晓观天下·之三十四 真正的“国际秩序修正主义国家”,不在太平洋西岸

正何为"国际修正主义"最近,"修正主义"这个似乎只有老几辈中国人才印象深刻的词重新频繁映入我们眼帘。2017年12月18日特朗普政府提交国会的首份《美国国家安全战略报告》在将中国定性为美国的"战略竞争者""利益挑战者"的同时,也将中国称作"国际秩序的修正主义国家"。在很多中国人的印象中,在对外关系中最激烈使用"修正主义"这个词,还是跟改革开放前那个晦暗年代中发生的中苏论战联系在一起的。

Molecular cloning and expression of interleukin Ibeta (IL-1β) from red seabream (Pagrus major)

The interleukin 1β (IL-1β) cDNA was cloned from the red seabream (Pagrus major) by homology cloning strategy. A cDNA fragment was amplified by PCR using two degenerated primers, which were designed according to the conserved regions of other known IL-1β sequences, and elongated by 3' ends and 5' ends RACE PCR to get the full length coding sequence of red seabream IL-1β (RS IL-1β). The sequence contained 1252 nucleotides that included a 5' untranslated region (UTR) of 84bp, a 3' UTR of 410 bp and an open reading frame (ORF) of 759 nucleotides which could be translated into a putative peptide of 253 amino acids with molecular weight of 28.6 kD and putative isoelectric point pI of 5.29. The deduced peptide contained two potential N-glycosylation sites and an identifiable IL1 family signature, but lacked the signal peptide and the clear ICE cut site, which were common in other nonmammalian IL-1β genes. The RS IL-1β had the highest homology with piscine IL-1β according to phylogenetic tree analysis.
