The aim of this study was to establish a standardized protocol for sleep endoscopy to differentiate obstruction patterns in obstructive sleep apnea (OSA). Target-controlled infusion (TCI) of the sedative was combined with real-time monitoring of the depth of sedation using bispectral analysis.

We applied repetitive transcranial magnetic stimulation (rTMS) to the unilateral hemisphere of rat brain, by placing a 25-mm figure-8 coil 1 cm lateral to the vertex on the biauricular line and angulating the coil by 45°. An in-house water cooling system was used for rTMS for more than 20 min.

The murine model of irreversible unilateral ureteric obstruction (UUO) is presented together with the model of reversible UUO in which the ureteric obstruction is relieved by anastomosis of the severed ureter into the bladder. These models enable the study of renal inflammation and scarring as well as tissue remodeling.

A reliable and repeatable way to produce a cervical unilateral spinal cord injury using the Infinite Horizon impactor is described. The method takes advantage of a custom designed frame and clamp to stabilize the spine. The standardized procedure and biomechanical injury parameters result in sufficient and sustained injuries.
FAQs
UBE separates visualization from instrument handling. The endoscope remains in one small portal to provide continuous views, while the surgeon uses the second portal for operative instruments. This arrangement allows direct control of the instruments rather than requiring all functions through a single access route, supporting treatment of spinal pathology while limiting disruption to tissues around the approach.
Saline irrigation serves both visualization and field-maintenance functions. It helps keep the operative view clear while washing away blood and tissue debris, allowing the endoscope to continue displaying the treatment area. This fluid-managed environment is therefore central to maintaining visibility during decompression, discectomy, or other procedures performed through the portals.
The smaller access routes may reduce muscle injury by limiting disruption of tissues around the surgical approach. This tissue-sparing feature may facilitate recovery, which is one reason minimally invasive access is relevant in spinal surgery. The benefit arises from the route used to reach the spine, while UBE still preserves direct instrument control and a familiar surgical workflow.
A typical UBE procedure coordinates three elements: small access routes, continuous endoscopic visualization, and instruments introduced through the separate working portal. Saline irrigation is maintained to clear blood and debris as the surgeon addresses the targeted spinal problem. The workflow can then be adapted to nerve decompression, disc removal, or selected fusion operations.
The technique supports nerve decompression and discectomy for spinal disorders such as stenosis and herniated discs. It can also be incorporated into selected spinal fusion operations. This range makes UBE relevant across procedures that require access to spinal structures, rather than limiting its use to a single diagnosis or operative goal.
Preserving direct instrument control lets the surgeon manipulate tools through a dedicated working portal while viewing the target continuously through the endoscope. This combination maintains a familiar surgical workflow rather than making visualization and instrument use depend on the same access route. In spinal surgery, that design supports procedures requiring both precise viewing and active tissue treatment.
