1叶尔羌灌区冬小麦生育期 SPAC 水热传输的模拟研究显示文摘本文应用土壤水动力学、微气象学和能量平衡原理,建立了作物生育期土壤植物大气连续体(SPAC)的水热迁移和转化模型,并采用全隐式有限差分方法进行离散,通过自动调节计算步长和反复迭代等方法设计了数值模拟程序.运用本模型对新疆叶尔羌河流域地下水均衡场1995年3月~6月冬小麦返青至成熟期的田间水热状况进行了模拟.结果证明,该模型较真实地反映了非冻结期作物生长过程中土壤中的水热状况以及地表和作物蒸散发的动态变化过程,可用于墒情预报以及农田蒸散发的研究.Mao Xiaomin Yang Shixiu Lei Zhidong (Tsinghua University) 1998水利学报1998,29,7:21
2Organic amendment effects on nematode distribution within aggregate fractions in agricultural soils显示文摘To evaluate the effect of organic amendments on soil nematode community composition and diversity within aggregate fractions,a study was initiated in agricultural soils with four-year organic amendments.Soil samples were collected from the plow layer(0-20 cm)under three cornfield management scenarios:1)conventional cropping(CK,corn straw removal and no organic manure application);2)straw retention(SR,incorporation of chopped corn stalk);and 3)manure application(MA,chicken manure input).The soil samples were fractionated into four aggregate sizes,i.e.,>2 mm(large macroaggregates),1-2 mm(macroaggregates),0.25-1 mm(small macroaggregates),and<0.25 mm(microaggregates,silt and clay fractions).The composition and diversity of soil nematode communities were determined within each aggregate fraction.The results showed that both SR and MA treatments significantly increased the percentage of macroaggregates(>1 mm)and only MA treatment strongly increased the mean weight diameter compared to the CK(P<0.05).The abundance of total nematodes and four trophic groups were affected significantly by the aggregate fractions and their higher abundance occurred in the larger aggregates.The effects of aggregate size on most nematode genera were significant.Bacterivores in the small macroaggregates and microaggregates,and fungivores in the large macroaggregates were significantly different among treatments.The percentage of bacterivores increased after the application of organic materials,while that of fungivores decreased.It can be concluded that organic management significantly affects soil aggregation and soil characteristics within aggregates,and the aggregate size subsequently influences the distribution of nematode communities.Xiaoke Zhang Xia Wu Shixiu Zhang Yuehua Xing Wenju Liang 2019Soil Ecology Letters2019,1,3:3
3Melatonin antagonizes ovarian aging via YTHDF2-MAPK-NF-κB pathway显示文摘Cellular senescence is closely associated with age-related diseases.Ovarian aging,a special type of organ senescence,is the pathophysiological foundation of the diseases of the reproductive system.It is characterized by the loss of integrity of the surface epithelium and a gradual decrease in the number of human ovarian surface epithelial cells(HOSEpiCs).To contribute to the research on delaying ovarian aging,we aimed to investigate the novel epigenetic mechanism of melatonin in protecting HOSEpiCs.We discovered that melatonin has antagonistic effects against the oncogene-induced senescence(OIS)of HOSEpiCs.Mechanistically,the oncogene Ras decreased the expression of YTHDF2,which is the reader of RNA-m6A,by stimulating the generation of reactive oxygen species(ROS).Moreover,we found that the suppression of YTHDF2 increased the expression of MAP2K4 and MAP4K4 by enhancing the stability of the transcription of their mRNAs,thereby upregulating the expression of the senescence-associated secretory phenotype(SASP)through the activation of the MAP2K4 and MAP4K4-dependent nuclear factor-κB(NF-κB)signaling pathways.We further determined that melatonin has antagonistic effects against the OIS of HOSEpiCs by inhibiting the ROS-YTHDF2-MAPK-NF-κB pathway.These findings provide key insights into the potential avenues for preventing and treating ovarian aging.Ruigong Zhu Xian Ji Xuan Wu Jiajing Chen Xuesong Li Hong Jiang Haiping Fu Hui Wang Zhe Lin Xin Tang Shixiu Sun Qingguo Li Bingjian Wang Hongshan Chen 2022Genes & Diseases2022,9,2:2
