1Genome survey uncovers the secrets of sex and lifestyle in caterpillar fungus显示文摘The caterpillar fungus Ophiocordyceps sinensis (best known as Cordyceps sinensis) mummifies ghost moth larvae exclusively in Tibetan Plateau alpine ecosystems. Touted as 'Himalayan Viagra', the fungus is highly prized due to its medical benefits and dwindling supplies. Attempts to culture the sexual fruiting-body have failed and the huge market demand has led to severe devastation of local ecosystems and to the fungus heading towards extinction. By genome sequencing, we establish that unlike related insect pathogens O. sinensis contains two compatible mating-type genes in its genome and is self-fertile, i.e. homothallic. However, sexual processes are only initiated under native environmental conditions. O. sinensis resembles biotrophic plant pathogens in having a genome shaped by retrotransposon-driven expansions. The resulting changes in gene content suggest that O. sinensis has a biphasic pathogenic mechanism beginning with stealth pathogenesis in early host instars. O. sinensis is the first psychrophilic fungus sequenced and is adapted to extreme cold with putative antifreeze proteins and mechanisms for increasing lipid accumulation and fatty acid unsaturation. We hypothesize that for the inbreeding O. sinensis the massive proliferation of retrotransposons provides a tradeoff between the advantages of increased genetic variation independent of sexual recombination and deletion of genes dispensable for its specialized pathogenic lifestyle.HU Xiao ZHANG YongJie XIAO GuoHua ZHENG Peng XIA YongLiang ZHANG XingYu ST LEGER Raymond J LIU XingZhong WANG ChengShu 2013Chinese Science Bulletin2013,58,23:26
2The historical and current research progress on jujube–a superfruit for the future显示文摘Jujube(Ziziphus jujuba Mill.),or Chinese date,is the most important species of Rhamnaceae,a large cosmopolitan family,and is one of the oldest cultivated fruit trees in the world.It originates from the middle and lower reaches of the Yellow River,the‘mother river’of the Chinese people.It is distributed in at least 48 countries on all continents except Antarctica and is becoming increasingly important,especially in arid and semiarid marginal lands.Based on a systematic analysis of the unique characteristics of jujube,we suggest that it deserves to be recognized as a superfruit.We summarized historical research achievements from the past 3000 years and reviewed recent research advances since 1949 in seven fields,including genome sequencing and application,germplasm resources and systematic taxonomy,breeding and genetics,cultivation theory and techniques,pest control,postharvest physiology and techniques,and nutrition and processing.Based on the challenges facing the jujube industry,we discuss eight research aspects to be focused on in the future.Mengjun Liu Jiurui Wang Lili Wang Ping Liu Jin Zhao Zhihui Zhao Shengrui Yao Florin Stănică Zhiguo Liu Lixin Wang Changwei Ao Li Dai Xiansong Li Xuan Zhao Chunxiang Jia 2020Horticulture Research2020,7,1:10
3Recent advances in non-metal doped titania for solar-driven photocatalytic/photoelectrochemical water-splitting显示文摘Photocatalytic (PC) / Photoelectrochemical (PEC) water splitting under solar light irradiation is considered as a prospective technique to support the sustainable and renewable H_(2) economy and to reach the ultime goal of carbon neutral. TiO_(2) based photocatalysts with high chemical stability and excellent photocatalytic properties have great potential for solar-to-H_(2) conversion. To conquer the challenges of the large band-gap and rapid recombination of photo generated electron-holepairs in TiO_(2), non-metal doping turns out to be economic, facile, and effective on boosting the visible light activity. The localized defect states such as oxygen vacancy and Ti^(3+) generated by non-metal doping are located in the band-gap of TiO_(2), which result in the reduction of band-gap, thus a red-shift of the absorption edge. The hetero doping atoms such as B^(3+), I^(7+), S^(4+)/S^(6+), P^(5+) can also act as electron donors or trap sites which facilitate the charge carrier separation and suppress the recombination of electron-hole pairs. In this comprehensive review, we present the most recent advances on non-metal doped TiO_(2) photocatalysts in terms of fundamental aspects, origin of visible light activity and the PC / PEC behaviours for water splitting. In particular, the characteristics of different non-metal elements (N, C, B, S, P, Halogens) as dopants are discussed in details focusing on the synthesis approaches, characterization as well as the efficiency of PC and PEC water splitting. The present review aims at guiding the readers who want quick access to helpful information about how to efficiently improve the performance of photocatalysts by simple doping strategies and could stimulate new intuitive into the new doping strategies.Ying-Ying Wang Yan-Xin Chen Tarek Barakat Yu-Jia Zeng Jing Liu Stéphane Siffert Bao-Lian Su 2022Journal of Energy Chemistry2022,31,3:4

5Comprehensive evaluation of mechanism of 'chimney effect' using principles of magnetism, geochemistry and mineralogy显示文摘Study of forming mechanism of 'chimney-effect' (CE) has important significance for basic theory and applications of non-seismic geophysical and geochemical methods locating oil/gas reservoirs. The theoretical basis of comprehensive evaluation of mechanism of CE using principles of magnetism, geochemistry and mineralogy has been reviewed, with the problems to be solved: (ⅰ) study for the relationship between process of oil/gas migration and geochemical field; (ⅱ) analysis of genesis of magnetic, geochemical and mineralogical anomaly; (ⅲ) interpretation of surface soil magnetism and geochemical anomaly combined with seismic data.LIU Qingsheng 1, CHENG Tongjin 2 and LIU Shugen 3 1.

6Noncontrast-enhanced MRI-based Noninvasive Score for Portal Hypertension(CHESS1802):An International Multicenter Study显示文摘Background and Aims:This study aimed to determine the performance of the non-invasive score using noncontrastenhanced MRI(CHESS-DIS score)for detecting portal hy-pertension in cirrhosis.Methods:In this international multicenter,diagnostic study(ClinicalTrials.gov,NCT03766880),patients with cirrhosis who had hepatic venous pressure gradient(HVPG)measurement and noncontrast-enhanced MRI were prospectively recruited from four university hospitals in China(n=4)and Turkey(n=1)between December 2018 and April 2019.A cohort of patients was retrospectively recruited from a university hospital in Italy between March 2015 and November 2017.After segmentation of the liver on fat-suppressed T1-weighted MRI maps,CHESS-DIS score was calculated automatically by an in-house developed code based on the quantification of liver surface nodularity.Results:A total of 149 patients were included,of which 124 were from four Chinese hospitals(training cohort)and 25 were from two international hospitals(validation cohort).A positive correlation between CHESS-DIS score and HVPG was found with the correlation coefficients of 0.36(p<0.0001)and 0.55(p<0.01)for the training and validation cohorts,respectively.The area under the receiver operating characteristic curve of CHESS-DIS score in detection of clinically significant portal hypertension(CSPH)was 0.81 and 0.9 in the training and validation cohorts,respectively.The intra-class correlation coefficients for assessing the inter-and intra-observer agreement were 0.846 and 0.841,respectively.Conclusions:A non-invasive score using noncontrast-enhanced MRI was developed and proved to be significantly correlated with invasive HVPG.Besides,this score could be used to detect CSPH in patients with cirrhosis.Yanna Liu Tianyu Tang NecatiÖrmeci Yifei Huang Jitao Wang Xiaoguo Li Zhiwei Li Weimin An Dengxiang Liu Chunqing Zhang Changchun Liu Jinqiang Liu Chuan Liu Guangchuan Wang Cristina Mosconi Alberta Cappelli Antonio Bruno Seray Akçalar EmrecanÇelebioğlu EvrenÜstüner Sadık Bilgiç Zeynep Ellik ÖzgünÖmer Asiller Lei Li Haijun Zhang Ning Kang Dan Xu Ruiling He Yan Wang Yang Bu Ye Gu Shenghong Ju Rita Golfieri Xiaolong Qi 2021Journal of Clinical and Translational Hepatology2021,9,6:3
7Onboard GRB trigger algorithms of SVOM-GRM显示文摘The Gamma-Ray Monitor(GRM)is a high energy detector onboard the future Chinese-French satellite named the Space-based multi-band astronomical Variable Object Monitor which is dedicated to studies of gamma-ray bursts(GRBs).This paper presents an investigation of the algorithms that look for GRBs by searching for a significant increase in the photon count rate for the computer onboard GRM.The trigger threshold and trigger efficiency,which are based on a given sample of GRBs,are calculated with the algorithms.The trigger characteristics of onboard instruments GRM and ECLAIRs are also analyzed.In addition,the impact of solar flares on GRM is estimated,and a method to distinguish solar flares from GRBs is investigated.Dong-Hua Zhao Bo-Bing Wu Li-Ming Song Yong-Wei Dong Stphane Schanne Bertrand Cordier Jiang-Tao Liu 2013Research in Astronomy and Astrophysics2013,13,11:2
