1Anti-parkinsonian effects of octacosanol in 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine-treated mice显示文摘Our previous research showed that octacosanol exerted its protective effects in 6-hydroxydopamine-induced Parkinsonian rats. The goal of this study was to investigate whether octacosanol would attenuate neurotoxicity in 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine (MPTP)-treated C57BL/6N mice and its potential mechanism. Behavioral tests, tyrosine hydroxylase immunohistochemistry and western blot were used to investigate the effects of octacosanol in a mouse model of Parkinson's disease. Oral administration of octacosanol (100 mg/kg) significantly improved behavioral impairments in mice treated by MPTP and markedly ameliorated morphological appearances of tyrosine hydroxylase-positive neuronal cells in the substantia nigra. Furthermore, octacosanol blocked MPTP-induced phosphorylation of p38MAPK and JNK, but not ERK1/2. These findings implicated that the protective effects afforded by octacosanol might be mediated by blocking the phosphorylation of p38MAPK and JNK on the signal transduction in vivo. Considering its excellent tolerability, octacosanol might be considered as a candidate agent for clinical application in treating Parkinson's disease.Tao Wang Yanyong Liu Nan Yang Chao Ji Piu Chan Pingping Zuo 2012Neural Regeneration Research2012,7,14:7

3Accurate machine learning models based on small dataset of energetic materials through spatial matrix featurization methods显示文摘A large database is desired for machine learning(ML) technology to make accurate predictions of materials physicochemical properties based on their molecular structure.When a large database is not available,the development of proper featurization method based on physicochemical nature of target proprieties can improve the predictive power of ML models with a smaller database.In this work,we show that two new featurization methods,volume occupation spatial matrix and heat contribution spatial matrix,can improve the accuracy in predicting energetic materials' crystal density(ρ_(crystal)) and solid phase enthalpy of formation(H_(f,solid)) using a database containing 451 energetic molecules.Their mean absolute errors are reduced from 0.048 g/cm~3 and 24.67 kcal/mol to 0.035 g/cm~3 and 9.66 kcal/mol,respectively.By leave-one-out-cross-validation,the newly developed ML models can be used to determine the performance of most kinds of energetic materials except cubanes.Our ML models are applied to predict ρ_(crystal) and H_(f,solid) of CHON-based molecules of the 150 million sized PubChem database,and screened out 56 candidates with competitive detonation performance and reasonable chemical structures.With further improvement in future,spatial matrices have the potential of becoming multifunctional ML simulation tools that could provide even better predictions in wider fields of materials science.Chao Chen Danyang Liu Siyan Deng Lixiang Zhong Serene Hay Yee Chan Shuzhou Li Huey Hoon Hng 2021Journal of Energy Chemistry2021,30,12:4
4Continuous and comprehensive atmospheric observations in Beijing:a station to understand the complex urban atmospheric environment显示文摘Due to profound impact on climate and human health,air quality has attracted attention from all levels of the civil society.The key step in the provision of required tools for the society to tackle the complex air quality problem is to characterize it in a comprehensive manner with a long-term perspective.Here,we describe a continuous and comprehensive observation station and its accompanying state-ofthe-art instrumentation that was established to investigate the complex urban atmospheric environment in a rapidly developing Chinese Megacity.The station,located in downtown Beijing,aims to study air quality by identifying the major atmospheric pollutants and key processes determining their formation and loss mechanisms.A few hundreds of parameters are continuously measured with the state-of-the-art instruments,including trace gas concentrations,aerosol particle size distributions,and mass concentrations,covering aerosol particle chemical composition from molecules to micrometer-sized aerosol particles.This produced long-term,comprehensive big data with around 1�10^(11)bytes per year.In this paper,we provide an overview on the facilities of the station,the instrumentation used,the workflow of continuous observations and examples of results from 2018 to 2019 and a basis for establishing a modern long-term,comprehensive atmospheric urban observation station in other megacities.Yongchun Liu Chao Yan Zemin Feng Feixue Zheng Xiaolong Fan Yusheng Zhang Chang Li Ying Zhou Zhuohui Lin Yishou Guo Ying Zhang Li Ma Wenshuo Zhou Zhikun Liu Lubna Dada Kaspar Dallenbach Jenni Kontkanen Runlong Cai Tommy Chan Biwu Chu Wei Du Lei Yao Yonghong Wang Jing Cai Juha Kangasluoma Tom Kokkonen Joni Kujansuu Anton Rusanen Chenjuan Deng Yueyun Fu Rujing Yin Xiaoxiao Li Yiqun Lu Yiliang Liu Chaofan Lian Dongsen Yang Weigang Wang Maofa Ge Yuesi Wang Douglas R.Worsnop Heikki Junninen Hong He Veli-Matti Kerminen Jun Zheng Lin Wang Jingkun Jiang Tuukka Petaja Federico Bianchi Markku Kulmala 2020Big Earth Data2020,4,3:3
5Peptide-based pan-CoV fusion inhibitors maintain high potency against SARS-CoV-2 Omicron variant显示文摘Dear Editor,Most recently,a new SARS-CoV-2 variant of concern(VOC)Z Omicron(B.1.1.529),was first reported to the World Health Organization(WHO)from South Africa and then quickly spread to many countries,1,2 posing a serious threat to current vaccine prevention and antibody therapeutic strategies.Several studies have reported that the Omicron variant successfully escapes from neutralizing antibodies elicited by COVID-19 vaccines or from COVID-19 convalescent patients.Shuai Xia Jasper Fuk-Woo Chan Lijue Wang Fanke Jiao Kenn Ka-Heng Chik Hin Chu Qiaoshuai Lan Wei Xu Qian Wang Chao Wang Kwok-Yu ng Yuen Lu Lu Shibo Jiang 2022Cell Research2022,32,4:2
6Sequential activation of uterine epithelial IGF1R by stromal IGF1 and embryonic IGF2 directs normal uterine preparation for embryo implantation显示文摘Embryo implantation in both humans and rodents is initiated by the attachment of a blastocyst to the uterine epithelium.For blastocyst attachment,the uterine epithelium needs to transform at both the structural and molecular levels first,and then initiate the interaction with trophectoderm.Any perturbation during this process will result in implantation failure or long-term adverse pregnancy outcomes.Endocrine steroid hormones,which function through nuclear receptors,combine with the local molecules produced by the uteri or embryo to facilitate implantation.The insulin-like growth factor(IGF)signaling has been reported to play a vital role during pregnancy.However,its physiological function during implantation remains elusive.This study revealed that mice with conditional deletion of Igflr gene in uteri suffered from subfertility,mainly due to the disturbed uterine receptivity and abnormal embryo implantation.Mechanistically,we uncovered that in response to the nidatory estrogen on D4 of pregnancy,the epithelial IGF1R,stimulated by the stromal cell-produced IGF1,facilitated epithelial STAT3 activation to modulate the epithelial depolarity.Furthermore,embryonic derived IGF2 could activate both the epithelial ERK1/2 and STAT3 signaling through IGF1R,which was critical for the transcription of Cox2 and normal attachment reaction.In brief,our data revealed that epithelial IGF1R was sequentially activated by the uterine stromal IGF1 and embryonic IGF2 to guarantee normal epithelium differentiation during the implantation process.Chan Zhou Meiying Lv Peike Wang Chuanhui Guo Zhangli Ni Haili Bao Yedong Tang Han Cai Jinhua Lu Wenbo Deng Xiaoyu Yang Guoliang Xia Haibin Wang Chao Wang Shuangbo Kong 2021Journal of Molecular Cell Biology2021,13,9:2
