使用多电极阵列系统（Med-64）于视网膜退化模型中检测局部视网膜失效的研究光刺激通过光感受器中的光转导信号来抑制视网膜暗电流。视网膜电图（Electroretinography (ERG)）虽可检测暗电流的堵塞 （视网膜电图a-波）。然而，标准视网膜电图代表了视网膜神经的综合平均活动信号，
血小板在在免疫应激中协助运送细菌
研究人员发现，血小板在驱动系统对作出反应的过程中发挥了重要作用，新成果发表在11月在线出版的《自然—免疫学》期刊上。 血小板的经典作用是它们参与了血凝反应。然而，Dirk Busch和同事指出，特定类型的细菌在中会被血小板迅速包裹，这一过程依赖于一种血小板所表达的分子GPIb。被包裹的细菌被
