| 1 | Effect of fluence and ambient environment on the surface and structural modification of femtosecond laser irradiated Ti显示文摘Under certain conditions, ultrafast pulsed laser interaction with matter leads to the formation of self-organized conical as well as periodic surface structures(commonly reffered to as, laser induced periodic surface structures, LIPSS). The purpose of the present investigations is to explore the effect of fsec laser fluence and ambient environments(Vacuum &O_2) on the formation of LIPSS and conical structures on the Ti surface. The surface morphology was investigated by scanning electron microscope(SEM). The ablation threshold with single and multiple(N = 100) shots and the existence of an incubation effect was demonstrated by SEM investigations for both the vacuum and the O_2 environment. The phase analysis and chemical composition of the exposed targets were performed by x-ray diffraction(XRD) and energy dispersive x-ray spectroscopy(EDS), respectively. SEM investigations reveal the formation of LIPSS(nano & micro). FFT d-spacing calculations illustrate the dependence of periodicity on the fluence and ambient environment. The periodicity of nano-scale LIPSS is higher in the case of irradiation under vacuum conditions as compared to O_2. Furthermore, the O2 environment reduces the ablation threshold. XRD data reveal that for the O_2 environment, new phases(oxides of Ti) are formed. EDS analysis exhibits that after irradiation under vacuum conditions, the percentage of impurity element(Al) is reduced. The irradiation in the O_2 environment results in 15% atomic diffusion of oxygen. | Umm-i-Kalsoom Shazia Bashir Nisar Ali M Shahid Rafique Wolfgang Husinsky Chandra S R Nathala Sergey V Makarov Narjis Begum | 2016 | Chinese Physics B2016，25，1： | 2 |
| 2 | Second-generation direct-acting-antiviral hepatitis C virus treatment: Efficacy, safety, and predictors of SVR12显示文摘AIM To gather data on the antiviral efficacy and safety of second generation direct acting antiviral(DAA) treatment with respect to sustained virological response(SVR) 12 wk after conclusion of treatment, and to determine predictors of SVR12 in this setting.METHODS Two hundred and sixty patients treated with SOF combination partners PR(n = 51), R(n = 10), SMV(n = 30), DCV(n = 81), LDV(n = 73), or 3D(n = 15).144/260 were pre-treated, 89/260 had liver cirrhosis, 56/260 had portal hypertension with platelets < 100/nL, 25/260 had a MELD score ≥ 10 and 17/260 were postliver transplantation patients. 194/260 had HCV GT1, 44/260 HCV GT3.RESULTS Two hundred and forty/256(93.7%) patients achieved SVR12(m ITT); 4/260 were lost to follow-up. SVR12 rates for subgroups were: 92% for SOF/DCV, 93% for each SOF/SMV, SOF/PR, 94% for SOF/LDV, 100% for 3D, 94% for pretreated, 87% for liver cirrhosis, 82% for patients with platelets < 100/n L, 88% post-liver transplantation, 95% for GT1 a, 93% for GT1 b, 90% for GT3, 100% for GT2, 4, and 6. 12 patients suffered from relapse, 6 prematurely discontinued treatment, of which 4 died. Negative predictors of SVR12 were a platelet count < 100/nL, MELD score ≥ 10(P < 0.0001), liver cirrhosis(P = 0.005) at baseline. In Interferonfree treatment GT3 had significantly lower SVR rates than GT1(P = 0.016). Side effects were mild. CONCLUSION Excellent SVR12 rates and the favorable side-effect profile of DAA-combination therapy can be well translated into 'real-world'. Patients with advanced liver disease, signs of portal hypertension, especially with platelets < 100/n L and patients with GT3 are in special need for further research efforts to overcome comparatively higher rates of virological failure. | Christoph R Werner Julia M Schwarz Daniel P Egetemeyr Robert Beck Nisar P Malek Ulrich M Lauer Christoph P Berg | 2016 | World Journal of Gastroenterology2016，22，35： | 2 |
