GPηp具有特征厚度为7个原子层和结构稳定的双原子板。迄今为止,对于GP区转化为η′的转化机制还没有达成一致意见,不清楚η′是否是从GP I还是从GP II形成的。最近的原位TEM研究证明,GP I/Al界面可以作为GP II的核化点。 η′具有六角...
(导读 阿金)转录的增强子图谱可揭示阐释每个细胞类型的核互作,将特定细胞类型与疾病联系起来。本研究使用 5’单细胞 RNA 测序方法识别出人类 CD4+T 细胞内增强子 RNA 和其他类编码与非编码 RNA 的转录起始位点,展示了细胞异质性与分化轨迹。结果得到了双向转录增...

Ionic liquids are a class of emerging material for liquid membrane. Room-temperature ionic liquids are molten electrolytes that exhibit interesting solvent properties including nonvolatility and nonflammability, high viscosity, high thermal stability, and high solubility of a broad range of organic and ...
ParserNG comes with a FunctionManager class that allows users persist store functions for the duration of the session(JVM run). You may create and store a function directly by doing: FunctionManager.add("f(x,y) = x-x/y"); And then retrieve and use the function like this: ...
Educational videos are increasingly used to let students prepare lesson material at home prior to in-class activities in flipped classrooms. The main chall
单亚基效应物的Class II家族熟知的蛋白包括大家常用的Cas9, Cas12, Cas13等。Class I家族包括Cascade-Cas3, Csm, Cmr复合物等等。但是这些系统不管是哪类,都是sgRNA靶向和激活的核酸酶,对靶向的DNA或RNA进行切割。目前大家所使用的CRISPR-Cas技术都是围绕sgRNA靶向和RNA guided核酸酶展开的。
