One of the promising fields research is tissue engineering that can facilitate available therapeutic methods. Nanosized hydroxyapatite (HA) one key elements in mineral bone. It possible to affect surrounding osteoprogenitor cells using nano-sized HA and through this improve bone repair changing paracrine signaling. The present paper an attempt prepare evaluate physicochemical properties hydroxy...

A series of nano hydroxyapatite-gelatine composites with different dilute solutions of gelatine concentrations were synthesized by a thermally assisted low-power ultrasonic irradiation method. The gelatine hydroxyapatite, (Gel-HAP) nanoparticles were prepared using Ca(NO(3))(2) and KH(2)PO(4) in the presence of gelatine in an aqueous solution. The synthesised products were heat treated between ...

Synthetic calcium phosphates, e.g., hydroxyapatite (HAP) and tricalcium phosphate (TCP), are the most commonly used bone-graft materials due to their high chemical similarity natural hydroxyapatite—the inorganic component of bones. Calcium in form a free ion or bound complexes plays key role many biological functions, including bone regeneration. This paper explores possibility increasing Ca2+-...

In this paper, we report the structural and morphological properties of silver-doped hydroxyapatite (AgHAp) with a silver concentration x Ag = 0.5 before and after being thermal treated at 600 and 1000 °C. The results obtained by X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Raman spectroscopy suggest that the structure of the samples changes gradually, from hydro...

BACKGROUND The purpose of this study was to examine the possible contribution of calcifying nanoparticles to the pathogenesis of placental calcification. METHODS Calcified placental tissues and distal tissue samples were collected from 36 confirmed placental calcification cases. In addition, 20 normal placental tissue samples were obtained as a control group. All the tissue samples were cultu...
