1The impacts of conservation agriculture on crop yield in China depend on specific practices, crops and cropping regions显示文摘For smooth and wide application of conservation agriculture(CA), remaining uncertainties about its impacts on crop yield need to be reduced. Based on previous field experiments in China, a meta-analysis was performed to quantify the actual impacts of CA practices(NT: no/reduced-tillage only, CTSR: conventional tillage with straw retention, NTSR: NT with straw retention) on crop yields as compared to conventional tillage without straw retention(CT).Although CA practices increased crop yield by 4.6% on average, there were large variations in their impacts. For each CA practice, CTSR and NTSR significantly increased crop yield by 4.9%and 6.3%, respectively, compared to CT. However, no significant effect was found for NT. Among ecological areas, significant positive effects of CA practices were found in areas with an annual precipitation below 600 mm. Similar effects were found in areas with annual mean air temperature above 5 °C. For cropping regions, CA increased crop yield by 6.4% and 5.5%compared to CT in Northwest and South China, respectively, whereas no significant effects were found in the North China and Northeast China regions. Among crops, the positive effects of CA practices were significantly higher in maize(7.5%) and rice(4.1%) than in wheat(2.9%). NT likely decreased wheat yield. Our results indicate that there are great differences in the impacts of CA practices on crop yield, owing to regional variation in climate and crop types. CA will most likely increase maize yield but reduce wheat yield. It is strongly recommended to apply CA with crop straw retention in maize cropping areas and seasons with a warm and dry climate pattern.Chengyan Zheng Yu Jiang Changqing Chen Yanni Sun Jinfei Feng Aixing Deng Zhenwei Song Weijian Zhang 2014The Crop Journal2014,2,5:15
2Response of grain yield to plant density and nitrogen rate in spring maize hybrids released from 1970 to 2010 in Northeast China显示文摘The objective of this study was to identify the response of grain yield to plant density and nitrogen rate in spring maize hybrids released from 1970 to 2010 and grown extensively in Northeast China.Twenty-one hybrids were grown for 2 years in Northeast China at densities of 30,000,52,500,75,000,and 97,500 plants ha^(-1)and N application levels of 0,150,300,and 450 kg N ha^(-1).Irrespective of density or nitrogen application rate,grain yields both per plant and per unit area were significantly higher for newer than older hybrids.As plant density increased from 30,000 to 97,500 plant ha^(-1),yield per plant of 1970 s,1980 s,1990 s,and 2000 s hybrids decreased by 50%,45%,46%,and 52%,respectively.The response of grain yield per unit area to plant density was curvilinear.The estimated optimum plant densities were about 58,000,49,000,65,000,and 65,000 plants ha^(-1)for hybrids released in the 1970 s,1980s,1990 s,and 2000 s,respectively.The theoretical optimum densities for the hybrids released from the 1970 s to the 2000 s increased by 1750 plants ha^(-1)decade^(-1).Nitrogen fertilization significantly increased grain yields per plant and per unit area for all hybrids.The theoretical optimum N application rates for high yield for hybrids released in the 1970 s and 1980 s were about 280 and 360 kg ha^(-1),and the hybrids from the 1990 s and 2000 s showed highest yield at 330 kg ha^(-1)N.No significant difference in the grain yields of 2000 s hybrids between the N levels of 150 to 450 kg ha^(-1)was found.Significant yield gains per plant and per unit area were found,with average increases of 17.9 g plant^(-1)decade^(-1)and936 kg ha^(-1)decade^(-1)over the period 1970–2010,respectively.Yield gains were attributed mainly to increased yield per plant,contributed by increases in kernel number per ear and1000-kernel weight.The rates of lodging and barren plants of newer hybrids were significantly lower than those of older ones,especially at high plant density.Chunrong Qian Yang Yu Xiujie Gong Yubo Jiang Yang Zhao Zhongliang Yang Yubo Hao Liang Li Zhenwei Song Weijian Zhang 2016The Crop Journal2016,4,6:15
3Nuclear Aurora kinase A switches m^(6)A reader YTHDC1 to enhance an oncogenic RNA splicing of tumor suppressor RBM4显示文摘Aberrant RNA splicing produces alternative isoforms of genes to facilitate tumor progression,yet how this process is regulated by oncogenic signal remains largely unknown.Here,we unveil that non-canonical activation of nuclear AURKA promotes an oncogenic RNA splicing of tumor suppressor RBM4 directed by m^(6)A reader YTHDC1 in lung cancer.Nuclear translocation of AURKA is a prerequisite for RNA aberrant splicing,specifically triggering RBM4 splicing from the full isoform(RBM4-FL)to the short isoform(RBM4-S)in a kinase-independent manner.SiSi Li YangFan Qi JiaChuan Yu YuChao Hao Bin He MengJuan Zhang ZhenWei Dai TongHui Jiang SuYi Li Fang Huang Ning Chen Jing Wang MengYing Yang DaPeng Liang Fan An JinYao Zhao WenJun Fan YuJia Pan ZiQian Deng YuanYuan Luo Tao Guo Fei Peng ZhiJie Hou ChunLi Wang FeiMeng Zheng LingZhi Xu Jie Xu QingPing Wen BiLian Jin Yang Wang Quentin Liu 2022Signal Transduction and Targeted Therapy2022,7,5:4
4Synthesis and Characterization of Disodium Hydrogen Phosphate Dodecahydrate-Lauric-Palmitic Acid Used for Indoor Energy Storage Floor Units显示文摘Organic and inorganic phase change materials(PCMs) are considered potential materials for thermal energy storage(TES) with different phase change characteristics. In this study, a novel organic-inorganic composite phase change material(PCM) called disodium hydrogen phosphate dodecahydrate-lauric-palmitic acid(D-LA-PACM) was prepared. Expanded graphite(EG) was selected as the support material, and the novel organic-inorganic form-stable PCM called D-LA-PAPCM/EG was prepared using the vacuum adsorption method. Differential scanning calorimetry, Fourier transform infrared spectroscopy, X-ray diffraction, leakage testing, melting and solidification cycle testing, thermal conductivity testing, scanning electron microscopy observation of the micromorphology, and other characterization methods were used to study the microstructure and morphology, thermal physical parameters, thermal conductivity, stability of the PCMs, and the comprehensive material properties of D-LA-PAPCM under the composite action of EG. Results indicated that the melting and freezing temperatures and latent heats of D-LA-PAPCM/EG were measured to be 31.6℃ and 34.3℃ and 142.9 and 142.8 J/g, respectively. Although some of the lauric-palmitic acid(LA-PA) and disodium hydrogen phosphate dodecahydrate(DHPD) separated in the multiple porous structures of EG after 1000 cycles, they could still absorb and release latent heats independently, with D-LA-PAPCM/EG still exhibiting good thermal stability. The thermal conductivity of D-LA-PAPCM/EG was 1.361 W/(m·K). Therefore, the material and thermal properties of the prepared D-LA-PAPCM/EG indicate that it could be well used as a feasible material for energy-saving phase change floor units in indoor TES systems.XU Qian AKKURT Nevzat ZOU Zhenwei LIU Yang FENG Junxiao YU Chuqiao DING Chong XIONG Yaxuan ZHOU Jingzhi ZANG Yong DING Yulong 2020Journal of Thermal Science2020,29,2:4
5Voltage-induced penetration effect in liquid metals at room temperature显示文摘Room-temperature liquid metal is discovered to be capable of penetrating through macro-and microporous materials by applying a voltage.The liquid metal penetration effects are demonstrated in various porous materials such as tissue paper;thick and fine sponges;fabrics;and meshes.The underlying mechanism is that the high surface tension of liquid metal can be significantly reduced to near-zero due to the voltage-induced oxidation of the liquid metal surface in a solution.It is the extremely low surface tension and gravity that cause the liquid metal to superwet the solid surface^leading to the penetration phenomena.These findings offer new opportunities for novel microfluidic applications and could promote further discovery of more exotic fluid states of liquid metals.Frank F Yun Zhenwei Yu Yahua He Lei Jiang Zhao Wang Haoshuang Gu Xiaolin Wang 2020National Science Review2020,7,2:3

7Chinese consensus guidelines for therapeutic drug monitoring of polymyxin B,endorsed by the Infection and Chemotherapy Committee of the Shanghai Medical Association and the Therapeutic Drug Monitoring Committee of the Chinese Pharmacological Society显示文摘Polymyxin B,which is a last-line antibiotic for extensively drug-resistant Gram-negative bacterial infections,became available in China in Dec.2017.As dose adjustments are based solely on clinical experience of risk toxicity,treatment failure,and emergence of resistance,there is an urgent clinical need to perform therapeutic drug monitoring(TDM)to optimize the use of polymyxin B.It is thus necessary to standardize operating procedures to ensure the accuracy of TDM and provide evidence for their rational use.We report a consensus on TDM guidelines for polymyxin B,as endorsed by the Infection and Chemotherapy Committee of the Shanghai Medical Association and the Therapeutic Drug Monitoring Committee of the Chinese Pharmacological Society.The consensus panel was composed of clinicians,pharmacists,and microbiologists from different provinces in China and Australia who made recommendations regarding target concentrations,sample collection,reporting,and explanation of TDM results.The guidelines provide the first-ever consensus on conducting TDM of polymyxin B,and are intended to guide optimal clinical use.XIAOFEN LIU CHENRONG HUANG PHILLIP JBERGEN JIAN LI JINGJING ZHANG YIJIAN CHEN YONGCHUAN CHEN BEINING GUO FUPIN HU JINFANG HU LINLIN HU XIN LI HONGQIANG QIU HUA SHAO TONGWEN SUN YU WANG PING XU JING YANG YONG YANG ZHENWEI YU BIKUI ZHANG HUAIJUN ZHU XIAOCONG ZUO YI ZHANG LIYAN MIAO JING ZHANG 2023Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023,24,2:1

11High-Performance Blue Quasi-2D Perovskite Light-Emitting Diodes via Balanced Carrier Confinement and Transfer显示文摘Extensive investigation of the passivating agents has been performed to suppress the perovskite defects.However,very few attentions have been paid to rationally design the passivating agents for the balance of the carrier confinement and transfer in quasi-2D perovskites,which is essential to achieve high-performance perovskite LEDs(PeLEDs).In this work,tributylphosphine oxide(TBPO)with moderate carbon chain length is demonstrated as a decent passivator for the quasi-2D perovskites by strengthening the carrier confinement for massive radiative recombination within the perovskites,and more importantly providing efficient carrier transfer in the quasi-2D perovskites.Benefiting from these interesting optoelectronic properties of TBPO-incorporated perovskites,we achieve high-efficient blue PeLEDs with an external quantum efficiency up to 11.5%and operational stability as long as 41.1 min without any shift of the electroluminescence spectra.Consequently,this work contributes an effective approach to promote the carrier confinement and transfer for high-performance and stable blue PeLEDs.Zhenwei Ren Jiayun Sun Jiahao Yu Xiangtian Xiao Zhaojin Wang Ruijia Zhang Kai Wang Rui Chen Yu Chen Wallace C.H.Choy 2022Nano-Micro Letters2022,14,4:1

13Mitogenomic Conservation Genetics of the Critically Endangered Liaoning Clawed Salamander显示文摘The Liaoning clawed salamander(Onychodactylus zhaoermii)is an endemic and critically endangered amphibian species of China.To study the population genetics of natural populations of this species,32 samples were collected from six different locations,and the mitochondrial genome was sequenced.Population genetic analyses showed that the Liaoning clawed salamander is composed of only one radialized cluster with ultralow nucleotide diversity.Late Pleistocene climate cooling(-100 to-30 kya)may have reduced the effective population size of the Liaoning clawed salamander,and the subsequent temperature increase(~25 kya to present)provided the opportunity for population expansion.Because of heat sensitivity,the maximum temperature of the prebreeding period,especially from March to May,is very important for the surface environment living in the Liaoning clawed salamander.Three suitable regions were predicted by the MaxEnt model,and the largest suitable region(approximately 899 km2)was at the four-county boundary area and was larger than the present’Natural Conservation Community of the Liaoning Clawed Salamander’.To ensure more effective protection of all Liaoning clawed salamanders,we suggest extending the current’Natural Conservation Community of the Liaoning Clawed Salamander’to include the four-county boundary area.Yu ZHOU Boyang YU Jichuan ZHAO Fang WANG Zhenwei WANG Bingjun DONG Baotian YANG 2021Asian Herpetological Research2021,12,4:1
14Bromodomain-containing proteins BRD1, BRD2, and BRD13 are core subunits of SWI/SNF complexes and vital for their genomic targeting in Arabidopsis显示文摘Switch defective/sucrose non-fermentable(SWI/SNF)chromatin remodeling complexes are multi-subunit machines that play vital roles in the regulation of chromatin structure and gene expression.However,the mechanisms by which SWI/SNF complexes recognize their target loci in plants are not fully understood.Here,we show that the Arabidopsis thaliana bromodomain-containing proteins BRD1,BRD2,and BRD13 are core subunits of SWI/SNF complexes and critical for SWI/SNF genomic targeting.These three BRDs interact directly with multiple SWI/SNF subunits,including the BRAHMA(BRM)catalytic subunit.Phenotypic and transcriptomic analyses of the brd1 brd2 brd13 triple mutant revealed that these BRDs act largely redundantly to control gene expression and developmental processes that are also regulated by BRM.Genome-wide occupancy profiling demonstrated that these three BRDs extensively colocalize with BRM on chromatin.Simultaneous loss of function of three BRD genes results in reduced BRM protein levels and decreased occupancy of BRM on chromatin across the genome.Furthermore,we demonstrated that the bromodomains of BRDs are essential for genomic targeting of the BRD subunits of SWI/SNF complexes to their target sites.Collectively,these results demonstrate that BRD1,BRD2,and BRD13 are core subunits of SWI/SNF complexes and reveal their biological roles in facilitating genomic targeting of BRM-containing SWI/SNF complexes in plants.Yaoguang Yu Wei Fu Jianqu Xu Yawen Lei Xin Song Zhenwei Liang Tao Zhu Yuhui Liang Yuanhao Hao Liangbing Yuan Chenlong Li 2021Molecular Plant2021,14,6:1

18立即全切与保留膀胱治疗初发T1G3膀胱癌总生存率的Meta分析(英文)显示文摘Objective:The aim of this study was to compare the therapeutic effects of bladder preserving approach transurethral resection (TURBT) with additional intravesical instillation versus immediate cystectomy in patients with newly diagnosed stage T 1 G 3 bladder cancer. Methods:Clinical data of patients with newly diagnosed T 1 G 3 bladder cancer underwent immediate cystectomy (Group A) or TURBT with additional intravesical instillation (Group B) was collected from online databases. Meta-analysis that recommended by Cochrane Collaboration was done for the data obtained. Publication bias was examined using a funnel plot. Results:Four trails, including 434 patients, were eligible for this study. The general mortality rate of group A (74/149 = 49.7%) and group B (102/285 = 35.8%) was calculated and compared in RevMan 4.2, which showed the difference on general mortality rate between the two groups was not statistical significant, with the pooled RR = 1.23 (95% CI 1.10-1.70, P > 0.05). Conclusion:Compared with TURBT, immediate cystectomy may not reduce the general mortality rate to improve the forward survival rate.Liang Yu Yanjiang Li Zhenwei Zhao Ran Cai 2013The Chinese-German Journal of Clinical Oncology2013,12,5:0

20All-dielectric metasurface for fully resolving arbitrary beams on a higher-order Poincaré sphere显示文摘Characterizing the amplitude, phase profile, and polarization of optical beams is critical in modern optics. With a series of cascaded optical components, one can accurately resolve the optical singularity and polarization state in traditional polarimetry systems. However, complicated optical setups and bulky configurations inevitably hinder future applications for integration. Here, we demonstrate a metadevice that fully resolves arbitrary beams on a higher-order Poincaré sphere(HOPS) via a single-layer all-silicon metasurface. The device is compact and capable of detecting optical singularities and higher-order Stokes parameters simultaneously through a single intensity measurement. To verify the validity of the proposed metadevice, different beams on HOPS0,0 and HOPS1,-1 are illuminated on the metadevices. The beams are fully resolved, and the reconstructed higher-order Stokes parameters show good agreement with the original ones. Taking the signal-to-noise ratio into account, the numerical simulations indicate that the design strategy can be extended to fully resolve arbitrary beams on HOPS with order up to 4. Because of the advantages of compact configuration and compatibility with current semiconductor technology, the metadevice will facilitate potential applications in information processing and optical communications.Hui Yang Zhenwei Xie Guanhai Li Kai Ou Feilong Yu Hairong He Hong Wang Xiaocong Yuan 2021Photonics Research2021,9,3:0
