| 1 | The resurgent landscape of xenotransplantation of pig organs in nonhuman primates显示文摘Organ shortage is a major bottleneck in allotransplantation and causes many wait-listed patients to die or become too sick for transplantation.Genetically engineered pigs have been discussed as a potential alternative to allogeneic donor organs.Although xenotransplantation of pig-derived organs in nonhuman primates(NHPs)has shown sequential advances in recent years,there are still underlying problems that need to be completely addressed before clinical applications,including(i)acute humoral xenograft rejection;(ii)acute cellular rejection;(iii)dysregulation of coagulation and inflammation;(iv)physiological incompatibility;and(v)cross-species infection.Moreover,various genetic modifications to the pig donor need to be fully characterized,with the aim of identifying the ideal transgene combination for upcoming clinical trials.In addition,suitable pretransplant screening methods need to be confirmed for optimal donor-recipient matching,ensuring a good outcome from xenotransplantation.Herein,we summarize the understanding of organ xenotransplantation in pigs-to-NHPs and highlight the current status and recent progress in extending the survival time of pig xenografts and recipients.We also discuss practical strategies for overcoming the obstacles to xenotransplantation mentioned above to further advance transplantation of pig organs in the clinic. | Xuan Zhang Quancheng Wang Jingjun Zhao Xiao Li Wei Peng Zhaoxu Yang Zhibin Lin Long Yang Rui Ding Kaishan Tao Kefeng Dou | 2021 | Science China(Life Sciences)2021，64，5： | 10 |
| 2 | Hierarchical coupling effect in hollow Ni/NiFe2O4-CNTs microsphere via spray-drying for enhanced oxygen evolution electrocatalysis显示文摘Design and fabrication of cost-effective transition metal and their oxides-based nanocomposites are of paramount significance for metal-air batteries and water-splitting.However,the traditional optimized designs for nanostructure are complicated,low-efficient and underperform for wide-scale applications.Herein,a novel hierarchical framework of hollow Ni/NiFe2O4-CNTs compositemicrosphere forcibly-assembled by zero-dimensional(OD)Ni/NiFo204 nanoparticle(<16 nm)and one-dimensional(1D)self-supporting CNTs was fabricated successfully.Benefitted from the unique nanostructure,such monohybrids can achieve remarkable oxygen evolution reaction(OER)performance in alkaline media with a low overpotential and superior durability,which exceeds most of the commercial catalysts based on IrO/RuO2 or other non-noble metal nanomaterials.The enhanced OER performance of Ni/NiFe2OA-CNTs composite is mainly ascribed to the increased catalytic activity and the optimized conductivity induced by the effects of strong hierarchical coupling and charge transfers between CNTs and Ni/NiFe204 nanoparticles.These effects are greatly boosted by the polarized heterojunction interfaces confirmed by electron holography.The density functional theory(DFT)calculation indicates the epitaxial Ni further enriches the intrinsic electrons contents of NiFe204 and thus accelerates absorption/desorption kinetics of OER intermediates.This work hereby paves a facile route to construct the hollow composite microsphere with excellent OER electrocatalytic activity based on non-noble metal oxide/CNTs. | Xuefeng Yu Guanyu Chen Yizhe Wang Jiwei Liu Ke Pei Yunhao Zhao Wenbin You Lei Wang Jie Zhang Linshen Xing Jingjun Ding Guangzhou Ding Min Wang Renchao Che | 2020 | Nano Research2020，13，2： | 3 |
