some new symmetrical tetraaza schiff base ligands containing 2-quinolinecarboxaldehyde moiety formed from condensation reaction of 2-quinolinecarboxaldehyde and o-phenylenediamine derivatives, such as n, nˊ-bis(2-quinolylmethylidene)-4-methoxy-1, 2-phenylenediimine (l1), n, nˊ-bis(2-quinolylmethylidene)-4-methy-1, 2-phenylenediimine (l2), n, nˊ-bis(2-quinolylmethylidene)-4-chloro-1, 2-phenylene...

PURPOSE Pediatric patients who receive both intramuscular (i.m.) sedation and general anesthesia (GA) for oral rehabilitation occasionally experience prolonged sedation and delayed discharge. The Bispectral Index System (BIS) is an EEG monitor that measures the level of sedation. The authors compared discharge times of patients who had BIS monitoring to those who did not to determine if the use...

Background: Major burns are life threatening. Fluid resuscitation is required for survival to maintain intravascular volumes and prevent hypovolemic shock. Bioimpedance spectroscopy (BIS) has been recognised as a potential method of monitoring fluid shifts after burn and in other disease states. The aims of this study were to examine the reliability of BIS across different dressing conditions a...

INTRODUCTION To obtain the optimal anesthesia depth is not easy in cardiovascular surgery patients where the haemodynamic reserve is limited, due to reasons such as not being able to give the desired dose of anesthetic agent, or the change in the pharmacokinetics of the agent in the heart-lung machine. This study was planned to assess the contribution of bispectral index (BIS) monitoring in the...

Developing a business information system (BIS) is a very complex process that involves not only the application of modern information and telecommunication technologies but, most important, a good understanding of its application domain: the organization. Nowadays, object oriented methods and languages are commonly used in many BIS development methodologies. However, most of these methods focus...

BACKGROUND Interventional bronchoscopic procedures are novel diagnostic and therapeutic methods in pulmonology, which may be unpleasant and dangerous to the patients; therefore, sedation and in some cases general anaesthesia are recommended. But adjusting the level of sedation is a challenge. In this study we intended to define a range of bispectral index (BIS) score suitable for these procedur...

Since that time, new data have become available, and these have been incorporated into the monograph and taken into consideration in the present evaluation. Chem. Abstr. Name: 1,2-Benzenedicarboxylic acid, bis(2-ethylhexyl) ester IUPAC Systematic Names: Bis(2-ethylhexyl) phthalate; phthalic acid, bis(2-ethyl-hexyl) ester Synonyms: Bis(2-ethylhexyl) 1,2-benzenedicarboxylate; bis(2-ethylhexyl) or...

New two nano- sized Schiff base complexes [M(L)], where L= 2, 2'-((1E, 1E')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and M=Cu or Zn, (a, b complexes) were synthesized by ultrasonic irradiation. These complexes were characterized by elemental analysis, molar conductivity, FT-IR, fluorescence emission, 1H NMR, field emission scanning electron spectroscopy...

In this research, Cu-phthalocyanine coated hybrid magnetic nanoparticles have been prepared in a simple method and evaluated as an efficient catalyst in the preparation of mono- and bis-pyrano[2,3-d]pyrimidinones and mono- and bis-2-amino-4H-pyrans from the condensation reaction of 1,3-dimethylbarbituric acid or 4-hydroxycumarin with malononitrile and mono- and bis-aldehydes under ultrasoni...
