3Neuroprotectants attenuate hypobaric hypoxia-induced brain injuries in cynomolgus monkeys显示文摘Hypobaric hypoxia (HH) exposure can cause serious brain injury as well as life-threatening cerebral edema in severe cases. Previous studies on the mechanisms of HH-induced brain injury have been conducted primarily using non-primate animal models that are genetically distant to humans, thus hindering the development of disease treatment. Here, we report that cynomolgus monkeys (Macaca fascicularis) exposed to acute HH developed human-like HH syndrome involving severe brain injury and abnormal behavior. Transcriptome profiling of white blood cells and brain tissue from monkeys exposed to increasing altitude revealed the central role of the HIF-1 and other novel signaling pathways, such as the vitamin D receptor (VDR) signaling pathway, in co-regulating HH-induced inflammation processes. We also observed profound transcriptomic alterations in brains after exposure to acute HH, including the activation of angiogenesis and impairment of aerobic respiration and protein folding processes, which likely underlie the pathological effects of HH-induced brain injury. Administration of progesterone (PROG) and steroid neuroprotectant 5α-androst-3β,5,6β-triol (TRIOL) significantly attenuated brain injuries and rescued the transcriptomic changes induced by acute HH. Functional investigation of the affected genes suggested that these two neuroprotectants protect the brain by targeting different pathways, with PROG enhancing erythropoiesis and TRIOL suppressing glutamate-induced excitotoxicity. Thus, this study advances our understanding of the pathology induced by acute HH and provides potential compounds for the development of neuroprotectant drugs for therapeutic treatment.Pei Zhang Jie-Si Chen Qi-Ye Li Long-Xiang Sheng Yi-Xing Gao Bing-Zheng Lu Wen-Bo Zhu Xiao-Yu Zhan Yuan Li Zhi-Bing Yuan Gang Xu Bi-Tao Qiu Min Yan Chun-Xue Guo You-Qiong Wang Yi-Jun Huang Jing-Xia Zhang Fu-Yu Liu Zhong-Wei Tang Sui-Zhen Lin David NCooper Huan-Ming Yang Jian Wang Yu-Qi Gao Wei Yin Guo-Jie Zhang Guang-Mei Yan 2020Zoological Research2020,41,1:6

6COMPARING PERFORMANCE OF CROP SPECIES MIXTURES AND PURE STANDS显示文摘Intercropping is the planned cultivation of species mixtures on agricultural land.Intercropping has many attributes that make it attractive for developing a more sustainable agriculture,such as high yield,high resource use efficiency,lower input requirements,natural suppression of pests,pathogens and weeds,and building a soil with more organic carbon and nitrogen.Information is needed which species combinations perform best under different circumstances and which management is suitable to bring out the best from intercropping in a given production situation.The literature is replete with case studies on intercropping from across the globe,but evidence synthesis is needed to make this information accessible.Meta-analysis requires a careful choice of metric that is appropriate for answering the question at hand,and which lends itself for a robust meta-analysis.This paper reviews some metrics that may be used in the quantitative synthesis of literature data on intercropping.Wopke VAN DER WERF Lizhen ZHANG Chunjie LI Ping CHEN Chen FENG Zhan XU Chaochun ZHANG Chunfeng GU Lammert BASTIAANS David MAKOWSKI TjeerdJan STOMPH 2021Frontiers of Agricultural Science and Engineering2021,8,3:2

9城市固体废弃物填埋场沉降机理(英文)显示文摘目的:帮助填埋场工程方面的学者和工程师更全面地了解城市固体废弃物的沉降机理。创新点:揭示填埋场城市固体废弃物的沉降机理,明确沉降计算模型的参数确定方法和不确定因素。结论:1.填埋场城市固体废弃物的沉降机理不同于传统土体,这主要是固相颗粒的可压缩性、可降解性以及孔隙流体的可压缩性不同导致的。2.可以将沉降划分为瞬时压缩、主压缩、蠕变次压缩和降解次压缩,并分别进行计算;这些计算模型虽然带有经验性,但具有很好的实用性。3.能更好反映沉降机理的模型需要耦合填埋场城市固体废弃物的降解、压缩和液气运移。4.这些耦合模型能分析更复杂的工况,但其模型参数的确定更具挑战性。William POWRIE Xiao-bing XU David RICHARDS Liang-tong ZHAN Yun-min CHEN 2019Journal of Zhejiang University-Science A(Applied Physics & Engineering)2019,20,12:2

20Is the hardness of material harder than diamond reliable?显示文摘With the development of new synthesis methods and chemistries,a number of new superhard materials have been reported to be harder than diamond.While such materials are highly desirable due to their wide-ranging applications,there are some inherent uncertainties in the methods utilized to determine and define the hardness of such materials.In this paper,we employed the standard Vickers diamond indenter and substitute indenters with the same shape to measure the hardness of nine ceramics and superhard materials within well-defined criteria and methodology,for the assessment of consistency in the hardness testing.The findings and the developed testing method in the current study have broad implications in characterizing new and emerging superhard materials,leading to new discoveries.Jin Liu Yongtao Zou Guodong David Zhan Pei Wang Xiaozhi Yan Duanwei He Liping Wang 2023Journal of Materials Science & Technology2023,,13:0
