We have studied the effects of nitrous oxide on EEG burst suppression patterns during stable isoflurane anaesthesia in 13 ASA I patients. After induction of anaesthesia with propofol, the concentration of isoflurane was increased with continuous EEG monitoring to burst suppression level (mean end-tidal concentration of isoflurane, 1.7 (SD 0.2)%), and kept constant during the study. During surge...

BACKGROUND AND OBJECTIVES Ketamine S(+) is important in pain modulation in surgical patients. The objective of the present study was to evaluate the relationship between the levels of sedation produced by low doses of ketamine S(+), as well as encephalographic variables: BIS, SEF 95%, pEMG, suppression rate, and presence of burst-suppression. METHODS Thirty patients of both sexes, aged 25-50 ...

Quasi-periodic Pedestal Burst Instabilities (PBIs), featuring alternative turbulence suppression and bursts, have been clearly identified by various edge diagnostics during I-mode to H-mode transition in the EAST Tokamak. The radial distribution of phase perturbation caused PBI shows that is localized pedestal. Prior each PBI, a significant increase density gradient close pedestal top can be di...

Murine Kupffer cells (KCs), which constitute one of the largest populations of tissue macrophages, differ from most other cells of the myelomonocytic lineage in lacking the capacity for a respiratory burst. A collagenase perfusion technique followed by adherence to plastic at low temperature yielded pure cultures of KCs uniformly expressing receptors for Fc and C3bi, and containing virtually no...
