1Experimental study on the mechanical properties and consolidation mechanism of microbial grouted backfill显示文摘Backfill mining technology is the practice of returning waste materials underground for both disposal and geotechnical stability,however,a challenge with current technologies is that they commonly require cement-based binders which have a relatively high environmental impact.Finding alternatives to cement-based binders can improve environmental performance and this paper proposes microbial grouted backfill(MGB)as a potential solution.In this paper,the effects of the cementation solution concentration(CSC),volume ratio of bacterial solution to cementation solution(VRBC),particle sizes of the aggregates,and the number of grouting batches on the mechanical properties of MGB are studied.The experimental results show that MGB strength increased,up to a peak value,as CSC was increased,before decreasing as CSC was increased further.The results also show that MGB strength increased,up to a peak value,as VRBC decreased,before decreasing as the VRBC was decreased further.The peak strength was achieved at a CSC of 2 mol/L and a VRBC of 1:9.The strength of the MGB also increased as the number of grouting batches increased.Graded MGB samples showed the highest UCS,25.12 MPa,at particle sizes of 0.2 to 0.8 mm,while full(non-graded)MGB samples displayed mean UCS values ranging from1.56 MPa when the maximum particle size was 0.2 mm,up to 13 MPa when the maximum particle size was 1.2 mm.MGB samples are consolidated by the calcium carbonate that is precipitated during microbial metabolism,and the strength of MGB increases linearly as calcium carbonate content increases.The calcium carbonate minerals produced in MGB materials are primarily calcite,with secondary amounts of vaterite.Xuejie Deng Yu Li Fei Wang Xiaoming Shi Yinchao Yang Xichen Xu Yanli Huang Benjamin de Wit 2022International Journal of Mining Science and Technology2022,32,2:7
2New developments in immunotherapy for lymphoma显示文摘The development of immunotherapies for lymphoma has undergone a revolutionary evolution over the past decades. Since the advent of rituximab as the first successful immunotherapy for B-cell non-Hodgkin lymphoma over two decades ago, a plethora of new immunotherapeutic approaches to treat lymphoma has ensued. Four of the most exciting classes of immunotherapies include:chimeric antigen receptor T-cells, bispecific antibodies, immune checkpoint inhibitors, and vaccines. However, with addition of these novel therapies the appropriate timing of treatment, optimal patient population, duration of therapy, toxicity, and cost must be considered. In this review, we describe the most-promising immunotherapeutic approaches for the treatment of lymphoma in clinical development, specifically focusing on clinical trials performed to date and strategies for improvement.Benjamin Heyman Yiping Yang 2018Cancer Biology & Medicine2018,15,3:6

4Multiple Chromatographic and Chemometric Methods for Quality Standardization of Chinese Herbal Medicines显示文摘Quality standardization of complementary medicine is fundamental for industry and practice as it underpins the quality,safety and efficacy of Chinese herbal medicines.Current herbal standardizations are often based on the quantitative analysis of a single compound,which may not reflect the total characteristic,bioactive and toxic nature of the herbs or products.Therefore,there is a need to establish an internationally recognized methodology for quality standardization of Chinese herbal medicines.The analytical methods reviewed in this article are pharmacognosy,TLC,HPLC,LCMS,CE and chemo-metrics.This article also covers the developments and applications of these methods in quality standardization.Recent advances show that a combination of these methods creates an overall chemical profile of each herb.This is supported by results reviewed in this article and obtained in our laboratory tests on medicinal herbs including Hypericum perforatum,Morinda officinalis and Centella asiatica.Significant variations in active components have been observed between herbal samples and products.It is proposed that the identification of active components,pharmacological activities and eventual clinical applications are required for a comprehensive quality standardization system.Our findings indicate that the combination of various chromatographic and chemometric methods will advance the methodology of quality standardization and enhance the overall confidence in herbal medicine for the health practitioner and the public.Valentina Razmovski-Naumovski Wannit Tongkao-on Benjamin Kimble Vincent L.

6Influence of transboundary air pollution on air quality in southwestern China显示文摘Air pollution is a grand challenge of our time due to its multitude of adverse impacts on environment and society,with the scale of impacts more severe in developing countries,including China.Thus,China has initiated and implemented strict air pollution control measures over last several years to reduce impacts of air pollution.Monitoring data from Jan 2015 to Dec 2019 on six criteria air pollutants(SO_(2),NO_(2),CO,O_(3),PM_(2.5),and PM_(10))at eight sites in southwestern China were investigated to understand the situation and analyze the impacts of transboundary air pollutants in this region.In terms of seasonal variation,the maximum concentrations of air pollutants at these sites were observed in winter or spring season depending on individual site.For diurnal variation,surface ozone peaked in the afternoon while the other pollutants had a bimodal pattern with peaks in the morning and late afternoon.There was limited transport of domestic emissions of air pollutants in China to these sites.Local emissions enhanced the concentrations of air pollutants during some pollution events.Mostly,the transboundary transport of air pollution from South Asia and Southeast Asia was associated with high concentrations of most air pollutants observed in southwestern China.Since air pollutants can be transported to southwestern China over long distances from the source regions,it is necessary to conduct more research to properly attribute and quantify transboundary transport of air pollutants,which will provide more solid scientific guidance for air pollution management in southwestern China.Xiufeng Yin Shichang Kang Maheswar Rupakheti Benjamin de Foy Ping Li Junhua Yang Kunpeng Wu Qianggong Zhang Dipesh Rupakheti 2021Geoscience Frontiers2021,12,6:4
7SHP2 regulates skeletal cell fate by modifying SOX9 expression and transcriptional activity显示文摘Chondrocytes and osteoblasts differentiate from a common mesenchymal precursor, the osteochondroprogenitor(OCP), and help build the vertebrate skeleton. The signaling pathways that control lineage commitment for OCPs are incompletely understood. We asked whether the ubiquitously expressed protein-tyrosine phosphatase SHP2(encoded by Ptpn11) affects skeletal lineage commitment by conditionally deleting Ptpn11 in mouse limb and head mesenchyme using 'Cre-lox P'-mediated gene excision.SHP2-deficient mice have increased cartilage mass and deficient ossification, suggesting that SHP2-deficient OCPs become chondrocytes and not osteoblasts. Consistent with these observations, the expression of the master chondrogenic transcription factor SOX9 and its target genes Acan, Col2a1, and Col10a1 were increased in SHP2-deficient chondrocytes, as revealed by gene expression arrays, q RT-PCR, in situ hybridization, and immunostaining. Mechanistic studies demonstrate that SHP2 regulates OCP fate determination via the phosphorylation and SUMOylation of SOX9, mediated at least in part via the PKA signaling pathway. Our data indicate that SHP2 is critical for skeletal cell lineage differentiation and could thus be a pharmacologic target for bone and cartilage regeneration.Chunlin Zuo Lijun Wang Raghavendra M.Kamalesh Margot E.Bowen Douglas C.Moore Mark S.Dooner Anthony M.Reginato Qian Wu Christoph Schorl Yueming Song Matthew L.Warman Benjamin G.Neel Michael G.Ehrlich Wentian Yang 2018Bone Research2018,6,2:3
8Empirical estimates of regional carbon budgets imply reduced global soil heterotrophic respiration显示文摘Resolving regional carbon budgets is critical for informing land-based mitigation policy.For nine regions covering nearly the whole globe,we collected inventory estimates of carbon-stock changes complemented by satellite estimates of biomass changes where inventory data are missing.The net land–atmospheric carbon exchange(NEE)was calculated by taking the sum of the carbon-stock change and lateral carbon fluxes from crop and wood trade,and riverine-carbon export to the ocean.Summing up NEE from all regions,we obtained a global‘bottom-up'NEE for net land anthropogenic CO_(2)uptake of–2.2±0.6 Pg C yr^(-1)consistent with the independent top-down NEE from the global atmospheric carbon budget during 2000–2009.This estimate is so far the most comprehensive global bottom-up carbon budget accounting,which set up an important milestone for global carbon-cycle studies.By decomposing NEE into component fluxes,we found that global soil heterotrophic respiration amounts to a source of CO_(2)of 39 Pg C yr^(-1)with an interquartile of 33–46 Pg C yr^(-1)—a much smaller portion of net primary productivity than previously reported.Philippe Ciais Yitong Yao Thomas Gasser Alessandro Baccini Yilong Wang Ronny Lauerwald Shushi Peng Ana Bastos Wei Li Peter A.Raymond Josep G.Canadell Glen P.Peters Rob J.Andres Jinfeng Chang Chao Yue A.Johannes Dolman Vanessa Haverd Jens Hartmann Goulven Laruelle Alexandra G.Konings Anthony W.King Yi Liu Sebastiaan Luyssaert Fabienne Maignan Prabir K.Patra Anna Peregon Pierre Regnier Julia Pongratz Benjamin Poulter Anatoly Shvidenko Riccardo Valentini Rong Wang Grégoire Broquet Yi Yin Jakob Zscheischler Bertrand Guenet Daniel SGoll Ashley-P.Ballantyne Hui Yang Chunjing Qiu Dan Zhu 2021National Science Review2021,8,2:3
9A key‘foxy’aroma gene is regulated by homologyinduced promoter indels in the iconic juice grape‘Concord’显示文摘‘Concord’,the most well-known juice grape with a parentage of the North American grape species Vitis labrusca L.,possesses a special‘foxy’aroma predominantly resulted from the accumulation of methyl anthranilate(MA)in berries.This aroma,however,is often perceived as an undesirable attribute by wine consumers and rarely noticeable in the common table and wine grape species V.vinifera.Here we discovered homology-induced promoter indels as a major genetic mechanism for species-specific regulation of a key‘foxy’aroma gene,anthraniloyl-CoA:methanol acyltransferase(AMAT),that is responsible for MA biosynthesis.We found the absence of a 426-bp and/or a 42-bp sequence in AMAT promoters highly associated with high levels of AMAT expression and MA accumulation in‘Concord’and other V.labrusca-derived grapes.These promoter variants,all with direct and inverted repeats,were further confirmed in more than 1,300 Vitis germplasm.Moreover,functional impact of these indels was validated in transgenic Arabidopsis.Superimposed on the promoter regulation,large structural changes including exonic insertion of a retrotransposon were present at the AMAT locus in some V.vinifera grapes.Elucidation of the AMAT genetic regulation advances our understanding of the‘foxy’aroma trait and makes it genetically trackable and amenable in grapevine breeding.Yingzhen Yang JoséCuenca Nian Wang Zhenchang Liang Honghe Sun Benjamin Gutierrez Xiaojun Xi Jie Arro YiWang Peige Fan Jason Londo Peter Cousins Shaohua Li Zhangjun Fei Gan-Yuan Zhong 2020Horticulture Research2020,7,1:3

11结合风险矩阵和故障树分析法的海洋地震测量船运营的规范化安全评估显示文摘In maritime safety research,risk is assessed usually within the framework of formal safety assessment(FSA),which provides a formal and systematic methodology to improve the safety of lives,assets,and the environment.A bespoke application of FSA to mitigate accidents in marine seismic surveying is put forward in this paper,with the aim of improving the safety of seismic vessel operations,within the context of developing an economically viable strategy.The work herein takes a close look at the hazards in North Sea offshore seismic surveying,in order to identify critical risk factors,leading to marine seismic survey accidents.The risk factors leading to undesirable events are analysed both qualitatively and quantitatively.A risk matrix is introduced to screen the identified undesirable events.Further to the screening,Fault Tree Analysis(FTA)is presented to investigate and analyse the most critical risks of seismic survey operation,taking into account the lack of historical data.The obtained results show that man overboard(MOB)event is a major risk factor in marine seismic survey operation;lack of training on safe work practice,slippery deck as a result of rain,snow or water splash,sea state affecting human judgement,and poor communication are identified as the critical risk contributors to the MOB event.Consequently,the risk control options are focused on the critical risk contributors for decision-making.Lastly,suggestions for the introduction and development of the FSA methodology are highlighted for safer marine and offshore operations in general.Gregory Asuelimen Eduardo Blanco-Davis Jin Wang Zaili Yang Dante Benjamin Matellini 2020Journal of Marine Science and Application2020,19,2:2

14Celastrol enhances transcription factor EB (TFEB)-mediated autophagy and mitigates Tau pathology:Implications for Alzheimer's disease therapy显示文摘Alzheimer's disease(AD),characterized by the accumulation of protein aggregates including phosphorylated Tau aggregates,is the most common neurodegenerative disorder with limited therapeutic agents.Autophagy plays a critical role in the degradation of phosphorylated Tau aggregates,and transcription factor EB(TFEB)is a master regulator of autophagy and lysosomal biogenesis.Thus,small-molecule autophagy enhancers targeting TFEB hold promise for AD therapy.Here,we found that celastrol,an active ingredient isolated from the root extracts of Tripterygium wilfordii(Lei Gong Teng in Chinese)enhanced TFEB-mediated autophagy and lysosomal biogenesis in vitro and in mouse brains.Importantly,celastrol reduced phosphorylated Tau aggregates and attenuated memory dysfunction and cognitive deficits in P301S Tau and 3xTg mice,two commonly used AD animal models.Mechanistical studies suggest that TFEB-mediated autophagy-lysosomal pathway is responsible for phosphorylated Tau degradation in response to celastrol.Overall,our findings indicate that Celastrol is a novel TFEB activator that promotes the degradation of phosphorylated Tau aggregates and improves memory in AD animal models.Therefore,Celastrol shows potential as a novel agent for the treatment and/or prevention of AD and other tauopathies.Chuanbin Yang Chengfu Su Ashok Iyaswamy Senthil Kumar Krishnamoorthi Zhou Zhu Sichang Yang Benjamin Chunkit Tong Jia Liu Sravan G.Sreenivasmurthy Xinjie Guan Yuxuan Kan Aston Jiaxi Wu Alexis Shiying Huang Jieqiong Tan Kingho Cheung Juxian Song Min Li 2022Acta Pharmaceutica Sinica B2022,12,4:2

19Wind-induced instabilities and monitoring of wind turbine显示文摘This paper presents real-time monitoring data and analysis results of the non-stationary vibrations of an operational wind turbine. The advanced time-frequency spectrum analysis reveals varied non-stationary vibrations with timevarying frequencies, which are correlated with certain system natural modes characterized by finite element analysis. Under the effects of strong wind load, the wind turbine system exhibits certain resonances due to blade passing excitations. The system also exhibits certain instabilities due to the coupling of the tower bending modes and blade flapwise mode with blade passing excitations under the variation of wind speed. An analytical model is used to elaborate the non-stationary and instability phenomena observed in experimental results. The properties of the nonlinear instabilities are evaluated by using Lyapunov exponent estimation.Isaac Wait Zhaohui (Joey) Yang Gang Chen Benjamin Still 2019Earthquake Engineering and Engineering Vibration2019,18,2:1
