BACKGROUND A patient presented with severe acidosis and a point-of-care lactate measurement of 42 mmol/L. Mesenteric ischemia was suspected, with a potential need for laparotomy; however, plasma lactate measurements were below 4 mmol/L. Ethylene glycol ingestion was subsequently diagnosed. We therefore wished to determine why discrepancies in lactate measurements occur and whether this "lactate...

The liquefaction of crop residues in the presence of ethylene glycol, ethylene carbonate, or polyethylene glycol using sulfuric acid as a catalyst was studied. For all experiments, the liquefaction was conducted at 160°C and atmospheric pressure. The mass ratio of feedstock to liquefaction solvents used in all the experiments was 30:100. The results show that the acid catalyzed liquefaction pro...

Considerable interest has recently been evoked in the study of proteins in nonaqueous solvents, very largely as a result of the observations of Rees and Singer (1) and Yang and Doty (2) that the internal configuration of protein molecules could be radically altered in nonaqueous media, as reflected by changes in sedimentation constants, viscosity increments, and optical rotatory dispersion. Of ...

Intercellular communication most likely plays a significant coordinating role in morphogenesis. Blockage of a specific type of intercellular communication, that mediated by gap junctions, has been proposed as a mechanism of action of some teratogens. Several glycol ethers have recently been shown to be teratogenic in laboratory animals. Because these compounds are negative in genotoxic assays, ...

Semen was diluted 1:9 with egg yolk-citrate medium containing 0.31--3.1 M (final concentration) formamide, butyramide, acetamide, propionamide, dimethylformamide, lactamide, malomide, ethylene glycol, trimethylene glycol, dimethylsulphoxide (DMSO) or glycerol. After 30 min incubation at 20 degrees C, sperm motility was superior in hypertonic solutions of acetamide, lactamide, dimethylsulphoxid...

The impurity analysis of ethylene glycol in hydroxyethyl starch (HES) was evaluated using the exact method and conditions described in the official EP 8.2 (2014) monograph [2]. The evaluation was performed using an ALEXYS® LC-EC analyzer for ethylene glycol, based on the DECADE Elite electrochemical detector and a SenCell with Au working electrode (WE) and HyREF (Pd/H 2 ) reference electrode. D...

The presence of ethylene glycol in used motor oil is an indication of antifreeze coolant leakage into the crankcase of an internal combustion engine, thus predicting engine-wear problems. Several options for the determination of glycols currently exist, including colorimetric tests which are easy to perform, but subjective in interpretation and not particularly sensitive, fast or cost effective...

Graft copolymer networks of poly(methacrylic acid-g-ethylene glycol) exhibiting pHdependent swelling behavior due to the formation of interpolymer complexes were prepared by free radical solution polymerization of methacrylic acid and poly(ethylene glycol) monomethacrylate. Dynamic swelling studies established the swelling/deswelling process due to hydrogen bonding. Additionally, the effects of...
