转移酶

An approach has been developed to genotype point mutations using ligase-mediated induced fluorescence resonance energy transfer.

发展了一种基于连接酶介导的诱导荧光共振能量转移技术用于基因点突变的准确快速检测方法。

Methods PCR screening and DNA sequence were used to determine the drug resistance genes associated with class I integron in 4 clinical strains of P.aeruginosa. The resistance genes were located by conjugated transfer experiments and the conjugations were studied by PCR method.

整合子通过整合酶从环境中捕获耐药基因盒，并将耐药基因盒组装在一起，形成巨大的耐药基因多基因座；同时整合子及耐药基因盒可借助转化、转导及接合等方式在细菌中转移，使耐药基因广泛传播。

Study shows that strengthening body resistance and archaeus herbs have many effects,such as improving and adjusting immunity function,protecting bone marrow,improving haematogenesis function,raising digest and absorb function,improving substance metabolism,preventing gene mutation,inhibiting tumor cell proliferation,inducing tumor cell differentiation or apoptosis,resisting tumor invasion and metastasis,inhibiting formation of tumor vessel and activity of telomerase,etc.It's possibly the result of synergistic effect by multi-pathway and multi-target.

研究表明，扶正培本药物具有增强和调节机体免疫功能、保护骨髓及提高机体造血机能、增加消化吸收功能，改善物质代谢、阻止基因突变、抑制肿瘤细胞增殖、诱导分化、促使肿瘤细胞凋亡、抗肿瘤侵袭与转移、抑制肿瘤血管形成及肿瘤细胞端粒酶活性等多种作用，其发挥的扶正作用可能是多途径、多靶点联合协同作用的结果。

Background and objective Cell adhesion and tumor metastasis can be regulated by p120^ctn.

背景与目的p120^ctn可以通过改变Rho GTP酶的状态进而调节细胞的黏附和肿瘤的转移。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
