The chiral carbene bis[bis(R-1-phenylethyl)amino]cyclopropenylidene 2 and its dicarbene-silver complex [Ag(2)2]BF4 (3) have been isolated in good yields from the reactions of bis[bis(R-1-phenylethyl)amino]cyclopropenylium tetrafluoroborate (1)BF4 with potassium bis(trimethylsilyl)amide or with Ag2O, respectively; the molecular structures of (1)ClO4, 2 and 3 have been determined by X-ray diffrac...

BACKGROUND Awareness during anesthesia is a serious complication with potential long-term psychological consequences. Use of the bispectral index (BIS), developed from a processed electroencephalogram, has been reported to decrease the incidence of anesthesia awareness when the BIS value is maintained below 60. In this trial, we sought to determine whether a BIS-based protocol is better than a ...

Glioblastoma stem cells (GSCs) are a subpopulation of highly tumorigenic and stem-like cells that are responsible for resistance to conventional therapy. Bcl-2-intreacting cell death suppressor (BIS; also known as BAG3) is an anti-apoptotic protein that is highly expressed in human cancers with various origins, including glioblastoma. In the present study, to investigate the role of BIS in GSC ...

BACKGROUND Electromyographic activity has previously been reported to elevate the Bispectral Index (BIS) in patients not receiving neuromuscular blockade while under sedation in the intensive care unit. This study aimed to investigate the magnitude of the decrease of BIS following administration of muscle relaxant in sedated intensive care unit patients. METHODS The authors prospectively inve...

background: awareness and recall, though not common, are the major hazards of general anesthesia, especially in cesarean section (c/s) because of the absence of benzodiazepine and opioids for a significant time during anesthesia. in this study, the bispectral index (bis), end-tidal isoflurane, and hemodynamic parameters were examined to evaluate the depth of the routine general anesthetic techn...

BACKGROUND α-Bromination of the side chain of aromatic ketones using NBS in the presence of p-toluenesulfonic acid (p-TsOH) in acetonitrile is very common. However, regioselective bromination of bis and tris(ω-bromoacetophenones) with NBS in the presence of p-TsOH in acetonitrile under microwave irradiation is quite novel. The bis- and tris(ω-bromoacetophenones) are used in synthesis of bis and...

BACKGROUND Electroconvulsive therapy (ECT) is a highly effective and established treatment for depression. Magnetic seizure therapy (MST) has recently been developed and seems equally effective while associated with fewer side-effects. Both require general anaesthesia, which could be quantified using the bispectral index (BIS). We compared ECT and MST with respect to recovery times, left-sided ...
