This paper presents a superhydrophobic melamine(ME) sponge(ME-g-PLMA) prepared via high-energy radiation-induced in situ covalent grafting of long-alkyl-chain dodecyl methacrylate(LMA) onto an ME sponge for efficient oil–water separation. The obtained ME-g-PLMA sponge had an excellent pore structure with superhydrophobic(water contact angle of 154?)and superoleophilic properties. It can absorb various types of oils up to 66–168 times its mass. The ME-g-PLMA sponge can continuously separate oil slicks in water by connecting a pump or separating oil underwater with a gravity-driven *** addition, it maintained its highly hydrophobic properties even after long-term immersion in different corrosive solutions and repeated oil adsorption. The modified ME-g-PLMA sponge exhibited excellent separation properties and potential for oil spill cleanup.

Background The optimal stenting strategy for the treatment of coronary bifurcation lesions （CBLs） remains uncertain. The present study observed technical feasibility and reliability, 9-month clinical and angiographic outcomes of the modified culotte stenting （MCS） in the treatment of CBLs with drug-eluting stents. Methods A total of 34 consecutive patients with CBLs that required stenting the parent vessel （PV）, the main branch （MB） and the side branch （SB） were included. All patients were first assigned to receive MCS for CBL interventions （per MCS）, and might be switched to receive the double-kissing-crush stenting （DKS） in case of temporally acute branch occlusion （per protocol）. Results The immediate angiographic or procedural success was achieved in 33/34 （97%） lesions （patients） per MCS, 34/34 （100%） lesions （patients） per protocol with 100% successful final balloon kissing. The long-term clinical success at 9 months was 94% per MCS and 94% per protocol, only 2 patients had reoccurrence of angina but none of them needed target lesion revascularization. There were no procedure-related biomarker elevation, no in-stent thrombosis peri-procedurally and at 9-month follow-up. Quantitative coronary angiography data at 9 months showed that in-stent （6%） or in-segment （6%） binary stenosis was infrequent, and minimal lumen diameter was significantly reduced but late lumen loss was acceptable with only （0.10_-＇_-~.14） mm for PV, （0.21＋0.23） mm for MB and （0.27^-0.32） mm for SB. Conclusions MCS for treatment of CBLs that required dual-stent implantation was technically easier and safer, readily to complete final balloon kissing, and was associated with high immediate success and optimal 9-month outcomes.

The persistent epidemic of human mpox, caused by mpox virus (MPXV), raises concerns about the future spread ofMPXV and other poxviruses. MPXV is a typical zoonotic virus which can infect human and cause smallpox-likesymptoms. MPXV belongs to the Poxviridae family, which has a relatively broad host range from arthropods tovertebrates. Cross-species transmission of poxviruses among different hosts has been frequently reported andresulted in numerous epidemics. Poxviruses have a complex linear double-strand DNA genome that encodeshundreds of proteins. Genes related to the host range of poxvirus are called host range genes (HRGs). This reviewbriefly introduces the taxonomy, phylogeny and hosts of poxviruses, and then comprehensively summarizes thecurrent knowledge about the cross-species transmission of poxviruses. In particular, the HRGs of poxvirus aredescribed and their impacts on viral host range are discussed in depth. We hope that this review will provide acomprehensive perspective about the current progress of researches on cross-species transmission and HRGvariation of poxviruses, serving as a valuable reference for academic studies and disease control in the future.
