Silver doped hydroxyapatite [AgHAp, Ca10−xAg(PO4)6(OH)2], due to its antimicrobial properties, is an advantageous material be used for various coatings. The AgHAp thin films with xAg = 0.05 and 0.1 were achieved using the spin-coating method. resulting samples examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force (AFM), Fourier transform infrared spectroscopy (FT...

In this study, the cerium-doped hydroxyapatite (Ca10−xCex(PO4)6(OH)2 with xCe = 0.1, 10Ce-HAp) coatings obtained by spin coating method were presented for first time. The stability of 10Ce-HAp suspension particles used in preparation was evaluated ultrasonic studies, transmission electron microscopy (TEM), X-ray diffraction (XRD), and scanning (SEM). surface morphology studied SEM atomic force ...

In this study, the relationship among four species of Polygonum (including P. hyrcanicum (three samples), P. persicaria, P. avicular, and P. hydropiper) was investigated by GC profiling. Furthermore, the major compounds of the ethylic ether extract of P. hyrcanicum were identified by GC/MS as: α-bisabolol (17.5%), cedrol (15.9%), sesquisabinene hydra...

Nocardioides aromaticivorans IC177 is a gram-positive carbazole degrader. The genes encoding carbazole degradation (car genes) were cloned into a cosmid clone and sequenced partially to reveal 19 open reading frames. The car genes were clustered into the carAaCBaBbAcAd and carDFE gene clusters, encoding the enzymes responsible for the degradation of carbazole to anthranilate and 2-hydroxypenta-...

The suitability of CaCl2 as a mineralizing agent in the synthesis low-temperature C2S-cement clinker from wastes autoclaved aerated concrete was investigated. As chlorellestadite is potential host mineral for immobilization chlorine, formation conditions highest joint content and C2S were studied samples with different sulfate contents. Oven experiments conducted at temperatures between 700 120...

Introduction: The present study was conducted to evaluate the effect of Chlorogenic Acid (CA) and Diazepam (DZP) on epileptic complication that induced by repetitive intra-peritoneal injections of Pentylenetetrazle (PTZ) in aged rats.   Methods: Twenty-four month-old male Wistar rats (age > 12 months, 300-350 g) were divided in 4 experimental groups. Animal in control group (PTZ + Vehicle) re...
