Strongly thixotropic viscosity behavior of dimethylsulfoxide solution of polyrotaxane comprising α-cyclodextrin and low molecular weight poly(ethylene glycol)

Thermoreversible sol-gel transition of aqueous solution of polyrotaxane composed of highly methylated α-cyclodextrin and polyethylene glycol

Viscosity and Rheological Behavior of Ethylene Glycol-Maghemite Nanofluids

This work is devoted on the rheological behavior of ethylene glycol based nanofluids containing maghemtite nanoparticles. The size of these maghemite nanoparticles was measured using XRD and found to be about <50 nm. Major factors that influence on viscosity and rheological behavior, such as, temperature and particle mass concentration, were investigated over 25–80°C and 0.2 and 2% respectivel...

α, ω-Cholesterol-Functionalized Low Molecular Weight Polyethylene Glycol as a Novel Modifier of Cationic Liposomes for Gene Delivery

Here, three novel cholesterol (Ch)/low molecular weight polyethylene glycol (PEG) conjugates, termed α, ω-cholesterol-functionalized PEG (Ch2-PEGn), were successfully synthesized using three kinds of PEG with different average molecular weight (PEG600, PEG1000 and PEG2000). The purpose of the study was to investigate the potential application of novel cationic liposomes (Ch2-PEGn-CLs) containin...

Fatal aspiration of polyethylene glycol solution.

Endoscopy of the colon requires adequate cleansing of the entire bowel. Several laxative regimens have been propagated, but bowel preparation with polyethylene glycol (PEG) solution is popular because of the easy application and good cleansing results. Although very safe in daily use, complications of this bowel-cleansing procedure have been reported and aspiration of the PEG solution is a poss...

Low molecular weight polyethylene glycol induces chromosome aberrations in Chinese hamster cells cultured in vitro.

The human population is widely exposed to polyethylene glycol (PEG) and its chemical derivatives, which are widely used as vehicles or co-solvents in many pharmaceutical and cosmetic preparations. However, PEG polymers of low molecular weight differ significantly from polymers of higher molecular weight in their physico-chemical properties, biological effects on cell permeability and their abso...
