¹Aerospace and Mechanical Engineering, University of Arizona , ²Biomedical Engineering IDP and BIO5 Institute, University of Arizona

A versatile plasma lithography technique has been developed to generate stable surface patterns for guiding cellular attachment. This technique can be applied to create cell networks including those that mimic natural tissues and has been used for studying several, distinct cell types.

Medicine

Intraoperative Ultrasound in Spinal Surgery

Melissa M.J. Chua¹, Viren S. Vasudeva¹, Yi Lu¹

¹Brigham and Women's Hospital, Harvard Medical School

Here, we present a protocol on the use of intraoperative ultrasound in spinal surgery, particularly in cases of intradural lesions and lesions in the ventral spinal canal when using a posterior approach.

Here, we present a protocol to differentiate murine granulocyte-macrophage-colony-stimulating-factor-producing T helper (T_HGM) cells from naive CD4+ T cells, including isolation of naive CD4+ T cells, differentiation of T_HGM, and analysis of differentiated T_HGM cells. This method can be applied to studies of the regulation and function of T_HGM cells.

Neuroscience

Three-dimensional Navigation-guided, Prone, Single-position, Lateral Lumbar Interbody Fusion Technique

Samantha E. Hoffman¹, Saksham Gupta¹, Kevin Huang¹, Neil Klinger¹, Yi Lu¹

¹Department of Neurosurgery, Brigham and Women’s Hospital, Harvard Medical School

The single-position, prone, lateral approach allows for both lateral lumbar interbody placement and direct posterior decompression with pedicle screw placement in one position.
