| 1 | Grey matter volume abnormalities in patients with bipolar I depressive disorder and unipolar depressive disorder:a voxelbased morphometry study显示文摘Bipolar disorder and unipolar depressive disorder(UD) may be different in brain structure. In the present study,we performed voxel-based morphometry(VBM) to quantify the grey matter volumes in 23 patients with bipolar I depressive disorder(BP1) and 23 patients with UD,and 23 age-,gender-,and educationmatched healthy controls(HCs) using magnetic resonance imaging. We found that compared with the HC and UD groups,the BP1 group showed reduced grey matter volumes in the right inferior frontal gyrus and middle cingulate gyrus,while the UD group showed reduced volume in the right inferior frontal gyrus compared to HCs. In addition,correlation analyses revealed that the grey matter volumes of these regions were negatively correlated with the Hamilton depression rating scores. Taken together,the results of our study suggest that decreased grey matter volume of the right inferior frontal gyrus is a common abnormality in BP1 and UD,and decreasedgrey matter volume in the right middle cingulate gyrus may be specifi c to BP1. | Yi Cai Jun Liu Li Zhang Mei Liao Yan Zhang Lifeng Wang Hongjun Peng Zhong He Zexuan Li Weihui Li Shaojia Lu Yuqiang Ding Lingjiang Li | 2015 | Neuroscience Bulletin2015，31，1： | 11 |
| 2 | Developing controllable hypermutable Clostridium cells through manipulating its methyl-directed mismatch repair system显示文摘Development of controllable hypermutable cells can greatly benefit understanding and harnessing microbial evolution.However,there have not been any similar sys-tems developed for Clostridium,an important bacterial genus.Here we report a novel two-step strategy for de-veloping controllable hypermutable cells of Clostridium acetobutylicum,an important and representative indus-trial strain.Firstly,the mutS/L operon essential for methyl-directed mismatch repair(MMR)activity was inactivated from the genome of C.acetobutylicum to generate hy-permutable cells with over 250-fold increased mutation rates.Secondly,a proofreading control system carrying an inducibly expressed mutS/L operon was constructed.The hypermutable cells and the proofreading control system were integrated to form a controllable hypermut-able system SMBMutC,of which the mutation rates can be regulated by the concentration of anhydrotetracycline(aTc).Duplication of the miniPthl-tetR module of the proof-reading control system further signifi cantly expanded the regulatory space of the mutation rates,demonstrating hypermutable Clostridium cells with controllable mutation rates are generated.The developed C.acetobutylicum strain SMBMutC2 showed higher survival capacities than the control strain facing butanol-stress,indicating greatly increased evolvability and adaptability of the controllable hypermutable cells under environmental challenges. | Guodong Luan Zhen Cai Fuyu Gong Hongjun Dong Zhao Lin Yanping Zhang Yin Li | 2013 | Protein & Cell2013，4，11： | 4 |

| 4 | Electronic structure of exfoliated millimeter-sized monolayer WSe2 on silicon wafer显示文摘The mono layer WSe2 is in teresting and important for future application in nanoelectronics,spintronics and valleytronics devices,because it has the largest spin splitting and Ion gest valley coherence time among all the known monolayer transition-metal dichalcogenides(TMDs).Toobtain the large-area monolayer TMDs'crystal is the first step to manu facture scalable and high-performance electronic devices.In this letter,we have successfully fabricated millimeter-sized mono layer WSe2 single crystals with very high quality,based on our improved mecha nicalexfoliation method.With such superior samples,using standard high resolution angle-resolved photoemission spectroscopy,we didcomprehe nsive electronic band structure measurements on our mono layer WSe2.The overall band features point it to be a 1.2 eV direct bandgap semico nductor.Its spin splitting of the valence band at K point is found as 460 meV,which is 30 meV less than the corresponding band splitting in its bulk counterpart.The effective hole masses of valence bands are determined as 2.344 me atГ,and 0.529 me as well as 0.532 meat K for the upper and lower branch of splitting ban ds,respectively.And screening effect from substrate is shown to substa ntially impact onthe electronic properties.Our results provide importa nt insights into band structure engineering in mono layer TMDs.Our mono layer WSe2 crystals may constitute a valuable device platform. | Wenjuan Zhao Yuan Huang Cheng Shen Cong Li Yongqing Cai Yu Xu Hongtao Rong Qiang Gao Yang Wang Lin Zhao Lihong Bao Qingyan Wang Guangyu Zhang Hongjun Gao Zuyan Xu Xingjiang Zhou Guodong Liu | 2019 | Nano Research2019，12，12： | 2 |

| 7 | The Relationship Between Stomatal Movement and Light Intensity Gradient in Three Dendrobium Species Compared with Typical CAM Plants显示文摘There is a close relationship between crassulacean acid metabolism and drought tolerance,and a great number of landscape plants which consume less water are necessary to build economic garden.In order to provide the basis for selecting drought-tolerant landscape plants,five species of plants were employed,including Dendrobium chrysotoxum,D.nobile,D.primulinum,Kalanchoblossfeldiana and K.daigremontiana.Exposed to different intensities of light,various samples were collected.The slices were prepared via different techniques.Stomatal movements and stomatal complex structures were observed by scanning electronic microscope and confocal laser scanning microscope.The results indicated that the slices made rapidly from fresh leaves were conductive to inspecting actual stomatal movements and stomatal complex structures as soon as possible.It was found that the stomatal movement of K.daigremontiana,K.blossfeldiana and D.primulinum displayed typical characteristics of crassulacean acid metabolism,while that of D.chrysotoxum and D.nobile did not exhibited obvious characteristics of crassulacean acid metabolism. | Jianwu REN Bin CAI Xiangwei HE Hongjun YAO Shengjie DU Fengnan SHANG | 2015 | Agricultural Biotechnology2015，4，2： | 0 |
