BACKGROUND： Previous studies have focused on gene expression acutely following stroke onset. However, there have been a few reports of gene expression during later stages of cerebral infarction. OBJECTIVE： To determine gene expression profiling in the peri-infarct brain cortex 7 days after ischemia in a rat model of cerebral infarction in renovascular hypertensive rats. DESIGN, TIME AND SETTING： An in vivo, molecular experiment was performed at the Experimental Animal Center of sun Yat-sen University and CapitalBio, Beijing, China between February 2004 and August 2005. MATERIALS： A 70-mer oligo chip containing 5 705 rat genes was supplied by CapitalBio, Beijing, China; and the Oligo rat gene bank was provided by Qiagen, the Netherlands. METHODS： Six Sprague Dawiey rats were utilized to establish a stroke-prone renovascular hypertensive model using the two-kidney and two-clip method. The rats were subsequently randomly assigned to two groups： middle cerebral artery occlusion and sham-operation, with three rats in each group. The middle cerebral artery occlusion model was induced by intraluminal suture method. Incisions were sutured following isolation of carotid arteries in the sham-operation group. MAIN OUTCOME MEASURES： Total RNA was extracted from the peri-infarct cerebral cortex 7 days after surgery. Following fluorescent labeling, RNA was hybridized to an Oligo chip containing 5 705 genes and was then scanned. Images were collected and the differentially expressed genes （number and category） were selected by data analysis. RESULTS： A total of 174 genes were upregulated, and 23 were downregulated, in the peri-infarct cerebral cortex 7 days after ischemia. The upregulated genes were distributed among 12 functional categories, and the downregulated genes belonged to categories of transport, transcription regulators, signals, response to stress, metabolism, and cell adhesion. The expression of some cytoskeletal genes was upregulated, including VIM, A2M, B2M, ACTR3,

Forest losses or gains have long been recognized as critical processes modulating the carbon flux between the biosphere and the atmosphere. Timely, accurate and spatially explicit information on forest disturbance and recovery history is required for assessing the effectiveness of existing forest management. The major objectives of our research focused on testing the mapping efficacy of the vegetation change tracker （VCT） model over a forested area in China. We used a new version of VCT algorithm built upon the Landsat time series stacks （LTSS）. The LTSS consisted of yearly image acquisitions to map forest disturbance history from 1987 to 2011 over the Ning-Zhen Mountains, Jiangsu Province of east China. The LTSS consisted of TM and ETM＋ scenes with different projec- tions due to distinct data sources （Beijing remote sensing ground station and the USGS EROS Center）. The valida- tion results of the disturbance year maps showed that most spatial agreement measures ranged from 70 to 86 %, comparable with the VCT accuracies reported for many places in USA. Very low accuracies were identified in 1995 （38.3 %） and 1992 （56.2 %） in the current analysis. These resulted from the insensitivity of the VCT algorithm to detect low intensity disturbances and also from the mis- registration errors of the image pairs. Major forest distur- bance types existing in our study area were identified as agricultural expansion （39.8 %）, urbanization （24.9 %）, forest management practice （19.3 %）, and mining （12.8 %）. In general, there was a gradual decreasing trend in forest cover throughout this region, caused principally by China＇s economic, demographic, environmental and political policies and decisions, as well as some weather events. While VCT has largely been used to assess long term changes and trends in the USA, it has great potential for assessing landscape level change elsewhere throughout the world.

A method is proposed to select the target sequence for a J 2-perturbed multiple debris rendezvous mission aimed at removing dozens of debris from several thousand debris candidates running on sun-synchronous orbits(SSO).The solving methodology proceeds in two steps:Firstly,the variance of the right ascension of ascending node(RAAN)of the debris group is used for narrowing down the potential debris candidate;secondly,the debris of the candidate group that has closest RAAN to the current debris is chosen as the next *** low thrust near-minimum-fuel trajectories of each rendezvous leg are obtained by the indirect optimization *** proposed approach is demonstrated for the problem of the 8th China Trajectory Optimization Competition(CTOC).The radar cross section(RCS)of the debris is also considered in the first step since the primary performance index of the competition is to maximize the total RCS of the debris *** results show that the proposed approach achieves better performance within a competition *** the many rendezvous sequences found,the best one submitted for the competition obtained a total RCS of 184 by accomplishing rendezvous with 70 debris within a transfer duration of one year.
