摘要
Chemoresistance is a common property of tumor-initiating cancer stem-like cells. Overcoming chemoresistance, particularly in cancer stem-like cells, can markedly enhance the efficacy of cancer therapy and prevent cancer recurrence and metastasis. This study demonstrates that temperature-negative expansion nanodrugs could achieve the controllable and enhanced release of anticancer drugs when combined with cryoablation and effectively overcome chemoresistance in mammary cancer stem-like cells. The enhanced destruction of both cancer stem-like cells and cancer cells resulted in the improved inhibition of second-generation tumor formation in vitro. Furthermore, nanodrug-mediated cryosurgery did not produce systemic toxicity and had superior antitumor effects in a xenograft tumor model. Collectively, this study demonstrates the strong potential of thermally sensitive nanodrug-mediated cryoablation for overcoming chemoresistance in cancer stem-like cells and markedly improving the overall treatment efficacy against breast cancer.

在Journal of Materials Chemistry B的封面中,出现了多彩的螺旋线,那这样的多彩螺旋线是如何实现的呢,本次课程就跟着图研科技一起来学习如何用Maya的螺旋线做出DNA链堆积的纳米球。
1.打开Maya软件,新建一个螺旋线。
2.根据需要,调节螺旋线的参数。
3.切换到面模式,给螺旋线四个不同的材质用不同颜色标出。
4.新建一个柏拉图多面体,调节其参数。
5.选择螺旋线,按mash按钮。
6.调节mash的参数,分布类型选择网格,方式为面中心,沿发现推动为2,输入网格为之前新建的柏拉图多面体,勾选泛洪网格按钮。
7.一个纳米球就做好了,给其灯光就可以渲染了。
结语:
对于科研工作者而言,做出优秀的科研成果的同时,将抽象、严谨的深奥知识,通过直观、形象的方式表现出来,找到有章可循的表达方式为自己的科研成果锦上添花十分重要,想要精准提升作图技能,科研绘图私教课火热报名中!
