| 3 | 新生代阿尔金山脉隆升历史的裂变径迹证据显示文摘10个片麻岩和花岗岩的磷灰石裂变径迹年龄值位于 3 5 .6~ 13 .6Ma之间 ,表明了阿尔金山脉的隆升开始于渐新世 ,并一直延续至中新世。山脉早期的隆升速率较低 ,后期可能存在一个快速的隆升时期 ;阿尔金山脉并非整体的均匀隆升 ,其内分布的NEE走向的断裂也局部控制了山体的隆升 ;如果山脉的隆升是阿尔金断裂左行走滑的结果 ,那么可推测阿尔金断裂大型左行走滑的起始时间应为渐新世。区域资料分析表明 ,青藏高原北缘在渐新世至中新世期间发生了大规模的、区域性的抬升。 | 陈正乐 张岳桥 王小凤 陈宣华 Washburn Z.

| 7 | Selective blockade of NF-kappa B by novel mutated I kappa B alpha suppresses CD3/CD28-induced activation of memory CD4(+) T cells in asthma显示文摘Background:Nuclear factor kappa B(NF-kappa B) overactivation plays a crucial role in T-helper 2 (Th2)-biased allergic airway inflammation by increased activation and decreased apoptosis of CD4(+) T cells. We have shown that targeted NF-kappa B suppression in dendritic cells by adenoviral gene transfer of a novel mutated inhibitor of NF-kappa B(I kappa B alpha) (AdI kappa B alpha M) contributes to T-cell tolerance, but the immunosuppressive action of AdI kappa B alpha M on memory(CD45RO(+)) CD4(+) T cells remains enigmatic. Methods:CD45RO(+) T cells from Dermatophagoides farinaei-sensitized asthmatic patients, untransfected or transfected with AdI kappa B alpha M or AdLacZ(beta-galactosidase) for 24 h, were stimulated with anti-CD3(1.0 mu g/ml) plus anti-CD28(0.5 mu g/ml) monoclonal antibody for an additional 24 h. I kappa B alpha M transgene expression and NF-kappa B activation were detected by polymerase chain reaction(PCR), reverse transcription-PCR(RT-PCR), Western blot analysis, and electrophoretic mobility shift assay. Phenotype and apoptosis were measured by flow cytometry, annexin V binding, and terminal deoxyribonucleotidyl transferase-mediated dUTP nick end labeling analyses. Cytokine production and cell proliferation were determined using enzyme-linked immunosorbent assay andH-3 thymidine incorporation. Results:A unique 801-bp I kappa B alpha M cDNA and a dose-dependent increase in I kappa B alpha M transgene expression were observed in AdI kappa B alpha M-transfected CD45RO(+) T cells. Significantly, AdI kappa B alpha M inhibited CD3/CD28-mediated NF-kappa B activation in CD45RO(+) T cells, leading to evident apoptosis, reduction of eotaxin, RANTES, Th1 interferon (IFN)-gamma and interleukin (IL)-2, and Th2 (IL-4, IL-5, and IL-13 despite a slight decrease in IL-10) cytokines and secondary proliferative response. AdI kappa B alpha M also upregulated cytotoxic T lymphocyte-associated antigen 4(CTLA-4) and downregulated CD69 besides no change in CD28. Conclusion:I kappa B alpha M might be beneficial to augment memory CD4(+) T-cell tolerance through modulating B7-CD28/CTLA-4 co-stimulatory pathways and NF-kappa B-dependent cytokine profiles in allergic inflammatory diseases including asthma. | Zhou,L.

| 13 | Model-Based Integrated Methods for Quantitative Estimation of Soil Salinity from Hyperspectral Remote Sensing Data:A Case Study of Selected South African Soils显示文摘Soil salinization is a land degradation process that leads to reduced agricultural yields. This study investigated the method that can best predict electrical conductivity (EC) in dry soils using individual bands, a normalized difference salinity index (NDSI), partial least squares regression (PLSR), and bagging PLSR. Soil spectral reflectance of dried, ground, and sieved soil samples containing varying amounts of EC was measured using an ASD FieldSpec spectrometer in a darkroom. Predictive models were computed using a training dataset. An independent validation dataset was used to validate the models. The results showed that good predictions could be made based on bagging PLSR using first derivative reflectance (validation R2 = 0.85), PLSR using untransformed reflectance (validation R2 = 0.70), NDSI (validation R2 = 0.65), and the untransformed individual band at 2257 nm (validation R2 = 0.60) predictive models. These suggested the potential of mapping soil salinity using airborne and/or satellite hyperspectral data during dry seasons. | Z. E. MASHIMBYE M. A. CHO J. P. NELL W. P. DE CLERCQ A. VAN NIEKERK D.

| 20 | Carbon nanotube and conducting polymer composites for supercapacitors显示文摘Composites of carbon nanotubes and conducting polymers can be prepared via chemical synthesis, electrochemical deposition on pre- formed carbon nanotube electrodes, or by electrochemical co-deposition. The composites combine the large pseudocapacitance of the conducting polymers with the fast charging/discharging double-layer capacitance and excellent mechanical properties of the carbon nanotubes. The electrochemically co-deposited composites are the most homogeneous and show an unusual interaction between the polymer and nanotubes, giving rise to a strengthened electron delocalisation and conjugation along the polymer chains. As a result they exhibit excellent electrochemical charge storage properties and fast charge/discharge switching, making them promising electrode mate- rials for high power supercapacitors. | Daniel Jewell George Z.
