组织中的精密空间蛋白质组学信息

尽管可使用基于成像和质谱的方法进行空间蛋白质组学研究，但是图像与单细胞分辨率蛋白丰度测量值的关联仍然是个巨大的挑战。最近引入的一种方法，深层视觉蛋白质组学（DVP），将细胞表型的人工智能图像分析与自动化的单细胞或单核激光显微切割及超高灵敏度的质谱分析结合在了一起。DVP在保留空间背景的同时，将蛋白丰度与复杂的细胞或亚细胞表型关联在一起。

使用克尔显微镜快速可视化钢中的磁畴

磁性材料中磁畴与偏振光相互作用后光的旋转，称为克尔效应，使得使用克尔显微镜对磁化样品进行研究成为可能。它可以快速可视化材料表面的磁域。对于用于电气和电子设备的磁性材料（例如钢合金）的高效研发和质量控制，克尔显微镜可以发挥重要作用。本文详细描述了如何使用克尔显微镜对钢合金晶粒中的磁域进行成像。

鼓室成形术：优选方法和工具

鼓室成形术用于修复鼓膜穿孔。鼓室成形术有五种类型。第一种鼓室成形术，也称为鼓膜成形术，仅限于鼓膜的修复，而不涉及中耳的其他手术操作。鼓膜成形术是一种常见的但往往被低估的手术。手术方法的选择取决于鼓膜穿孔的位置。良好的可视化是成功修复的关键。
