4Effects of adding bulking agents on the biodrying of kitchen waste and the odor emissions produced显示文摘The effects of adding a bulking agent on the performance and odor emissions(ammonia and eight sulfur-containing odorous compounds) when biodrying kitchen waste were investigated. Three treatments were considered: the addition of either cornstalks(CS) or wood peat(WP) to kitchen waste as a bulking agent before biodrying, and a control treatment(CK). The water-removal rates for CK, CS, and WP treatments were 0.35, 0.56, and0.43 kg/kg, respectively. Addition of bulking agents to kitchen waste produced less leachate,higher moisture-removal rates, and lower consumption of volatile solids. The CS treatment had the highest biodrying index(4.07), and those for the WP and CK treatments were 3.67 and 1.97, respectively. Adding cornstalks or wood peat decreased NH3 emissions by 55.8%and 71.7%, respectively. Total sulfur losses were 3.6%–21.6% after 21 days biodrying, and H2 S and Me2 SS were the main(> 95%) sulfur compounds released. The smallest amounts of sulfur-containing odorous compounds were emitted when cornstalks were added, and adding cornstalks and wood peat decreased total sulfur losses by 50.6%–64.8%.Jing Yuan Yun Li Hongyu Zhang Difang Zhang David Chadwick Guoxue Li Guoying Wang Menghao Chi Fan Yang 2018Journal of Environmental Sciences2018,30,5:7

6MicroRNA-29a attenuates angiotensin-Ⅱ induced-left ventricular remodeling by inhibiting collagen,TGF-β and SMAD2/3 expression显示文摘Background Left ventricular(LV)remodeling is the most common target organ damage in hypertension.Previously,our study found that plasma microRNA-29a(miR-29a)level was associated with the LV remodeling in hypertensive patients.However,the causal relationship between miR-29a and LV remodeling remains unknown.Thus,the aim of this study was to investigate the regulation mechanism of miR-29a in LV remodeling.Methods&Results Overexpression and knockdown miR-29a mice were generated by tail-intravenous injection of miR-29a-mimic and inhibitor lentivirus for one week respectively.Then the mice were subjected to angiotensin-II(AngII)induced LV remodeling by subcutaneous AngII capsule osmotic pumping into AngII for four weeks.AngII-induced LV remodeling mice as the model group(n=9).Age-matched male SPF C57/BL6J mice(6–8 weeks old)were treated with the pumping of saline as a vehicle(n=6).In vivo,overexpression miR-29a ameliorated AngII-induced LV remodeling,while knockdown miR-29a deteriorated LV remodeling.Simultaneously,we observed that overexpression miR-29a mice inhibited but knockdown miR-29a mice increased cardiac cross-sectional area,indicating that miR-29a has an antagonistic effect on cardiac hypertrophy.Further studies found that overexpression miR-29a inhibited the content of the LV collagen including collagen I and III.Moreover,the expression of transforming growth factor-β(TGF-β)and phosphorylated SMAD2/3 decreased with the down-regulation of collagen I and III in overexpression miR-29a mice.Conclusions Our finding indicates that overexpression miR-29a attenuates LV remodeling by inhibiting collagen deposition,TGF-β,and phosphorylated SMAD2/3 expression.Thus,intervention miR-29a may be a therapeutic target for attenuating LV remodeling.Si-Jin ZHANG Cui-Juan YUN Jie LIU Si-Yu YAO Yao LI Miao WANG Chi WANG Yong-Yi BAI Hao XUE 2020Journal of Geriatric Cardiology2020,17,2:7

9Establishing a nonlethal and efficient mouse model of male gonadotoxicity by intraperitoneal busulfan injection显示文摘An ideal animal model of azoospermia would be a powerful tool for the evaluation of spermatogonial stem cell(SSC)transplantation.Busulfan has been commonly used to develop such a model,but 30%–87%of mice die when administered an intraperitoneal injection of 40 mg kg^?1.In the present study,hematoxylin and eosin staining,Western blot,immunofluorescence,and quantitative real-time polymerase chain reaction were used to test the effects of busulfan exposure in a mouse model that received two intraperitoneal injections of busulfan at a 3-h interval at different doses(20,30,and 40 mg kg^?1)on day 36 or a dose of 40 mg kg^?1 at different time points(0,9,18,27,36,and 63 days).The survival rate of the mice was 100%.When the mice were treated with 40 mg kg^?1 busulfan,dramatic SSC depletion occurred 18 days later and all of the germ cells were cleared by day 36.In addition,the gene expressions of glial cell line-derived neurotrophic factor(GDNF),fibroblast growth factor 2(FGF2),chemokine(C-X-C Motif)ligand 12(CXCL12),and colony-stimulating factor 1(CSF1)were moderately increased by day 36.A 63-day,long-term observation showed the rare restoration of endogenous germ cells in the testes,suggesting that the potential period for SSC transplantation was between day 36 and day 63.Our results demonstrate that the administration of two intraperitoneal injections of busulfan(40 mg kg^?1 in total)at a 3-h interval to mice provided a nonlethal and efficient method for recipient preparation in SSC transplantation and could improve treatments for infertility and the understanding of chemotherapy-induced gonadotoxicity.Yun Xie Cun-Can Deng Bin Ouyang Lin-Yan Lv Jia-Hui Yao Chi Zhang Hai-Cheng Chen Xiao-Yan Liang Xiang-Zhou Sun Chun-Hua Deng Gui-Hua Liu 2020Asian Journal of Andrology2020,22,2:5
10Exposure Effects of Terahertz Waves on Primary Neurons and Neuron-like Cells Under Nonthermal Conditions显示文摘Objective This study aimed to explore the potential effects of terahertz(THz) waves on primary cultured neurons from 4 rat brain regions(hippocampus, cerebral cortex, cerebellum, and brainstem)and 3 kinds of neuron-like cells(MN9 D, PC12, and HT22 cells) under nonthermal conditions.Methods THz waves with an output power of 50(0.16 THz) and 10(0.17 THz) m W with exposure times of 6 and 60 min were used in this study. Analysis of temperature change, neurite growth, cell membrane roughness, micromorphology, neurotransmitters and synaptic-related proteins(SYN and PSD95) was used to evaluate the potential effects.Results Temperature increase caused by the THz wave was negligible. THz waves induced significant neurotransmitter changes in primary hippocampal, cerebellar, and brainstem neurons and in MN9 D and PC12 cells. THz wave downregulated SYN expression in primary hippocampal neurons and downregulated PSD95 expression in primary cortical neurons.Conclusion Different types of cells responded differently after THz wave exposure, and primary hippocampal and cortical neurons and MN9 D cells were relatively sensitive to the THz waves. The biological effects were positively correlated with the exposure time of the THz waves.TAN Sheng Zhi TAN Peng Cheng LUO Lan Qing CHI Yun Liang YANG Zi Long ZHAO Xue Long ZHAO Li DONG Ji ZHANG Jing YAO Bin Wei XU Xin Ping TIAN Guang CHEN Jian Kui WANG Hui PENG Rui Yun 2019Biomedical and Environmental Sciences2019,32,10:5

14Phase-field simulation of solidification dendritic segregation in Ti-45Al alloy显示文摘The microstructures and mechanical properties of Ti Al alloys are directly linked to micro-segregation which cannot be avoided during solidification. So a thorough understanding of the micro-segregation should be a great help to further enhance the mechanical properties of the cast products. Theoretical analysis and experiments have been used to predict the micro-segregation, but it is very difficult to observe and determine the dendritic segregation in the micro region. Phase-field method has been employed for the simulation of dendritic growth. However, due to the complicated quasi-sub regular solution model for Ti-45Al(at.%) alloy, the classic phase-field models have difficulty to deal with the free energy. In this work, a phase-field model by linking thermodynamic calculation was used to simulate solidification dendritic segregation of Ti-45 Al alloy for Liquid→Liquid+β(Ti). The free energies of solid phase and liquid phase for Ti-45 Al alloy were calculated by Thermo-Calc and then coupled with the phase-field equations. The simulation results show the dendritic morphology and Al content variations between liquid and growing solid phase for Ti-45 Al alloy. With the growth of the β(Ti), dendritic segregation is formed in the liquid and solid phases due to the solute partitioning and rejection into the liquid. As a result, the dendrite arms are depleted of Al element, while the inter-dendrites are enriched. The dendritic tip growth velocity decreases with the progress of solidification, whereas the segregation ratio increases.Yu-tuo Zhang Yun Chi Chun-qing Hu 2017China Foundry2017,14,3:3
15Current status and future applications of contrast-enhanced endoscopic ultrasonography显示文摘Endoscopic ultrasonography(EUS) is currently an in-tegral investigation of many gastrointestinal disorders.It has been shown to have a higher efficacy thanconventional computed tomography in detection andcharacterization of small lesions especially in the pan-creas. Much effort has been put to further improvethe sensitivity, specificity and overall accuracy of EUS.One of the major advances is the utilization of contrastagents for better delineation of the vascularity and tis-sue perfusion of the target lesion. This article describesthe basic principles of ultrasound contrast agents andthe different modalities used in contrast-enhanced EUS(CE-EUS) including contrast-enhanced Doppler EUS(CED-EUS) and contrast-enhanced harmonic EUS(CEH-EUS). In addition, the current applications of contrastenhanced EUS in different gastrointestinal conditionswere discussed. Furthermore, the future developmentof hybrid approaches combining CE-EUS with other im-aging modalities and the potential therapeutic aspectof using it as a vector for drug delivery were also dis-cussed.Hon Chi Yip Anthony Yuen Bun Teoh Charing Ching Ning Chong James Yun Wong Lau 2014World Journal of Gastrointestinal Endoscopy2014,6,4:3
16Effects of Cerium on Microstructures and Mechanical Properties of Zn-22%Al Vibration Damping Alloy显示文摘Using natural aging and artificial aging treatment, the effects of cerium on microstructures and mechanical properties of Zn 22%Al vibration damping alloy were studied by optical microscope, transmission electron microscope and scanning electron microscope. The results show that cerium can refine the microstructure of Zn 22%Al alloy, slow the grain growth and retain the equiaxial degree during aging. The strength of Zn 22%Al (0 07%~0 20%)Ce alloy and Zn 22%Al alloy remains constant after aging below the hot rolling temperature of 80 ℃, and cerium can improve the strength and the stability of mechanical properties of Zn 22%Al alloy.PANG Shao ping, SHI Yun bao, LI Jun, YANG Bin jiu, QUAN Mei hua, QIAO Yan hui, ZHANG Chi zhong (College of Mechanical Engineering, Beihua University, Jilin 132021, China) 2000Journal of Rare Earths2000,18,4:3

20A novel spoof surface plasmon polariton structure to reach ultra-strong field confinements显示文摘Ultrathin corrugated metallic structures have been proved to support spoof surface plasmon polariton (SPP) modes on two-dimension (2D) planar microwave circuits.However,to provide stronger field confinement,larger width of strip is required to load deeper grooves,which is cumbersome in modern large-scale integrated circuits and chips.In this work,a new spoof SPP transmission line (TL) with zigzag grooves is proposed.This new structure can achieve stronger field confinement compared to conventional one with the same strip width.In other words,the proposed spoof SPP TL behaves equivalently to a conventional one with much larger size.Dispersion analysis theoretically indicates the negative correlation between the ability of field confinement and cutoff frequencies of spoof SPP TLs.Numerical simulations indicate that the cutoff frequency of the proposed TL is lower than the conventional one and can be easily modified with the fixed size.Furthermore,two samples of the new and conventional spoof SPP TLs are fabricated for experimental demonstration.Measured S-parameters and field distributions verify the ultra-strong ability of field confinement of the proposed spoof SPP TL.Hence,this novel spoof SPP structure with ultra-strong field confinement may find wide applications in microwave and terahertz engineering.Pei Hang He Hao Chi Zhang Xinxin Gao Ling Yun Niu Wen Xuan Tang Jiayuan Lu Le Peng Zhang Tie Jun Cui 2019Opto-Electronic Advances2019,2,6:2
