Cross-linked polystyrene sulfonic acid and polyethylene glycol as a low-fouling material

Tri(propy1ene glycol) glycerolate diacrylate Cross-linked Polystyrene: Synthesis, Characterization and Functional Group Interconversions

Polyethylene glycol as a cause of anaphylaxis

BACKGROUND Polyethylene glycols (PEGs) or macrogols are polyether compounds and are widely used as additives in pharmaceuticals, cosmetics, and food. CASE REPORT We report on a Caucasian patient experiencing recurrent severe allergic reactions to several drugs. An extensive diagnostic workup including skin prick tests, intradermal tests (IDT) and a double-blind oral challenge was performed to...

Preparative purification of polyethylene glycol derivatives with polystyrene-divinylbenzene beads as chromatographic packing.

A clear and powerful chromatographic approach to purify polyethylene glycol derivatives at a preparative scale was reported, which was based on the polystyrene-divinylbenzene beads with ethanol/water as eluants. The validity of this method was verified with the reaction mixture of mPEG-Glu and mPEG propionaldehyde diethylacetal (ALD-PEG) as the model. The target products were one-step achieved ...

Optimization and Evaluation of Polyethylene Glycol Diacrylate as a Nonadsorptive Polymeric Material for Microfluidics

Polydimethylsiloxane (PDMS), commonly used in microfluidics, is susceptible to nonspecific adsorption of molecules and biological analytes, such as proteins. PDMS requires coating or chemical modification to overcome this problem. We optimized a single-monomer formulation of polyethylene glycol diacrylate (PEGDA), which upon polymerization to form polyPEGDA, provides reduced susceptibility to n...

A Meta-Analysis of Randomized Controlled Trials of Low-Volume Polyethylene Glycol plus Ascorbic Acid versus Standard-Volume Polyethylene Glycol Solution as Bowel Preparations for Colonoscopy

BACKGROUND Standard-volume polyethylene glycol (PEG) gut lavage solutions are safe and effective, but they require the consumption of large volumes of fluid. A new lower-volume solution of PEG plus ascorbic acid has been used recently as a preparation for colonoscopy. AIM A meta-analysis was performed to compare the performance of low-volume PEG plus ascorbic acid with standard-volume PEG as ...
