Objective: Spinal surgical procedures share the technical difficulty of having to preserve the integrity of the dura mater in a surgical field with different degrees of hemorrhage. This difficulty is particularly evident in the surgery of degenerative diseases.
Methods: We have developed a new surgical sucker that allows an easy dissection of the dural sac from adjacent structures and improves the overall surgical manipulation during degenerative lumbar spinal procedures. The present technical note describes this newly developed suction device that comprises a slightly oval spatula positioned at an angle of 30° to the bore of the suction tube.
Results And Conclusion: Attending to the combination of a spatula and a suction device, it offers several advantages when compared to the instruments that are currently available. Namely, it facilitates the dissection of the ligamentum flavum from the subjacent dura mater, separating and holding this ligamentum from the dura mater; it also allows a slight retraction of the dural sac without direct suction and a better illumination of the surgical field through light reflected from the spatula.

Purpose: This study aims to explore the neuroprotective effect of propofol in improving traumatic brain injury (TBI) by inhibiting ferroptosis through the modulation of the endothelial nitric oxide (NO) synthase (eNOS)/NO signaling pathway.
Methods: The GSE173975 dataset was used to analyze the differentially expressed genes between TBI and sham surgery control groups in the short and long term. A TBI model was established in 2-month-old male SPF C57BL/6 mice by impact exposure of the exposed dura mater.

The cerebrospinal fluid (CSF) border accommodates diverse immune cells that permit peripheral cell immunosurveillance. However, the intricate interactions between CSF immune cells and infiltrating cancer cells remain poorly understood. Here we use fate mapping, longitudinal time-lapse imaging and multiomics technologies to investigate the precise origin, cellular crosstalk and molecular landscape of macrophages that contribute to leptomeningeal metastasis (LM) progression.
