Brushite Boron Cement with Antibacterial Properties

Inorganic Materials: Applied Research
Boron-containing brushite cements (B-BC) for bone grafting based on B-substituted β-tricalcium phosphate (B-TCP) have been developed. The phase composition and microstructure of B-BC have been studied. It is shown that the crystalline phase of brushite is formed as a result of hardening of cements.

The Role of Brushite and Octacalcium Phosphate in Apatite Formation

Critical Reviews in Oral Biology & Medicine, 1992
Studies of apatite mineral formation are complicated by the possibility of forming several calcium phosphate phases. The least soluble, hydroxyapatite (HAP), is preferentially formed under neutral or basic conditions. In more acidic solutions phases such as dicalcium phosphate dihydrate (Brushite, DCPD) and octacalcium phosphate (OCP) are often found.

Underlying Role of Brushite in Pathological Mineralization of Hydroxyapatite

The Journal of Physical Chemistry B, 2019
The majority of human kidney stones are composed of multiple calcium oxalate crystals with variable amounts of brushite [dicalcium phosphate dihydrate (DCPD)] and hydroxyapatite (HAP) as a nucleus, in which fluid-mediated dissolution and reprecipitation may result in the phase transformation of DCPD to HAP.

The effect of hyaluronic acid on brushite cement cohesion

Acta Biomaterialia, 2009
The improvement of calcium phosphate cement (CPC) cohesion is essential for its application in highly blood perfused regions. This study reports the effectiveness of hyaluronic acids of different molecular weights in the enhancement of brushite cement cohesion.

Defluoridation of Drinking Water by Boiling with Brushite and Calcite

Caries Research, 2002
Existing methods for defluoridating drinking water involve expensive high technology or are slow, inefficient and/or unhygienic. A new method is now suggested, encompassing brushite and calcite suspension followed by boiling. Our aim was to examine the efficiency of the method and the chemical reactions involved.

Immobilization of enzymes on columns of brushite

Journal of Chromatography A, 1981
Abstract The use of brushite (CaHPO 4 ·2H 2 O) for enzyme immobilization is described and exemplified with β-galactosidase. Immobilization was carried out at 5°C in a 0.01 M Tris buffer, pH 7.6, containing 0.01 M phosphate. The immobilized enzyme showed high activity over a long period of time (after 90 days the activity was still 44% of the ...

Biological Modification in the Brushite Crystallization

MRS Proceedings, 2004
AbstractThe crystallization of brushite has been investigated in the presence of typical ionic biological components, magnesium, fluoride and citrate and a natural protein, osteopontin, using a constant composition method capable of nano-mole sensitivity. While the simple ionic additives, magnesium and fluoride do not have a significant effect, citrate

Risikofaktoren der Brushit-Steinbildung

Uro-News, 2015
Die Haufigkeit der Brushit-Steinerkrankung stieg in den vergangenen Jahrzehnten kontinuierlich an. Dennoch sind die zugrundeliegenden pathogenetischen Mechanismen und atiologischen Faktoren nur wenig bekannt. Zudem fehlen Informationen zum Stellenwert der Ernahrung.

In vitro ageing of brushite calcium phosphate cement

Biomaterials, 2003
In vivo studies investigating the use of brushite cements have demonstrated mixed results with one or more of dissolution, hydrolysis, fragmentation and long term stability being demonstrated. It has been suggested that sample volume, implant location, and species can affect in vivo behaviour.

Large Brushite Stone in a Dilated Prostatic Urethra

Journal of Urology, 1987
We report a rare case of a large brushite stone lodged in a dilated prostatic urethra. The patient had been asymptomatic except for an episode of hematuria and he underwent successful removal of the stone. The stone weighed 35 gm., had a concentric layered structure and was composed mainly of brushite.
