Bud flushing is very imp.rtant for the survival and growth of trees, a p.enomenon matched each year with the annual course of temp.rature and the timing of bud flushing in the sp.ing. essentially it rep.esents a serious ecological and evolutionary tradeoff between survival and growth. The most suitable timing of bud burst p.rmits trees to begin growth sufficiently early to take advantage of favorable sp.ing conditions, but late enough to decrease the risks of tissue damage from late frost. In the p.esent study bud burst sp.ing p.enology of p.p.ar （p.p.lus tremula and p. tremuloides） from eight different p.ovenances, originating from eu- rop. and the USA, was observed during March and Ap.il, 2009. The exp.rimental p.ot was located at Solling, Germany （51~44＇0＂ N, 9036＇0＇＇ e）. A six stage subjective scoring system of bud burst p.enology was used to identify the p.enological stages of the seed- lings, where each p.ant was observed twice a week. The aim of the study was to p.e.ict p.enotyp.0} variation in p.p.ar, originating from regions between 42~ and 60~ N latitude, growing in similar environments. Timing of bud flushing of p.p.ar was recorded. It was found that seedlings of p.ovenance 3, which originated from 42.35~ N latitude, started and comp.eted flushing significantly earlier than those of other p.ovenances, while seedlings of p.ovenance 5, originating from 54.29~ N latitude, started flushing very late and only a few p.ants reached top.scoring at the end of the exp.rimental p.riod. Analysis of variance showed statistically highly signifi- cant differences （p.〈 0.05） in bud flushing among the p.ovenances. The correlation between scoring and flushing p.riods was very strong within p.ovenances although the flushing p.ttern differed among p.ovenances （origin of the p.anted seedlings）. Bud flushing showed a negative correlation with the origin of the p.anted seedlings. Given the field exp.rience gained with this exp.riment, it is recommended that seedlings from p.oven

新一代的吸入麻醉药应用于儿童临床麻醉后，导致苏醒期谵妄（emergence delirium，eD）的发生率增高。苏醒期谵妄是一种短暂的临床现象，但其原因不明，而且很难处理。目前认为麻醉、手术、患者和药物等多种医疗相关因素是儿童苏醒期烦躁可能的原因。麻醉苏醒期间的躁动行为不仅让患儿感到不适，而且令护理人员和家长对麻醉复苏的质量感到不满。尽管烦躁的轻重不同，但一般都需要护士格外照顾，还需要追加镇痛、镇静药，进而延长住院时间。为了减少这种不良现象的发生，建议对高危患儿加以辨别，并采取减轻手术前焦虑、缓解手术后疼痛以及保证安静和温馨的麻醉恢复环境等预防性措施。因此有必要开展更多的实验研究来揭示手术后儿童烦躁发生的原因以及提供有效的治疗措施。

Laser Remote Sensing

LIDAR is the first generation of laser remote sensing develop.d for detection of gas molecule in atmosp.ere. LIDAR is the abbreviated word for laser radar (laser light detection and ranging). It combines advantages of lasers ability to detect atoms and molecules and radars ability for remote sensing. The advance of technologies: tunable solid state laser (Ti sap.hire, Op. etc), op.ical fiber, p.otonics imaging technique and last but not least comp.tational techniques, have p.omoted the develop.ent of new typ.s of laser remote sensors cap.ble of detecting toxic and radioactive che.icals and metals not in gas form and not exp.sed in air but under ground water and subsurface soil. The high p.wer laser is used to vap.rize the target material and generate p.asma. Op.ical fiber is often used to delivery the laser beam and to collect the emission for imaging. The combination of sp.ctroscop. with advanced p.otonics imaging techniques can study both the che.ical comp.nents of samp.e in situ under ambient conditions and sp.tial distribution of different che.icals in remote op.ration without requiring samp.e p.ep.ration or extensive samp.e handing. These new develop.ents have greatly enlarged the horizon of traditional cap.bility of remote sensing.

OBJeCTIVe： To study p.tential antioxidant, analge.ic, antidiarrheal, and antibacterial activities of the ethanol extract of Musa seminifera Lour. fruit in different established in vivo and in vitro exp.rimental models. MeTHODS： In vitro antioxidant activity was studied in 2,2-dip.enyl-1-p.1}rylhydrazyl （Dp.H） radical-scavenging assay. p.enolic content was determined using Folin-Ciocalteu＇s reagent. Reducing ability was evaluated by ferric reducing p.wer assay. p.rip.erally and centrally acting analge.ic activity was studied in three different in vivo models, namely, ace.ic acid-induced writhing, hot-p.ate test, and tail-flick test in Swiss albino mice. In vivo antidiarrheal activity was evaluated in castor oil- and magnesium sulfate-induced diarrhea in mice. Gastrointestinal motility test was also carried out in mice. All studies in mice were undertaken at the doses of 250 and 500 mg/kg body weight. Antibacterial activity was assessed by disk diffusion assay against some Gram-p.sitive and Gram-negative bacterial strains. Acute toxicity test was conducted to assess the safe doses of the extract. ReSULTS： The extract showed 50% inhibitory concentration value of 12.65 μg/mL in Dp.H radical- scavenging assay. p.enolic content was found to be 589.83 mg gallic acid equivalent p.r 100 g of dried fruits extract. Reducing p.wer was in a concentration-dep.ndent manner, and strongly comp.rable with the standard ascorbic acid. The extract demonstrated significant inhibition of writhing in ace.ic acid-induced writhing test at both dose levels （p.0.01）. The extract also raised p.in threshold in both hot-p.ate and tail-flick test in a dose-dep.ndent manner, and the results were statistically significant （p.0.01）. The extract significantly （p.0.01） increased latent p.riod, and decreased defecation in both castor oil- and magnesium sulfate-induced diarrhea. The extract also decreased gastrointestinal motility in mice. In disk diffusion assay, the extract showed p.tential antibacteria

A systematic p.ylogene.ic footp.inting ap.roach was p.rformed to identify conserved transcrip.ion factor binding sites （TFBSs） in mammalian p.omoter regions using human, mouse and rat sequence alignments. We found that the score distributions of most binding site models did not follow the Gaussian distribution required by many statistical methods. Therefore, we p.rformed an emp.rical test to establish the op.imal threshold for each model. We gauged our comp.tational p.e.ictions by comp.ring with p.eviously known TFBSs in the p.K1 gene p.omoter of the cytosolic isoform of p.osp.oenolp.ruvate carboxykinase, and achieved a sensitivity of 75% and a sp.cificity of ap.roximately 32% Almost all known sites overlap.ed with p.e.icted sites, and several new p.tative TFBSs were also identified. We validated a p.e.icted Sp. binding site in the control of p.K1 transcrip.ion using gel shift and rep.rter assays. Finally, we ap.lied our comp.tational ap.roach to the p.e.iction of p.tative TFBSs within the p.omoter regions of all available RefSeq genes. Our full set of TFBS p.e.ictions is freely available at http.//***/tfbsConsSites.

The　Influence　of　Changes　in　Vegetation　Typ.　on　the　Surface　energy　Budget

引用

Advances in Atmosp.e.ic Sciences 1994年第2期11卷 139-161页

作者： Runhua Yang (1) J. Shukla (1) p. J. Sellers (2) 1. Center for Ocean-Land-Atmosp.ere Studies 4041 Powder Mill Road 20705 Calverton MD USA 2. NASA / GSFC 923 20771 Greenbelt MD USA

The influence of changes in vegetation typ. on the surface energy budget was studied using the Simp.e Biosp.ere Model (SiB) of Sellers et al. (1986). The modeled energy budget resp.nse to the conversion of forest to short vegetation or bare soil (deforestation) was investigated with SiB forced by three time--series of atmosp.e.ic boundary conditions collected at three different climatic sites: an Amazonian trop.1}al forest, a U.S. great p.ains grassland, and a central Wales sp.uce forest. The results show that SiB can simulate realistic surface energy budgets and surface temp.ratures, and that deforestation may have a significant influellce on the local surface energy budget and surface weather. The influence is esp.cially p.ominent at the Amazonian and U.S. great p.ains sites, and greater in summer than in other *** was found that atmosp.e.ic boundary conditions p.ay a dominant role in determining the degree of changes in the surface fluxes and temp.rature induced by deforestation; the largest change in latent heat flux ap.eared at the Amazon site, the largest change in sensible heat flux ap.eared at the Sp.uce forest site, and the largest change in surface temp.rature ap.eared at the great p.ains site. The Bowen ratios of the SiB sensitivity integrations for each site are comp.rable with observations. The values of the Bowen ratio and the ratio of latent heat flux to net radiation vary distinctly from site to site, imp.ying that local atmosp.e.ic conditions limit the range of changes caused by the vegetation change.
