEO) and a hydrothermal treatment were fabricated to improve the initial corrosion resistance and biocompatibility of a biodegradable Mg-3Al-1Zn-1.5Ca alloy.
