(SNP),NO 清除剂牛血红蛋白(Hb)及 SNP 类似物亚铁氰化钠(SF)分别处理小麦幼苗,研究 NO 在镉 (Cd)胁迫下对小麦幼苗抗氧化系统的影响.结果显示,SNP 处理可以缓解镉胁迫对幼苗生长抑制,显著增加可溶性蛋白,叶绿素 和 GSH 含量,减少丙二醛(MDA)和过氧化氢(H2O2)的含量,并降低超氧阴离子(O2·-)产生速率,可溶性...

1.2 一氧化氮合酶(NOS)途径在哺乳动物体内,主要通过 NOS 形成 NO,NOS 以 L-精氨酸、O2 及 NADPH 为底物催化而成,FAD、FMN、血红素、四氢叶酸、Ca2+/CaM 和 Zn2+为 NOS 的辅基[18],其反应过程为:L-精氨酸 + NADPH + O2→NO+ L-胍氨酸 +NADP。根据细胞类型,动物中 NOS 可分为:神经型 NOS(nNOS)...

NO能与O2快速反应生产NO2,然后快速降解为硝酸根离子(NO3-)和亚硝酸根离子(NO2-)。NO广泛存在于生物体内(臧梦维等1996),是一种细胞间和细胞内信息传递的信使分子。近年来认为NO是一种在植物中普遍存在的关键信号分子(Durner et al.,1998;Wendehenne et al.,2004),NO的作用范围主要是产生NO的细胞和邻近的细胞...

Still not roaming to O2 network but EE, when on EE it seems to connect but unable to make/receive calls (even on 3G), I have to force it to 3 and unable to force to O2 or Vodafone to make/receive calls.Now back in Belgium it works ok on Base 4G, no no service, no need to...
