空间蛋白质组学的突破如何拯救生命

中毒性表皮坏死溶解症（TEN）是一种罕见的、但对抗生素或痛风治疗等常见药物的破坏性反应。这种疾病开始时并无大碍，通常只是皮疹，但会迅速升级为大面积皮肤脱落，类似于严重烧伤。尽管 TEN病情十分严重，但其基本机制仍然难以捉摸，治疗方案也仅限于支持性护理。TEN 的死亡率高达 30%，长期以来一直是临床医生的噩梦，直到现在才有了靶向疗法。

A Microvascular Surgeon’s View: How MyVeo Transforms Visualization

In this article, Dr. Andrew T. Huang, MD, FACS, otolaryngologist and a head and neck reconstructive surgeon, shares how digital 3D surgical visualization with the MyVeo headset from Leica Microsystems…

Optic nerve regeneration in the Xenopus laevis tadpole.

A Novel Laser-Based Method for Studying Optic Nerve Regeneration

Optic nerve regeneration is a major challenge in neurobiology due to the limited self-repair capacity of the mammalian central nervous system (CNS) and the inconsistency of traditional injury models.…

如何为深层肌肉组织中的轴突再生成像

这项研究重点介绍了亚伦-李（Aaron Lee）博士对截肢后肌肉移植中神经再生的定位研究。肢体缺失通常会导致生活质量下降，这不仅是因为组织缺失，还因为轴突再生紊乱引起的神经性疼痛。Mica组织学成像和荧光成像可帮助了解神经再生过程中轴突的生长和分支这项研究有助于塑造未来的神经假体接口设计，改善患者的治疗效果。

Capturing Developmental Dynamics in 3D

This application note showcases how the Viventis Deep dual-view light sheet microscope was successfully used by researchers for exploring high-resolution, long-term imaging of 3D multicellular models…

Some 2D measurements, e.g., lengths and areas, made on a PCB sample with a Leica measurement microscope using the Enersight software.

How to Select the Right Measurement Microscope

With a measurement microscope, users can measure the size and dimensions of sample features in both 2D and 3D, something crucial for inspection, QC, failure analysis, and R&D. However, choosing the…
