    基于核磁共振(NMR)的代谢组学是一门新兴的“组学”学科,它将1H-NMR波谱检测技术和模式识别分析技术相结合,被广泛应用于疾病的早期诊断、病理机制、药物的药效评估、微生物环境胁迫适应性等研究。本论文应用基于NMR技术的代谢组学方法,研究艾塞那肽Exendin-4(胰高血糖素样肽-1(GPL-1)类药物)对糖尿病肾病(DKD)大鼠的肾功能保护机制以及深海沉积微杆菌YLB-01耐受高压低温的分子机制。 糖尿病肾病(DKD)发病机制尚不完全明确。最近的研究表明GLP-1类药物(如Exendin-4)可能通过改善代谢来抑制DKD的发生发展,但其作用机制并不明确。为了揭示Exendin-4保护DKD...Nuclear magnetic resonance (NMR)-based metabonomics approach is a newly emerging “omic” discipline with the integration of NMR technique and pattern recognition analysis.

    厦门大学人类学研究所、厦门大学生命科学学院细胞应激生物学国家重点实验室王传超教授课题组与哈佛医学院David Reich教授团队合作,联合全球43个单位的85位共同作者组成的国际合作团队通过古DNA精细解析东亚人群形成历史。研究人员利用古DNA数据检验了东亚地区农业和语言共扩散理论,综合考古学、语言学等证据,该研究系统性地重构了东亚人群的形成、迁徙和混合历史。这是目前国内开展的东亚地区最大规模的考古基因组学研究,此次所报道的东亚地区古人基因组样本量是以往国内研究机构所发表的样本量总和的两倍,改变了东亚地区尤其是中国境内考古基因组学研究长期滞后的局面。 该研究是由王传超教授团队与哈佛医学院(David Reich教授)、德国马普人类历史科学研究所(Johannes Krause教授)、复旦大学现代人类学教育部重点实验室(李辉教授和金力院士)、维也纳大学进化人类学系(Ron Pinhasi副教授)、南洋理工大学人文学院(Hui-Yuan Yeh助理教授)、俄罗斯远东联邦大学科学博物馆(Alexander N Popov研究员)、西安交通大学(张虎勤教授)、蒙古国国家博物馆研究中心、乌兰巴托国立大学考古系、华盛顿大学人类学系、台湾成功大学考古所、加州大学人类学系等全球43个单位的85位共同作者组成的国际合作团队联合完成的。厦门大学人类学研究所、厦门大学生命科学学院细胞应激生物学国家重点实验室为论文第一完成单位。厦门大学人类学研究所韦兰海副教授、胡荣助理教授、郭健新博士后、何光林博士后和杨晓敏硕士参与了研究工作。The deep population history of East Asia remains poorly understood due to a lack of ancient DNA data and sparse sampling of present-day people1,2. We report genome-wide data from 166 East Asians dating to 6000 BCE-1000 CE and 46 present-day groups. Hunter-gatherers from Japan, the Amur River Basin, and people of Neolithic and Iron Age Taiwan and the Tibetan plateau are linked by a deeply-splitting lineage likely reflecting a Late Pleistocene coastal migration. We follow Holocene expansions from four regions. First, hunter-gatherers of Mongolia and the Amur River Basin have ancestry shared by Mongolic and Tungusic language speakers but do not carry West Liao River farmer ancestry contradicting theories that their expansion spread these proto-languages. Second, Yellow River Basin farmers at ~3000 BCE likely spread Sino-Tibetan languages as their ancestry dispersed both to Tibet where it forms up ~84% to some groups and to the Central Plain where it contributed ~59-84% to Han Chinese. Third, people from Taiwan ~1300 BCE to 800 CE derived ~75% ancestry from a lineage also common in modern Austronesian, Tai-Kadai and Austroasiatic speakers likely deriving from Yangtze River Valley farmers; ancient Taiwan people also derived ~25% ancestry from a northern lineage related to but different from Yellow River farmers implying an additional north-to-south expansion. Fourth, Yamnaya Steppe pastoralist ancestry arrived in western Mongolia after ~3000 BCE but was displaced by previously established lineages even while it persisted in western China as expected if it spread the ancestor of Tocharian Indo-European languages. Two later gene flows affected western Mongolia: after ~2000 BCE migrants with Yamnaya and European farmer ancestry, and episodic impacts of later groups with ancestry from Turan.We thank David Anthony, Ofer Bar-Yosef, Katherine Brunson, Rowan Flad, Pavel Flegontov,Qiaomei Fu, Wolfgang Haak, Iosif Lazaridis, Mark Lipson, Iain Mathieson, Richard Meadow,Inigo Olalde, Nick Patterson, Pontus Skoglund, Dan Xu, and the four reviewers for valuable comments.

    无意识种族信息知觉加工

    目的:在种族信息加工领域,前人通过持续闪现抑制(CFS)范式在社会评价层面发现了无意识的本族效应(Yuan et al., 2017),即被试对无意识呈现的异族面孔存在偏见。但是,无意识呈现的种族面孔能否在知觉水平得到加工还尚无定论,且研究甚少,本研究采用bCFS(突破CFS)考察无意识呈现的本族面孔在知觉水平是否具有优势。 方法:本研究包含两个实验。实验1的目标刺激为标准化的中国人与白人黑白面孔,通过红蓝眼镜呈现在中国被试的非优势眼;高对比度、彩色、快速闪现的蒙德里安(Mondrian)色块作为掩蔽刺激呈现在被试的优势眼。面孔刺激的对比度在1秒内从0增加到100%并保持不变,直至被试按键;因此,在开始阶段,面孔是被抑制的,实现了无意识的效果。面孔随机出现在中央注视点两侧的两条弧形轨迹上,被试的任务是判断面孔出现在注视点左侧或右侧。此外,实验1还包含一个对照实验,实验中蒙德里安色块和面孔刺激同时呈现在被试的双眼。实验2为了排除种族面孔所存在的熟悉性差异,采用两种几何图形,与种族概念进行联结学习。除了刺激为联结后的图形,实验2与实验1基本相同。 结果:实验1发现与异族面孔相比,本族面孔能更快突破抑制进入意识;而对照实验未发现差异,排除了面孔低水平物理属性的影响。实验2发现被试在本族的联结学习中表现更好,反应时更快,正确率更高。同时,代表本族的图形在突破抑制上也存在优势,而对照实验则未发现差异。实验2重复了实验1的结果,排除了面孔熟悉性的影响。 结论:本研究通过两个实验,发现种族信息可以在无意识下得到加工,无意识呈现的本族面孔与代表本族的图形在知觉水平上存在优势。</p
