| 1 | Differences in left and right carotid plaque vulnerability in patients with bilateral carotid plaques:a CARE-II study显示文摘Background and purpose Atherosclerosis is a very complex process influenced by various systemic and local factors.Therefore,in patients with bilateral carotid plaques(BCPs),there may be differences in carotid plaque vulnerability between the sides.We aimed to investigate the differences in BCP characteristics in patients with BCPs using magnetic resonance vessel wall imaging(MR-VWI).Methods Participants with BCPs were selected for subanalysis from a multicentre study of Chinese Atherosclerosis Risk Evaluation II.We measured carotid plaque burden,identified each plaque component and measured their volume or area bilaterally on MR-VWI.Paired comparisons of the burden and components of BCPs were performed.Results In all,540 patients with BCPs were eligible for analysis.Compared with the right carotid artery(CA),larger mean lumen area(p<0.001),larger mean wall area(p=0.025),larger mean total vessel area(p<0.001)and smaller normalised wall index(p=0.006)were found in the left CA.Regarding plaque components,only the prevalence of lipid-rich necrotic core(LRNC)in the left CA was higher(p=0.026).For patients with a vulnerable plaque component coexisting on both sides,only the intraplaque haemorrhage(IPH)volume(p=0.011)was significantly greater in the left CA than in the right CA.Conclusions There were asymmetries in plaque growth and evolution between BCPs.The left carotid plaques were more likely to have larger plaque burden,higher prevalence of LRNC and greater IPH volume,which may contribute to the lateralisation of ischaemic stroke in the cerebral hemispheres. | Sai Shao Honglu Shi Guangbin Wang Rui Li Qinjian Sun Bin Yao Hiroko Watase Daniel S Hippe Chun Yuan Xihai Zhao | 2023 | Stroke & Vascular Neurology2023，8，4： | 1 |
| 2 | 3D printing of high-precision and ferromagnetic functional devices显示文摘The development of projection-based stereolithography additive manufacturing techniques and magnetic photosensitive resins has provided a powerful approach to fabricate miniaturized magnetic functional devices with complex three-dimensional spatial structures.However,the present magnetic photosensitive resins face great challenges in the trade-off between high ferromagnetism and excellent printing quality.To address these challenges,we develop a novel NdFeB-Fe_(3)O_(4) magnetic photosensitive resin comprising 20 wt.%solid loading of magnetic particles,which can be used to fabricate high-precision and ferromagnetic functional devices via micro-continuous liquid interface production process.This resin combining ferromagnetic NdFeB microparticles and strongly absorbing Fe_(3)O_(4) nanoparticles is able to provide ferromagnetic capabilities and excellent printing quality simultaneously compared to both existing soft and hard magnetic photosensitive resins.The established penetration depth model reveals the effect of particle size,solid loading,and absorbance on the curing characteristics of magnetic photosensitive resin.A high-precision forming and ferromagnetic capability of the NdFeB-Fe_(3)O_(4) magnetic photosensitive resin are comprehensively demonstrated.It is found that the photosensitive resin(NdFeB:Fe_(3)O_(4)=1:1)can print samples with sub-40μm fine features,reduced by 87%compared to existing hard magnetic photosensitive resin,and exhibits significantly enhanced coercivity and remanence in comparison with existing soft magnetic photosensitive resins,showing by an increase of 24 times and 6 times,respectively.The reported NdFeB-Fe_(3)O_(4) magnetic photosensitive resin is anticipated to provide a new functional material for the design and manufacture of next-generation micro-robotics,electromagnetic sensor,and magneto-thermal devices. | Zhiyuan Huang Guangbin Shao Dekai Zhou Xinghong Deng Jing Qiao Longqiu Li | 2023 | International Journal of Extreme Manufacturing2023，5，3： | 0 |
| 3 | Porous bio-high entropy alloy scaffolds fabricated by direct ink writing显示文摘Porous tantalum-titanium-niobium-zirconium(Ta-Ti-Nb-Zr)bio-high entropy alloy(bioHEA)scaffolds are fabricated using direct ink writing 3D printing technology in this study.A composite ink is prepared using four metal powders as raw materials:Ta,Ti,Nb and Zr.Ink extrusion is used to build 3D scaf-folds with interconnected porous structures at room temperature,which are then sintered in a vacuum environment.The interdiffusion of metal elements yields porous bioHEA scaffolds with a body-centered cubic(BCC)structure.The fabricated scaffolds have uniform compositions with a significant alloying ef-fect and good biocompatibility.The scaffolds have a compressive strength of 70.08-149.95 MPa and an elastic modulus of 0.18-0.64 GPa,indicating that the mechanical properties can be controlled over a wide range.The scaffolds have a compressive strength close to that of human cortical bone and thus meet the requirements for porous structure characteristics and biological and mechanical properties of orthopedic implants. | Guangbin Zhao Xiaoxi Shao Qingxian Zhang Yanlong Wu Yaning Wang Xu Chen Hang Tian Yaxiong Liu Yanpu Liu Bingheng Lu | 2023 | Journal of Materials Science & Technology2023，，26： | 0 |
