Hemagglutinins inhibition ( hi ) testes showed that there were obvious variations among the isolates from different geographical areas. this result explained why the protection rates of current vaccine were different around the country. dna sequence analysis of h9 hemagglutinin genes showed that these viruses were closely related and possibly came from one source
且在同一地域內,不同的異變體之間的差異較小,隨著時間的推移,其變異並不明顯;但在不同的區域內分離的毒株之間變異較為突出,這表明中國大陸h9n2亞型禽流感病毒不同分離株抗原性是與地域的改變而發生較為明顯的變異。Answer : as patented product, spring tube adopts macromolecule compound material and the obvious characteristic is that it can keep good spring stability among different temperatures and guarantees innocuity and insipidity and anti aging, which can guarantee innocuity but benefit for body
答:作為專利發明的這種彈性管,是由高分子復合材料製成,真突出的特點是在不同溫度變化下保持彈性穩定以及確保無毒無味和抗老化,可以保證對人體有益無害。The aglycone, steviol, exhibited greater acute toxicity than stevioside in hamsters but not in rats. steviol was clearly genotoxic after metabolic activation, inducing forward mutations in bacteria and gene mutations and chromosomal aberrations in lung fibroblasts of chinese hamsters
甜菊醇經過代謝活化后,基因毒性明顯,可引致細菌產生正向突變,以及使中國倉鼠的肺纖維原細胞產生基因突變和染色體變異。It has been reported that the eiav s2 is not essential and does not appear to affect virus infection and replication in vitro. thus, we introduced a his - tag into the s2 gene of an eiav infectious molecular clone recombinant plasmid ( pok8266 ) by using soe pcr method and obtained a new recombinant plasmid with his - tag, designated as eiav - pok8. 2 - his
本研究應用已構建好的eiav驢白細胞弱毒疫苗株的感染性分子克隆載體( pok8266 )為模板,通過soepcr方法在感染性分子克隆載體的s2基因獨特區內引入突變點,形成含有酶切位點( nspv )的突變體( p1p4 ) 。With the prolong of contact time, the increment scope of ttms and halogen acetic acid will decrease. d ) comparing to chlorination, chloroamine disinfection is a better way in reducing the mutations of the objects in drinking water
D )氯胺消毒方式在減小飲用水的致突變性即降低飲用水的毒副方面明顯優于氯消毒,對總aoc的生成具有較好的抑制作用,水體生物穩定性優于氯消毒方式。Accumulating evidence indicates that nmda receptors are involved in many complex physiological and neuropathological mechanisms, such as neuronal developmental plasticity, long - term potentiation ( ltp ), learning and memory, excitotoxicity and neurodegenerative diseases etc. three gene families that encode nmda receptor subunits have been identified : nr1, nr2a - d, and nr3 subunit
已知nmda受體與許多復雜的生理和病理機制有關,如突觸的可塑性、長時程增強作用( ltp ) 、學習和記憶、興奮性神經毒性、神經退行性變性疾病等。已克隆到3個編碼nmda受體亞單位蛋白的基因家族,即nr1 、 nr2和nr3 。The results suggested that eaggec hpi - positive strains expressed the ybt system, but the presence of hpi core part does n ' t mean ybt expression. 2. research on the function of ybtp, ybtq and ybtx genes in eaggec 17 - 2 ybtp, ybtq and ybtx genes from yen wa were cloned respectively and mutated, then inserted by a selectable substitution with chloramphenicokcaf ) gene in vitro
