[ Method] EST sequence of LDH-C gene from black-lipped pika was cloned by PCR with degenerate primers; then the full length open reading frame （ORF） and 3＇UTR sequence were cloned by RACE technique. [ Result] The full length cDNA was 1 498 bp containing an ORF of 996 bp and a 3＇UTR of 486 bp. The ORF encoded a polypeptide of 332 amino acids. The alignment of LDH-C gene ORF nucleotide sequences from different species showed that the gene was conserved even between large taxons. The phylogenic tree showed that black-lipped pika LDH-C was closer to prima- tes and artiodactyla than to rodents. [Conclusion] cDNA sequence of LDH-C gene from black-lipped pika was cloned successfully.展开更多

The following results are obtained, if (X, T) is a locally convex space, then the followings are equivalent: 1) (X, T) is a Mazur space; 2) T + (the largest locally convex topology with the same convergent sequence as T) is a compatible topology with T; 3) every sequentially open half-space in (X, T) is open. The relation between Mazur spaces and C-sequential spaces is discussed.展开更多

文摘Mazur spaces, which are locally convex spaces and every sequentially continuous linear functional over them is continuous,are characterized. The following results are obtained, if (X, T) is a locally convex space, then the followings are equivalent: 1) (X, T) is a Mazur space; 2) T + (the largest locally convex topology with the same convergent sequence as T) is a compatible topology with T; 3) every sequentially open half-space in (X, T) is open.
