In this paper, the measurement of the viscosity of ZnO in ethylene glycol, propylene glycol, mixture of ethylene glycol and water (60:40 by weight), and a mixture of propylene glycol and water (60:40 by weight) and the thermal conductivity in ethylene glycol and propylene glycol as base fluids in the range of temperature from 25 ºC to 60 ºC are investigated. The results indicate that as the tem...

An amino acid type poly(ethylene glycol) is a useful tool for preparation of a bi- or multivalent poly(ethylene glycol) hybrid of bioactive peptides, but synthesis is problematic. The amino acid type poly(ethylene glycol) was prepared from poly(oxyethylene)diglycolic acid followed by introduction of a fluorenylmethyloxycarbonyl group. The resulting product could be purified easily by LH-20 colu...

The misuse of the commonly used chemical diethylene glycol (DEG) has lead to many poisonings worldwide. Methods were developed for analysis of DEG and its potential metabolites; ethylene glycol, glycolic acid, oxalic acid, diglycolic acid and hydroxyethoxy acetic acid in human urine, serum and cerebrospinal fluid samples, collected following a DEG-associated poisoning in the Republic of Panama ...

A short, monodisperse additive (octa(ethylene glycol) monophenyl ether) functions to suppress aggregation of thermally and chemically denatured lysozyme. Control studies with shorter and non-amphiphilic derivatives revealed that the amphiphilic structure is essential, and octa(ethylene glycol) is nearly the minimum chain length for amphiphilic poly(ethylene glycol)s to stabilize proteins.

Glass transition behavior of ternary disaccharide-ethylene glycol-water solutions, in reference to that of the binary combinations, has been investigated towards a better understanding of their cryoprotective ability. In water-deficient solutions, the disaccharides, including trehalose, sucrose and maltose, can associate with more than 100 ethylene glycol molecules to form amorphous complex, on...

BACKGROUND Increasing cell membrane permeability to water and cryoprotectants is critical for the successful cryopreservation of cells with large volumes. Artificial expression of water-selective aquaporins or aquaglyceroporins (GLPs), such as mammalian aquaporin-3 (AQP3), enhances cell permeability to water and cryoprotectants, but it is known that AQP3-mediated water and solute permeation is ...

BACKGROUND: Some herbal plants can prevent kidney stones formation in a dose dependent manner. In present study, we aimed to investigate the protective role of Cannabis sativa aqueous extraction on calcium oxalate formation in ethylene glycol-induced rats. MATERIALS AND METHODS: To evaluate anti-urolithiasis, variations of the main risk factors (citrate, phosphorous, calcium and PH) have been ...

To the Editor: We wish to substantiate the important observations of LeGatt and Tisdell (1) cautioning against the use of propylene glycol as an internal standard for quantifying ethylene glycol. A 32-yearold woman presented to our emergency department in an agitated state after the ingestion of multiple drugs in an attempted suicide. Gastric lavage and charcoal were administered as well as int...
