Regulating the level of amino acid neurotransmitters in the hippocampus might be one of the antidepressive mechanisms of low frequency rTMS. 对海马内氨基酸递质水平的调节作用是低频rTMS的抗抑郁机制之一。
RESULTS: A random cycle peptide library with 1.28 × 10 7 different recombinant clones was obtained. No significant difference was found between amino acid distribution in the cycle peptide library and the expected frequency. 结果:构建了酵母双杂交随机环肽库,库容为1.28×107,氨基酸分布与理论频数无显著差异,并扩增获得大量高纯度的环肽库质粒。
Objective To compare partial nucleotide and amino acid sequences between epidemic and sporadic hepatitis E viruses ( HEV) in China and their relation to the frequency of hepatitis E ( HE). 比较我国流行性和散发性戊型肝炎病毒(HEV)的部分核苷酸和氨基酸序列及其与戊型肝炎流行的关系。
