The present work reports the development of a low-cost and reliable differential pulse adsorptive stripping voltammetric procedure for the detection of diquat (DQ) in water, using a glassy carbon electrode (GCE) modified with β-cyclodextrin (β-CD)/Natural hydroxyapatite (NHAPP0.5) composite material. The structural characterization of the natural h...

Aseptic loosening and bacterial infections are the two main causes of failure for metallic implants used for joint replacement. A coating that is both bioactive and possesses antimicrobial properties may address such shortcomings and improve the performance of the implant. We have sought to study the properties of combining hydroxyapatite-based nan...

Periosteum plays a pivotal role in vascularization, ossification and remodeling during the healing process of bone injury. However, there are few studies focused on the construction of artificial implants with periosteum-mimetic effect. To emulate the primary role of natural periosteum or endosteal tissues in bone regeneration, here we provide a fu...

Crystalline Hydroxyapatite (Ca10 (PO4)6(OH)2) non linear optical crystal plays a major role in biomedical applications. Crystalline Hydroxyapatite was synthesized using natural human bone sample by thermal methods. This Hydroxyapatite was characterized by Fourier Transform infra-red spectroscopy (FTIR), scanning electron microscope, UV-Vis spectros...

Few reports have evaluated the use of hydroxyapatite (HA) coating in SL-MIA-type stems in total hip arthroplasty (THA). Here, we compared early femoral bone remodeling after total hip arthroplasty using the SL-PLUS MIA stem with and without hydroxyapatite coating. From February 2012 to March 2017, 132 patients (150 hips) (HA group: 48 patients [52 ...

The aim of this study was to confirm the effect of the systemic administration of melatonin on hydroxyapatite-coated titanium (HA-Ti) implants in senile osteopenic rats. For this study 24-month-old female Sprague-Dawley rats were used. The animals were randomly divided into two groups: a control group and a melatonin group and the bilateral femurs ...
