杰夫·贝索斯(Jeff Bezos)在2月2日宣布辞去亚马逊公司(*** Inc.)首席执行官一职,这个决定可能意味着他要开启撒钱模式了。当时,作为身家接近2000亿美元的全球第二大富豪,他表示要把更多的时间用在慈善事业上。而最近,他又重回全球首富。他表示要把更多的时间用在慈善事业上。如果他真的这么做,就是在效仿约翰·涪克菲勒(John ***)、安德鲁·卡内基(Andrew Camegie)和比尔·盖茨(Bill Gates)等前辈的榜样,这些人都是在退出自己的企业之后才开始认真考虑如何捐出他们的财富的。

Radiotherapy is a cornerstone of anticancer treatment. However in spite of technical evolutions, important rates of failure and of toxicity are still reported. Although numerous pre-clinical data have been published, we address the subject of radiotherapy-stem cells interaction from the clinical efficacy and toxicity perspective. On one side, cancer stem cells(CSCs) have been recently evidenced in most of solid tumor primary locations and are thought to drive radio-resistance phenomena. It is particularly suggested in glioblastoma, where CSCs were showed to be housed in the subventricular zone(SVZ). In recent retrospective studies, the radiation dose to SVZ was identified as an independent factor significantly influencing overall survival. On the other side, healthy tissue stem cells radio-destruction has been recently suggested to cause two of the most quality of life-impacting side effects of radiotherapy, namely memory disorders after brain radiotherapy, and xerostomia after head and neck radiotherapy. Recent publications studying the impact of a radiation dose decrease on healthy brain and salivary stem cells niches suggested significantly reduced long term toxicities. Stem cells comprehension should be a high priority for radiation oncologists, as this particular cell population seems able to widely modulate the efficacy/toxicity ratio of radiotherapy in real life patients.
