| 2 | Rainfall interception by sand-stabilizing shrubs related to crown structure显示文摘On the edge of the Tengger Desert in northern China,revegetation has changed the landscape from moving dunes to stabilized dunes covered by shrubs,which further modifies the pattern of rainfall redistribution.To study rainfall interception loss by shrubs and its relationship to rainfall properties and crown structure,throughfalls passing through crowns of Artemisia ordosica Krash.and Caragana korshinskii Kom.were measured using nine PVC cups under the canopy of each of the two shrubs during 73 rain events over a three-year period,with total rainfall of 260.9 mm.Interception losses of gross rainfall by A.ordosica and C.korshinskii account for 15% and 27% of the total on a crown area basis,and 6% and 11% on a ground area basis,respectively.Individual throughfall(T) and interception(I) were significantly related to rainfall amount(Pg),duration(D),and intensity(R).Ratios of throughfall to rainfall(T/Pg) and interception to rainfall(I/Pg) were not only significantly related to Pg,D,and R,but also to shrub species,and interactions of species with crown volume(CV) and leaf area index(LAI).Under most rain events,interceptions by C.korshinskii with greater CV and LAI were significantly higher than those by A.ordosica,and more rainfall interception occurred at locations closer to the stems of the two shrubs.For C.korshinskii,I/Pg had a significant positive linear relation with CV and LAI,while T/Pg had a significant negative linear relation with them.CV has a greater influence on T/Pg and I/Pg than does LAI.Using a regression method,canopy water storage capacities are estimated to be 0.52 and 0.68 mm,and free throughfall coefficient to be 0.62 and 0.47 for A.ordosica and C.korshinskii,respectively. | ZhiShan Zhang 1*,XinRong Li 1,XueJun Dong 2,XiaoHong Jia 1,MingZhu He 1,HuiJuan Tan 1 1.Shapotou Desert Research and Experiment Station,Cold and Arid Regions Environmental and Engineering Research Institute,Chinese Academy of Sciences,Lanzhou,Gansu 730000,China.2.Central Grasslands Research Extension Center,North Dakota State University,Streeter,ND 58483,USA. | 2009 | Research in Cold and Arid Regions2009，1，2： | 9 |

| 4 | Fenton Reagent Generated in Electrolysis Cell and Its Usage in Degradation and Decolorization of Dyes显示文摘The Electro-chemistry process to produce Fenton reagents has been described. The in situ oxidation of dyes, acid chrome and alizarin red(Fenton reagents) with electrogenerated hydroxyl radicals was investigated. The \{ I-V \} cyclic voltammograms were measured. The redox peaks of the dyes were not observed in the treated dye solutions instead of a couple of O2/H2O2 redox peaks. The IR results indicate that acid chrome dye was decomposed into naphthylamine and phenol aminophenol sulfonic acid. The degradation and the decolorization of the dyes were comfirmed by the visible spectrum and the chemical analysis. The COD cr removing rate was close to 80%. | CHEN Zhen ** , ZHENG Xi, CHEN Ri-yao, LAN Rui-fang, LIN Zhi-hong and CHEN Yu-feng Experiment Center, Fujian Normal University, Fuzhou 350007, P. R.

| 5 | Immunization of mice with cells from juvenile worms of Schistosoma japonicum provides immunoprotection against schistosomiasis显示文摘To validate the protective efficacy against schistosomiasis by immunization with cells from juvenile Schistosoma japonicum in a murine model and to analyze possible factors related to protection, in this study, two independent repeated vaccination trials were performed. After three subcutaneous vaccina- tions, in trial one, in the absence of adjuvant, primary juvenile worm cells (pJCs) from S. japonicum induced remarkable average reductions in worm burden (54.3%), liver eggs per gram (LEPG) load (59.8%) as well as egg granulomas size (66.5%) compared to PBS control group (P<0.01), which were significantly higher than those elicited by fractions of juvenile worm cells (JCFs) or fractions of juvenile worms (JWFs) (P<0.05). Non-cell components of worms (WNCs) showed no significant protection. In trial two, compared to PBS control group, significant protective effect was also observed for cultured juvenile worm cells (cJCs) from S. japonicum with 58.4% worm reduction and 68.1% LEPG reduction (P<0.01). However, cultured adult worms cells (cACs) showed significantly higher worm burden (P<0.05) and egg burden (P<0.01) when compared to cJCs. Immunological analysis of trial two revealed that cJCs engendered a Th1-biased mixed Th1/Th2 type of immune response while cACs elicited a Th2-type response. Our data indicated that immunization with both primary and cultured cells from S. japonicum juvenile worms provided high immunoprotection, for which the physical character of immunogens, stage-specific parasite and the type of immune response induced might be responsible, suggesting that vaccination with whole cells from S. japonicum larvae is a promising approach to produce protec- tive immunity against schistosomiasis. | ZENG TieBing1,2, CAI LiTing1, ZENG QingRen1, YANG ShengHui1, YU Rong1, LI YanQin1, FANG HuiLong1, LI BenWen3 & ZHANG ShunKe1 1 Cell & Molecular Biological Experiment Center and Department of Parasitology, Xiangya School of Medicine, Central South Uni- versity, Changsha 410013, China 2 Institute of Pathogenic Biology, Medical College, Nanhua University, Hengyang 420001, China 3 Infectious Diseases Division, Washington University School of Medicine, Washington 63110, USA | 2007 | Science China(Life Sciences)2007，50，6： | 6 |
| 6 | EFFECTIVE DISCHARGE CALCULATION GUIDE显示文摘This paper presents a procedure for calculating the effective discharge for rivers with alluvial channels. An alluvial river adjusts the bankfull shape and dimensions of its channel to the wide range of flows that mobilize the boundary sediments. It has been shown that time-averaged river morphology is adjusted to the flow that, over a prolonged period, transports most sediment. This is termed the effective discharge. The effective discharge mayo be calculated provided that the necessary data are available or can be synthesized. The procedure for effective discharge calculation presented here is designed to have general applicability, have the capability to be applied consistently, and represent the effects of physical processes responsible for determining the channel. dimensions. An example of the calculations necessary and applications of the effective discharge concept are presented. | D. S. BIEDENHARN,C. R. THORNE, P.J.SOAR. ,R.D.HEY, and C. C.

| 8 | The ecohydrology of the soil-vegetation system restoration in arid zones: a review显示文摘Arid zones, which cover approximately 40 percent of the earth's land surface, support complicated and widely varied ecological systems. As such, arid zones are an important composition of the global terrestrial ecosystem, and water is the key and abiotic lim-ited factor in ecosystem-driven processes in these areas. Ecohydrology is a new cross discipline that provides, in an objective and comprehensive manner, novel ideas and approaches to the evaluation of the interaction and feedback mechanisms involved in the soil-vegetation systems in arid zones. In addition, ecohydrology provides a theoretical basis of ecological restoration that is cen-tered on vegetation construction. In this paper, long-term monitoring and local observations in the transitional belt between a de-sertified steppe and a steppified desert at the Shapotou Desert Research and Experiment Station, Tengger Desert, in northern China, were evaluated. The primary achievements and related research progress regarding ecohydrology in arid zones were analyzed and summarized, as a keystone, and the response of soil ecohydrological processes to the changes in the species composition, structure, and function of sandland vegetation was discussed. Meanwhile, the long-term ecological effects and mechanism of regulation of vegetation on soil habitat and on water-cycling were considered. As a vital participant in the ecohydrological processes of soil-vegetation systems, the studies on biological soil crusts was also summarized, and related theoretical models of restoration based on the water balance was reviewed. | XinRong Li 1,2, ZhiShan Zhang 1,2, Lei Huang 1,2, LiChao Liu 1,2, XinPing Wang 1,2 1.

TEA (10mmol/L), a nonselective potassiumchannel blocker significantly inhibited hyposmoticmembrane stretch-induced hyperpolarization. After KCIin the pipette and NaCI in the external solution werereplaced by CsCI to block the potassium current,hyposmotic membrane stretch depolarized the membranepotential from -60.0 mV±-1.0mV to -44.8 mV±2.3mV(P<0.05), and atropine (1 pmol/L) inhibited thedepolarization of the membrane potential. Muscarinicreceptor agonist Carbachol depolarized membranepotential from -60.0mV±1.0mV to -50.3 mV±0.3mV(P<0.05) and hyposmotic membrane stretchpotentiated the depolarization. Carbachol inducedmuscarinic current (Icch) was greatly increased byhyposmotic membrane stretch.CONCLUSION: Hyposmotic membrane stretchpotentiated muscarinic receptor agonist-induceddepolarization of membrane potential, which is relatedto hyposmotic membrane stretch-induced increase ofmuscarinic current. | Lin Li Nan-Ge Jin Lin Piao Zheng-Yuan Jin Ying Li Wen-Xie Xu Department of Physiology,Yanbian University College of Medicine,Yanji 133000,Jilin Province,China Ming-Yu Hong Wen-Xie Xu Center of experiment,Affiliated Hospital of Yanbian University College of Medicine,Yanji 133000,Jilin Province,China | 2002 | World Journal of Gastroenterology2002，8，4： | 3 |
| 10 | LABORATORY MEASUREMENTS IN SINE-GENERATED MEANDERING CHANNELS显示文摘The patterns (In flow plan) of rough turbulent steady flows in sine-generated meandering streams are investigated experimentally. The flow cross-section is rectangular, the flow width is uniform, the channel bed is flat; the plan shape is sine-generated. In contrast to previous works, where the computed flow patterns were of the same character, irrespective of the sinuosity of the channel, it is found, on the basis of present experiments, that every different Plan geometry of a meandering flow has its own flow picture. In the case of 'small' sinuosity, the flow convectively accelerates at the inner bank between the crossover-and apexsections; if, however, the sinuosity is 'large', the now convectively decelerates in the same region. The convergence-divergence areas (in flow Plan) of the present flows are in coincidence with the location of erosion-deposition zones in meandering streams, confirming that the convective behaviour of the vertically-averaged flow alone is sufficient to induce the bed and bank deformation. | A.

| 11 | Quantitative detection of ING1 mRNA under different gene regulation based on molecular beacon显示文摘The effects of drug treatment, gene transfection, and p53 RNA interference (RNAi) on level of ING1 mRNA in tumor cells were quantitatively detected with the help of ING1 molecular beacon (MB)/cRNA standard curve based on MB detection technology. Results showed that the level of ING1 mRNA could be upregulated by 5-FU treatment or ING1 transfection in low expression cell line of MCF-7 and be inhibited by silencing p53 with RNAi technology in normal expression cell line of CNE2. The level of ING1 varied from 7.7×10?16 to 53.4× 10?16 mol/μg total RNA of tumor cells. The results not only provided evidence for the regulation effects of gene expression but also were applied to investigat- ing the interaction of multigenes on signal transduc- tion pathway. | LIU Bin1,2,3,4, WANG Kemin1,2,3,4, XIAO Zhiqiang5,6, WANG Wei1,3,4, TAN Weihong1,2,3,4, SUN Yi5,6, TANG Hongxing1,3,4 & YANG Xiaohai1,3,41.
