2024年5月29日,中国农业科学院深圳农业基因组研究所(岭南现代农业科学与技术广东省实验室深圳分中心)徐炜团队开发了一项高通量、低成本R-loop定量图谱绘制技术“mDRIP-seq”,并应用该技术绘制了酿酒酵母突变株R-loop定量图谱。该研究成果以“mDRIP-seq is a high-throughput method for quantitative profiling of R-lo...
次生代谢产物异黄酮是一类主要在豆科植物中合成的多酚类物质。异黄酮不仅利于豆科植物应答生物和非生物胁迫、诱导根瘤形成等,而且对人体具有重要的保健和药用价值,比如预防和治疗癌症、心脑血管疾病和骨质疏松等。大豆是工业化生产异黄酮的重要来源,主要含有12种异黄酮物质及其衍生物。根据其化学结构的差异,可将其分为游离型苷元(aglycone)和结合型糖苷(glycoside)两大类,其中结合型糖苷占异黄酮总量...
For each central charge c\in (0,1], we construct a conformally invariant field which is a measurable function of the local time field \mathcal{L} of the Brownian loop soup with intensity c and i.i.d. ...
基因表达调控是决定细胞命运的重要因素,通过改变基因的表达模式即可实现对细胞命运的精准调控。比如运用Yamanaka四个转录因子(Oct4, Sox2, Klf4, c-Myc)在体外就可将体细胞成功重编程为诱导多能干细胞。2020年6月10日,中国科学院广州生物医药与健康研究院/广州再生医学与健康广东省实验室姚红杰课题组联合清华大学生命科学学院孙前文课题组在国际学术期刊Science Advanc...
R-loop是一种由RNA:DNA杂合链和单链DNA组成的特殊核酸结构,在原核和真核生物的基因组中分布广泛且普遍存在。R-loop在很多关键的生物学过程中发挥重要功能,包括染色质修饰、转录调控、DNA损伤修复以及基因组稳定性等,但其如何被精确调控的机制尚不清楚。m6A修饰作为信使RNA上丰度最高的修饰类型,广泛参与哺乳动物的发育、免疫、干细胞更新、脂肪分化、以及肿瘤生成和转移等生命过程。然而,目前...
环路空间,超对称与指标理论研讨会将于2017.7.17-7.21在南开大学陈省身数学研究所举行。
Chern Institute of Mathematics (CIM) was founded through the initiative of the late Professor Shiing-Shen Chern, who was also the first director of the Institute until 1992. The institute is located i...
A thymidine phosphoramidite labelled at C6 with 13C has been synthesized, and incorporated into a synthetic oligonucleotide, d(CGCGT*T*GT*T*CGCG), which adopts a hairpin conformation. NMR relaxation m...
The maternally inherited mitochondrial DNA (mtDNA) D–loop region is widely used for exploring genetic relationships and for investigating the origin of various animal species. Currently, domestic duck...
In closed-loop convex analysis and design, the linear controller design problem is reformulated as a convex optimization problem, which may be more easily solved than the problems resulting from conve...
We show that control system design via classical loop shaping and singular value loop shaping can be formulated as a closed-loop convex problem. Consequently, loop shaping problems can be solved by ef...
The Microbial Loop     Microbial Loop  ocean       2015/7/22
Answering Charles Darwin's prescient question has taken us nearly two centuries. Only in recent decades have methods and concepts been developed to explore the significance of microbes in the ocean's ...
The Phase-Locked Loop(PLL) is a key component of modern electronic communication and control systems. PLL is designed to extract signals from transmission channels. It plays an important role in syste...
Genetic variation in three Croatian coldblood horse populations was analysed using a sequence analysis of the proximal part (nt 15 498?5 821) of the D-loop region of mtDNA. Twenty unrelated horses wer...
This paper provides some background to the theory of operads, used in the first author's papers on 2d topological field theory (hep-th/921204, CMP 159 (1994), 265-285; hep-th/9305013). It is intended ...
