生态护坡技术赋能乡村振兴的协同路径研究

Renmin Zhujiang
随着经济社会的发展，灌渠的功效也在发生着改变，不仅满足农业灌溉，防洪排水，还兼顾着改善生态环境的重任。以赣西北锦惠渠为研究对象，针对其清淤体系低效导致河道生态退化、渠顶工程废弃引发功能丧失、杂树杂草失控形成生态恶性循环以及 设备与资金短缺制约治理效能等问题，提出“技术升级-功能活化-机制创新”三重协同路径，把握“安全-生态-文化-经济”四维平衡。通过分级治理融合生态工法，打造集镇、村庄和郊野三级多功能廊道，引入智慧化管理创新运维模式，实现灌区功能的同时，将堤岸生物多样性指数从1.2增至2.5 ...

叶酸受体介导的载顺铂磁性纳米pH敏感药物的制备及性能

Zhongshan Daxue xuebao. Yixue kexue ban, 2014
摘 要: 【目的】 制备具有叶酸受体靶向?磁靶向及pH敏感释放的载顺铂磁性纳米药物(FA-PEG-NH-N=MNPs-CDDP),为进一步研发智能靶向头颈部肿瘤药物载体奠定基础?【方法】 采用化学共沉淀法制备醛基化海藻酸钠改性的四氧化三铁纳米粒(MNPs),海藻酸钠表面的羧基通过配位络合作用与顺铂连接,制备的偶联叶酸的双肼基PEG,其肼基端与海藻酸钠的醛基通过腙键连接包裹载药纳米粒,经纯化获得叶酸修饰的载顺铂磁性纳米pH敏感靶向抗癌药物 (FA-PEG-NH-N=MNPs-CDDP),采用紫外分光光度计?
