| 1 | Structure of the Ca2+-dependent PP2A heterotrimer and insights into Cdc6 dephosphorylation显示文摘B″蛋白质磷酸酶 2A (PP2A ) 的 /PR72 家庭一个重要 PP2A 家庭涉及多样的细胞的过程,并且特别地由钙绑定调整了到规章的子单元。在这个家庭的 PR70 子单元与房间部门控制 6 交往(Cdc6 ) ,为 DNA 复制的控制重要的一个房间周期管理者。这里,我们在 2.1 和 2.4 Å 的一个决定报导孤立的 PR72 和 trimeric PR70 holoenzyme 的水晶结构;,分别地并且在 Cdc6 dephosphorylation 的 vitro 描述。holoenzyme 结构表明 PR70 钙绑定主题之一直接联系支架子单元,导致在所有 PP2A holoenzymes 之中的最紧缩的支架子单元符合构造。PR70 也在活跃地点附近区别地绑在催化子单元,它被要求让 PR70 向 Cdc6 提高磷酸酶活动。我们的研究为 B″ 的唯一的规定提供一个结构的基础;由钙离子的 /PR72 holoenzymes,并且在 PP2A holoenzymes 之中为底层特性的精确控制建议机制。 | Nathan Wlodarchak Feng Guo Kenneth A Satyshur Li Jiang Philip D Jeffrey Tingwan Sun Vitali Stanevich Marc C Mumby Yongna Xing | 2013 | Cell Research2013，23，7： | 3 |
| 2 | Variations in Wool Growth with Nutrient Supply in Northern China显示文摘Field studies on essessment of nutritional status of the grazing sheep were carried out in each of the three major grassland regions, the eastern Inner Mongolia and beyond grassland, the Inner Mongolia - Ningxia - Gansu grassland and the Xinjiang grassland, in northern China. The results obtained showed that the wool production of fine wool sheep in these regions varied between regions and seasons, with similar seasonal patterns in all regions and that reducing the seasonal variations in nutrient supply would enhance wool production substantially. Nutritional limitations to wool growth of the grazing sheep in these regions were suggested, those were: the shortage of protein supply in winter and early spring; the poor quality of much of the pasture and the hay used as supplements, the low energy intake during winter which probably necessitated the use of body stores to maintain body temperature. | D X Lu,Iner(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)Z C Feng,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)H R Wang,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)R Z Yang,(Xinjiang Institute of Animal Science.Xinjiang Academy of Animal Science.Yiu Hou Road.Urumqi.Xinjiang Uygur Autonomous Region PRC)C T Ma,(Chinese Academy of Agricultural Sciences.Lanzhou.Gansu.PRC)D B Purser,(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)J R Lindsay(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)D W Peter(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014) | 1997 | 畜牧与饲料科学1997，22，S1： | 3 |
| 3 | Terahertz Semiconductor Quantum Well Devices显示文摘For eventually providing terahertz science with compact and convenient devices,terahertz (1~10THz) quantum-well photodetectors and quantum-cascade lasers are investigated.The design and projected detector performance are presented together with experimental results for several test devices,all working at photon energies below and around optical phonons.Background limited infrared performance (BLIP) operations are observed for all samples (three in total),designed for different wavelengths.BLIP temperatures of 17,13,and 12K are achieved for peak detection frequencies of 9.7THz(31μm),5.4THz(56μm),and 3.2THz(93μm),respectively.A set of THz quantum-cascade lasers with identical device parameters except for doping concentration is studied.The δ-doping density for each period varies from 3.2×1010 to 4.8×1010cm-2.We observe that the lasing threshold current density increases monotonically with doping concentration.Moreover,the measurements for devices with different cavity lengths provide evidence that the free carrier absorption causes the waveguide loss also to increase monotonically.Interestingly the observed maximum lasing temperature is best at a doping density of 3.6×1010cm-2. | Liu H C Luo H Ban D Waichter M Song C Y Wasilewski Z R Buchanan M Aers G C SpringThorpe A J Cao J C Feng S L Williams B S Hu Q | 2006 | Journal of Semiconductors2006，27，4： | 2 |
