Interface Issues of Inorganic Solid‐State Electrolytes in Secondary Magnesium Batteries
Rare Metals, EarlyView.ABSTRACT Solid‐state magnesium batteries (SSMBs) have gained significant attention as promising candidates for next‐generation safe energy storage systems because of the abundance of magnesium (Mg) in the earth's crust, superior energy density, and inherent nonflammability.

细胞毒性T 淋巴细胞相关抗原4 基因型与中国南方人群Graves ’ 病的关系
Zhongshan Daxue xuebao. Yixue kexue ban, 2005 【目的】探讨细胞毒性T淋巴细胞相关抗原-4(cytotoxic T lymphocyte associated antigen 4)基因第一外显子A／G(49)多态性与中国南方汉族人群Graves′病的关系。【方法】用PCR-RFLP确定CTLA-4基因第1外显子49位点基因型，分析广东地区汉族人Graves′病患者(GD组)120例及123名正常人(对照组)CTLA-4基因多态性。并把GD患者按性别、家族史、TRAb、突眼等分别分两亚组后分析CTLA-4基因第1外显子A49G位点基因型及等位基因的频率。

The role of jumping translocation breakpoint gene promoting instability of genome and the biological function of its protein and potential clinical value [PDF]
, 2014 染色体不稳定性是大多数肿瘤细胞特别是实体瘤细胞和体外转化细胞的基本特征。其表现形式包括整条染色体的获得或缺失，杂合缺失，染色体易位重排，基因扩增等。目前认为染色体不稳定是肿瘤形成的始发因素，出现在肿瘤进展的早期阶段。体内外各种损伤刺激导致的基因组DNA链的断裂是染色体不稳定的根本原因。我们的研究发现，跳跃易位断裂点基因（JTB）在胃癌、肝癌中存在广泛的基因扩增和基因易位行为，而基因的扩增和易位是DNA双链断裂后异常修复的最终结果。JTB基因的断裂易位将导致其编码跨膜结构域的基因序列丢失 ...

Survey of viral diversity in the sediments of South China Sea [PDF]
, 2016 病毒是海洋生态系统中丰度最大，多样性最为丰富的微生物颗粒。海洋沉积物中的病毒丰度相比较海水中，要高1~2个数量级，并且其形态和基因型也更加多样。目前，人们对海洋沉积物中的病毒相关研究还比较少。为了增强对海洋沉积物中病毒的了解，本论文利用荧光显微镜法获得了珠江口沉积物以及南海北部和西部沉积物中病毒的丰度数据，并且通过病毒标记基因（g23&psbA）PCR扩增、克隆文库测序等分子技术获得了沉积物中T4类噬菌体和噬藻体类群的多样性信息。主要的研究结果： （1）荧光显微镜检测结果显示珠江口沉积物中病毒（4.49×
