background: nowadays colonoscopy has a very important role in screening colorectal cancers. in addition, adequate bowel preparation is critical to colonoscopy, as a poor preparation may obscure pathology or prevent full colonoscopy. as it is estimated that unsuccessful colonoscopy leads to second procedures in up to 20% of patients, we sought to compare the effects of different doses of polyeth...

background: fusion of dendritic cells (dcs) with melanoma cells could reinforce the antigenicity of tumors as a strategy for the treatment of malignant melanoma. however, the insufficient quantity of dcs and the low fusion efficiency limits the development of such approach. objective: to define the dosage of the stimulating factors as well as the induction condition for the optimal dcs preparat...

Polyethylene glycol was easily grafted to silica gel and used as a solid–liquid phase transfer catalyst in the reduction of aromatic nitro compounds. This silica-grafted polyethylene glycol is proved to be an efficient heterogeneous catalyst in the reduction of nitroarenes to the corresponding aromatic amines with zinc powder in water. The reduction reactions proceeded efficiently with exce...

Large volumes of Japanese encephalitis (JE) virus propagated in mouse brain can be easily purified by polyethylene glycol 6,000. By using the polyethylene glycol precipitation method, mouse hemoglobin was almost all separated from the viral suspension, and consequently the total amount of nonviral protein in the viral suspension decreased. The recovery of infectivity was about 100%. The removal...

to determine the effects of priming and planting density on improvement of morphological and physiological traits of the two hybrid corns sc (s.c. 704) under double cropping in sari, a split plot experiment as randomized complete block design with four replications was conducted in 2010. treatments included two densities of 80 and 100 thousand plants per hectare as the first factor and osmoprim...

We describe a rapid, reliable radioimmunoassay for unconjugated estriol in plasma. Polyethylene glycol (Carbowax 6000) is used to separate antibody-bound and free steroid. The assay is sensitive (25 pg for standards), precise, and accurate. At high and low concentrations of estriol, intra-assay coefficients of variation were 7.1% and 7.6%, respectively, and inter-assay coefficients of variation...

Polyethylene glycol 6000 precipitation was found to be an effective concentration method that enhanced the chances for detecting human virus pathogens in environmental samples. Percent recoveries from eluates of fresh and estuarine waters with 8% polyethylene glycol 6000 averaged 86 for hepatitis A virus, 77 for human rotavirus Wa, 87 for simian rotavirus SA11, and 68 for poliovirus. Percent re...

Human glycol ether poisonings are sparsely reported in the medical literature. We describe a healthy 22-month-old boy who accidentally drank up to 330 mL of brake fluid containing a 75% bleed of various glycol ethers (5%-50% polyethylene glycol monomethyl ether, 15%-40% triethylene glycol monoethyl ether, 1%-30% triethylene glycol monomethyl ether, 1%-25% triethylene glycol monobutyl ether, 1%-...

In some situations, endodontic infections do not respond to therapeutic protocol. In these cases, it is suggested the administration of an alternative intracanal medication that presents a wide spectrum of action and has an in-depth effect on the root canal system. The purpose of this study was to assess the antimicrobial action of ciprofloxacin, metronidazole and polyethylene glycol and natros...

Effective colonoscopy requires an adequate level of cleansing as a basic component. This review will describe a compact review about general considerations in bowel preparation for colonoscopy and specific considerations for various patients. A low-fiber diet instead of a regular diet on the day before colonoscopy is an independent predictor of adequate bowel preparation. Improved bowel cleansi...
