| 1 | Microstructure and properties of porous Si_(3)N_(4)ceramics by gelcasting-self-propagating high-temperature synthesis(SHS)显示文摘Porous silicon nitride ceramics have attracted a considerable attention due to their excellent overall performance,but poor porosity homogeneity and structural shrinkage induced by prolonged high temperature sintering limit its further application.Herein,as a three-in-one solution for the above issues,for the first time we develop a novel approach that integrates the merits of gelcasting-SHS(self-propagating high-temperature synthesis)to prepare porous Si_(3)N_(4)ceramics to simultaneously achieve high porosity,high strength,high toughness,and low thermal conductivity across a wide temperature range.By regulating the solid content,porous Si_(3)N_(4)ceramics with homogeneous pore structure are obtained,where the pore size falls inbetween 1.61 and 4.41 pm,and the elongated grains are interlaced and interlocked to form micron-sized coherent interconnected pores.At the same time,porous Si_(3)N_(4)ceramics with porosity of 67.83%to 78.03%are obtained,where the compressive strength reaches 11.79 to 47.75 MPa and fracture toughness reaches 1.20 to 6.71 MPa-m1/2. | Shile CHEN Liang WANG Gang HE Jiangtao LI Chang-An WANG | 2022 | Journal of Advanced Ceramics2022，11，1： | 2 |
| 2 | Artesunate and Dihydroartemisinin Inhibit Rabies Virus Replication显示文摘Rabies is caused by infection of rabies virus(RABV)and remains a serious threat to the global public health.Except for the requirement for cold chain and high cost of human rabies immune globulin,no small molecule drugs are currently available for clinical treatment of rabies.So,it is of great importance to identify novel compounds that can effectively inhibit RABV infection.Artesunate(ART)and dihydroartemisinin(DHA),two derivatives of artemisinin,are widely used for treatment of malaria in adults and children,showing high safety.In this study,we found that both ART and DHA were able to inhibit RABV replication in host cells at a low concentration(0.1μmol/L).The antiviral effects of ART and DHA were independent of viral strains and cell lines.Pre-treatment with ART or DHA for 2 h in vitro did not affect the viral replication in host cells,implying that ART and DHA neither reduced the viability of RABV directly nor inhibited the binding and entrance of the virus to host cells.Further studies revealed that ART and DHA inhibited RABV genomic RNA synthesis and viral gene transcription.Treatment with ART or DHA(5 mg/kg)by intramuscular injection improved,to some extent,the survival rate of RABV-challenged mice.Combination treatment with derivatives of artemisinin and mannitol significantly improved the survival rate of RABV-challenged mice.The results suggest that ART and DHA have a great potential to be explored as new anti-rabies agents for treatment of rabies. | Jun Luo Yue Zhang Yang Wang Qing Liu Jiesen Li Hongling He Yongwen Luo Shile Huang Xiaofeng Guo | 2021 | Virologica Sinica2021，36，4： | 2 |
