1Safety of endovascular therapy for symptomatic intracranial artery stenosis:a national prospective registry显示文摘Introduction The safety outcomes of endovascular therapy for intracranial artery stenosis in a real-world stetting are largely unknown.The Clinical Registration Trial of Intracranial Stenting for Patients with Symptomatic Intracranial Artery Stenosis(CRTICAS)was a prospective,multicentre,real-world registry designed to assess these outcomes and the impact of centre experience.Methods 1140 severe,symptomatic intracranial arterial stenosis(ICAS)patients treated with endovascular therapy were included from 26 centres,further divided into three groups according to the annual centre volume of intracranial angioplasty and stent placement procedures over 2 years:(1)high volume for≥25 cases/year;(2)moderate volume for 10–25 cases/year and(3)low volume for<10 cases/year.Results The rate of 30-day stroke,transient ischaemic attack or death was 9.7%(111),with 5.4%,21.1%and 9.7%in high-volume,moderate-volume and low-volume centres,respectively(p<0.05).Multivariable logistic regression confirmed high-volume centres had a significantly lower primary endpoint compared with moderate-volume centres(OR=0.187,95%CI:0.056 to 0.627;p≤0.0001),while moderate-volume and low-volume centres showed no significant difference(p=0.8456).Conclusion Compared with the preceding randomised controlled trials,this real-world,prospective,multicentre registry shows a lower complication rate of endovascular treatment for symptomatic ICAS.Non-uniform utilisation in endovascular technology,institutional experience and patient selection in different volumes of centres may have an impact on overall safety of this treatment.Yabing Wang Tao Wang Adam Andrew Dmytriw Kun Yang Liqun Jiao Huaizhang Shi Jie Lu Tianxiao Li Yujie Huang Zhenwei Zhao Wei Wu Jieqing Wan Qinjian Sun Bo Hong Yongli Li Liyong Zhang Jianfeng Chu Qiong Cheng Yiling Cai Pengfei Wang Qi Luo Hua Yang Baijing Dong Yang Zhang Jun Zhao Zuoquan Chen Wei Li Xiaoxin Bai Weiwen He Xueli Cai Maimai Ti Osama O Zaidat 2022Stroke & Vascular Neurology2022,7,2:3
2Impact of the Travelling Magnetic Field on the Metallic Impurities During the Crystallization of Photovoltaic Silicon显示文摘Silicon is the most extensively studied semiconductor mainly owing to its wide applicability in the photovoltaic solar cell industry.However the qualily of Si photovoltaic cells depends on the purity of the material and on the grain structure of the ingot from which the wafers are cutting.The electrical performance of such materials,i.e.mainly their minority carrier lifetime,is closely related to metal impurities present in the feedstock or introduced during crystal growth.These impurities strongly interact with existing crystal defects to form complexes,accumulate at dislocations or grain boundaries in different forms,or even form silieide precipitates,which simultaneously contain several metal impurities.In such a context,it is necessary to control the segregation of impurities especially metallic in the grown ingot in order to optimize the cell properties as a function of the raw material purity.A new Bridgman set-up is developed in order to study the crystallization of photovoltaic Si under independently controlled solidification parameters growth rate,thermal gradient,purity and convection.Convection,either natural or forced,plays a very important role during the crystallization.Its intensity and flow pattern affect heat and mass transfer and,consequently,macrostructure and segregation in a solidified ingot.Here the convection can be controlled by a travelling magnetic field in order to homogenize or segregate the rejected impurities such as metallic elements.The effects of the magnetic field intensity and frequency on the segregation and crystalline structure will be presented.Kader Zaidat Mircea Cablea Abdallah Nouri Ghatfan Hassan Bachir Saadi Olga.Budenkova Annie.Gagnoud Yves.Delannoy 2012Journal of Iron and Steel Research(International)2012,19,S1:2
