查询词典 Fifty-Four

Two hundred fifty-nine F2:3 families, developed from the cross between a dent corn inbred Dan232 and a popcorn inbred N04 were evaluated for its starch content in a replicated experiments under two environments. 183 pairs SSR were selected to construct a genetic linkage map with the genetic distance of 1 762.2 cM and on average 9.6 cM every marker.

在两种环境条件下种植以普通玉米自交系丹232和爆裂玉米自交系N04为亲本构建的259个F2∶3家系群体，采用SSR标记构建了包含183个标记的爆裂玉米遗传连锁图谱，覆盖玉米基因组1 762.2 cM，标记间平均距离为9.6 cM。

A total of one hundred fifty three healthy male and female adults were entered into a six month,doubleblind clinical study designed to evaluate the effect of a dentifrice containing 0.3% triclosan and 2.0% PVM/MA copolymer in a 0.243% sodium fluoride/silica base, relative to a 0.243% sodium fluoride silica base control dentifrice on supragingival plaque accumulation and gingivitis.

本研究的目的是证实含0.3％三氯羟苯醚，2.0％PVM／MA及0.243％氟化钠以二氧化硅磨料牙膏在减少菌斑积聚和牙龈炎形成方面对中国成年人群的效果。153名健康男女分为实验组及对照组，用双盲法评价6月后临床效果。采用纳入和排除的评价标准后进行了基线检查，实验对象每日使用分配的牙膏和软毛牙刷早晚刷牙一次，3个月和6个月再次检查。检查结果表明，使用含有三氯羟苯醚－共聚体牙膏组与使用不含该成分的对照组相比，实验对象的牙菌斑、牙龈炎指数分别减少16.1％及24.3％，均有统计学显著性意义（P＜0.001）。

Methods Fifty pairs of fresh colorectal cancer and homologous normal tissues were genotyped with Identifiler Kit and the mutations generated in cancer tissues were determined. The mutation rates, the numbers of locus matched without identical allele (A0), 1 identical allele (A1), or 2 identical alleles (A2) and the number of total identical alleles IA(subscript n were calculated. Frequency distributions of A0, A1, A2 and IA were compared among CR-N group, unrelated individual pairs and full sibling pairs. Discrimination functions were established for individual identification from tumor tissues with discriminatory analysis.

用Identifiler系统对50对新鲜结直肠癌组织及其身源正常组织组进行STR分型，计算CR-N组中变异STR基因座及全不同基因座数(A0)、半相同基因座数(A1)、全相同基因座数(A2)和共有等位基因数IA(下标 n，比较CR-N组、无关个体对组和全同胞对组中上述参数的分布差异，通过判别分析建立判别函数。
