Nanoparticles of Zn1-xCuxO system with nominal compositions x = 0.0, 0.01, 0.02 and 0.03 were prepared by co-precipitation method at room temperature. Structural, morphological, optical and chemical species of grown crystals were investigated by X-ray diffraction (XRD) technique, Scanning Electron Microscopy (SEM), UV-visible and FTIR spectroscopy, respectively. XRD analysis confirms that all samples have hexagonal structure with no impurity phases which suggest that Cu ion successfully incorporated into the regular ZnO crystal structure. The lattice parameters, volume of unit cell, X-ray density, atomic packing fraction, c/a ratio, and grain size were calculated from XRD pattern of pure and Cu doped ZnO samples and it was found that the grain size was in the range of 23 nm to 29 nm. The strain in pure and Cu doped ZnO samples was calculated by W-H analysis. Optical properties of Zn1-xCuxO samples were studied by using UV-vis spectrophotometer. Optical absorption spectra show that the band gap decreases with increasing Cu contents. The functional group and chemical interactions of Zn1-xCuxO samples were also determined at various peaks using FTIR data and observed that the functional groups corresponding to the Zn-O bands in the samples. The photocatalytic activities of the samples were investigated by oxidation of methylene blue under UV light illumination in batch reactor. The scavenger study was carried out to find out main reactive species responsible for the degradation of dyes.

Acute pancreatitis is a rare complication of interferon (IFN) and ribavirin (RbV) therapy. The aim of this study was to determine the incidence, clinical presentation, and outcome of acute pancreatitis in patients with chronic hepatitis C virus (HCV)-infection treated with IFN and RbV combination therapy. We conducted a retrospective review of 1706 HCV-infected patients treated with IFN α-2b and RbV. The diagnosis of drug-induced acute pancreatitis was made based on the presence of epigastric pain, elevated amylase and lipase levels, and the absence of other identifiable causes of pancreatitis. Acute pancreatitis was diagnosed in 7 of 1706 HCV-infected patients (0.4% ; 95% CI,0.2 to 0.8% ) who were treated with IFN α-2b and RbV. The mean age of the patients (four males and three females) was 51.4 ± 4.7 years and the median duration of therapy prior to development of pancreatitis was 12.0 weeks (range, 4.0-21.0 weeks). All patients presented with epigastric pain associated with nausea, vomiting, and/or fever. The median amylase and lipase values at the time of diagnosis of pancreatitis were 330.0U/L (range, 182.0-1813.0 U/L) and 500.0 U/L (range, 171.0-2778.0 U/L), respectively. IFN and RbV were discontinued in all patients at the time of diagnosis and six of the seven patients were hospitalized; one patient refused hospital *** resolved in all seven patients and none of these individuals had recurrent pancreatitis during a median follow-up of 18.0 months (range, 3.0-27.0 months). In conclusion,IFN and RbV combination therapy is a potential cause of drug-induced pancreatitis in patients with chronic HCV. In these individuals, pancreatitis is often severe enough to warrant hospital admission, although symptoms resolve promptly after discontinuation of antiviral therapy.

纳米复合材料是一种在三维空间中至少有一维处于纳米尺度范围(<100nm)的材料。在聚合物基体中适当加入纳米粒子,可显著提高其性能。通过这种方法获得的材料就可称作为某种纳米填料的高分子复合材料。通过控制加入复合材料中的纳米粒子的结构,就可以得到具有新的物理机械性能和未填充材料所不具备的特性的材料,如阻燃性、加速生物降解性等。
