2The Impacts of Maternal Gestational Diabetes Mellitus (GDM) on Fetal Hearts显示文摘Objective To evaluate the fetal cardiac function in gestational diabetes mellitus (GDM) pregnancies under different maternal glycemic controls.Methods Forty four GDM mothers received 78 fetal echocardiographic evaluations at three gestational periods (<28,28-34 and ≥34 weeks) and were divided into poorly-(DM1) and well-(DM2) controlled groups according to their glycemic control at examination.Seventy uncomplicated mothers were selected as controls.Parameters of fetal cardiac anatomy and function were measured and analyzed.Results GDM fetuses' cardiac ventricular walls were thicker than controls',and the differences between DM1 and DM2 were not significant except for end-diastolic left ventricular walls.In both GDM groups,the aortic flow velocities increased earlier than pulmonary artery and DM1 fetuses changed earlier than DM2 ones.GDM fetuses' left atrial shortening fraction was smaller than the controls' in the period of ≥34 weeks and negatively correlated with thicknesses of left ventricular walls and interventricular septum in DM1 fetuses (r=-0.438 and -0.506).The right ventricular diastolic function in DM1 and DM2 fetuses decreased after the period of 28-34 weeks and in the period of ≥34 weeks respectively.Tei index of both left and right ventricles increased in DM1 group after the period of<28 weeks and in DM2 group only in the period of ≥34 weeks,with no significant differences between DM1 and DM2 groups in this period.Conclusion Fetuses of GDM mothers showed cardiac function impairments.Good maternal glycemic control may delay the impairments,but cannot reduce the degree.Some cardiac changes in GDM fetuses were similar to those in pregestational diabetic pregnancies except for several parameters and their changing time.CHU Chen GUI Yong Hao PEN Yun Yun SHI Li Ye 2012Biomedical and Environmental Sciences2012,25,1:20
3A win-win technique of stabilizing sand dune and purifying paper mill black-liquor显示文摘The principle and technique were reported here to produce lignin-based sand stabilizing material (LSSM) using extracted lignin from black liquor of straw paper mills. Field tests using LSSM to stabilize and green sand dunes were started in 2002. The field experiment was carried out in August 2005 when the newly formed plant community was 3 years old. The results from the comprehensive field experiment demonstrated that unlike polyvinyl acetate or foamed asphalt commonly used for dune stabilization, LSSM was plant- friendly material and could be used in combination with seeding and planting of desert species. With the help of LSSM, the desert species (i.e., Agriophyllum squarrosum (L.) Moq. and Artemisia desertorum Spreng. etc.) could be used to form community in 2-3 yeas and to stabilize sand dune effectively. The newly formed community was sustainable under an extremely dry climate condition. The organic matter and total nitrogen in the soil increased significantly as the community were formed, while the change in P and K contents in the soil was negligible.WANG Hanjie Penning de Vries FRITS JIN Yongcan 2009Journal of Environmental Sciences2009,21,4:14

6Formation of active oxygen species on single-atom Pt catalyst and promoted catalytic oxidation of toluene显示文摘Catalytic oxidation of toluene over noble metal catalysts is a representative reaction for elimination of volatile organic compounds(VOCs).However,to fully understand the activation of molecular oxygen and the role of active oxygen species generated in this reaction is still a challenging target.Herein,MgO nanosheets and single-atom Pt loaded MgO(Pt SA/MgO)nanosheets were synthesized and used as catalysts in toluene oxidation.The activation process of molecular oxygen and oxidation performance on the two catalysts were contrastively investigated.The Pt SA/MgO exhibited significantly enhanced catalytic activity compared to MgO.The oxygen vacancies can be easily generated on the Pt SA/MgO surface,which facilitate the activation of molecular oxygen and the formation of active oxygen species.Based on the experimental data and theoretical calculations,an active oxygen species promoted oxidation mechanism for toluene was proposed.In the presence of H2O,the molecular oxygen is more favorable to be dissociated to generate•OH on the oxygen vacancies of the Pt SA/MgO surface,which is the dominant active oxygen species.We anticipate that this work may shed light on further investigation of t10.1007/s12274-020-2765-1he oxidation mechanism of toluene and other VOCs over noble metal catalysts.Shunzheng Zhao Yanfeng Wen Xijun Liu Xianyun Pen Fang Lü Fengyu Gao Xizhou Xie Chengcheng Du Honghong Yi Dongjuan Kang Xiaolong Tang 2020Nano Research2020,13,6:12
7Effects of Land Use on Heavy Metal Accumulation in Soils and Sources Analysis显示文摘Heavy metal accumulation and its influential factors were studied in the different land use soils, which would provide a theoretical basis for controlling the content of heavy metals in soils. To identify the effects of land use on the accumulation of heavy metals in soils, 148 soil samples were collected from four land use patterns including greenhouse field, uncovered vegetable field, maize field, and forest field in Siping area of Jilin Province, China, and Cr, Ni, Cu, As, Cd, Pb, and Zn contents of those samples were determined with ICP and ICP-Mass. The result showed that there was a rather large difference in effects of the accumulation of Cr, Ni, Cu, As, Cd, and Zn in soils under different land use patterns, except Pb. Based on the assessment which compared with background concentrations in soil, the higher accumulation of heavy metals was found in greenhouse and uncovered vegetable field, much less in maize field and forest field. The mean contents of heavy metals in soils from high to low were arranged in order of greenhouse field, uncovered vegetable field, maize field, and forest field. Cd and Cu had relatively serious accumulation in soils compared to Cr, Ni, As, and Zn. The mean content of Cd in greenhouse field was 0.467 mg kg-1, which exceeded the grade II of the Chinese Soil Quality Criterion GB15618-1995 (6.5 < pH < 7.5) for Cd standard of 0.3 mg kg-1, while it was 5.2 times of Cd standard in the forest fields. The mean contents of Cr, Ni, Cu, As, Pb, and Zn in soils under four land use patterns were lower than the grade II of the Chinese Soil Quality Criterion. Compared with the soil cultivated years, the agricultural chemical compounds and manures application, especially the quality and quantity of applied fertilizer was one of the main reasons for leading to different accumulation of heavy metals in soils under the studied land use patterns. The accumulation of heavy metals, such as Cr, Ni, Cu, As, Cd, and Zn in soils was significantly affected by land use patterns, among them the accumulation of heavy metals in greenhouse soils was higher than others. It is suggested that the application of chemical fertilizer, organic fertilizer, and pesticides with high contents of heavy metals should be avoided to prevent the accumulation of heavy metal and keep high quality soils for sustainable use.BAI Ling-yu ZENG Xi-bai LI Lian-fang PEN Chang LI Shu-hui 2010Agricultural Sciences in China2010,9,11:11
8TraitMill:禾谷类作物高产基因发掘的引擎(英文)显示文摘转基因技术是研究植物发育的有效的途径。比利时的作物设计公司(CropDesign)成功研制出称为TraitMill的技术平台,TraitMill平台不仅是一个能够大规模开展转基因和植株评价的高通量的技术平台,而且还是一个在植物表型上鉴定基因和基因组合的非常有用的工具。无论是在理想的植株生长条件下,还是在不同非生物逆境或营养胁迫条件下,利用TraitMill平台每年可成功地鉴定成百个不同的“启动子—基因”组合。基于对水稻生长发育的特别设计和高精度的测量方法改造,TraitMill平台已经全面应用于水稻转基因及其性状的评价。迄今为止,TraitMill平台是唯一一个将转基因技术和植株性状自动化评价系统相结合的技术平台。显然,应用于改良禾谷类作物产量基因的鉴定,TraitMill平台具有独特的优势。Christophe Reuzeau Jan Pen Valérie Frankard Joris de Wolf Rindert Peerbolte Willem Broekaert Wim van Camp 方宣钧(推荐人) 2005分子植物育种2005,3,5:10
9Specifying Requirements of Real-Time System with Rules and Templates显示文摘This paper presents a model specifying requirements of real-time systems. Dif ferent from existing researches, this model mainly uses rules and templa tes to represent hierarchical FSMs (Finite State Machine). In this model, one ru le corresponds to one state transition of FSM and one template corresponds to on e FSM. Rules and information with respect to a FSM can be written in a template. So templates include not only state diagrams, but also information that can not be described by FSM, such as performance requirements. The specification using this model consists of a collection of templates and it is easy for users to und erstand and to review. After introduced the related researches and principles of the model, this paper specifies requirements of a real-time system with this m odel, and discusses characters of this model in the end.Wu Guo-qing Xiao Hai-feng Zheng Pen Ying Shi 2000Wuhan University Journal of Natural Sciences2000,5,3:8
10Multiscale simulation of nanometric cutting of single crystal copper——effect of different cutting speeds显示文摘A multiscale simulation has been performed to determine the effect of the cutting speed on the deformation mechanism and cutting forces in nanometric cutting of single crystal copper.The multiscale simulation model,which links the finite element method and the molecular dynamics method,captures the atomistic mechanisms during nanometric cutting from the free surface without the computational cost of full atomistic simulations.Simulation results show the material deformation mechanism of single crystal copper greatly changes when the cutting speed exceeds the material static propagation speed of plastic wave.At such a high cutting speed,the average magnitudes of tangential and normal forces increase rapidly.In addition,the variation of strain energy of work material atoms in different cutting speeds is investigated.Hongmin PEN Qingshun BAI Yingchun LIANG Mingjun CHEN 2009Acta Metallurgica Sinica(English Letters)2009,22,6:6
11Quantum entanglement of the binomial field interacting with a cascade three-level atom beyond the rotating wave approximation显示文摘In this paper, the quantum entanglement between a single mode binomial field and a cascade three-level atom is calculated mechanically without the rotating wave approximation. The numerical results indicate that the quantum entanglement at the first few periods is reduced notably due to the fact that the atom is initially in the superposition state. With increasing field parameter , the period of the entanglement evolution becomes obvious and the quantum decoherence phenomenon emerges in a short time.PEN XueZao CONG HongLu WANG XuWen XIA JianPing 2011Science China(Physics,Mechanics & Astronomy)2011,54,9:6

18β-receptor blocker influences return of spontaneous circulation and chemical examination in rats during cardiopulmonary resuscitation显示文摘Objective:We investigated the influence of β-receptor blocker metoprolol on return of spontaneous circulation(ROSC) during cardiopulmonary resuscitation(CPR) in rats with induced myocardial infarction(MI).Methods:Male Sprague-Dawley rats were randomly divided into three groups:the sham-operated group,the MI group without metoprolol,which was fed the vehicle,and the MI+metoprolol group receiving intragastric metoprolol.Each group was further divided randomly into three subgroups,depending on the dosage of epinephrine administered during subsequent CPR applied after the induction of asphyxial cardiac arrest.Results:The ROSC rate was significantly decreased in the low dose subgroup of MI group,unchanged in the medium dose subgroup of MI group,and significantly decreased in the high dose subgroup of MI group,compared with the same dose subgroup of sham-operated group.MI+metoprolol group had a lower ROSC rate than MI group in the medium dose subgroup,and a higher ROSC rate than MI group in the high dose subgroup.There was no difference in blood K+ values of successful rats between MI group and MI+metoprolol group.The rats with successful CPR had lower blood K+ values than rats with unsuccessful CPR in each of the three treatment groups.Conclusions:Metoprolol administered to MI rats over a long period significantly improved ROSC rates under an appropriate dose of epinephrine during CPR.An increasing high blood K+ value would attenuate the rate of a successful CPR.Xiao-jing ZHAO Zhuo PEN Ping LI Er-xiu CHEN Jian LIU Yan-xia GAO Yun-xia REN Li-jun LI 2013Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013,14,6:3
19Resveratrol as an inductor of autophagy: is there a unique pathway of activation?显示文摘Autophagy is a process of cellular degradation for the removal of damaged components and eventual recycling of the resulting molecules that help to the maintenance of cellular homeostasis.Through this pathway,proteins with relatively long half-life and whole organelles(e.g.,mitochondria,peroxisomes,and ribosomes)are degraded in the cytoplasm for the continuous turnover of cellular structures to facilitate their renewal.However,the beneficial effect of autophagy goes beyond cellular“cleaning”and resides to a large extent on its ability to recycle cell components back into the cytosol.Thus,autophagy is a fundamental mechanism to regulate cellular functions,including DNA repair,proliferation,differentiation,embryonic development,and the immune response.Narayana Pineda-Ramírez Penélope Aguilera 2021Neural Regeneration Research2021,16,1:3
