简介:一个壶实验被执行在在栽培变种,超级米饭变化Ningjing1和传统的变化Zhendao11,它当前是商业地在南京使用了的二米饭之间的植物生产率和CH4排放学习差别,中国。CH4排放流动和土壤答案CH4内容的类似的季节的变化在测试栽培变种之间被发现。尽管在在栽培变种之间的植物生物资源生产没有重要差别,Ningjing1的谷物收益在35.0%是显著地更高的(P<0.05)与比Zhendao11,而从Ningjing1的全部的CH4排放是,35.2%降低(P<0.05)。在在栽培变种之间的CH4排放的数量的主要差别从tillering阶段发生在时期到出发阶段。可伸缩生物资源、可伸缩收益的CH4排出物是分别地为Ningjing1的3.8和5.2mg/g,显著地为Zhendao11比那些降低(7.4和12.8mg/g,分别地)。根据在植物生长特征和CH4排放之间的关系,一个更强壮的根系统主要作出贡献到Ningjing1的更低的CH4排放,作为与Zhendao11相比。我们的结果证明超级米饭不仅在谷物生产率而且在CH4排放缓解有优点。收割的超级米饭的进一步的扩大将在中国提高米饭收益和还原剂温室气体排放。

简介:摘要目的观察选择性深低温对猴脑结构和神经元微管蛋白MAP-2表达的的影响。方法4-10岁健康恒河猴8只,随机分为2组双侧颈总动脉阻断冷灌注组(简称深低温组,n=5),双侧颈总动脉阻断常温灌注组(简称常温组,n=3)。常温下临时阻断双侧颈部血管10分钟后,通过一侧颈内动脉冷灌注,同侧颈内静脉回流,阻断其它颈部血管,建立选择性脑局部体外循环通路,降低脑温至18℃,60min恢复脑血流,实验动物自然复苏。脑组织多取材石蜡包埋切片行光镜检查及MAP-2免疫组化检测。结果深低温组脑组织形态未见明显异常。常温组示神经细胞溶解坏死。常温组与深低温比较,MAP-2表达下降(P<0.01);结论选择性深低温能够降神经元Map-2的崩解从而减少脑缺血对神经元的破坏作用。
