Abstract

Needle-like nanocarbonated hydroxyapatite (CHA) powders were prepared by hydrothermal method using Ca(NO3)2, (NH4)3PO4 and urea as reagents. Element analyse (EMA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and thermogravimetry differential thermogravimetry (TG-DTA) were used to characterise the crystalline phase, microstructure, chemical composition, morphology and thermal stability of CHA. The results show that AB type CHA can be obtained through this method. The carbonate content and the ratio of length to diameter of CHA can be adjusted by controlling the concentration of urea. The results show that CO32−incorporated into the apatite structure has an influence on the properties of CHA, such as the morphology and the size of crystal grain, the lattice parameters and the unit cell volume and the crystallisation degree and the stability.

Abstract

Spherical nano-hydroxyapatite (HA) was synthesised successfully. Ca(NO3)2˙4H2O and (NH4)3PO4˙3H2O were used as reagents and polyvinylpyrrolidone (PVP) as template. The crystal phase, chemical composition, microstructure of the obtained HA were characterised by X-ray powder diffraction analysis, Fourier transform infrared spectroscopy, X-ray fluorescence spectrometry, thermogravimetric analysers microcomputer differential thermal analysers and transmission electron microscopy. The results show that the concentration of PVP significantly affects the morphologies of the nanometre HA. Spherical nano-hydroxyapatite particle with diameter of 30–50 nm can be synthesised using PVP of a certain concentration (0˙5–5%) as template. The crystallinity of HA decreases continuously as the PVP content increases. Spherical apatite crystal forms because of a high affinity between HA and PVP.

Abstract

Based on the principles of biomineralisation, spindle shaped hydroxyapatites (HA) were synthesised through the biomimetic method with chitosan (CS) as template. The microstructure, chemical composition and thermal behaviour were characterised by means of X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy and thermogravimetry differential thermal analysis (TGDTA) respectively. The results show that the spindle shaped nanoHA, 30–40 nm in length and 7–8 nm in width, were synthesised with 0·5 wt-%CS as template in 6% (v/v) hydrogen peroxide solution for 7 days. The crystallinity of samples increased with the aging time. TGDTA analyses show that the HA powders synthesised with CS as template contain CS molecules and have good thermal stability up to 800°C.

Abstract

Background: The importance of intravascular ultrasound (IVUS)-guided stenting of the unprotected left main coronary artery (ULMCA) remains controversial and has not been fully studied in the subset of patients with ULMCA. This study evaluated the clinical outcome of IVUS-guided stenting using a drug-eluting stent for ULMCA.Methods: A total of 1,016 consecutive patients with ULMCA stenosis who underwent drug-eluting stent implantation from January 2006 to December 2011 were prospectively registered. The primary endpoint of this nonrandomized registry was the rate of one-year major adverse cardiac events (MACE, including cardiac death, myocardial infarction, and target vessel revascularization). Stent thrombosis served as the safety endpoint. Propensity score matching was used to calculate the adjusted event rate.Results: The unadjusted one-year MACE rate was 14.8% in the IVUS-guided group (n=337, 33.2%), significantly different from the 27.7% (P<0.001) in the angiography-guided group (n=679, 66.8%). After propensity score matching, 291 paired patients were matched between the two groups, and the difference in one-year MACE between IVUS-guided (16.2%) versus angiography-guided (24.4%) groups was still significant (P=0.014), mainly driven by decreased rates of cardiac death (1.7%) and target vessel revascularization (3.4%) in the IVUS-guided group when compared with 5.2% (P=0.023) and 10.0% (P=0.002) in the angiography-guided group, respectively. Although it did not reach significance (P=0.075), the adjusted one-year rate of stent thrombosis in the angiography-guided group was higher than in the IVUS-guided group.Conclusion: Compared with angiography guidance, IVUS-guided treatment of ULMCA using a drug-eluting stent was associated with a significant reduction of one-year cardiac death and target vessel revascularization, resulting in less frequent one-year MACE after propensity score matching.

Abstract

The solid solution crystals, Bi4(GexS1-x)3O12 (BGSO) with x = 0, 0.05, and 0.15, have been grown by the modified vertical Bridgman method. The as-grown crystals show 80% of transmittance with an absorption edge of 285 nm. The relative light yields of BGSO crystals are found to be 7.2%, 6.3%, and 4.2% of CsI(Tl) crystal for x = 0, 0.05, and 0.15, respectively. The energy resolutions of these crystals are 18.9%, 21.3%, and 24.7%, respectively, with PMT for 662 keV gamma rays at room temperature when exposed to 137Cs-ray. The scintillation performance of BGSO crystals clearly deteriorates with the increase of Ge content. However, the appropriate number of germanium ions doped to BSO crystal can improve its crystallization behavior and effectively restrain component segregation. It is expected that large size crystals of BGSO will be grown and applied to the dual readout calorimeter in the nearest future. [ABSTRACT FROM AUTHOR]
