BACKGROUND Concomitantly recorded Bispectral Index® (BIS) and Entropy™ values sometimes show discordant trends during general anaesthesia. Previously, no attempt had been made to discover which EEG characteristics cause discrepancies between BIS and Entropy. We compared BIS and Entropy values, and analysed the changes in the raw EEG signal during surgical anaesthesia with sevoflurane. METHODS...

Room-temperature ionic liquid (RTIL) electrolytes have attracted much attention for use in advanced, safe lithium-ion batteries (LIB) owing to their nonvolatility, high conductivity, and great thermal stability. However, LIBs containing RTIL-electrolytes exhibit poor cyclability because electrochemical side reactions cause problematic surface failures of the cathode. Here, we demonstrate that a...

Facile and convenient syntheses of bisdimethylthieno[2,3-b]thiophen-2,5-diyl bis(oxazole-2-amine), bis(1H-imidazol-2-amine), bis((3a)-H-indole),[1,2-a]pyrimidine), bis(1H-imidazo[1,2-b][1,2,4]triazole) and bis(9H-benzo[d]imidazo[1,2-a]imidazole) derivatives incorporating a thieno[2,3-b]thiophene moiety from the versatile and readily accessible 1,1'(3,4-dimethylthieno[2,3-b]thiophene-2,5-diyl)-b...

OBJECTIVE In the present study, we examined whether 2, 2-bis [4-(2-hydroxy-3-methacryloxypropoxy) phenyl] propane (Bis-GMA) has effects on LSC2 cells, human dental pulp cell line. MATERIAL AND METHODS The viability, cell cycle, and morphology of LSC2 cells were analyzed after exposure to several different concentrations of Bis-GMA. The recovery of viability of Bis-GMA exposed cells was also a...

PURPOSE To compare the depth of sedation determined by Ramsay sedation scale (RSS) with electroencephalogram-based bispectral index (BIS) and patient state index (PSI). MATERIALS AND METHODS Fifty mechanically ventilated cardiac surgical patients undergoing propofol and morphine sedation were assessed hourly for up to 6 hours or until tracheal extubation using the BIS, PSI, and RSS. Correlati...

The reactions of 1 - chloro - 2 - nitro benzene with 2 - Amino thio phenol yield the 2 - ( ( nitro phenyl ) thio ) aniline and then 2 , 2' - thio dianiline of this compound was prepared . Also the symmetrical potentially pentadentate N 2 O 2 S Schiff base ligand 2 , 2' - ( ( ( thio bis (1 , 2 - phenylene ) ) bis ( azanilidene ) ) bis ( methenilidene ) ) diphenol ( H 2 L ) obtain by added salicy...

UNLABELLED Bispectral index (BIS) is an electroencephalographic variable promoted for measuring depth of anesthesia. Electromyographic activity influences surface electroencephalography and the calculation of BIS. In this study, we sought to determine the effect of spontaneous electromyographic activity on BIS. BIS was monitored in three volunteers by using an Aspect A-1000 monitor. The experim...

Objective: The main objective of this study was to investigate the explicit memory bias in the people with high BAS/BIS sensitivity in the different manipulated mood states.  Methods: By using purposive sampling method, seventy-four participants (undergraduate students) were selected based on z-scores of 480 using the Carver and White’s BAS/BIS scale. They were distributed as: 24 wi...
