'He is Down Here, Buzzing Around': Ontario Premier Swallows Bee Live During News Conference_我的网站

A |     胶质母细胞瘤是一种侵略性的癌症，五年内的存活率只有5%。

B |     Douglas Robert Ford Jr., the current premier of Ontario, ended up accidentally swallowing a bee as he was delivering a speech at a news conference, with the moment being captured on video.,In the footage, Ford can be seen speaking as the careless insect flies in front of his face, before suddenly darting straight into the politician’s open mouth.,To his credit, the premier seemed unperturbed by the sudden invasion of his orifice as he coughed and raised a hand to his face, apparently attempting to extricate the troublesome insect, before deciding to follow the opposite route and taking a swig from a water bottle.,“I just swallowed a bee,” Ford simply said when a member of the audience asked him what was wrong.,“I’m good. He’s down here, buzzing around right now,” he added, pointing at his stomach.,The politician appeared to be in good humor, joking that, “if that was in the clip, this is going to be replayed over and over again.”。

C | 它的治疗方法通常是通过手术切除肿瘤，然后进行放疗或化疗来清除任何剩余的细胞。不幸的是，这种癌症经常以对这些治疗有抵抗力的形式复发。但在一项新研究中，斯坦福大学的科学家们开发了一种创伤性较小的方法来治疗脑瘤，在小鼠的测试中，这种方法大大增加了生存时间。只需每天进行15分钟的治疗，持续15天，甚至在小鼠只是做他们平常的事情的时候。

D | 该技术是在一种新兴的治疗各种类型癌症的方法上发挥作用，该方法涉及将纳米粒子注入肿瘤，然后触发它们升温。触发器可以采取电磁场、超声波或光的形式，由于癌细胞对热量比健康细胞更敏感，这可以在对周围组织伤害最小的情况下杀死它们。斯坦福大学的新设备被设计为植入皮肤和颅骨之间，并在开启时发出红外光。由黄金制成的星形纳米粒子通过颅骨上的一个小孔被注入脑瘤，来自该设备的红外光将它们加热到5°C之多。经过几轮这样的治疗，癌细胞被成功杀死。该团队说，调整红外能量的功率以及光的波长可以使他们针对不同大小的肿瘤和大脑内的不同位置。在对小鼠的测试中，科学家们发现这种治疗方法能够减少大脑中的癌细胞，并大大延长动物的寿命--平均来说，是未接受治疗的小鼠生存时间的三倍。当化疗被添加到这个组合中时，小鼠的存活时间甚至更长。

E | 尽管到目前为止这项研究看起来很有希望，但当然很难将其结果推及到人类。但该团队希望扩大该设备的规模，以用于人类患者，作为对抗这种致命癌症形式的另一种武器。该研究发表在《自然-纳米技术》杂志上。
