background & aims: endotracheal intubation is commonly performed in the intensive care unit. many international guidelines for difficult intubation management are available and the intensivists think that any endotracheal intubation in icu is potentially difficult with several complications. materials & methods: after obtaining ethical approval, this descriptive and analytical study was conduct...

introduction:ventilator- associated pneumonia(vap),as defined by the centers for disease control and prevention (cdc),is a pneumonia that occurs in a patient receiving mechanical ventilation that develops 48 hours or more after initiation of ventilation.re-intubation which occur within 72 hours of planned extubation may effect vap incidence.the aim of this study was to determine vap incidence i...

Silicone breast prostheses have been widely used for several decades. Until recently, about 150 000 women received these implants annually in the United States—80% for breast augmentation and the others almost exclusively for reconstruction after cancer surgery. There is little doubt about the beneficial psychological eVects of breast implants, but there is increasing awareness of alleged adver...

A quat-silicone micro-emulsion (particle size <40 nm), an amino-silicone macro-emulsion (110 nm), and an alkyl modified silicone macro-emulsion (740 nm) were used to modify Scots pine (Pinus sylvestris L.) sapwood. Treated and uncoated boards were exposed to natural weathering for one year along with water treated controls according to EN 927-3. The treatment with silicone emulsions did not enh...

Reworking electronic packages is an integral process related to diagnostics and salvaging valuable materials. It is a meticulous and time-consuming procedure that requires some knowledge of the package material composition to determine compatible cleaning solutions and processes. Silicone adhesives are being used more frequently due to their ability to minimize shear stress during temperature c...

PURPOSE To present the finding of tiny silicone oil droplets in 15 eyes of 15 patients after intravitreal injections of an anti-vascular endothelial growth factor agent or triamcinolone acetonide and to discuss the likely source of silicone oil. METHODS In an observational case series, charts of patients who had undergone intravitreal injections by one surgeon were reviewed retrospectively. T...

Abstract The main component of Silicone-based heat transfer fluids is modified silicone oil. high and low using temperature silicone-based better than hydrocarbon organic fluids. raising the maximum means that it can obtain higher steam in process system, power generation efficiency turbine will be improved remarkably if are used parabolic through solar system. It also increase a thermal plant,...

there are many studies about epidural fibrosis after surgical manipulation of the spine. we have studied formation of the post laminectomy epidural fibrosis after application of two materials (silicone and teflon) in this report. this expriment is on two groups of rats. two separated laminectomies were done in each rat, one serving as control while in the other laminectomy spaces silicone was u...
