Sclerotinia sclerotiorum(Lib) de Bary,a pathogen which can infect more than 400 plant species and cause serious losses of crop yield,produces a toxin——oxalic acid(OA) in pathogenesis and pure *** studies indicated that OA plays a important role in sclerotinia *** objectives of the studies are to screen microbes which utilize effectively OA and further clone its gene(s) for improvement of both plants for resistance and biocontrol *** detoxification of pathogenic toxin by plants or microbes is a new strategy for disease control.

全球卫星导航系统(Global Navigation Satellite System,GNSS)的散射信号作为一项新的遥感技术日益受到关注,目前已经成功的应用到海洋高度测量中,但由于陆地表面特性复杂,使基于GNSS的陆地表面高度计的设计一直是个难点。根据GPS信号的特点,推导了GPS地面散射回波信号的数学方程,建立了能反映陆地表面特性的GNSS-R双站雷达模型,从而设计了以GPS卫星作为照射源,接收机置于飞行器上,利用GPS散射信号测量陆地上空飞行器高度的仿真系统。通过对仿真结果的分析,验证了模型的有效性,也为后续的GNSS-R陆地高度计的优化设计提供了依据。

Objective To estimate the predictive value of double fluorescence [acridine orange （AO）/propidium iodide （PI）] staining results for fertilization rate and clinical outcomes and analyze the correlation between the results of AO/P1.staining and sperm apoptosis. Methods A prospective study was carried out, 2.5 infertile couples remedied using traditional in vitro fertilization （IVF） were included. Semen collected from 2.5 patients were stained by fluorescence dye, AO and PL at the same time the spermatozoa apoptosis rate was calculated by using flow cytometry to detect the rate of Annexin V＋/ PI- . The result of fluorescence was divided into 3 groups as green （G）, yellow （Y） and red （R） according to the color of fluorescence. The correlation between the percent of the 3 colors and clinical outcomes and spermatozoa apoptosis rate was evaluated. Results Significant negative correlation was observed between the percentage of Y and fertilization rate （r= -0.42. P=0.04）, no significant correlation was observed between the percentage of G, R and fertilization rate. The percentage of G, Y, R was not significantly different between pregnant patients and non-pregnant patients, respectiw,ly, while the percentage of Y was significant different between miscarriage patients and liveborn patients （r=0.6L P=0.01. and no significant difference exist in the percentage of G and R between liveborn patients and miscarriage patients. There was a significant positive correlation between the percentage of Y and the rate of Annexin V＋/ PI （r=0.53, P=0.04）, and no significant correlation was shown between the percentage of G, R and the rate of Annexin V＋/ PI-.Conclusion The percentage of yellow group of double fluorescence （AO/PI） staining will affect the fertilization rate and the miscarriage rate, and this group of spermatozoa may be connected with the spermatozoa apoptosis.

The main results are as follows:（1. Reactiveation with a contextual recall destabilized an established mCPA,but morphine CPP（mCPP） needs contextual and drug to reactive.（2.β-Adrenergic receptors in the BLA mediate reconsolidation of mCPA,but not mCPP.（3） No effect was observed on a-adrenergic receptors on drug-related memory *** of B-adrenergic receptors of BLA are different on the reconsolidation of mCPA and mCPP.
