Understanding divergent domestication traits from the whole-genome sequencing of swamp- and river-buffalo populations

Domesticated buffaloes have been integral to rice-paddy agro-ecosystems for millennia, yet relatively little is known about the buffalo genomics. Here, we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals (132 swamp buffaloes and 98 river buffaloes) sampled from across Asia and Europe. Beyond the many actionable insights that our study revealed about the domestication, basic physiology and breeding of buffalo, we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior, digestion metabolism, strengths and milk production.     

A stage-specific cell-manipulation platform for inducing endothelialization on demand

Endothelialization is of great significance for vascular remodeling, as well as for the success of implanted vascular grafts/stents in cardiovascular disease treatment. However, desirable endothelialization on synthetic biomaterials remains greatly challenging owing to extreme difficulty in offering dynamic guidance on endothelial cell (EC) functions resembling the native extracellular matrix-mediated effects. Here, we demonstrate a bilayer platform with near-infrared-triggered transformable topographies, which can alter the geometries and functions of human ECs by tunable topographical cues in a remote-controlled manner, yet cause no damage to the cell viability. The migration and the adhesion/spreading of human ECs are respectively promoted by the temporary anisotropic and permanent isotropic topographies of the platform in turn, which appropriately meet the requirements of stage-specific EC manipulation for endothelialization. In addition to the potential of promoting the development of a new generation of vascular grafts/stents enabling rapid endothelialization, this stage-specific cell-manipulation platform also holds promise in various biomedical fields, since the needs for stepwise control over different cell functions are common in wound healing and various tissue-regeneration processes.     

网络诗歌与传统诗歌审美错位研究

作为诗歌新形式,网络诗歌的内在诗性也发生了一定变化,其审美取向与传统诗歌审美偏好出现错位与偏离.网络诗歌审美表现出的拒绝抒情传统、削平诗意表达深度、异化诗歌传统功能等新表征导致网络诗歌与传统诗歌审美之间出现抒情错位、表达错位和功能错位等现象.促使错位弥合的构想之一是大力倡导网络现代禅诗的创作与研究,这不仅有助于规范网络...

口述档案研究的可视化分析

本文通过对国内外口述档案研究的对比分析,可以了解国内外相关研究的差距之处,并且可以根据研究热点的变化,在一定程度上推测出国内外今后的研究方向和趋势。以中国知网(CNKI)和Web of Science为数据来源,基于Citespace软件,从年代分布、作者、发文机构、关键词等角度对国内外口述档案的研究进行分析。通过分析发现,在总体发文量上,国内关于口述档案的研究要低于国外,作者之间和机构之间的合作程度也是同样趋势。此外,国内外在口述档案领域的热点主要集中于口述档案与社会记忆相结合。因此,围绕"记忆、社会记忆"开展的口述档案研究可能是国内外共同的发展趋势。
