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...

اغلب کامپوزیت ها مخلوط فیزیکی مواد هستند که جسم توقویت شده ای را نتیجه می دهند. هدف برتر این پروژه ساخت مواد دندانی از نوع کامپوزیت می باشد. کامپوزیتهای دندانی را غالبا با عناوین رزین های پرشده رزین کامپوزیت می نامند. این مواد در اواسط دهه 1960 شناخته شدند اصطلاح کامپوزیت دندانی به شکل مرسوم بیانگر مخلوطی از شیشه های سیلیکات با مونومرهای آکریلی است که پلیمریزاسیون آنها هنگام اختلاط با شیشه آغاز...

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 ...

Bcl-2 interacting cell death suppressor (Bis), also known as Bag3 or CAIR-1, is involved in antistress and antiapoptotic pathways. In addition to Bcl-2, Bis binds to several proteins, suggesting it has diverse functions in normal and pathological conditions. To better define the physiological function of Bis in vivo, we developed bis-deficient mice with a cre-loxP system. Targeted disruption of...

INTRODUCTION Bispectral index (BIS) and state entropy (SE) are prone to artifacts, especially due to electrocautery (EC). We compared the incidence of artifacts in BIS and SE during surgery under local anesthesia and sedation. METHODS 28 females undergoing breast surgery under local anesthesia and sedation were studied. Simultaneous BIS and SE measurements were recorded every 10 seconds. Arti...
