Sevoflurane is commonly used for cervical cancer surgery, but its effect on cervical cancer cell biology remains unclear. This mechanistic study explores how sevoflurane affects the proliferation and metastatic potential of immortalized cervical cancer cell lines. ⋯ Sevoflurane enhanced proliferation, migration, and invasion of immortalized cervical cancer cells, which was likely associated with increasing histone deacetylase 6 expression caused by phosphatidylinositide 3-kinase/AKT- and ERK1/2-signaling pathway activation.

Consciousness is supported by integrated brain activity across widespread functionally segregated networks. The functional magnetic resonance imaging-derived global brain signal is a candidate marker for a conscious state, and thus the authors hypothesized that unconsciousness would be accompanied by a loss of global temporal coordination, with specific patterns of decoupling between local regions and global activity differentiating among various unconscious states. ⋯ The global temporal coordination of various modules across the brain may distinguish the coarse-grained state of consciousness versus unconsciousness, while the relationship between the global and local signals may define the particular qualities of a particular unconscious state.
