| 1 | Overview of multiplex immunohistochemistry/immunofluorescence techniques in the era of cancer immunotherapy显示文摘Conventional immunohistochemistry(IHC)is a widely used diagnostic technique in tissue pathology.However,this technique is associated with a number of limitations,including high inter-observer variability and the capacity to label only one marker per tissue section.This review details various highly multiplexed techniques that have emerged to circumvent these constraints,allowing simultaneous detection of multiple markers on a single tissue section and the comprehensive study of cell composition,cellular functional and cell-cell interactions.Among these techniques,multiplex Immunohistochemistry/Immunofluorescence(mIHC/IF)has emerged to be particularly promising.mIHC/IF provides high-throughput multiplex staining and standardized quantitative analysis for highly reproducible,efficient and cost-effective tissue studies.This technique has immediate potential for translational research and clinical practice,particularly in the era of cancer immunotherapy. | Wei Chang Colin Tan Sanjna Nilesh Nerurkar Hai Yun Cai Harry Ho Man Ng Duoduo Wu Yu Ting Felicia Wee Jeffrey Chun Tatt Lim Joe Yeong Tony Kiat Hon Lim | 2020 | Cancer Communications2020，40，4： | 11 |
| 2 | Highly efficient S_(2-)-adsorbed MoSx-modified TiO_(2) photocatalysts:A general grafting strategy and boosted interfacial charge transfer显示文摘Exploiting efficient and low-cost cocatalyst with a facile grafting strategy is of critical importance for significantly boosting the photocatalytic H2-evolution activity.In this study,S2^--adsorbed MoSx nanoparticle as a superior H2-evolutoin cocatalyst was successfully grafted on the TiO2 surface to greatly boost its photocatalytic activity via one-step lactic acid-induced synthesis strategy.Herein,the lactic acid can induce the homogeneous production of amorphous MoSx(a-MoSx)nanoparticles from MoS42-precursor,while the symbiotic S2^-ions can be easily and availably self-adsorbed on the a-Mo Sxsurface,resulting in the formation of S2^--adsorbed a-Mo Sxnanoparticles with a small size of 0.5-3 nm.Photocatalytic results manifested that the S2^--adsorbed Mo Sxnanoparticles could dramatically facilitate the H2-generation rate of TiO2 photocatalysts(3452μmol h^-1 g^-1,AQE=16.5%).In situ irradiated XPS in conjunction with transient-state PL and photoelectrochemical tests reveal that the improved H_(2)-generation activity can be ascribed to the synergistic effect of boosted interfacial charge transfer from TiO_(2) to S^(2-)adsorbed Mo Sx and the superior H_(2)-evolution reaction on self-adsorbed S_(2-)ions.In addition,the S^(2-)-adsorbed Mo Sx nanoparticles can also act as the general H_(2)-generation cocatalyst to obviously promote the activity of other typical host photocatalysts such as g-C_(3) N_(4) and Cd S.This work provides an innovative approach to develop high-efficiency Mo Sx-based cocatalyst with boosted interfacial charge transfer toward highly efficient photocatalytic materials. | Duoduo Gao Ranran Yuan Jiajie Fan Xuekun Hong Huogen Yu | 2020 | Journal of Materials Science & Technology2020，56，21： | 3 |
| 3 | 肿瘤免疫治疗时代的多重免疫组织化学/免疫荧光技术显示文摘常规免疫组织化学(immunohistochemistry,IHC)是组织病理学中广泛应用的诊断技术。但该技术存在诸多局限性,包括观察者间的变异性高,每张组织切片仅能标记一个标志物。本文详细描述了各种多重检测技术,这些技术克服了上述局限性,可在单张切片上同时检测多个标志物,可对细胞组成、细胞功能和细胞间相互作用进行整合研究。在这些技术中,多重免疫组织化学/免疫荧光(multiplex immunohistochemistry/immunofluorescence,mIHC/IF)已成为最具应用前景的技术。mIHC/IF为开展高重复性、高效、高性价比的组织研究提供了高通量多重染色技术和标准化的定量分析。该技术在转化研究和临床实践中,尤其是肿瘤免疫治疗中极具应用价值。 | Wei Chang Colin Tan Sanjna Nilesh Nerurkar Hai Yun Cai Harry Ho Man Ng Duoduo Wu Yu Ting Felicia Wee Jeffrey Chun Tatt Lim Joe Yeong Tony Kiat Hon Lim | 2021 | 癌症2021，40，9： | 2 |
| 4 | Texture evolution and slip mode of a Ti-5.5Mo-7.2Al-4.5Zr-2.6Sn-2.1Cr dual-phase alloy during cold rolling based on multiscale crystal plasticity finite element model显示文摘The complex micromechanical response among grains remains a persistent challenge to understand the deformation mechanism of titanium alloys during cold rolling.Therefore,in this work,a multiscale crystal plasticity finite element method of dual-phase alloy was proposed and secondarily developed based on LS-DYNA software.Afterward,the texture evolution and slip mode of a Ti-5.5Mo-7.2Al-4.5Zr-2.6Sn-2.1Cr alloy,based on the realistic 3D microstructure,during cold rolling(20%thickness reduction)were systematically investigated.The relative activity of the■slip system in theαphase gradually increased,and then served as the main slip mode at lower Schmid factor(<0.2).In contrast,the contribution of the■slip system to the overall plastic deformation was relatively limited.For theβphase,the relative activity of the<111>{110}slip system showed an upward tendency,indicating the important role of the critical resolved shear stress relationship in the relative activity evolutions.Furthermore,the abnormally high strain of very fewβgrains was found,which was attributed to their severe rotations compelled by the neighboring pre-deformedαgrains.The calculated pole figures,rotation axes,and compelled rotation behavior exhibited good agreement to the experimental results. | Duoduo Wang Qunbo Fan Xingwang Cheng Yu Zhou Ran Shi Yan Qian Le Wang Xinjie Zhu Haichao Gong Kai Chen Jingjiu Yuan Liu Yang | 2022 | Journal of Materials Science & Technology2022，，16： | 2 |
| 5 | Multi-scale crystal plasticity finite element simulations of the microstructural evolution and formation mechanism of adiabatic shear bands in dual-phase Ti20C alloy under complex dynamic loading显示文摘A dynamic compression test was performed on α+β dual-phase titanium alloy Ti20C using a split Hopkinson pressure bar.The formation of adiabatic shear bands generated during the compression process was studied by combining the proposed multi-scale crystal plasticity finite element method with experimental measurements.The complex local micro region load was progressively extracted from the simulation results of a macro model and applied to an established three-dimensional multi-grain microstructure model.Subsequently,the evolution histories of the grain shape,size,and orientation inside the adiabatic shear band were quantitatively simulated.The results corresponded closely to the experimental results obtained via transmission electron microscopy and precession electron diffraction.Furthermore,by calculating the grain rotation and temperature rise inside the adiabatic shear band,the microstructural softening and thermal softening effects of typical heavily-deformed α grains were successfully decoupled.The results revealed that the microstructural softening stress was triggered and then stabilized(in general)at a relatively high value.This indicated that the mechanical strength was lowered mainly by the grain orientation evolution or dynamic recrystallization occurring during early plastic deformation.Subsequently,thermal softening increased linearly and became the main softening mechanism.Noticeably,in the final stage,the thermal softening stress accounted for 78.4% of the total softening stress due to the sharp temperature increase,which inevitably leads to the stress collapse and potential failure of the alloy. | Yu Zhou Qunbo Fan Xin Liu Duoduo Wang Xinjie Zhu Kai Chen | 2020 | Journal of Materials Science & Technology2020，59，24： | 1 |
| 6 | Optimal exercise intensity and volume to impact rats with Traditional Chinese Medicine phlegm-dampness constitution显示文摘Objective:We aim to investigate the effects of different exercise intensities and volumes on Phlegm-dampness constitution(PDC).Methods:The rats were fed with high-fat food and lived in 75%–85%humidity for 6 weeks to establish the model of PDC.Then PDC rats were screened and intervened by varying exercise intensities for 8 weeks.Weight,constitution scores,blood and liver tissues were collected to detect the concentration of serum total cholesterol(Tch),triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),homocysteine(Hcy),blood glucose(GLU),alanine transaminase(ALT)and percentage of lipid droplet area in liver tissue(PLDA).Results:The weight,Tch,TG,HDL-C,LDL-C,Hcy,GLU,and ALT of rats in moderate-intensity exercise group returned to normal.The rats with high-intensity or low-intensity exercise did not recover as well as moderate-intensity.Conclusion:Different exercise intensities and volumes have different effects on PDC,moderate-intensity exercise over an 8-week intervention is most appropriate. | Zhangmeng Xu Yong Chen Duoduo Yu Donghong Feng Chenjian Tang Tao Li Jing Zhou Yaming Yu | 2021 | Sports Medicine and Health Science2021，3，1： | 1 |
| 7 | New genetic and epigenetic insights into the chemokine system: the latest discoveries aiding progression toward precision medicine显示文摘Over the past thirty years,the importance of chemokines and their seven-transmembrane G protein-coupled receptors(GPCRs)has been increasingly recognized.Chemokine interactions with receptors trigger signaling pathway activity to form a network fundamental to diverse immune processes,including host homeostasis and responses to disease.Genetic and nongenetic regulation of both the expression and structure of chemokines and receptors conveys chemokine functional heterogeneity.Imbalances and defects in the system contribute to the pathogenesis of a variety of diseases,including cancer,immune and inflammatory diseases,and metabolic and neurological disorders,which render the system a focus of studies aiming to discover therapies and important biomarkers.The integrated view of chemokine biology underpinning divergence and plasticity has provided insights into immune dysfunction in disease states,including,among others,coronavirus disease 2019(COVID-19).In this review,by reporting the latest advances in chemokine biology and results fromanalyses of a plethora of sequencing-based datasets,we outline recent advances in the understanding of the genetic variations and nongenetic heterogeneity of chemokines and receptors and provide an updated view of their contribution to the pathophysiological network,focusing on chemokine-mediated inflammation and cancer.Clarification of the molecular basis of dynamic chemokine-receptor interactions will help advance the understanding of chemokine biology to achieve precision medicine application in the clinic. | Hanli Xu Shuye Lin Ziyun Zhou Duoduo Li Xiting Zhang Muhan Yu Ruoyi Zhao Yiheng Wang Junru Qian Xinyi Li Bohan Li Chuhan Wei Keqiang Chen Teizo Yoshimura Ji Ming Wang Jiaqiang Huang | 2023 | Cellular & Molecular Immunology2023，20，7： | 0 |

| 9 | Ganoderma atrum polysaccharide relieves mitochondrial dysfunction to alleviate hydrogen peroxide-induced senescence via activating autophagy显示文摘Polysaccharides from genus Ganoderma have prominent anti-aging effect,but their mechanisms are incompletely clarified.In our previous experiments,Ganoderma atrum polysaccharide(PSG)was exhibited to significantly alleviate senescence and DNA damage of A375 cells.To investigate its underlying mechanism,we conducted RNA-Seq analysis and found that PSG upregulated autophagy and mitochondria pathways compared to the model group.Further experiments showed that PSG relieved mitochondrial dysfunction via inhibiting the accumulation of reactive oxygen species(ROS)and loss of the mitochondrial membrane potential(MMP).Meanwhile,PSG activated autophagy and enhanced lysosomal function through transcription factor EB(TFEB).Interestingly,the pretreatment of autophagy inhibitors bafilomycin A1(Baf A1)reversed the ROS decline induced by PSG,which subsequently increased cellular senescence of A375.In addition,PSG had a similar anti-aging effect on normal fibroblast WI-38.Taken together,PSG might reduce ROS levels through activating autophagy,which in turn suppressed mitochondrial dysfunction and cellular senescence. | Mi Guo Ke Zhang Duoduo Zhang Yujia Zhou Linyuan Liu Yu Wu Xingtao Zhou Shaoping Nie | 2022 | Journal of Future Foods2022，2，3： | 0 |
