Rapid association of unconjugated bilirubin with amorphous calcium phosphate.

Journal of Lipid Research, 1995
The association of unconjugated bilirubin (UCB) with amorphous calcium phosphate was studied in vitro. To this end UCB, solubilized in different micellar bile salt solutions, was incubated with freshly prepared calcium phosphate precipitate.

How to build a bone? - Hydroxyapatite or Posner’s clusters as bone minerals

Open Ceramics, 2021
For decades, hydroxyapatite has been considered the main mineral phase of mammalian tooth enamel and bone that crystallizes from a precursor phase, amorphous calcium phosphate.

Pure hydroxyapatite synthesis originating from amorphous calcium carbonate

Scientific Reports, 2021
We report a synthesis strategy for pure hydroxyapatite (HAp) using an amorphous calcium carbonate (ACC) colloid as the starting source. Room-temperature phosphorylation and subsequent calcination produce pure HAp via intermediate amorphous calcium ...

Osteogenic potential of poly(ethylene glycol)-amorphous calcium phosphate composites on human mesenchymal stem cells

Journal of Tissue Engineering, 2020
Synthetic hydrogel-amorphous calcium phosphate composites are promising candidates to substitute biologically sourced scaffolds for bone repair. While the hydrogel matrix serves as a template for stem cell colonisation, amorphous calcium phosphate s ...

Triggered metabolism of adenosine triphosphate as an explanation for the chemical heterogeneity of heterotopic ossification

Communications Chemistry, 2023
Heterotopic ossification (HO), the pathological formation of bone in soft tissues, is a debilitating condition, as well as one of the few instances of de novo bone formation in adults.

EFFECT OF TWO REMINERALIZING AGENTS ON MICROHARDNESS OF INITIAL ENAMEL CARIESLIKE LESIONS IN YOUNG PERMANENT TEETH [PDF]

Alexandria Dental Journal, 2019
INTRODUCTION: Dental caries in enamel is unique amongst diseases as enamel is both acellular and avascular. Thus, in contrast to other tissues, enamel cannot heal itself by a cellular repair mechanism.

Characterization of the adsorption of conjugated and unconjugated bile acids to insoluble, amorphous calcium phosphate.

Journal of Lipid Research, 1994
Recently we showed that supplemental dietary calcium stimulates the intestinal formation of insoluble calcium phosphate and decreases the ratio of dihydroxy to trihydroxy bile acids in human duodenal bile. Because previous in vitro studies indicated that

Preparation of protamine-adsorbed calcium phosphate powders and their antibacterial property

Journal of Asian Ceramic Societies, 2022
Calcium phosphates are key biomaterials in bone regeneration and dental treatment fields. Biomaterials must exhibit antibacterial properties to ensure protection against microbial infection in implantation frameworks.
