1Mineral weathering and element cycling in soil-microorganism-plant system显示文摘Soil is an essential part of the critical zone,and soil-microbe-plant system serves as a key link among lithosphere,biosphere,atmosphere and hydrosphere.As one of the habitats with the richest biodiversity,soil plays a critical role in element biogeochemistry on the earth surface(weathered crust).Here we review the soil biological processes that are relevant to mineral weathering,element cycling,and transformation,with an emphasis on rock weathering mediated by soil microbes,plant root and the rhizosphere.ZHU YongGuan DUAN GuiLan CHEN BaoDong PENG XinHua CHEN Zheng SUN GuoXin 2014Science China Earth Sciences2014,57,5:14
2Lotus seed skin proanthocyanidin extract exhibits potent antioxidant property via activation of the Nrf2-ARE pathway显示文摘Lotus seed is well known as traditional food and medicine,but its skin is usually discarded.Recent studies have shown that lotus seed skin contains a high concentration of proanthocyanidins that have multi-functions,such as antioxidation,anti-inflammation,and anti-cancer effects.In the present study,we aimed to isolate and purify the proanthocyanidins from lotus seed skin by acetone extraction and rotary evaporation,identify their chemical structures by HPLC-MS-MS and NMR,and further investigate the antioxidant properties of the extract purified by macroporous resin (PMR) from lotus seed skin both in vitro and in vivo.The results showed that PMR mainly contained oligomeric proanthocyanidins,especially dimeric procyanidin B1 (PB1),procyanidin B2 and procyanidin B4.Although it had limited ability to directly scavenge radicals in vitro,PMR could significantly enhance the expressions of antioxidant proteins via activation of nuclear factory-related factor 2 (Nrf2)-antioxidant response element (ARE) pathway in HepG2 cells.Molecular data revealed that PB1,a major component in PMR,stabilized Nrf2 by inhibiting the ubiquitination of Nrf2,which led to subsequent activation of the Nrf2-ARE pathway,including the enhancements of Nrf2 nuclear translocation,Nrf2-ARE binding and ARE transcriptional activity.Moreover,the in vivo results in high fat diet-induced mice further verified the powerful antioxidant property of PMR.These results revealed that lotus seed skin is a promising resource for functional food development.Tao Li Qili Li Weiguo Wu Yong Li De-xing Hou Hua Xu Baodong Zheng Shaoxiao Zeng Yang Shan Xiangyang Lu Fangming Deng Si Qin 2019Acta Biochimica et Biophysica Sinica2019,51,1:8
3Extended Jury criterion显示文摘In this paper,algebraic criteria are established to determine whether or not a real coefficient polynomial has one or two pairs of conjugate complex roots whose moduli are equal to 1 and the other roots have moduli less than 1 directly from its coefficients.The form and the function of the criteria are similar to those of the Jury criterion which can be used to determine whether or not all the moduli of the roots of a real coefficient polynomial are less than 1.ZHENG BaoDong 1,LIANG LiJie 1 & ZHANG ChunRui 2 1 Department of mathematics,Harbin Institute of Technology,Harbin 150001,China 2 Department of mathematics,Northeast Forestry University,Harbin 150040,China 2010Science China Mathematics2010,53,4:4
4Space efficient revocable IBE for mobile devices in cloud computing显示文摘.Dear editor,Revocation capacity is one of the main properties for an identity-based encryption(IBE),as in practice users’private keys are possibly leaked or expired.However,existing revocable IBE schemes[1–3]usually lack of short keys.Recently,Lin et al.[4]proposed a method to design space efficient revocable IBE scheme from non-monotonic key-policy attribute-based encryption scheme.But,it requires too many pairings(linear to the number of revoked users)to decrypt an IBE ciphertext.In this study,we overcome this problem by adopting the technique of server-aided revocation,recently proposed by Qin et al.[5]in ESORICS 2015.The main contribution is a new server-aided revocable IBE scheme,which can largely shift decryption overhead from local users to an untrusted cloud computing server,and significantly reduce the complexities of PKG’s(Private-Key Generator)key update information and server’s long-term identity-based public information(also called long-term transformation keys)with the comparison of previous(server-aided)revocable IBE schemes.Baodong QIN Ximeng LIU Zhuo WEI Dong ZHENG 2020Science China(Information Sciences)2020,63,3:3

6Structure elucidation and in vitro rat intestinal fermentation properties of a novel sulfated glucogalactan from Porphyra haitanensis显示文摘This study was to investigate the structure and rat fecal microbial fermentation properties of a polysaccharide fraction(PHP2)isolated from the red marine alga Porphyra haitanensis.PHP2 was characterized as a sulfated glucogalactan,with a hypothetical backbone structure of→4)Gα(1→6)G4 Sβ(1→4)Glc(1→and a side chain of Man(1→6)Glc.PHP2 had an irregular spherical chain conformation.The 16 S r RNA sequence analysis revealed that PHP2 modulated the rat fecal micro-flora composition,with a similar effect to inulin,changing the dominant genus(Lactobacillus and Escherichia-Shigella)and promoting the growth of organisms that degrade sulfur-containing polysaccharides,such as Desulfovibrio,Ruminococcaceae_UCG-005,and Ruminococcus_2.PHP2 can promote production of acetic,propionic and butyric acid by rat fecal micro-flora.Prediction of metabolic function suggested that PHP2 could modulate cholesterol metabolism.The sulfated glucogalactan fermentation behavior may be associated with its monosaccharide composition,chain branching and chain conformation.PHP2 appeared to have considerable potential as functional food,and was associated with sulfur-containing polysaccharides in general.Peilin Chen Lu Liu Zirun Cheng Yi Zhang Baodong Zheng Xiaoke Hu Hongliang Zeng 2023Food Science and Human Wellness2023,12,2:2

20The optimization of ultrasonic-microwave assisted synergistic extraction of Lotus plumule extract rich in flavonoids and its hypoglycemic activity显示文摘Lotus(Nelumbo nucifera Gaertn),a kind of perennial aquatic plant,is widely cultivated and consumed by people in Asian countries.Lotus plumule flavonoids(LPF)have been recognized as a hypoglycemic agent.LPF was optimally obtained using novel ultrasonic-microwave assisted synergistic extraction(UMSE)method by response surface methodology(RSM)on the basis of the results of single-factor experiments.Furthermore,the hypoglycemic activity of LPF was investigated by measuring the body weight,fasting blood glucose(FBG)level,and oral glucose tolerance test(OGTT)and analyzing the physiological indexes in streptozotocin-diabetic mice model.The optimum extraction conditions consisted of microwave power 355 W,ultrasonic power 423 W,extraction time 15 min,solid-liquid ratio 1:40,ultrasound/interval time 1/0,and ethanol concentration 70%with the maximum LPF yield of 2.62%.LPF supplementation significantly decreased the body weight,FBG,OGTT,serum total cholesterol(TC),serum total triglycerides(TG),and insulin levels,indicating the antidiabetic activity of LPF.This research verified that the UMSE technique was highly efficient to extract LPF to the maximum extent and the flavonoids from L.plumule exhibited hypoglycemic activity,which showed broad development and application prospects.Qiuzhe Li Xiaoqing Li Baodong Zheng Chao Zhao 2021Food Production, Processing and Nutrition2021,3,1:0
