| 1 | Stroke mechanisms and outcomes of isolated symptomatic basilar artery stenosis显示文摘background While diffuse atherosclerotic disease affecting the posterior circulation has been described extensively,the prevalence,natural history and angiographic characteristics of isolated symptomatic basilar artery stenosis(ISBAS)remain unknown.Methods We reviewed our prospective institutional database to identify patients with≥50% symptomatic basilar artery(BA)stenosis without significant atherosclerotic burden in the vertebral or posterior cerebral arteries.Stroke mechanism,collateral circulation,and degree and length of stenosis were analysed.The primary outcome was time from index event to new transient ischaemic attack(TIA),acute ischaemic stroke(AIS)or death.Other outcome variables included modified Rankin Scale(mRS)score on discharge and last follow-up.results Of 6369 patients with AIS/TIA,91(1.43%)had ISBAS.Seventy-three(80.2%)patients presented with AIS and 18(19.8%)with TIA.Twenty-nine(31.9%)were women and the median age was 66.8±13.6 years.The mean follow-up time was 2.7 years.The most common stroke mechanism was artery-to artery thromboembolism(45.2%),followed by perforator occlusion(28.7%)and flow-dependent/hypoperfusion(15.1%).The percentage of stenosis was lower in patients who had favourable outcome compared with those with mRS 3-6 on discharge(78.3±14.3 vs 86.9±14.5,p=0.007).Kaplan-Meier curves showed higher recurrence/death rates in patients with≥80% stenosis,mid-basilar location and poor collateral circulation.Approximately 13% of patients with ISBAS presented with complete BA occlusion.Conclusion ISBAS is an uncommon(1.43%)cause of TIA and AIS.Men in their 60s are mostly affected,and artery-to artery embolism is the most common stroke mechanism.Mid-basilar location,≥80% stenosis and poor collateral circulation are important factors associated with worse prognosis. | Edgar A Samaniego Amir Shaban Santiago Ortega-Gutierrez Jorge A Roa David M Hasan Colin Derdeyn Biyue Dai Harold Adams Enrique Leira | 2019 | Stroke & Vascular Neurology2019，4，4： | 10 |
| 2 | Warm Deformation of Low Carbon Steel Using Forward Extrusion-Equal Channel Angular Pressing Technique显示文摘A combination of extrusion and equal channel angular pressing (ECAP) was used to deform a plain low carbon steel. This process consists of two successive deformations by extrusion and ECAP in a single die (Ex-ECAP). Cylindrical samples were heated to predefined temperatures (650 and 850 ℃) and then pressed through a die channel with crosshead speed of 10 mm/s. Microstructure and resultant mechanical properties of processed material were studied. The results showed that pressing temperature has a significant effect on the resultant microstructure. While at 650 ℃, the cold worked structure with elongated ferrite grains were obtained, and at 850 ℃ the microstructure consisted of elongated ferrite grains and very fine grains at their boundaries as a consequence of continuous dynamic recrystallization (CDRX) of ferrite phase. Also at 850 ℃, a particular microstructure consisted of cold worked ferrite and static recrystallized grains on shear bands was obtained. | B Eghbali M Shaban | 2013 | Journal of Iron and Steel Research(International)2013，20，2： | 9 |
