1An epigenomic approach to therapy for tamoxifen-resistant breast cancer显示文摘Tamoxifen 是为雌激素受体 alpha 的前线治疗(ERα) 在绝经前的女人的积极的胸肿瘤。然而,到 tamoxifen 的抵抗发生在许多病人。嗯仍然与获得的 tamoxifen 抵抗在乳癌房间的生长起一个关键作用,建议那 ERα为治疗仍然是一个有效目标 tamoxifen 抵抗(Tam-R ) 乳癌。以识别 ERα 的新奇管理者;发信号,通过对 histone 甲基修饰词的一幅小规模的 siRNA 屏幕,我们发现了 WHSC1, histone H3K36 methyltransferase, ERα 的一个积极管理者;在乳癌房间发信号。我们证明 WHSC1 被招募到 ERα由 BET 蛋白质 BRD3/4 的基因,并且便于 ERα基因表示。小分子的赌注蛋白质禁止者 JQ1 potently 压制了经典 ERα发信号的小径和在文化的 Tam-R 乳癌房间的生长。用一个 Tam-R 乳癌异种皮移植老鼠模型,我们与 JQ1 和 ER degrader fulvestrant 由 JQ1 和联合治疗的强壮的长持续的效果在 vivo 反胸癌症活动示威了。一起拿,我们提供 epigenomic 蛋白质 BRD3/4 和 WHSC1 是雌激素受体发信号的必要管理者并且是为 Tam-R 乳癌的治疗的新奇治疗学的目标的证据。Qin Feng Zheng Zhang Martin J Shea Chad J Creighton Cristian Coarfa Susan G Hilsenbeck Rainer Lanz Bin He Lei Wang Xiaoyong Fu Agostina Nardone Yongcheng Song James Bradner Nicholas Mitsiades Constantine S Mitsiades C Kent Osborne Rachel Schiff Bert W O'Malley 2014Cell Research2014,24,7:10

3全颗粒饲料对奶牛生产性能的影响显示文摘饲料中的中性洗涤纤维(NDF)含量和饲料颗粒直径是影响瘤胃功能的重要因素。试验评估了以颗粒饲料为主的奶牛瘤胃健康情况、NDF消化率和生产性能。选取8头荷斯坦母牛(336±30 d,体重346±35 kg),随机分配到交叉重复试验组中,奶牛安置于牛栏,自由采食。试验期为3周,前两周是适应期,最后一周为数据收集期。各组饲粮原料相同,但物理形式不同,分为全混合日粮(TMR)和颗粒料(直径=8 mm)。两组间物理有效NDF(pe NDF)不同,TMR组为39.8%,颗粒料组为11.8%。在试验过程中,干物质采食量(DMI)、饮水量、瘤胃反刍时间、瘤胃温度和pH情况均记录。3周后收集粪样,确定潜在的可消化NDF总消化率(pdNDF)。每阶段结束后计算平均日增重和饲料转化率。颗粒料组的DMI、DMI/体重和饮水量更高。而两组间平均日增重和饲料转化率无显著差异。颗粒料组的瘤胃反刍时间为241 min·d-1低于TMR组的507 min·d-1。饲料的不同物理外形对瘤胃温度、瘤胃pH无显著影响。TMR组的pdNDF总消化率为90.25%高于颗粒料组的86.82%。试验结果表明,动物易接受完整的颗粒饲料,DMI较高,且反刍时间减少,但瘤胃pH无显著变化。TMR组的pdNDF消化率显著增加。尽管两组奶牛在DMI和纤维消化方面表现不同,但总体表现相似,两组饲料的保存时间与其物理形式有关。在短期内,提供能满足NDF需求的完全颗粒饲料可改善瘤胃健康状况和动物生产性能,而较长时间的数据则需要进一步试验。Wang J Yang M Cao M Lin Y Che L Q Duraipandiyan V Al-Dhabi N A Fang Z F Xu S Y Feng B Liu G Wu D Bonfante E Palmonari A Mammi L Canestrari G Fustini M Formigoni A 2016饲料博览2016,0,12:2
4Terahertz 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 2006Journal of Semiconductors2006,27,4:2
