| 1 | Recycling combustibles from aged municipal solid wastes(MSW)to improve fresh MSW incineration in Shanghai:Investigation of necessity and feasibility显示文摘Aged municipal solid wastes(MSW)excavated from landfills and dumpsites were characterized to analyze their fraction composition,moisture content,and lower heat value(LHV).The necessity and feasibility of recycling combustibles from aged MSW to improve the incineration of fresh MSW were investigated.The results showed that combustibles in aged MSW were easily separated from other components and than LHV of the separated combustibles are higher than 11000 kJ/kg.The fresh MSW are of high moisture contents with average LHV below 6500 kJ/kg,making their stable combustion difficult to maintain in MSW incinerators.For both fresh MSW and aged MSW,plastics are the main contributor to their LHV.To improve incineration of fresh MSW that are characterized with low LHV,combustibles separated from aged MSW were made into refuse derived fuel(RDF)pellets and were then added to fresh MSW by 2%wt.–5%wt.LHV variation and air supply resistance change of the MSW layer on the incinerator grate caused by the addition of RDF was checked,and no significant changes were found.No obvious difference was observed for the‘burn-out time’between RDF pellets and fresh MSW either.RDF made from aged MSW combustibles is found to be a promising auxiliary fuel to improve the incineration of fresh MSW,and aged MSW from old landfill cells and dumpsites can be finally disposed of jointly with fresh MSW by recycling combustible from the former to be coincinerated with the latter in the incineration plants. | Dezhen CHEN Zhenzhen GUAN Guangyu LIU Gongming ZHOU Tong ZHU | 2010 | Frontiers of Environmental Science & Engineering2010，4，2： | 1 |
| 2 | Undescribed Meroterpenoids from Hypericum japonicum with Neuroprotective Effects on H_(2)O_(2) Insult SH-SY5Y Cells Targeting Keap1-Nrf2显示文摘Unreported tautomeric/enantiomeric meroterpenoids,(±)-hyperjaponols I—K(1-3),were discovered from Hypericum japonicum.Comprehensive chemical investigations established the absolute characteristics of these stereoisomers.The TS calculation demon-strated that 1a and 2a easily occur enol-keto tautomerism with steady configurations individually.Amongst isolates,1b showed the strongest neuroprotective activity with the concentration at 25μmol/L on H_(2)O_(2) insult SH-SY5Y cells.In vitro molecular biological ex-periments manifested that 1b activated the Keap1-Nrf2-ARE pathway,leading to the promotion of Nrf2 nuclear translocation,down-regulation of the expression level of Keap1,and upregulation of the levels of Nrf2,NQO-1,and HO-1.The results of in silico simulation showed that 1b possessed good binding features with Keap1(5FNQ)via forming multiple typical hydrogen and hydrophobic bonds as well as less fluctuation of RMSD and RMSF during a natural physiological condition. | Linzhen Hu Zhenzhen Wang Zhou Tong Ping Hu Luqi Kong Mengying Luo Xiao-Nian Li Yuexing Zhang Zhiyong Huang Yonghui zhang | 2022 | Chinese Journal of Chemistry2022，40，11： | 1 |
| 3 | Fracture analysis of magnetoelectroelastic bimaterials with imperfect interfaces by symplectic expansion显示文摘A Hamiltonian-based analytical method is used to study the mode Ⅲ interface cracks in magnetoelectroelastic bimaterials with an imperfect interface. By introducing an unknown vector, the governing equations are reformulated in sets of first-order ordinary differential equations. Using separation of variables, eigensolutions in the symplectic space are obtained. An exact solution of the unknown vector is obtained and expressed in terms of symplectic eigensolutions. Singularities of mechanical, electric, and magnetic fields are evaluated with the generalized intensity factors. Comparisons are made to verify accuracy and stability of the proposed method. Numerical examples including mixed boundary conditions are given. | Xinsheng XU Zhenzhen TONG Dalun RONG Xianhe CHENG Chenghui XU Zhenhuan ZHOU | 2017 | Applied Mathematics and Mechanics(English Edition)2017，38，8： | 0 |
| 4 | Characteristics of patients with chronic airflow obstruction caused by solid fuel or tobacco smoke显示文摘To the Editor: Chronic airflow obstruction (CAO) is a characteristic feature of chronic obstructive pulmonary disease (COPD) and occurs due to airway and/or alveolar abnormalities typically associated with exposure to noxious particles or gases.[1] The major risk factor for CAO is cigarette smoking, but exposure to solid fuel likely influences CAO development. Studies have found that solid fuel exposure is associated with a high prevalence of CAO, particularly among women.[2] Comparing COPD caused by either solid fuel or tobacco smoke exposure is very significant because about 3 billion people are exposed to solid fuel smoke, and 1.01 billion people smoke tobacco, globally. This study aimed to investigate and compare the clinical and functional characteristics of CAO patients exposed to solid fuel and tobacco smoke using propensity score matching (PSM) in western China. | Huanyu Long Zhenzhen Xing Di Chai Weiming Liu Yaqi Tong Yuxia Wang Yali Ma Mingming Pan Jia Cui Yanfei Guo | 2022 | Chinese Medical Journal2022，，5： | 0 |
| 5 | The first chromosome-level Fallopia multiflora genome assembly provides insights into stilbene biosynthesis显示文摘Fallopia multiflora(Thunb.)Harald,a vine belonging to the Polygonaceae family,is used in traditional medicine.The stilbenes contained in it have significant pharmacological activities in anti-oxidation and anti-aging.This study describes the assembly of the F.multiflora genome and presents its chromosome-level genome sequence containing 1.46 gigabases of data(with a contig N50 of 1.97 megabases),1.44 gigabases of which was assigned to 11 pseudochromosomes.Comparative genomics confirmed that F.multiflora shared a whole-genome duplication event with Tartary buckwheat and then underwent different transposon evolution after separation.Combining genomics,transcriptomics,and metabolomics data to map a network of associated genes and metabolites,we identified two FmRS genes responsible for the catalysis of one molecule of p-coumaroyl-CoA and three molecules of malonyl-CoA to resveratrol in F.multiflora.These findings not only serve as the basis for revealing the stilbene biosynthetic pathway but will also contribute to the development of tools for increasing the production of bioactive stilbenes through molecular breeding in plants or metabolic engineering in microbes.Moreover,the reference genome of F.multiflora is a useful addition to the genomes of the Polygonaceae family. | Yujiao Zhao Zhengyang Yang Zhongren Zhang Minzhen Yin Shanshan Chu Zhenzhen Tong Yuejian Qin Liangping Zha Qingying Fang Yuan Yuan Luqi Huang Huasheng Peng | 2023 | Horticulture Research2023，10，5： | 0 |

| 7 | An Optimal Design of the Two-Staged Square Sectional Combined Energy Absorption Structure with Local Surface Nanocrystallization显示文摘In this paper,a local surface nanocrystallization technology is used for thin-walled structures with square cross sections,and an energy absorption device of two-staged combined energy absorption structure is proposed.In virtue of the surface nanocrystallization that enables to change the material on local positions,the structural deformation is induced and controlled to maximize the energy absorption capacity.A numerical model of the two-staged combined energy absorption structure is established,and the local surface nanocrystallization layout is optimized.The results show that the specific energy absorption of two-staged combined structure with local surface nanocrystallization can be increased by 34.36%compared with the untreated counterpart of the same material and structural shape.The ratio between the first and second peak crushing forces and the energy absorption allocation ratio between the two stages can be adjusted in the ranges of 0.26–0.55 and 0.31–0.45,respectively,which can be controlled by the local surface nanocrystallization designs.The numerical simulation and experimental results are in good agreement,which shows that the design for energy absorption device with local surface nanocrystallization is feasible and effective. | Xinsheng Xu Jianlong Qu Tong Li Zhenzhen Tong Zhen Zhao Zhenhuan Zhou | 2021 | Acta Mechanica Solida Sinica2021，34，6： | 0 |
| 8 | Xylanase improves the intestinal barrier function of Nile tilapia(Oreochromis niloticus)fed with soybean(Glycine max)meal显示文摘Background Soybean(Glycine max)meal is one of the important protein sources for fish,but the non-starch polysaccharides(NSP)in soybean meal impair the intestinal barrier function.Here we aimed to investigate whether xylanase can alleviate the adverse effects on the gut barrier induced by soybean meal in Nile tilapia and to explore the possible mechanism.Results Nile tilapia(Oreochromis niloticus)(4.09±0.02 g)were fed with two diets including SM(soybean meal)and SMC(soybean meal+3,000 U/kg xylanase)for 8 weeks.We characterized the effects of xylanase on the gut barrier,and the transcriptome analysis was performed to investigate the underlying mechanism.Dietary xylanase improved intestinal morphology and decreased the concentration of lipopolysaccharide(LPS)in serum.The results of transcriptome and Western blotting showed that dietary xylanase up-regulated the expression level of mucin2(MUC2)which may be related to the inhibition of protein kinase RNA-like endoplasmic reticulum kinase(perk)/activating transcription factor 4(atf4)signaling pathways.Microbiome analysis showed that addition of xylanase in soybean meal altered the intestinal microbiota composition and increased the concentration of butyric acid in the gut.Notably,dietary sodium butyrate was supplemented into the soybean meal diet to feed Nile tilapia,and the data verified that sodium butyrate mirrored the beneficial effects of xylanase.Conclusions Collectively,supplementation of xylanase in soybean meal altered the intestinal microbiota composition and increased the content of butyric acid which can repress the perk/atf4 signaling pathway and increase the expression of muc2 to enhance the gut barrier function of Nile tilapia.The present study reveals the mechanism by which xylanase improves the intestinal barrier,and it also provides a theoretical basis for the application of xylanase in aquaculture. | Tong Wang Nannan Zhou Junyi He Zhenzhen Hao Chentao Zhou Yidi Du Zhenyu Du Xiaoyun Su Meiling Zhang | 2023 | Journal of Animal Science and Biotechnology2023，14，5： | 0 |
