the synthesis of some 9,10-disubstituted anthracene derivatives are described. 9,10-bis(2-bromoethyl) anthracene 4,9,10-bis (2-cyanoethyl) anthracene 5 and 9,10-bis (4-hydroxybutyl) anthracene 11 are synthesized for the first time.
An easy method was developed for the efficient preparation of diversely new 5,5-disubstituted N(3),N'(3)-linkaged bis-hydantoins. At first, using the same methods, some ketones and terephthalaldehyde were converted to several hydantoins and a new bis-hydantoin , respectively. Then 1,6-dibromohexane, as a mild reagent, was employed for the alkylation and incorporation of synthesized substrates t...
کاتالیزورهای استخلاف دار (bis-2-phindzrcl2) و بدون استخلاف (bis-indzrcl2) بر پایه لیگاند ایندنیل سنتز و برای ساخت کوپلیمرهای اتیلن و 1- هگزن به شکل همگن و ناهمگن استفاده شد. برای نگه داری کردن این کاتالیزورها از نوعی نگه دارنده نانوسیلیکاتی (mcm-41) استفاده شد. کاتالیزورهای متالوسن استخلاف دار (bis-2-phindzrcl2) در حالت همگن و نگه داری شده فعالیتی کمتر را در کوپلیمرشدن نسبت به کاتالیزور بدون اس...
Objective This study was performed to analyse factors influencing the effect-site concentration (Ce) of propofol at return of consciousness (ROC) with target-controlled infusion of propofol-remifentanil after laparoscopic surgery. Methods In total, 112 patients who underwent laparoscopic surgery under general anaesthesia were given propofol at the target concentration of 3.5 µg/ml. Remifentanil...
BACKGROUND Neuraxial anaesthesia in adults decreases the dose of i.v. or inhalational anaesthetic needed to reach a desired level of sedation. Furthermore, spinal anaesthesia alone has a sedative effect. The mechanism behind this phenomenon is presumed to be decreased afferent stimulation of the reticular activating system after sympatholysis. We hypothesized that this mechanism is equally acti...
AIM Although the precise nature of pathological gambling (PG) is still elusive, currently it is considered an impulse-control disorder that shares several features with substance dependence, such as deficit in self-regulation and impaired impulsivity. The aim of this study was to evaluate the impulsivity of PG patients by means of the Barratt Impulsivity Scale, version 11 (BIS-11), as compared ...
BACKGROUND Phaxan™ (PHAX, Chemic Labs, Canton, MA) is an aqueous solution of 10 mg/mL alphaxalone and 13% 7-sulfobutylether β-cyclodextrin (betadex). In preclinical studies, PHAX is a fast onset-offset IV anesthetic like propofol, but causes less cardiovascular depression. This first-in-man study was designed to find the anesthetic dose of PHAX and to compare it with an equivalent dose of propo...
Several studies have demonstrated that athletes show superior performance in general cognitive functions compared to non-athletes. However, the effects on function might vary depending athlete’s sport type. In athletes, visuospatial working memory is a crucial for immediate response each situation and experience. no yet examined association between types. This study aimed investigate whether ty...
BACKGROUND The aim of the study was to evaluate the comparative effects of propofol infusion versus sevoflurane for maintenance of anesthesia with respect to hemodynamics, recovery characteristics, nausea and vomiting in patients undergoing percutaneous nephrolithotomy. METHODS Forty American Society of Anesthesiologists physical status I-II patients, aged between 22 and 65 years were randoml...
A comatose patient required a tracheostomy. His Glasgow Coma Score was 4 and he was intubated with mydriatic and isochoric pupils, without corneal and light reflexes. Two previous EEGs showed signs of severe and diffuse encephalopathy (arreactive delta and theta rhythms) and there were no somatosensory evoked potentials recordable at the scalp. When the tracheostomy procedure was carried out, t...
