The efficacy of hydroxyapatite (HAp) as a carrier was investigated to establish a method of local administration of bisphosphonates (Bps), which has currently been administered systemically. HAp granules (300-500 microm in size) with different physicochemical features were prepared by altering the sintering temperature. To ascertain the physicochemical properties of the HAp granules, their crys...

At CITO Clinic of bone pathology new biocomposite material Osteomatrix was used in 15 patients (mainly with tumors and tumor-like diseases) for the plasty post-resection defects. is composed collagen, hydroxyapatite sulfated glycosaminoglycanes. produced at together Conectbiopharm Ltd. form granules blocks. Observation dynamics roentgenologic control showed good tolerance by distinct accelerate...

This study is aimed at the development of a method to fabricate porous spherical hydroxyapatite (HA)—fluorapatite (FA) granules. The method to produce porous granules is based on liquid immiscibility effect. A suspension of HA–FA powder mixtures in aqueous solution of gelatin and oil as a dispersion media were used. By stirring the mixtures of these immiscible liquids, granules of 50–200 mm dia...

Abstract The aim of the present study was to perform a detailed morphological analysis an injectable platelet rich fibrin after combination with two different particulate hydroxyapatite-based granules, porous zirconia block, and laser-textured or titanium surfaces. Blood samples were harvested from three participants prepare flowable PRF in contact not hydroxyapatite (Hap), bone mineral granule...

Precipitation and accumulation of calcium phosphate in granular sludge has attracted research attention recently for removal recovery from wastewater. This study investigated granulation stage to steady state by forming heterotrophic granules at different COD/N ratios 21 32 °C, respectively, followed the transformation partial nitrifying granules. It was found that mature accumulated around 60–...

Nanocrystalline hydroxyapatite containing selenite ions (SeHA; 9.6 wt.% of selenium) was synthesized using wet method and subject to careful physicochemical analysis by powder X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, solid-state nuclear magnetic resonance, wavelength dispersive X-ray fluorescence, and inductively coupled plasma optical emissi...

The one-stage partial nitritation and anammox process with the hydroxyapatite (HAP)-based syntrophic granules was studied for ammonium nitrogen removal from effluents of a self-agitated anaerobic baffled reactor treating fish processing wastewater. When in influent 1140 mg N·L-1, high rate efficiency 1.51 ± 0.10 kg N·m−3·d-1 88.2% were obtained, respectively. Anammox bacteria Candidatus Kueneni...

The need for development of comprehensive therapeutic systems, (e.g., polymer-apatite composites) as a bone substitute material has previously been highlighted in many scientific reports. The aim of this study was to develop a new multifunctional composite based on hydroxyapatite porous granules doped with selenite ions (SeO₃2-) and a biodegradable branched copolymer-bisphosphonate conjugate as...

Although blockor granular-type sintered hydroxyapatite are known to show excellent tissue responses and good osteoconductivity, apatite powder elicits inflammatory response. For the fabrication of hydroxyapatite block or granules, sintering is commonly employed. However, the inorganic component of bone and tooth is not high crystalline hydroxyapatite but low crystalline B-type carbonate apatite...
