| 1 | Digital gene expression profiling analysis of DNA repair pathways in colon cancer stem population of HT29 cells显示文摘癌症干细胞(CSC ) 贡献新瘤损害的恶化和发展。当很可得到的临床的途径例如化学药品和放射治疗,将杀死癌症房间的多数时,他们都不杀死他们。一些抵抗房间象 CSC 一样,能由于他们的优秀自我维持的能力幸存,甚至在挑战性的环境。在现在的学习,我们响应单个海滨的损坏和双海滨从 HT29 房间线调查了冒号 CSC 的 DNA 修理基因的 mRNA 水平裂缝,以及在基础切除的关键基因的明显的 upregulation 修理,失配修理,非相应加入结束,并且在这些房间的相应再结合小径。数字基因表示分析在可以在 DNA 修理起重要作用的 CD44 + HT29 房间识别了 upregulated 基因。我们的结果表明冒号 CSC 忍受有效 DNA 修理能力,它可能在重复化学药品和放射治疗以后解释冒号 CSC 的幸存。 | Wenxue Wang Guoxiu Zhang Jing Yang Huan Gu Lei Ding Haijing Yu Min Yu Qinghua Cui Xinglai Ji Meizhang Li | 2017 | Acta Biochimica et Biophysica Sinica2017，49，1： | 1 |
| 2 | Pneumatic separation system for collected seedlings using subdivided air streams显示文摘To adhere to the needs of automated supply of collected seedlings for mechanized grafting and cutting machines for enhancing their operational efficiency,herein,a separation system that uses subdivided air streams to separate the collected seedlings is developed.The separation system comprises a feeder for supplying collected seedlings,a seedling separator that uses subdivided air streams,a picking belt for the separated seedlings,a delivery unit for the separated seedlings,a pneumatic unit,and a control unit.To investigate the complete performance of separation,picking,and delivery of the separation system,several separation experiments were conducted to separate the collected Anthurium seedlings.The results show that the consistency of the moving direction of seedlings floated by subdivided air streams in the separation container and the moving direction of the picking belt have a significant effect on the picking of the separated seedlings by the picking belt.Moreover,the seedling supply timing of the feeder has a significant effect on the stability of the collected seedling separation rate during continuous separation.When this timing is such that the percentage of separated seedlings is 70%,the separation rate of continuous separation operation is 2.24 plant/s(the separation productivity is 8060 plants/h)with 0.12 CV.The operating conditions are 0.5 MPa separation pressure,0.5 s nozzle operation time,and 60 mm seedling thickness in the separation container.Moreover,the staying times of the collected seedlings separated in the separation container are less than 2.5 min. | Delong Jiang Song Gu Qi Chu Yanli Yang Meizhang Gu Yi Yang | 2022 | International Journal of Agricultural and Biological Engineering2022，15，2： | 0 |
