1Study of brain morphology change in Alzheimer’s disease and amnestic mild cognitive impairment compared with normal controls显示文摘Background With an aggravated social ageing level, the number of patients with Alzheimer's disease (AD) is gradually increasing, and mild cognitive impairment (MCI) is considered to be an early form of Alzheimer's disease. How to distinguish diseases in the early stage for the purposes of early diagnosis and treatment is an important topic. Aims The purpose of our study was to investigate the differences in brain cortical thickness and surface area among elderly patients with AD, elderly patients with amnestic MCI (aMCI) and normal controls (NC). Methods 20 AD patients, 21 aMCIs and 25 NC were recruited in the study. FreeSurfer software was used to calculate cortical thickness and surface area among groups. Results The patients with AD had less cortical thickness both in the left and right hemisphere in 17 of the 36 brain regions examined than the patients with aMCI or NC. The patients with AD also had smaller cerebral surface area both in the left and right hemisphere in 3 of the 36 brain regions examined than the patients with aMCI or NC. Compared with the NC, the patients with aMCI only had slight atrophy in the inferior parietal lobe of the left hemisphere, and no significant difference was found. Conclusion AD, as well as aMCI (to a lesser extent), is associated with reduced cortical thickness and surface area in a few brain regions associated with cognitive impairment. These results suggest that cortical thickness and surface area could be used for early detection of AD.Huanqing Yang Hua Xu Qingfeng Li Yan Jin Weixiong Jiang Jinghua Wang Yina Wu Wei Li Cece Yang Xia Li Shifu Xiao Feng Shi Tao Wang 2019General Psychiatry2019,32,2:3
2An Olefinic 1,2-α-Boryl Migration Enables 1,2-Bis(boronic esters)via Radical-Polar Crossover Reaction显示文摘A radical-induced 1,2-α-boryl migration through radical polar crossover reactions has been described.In this work,in situ formed vinyldiboron“ate”complexes from alkenyl Grignard reagent and diborylalkanes react with commercial radical precursors under light initiation.This three-component process enables diborylation of alkene.This protocol features high atom economy,a broad substrate scope as well as good functional group toleration with mild conditions.Feng Zhang Shangteng Liao Lu Zhou Kai Yang Chenglan Wang Yixian Lou Cece Wang Qiuling Song 2022Chinese Journal of Chemistry2022,40,5:0
3Atom Recombination of Difluorocarbene Enables 3-Fluorinated Oxindoles from 2-Aminoarylketones显示文摘Contrary to the traditional implementation as a difluoromethyl group and recently disclosed role of C1 synthons in synthetic organic chemistry,difluorocarbene(:CF_(2))is reported herein to proceed in unprecedented atom recombination as both a C1 synthon and F1 reagent simultaneously to render valuable 3-fluorinated oxindoles from 2-aminoarylketones.The reaction does not require catalyst and features a broad range of substrates with good functional group compatibility and ease of execution.This transformation could be employed to the quick-constructions of certain bioactive molecule derivatives.The mechanistic experiments and density functional theory(DFT)calculations indicate that this atom recombination reaction of:CF_(2) for the synthesis of 3-fluorinated oxindoles may involve a rearrangement process of epoxide intermediates.Guan Zhang Qianqian Shi Mengyuan Hou Kai Yang Shihui Wang Shuai Wang Wangyang Li Chaokun Li Jian Qiu Hetao Xu Lu Zhou Cece Wang Shi-Jun Li Yu Lan Qiuling Song 2022CCS Chemistry2022,4,5:0
4Microbial diversity assembled from series-diluted suspensions of disease-suppressive soil determines pathogen invasion resistance显示文摘Dear Editor,Soil microbial biodiversity loss caused by agricultural intensification, climate change, and the application of chemical fertilizer has become a serious problem that threatens humans (Wall et al., 2015). One phenomenon responsible for economic and food security issues is soil-borne diseases(Fisher et al., 2012), which were reported to be associated with microbial diversity loss (Shen et al., 2013;Fu et al.,2017).Yannan OU Zongzhuan SHEN Beibei WANG Menghui DONG Cece QIAO Rong LI Qirong SHEN 2021Pedosphere2021,31,1:0
5Rh-Catalyzed diastereoselective addition of arylboronic acids to α-keto N-tert-butanesulfinyl aldimines: synthesis of α-amino ketones显示文摘Herein we present a diastereoselective addition of arylboronic acids toα-keto N-tert-butanesulfinyl aldi-mines catalyzed by a Rh(I)catalyst.This reaction provides a practical method to obtain valuable chiralα-amino ketones with excellent diastereoselectivity,featuring operational simplicity,mild reaction con-ditions and a broad substrate scope.Cece Wang Lu Zhou Jian Qiu Kai Yang Qiuling Song 2022Organic Chemistry Frontiers2022,9,4:0
