The gonadotropin releasing hormone receptor gene was studied as a candidate gene for the prolificacy of Small Tail Han sheep. Eight pairs of primers were designed to detect single nucleotide polymorphisms of exon 1, exon 2 and exon 3 of GnRHR gene in both high fecundity breeds and low fecundity breeds (South African Mutton Merino, Corriedale and Chinese Merino sheep) by PCR-SSCP. Only the products amplified by primers P4 and P7 displayed polymorphisms.

RESULTS: In univariate analysis, six genes were significantly associated with time to recurrence, and 10 with overall survival.

结果：在单变量分析中，6个基因与复发时间具有显著的相关性；同时10个基因与总存活数具有显著的相关性。

Seven major bacterial isolates were obtained and purified. Their 16S rRNA genes were amplified by PCR for sequencing and their identities were determined with homology comparisons. Five of the seven isolates belong to Actinomycetales including Kocuria KD139, Rhodococcus KD140, Rhodococcus KD142, Arthrobacter KD230, and Arthrobacter KD232; one is classified as Bacillus d KD178; and another one as Stenotrophomonas KD237. The phylogenetic tree was also constructed based on the analysis of 16S rRNA gene sequences.

通过对分离菌株的16S rRNA基因序列进行分析，发现其中5株细菌分别属于放线菌目的考克氏菌属(KD139)、红球菌属(KD140和KD142)和节杆菌属(KD230和KD232)， 1株细菌属于杆菌目的芽胞杆菌d属(KD178)，另外1株细菌属于黄色单孢菌目的寡食单胞菌属(KD237)；同时我们构建了系统进化树，确定分离菌株的相对进化地位。

RESULTS. A total of 1224 twins (690 monozygotic and 534 dizygotic ) between 18 and 86 years of age were recruited into the GEM study. A total of 96 twins (96/347 = 27.7%) comprising 50 MZ and 46 DZ twins were first prescribed optical correction for myopia at the age of 18 years or older.
