Color control of the multi-color printing device

INTRODUCTION During the development of printing technology, digital printing has played an important role. Now various kinds of multi-color digital inkjet printers are available. Compared with the conventional digital inkjet printer, the multi-color digital inkjet printer has larger color gamut and can faithfully produce more colors. The conventional color printing devices nor- mally use three or four inks, e.g., CMY, CMYK. Although some adopt more than four inks, e.g., CMYKLcLm, the…     

浅析邓小平的反腐败斗争理论

邓小平依法治理腐败思想是邓小平理论体系的重要组成部分,有着丰富的内容。邓小平认为,治理腐败,要标本兼治,既要重视治标,更要重视治本。邓小平不仅强调要依靠法制监督制约权力,还十分重视法律在惩治腐败中的作用,他认为惩治腐败靠“人治”是靠不住的,“法治”才靠得住些。他要求要完善法制,把反腐败斗争纳入法制化轨道。他强调指出,制定法律要完备,执行法律要严格,惩治腐败分子要严厉。

书香在线

在e—learning 渐成时尚的今天,传统的阅读方式和阅读习惯是否可以被完全取代?曾以自己作样本,有过为期一个月的极端阅读实验:在一切可利用的时间里,完全将自己“挂”在网络上,浏览教育网站或教育频道的学习资源,间或以新闻、笑话来放松自己……总之让自己拒绝阅读任何纸质载体的书刊杂志文件,体验一切都是在线阅读的滋味。     

让传统人文素养滋润中学生的精神世界

新颁布的《普通高级中学语课程标准》强调了语教育的人性。利用中学言教学,充分发挥中国古代学这一民族瑰宝在人素质中的影响是加强和改进未成年人思想道德建设、提高学生人素质的有效途径之一。

中学生物学教学应贯穿正确的思想观点

在中学生物学教学中经常能够听到类似“鸟为了飞翔而长有翅膀”的说法,“鸟”真的能够“为了飞翔而长有翅膀”吗?答案是否定的。在教学中,这是一种思想性错误,那么,为什么会出现思想性错误?1生物学教学中的思想性错误及其根本原因教学的思想性是指在教学中要用正确的观点阐述教     

Kinesin KIF4A is associated with chemotherapeutic drug resistance by regulating intracellular trafficking of lung resistance-related protein

Multidrug resistance (MDR) is the major impediment to cancer chemotherapy. The expression of lung resistance-related protein (LRP), a non-ATP-binding cassette (ABC) transporter, is high in tumor cells, resulting in their resistance to a variety of cytotoxic drugs. However, the function of LRP in tumor drug resistance is not yet explicit. Our previous studies had shown that Kinesin KIF4A was overexpressed in cisplatin (DDP)-resistant human lung adenocarcinoma cells (A549/DDP cells) compared with A549 cells. The expression of KIF4A in A549 or A549/DDP cells significantly affects cisplatin resistance but the detailed mechanisms remain unclear. Here, we performed co-immunoprecipitation experiments to show that the tail domain of KIF4A interacted with the N-terminal of LRP. Immunofluorescence images showed that both the ability of binding to LRP and the motility of KIF4A were essential for the dispersed cytoplasm distribution of LRP. Altogether, our results shed light on a potential mechanism in that motor protein KIF4A promotes drug resistance of lung adenocarcinoma cells through transporting LRP-based vaults along microtubules towards the cell membrane. Thus KIF4A might be a cisplatin resistance-associated protein and serves as a potential target for chemotherapeutic drug resistance in lung cancer.
