| 1 | The association of cerebrospinal fluid pressure with optic nerve head and macular vessel density显示文摘The present study aims to investigate the effect of temporary cerebrospinal fluid pressure(CSFP) reduction on optic nerve head(ONH) and macular vessel density(VD) using optical coherence tomography angiography.Forty-four eyes of 44 adults with diagnostic lumbar puncture and CSFP reduction were recruited.Thirty-two eyes of 32 healthy volunteers were controls.ONH and macular VD images were evaluated differences between baseline and after CSFP reduction.The results showed that the mean CSFP decreased from(11.6±2.1) mm Hg to(8.2±3.4) mm Hg(P<0.001).VD in the macular regions decreased significantly after CSFP reduction in the study group(all P<0.05).The control group showed no significant changes in macular VD(all P>0.05).In the study group,decreased VD in the macular parainferior region was associated with CSFP reduction(R^(2)=0.192,P=0.003),the reduction of macular VD in parafoveal(R^(2)=0.098,P=0.018),parainferior(R^(2)=0.104,P=0.021),parasuperior(R^(2)=0.059,P=0.058),paranasal(R^(2)=0.057,P=0.042),paratemporal(R^(2)=0.079,P=0.026) was associated with mean ocular perfusion pressure decrease following CSFP reduction.ONH vessel density did not differ after CSFP reduction(all P>0.05).In conclusion,macular vessel density decreased in association with CSFP reduction.Retinal vessel density in the macular region is more sensitive than that in peripapillary region after CSFP reduction. | Xiangxiang Liu Mohamed M.Khodeiry Danting Lin Yunxiao Sun Qing Zhang Jiawei Wang Richard K.Lee Ningli Wang | 2022 | Science China(Life Sciences)2022，65，6： | 3 |
| 2 | Construction of interfacial dynamic bonds for high performance lignin/polymer biocomposites显示文摘Lignin is the largest natural aromatic biopolymer,but usually treated as industrial biomass waste.The development of lignin/polymer biocomposites can promote the high value utilization of lignin and the greening of polymers.However,the weak interfacial interaction between industrial lignin and polymer induces poor compatibility and serious agglomeration in polymer owing to the strong intermolecular force of lignin.As such,it is extremely difficult to prepare high performance lignin/polymer biocomposites.Recently,we proposed the strategy of in situ construction of interfacial dynamic bonds in lignin/polymer composites.By taking advantage of the abundant oxygen-containing polar groups of lignin,we inserted dynamic bonding connection such as hydrogen bonds and coordination bonds into the interphase between lignin and the polymer matrix to improve the interfacial interactions.Meanwhile,the natural amphiphilic structure characteristics of lignin were utilized to construct the hierarchical nanophase separation structure in lignin/polymer composites.The persistent problems of poor dispersity and interfacial compatibility of lignin in the polymer matrix were effectively solved.The lignin-modified polymer composites achieved simultaneously enhanced strength and toughness.This concise review systematically summarized the recent research progress of our group toward building high-performance lignin/polymer biocomposites through the design of interfacial dynamic bonds(hydrogen bonds,coordination bonds,and dynamic covalent bonds)between lignin and different polymer systems(polar plastics,rubber,polyurethane,hydrogels,and other polymers).Finally,the future development direction,main challenges,and potential solutions of lignin application in polymers were presented. | Jianbin Mo Haixu Wang Mengzhen Yan Jianhua Huang Rui Li Danting Sun Junjie Lei Xueqing Qiu Weifeng Liu | 2023 | Frontiers of Chemical Science and Engineering2023，17，10： | 0 |
| 3 | ORP8 acts as a lipophagy receptor to mediate lipid droplet turnover显示文摘Lipophagy,the selective engulfment of lipid droplets(LDs)by autophagosomes for lysosomal degradation,is critical to lipid and energy homeostasis.Here we show that the lipid transfer protein ORP8 is located on LDs and mediates the encapsulation of LDs by autophagosomal membranes.This function of oRP8 is independent of its lipid transporter activity and is achieved through direct interaction with phagophore-anchored LC3/GABARAPs.Upon lipophagy induction,ORP8 has increased localization on LDs and is phosphorylated by AMPK,thereby enhancing its affinity for LC3/GABARAPs.Deletion of ORP8 or interruption of ORP8-LC3/GABARAP interaction results in accumulation of LDs and increased intracellular triglyceride.Overexpression of ORP8 alleviates LD and triglyceride deposition in the liver of ob/ob mice,and Osbpl8 mice exhibit liver lipid clearance defects.Our results suggest that ORP8 is a lipophagy receptor that plays a key role in cellular lipid metabolism. | Maomao Pui Wenhui Zheng Hongtao Zhang Wei Wan Chao Peng Xuebo Chen Xinchang Liu Zizhen Xu Tianhua Zhoul Qiming Sun Dante Neculai Wei Liu | 2023 | Protein & Cell2023，14，9： | 0 |
