Identification of the Angel -related elements in cyprinid fishes and their phylogenetic implications

Angel-related element belongs to the family of miniature inverted-repeat transposable elements (MITEs). In this paper we report the identification of an Angel- related element in the series Leuciscini of cyprinid fishes, which is located in the second intron of the growth hormone (GH) gene. We have also found that this element is absent in orthologous locus in the series Barbini of cyprinid fishes, that provides new evidence for the monophyly of the series Leuciscini. The insertion of Angel -related element into the GH gene might take place in the common ancestor of the series Leuciscini after its divergence from the series Barbini. The high sequence divergence and relatively broad species distribution of Angel-related elements implies that they might be ancient transposons which appeared about 26 million years ago.     

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.

以智慧对抗蛮力的技巧—Human VS Orc战术浅谈

关于兽人对人类的对战,排除诸如雇佣兵以及过量召唤物品这种影响平衡性的因素后,人类一般是处于比较被动状态的,往往顶不住中期的进攻而导致失败。纵观ORC的各种战术,可以发现胜利的往往是一波进攻将对手彻底打垮,单矿的兽人总是通过采取偷偷暴克制对手的单位而取得决定性的优势的。我们很难发现对手的意图,因为对手很好的将我们牵制在家中。     

The Challenging Topics and Future Directions of the Research in Limnology and Watershed Sciences

Based on reviewing the problems in limnology and watershed sciences in meeting the national demands and the development of theories and methodology, this paper proposed some challenging topics to the sciences, covering the process of lake evolution and the quantitative analysis of human impacts, in -lake nutrient cycling an biogeo-chemical process, the process and mechanisms of material flow in lake-watershed system, digital watershed and the modeling of the surface process of lake -watershed, and ecosystem health and scientific management of lake-watershed.
