Ethylene glycol ingestion, accidental or intentional, can be a life-threatening emergency. Assays are not available from most clinical laboratories, and, thus, results often require many hours or days to obtain. Enzymatic assays, adaptable to automated chemistry analyzers, have been evaluated, but they have been plagued by analytic problems. With an alternative method of data analysis applied t...

Erythrocytes from multiple sclerosis patients differ significantly (p less than 0.005) from those from controls with regard to hydrophobic affinity partition in two-polymer aqueous-phase systems containing dextran, poly(ethylene glycol) and poly (ethylene glycol)-fatty acid esters. The most likely source of the abnormality is the cell membrane.

The efficient conversion of biomass-derived glycolide into ethylene glycol over CuO in water was investigated. The reaction of glycolide was carried out with 25 mmol Zn and 6 mmol CuO with 25% water filling at 250 °C for 150 min, which yielded the desired ethylene glycol in 94% yield.

Here we report a detailed synthetic procedure for monodisperse octa(ethylene glycol) p-toluenesulfonate, a member of the heterobifunctional oligo(ethylene glycol) derivatives family. The method offers completely chromatography-free workup and purification, resulting in higher yields and a lower cost than any of the alternative strategies. We also introduce several upgrades, simplifying the meth...

abstract The stability of catalase in the reaction of hydrogen peroxide decomposition was studied in the presence of some potential stabilizers: ethylene glycol, glycerol, fructose, sucrose, fucose, ribitol and 2 nitro phenyl-#-D-galacto-pyranosid (niphegal). The sucrose, ethylene glycol and glycerol showed the best performance for long-term storage at 30°C. The stability of catalase increases ...

objectives: the antioxidant capacity impairs in kidney and urinary bladder of animals with stone disease. herbal medicine can improve the antioxidant condition of renal tissue. cynodon dactylon (c. dactylon) is a medicinal plant with antioxidative and diuretic properties and different preparations of this plant have shown promising effects in stone disease. assessment of the whole plant decocti...

in recent decade, the new advanced nanofluids, composed from various particles, have attracted the attention of researchers. this class of nanofluids, which can be prepared by suspending several types (two or more than two) of nanoparticles in base fluid, is termed as hybrid nanofluids. in this work, an experimental investigation on the effects of temperature and concentration of nanoparticles ...

objective: this study was carried out to investigate the preventive effects of hydroalcoholic extract of cynodon dactylon(c.dactylon) roots on calcium oxalate calculi in rat. materials and methods: 24 wistar rats were randomly divided into 4 groups: group a received tap drinking water while, groups b, c, and d received 1% ethylene glycol daily for 28 days. rats in groups c and d received ethano...
