“智能胶囊”可直运药物至大肠
智能胶囊 药物 大肠
2015/7/21
美国普渡大学研究人员开发出一种新的“智能胶囊”，可以直接运送药物到大肠进行靶向治疗。据物理学家组织网近日报道，相关研究报告即将发表在近期出版的电气和电子工程师学会(IEEE)《生物医学工程》杂志上。该研究由普渡大学电气和计算机工程教授芭芭克·齐伊和工业及药理学副教授鲁道夫·皮纳尔等人共同完成。齐伊说：“通常药物在到达病人大肠之前就被胃和小肠吸收了。然而有许多药物需要专门传递到大肠，因此我们的‘智能...
研究阐明近红外光线照射加速伤口愈合机制
近红外光线照射 加速伤口愈合
2015/7/15
近日，由德国乌尔姆大学Andrei Sommer领导的团队发现，用红光照射培养皿中的皮肤或细胞可提供即时的能量支持，有助于愈合伤口、缓解疼痛，并且有可能帮助治疗男性不育和其他医疗状况。几十年来，这种神奇的愈合效果早已众所周知，但它为何会起作用一直是个谜。事实证明，答案或许很简单，却又有些奇怪：红光似乎能改变水的物理性质，从而加快为细胞提供能量的化学反应。

Robert Heinzen第一次试图让贝氏柯克斯体菌自己生长却惨遭失败。这种会引发被称为Q热的类似流感状疾病的细菌，通常只在其感染的细胞中分裂。这迫使研究人员不得不在哺乳动物的组织中使其生长出来，并且阻碍了他们研究这种微生物的努力。当上世纪90年代初Heinzen在博士后期间试图找到一种不同的方式培养这种细菌时，他得到的只是半本潦草的笔记。

美国 可供移植 大鼠肢体
2015/6/4
在人造肾脏、肝脏、心脏先后获得成功后，科学家们再次向人工生物肢体发起冲击并取得了突破。日前，美国麻省总医院（MGH）研究人员描述了一种构建人工生物肢体的方法，并用这种方法成功培育出一个具有血管和肌肉组织的大鼠前肢。此外，他们还提供证据表明，同样的方法也适用于培育灵长类动物的肢体。此次研究可被看作是人类向人工生物肢体再造和移植迈出的第一步。相关论文发表在《生物材料》杂志网站上。

我希望自己的工作是在正确方向上的一个额外动力。我们所有人都希望文献的金字塔能牢固地建立在坚实的基础上。“我称自己为校正器。”美国科罗拉多大学遗传学家Christopher Korch说。他急切想校正的是已困扰生物医学研究半个多世纪的问题——实验室细胞培养遭到污染。在过去的15年间，Korch宣称78个被广泛使用的细胞系最终经证实长满了其他细胞。甲状腺细胞系实际上由黑色素瘤细胞组成，前列腺组织被膀胱...
