高迁移率组蛋白N2(High Mobility Group Chromosal protein N2,HMGN2)是脊椎动物和非脊椎动物的细胞核中普遍存在的非组蛋白,目前对其功能还不完全清楚。在本实验室从人LAK细胞和人宫颈黏液中分离纯化寻找抗菌肽过程中,发现HMGN2具有较强的抗革兰氏阴性菌的作用,为进一步深入研究HMGN2的生物学新功能,本文重点研究其体外抗乙型肝炎病毒(Hepatitis B
In this paper, the problem of stability analysis of discrete-time delay systems with two additive time-varying delays is considered. A new stability result is d
