| 1 | PslG, a self-produced glycosyl hydrolase, triggers biofilm disassembly by disrupting exopolysaccharide matrix显示文摘Biofilms 是在细胞外的矩阵嵌入的微生物的联系表面的社区。Exopolysaccharide 是在维持 biofilm 建筑学并且保护居民 biofilm 细菌免受抗菌剂和主人免疫者攻击的伤害的细胞外的矩阵的一个批评部件。然而,指向矩阵 exopolysaccharides 的自我生产的因素,仍然糟糕被理解。这里,我们显示出那 PslG,在 Pseudomonas aeruginosa 涉及关键 biofilm 矩阵 exopolysaccharide Psl 的合成的蛋白质,阻止 biofilm 形成并且拆卸存在在外长地供应的在 nanomolar 集中的分钟以内的 biofilms。PslG 的水晶结构显示 endoglycosidase 的典型特征。PslG 主要破坏 Psl 矩阵从 biofilms 驱散细菌。PslG 处理显著地提高 biofilm 敏感到抗菌素和巨噬细胞房间,导致在一只老鼠的改进 biofilm 清理植入感染模型。而且, PslG 对大量 Pseudomonas 种类显示出 biofilm 抑制和拆卸活动,显示它在与 biofilm 相关的复杂并发症作斗争的大潜力。 | Shan Yu Tiantian Su Huijun Wu Shiheng Liu Di Wang Tianhu Zhao Zengjun Jin Wenbin Du Mei-Jun Zhu Song Lin Chua Liang Yang Deyu Zhu Lichuan Gu Luyan Z Ma | 2015 | Cell Research2015，25，12： | 13 |
| 2 | Tea picking point detection and location based on Mask-RCNN显示文摘The accurate identification,detection,and segmentation of tea buds and leaves are important factors for realizing intelligent tea picking.A tea picking point location method based on the region-based convolutional neural network(R-CNN)Mask-RCNN is proposed,and a tea bud and leaf and picking point recognition model is established.First,tea buds and leaf pictures are collected in a complex environment,the Resnet50 residual network and a feature pyramid network(FPN)are used to extract bud and leaf features,and preliminary classification and preselection box regression training-performed on the feature maps through a regional proposal network(RPN).Second,the regional feature aggregation method(RoIAlign)is used to eliminate the quantization error,and the feature map of the preselected region of interest(ROI)is converted into a fixed-size feature map.The output module of the model realizes the functions of classification,regression and segmentation.Finally,through the output mask image and the positioning algorithm the positioning of the picking points of tea buds and leaves is determined.One hundred tea tree bud and leaf pictures in a complex environment are selected for testing.The experimental results show that the average detection accuracy rate reaches 93.95%and that the recall rate reaches 92.48%.The tea picking location method presented in this paper is more versatile and robust in complex environments. | Tao Wang Kunming Zhang Wu Zhang Ruiqing Wang Shengmin Wan Yuan Rao Zhaohui Jiang Lichuan Gu | 2023 | Information Processing in Agriculture2023，10，2： | 2 |
