1Problems in wavelet analysis of hydrologic series and some suggestions on improvement显示文摘使用小浪理论和方法调查象降水和流量那样的水疗院逻辑过程是一个热领域。然而,切断,在研究的方面通常被忽略:小浪功能和为时期, find 结果上的一个水疗院逻辑时间系列的长度的效果,和在为小浪分析的异例和原来的时间系列之间的选择的察觉的噪音的骚乱的可被考虑的状况的效果。在这篇论文,这些问题充分被讨论。来自 Lanzhou 降水车站的降水数据为案例研究被拿。结果显示在水疗院逻辑系列的小浪分析,降噪方法应该被用来消除噪音的影响。MexHat 小浪函数满足可被考虑的条件,它保证水疗院逻辑进程的周期的性质能被为分解使用 MexHat 小浪很好代表。在分析被给以前,应该被丢弃的水疗院逻辑系列的影响范围。异例系列应该被用来加亮水疗院逻辑系列的实际波动,这也被建议。WANG Hongrui YE Letian LIU Changming YANG Chi LIU Peng 2007Progress in Natural Science:Materials International2007,17,1:13
2Multi-step formation, evolution, and functionalization of new cytoplasmic male sterility genes in the plant mitochondrial genomes显示文摘新基因起源是授与 phenotypic 变化和生物差异的 genomic 革新的主要来源。在植物的新 mitochondrial 基因的产生可以引起细胞质的男绝育(厘米) ,它能支持 outcrossing 和增加健康。然而, mitochondrial 基因怎么在结构和功能发源并且演变,仍然保持不清楚。米饭厘米的野未成功的类型被 mitochondrial 基因 WA352c (以前命名的 WA352 ) 授与并且广泛地在混合米饭繁殖被利用了。这里,我们重建由 11 mitochondrial genomic recombinant 的鉴定和分析的 WA352c 的进化轨道在野、栽培的米饭与 WA352c 有关组织。我们推断这些结构在野米饭 Oryza rufipogon,结合的 substoichiometric 变和顺序变化的 mitochondrial 染色体在保存 mitochondrial 序列之中通过多重重新整理产生了。我们鉴别二表示了,但是在这些结构之中的 nonfunctional protogenes,和他们能发展进功能的厘米基因经由的表演定序能减轻蛋白质的自我禁止的潜力的变化。这些顺序变化将资助蛋白质与编码原子核的 mitochondrial 蛋白质 COX11 交往的能力,在花药 tapetum 和男绝育导致早熟的规划房间死亡。而且,我们证明把 COX11 相互作用领域编码为这些 WA352c 相关的基因的序列经历了在进化期间净化选择。我们经由在结构,顺序,拷贝数字,和功能包含渐渐的变化的 multi-recombination/protogene formation/functionalization 机制为新厘米基因的形成和进化建议一个模型。Huiwu Tang Xingmei Zheng Chuliang Li Xianrong Xie Yuanling Chen Letian Chen Xiucai Zhao Huiqi Zheng Jiajian Zhou Shan Ye Jingxin Guo Yao-Guang Liu 2017Cell Research2017,27,1:11
3Lithospheric Electrical Structure across the Eastern Segment of the Altyn Tagh Fault on the Northern Margin of the Tibetan Plateau显示文摘Project INDEPTH(Inter National DEep Profiling of Tibet and the Himalaya) is an interdisciplinary program designed to develop a better understanding of deep structures and mechanics of the Tibetan Plateau. As a component of magnetotelluric(MT) work in the 4th phase of the project, MT data were collected along a profile that crosses the eastern segment of the Altyn Tagh fault on the northern margin of the plateau. Time series data processing used robust algorithms to give high quality responses. Dimensionality analysis showed that 2D approach is only valid for the northern section of the profile. Consequently, 2D inversions were only conducted for the northern section, and 3D inversions were conducted on MT data from the whole profile. From the 2D inversion model, the eastern segment of the Altyn Tagh fault only appears as a crustal structure, which suggests accommodation of strike slip motion along the Altyn Tagh fault by thrusting within the Qilian block. A large-scale off-profile conductor within the mid-lower crust of the Qilian block was revealed from the 3D inversion model, which is probably correlated with the North Qaidam thrust belt. Furthermore, the unconnected conductors from the 3D inversion model indicate that deformations in the study area are generally localized.ZHANG Letian YE Gaofeng JIN Sheng WEI Wenbo Martyn UNSWORTH Alan G.JONES JING Jianen DONG Hao XIE Chengliang Florian LE PAPE Jan VOZAR 2015Acta Geologica Sinica(English Edition)2015,89,1:1
4Medicinal chemistry strategies towards the development of non-covalent SARS-CoV-2 Mpro inhibitors显示文摘The main protease(M^(pro))of SARS-CoV-2 is an attractive target in anti-COVID-19 therapy for its high conservation and major role in the virus life cycle.The covalent M^(pro)inhibitor nirmatrelvir(in combination with ritonavir,a pharmacokinetic enhancer)and the non-covalent inhibitor ensitrelvir have shown efficacy in clinical trials and have been approved for therapeutic use.Effective antiviral drugs are needed to fight the pandemic,while non-covalent M^(pro)inhibitors could be promising alternatives due to their high selectivity and favorable druggability.Numerous non-covalent M^(pro)inhibitors with desirable properties have been developed based on available crystal structures of M^(pro).In this article,we describe medicinal chemistry strategies applied for the discovery and optimization of non-covalent M^(pro)inhibitors,followed by a general overview and critical analysis of the available information.Prospective viewpoints and insights into current strategies for the development of non-covalent M^(pro)inhibitors are also discussed.Letian Song Shenghua Gao Bing Ye Mianling Yang Yusen Cheng Dongwei Kang Fan Yi Jin-Peng Sun Luis Menéndez-Arias Johan Neyts Xinyong Liu Peng Zhan 2024Acta Pharmaceutica Sinica B2024,14,1:0
5Discovery of novel sulfonamide substituted indolylarylsulfones as potent HIV-1 inhibitors with better safety profiles显示文摘Indolylarylsulfones(IASs) are classical HIV-1 non-nucleoside reverse transcriptase inhibitors(NNRTIs) with a unique scaffold and possess potent antiviral activity.To address the high cytotoxicity and improve safety profiles of IASs,we introduced various sulfonamide groups linked by alkyl diamine chain to explore the entrance channel of non-nucleoside inhibitors binding pocket.48 compounds were designed and synthesized to evaluate their anti-HIV-1 activities and reverse transcriptase inhibition activities.Especially,compound R_(10)L_(4) was endowed with significant inhibitory activity towards wild-type HIV-1(EC_(50(WT))=0.007μmol/L,SI=30,930) as well as a panel of single-mutant strains exemplified by L100I(EC_(50)=0.017μmol/L,SI=13,055),E138K(EC_(50)=0.017μmol/L,SI=13,123) and Y181C(EC_(50)=0.045μmol/L,SI=4753) which were superior to Nevirapine and Etravirine.Notably,R_(10)L_(4) was characterized with significantly reduced cytotoxicity(CC_(50)=216.51μmol/L) and showed no remarkable in vivo toxic effects(acute and subacute toxicity).Moreover,the computer-based docking study was also employed to characterize the binding mode between R_(10)L_(4) and HIV-1 RT.Additionally,R_(10)L_(4) presented an acceptable pharmacokinetic profile.Collectively,these results deliver precious insights for next optimization and indicate that the sulfonamide IAS derivatives are promising NNRTIs for further development.Shenghua Gao Letian Song Yusen Cheng Fabao Zhao Dongwei Kang Shu Song Mianling Yang Bing Ye Wei Zhao Yajie Tang Erik De Clercq Christophe Pannecouque Peng Zhan Xinyong Liu 2023Acta Pharmaceutica Sinica B2023,13,6:0
