An experimental procedure developed to concentrate fungal viruses from large volumes of homogenized mycelia with water-soluble polymers, such as polyethylene glycol, possesses advantages over more conventional methods. Concentration of the Penicillium stoloniferum fast-moving virus from mycelial homogenates after addition of polyethylene glycol was rapid and produced large quantities of pure vi...

Surface modification with polyethylene glycol (PEG) has been employed in the development of biomaterials to reduce unfavorable reactions. However, unanticipated body reactions have been reported, with activation of the complement system being suggested as having involvement in these responses. In this study, we prepared a PEG-modified surface on a gold surface using a monolayer of alpha-mercapt...

With many desirable features, such as being more effective and having multiple effects, antiangiogenesis has become one of the promising cancer treatments. The aim of this study was to design and synthesize a new targeted bioresponsive nanosystem with antiangiogenesis properties. The mUPR@Ru(POP) nanosystem was constructed by the polymerization of Ulva lactuca polysaccharide and N-isopropyl acr...

The inhibition of unspecific adhesion of human white blood cells is a prerequisite for applications requiring the control of defined surface interactions. In this study, a passivation agent based on polyethylene glycol (PEG) for glass surfaces was investigated for the use with human peripheral blood mononuclear cells (PBMC). The grafting of 2000 g/mol methoxy-terminated PEG-urea-triethoxysilane...

Large populations of larvae, required for many behavioral assays are difficult to be obtained by individual brush picking from the growth medium. Polyethylene glycol was found as a suitable replacement of sucrose, for density separation. Polyethylene glycol is a non-physiological agent and was found to have no adverse effect on olfactory response of the larvae.

We have synthesized a series of Ln(III)-containing polyethylene glycol conjugates and studied the structural and electronic properties of these complexes. These studies demonstrate that polyethylene glycol can be used to fine-tune water-exchange rates of Ln(III)-containing polyaminopolycarboxylate-type complexes; this control is desirable in developing Ln(III)-containing contrast agents for mag...

CONTEXT Colonoscopy is currently the gold standard method to examine the colon, the rectum and the terminal ileum. In order to perform the colonoscopy, it is necessary to clean the bowel and use medications that are generally poorly tolerated by the patients. OBJECTIVE Compare the tolerability, acceptability, safety and efficacy of two solutions used for intestinal preparation for a colonosco...

Polyethylene glycol dinitrates (PEGN) with molecular weights between 400 and 20 000 g·mol-1 were prepared from polyethylene glycols by esterification with nitric acid/sulfuric acid in dichloromethane. The products were characterized by gel permeation chromatography. The yield of PEGN increases with increasing reaction temperature (0-40 °C) however large liberation of nitrogen oxides was observe...

OBJECTIVE The objective of this study was to evaluate in an analytical and descriptive manner the evidence published so far on the use of polyethylene glycol (PEG), with or without electrolytes, in the management of functional constipation and the treatment of fecal impaction. METHODOLOGY Search on MEDLINE, EMBASE and Cochrane databases until May 2016 of all publications adjusted to the follo...
