Laser Ablation and Intravital Microscopy to Study Intestinal Remodeling09:42

Laser Ablation and Intravital Microscopy to Study Intestinal Remodeling

2.0K
Here, we present a method to obtain images of the intestine upon laser-induced wounding. By exposing the mouse intestine to a multiphoton laser, the loss of a single or multiple crypt(s) is induced locally. By repeatedly imaging the damaged area over months, the real-time dynamics of intestinal recovery is...

Focal Laser Ablation of Prostate Cancer: An Office Procedure11:07

Focal Laser Ablation of Prostate Cancer: An Office Procedure

8.4K
This article presents and describes an outpatient treatment for prostate cancer using focal laser ablation. Laser catheter placement is guided by MRI-ultrasound fusion imaging in a fashion similar to prostate needle biopsy. Treatment is monitored in real-time with a thermal probe, placed adjacent to the laser fiber.

In vivo Laser Axotomy in C. elegans

18.9K
A protocol to cut neurons in C. elegans with a MicroPoint pulsed laser is presented. We describe setting up the system, immobilizing worms, and severing labeled neurons. Advantages include a relatively low-cost system and the ability to sever neuronal processes or ablate cells in...
