Ubiquitin-proteasomal degradation of K/Cl cotransporter 2 (KCC2) in the ventral posteromedial nucleus (VPM) has been demonstrated to serve as a common mechanism by which the brain emerges from anesthesia and regains consciousness. Ubiquitin-proteasomal degradation of KCC2 during anesthesia is driven by E3 ligase Fbxl4. However, the mechanism by which ubiquitinated KCC2 is targeted to the proteasome has not been elucidated.

The mesopontine tegmental anesthesia area (MPTA) is a focal brainstem locus which, when exposed to GABAergic agents, induces brain-state transitioning from wakefulness to unconsciousness. Correspondingly, MPTA lesions render animals relatively insensitive to GABAergic anesthetics delivered systemically. Using chemogenetics, we recently identified a neuronal subpopulation within the MPTA whose excitation induces this same pro-anesthetic effect.

Background: Tachyphylaxis is the rapid development of drug tolerance following repeated administration.
Objectives: To evaluate the United States Food and Drug Administration Adverse Event Reporting System (USFDA AERS) data for drugs significantly associated with tachyphylaxis using disproportionality analysis.
Methods: Disproportionality analysis was used for detecting safety signals for identifying drugs associated with tachyphylaxis.

Background: Ciprofol, a novel intravenous anesthetic derived from propofol, exhibits high lipophilicity. Its pharmacokinetics and pharmacodynamics may vary across different body mass indices (BMI) categories, but data on its optimal dosing as well as its safety and efficacy during colonoscopy anesthesia in varying BMI groups are lacking.
Objective: To evaluate the efficacy and safety of ciprofol during anesthesia for painless colonoscopy in patients with varying BMI, and to explore the correlation between BMI and induction dose.

Background: The peri-operative period may create a biological environment conducive to cancer cell survival and dissemination. Microscopic residual tumours (micrometastases) can be dislodged even with excellent surgical technique. At the same time, the stress response from surgery can temporarily impair immune function and activate inflammatory processes, increasing the risk of tumour proliferation.
