古近纪是陆地和海洋生态系统劫后复苏并逐渐接近其现代面貌的关键时期.在青藏高原及其周边区域,古近纪也是青藏高原-喜马拉雅造山带构造活动、亚洲气候重组、生物多样性演化的重要时期.限于研究条件、认识程度等的制约,青藏高原及其周边地区在地层划分方面还存在诸多争议.近年来,该区域开展了大量的沉积岩石学、磁性地层学、同位素年代学等工作,发现和报道了大量各种门类的化石,更系统地深化了生物地层学研究,为梳理青藏高原及其周边古近纪综合地层、生物群和古地理演化打下了坚实的基础.本文基于国际古近系划分和对比标准,以岩石地层和生物地层为基础,综合近年来同位素年代学、磁性地层学和地球化学等研究工作,在前人工作基础上梳理青藏高原及其周边不同构造单元的地层划分与对比框架.第二次青藏高原综合科学考察开展以来,古近纪植物群相关研究逐渐丰富.依据这些植物群最新的年代结果,本文讨论了灭绝类群和新出现类群的生物地层意义.对“桉属”、棕榈科等化石类群的新认识将古近纪青藏地区植物区系与冈瓦纳大陆的大洋洲、南美洲生物区系建立联系.雅鲁藏布江缝合带两侧植物群重要类群的演化历史也指示印度板块和欧亚大陆的碰撞时间在约65~54Ma.植物群的古高程重建结果表明,横断山区在早渐新世之前就已经形成现今的地貌格局;古近纪青藏地区主要缝合带附近的温暖湿润低地是动植物类群交流的主要通道;古近纪低矮的喜马拉雅山脉不能对南来的印度洋水汽形成有效的阻隔作用.

Role of FK506-binding protein in Ca^(2+) spark regulation

引用

Science Bulletin 2017年第19期62卷 1295-1303页

作者： Yan-ting zhao Yun-Bo guo Xue-Xin Fan Hua-Qian Yang Peng zhou zheng Chen Qi Yuan Haihong Ye Guang-ju ji Shi-Qiang Wang State Key laboratory of Membrane Biology College of Life SciencesPeking University National laboratory of Biomacromolecules Institute of BiophysicsChinese Academy of Sciences School of Basic Medical Sciences Beijing Institute for Brain Disorders Center of SchizophreniaCapital Medical University

the elementary Ca^2＋ release events, Ca2＋ sparks, has been found for a quarter of century. However, the molecular regulation of the spark generator, the ryanodine receptor （RyR） on the sarcoplasmic reticulum, remains obscure. Although each subunit of the RyR homotetramer has a site for FKS06-binding protein （FKBP）, the role of FKBPs in modifying RyR Ca^2＋ sparks has been debated for long. One of the reasons behind the controversy is that most previous studies detect spontaneous sparks, where the mixture with out-of-focus events and local wavelets prevents an accurate characterization of Ca^2＋ sparks. In the pre- sent study, we detected Ca^2＋ sparks triggered by single l-type Ca^2＋ channels （lCCs） under loose-seal patch clamp conditions in FKS06-treated or FKBPI2.6 knockout cardiomyocytes. We found that FKBP dissociation both by FKS06 and by rapamycin decreased the Ca^2＋ spark amplitude in ventricular cardiomyocytes. this change was neither due to decreased releasable Ca^2＋ in the sarcoplasmic reticulum, nor explained by changed RyR sensitivity. Actually FKS06 increased the lCC-RyR coupling probability and curtailed the latency for an lCC to trigger a RyR Ca^2＋ spark. FKBP12.6 knockout had similar effects as FKS06/rapamycin treatment, indicating that the decreased spark amplitude was attributable to the dissociation of FKBP12.6 rather than FKBP12. We also explained how decreased amplitude of spontaneous sparks after FKBP dissociation sometimes appears to be increased or unchanged due to inappropriate data processing. Our results provided firm evidence that without the inter-RyR coordination by functional FKBP12.6, the RyR recruitment during a Ca^2＋ spark would be compromised despite the sensitization of individual RyRs.

the Water Cherenkov Detector Array(WCDA) is a major component of the large High Altitude Air Shower Array Observatory(lHAASO), a new generation cosmic-ray experiment with unprecedented sensitivity, currently under construction. WCDA is aimed at the study of teV γ-rays. In order to evaluate the prospects of searching for teV γ-ray sources with WCDA, we present a projection of the one-year sensitivity of WCDA to teV γ-ray sources from teVCat using an all-sky approach. Out of 128 teVCat sources observable by WCDA up to a zenith angle of 45°, we estimate that 42 would be detectable in one year of observations at a median energy of 1 teV. Most of them are Galactic sources, and the extragalactic sources are Active Galactic Nuclei(AGN).
