| 2 | Emerging roles of cardiolipin remodeling in mitochondrial dysfunction associated with diabetes,obesity,and cardiovascular diseases显示文摘Cardiolipin(CL)is a phospholipid exclusively localized in inner mitochondrial membrane where it is required for oxidative phosphorylation,ATP synthesis,and mitochondrial bioenergetics.The biological functions of CL are thought to depend on its acyl chain composition which is dominated by linoleic acids in metabolically active tissues.This unique feature is not derived from the de novo biosynthesis of CL,rather from a remodeling process that involves in phospholipases and transacylase/acyltransferase.The remodeling process is also believed to be responsible for generation of CL species that causes oxidative stress and mitochondrial dysfunction.CL is highly sensitive to oxidative damages by reactive oxygen species(ROS)due to its high content in polyunsaturated fatty acids and location near the site of ROS production.Consequently,pathological remodeling of CL has been implicated in the etiology of mitochondrial dysfunction commonly associated with diabetes,obesity,heart failure,neurodegeneration,and aging that are characterized by oxidative stress,CL deficiency,and abnormal CL species.This review summarizes recent progresses in molecular,enzymatic,lipidomic,and metabolic studies that support a critical regulatory role of pathological CL remodeling as a missing link between oxidative stress and mitochondrial dysfunction in metabolic diseases and aging. | Yuguang Shi Department of Cellular and Molecular Physiology,P ennsylvania State University College of Medicine,Hershey,PA 17033,U.S.A. | 2010 | The Journal of Biomedical Research2010，24，1： | 5 |
| 3 | Management Strategies and Research Orientations of Forest Diseases and Pests in China显示文摘Forest diseases and pests are perceived as a growing hazard to China economy. It is a common conclusion that the actualities of forest pests in china are no effective measures to the old important pests, some secondary pests are ascending to chief pests, increasing devastation from exotic pests, frequent ecological pest eruption induced by environmental detriment and host-leading diseases to threaten the 'Western Development Project 'in China, which is the most important economical strategy to China; th... | ZHANG Xingyao LIANG Jun LU Quan YAN Donghui LUO Youqing XU Zhichun WEN Junbao1.

| 4 | Nitrite-derived nitric oxide by xanthine oxidoreductase protects the liver against ischemia- reperfusion injury显示文摘It was demonstrated that xanthine oxidoreductase (XOR), during ischemia, catalyzes the formation of nitric oxide (NO) from nitrite (NO2-) and this NO2--derived NO protects the isolated perfused rat heart against the damaging effects of ischemia-reperfusion (I/R) when conventional nitric oxide synthase (NOS) -dependent NO production is impaired. Liver is one of the organs with the highest XOR concentration. This study was designed to determine whether NO2--derived NO by XOR protects liver against I/R injury in vivo. For its minute amounts and active reactivity, NO can not be detected directly in real time in vivo by this time. We have to prove the above hypothesis indirectly. METHODS:Wistar rats were pretreated with saline, NOS inhibitor L-NAME (10 mg/kg intravenously), XOR inhibitor allopurinol (1.5 mg/kg orally), L-NAME +allopurinol and NO scavenger carboxy-PTIO (0.6 mg/kg intravenously) respectively (12 animals per group). And then, they were subjected to total liver ischemia for 40 minutes followed by reperfusion. Blood samples and liver tissues were obtained for analysis after 3 hours of reperfusion. Survival was also investigated. RESULTS:Allopurinol-treated animals exhibited further increased serum alanine aminotransferase (ALT) levels and liver myeloperoxidase (MPO) activities, but further decreased liver adenosine triphosphate (ATP) stores after I/R compared to saline-treated counterparts (830.5±108.3 U/L, 56.5±11.0 U/mg protein and 1.93±0.47 μmol/g vs. 505.8± 184.2 U/L, 41.5±10.2 U/mg protein and 3.05±0.55 μmol/g respectively, P<0.01, P<0.05 and P<0.01 respectively). The hepatocyte injury was further exacerbated and the overall survival rate was significantly decreased after I/R in animals given by allopurinol compared to those pretreated by saline (P<0.05). L-NAME and allopurinol co-treated animals exhibited more severe liver injury (P<0.05 and P<0.01) and a further decreased overall survival rate (P<0.05) compared to L-NAME or allopurinol alone-treated counterparts, but they were not different from carboxy-PTIO treated animals (P>0.05). CONCLUSION:NO2--derived NO by XOR in the hypoxic and acidic environment induced by hepatic I/R protects the liver against I/R injury in vivo. | Department of General Surgery ( Lu P, Wang CY and Chen DD), and Department of Radiology (Liu F), Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430022, China Cold Spring Harbor Laboratory, New York 11724, USA ( Yao Z) General Surgery Laboratory, Union Hospital, Tongji Medical College , Huazhong University of Science and Technology, Wuhan 430022 , China (Tian Y, Zhang JH and Wu YH) | 2005 | Hepatobiliary & Pancreatic Diseases International2005，4，3： | 4 |

| 6 | Validation and Scenario Analysis of a Soil Organic Carbon Model显示文摘A model developed by the authors was validated against independent data sets. The data sets were obtained from field experiments of crop residue decomposition and a 7-year soil improvement in Yixing City, Jiangsu Province. Model validation indicated that soil organic carbon dynamics can be simulated from the weather variables of temperature, sunlight and precipitation, soil clay content and bulk density, grain yield of previous crops, qualities and quantities of the added organic matter. Model simulation in general agreed with the measurements. The comparison between computed and measured resulted in correlation coefficient γ2 values of 0.9291 * * * (n = 48) and 0. 6431 * * (n = 65) for the two experiments, respectively. Model prediction under three scenarios of no additional organic matter input, with an annual incorporation of rice and wheat straw at rates of 6.75t/ha and 9.0t/ha suggested that the soil organic carbon in Wanshi Township of Yixing City would be from an initial value of 7.85g/kg in 1983 to 6.30g/kg, 11.42g/kg and 13g/kg in 2014, respectively. Consequently, total nitrogen content of the soil was predicted to be respectively 0.49g/kg,0.89g/kg and 1.01g/kg under the three scenarios. | HUANG Yao, LIU Shi-Hang, SHEN Qi-rong, ZONG Liang-gang, JIANG Ding-an and HUANG Hong-guang(College of Resource and Environmental Sciences , Nanjing Agricultural University, Nanjing 210095 , P,R.

The troughs in our observations are found to appear mainly in dusk sector, extending from late afternoon to pre midnight, with higher occurrence rate during equinox and winter. Simultaneous ion drift velocity in F region shows that the main trough minimum is mostly located at the equator ward edge of the plasma convection flow, rather than in the region where the largest ion flow are observed. | LIU Peng 1 ,MA Shu ying 1,2 ,K.

| 18 | Mssbauer Effect in Ultrafine Particles with Fe-C Solid Solution,γ-Fe and Fe_3C Phases显示文摘Ultrafine particles prepared by evaporating pure Fe in CH4 atmosphere using arc-dischargeheating method, were found to consist of Fe-C solid solution, γ-Fe and Fe3C phases. EfFect of annealing temperature on phase transformation and hyperfine interactions has been investigated by Mossbauer spectroscopy, X-ray diffraction (XRD), differential thermal analysis and thermogravimetry (DTA-TG), transmission electron microscopy (TEM), oxygen determination and vibrating sample magnetometer (VSM) measurements. It was observed that phase transformation of γ-Fe to α-Fe occurs during annealing in vacuum. The mechanism causing the change of hyperfine interactions with annealing temperature differs for Fe-C solution and interstitial compounds. DifFerence of hyperfine interactions of Fe-C solid solution in the starting sample and its annealed samples is ascribed to the improvement of activation of interstitial carbon atoms. Stress-relieving in structure of annealed Fe3C particle can result in a weak influence on hyperfine interactions. Parameters fitted to the Mossbauer spectra show the existence of superparamagnetism in all the samples. Absorbed and combined oxygen on particle surface of the starting sample were determined. | Xinglong DONG Zhidong ZHANG and Xinguo ZHAO (Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110015, China)Yuesheng CHAO (College of Science, Northeastern University, Shenyang 110006, China)Souri JIN and Weimin SUN (Lab. of Ultrafine P | 1998 | Journal of Materials Science & Technology1998，14，5： | 1 |
